Description

FIELD OF TECHNOLOGY

[0001] This application relates to the field of terminal technology and, in particular, to a touch screen, an electronic device and a display control method.

BACKGROUND OF THE INVENTION

[0002] Currently, when a user answers a call with an electronic device such as a mobile phone or a smart watch, if the electronic device detects that an obstacle (such as a person's finger or face) is approaching the screen, the screen can be turned off, to prevent abnormal operation from occurring due to the user's face touching the screen when the user answers a call, and to conserve power of the electronic device; and when the electronic device detects that the obstacle is moving away from the screen, the screen can be turned on so that the electronic device can display information or receive an input operation from a user.

[0003] As the user's requirements for the screen-to-body ratio become higher, the border at the top of the screen of the electronic device narrows (or even disappears), and the non-contact light sensor cannot be placed. Therefore, the decision to implement non-contact detection by installing a non-contact photosensitive sensor on the edge of the screen of an electronic device is no longer applicable. In order to ensure that an electronic device with a narrow bezel or no bezel has a non-contact detection function, the prior art uses capacitive touch screen capacitance sensing technology to realize non-contact detection.

[0004] However, in actual applications, the capacitance data sensed by the touch screen is very sensitive to interference from the environment (e.g., deformation of the touch screen metal sheet, ambient temperature, ambient humidity, human sweat, and static electricity) and hence the accuracy non-contact detection is low, and furthermore, the control accuracy of the display of the electronic device is low, and the user experience is poor.

SUMMARY OF THE INVENTION

[0005] Embodiments of this application provide a touch screen, an electronic device, and a display control method in order to solve the technical problem in the prior art of relatively low accuracy of non-contact detection of an electronic device and low accuracy of electronic device display control.

[0006] According to a first aspect, a touch screen is provided, including a middle frame screen housing, a support member, a display module, and a touch module, wherein the middle frame screen housing forms a housing space, the display module is disposed in a housing space formed by the medium frame screen housing , and the touch module is located on the side of the display module, which is remote from the screen compartment of the middle frame; a metal sheet is located on the side of the display module that is adjacent to the middle frame screen compartment, and the edge of the metal sheet is attached to both the middle frame screen compartment and the display module; and the support member is disposed between the screen compartment of the middle frame and the metal sheet to support the metal sheet.

[0007] In this embodiment of the present application, when the position of the electronic device is changed, the support member can support the metal sheet, and the deformation of the metal sheet by gravity is weakened or prevented, so that the capacitance value detected by the sensor module can more accurately reflect the distance between the obstacle and touch screen, which improves the accuracy of non-contact detection and allows you to more accurately control the status of the touch screen display.

[0008] In an exemplary design, the first protrusion of the support member on the side of the sensor module and the second protrusion of the metal sheet on said side of the sensor module completely coincide with each other.

[0009] That is, in terms of the location range, the support member can be located on the entire surface within the coverage area of the metal sheet. Thus, the support member can support the entire surface of the metal sheet, so that the non-contact detection accuracy can be further improved, and the touch screen display state can be controlled more precisely.

[0010] In an exemplary design, the first protrusion of the sensor module-side support element is within the second protrusion of the metal sheet on the sensor module side, and the distance between the edge of the second protrusion and the center of the first protrusion is less than a predetermined value.

[0011] That is, the support member may be located only in a portion of the area within the coverage area of the metal sheet. In this way, the metal sheet can also be supported, the accuracy of non-contact detection can be improved, and the state of the touch screen display can be controlled more accurately; and the volume and weight of the support member is reduced, which contributes to lighter and thinner touch screen.

[0012] In an exemplary design, the support member includes a plurality of sub-components, and all of these sub-components are arranged at intervals in a first direction, the first direction being any direction perpendicular to the direction in which the display module and the touch module are stacked.

[0013] In this way, the entire surface of the metal sheet can be supported relatively evenly, so that the non-contact detection accuracy is improved, the state of the touch screen display can be controlled more precisely; and the volume and weight of the support member is reduced, which contributes to lighter and thinner touch screen.

[0014] In an exemplary design, the support member is a foam material with good electrical insulating characteristics.

[0015] In this way, the supporting member can have a good supporting strength, and negative influence on the other component can be avoided, which also contributes to making the touch screen lighter and thinner.

[0016] According to a second aspect, an electronic device is provided, the electronic device including a touch screen according to any of the first aspect or any of the possible designs of the first aspect.

[0017] Thus, when the position of the electronic device is changed, the support member in the screen can support the metal sheet, and the deformation of the metal sheet by gravity is weakened or prevented, so that the capacitance value detected by the touch module can more accurately reflect the distance between the obstacle and the touch screen , which improves the accuracy of non-contact detection and allows you to more accurately control the state of the touch screen display.

[0018] According to a third aspect, a display control method is provided, the method being applied to an electronic device, and the electronic device including a touch screen. The method includes: when it is determined that a user's gesture of moving the electronic device is a predetermined gesture, obtaining a capacitance measurement value sensed upon contact in a predetermined area of the touch screen, said predetermined area being in a peripheral edge area of the touch screen; and when the obtained capacitance measurement value satisfies the first predetermined condition, controlling the switching state of the touch screen display.

[0019] In this embodiment of this application, the processor selects a predetermined area on the touch screen to generate a capacitance measurement value to detect whether an obstacle is approaching or moving away from the touch screen, and then control the touch screen display state switching. Since the target area is in the peripheral edge area of the touch screen, and the effect of metal deformation on the capacitance measurement value generated in this area is relatively small, the calculation result (i.e., zoom in or out) is more accurate than the result (i.e., proximity or distance) obtained by calculation based on the capacitance value of the entire screen, so that it is possible to improve the accuracy of non-contact detection of the electronic device and control the display state of the electronic device more accurately.

[0020] In an exemplary construction, the first predetermined condition may include: The capacitance measurement value is in a monotonically increasing trend in the first period, and the capacitance measurement value at the end time of the first period exceeds the first predetermined threshold value. Accordingly, the touch screen display state switching control may include: controlling the touch screen display state to switch from an on screen to an off screen.

[0021] Thus, the accuracy of the electronic device's detection that an obstacle is approaching can be improved, and the electronic device can be controlled more accurately to switch from the on screen to the off screen.

[0022] In an exemplary construction, the first predetermined condition may include: The capacitance measurement value is in a monotonically decreasing trend in the first period, and the capacitance measurement value at the end time of the first period is less than the second predetermined threshold value. Accordingly, the touch screen display state switching control may include: controlling the touch screen display state to switch from an off screen to an on screen.

[0023] In this way, the accuracy of the electronic device's detection that an obstacle is approaching can be improved, and the electronic device can be controlled more precisely to switch from the off screen to the on screen.

[0024] According to a fourth aspect, a display control method is provided, the method being applied to an electronic device, and the electronic device including a touch screen. The method includes: when it is determined based on the first acceleration data that the gesture of the user to move the electronic device is a predetermined gesture, obtaining a capacitance measurement value taken by the touch screen in the second period, wherein the first acceleration data is acceleration data that refer to the electronic device in the first period and which are captured based on the first sampling rate; when the obtained capacitance measurement value satisfies the second predetermined condition, it is re-determined, based on the second acceleration data, whether the user's gesture to move the electronic device is said predetermined gesture, the second acceleration data being the acceleration data which is related to the electronic device in the third period and which are taken based on the second sampling rate, and the duration of the third period is greater than the duration of the first period and/or the first sampling rate is less than the second sampling rate; and when it is re-determined that the user's gesture for moving the electronic device is said predetermined gesture, controlling the switching state of the touch screen display.

[0025] In this embodiment of the present application, after determining that the obtained capacitance measurement value satisfies the second predetermined condition, the electronic device further adds the step of determining the gesture (that is, re-determining, based on the second acceleration data, whether the user's gesture is to move the electronic device specified gesture or not). Thus, even if the capacitance value sensed by the touch screen is affected by the environment, this gesture determination step can further ensure the accuracy of controlling the display of the electronic device and improve the user experience.

[0026] In an exemplary construction, the second predetermined condition includes the following: The capacitance measurement value is in a monotonically increasing trend in the second period, and the capacitance measurement value at the end time of the second period does not exceed the first predetermined threshold value. Accordingly, the touch screen display state switching control may include: controlling the touch screen display state to switch from an on screen to an off screen.

[0027] Thus, the accuracy of the electronic device's detection that an obstacle is approaching can be improved, and the electronic device can be controlled more accurately to switch from the on screen to the off screen.

[0028] In an exemplary construction, the second predetermined condition includes the following: The capacitance measurement value changes in a monotonically decreasing trend in the second period, and the capacitance measurement value at the end time of the second period is not less than the second predetermined threshold value. Accordingly, the touch screen display state switching control includes: controlling the touch screen display state to switch from an off screen to an on screen.

[0029] Thus, the accuracy of the electronic device's detection that an obstacle is approaching can be improved, and the electronic device can be controlled more precisely to switch from the off screen to the on screen.

DESCRIPTION OF EMBODIMENTS

[0050] As described in the prior art, in the traditional technical solution, non-contact detection of an electronic device is usually implemented by installing a non-contact photosensitive sensor in a frame above the screen of the electronic device. The non-contact light sensor usually includes two parts: One part is a Light Emitting Diode (LED), which is used to emit near infrared light; and the other part is a light sensitive sensor which is sensitive to near infrared light. When an obstacle approaches the electronic device, the light-sensitive sensor will receive more near-infrared light, and when the near-infrared light received by the light-sensitive sensor exceeds the upper limit, the screen turns off. When the obstacle moves away from the electronic device, the light sensor will receive less near infrared light, and when the near infrared light received by the light sensor is less than the lower limit, the screen turns on. However, as the screen-to-body ratio of the electronic device constantly increases, the frame above the screen becomes narrower (or even disappears), and the non-contact light sensor cannot be placed. In order to ensure that such an electronic device also has a non-contact detection function, some existing technologies propose to use capacitive touch screen capacitance sensing technology to realize non-contact detection.

[0051] FIG. 1A and FIG. 1B are schematic structural representations of the touch screen of an electronic device in the prior art. Referring to FIG. 1A and FIG. 1B, the touch screen includes a middle frame screen box 11, a display module 12 located in the accommodation space formed by the middle frame screen box 11, and a touch module 13 located above the display module. The metal sheet 14 is located on the side of the display module 12 that is adjacent to the base of the middle frame screen box 11, and the edge of the metal sheet 14 is bonded and attached to both the middle frame screen box 11 and the display module 12 with an adhesive. FIG. 1A and FIG. The 1B black fill part is used to represent the adhesive. The metal sheet 14 can better secure the display module 12 to ensure the stability of the display module 12.

[0052] When an obstacle approaches or moves away from the touch screen within a certain range from the touch screen, the capacitance value of the capacitive sensor at the corresponding contact position on the touch module 13 changes (for example, the capacitance value increases when the obstacle approaches the touch screen and decreases, when the obstacle moves away from the touch screen, and the capacitance value is highest when the obstacle is in contact with the touch module 13). Therefore, in principle, non-contact detection can be realized by detecting the capacitance value change rule on the sensor module 13.

[0053] However, in actual application, the capacitance value sensed by the touch screen is very sensitive to interference from the environment, such as deformation of the metal sheet in the touch screen, ambient temperature, ambient humidity, obstruction sweating, and static electricity.

[0054] The deformation of the metal sheet is used as an example: When an electronic device approaches or moves away from an obstacle, the position of the electronic device usually changes, for example, the user picks up, puts down or turns over the electronic device when answering a call. Since the middle area of the metal sheet 14 in the touch screen is not fixed with adhesive, it will be deformed by gravity to a greater extent. When the electronic device is in different positions, the degree of deformation of the metal sheet 14 is also different. For example, FIG. 2A, FIG. 2B and FIG. 2C are schematic representations of situations where the screen of an electronic device is facing up, perpendicular to the horizontal direction, and facing down, respectively. When the screen of the electronic device is facing up, as shown in FIG. 2A, the distance between the metal sheet 14 and the sensor module 13 is increased. When the screen of the electronic device is facing down, as shown in FIG. 2C, the distance between the metal sheet 14 and the sensor module 13 is reduced. When the screen of the electronic device is perpendicular to the horizontal direction, as shown in FIG. 2B, the amount of change in the distance between the metal sheet 14 and the sensor module 13 is relatively small. When the metal sheet 14 is deformed to a different degree, a different inductive capacitance is created between the metal sheet 14 and another metal layer in the electronic device, so that the capacitance value of the capacitive sensor on the sensor module 13 is affected by a different degree.

[0055] In general, the capacitance value generated by the touch module 13 when an obstacle is near but not in contact with the touch screen is much smaller than the capacitance value generated by the touch module 13 when the obstacle is in contact with the touch screen. In the scenario in which the touch module 13 was used only for touch detection (for example, for detecting an input operation performed by a user) in the past, since the absolute value of the capacitance value generated when an obstacle is in contact with the touch screen is relatively large (capacitance value obtained when the obstacle is in contact with the touch screen (i.e., the capacitance value obtained when the distance between the obstacle and the touch module 13 is 0 mm) is indicated here as 100%), a threshold value used to detect whether the obstacle in contact with the touch screen is set to a relatively large value, and the capacitance effect caused by the environmental factor (for example, the capacitance effect caused by the deformation of the metal sheet 14) is usually about 20% of the capacitance value obtained when the obstacle is in contact with the touch screen and can therefore be lowered. However, in the scenario in which the touch module 13 is used for non-contact detection, when an obstacle is close to the touch screen but not in contact with the touch screen (the distance between the obstacle and the touch module 13 is approximately in the range of 20 mm to 5 mm), the absolute value the value of capacitance generated by the sensor module 13 is relatively small and typically ranges from 1% to 4% of the capacitance value when an obstacle contacts the sensor module 13. detection of the touch module 13. Therefore, in the prior art, the proximity detection accuracy of an obstacle based on the touch screen is relatively low, resulting in poor control accuracy of the display of the electronic device, and problems such as incorrectly turning on the screen or turning off the screen incorrectly occur frequently. Therefore, the consumed power of the electronic device is greatly consumed and the user experience is poor.

[0056] In view of this, the embodiments of this application provide the following three solutions for improving the accuracy of controlling the display of an electronic device.

[0057] In the first solution, the supporting member may be located between the metal sheet 14 and the middle frame screen compartment 11 in the electronic device touch screen assembly shown in FIG. 1A and FIG. 1b. The support member supports a part of the metal sheet that is subject to deformation and can effectively resist or avoid deformation of the metal sheet, so as to improve the non-contact detection accuracy of the electronic device and moreover control the display state of the electronic device more accurately.

[0058] In the second solution, when non-contact detection is performed based on the touch screen structure of the electronic device shown in FIG. 1A and FIG. 1B, and based on the capacitance value generated by the touch module 13, to calculate the distance between the obstacle and the touch screen, the capacitance value sensed in the corresponding edge area of the metal plate 14 (i.e., the area that is not subject to deformation) in the touch module can be selected. 13 (for example, the capacitance value sensed in the first three lines of contact positions on the sensor module 13). The edge region of the metal sheet 14 is not subject to deformation. Therefore, the effect on the capacitance value corresponding to this area can be relatively small, and the result of the calculation (i.e. approach or distance) is more accurate than the result (i.e. approach or distance) obtained by calculation based on the value of the entire screen capacity, so that the non-contact detection accuracy of the electronic device can be improved and the display state of the electronic device can be controlled more accurately.

[0059] In a third solution based on the touch screen structure of the electronic device shown in FIG. 1A and FIG. 1B, after the ratio of the distance between the obstacle and the electronic device, which is calculated based on the capacitance value sensed by the sensor unit 13, satisfies the condition for turning off/on the screen, a gesture determination step is added: determining, based on the position change of the electronic device, whether the event is , in which an obstacle approaches or moves away from an electronic device, occurring randomly; and after determining that the event does not occur by chance, which is equivalent to determining that the user has an intention to move the electronic device closer to or further away from the human body, turning off/on the screen. Thus, even if the capacitance value sensed by the touch screen is affected by the environment, this gesture determination step guarantees the accuracy of controlling the display of the electronic device, so that the user experience is improved.

[0060] It should be noted that in this embodiment of this application, the above three solutions can be implemented separately or can be implemented in combination with each other. In this embodiment of the present application, this is not particularly limited.

[0061] The following describes the technical solutions in the embodiments of this application with reference to the accompanying drawings in the embodiments of this application. "At least one" in the embodiments of this application means one or more, and "many" means two or more. In addition, it should be understood that in the description of this application, words such as "first" and "second" are used only for the purposes of distinguishing the description, they should not be understood as indicating or implying relative importance and should not be understood as indicating or implying a sequence .

[0062] The technical solutions provided in the embodiments of this application can be applied to electronic devices such as a mobile phone, tablet computer, desktop computer, laptop computer, ultra-mobile personal computer (UMPC), handheld computer, netbook, personal digital assistant (PDA), wearable electronic device and virtual reality device. In embodiments of this application, this is not particularly limited.

[0063] Based on the example in which the electronic device is a mobile phone, FIG. 3 is an exemplary schematic structural representation of a mobile phone. As shown in FIG. 3, the mobile phone 100 may include a processor 110, an external memory interface 120, an internal memory 121, a universal serial bus (USB) interface 130, a charge control module 140, a power control module 141, a battery 142, an antenna 1, an antenna 2, mobile communication module 150, wireless communication module 160, audio module 170, speaker 170A, receiver 170B, microphone 170C, headset interface 170D, sensor module 180, key 190, motor 191, indicator 192, camera 193, display 194, and module interface 195 subscriber identification module (SIM). The sensor module 180 may include a pressure sensor 180A, a gyro sensor 180B, a barometric pressure sensor 180C, a magnetic sensor 180D, an acceleration sensor 180E, a distance sensor 180F, a fingerprint sensor 180H, a temperature sensor 180J, a touch sensor 180K, an ambient light sensor 180L, 180M bone conduction sensor, etc.

[0064] It can be understood that the structure shown in this embodiment of this application is not a specific limitation for mobile phone 100. In some other embodiments of this application, mobile phone 100 may include more or fewer components than shown in the figure, or some components may be combined, or some components may be separated, or a different arrangement of components may be used. The components shown may be implemented in hardware, software, or a combination of software and hardware.

[0065] Processor 110 may include one or more processing units. For example, processor 110 may include an application processor (AP), a modem processor, a graphics processing unit (GPU), an image signal processor (ISP), a controller, a memory, a video codec, a digital signals (digital signal processor, DSP), baseband processor and/or neural network processing unit (NPU). The various processing units may be independent devices or may be integrated into one or more processors.

[0066] The controller may be the nerve center and command center of the mobile phone 100. The controller may generate an operating control signal based on the instruction's operating code and time sequence signal to control instruction retrieval and execution of instructions.

[0067] Memory may also be placed within processor 110 to store instructions and data. In some embodiments, the memory in processor 110 is a cache. The memory may store an instruction or data that has just been used or is being cycled by the processor 110. If the processor 110 needs to use the instruction or data again, the instruction or data may be directly recalled from the memory. Re-access is avoided and the processor 110 wait time is shortened, thereby improving system efficiency.

[0068] The processor 110 may execute the display control method provided in this embodiment of this application. The processor 110 may determine, based on the trend of the capacitance value of the touch screen, the trend of change (ie, approaching or moving away) of the distance between the obstacle and the touch screen. For example, when the distance between the obstacle and the touch screen becomes smaller (that is, approaching is performed), the contact capacitance value at which the touch screen is close to the obstacle increases; or when the distance between the obstacle and the capacitive touch screen becomes larger (ie, moving away), the contact capacitance value at which the touch screen is close to the obstacle decreases. Upon determining that the distance between the obstacle and the capacitive touch screen satisfies a predetermined condition, the processor 110 controls the touch screen to perform the predetermined operation, such as turning the screen on or turning off the screen.

[0069] In some embodiments, the processor 110 may further determine, after determining that the distance between the obstacle and the touch screen satisfies the predetermined condition, whether the gesture performed by the user on the electronic device is the predetermined gesture. The touch screen is controlled to perform the predetermined operation only when it is determined that the distance between the obstacle and the touch screen satisfies the predetermined condition and the gesture performed by the user on the electronic device is the predetermined gesture. For example, the processor 110 may determine, based on the acceleration data output from the acceleration sensor 180E, a gesture performed by the user on the electronic device, such as raising, lowering, or flipping the electronic device. In addition, the processor 110 turns off the touch screen only after detecting that an obstacle is approaching the touch screen and determining that the gesture performed by the user on the electronic device is lift to reduce the power consumption of the terminal device, and turns on the touch screen only after detecting that that the obstacle is moving away from the touch screen, and determining that the gesture performed by the user on the electronic device is to lower so that the user can operate the electronic device. Thus, the display control accuracy of the electronic device can be improved and the user experience can be improved.

[0070] In some embodiments, processor 110 may include one or more interfaces. The interface may include an inter-integrated circuit (I2C) interface, an inter-integrated circuit sound (I2S) interface, a pulse code modulation (PCM) interface, a universal asynchronous receiver/transmitter (UART), mobile industry processor interface (MIPI), general-purpose input/output (GPIO), subscriber identity module interface (subscriber identity module, SIM), universal serial bus (USB) interface, and/or the like.

[0071] The I2C interface is a bidirectional synchronous serial bus, including a serial data line (serial data line, SDA) and a serial clock line (serial clock line, SCL). In some embodiments, processor 110 may include multiple I2C bus groups. The processor 110 can be separately connected to the touch sensor 180K, charger, flash, camera 193, and the like using various I2C bus interfaces. For example, the processor 110 may be connected to the touch sensor 180K through the use of an I2C interface, so that the processor 110 communicates with the touch sensor 180K through the I2C bus interface, thereby realizing the contactless detection function of the mobile phone 100.

[0072] The I2S interface may be used for audio communications. In some embodiments, processor 110 may include multiple I2S bus groups. The processor 110 may be coupled to the audio module 170 using the I2S bus to enable communication between the processor 110 and the audio module 170. In some embodiments, the audio module 170 may transmit an audio signal to the wireless module 160 using the I2S interface to implement a call answering function using Bluetooth headsets.

[0073] The PCM interface can also be used for audio communication, as well as sampling, quantization and coding of the analog signal. In some embodiments, audio module 170 may be connected to wireless communication module 160 using a PCM bus interface. In some embodiments, the audio module 170 may also transmit an audio signal to the wireless module 160 using the PCM interface to implement call answering functionality using a Bluetooth headset. Both the I2S interface and the PCM interface can be used for audio communication.

[0074] The UART interface is a universal serial data bus used for asynchronous communication. The bus may be a bi-directional communication bus. The bus is configured to convert data to be transmitted between serial communication and parallel communication. In some embodiments, the implementation of the UART interface is usually configured to connect the processor 110 to the module 160 wireless.

[0091] FIG. 4 is a possible schematic structural representation of a touch screen according to an embodiment of this application. The touch screen includes a middle frame screen box 31, a display module 32 located in the accommodation space formed by the middle frame screen box 31, and a touch module 33 located above the display module 32. The metal sheet 34 is located on the side of the display module 32 that is adjacent to the base of the mid-frame screen box 31, and the edge of the metal sheet 34 is attached to both the mid-frame screen box 31 and the display module 32 (for example, can be attached with adhesive). The metal sheet 34 can ensure the stability of the display module 32. The touch screen further includes a support member 35, which is located on the side of the screen shell 31 of the middle frame that faces the display module 32 and is under the metal sheet 34. When the position of the electronic device is changed, the support member 35 supports the metal sheet 34, weakens or even prevents the metal sheet 34 from being deformed by gravity, so that the capacitance value detected by the touch module 33 can more accurately reflect the distance between the obstacle and the touch screen, thereby improving the accuracy of non-contact detection of the electronic device and controlling the display state of the electronic device in a more precise manner.

[0092] For example, the material of the support member 35 can be implemented in a variety of ways, such as foam with good electrical insulating characteristics or other electrical insulating material (eg, polyethylene terephthalate or polyfluoroethylene). With regard to the range of location, the support member 35 may be located on the entire surface within the coverage area of the metal sheet 34, or may be located only on a partial area within the coverage area of the metal sheet 34 (for example, in an area with a relatively large degree of deformation due to gravity ).

[0093] For example, referring to FIG. 5A, the support member 35 is positioned over the entire surface within the coverage area of the metal sheet 34.

[0094] For example, referring to FIG. 5B, the support member 35 is located only in the central region (the position that is subject to gravity deformation) of the metal sheet 14 within the scope of the metal sheet 34.

[0095] For example, referring to FIG. 5C, the support member 35 may include a plurality of sub-components, and these sub-components are spaced within the coverage area of the metal sheet 34.

[0096] Certainly, in a particular embodiment, the shape and size of the support member 35 may be implemented in another way. In this embodiment of the present application, this is not particularly limited.

[0097] The mobile phone 100 can detect, with each contact of each touch screen, a capacitance value sensed when an obstacle approaches or moves away from the touch screen. When the mobile phone 100 detects that the capacitance value is within the predetermined range, it can be determined that there is an obstacle nearby. When it is found that the capacitance value tends to decrease, it can be determined that the obstacle is moving away from the touch screen; or when it is found that the capacitance value tends to increase, it can be determined that an obstacle is approaching the touch screen. Thus, the mobile phone 100 can detect, using the touch screen, that the mobile phone 100 held by the user is brought closer to the ear to make a call, so that the screen automatically turns off to save power, or detect that the mobile phone 100 held by the user is moved away from the ear. ear so that the screen automatically turns on for user operations.

[0099] The ISP is configured to process the data returned by the camera 193. For example, when photographing, the shutter is opened, light is transmitted to the light-sensitive element of the camera using a lens, the optical signal is converted into an electrical signal, and the light-sensitive element of the camera transmits the electrical signal on the ISP for processing to convert the electrical signal into an image visible to the naked eye.

The light-sensitive element can be a charge coupled device (CCD) or a phototransistor based on a complementary metal-oxide-semiconductor (CMOS) structure. The light sensing element converts the optical signal into an electrical signal and then passes the electrical signal to the ISP for conversion into a digital image signal. The ISP outputs the digital image signal to the DSP for processing. The DSP converts the digital image signal into a standard image signal in a format such as RGB or YUV. In some embodiments, mobile phone 100 may include one or N cameras 193, where N is a positive integer greater than 1.

The processor 110 executes various functional applications and data processing of the mobile phone 100 by executing an instruction stored in the internal memory 121. The internal memory 121 may include a program storage area and a data storage area. The program storage area may store an operating system, an application program required by at least one function (eg, a sound reproduction function or a picture reproduction function), or the like. The data storage area may store data (such as audio data or a phone book) generated during use of the mobile phone 100. In addition, the internal memory 121 may include high-speed random access memory, and may also include non-volatile memory such as at least at least one magnetic disk storage device, flash memory device, or universal flash storage (UFS).

Mobile phone 100 may be provided with at least one microphone 170C. In some other embodiments, the mobile phone 100 may be provided with two microphones 170C to provide a noise canceling function in addition to picking up the audio signal. In some other embodiments, the mobile phone 100 may alternatively be provided with three or more microphones 170C to identify the sound source and implement a directional recording function in addition to the audio pickup and noise reduction.

[00111] The headset interface 170D is configured to connect to a wired headset.

[00112] The pressure sensor 180A is configured to sense a pressure signal and can convert the pressure signal into an electrical signal. In some embodiments, the pressure sensor 180A may be located on the display 194. There are many types of pressure sensors 180A, such as a resistive pressure sensor, an inductive pressure sensor, and a capacitive pressure sensor. The capacitive pressure sensor may include at least two parallel plates having a conductive material. When a force is applied to the pressure sensor 180A, the capacitance between the electrodes changes. The mobile phone 100 determines the force of pressure based on the capacitance change. When a touch operation is performed on the display 194, the mobile phone 100 detects the strength of the touch operation using the pressure sensor 180A. The mobile phone 100 can also calculate the touch position based on the detection signal of the pressure sensor 180A. In some embodiments, a touch operation that affects the same touch position but has a different touch operation strength may correspond to different operating instructions. For example, when a touch operation whose touch operation strength is less than the first pressure threshold affects the short message application icon, an instruction for viewing the short message is executed. When a touch operation whose touch operation strength is greater than or equal to the first threshold value is performed on the short message application icon, an instruction for creating a new short message is executed.

[00113] The gyro sensor 180B may be configured to determine the position of the mobile phone 100 while moving. In some embodiments, the angular velocity of mobile phone 100 about three axes (ie, x, y, and z axes) may be determined using gyro sensor 180B. The gyro sensor 180B may be configured to perform image stabilization during photography. For example, when the shutter is pressed, the gyro sensor 180B detects the shake angle of the mobile phone 100 and calculates, based on this angle, the distance to be compensated by the lens module so that the lens counteracts the shake of the mobile phone 100 by reverse movement, thereby realizing image stabilization. The gyro sensor 180B can be further used in navigation scenarios and somatosensory games.

[00114] The barometric pressure sensor 180C is used to measure barometric pressure. In some embodiments, mobile phone 100 calculates altitude using the barometric pressure value measured by barometric pressure sensor 180C to provide positioning and navigation assistance.

In addition, a function such as automatic flip cover unlock is set based on the detected open/close state of the leather case or the open/close state of the flip cover.

[00116] The acceleration sensor 180E can detect the acceleration value of the mobile phone 100 in each direction (typically three axes). When the mobile phone 100 is stationary, the acceleration sensor 180E can detect the value and direction of gravity. The acceleration sensor 180E may be further configured to identify the position of the electronic device and is used in applications such as horizontal and vertical screen switching and pedometer.

[00117] The distance sensor 180F is configured to measure a distance. Mobile phone 100 can measure distance using infrared or laser light. In some embodiments, in a photography scenario, the mobile phone 100 may use the distance sensor 180F to measure the distance to realize fast focusing.

[00118] The ambient light sensor 180L is configured to sense the brightness of the ambient light.

[00120] The temperature sensor 180J is configured to detect temperature. In some embodiments, the mobile phone 100 executes the temperature policy using the temperature detected by the temperature sensor 180J. For example, when the temperature reported by the temperature sensor 180J exceeds a threshold value, the mobile phone 100 reduces the processor performance near the temperature sensor 180J to reduce power consumption and realize thermal protection. In some other embodiments, when the temperature is less than another threshold, the mobile phone 100 heats the battery 142 to avoid the low temperature crash of the mobile phone 100. In some other embodiments, when the temperature is less than another threshold, mobile phone 100 raises the output voltage of battery 142 to avoid a low temperature shutdown.

For example, a touch operation performed in different applications (such as photography and audio playback) may correspond to different vibration feedback effects. The motor 191 may also correspond to different vibration feedback effects when a touch operation is applied to different areas of the display 194. Different application scenarios (eg, time reminder, information reception, alarm clock, and game) may also correspond to different vibration feedback effects. Alternatively, the vibration feedback effect on touch can be customized.

[00126] It can be understood that the structure shown in this embodiment of this application is not a specific limitation for mobile phone 100. In some other embodiments of this application, mobile phone 100 may include more or fewer components than shown in the figure, or some components may be combined, or some components may be separated, or a different arrangement of components may be used. The components shown may be implemented in hardware, software, or a combination of software and hardware.

[00127] An electronic device software system may use a hierarchical architecture, an event-driven architecture, a microkernel architecture, a microservice architecture, or a cloud architecture. In this embodiment of this application, the Androyd system with a hierarchical architecture is used as an example to describe the software architecture of an electronic device.

[00128] Referring to FIG. 6, the software architecture of an electronic device may include a hardware layer, a driver layer, a hardware abstraction layer (HAL), an infrastructure layer, and an application layer.

[00129] The application layer may send a non-contact photosensitive application registration event to the infrastructure layer to require the infrastructure layer to enable the non-contact photosensitive function. The non-contact photosensitive function refers to a function of detecting, using a non-contact photosensitive sensor, that an obstacle is approaching or moving away from the touch screen, as described in the prior art. Although the non-contact photosensitive sensor may not be used in this embodiment of this application, but the touch screen is used to sense that an obstacle is approaching or moving away from the touch screen, for an application in the application layer, the non-contact photosensitive function can still be provided using the non-contact photosensitive event. registration. Of course, the name of the non-contact photosensitive event can also be changed, for example, changed to "non-contact detection event", as long as the function of detecting whether an obstacle approaches or moves away from the touch screen can be presented. In this embodiment of this application, this is not a limitation.

[00130] The acceleration data output by the acceleration sensor may be used to determine a gesture (eg, raise, lower, or roll over) of a user using a gesture algorithm in the infrastructure layer.

[00131] An integrated circuit (IC) of the touch screen can send raw data (a capacitance value generated at each contact position) generated when the touch screen senses an obstacle to the touch host processing daemon. , THP).

[00132] In this embodiment of this application, the determination of a gesture may include two stages of determination: a small gesture determination stage and a large gesture determination stage. The difference between the large gesture determination stage and the small gesture determination stage is the different sampling rate and different corresponding sampling time of the gesture algorithm, and the total number of sampling points corresponding to the small gesture determination stage is less than the total number of sampling points corresponding to the large gesture determination stage.

[00133] Small Gesture Determination Step: The gesture algorithm in the infrastructure layer determines, based on the acceleration data sampled by the acceleration sensor in the first period, whether the user's gesture is a given gesture (eg, up or down). If yes, the infrastructure layer runs the THP daemon in the hardware abstraction layer to execute the THP algorithm. The THP manager may input the capacitance data reported by the touch screen into the THP algorithm to obtain a calculation result (whether an obstacle is approaching or moving away from the touch screen) and generate an appropriate approach or distance event for the message based on the calculation result.

[00134] Large gesture determination step: In a process in which the THP manager executes the THP algorithm, the gesture algorithm in the infrastructure layer may continue to receive acceleration data reported by the acceleration sensor, and then determine based on the acceleration data obtained by sampling the acceleration sensor in third period, whether the user's gesture is a predetermined gesture (eg, up or down), wherein the third period is longer than the first period and the end time of the third period is later than the end time of the first period.

[00135] The THP algorithm of the THP program manager receives an event (e.g. zoom in or out) based on the user's gesture, a scenario recognition result (e.g. make a call or avoid false touch), capacitance data from the touch screen, and reports the event to the sensor manager. The capacitance data that is input to the THP algorithm may be capacitance data sensed by contacts in all areas of the touch screen, or may only be capacitance data sensed by contacts in the edge area of the touch screen (for example, capacitance data sensed by contacts in the first three rows, last three rows, three left columns, or three right columns on the touchscreen).

[00136] The sensor manager may send a switch control instruction to the THP manager. For example, the sensor manager may deliver an enable instruction based on a user gesture (small gesture) recognized by the gesture algorithm; and upon receiving the enable instruction delivered by the sensor manager, the THP driver initiates the THP daemon to execute the THP algorithm. The sensor manager may further deliver a deny instruction based on a proximity event sent by the THP manager, or deliver a deny instruction based on a user gesture (large gesture) recognized by the gesture algorithm so that the THP algorithm of the THP manager goes to sleep to reduce power consumption.

[00137] The THP algorithm and the gesture algorithm may be executed on a system on chip (SOC) application chip. In addition, to reduce power consumption, the gesture algorithm can be executed in the sensor hub chip (sensorhub) of the application chip.

[00138] This embodiment of this application may apply to scenarios such as making a call or calling a third party application (such as WeChat). For example, after detecting, based on a relatively small amount of acceleration data, that a gesture performed by a user on an electronic device is a lift, the processor begins to detect whether an obstacle is approaching the touch screen. Upon detecting that an obstacle is approaching the touch screen, the processor turns off the touch screen to reduce the power consumption of the electronic device, or upon detecting that an obstacle is approaching the touch screen and re-determining, based on additional acceleration data, that the gesture performed by the user on an electronic device is a lift, the processor disables the touch screen to reduce the power consumption of the electronic device. For example, upon detecting, based on a relatively small amount of acceleration data, that a gesture performed by a user on an electronic device is a drop, the processor begins to determine whether the obstacle is moving away from the touch screen. If it is detected that the obstacle is moving away from the touch screen, the touch screen is turned on to enable the user's operation, or if it is detected that the obstacle is moving away from the touch screen and re-determined, based on more acceleration data, that the gesture made by the user on the electronic device , is lowering, the touch screen is turned on to enable user operation.

[00139] This embodiment of this application can be further applied to a false touch prevention scenario. For example, an electronic device is put into a pocket, and the power-on key is incorrectly pressed due to a reason such as the user's movement, so that the touch screen turns on and starts detecting whether the distance between the obstacle and the touch screen is less than or equal to a predetermined value. If the distance between the obstacle and the touch screen is less than or equal to the set value, prompt information is displayed to remind the user that the obstacle is blocking the touch screen; or when it is detected that the distance between the obstacle and the touch screen is less than or equal to a predetermined value, and the position change of the electronic device after recognition based on the acceleration data has a periodic change rule, the touch screen can be considered to be touched incorrectly, and the screen is turned off to save power.

[00140] It should be understood that a software module and/or program corresponding to the software architecture of FIG. 6 may be stored in the internal memory 121 of the mobile phone 100 shown in FIG. 3.

[00141] The following describes in detail the technical solutions provided in the embodiments of this application using two specific embodiments. In the following embodiments, the technical solution used in the mobile phone 100 is used as an example.

Embodiment 1

[00142] FIG. 7 is a flowchart of a display control method according to an embodiment of this application. The method includes the following steps.

[00143] S701. When it is determined that the gesture performed by the user on the mobile phone is the predetermined gesture, the capacitance measurement value in the predetermined area of the touch screen is obtained.

[00144] In particular, when the processor requests, using the non-contact photosensitive registration event of the application in the application layer (for example, the non-contact photosensitive registration event when WeChat starts the call process), the infrastructure layer to enable the non-contact photosensitive function, the infrastructure layer starts the execution of the gesture algorithm. The acceleration sensor in the hardware layer reports the captured acceleration data to the infrastructure layer, and the gesture algorithm in the infrastructure layer calculates based on the acceleration data that the gesture performed by the user on the mobile phone is a predetermined gesture. A given gesture can be up, down, or flip.

[00145] Referring to FIG. 8, the gesture algorithm may include three defining logics: (1) relative mobility. Once the direction of acceleration and any of the three axes of the spatial coordinate system (i.e., x-axes, y-axes, and z-axes) intersect, the gesture of the mobile phone is considered to change, and a gesture such as up, down, or flip can occur. This logic does not distinguish between rising and falling, but only between stationary and moving states. (2) Monotonicity. When the acceleration data at a certain number of sampling points increase or decrease monotonically, it can be determined that a gesture such as raising, lowering, or flipping can occur. The gesture algorithm can filter out, using this logic, the influence of some harsh noise on the accuracy of the gesture definition. (3) Non-periodicity. Determine the number of peaks and valleys in the acceleration data. If the number of peaks and troughs is less than a specific value, it is considered that a lifting gesture may occur; otherwise, it is determined that the mobile phone moves periodically, for example, if the user runs at a constant speed, the mobile phone shakes periodically, and the number of peaks and valleys is relatively large. This logic can reduce the frequency of false touches. The processor determines that the given gesture occurs only when it is determined that all three of the above-described determination logics are satisfied.

[00146] In addition, when the gesture performed by the user on the mobile phone is one of raising, lowering, or flipping, the sensor manager in the infrastructure layer may send an enabling instruction to the THP manager, and the THP manager may input the capacitance measurement value reported by the sensor. screen, to the THP algorithm to obtain the calculation result (whether the obstacle is approaching or moving away from the touch screen) and generating, based on the calculation result, the corresponding approach event or distance event for the message.

[00147] The capacitance measurement value that is input to the THP algorithm is the capacitance measurement value in the predetermined area of the touch screen. The predetermined area may be an area which is on the touch screen and in which the capacitance measurement value is less affected by the deformation of the metal sheet. For example, the contacts on the touch screen form a contacts array, and the specified area can be the contact area formed by the first three rows in the contacts array, the contact area formed by the last three rows in the contacts array, the contact area formed by the left three columns in the contacts array, the contact area , formed by the three right columns in the contacts array, or similar. In this embodiment of the present application, this is not particularly limited. In a possible example with reference to FIG. 9, the predetermined area includes the contact area formed by the first to third rows, the contact area formed by the left three columns in the fourth to tenth rows, and the contact area formed by the right three columns in the fourth to tenth rows.

[00148] The capacitance measurement value may be the capacitance measurement value in the set period. For example, the set period may refer to a given number of frames, for example, a measurement value of the capacity of five consecutive frames in a given area of the touch screen is obtained.

[00149] S702. When it is determined that the capacitance measurement value satisfies the first predetermined condition, switching of the touch screen display state is controlled, the switching including switching the display state from an on screen to an off screen or from an off screen to an on screen.

[00150] In particular, upon receiving an approach or distance event reported by the THP manager, the infrastructure layer in the processor starts the screen off or screen on procedure and indicates to the driver layer to perform the screen off or screen on procedure. If the event is a proximity event, the screen-off routine is triggered; or if the event is a distance event, the screen-on procedure is started.

[00151] In this embodiment of this application, the THP control program may determine the trend of change (ie approach or distance) of the distance between the obstacle and the touch screen based on the trend of the capacitance measurement value. For example, when the distance between the obstacle and the touch screen becomes smaller (that is, approaching is performed), the contact capacitance measurement value at which the touch screen is close to the obstacle increases; or when the distance between the obstacle and the capacitive touch screen becomes larger (ie, moving away), the contact capacitance measurement value at which the touch screen is close to the obstacle decreases.

[00152] The first predetermined condition corresponding to the scenario in which the obstacle is approaching the touch screen may be different from the first predetermined condition corresponding to the scenario in which the obstacle is moving away from the touch screen. Specifically, in a scenario in which an obstacle approaches the touch screen, the first predetermined condition may include the following: The capacitance measurement value in the predetermined area of the touch screen satisfies a monotonically increasing trend in the first period, and the capacitance measurement value at the time of the end of the first period is greater than the first a given threshold value; and in the scenario where the obstacle moves away from the touch screen, the first predetermined condition may include the following: The capacitance measurement value in the predetermined area of the touch screen satisfies a monotonically decreasing trend in the first period, and the capacitance measurement value at the end time of the first period is less than the second predetermined threshold values. The second predetermined threshold is less than the first predetermined threshold.

[00153] Optionally, after the infrastructure layer initiates a screen off or screen on procedure, the sensor manager in the infrastructure layer can further deliver a disable instruction so that the THP daemon's THP algorithm goes to sleep to reduce power consumption.

[00154] It should be noted that the touch screen of the mobile phone in this embodiment may be the touch screen shown in FIG. 3, or may be the touch screen shown in FIG. 4. In this embodiment of this application, this is not a limitation.

[00155] In an optional implementation, the THP algorithm is implemented in the infrastructure layer. Therefore, to reduce power consumption, when the touch screen approaches an obstacle, the touch screen may not turn off, but enter a low power mode. In this case, the THP algorithm is disabled. The mobile phone only exits low power mode when it is activated by a gesture (eg, the user lowers or flips the mobile phone). In this case, the mobile phone wakes up the THP algorithm (ie, the sensor manager in the infrastructure layer sends an enable instruction to the THP manager).

[00156] In this embodiment, the processor selects an area (i.e., the above specified area) that is on the touch screen and that corresponds to a metal plate that is not subject to deformation to generate a capacitance measurement value to detect whether an obstacle is approaching towards or away from the touch screen. Since the capacitance value corresponding to this region may be less influenced, the result of the calculation (i.e. approach or distance) is more accurate than the result (i.e. approach or distance) obtained by calculating based on the capacitance value of the entire screen, so that the non-contact detection accuracy of the electronic device can be improved and the display state of the electronic device can be controlled more precisely.

Embodiment 2

[00157] FIG. 10 is a flowchart of another display control method according to an embodiment of this application. The method includes the following steps.

[00158] S1001. Determining, based on the first acceleration data, whether the gesture performed by the user on the mobile phone is a given gesture, wherein the first acceleration data is the acceleration data captured by the acceleration sensor in the first period, and the sampling rate of the acceleration data is the first frequency.

[00159] In particular, when the processor requests, using the non-contact photosensitive registration event of the application in the application layer (for example, the non-contact photosensitive registration event when WeChat starts the call process), the infrastructure layer to enable the non-contact photosensitive function, the infrastructure layer starts the execution of the gesture algorithm. After receiving the acceleration data which is collected in the first period and reported by the acceleration sensor in the hardware layer, the infrastructure layer calculates, using the gesture algorithm, that the gesture performed by the user on the mobile phone is the predetermined gesture, that is, the small gesture described above. For the small gesture defining logic of the gesture algorithm, refer to the defining logic of the gesture algorithm in Embodiment 1. The details are not repeated here.

[00160] S1002. When it is determined that the gesture performed by the user on the mobile phone is the predetermined gesture, the touch screen capacitance measurement value in the second period is obtained, and it is determined whether the capacitance measurement value satisfies the second predetermined condition.

[00161] In particular, after the processor determines, using the infrastructure layer, that the gesture performed by the user on the mobile phone is a given gesture, the sensor manager in the infrastructure layer may send an enabling instruction to the THP daemon, and the THP daemon may enter the measurement value capacitance captured by the touch screen in the second period into the THP algorithm to obtain the calculation result (whether the obstacle is approaching or receding) and generating, based on the calculation result, the corresponding approach or distance event for the message. For a specific implementation of the THP algorithm, refer to the specific implementation of the THP algorithm in the embodiments. The details are not repeated here. For a specific implementation of a given gesture, refer to a specific implementation of a given gesture in Embodiment 1. The details are not repeated here.

[00162] The start time of the second period may be the end time of the first period, or the start time of the second period may be later than the end time of the first period.

[00163] The touch screen capacitance measurement value in the second period may be a capacitance measurement value detected by contacts on the entire touch screen, or may be a capacitance measurement value detected in some areas of the touch screen. In this embodiment of the present application, this is not particularly limited. For example, the capacitance measurement value may be a capacitance measurement value detected in the predetermined area shown in FIG. 9.

[00164] It should be noted that the second predetermined condition here may be the same as or different from the first predetermined condition in Embodiment 1. In this embodiment of this application, this is not a limitation. For the case in which the second predetermined condition is the same as the first predetermined condition in Embodiment 1, refer to the specific implementation of the first predetermined condition in Embodiment 1. The details are not repeated here. The following are examples based on various cases: In a scenario in which an obstacle approaches the touch screen, the second predetermined condition may include the following: The capacitance measurement value satisfies a monotonically increasing trend in the second period, and the capacitance measurement value at the time of the end of the second period does not exceeds the first predetermined threshold value; and in a scenario in which the obstacle moves away from the touch screen, the second predetermined condition may include: The capacitance measurement value satisfies a monotonically decreasing trend in the second period, and the capacitance measurement value at the end time of the second period is not less than the second predetermined threshold value. The second predetermined threshold is less than the first predetermined threshold.

[00165] S1003. When it is determined that the capacitance measurement value satisfies the second predetermined condition, it is re-determined, based on the second acceleration data, whether the gesture performed by the user on the mobile phone is the predetermined gesture, the second acceleration data being the acceleration data captured by the acceleration sensor in the third period, the sampling rate of the acceleration data is the second frequency, and the duration of the third period is greater than the duration of the first period and/or the first frequency is less than the second frequency.

[00166] In particular, after receiving the approach or distance event reported by the THP process, the infrastructure layer continues to execute the gesture algorithm. The gesture algorithm re-determines, based on the second acceleration data reported by the acceleration sensor, whether the user's gesture is a predetermined gesture, i. e. the above stage of determining a large gesture. For the large gesture defining logic, refer to the gesture algorithm defining logic in Embodiment 1. The details are not repeated here. The start time of the third period may be the start time of the first period. Of course, the start time of the third period may alternatively be later than the start time of the first period. In this document, this is not a limitation.

[00167] In this embodiment of this application, the condition "the duration of the third period is greater than the duration of the first period and/or the first frequency is less than the second frequency" is set to ensure that the data amount (total number of sampling points) of the second acceleration data is larger than the data amount (total number of sampling points) of the first acceleration data, i.e. to ensure that the large gesture detection accuracy is greater than the small gesture detection accuracy, thereby further ensuring non-contact detection accuracy. That is, if the duration of the third period does not exceed the duration of the first period, the first frequency must be less than the second frequency; if the duration of the third period is longer than the duration of the first period, the first frequency may be less than or equal to the second frequency, but it is required to ensure that the amount of the second acceleration data collected in the third period is greater than the amount of the first acceleration data collected in the first period. Optionally, the first period may be a sub-period in the third period, ie, the second acceleration data may include the first acceleration data.

[00168] In this embodiment of the present application, the first acceleration data corresponding to a small gesture and the second acceleration data corresponding to a large gesture differ depending on the requirement of the scenario. In particular, it is required that the first acceleration data corresponding to a small gesture cannot be misreported, and the first acceleration data should not be missed. For example, if the sampling rate of the acceleration sensor in the first period is 100 Hz, and there are 10 sampling points in total, the sum of the sampling time of the first acceleration data and the small gesture detection time is approximately 230 ms. It is required that the second acceleration data corresponding to the large gesture cannot be missed (ie, more data is required), and the second acceleration data should not be misreported. For example, if the sampling rate of the acceleration sensor is also 100 Hz in the third period, and there are 20 sampling points in total, the sum of the sampling time of the second acceleration data and the large gesture detection time is 400 ms.

[00169] S1004. When it is re-determined that the gesture performed by the user on the mobile phone is a predetermined gesture, the switching of the touch screen display state is controlled, the switching including switching the display state from an on screen to an off screen or from an off screen to an on screen.

[00170] In particular, after the infrastructure layer re-determines, by executing the gesture algorithm, that the gesture performed by the user on the mobile phone is a given gesture, the infrastructure layer starts the screen off or screen on procedure and instructs the driver layer to perform the procedure. turn off the screen or turn on the screen.

[00171] Optionally, after the infrastructure layer initiates a screen off or screen on procedure, the sensor manager in the infrastructure layer can further deliver a disable instruction such that the THP daemon's THP algorithm goes to sleep to reduce power consumption.

[00172] It should be noted that the touch screen of the mobile phone in this embodiment may be the touch screen shown in FIG. 3, or may be the touch screen shown in FIG. 4. In this embodiment of this application, this is not a limitation.

[00173] For example, FIG. 11 is a schematic representation of the time it takes to turn on the touch screen when an obstacle moves away from the touch screen (ie, the distance between the obstacle and the touch screen increases) in a call or third-party application call scenario. The processor runs the gesture algorithm in the infrastructure layer. The gesture algorithm first determines, based on the first acceleration data reported by the acceleration sensor, that the user's gesture is to move down (in the small gesture detection stage, the time from picking up the acceleration data to outputting the result of the gesture detection is approximately 230ms), and sends the gesture to the hardware abstraction layer using the driver layer, and the THP control program in the hardware abstraction layer runs the THP algorithm. In the THP algorithm, the THP control program receives the capacitance measurement value, which consists of five consecutive frames, and which is reported by the touch screen, and determines the distance between the obstacle and the touch screen based on the capacitance measurement value. As the distance increases, the THP control program determines that the obstacle is moving away from the touch screen. After the distance between the obstacle and the touch screen exceeds the set value, the THP control program reports a distance event to the infrastructure layer using the driver layer. The infrastructure layer continues to execute the gesture algorithm, and the gesture algorithm re-determines, based on the second acceleration data reported by the acceleration sensor, that the user's gesture is a downstroke (in the large gesture determination stage, the time from the acceleration data acquisition to the output of the gesture determination result is about 400 ms) . The infrastructure layer starts the screen-on procedure and tells the driver layer to perform the screen-on procedure. The infrastructure layer delivers the backlight instruction to the driver layer to enable the touch screen.

[00174] Similarly, the THP algorithm is implemented in the infrastructure layer. Therefore, to reduce power consumption, when the touch screen approaches an obstacle, the touch screen may not turn off, but enter a low power mode. In this case, the THP algorithm is disabled. The mobile phone only exits low power mode when it is activated by a gesture (eg, the user lowers or flips the mobile phone). In this case, the THP algorithm wakes up (ie, the sensor manager in the infrastructure layer sends an enable instruction to the THP manager) and the method described above is executed in this embodiment of this application.

[00175] For example, referring to FIG. 12A-FIG. 12B, after the touch screen is close to an obstacle, the touch screen can enter the low power mode without turning off the power. In low power mode, the touch screen is turned off and the THP algorithm is disabled. If activation by a small gesture is detected (for example, it is recognized based on acceleration data in a relatively short period that the user performs a gesture such as lowering a mobile phone or turning over a mobile phone), the touch screen exits the low power mode, and the THP algorithm wakes up; otherwise, the touch screen remains in low power mode and is still turned off. After the THP algorithm wakes up, the touch screen capacitance measurement value in the second period is obtained, and it is determined whether the capacitance measurement value in the predetermined period follows a monotonically decreasing trend. If so, it is further determined whether the capacitance measurement value at the end time of the predetermined period is less than the second predetermined threshold value; otherwise, it is additionally determined that the screen is still off. If the capacitance measurement value at the end time is less than the second predetermined threshold value, the touch screen is turned on; otherwise, the touch screen continues to determine whether the activation condition is satisfied with a large gesture (for example, it is recognized based on the acceleration data for a relatively long period that the user performs a gesture such as lowering the mobile phone or flipping the mobile phone). If the large gesture activation condition is satisfied, the touch screen is enabled; otherwise, the screen is still off.

[00176] In this embodiment, after determining by calculation based on the capacitance measurement value detected by the touch screen that the distance ratio between the obstacle and the mobile phone satisfies the second predetermined condition, a large gesture determination step is added: determination based on the position change of the electronic device is whether an event in which an obstacle approaches or moves away from an electronic device occurs by chance; and after determining that the event does not occur by chance, which is equivalent to determining that the user has an intention to move the electronic device closer to or further away from the human body, turning off/on the screen. Thus, even if the capacitance value sensed by the touch screen is affected by the environment, this gesture determination step guarantees the accuracy of controlling the display of the electronic device, so that the user experience is improved.

[00177] With reference to the above embodiments and the corresponding accompanying drawings, an embodiment of this application further provides a display control method, and this method can be implemented in an electronic device (such as a mobile phone or tablet computer) having a touch screen.

[00179] S1302. When the received capacitance measurement value satisfies the first predetermined condition, the touch screen display state switching control.

[00182] S1402. When the obtained capacitance measurement value satisfies the second predetermined condition, it is re-determined, based on the second acceleration data, whether the user's gesture of moving the electronic device is the predetermined gesture, the second acceleration data being the acceleration data that pertains to the electronic device in the third period, and which are captured based on the second sampling rate, and the duration of the third period is greater than the duration of the first period and/or the first sampling rate is less than the second sampling rate.

[00183] S1403. When it is re-determined that the user's gesture for moving the electronic device is said predetermined gesture, the touch screen display state switching control.
