The embodiment of the application provides electronic equipment. The electronic device can be a smart phone, a tablet computer and the like. Referring to fig. 1, the electronic device 100 includes a cover plate 10, a display screen 21, a circuit board 30, and a case 40.

Wherein the cover plate 10 is mounted to the display screen 21 to cover the display screen 21. The cover plate 10 may be a transparent glass cover plate. In some embodiments, the cover plate 10 may be a glass cover plate made of a material such as sapphire.

The display screen 21 is mounted on the housing 40 to form a display surface of the electronic apparatus 100. The display 21 serves as a front case of the electronic device 100, and forms a closed space with the housing 40 for accommodating other electronic components of the electronic device 100. Meanwhile, the display screen 21 forms a display surface of the electronic apparatus 100 for displaying information such as images, texts, and the like.

In some embodiments, the display screen 20 may be displayed full screen. That is, the display screen 20 includes only display regions and does not include non-display regions, as shown in FIG. 2.

The circuit board 30 is mounted inside the housing 40 to accommodate the circuit board 30 in the closed space. The circuit board 30 may be a motherboard of the electronic device 100. The circuit board 30 is provided with a grounding point to realize grounding of the circuit board 30. Functional components such as a camera, a processor, and a sensor may be integrated on the circuit board 30. Meanwhile, the display screen 21 may be electrically connected to the circuit board 30.

In some embodiments, display control circuitry is disposed on the circuit board 30. The display control circuit outputs an electric signal to the display screen 21 to control the display screen 21 to display information.

The housing 40 is used to form the outer contour of the electronic device 100. The housing 40 may be made of plastic or metal. The housing 40 may be integrally formed.

In some embodiments, as shown in FIG. 3, the sensor assembly 22 is disposed on a circuit board 30. Wherein the sensor assembly 22 is located on one side of the display screen 21.

It will be appreciated that the sensor assembly 23 is disposed on the inside of the display screen 21. Here, the inner side refers to a side where the display screen 21 is not visible when viewed from the outside of the electronic apparatus 100. That is, the sensor assembly 22 is located inside the electronic device 100.

The sensor assembly 22 may include a signal transmitter 221 and a signal receiver 222, among other things. The signal transmitter 221 transmits a detection signal a outwards according to a signal transmission frequency interval thereof, the detection signal a is transmitted to the outside through the display screen 21, and the detection signal a generates a reflection signal B after passing through an external object 200 (e.g., a user's face). The reflected signal B passes through the display screen 21 and enters the signal receiver 222. Wherein, the signal emission frequency can be set according to the time requirement.

In order to facilitate the electronic device 100 to determine the approaching or the departing, the signal receiver 222 may record a receiving time each time the probe signal is received.

In some embodiments, referring to fig. 4, the signal transmission reference clocks (for example, pulse signals) of the signal transmitter 221 are T, and in fig. 3, the signal transmitter 221 sends out a detection signal when the rising edge of each pulse arrives.

In some embodiments, the distance between the signal transmitter 221 and the signal receiver 222 is between 2 mm and 14 mm, and experiments have shown that the distance range can have better proximity sensing effect and high accuracy.

In some embodiments, the distance between the signal transmitter 221 and the signal receiver 222 may include: the distance between the geometric center of the signal transmitter 221 and the geometric center of the signal receiver 222. The signal transmitter 221 and the signal receiver 222 are spaced from each other, so that the isolation between the signal transmitter 221 and the signal receiver 222 can be improved, and the influence of the signal transmitted by the signal transmitter 221 on the signal receiver 222 can be reduced.

In some embodiments, referring to fig. 5, the signal transmitter 221 and the signal receiver 222 are packaged into the first chip 24.

In some embodiments, the signal emitter 221 is an infrared emitter for emitting infrared rays. The signal receiver 222 is an infrared receiver for receiving infrared rays.

In some embodiments, the Display 21 may be a Liquid Crystal Display (LCD) or Organic Light-Emitting Diode (OLED) Display, or the like. When the display screen 21 is a liquid crystal display screen, the display screen 21 may include a backlight plate, a lower polarizer, an array substrate, a liquid crystal layer, a color film substrate, an upper polarizer, and the like, which are sequentially stacked. When the display panel 21 is an organic light emitting diode display panel, the display panel 21 may include a base layer, an anode, an organic layer, a conductive layer, an emission layer, a cathode, and the like, which are sequentially stacked.

In some embodiments, referring to fig. 6, the sensor assembly 22 may further include an ambient light sensor 223, the ambient light sensor 223 for sensing an ambient light signal. It is understood that the ambient light sensor 223 is disposed inside the display screen 21 along with the signal transmitter 221 and the signal receiver 222.

The ambient light sensor 223 is used for sensing an ambient light signal transmitted through the display screen 21 and transmitting the sensing information, such as the intensity of the ambient light, to the processor of the electronic device 100, and the processor controls the brightness of the display screen 21 according to the sensing information.

For example, when the ambient light sensor 223 detects that the ambient light signal becomes weak, the processor may increase the brightness of the display screen 21, and when the ambient light sensor 223 detects that the ambient light signal becomes strong, the processor may decrease the brightness of the display screen 21.

In some embodiments, the signal transmitter 221, the signal receiver 222, and the ambient light sensor 223 are spaced apart from one another. The distance between the signal transmitter 221 and the signal receiver 222 is between 2 and 14 millimeters. It is understood that the above distance is a distance between a geometric center of the signal transmitter 221 and a geometric center of the signal receiver 222. The signal emitter 221, the signal receiver 222 and the ambient light sensor 223 are spaced from each other, so that the isolation among the signal emitter 221, the signal receiver 222 and the ambient light sensor 223 can be improved, and the influence of the signal emitted by the signal emitter 221 on the signal receiver 222 and the ambient light sensor 233 can be reduced.

In some embodiments, to reduce interference or impact of the signal emitted by the signal emitter 221 on the ambient light sensor 233, the distance between the ambient light sensor 223 and the signal receiver 222 may be greater than the distance between the signal emitter 221 and the signal receiver 222. It is understood that the distance between the ambient light sensor 223 and the signal receiver 222 is the distance between the geometric center of the ambient light sensor 223 and the geometric center of the signal receiver 222.

In some embodiments, referring to fig. 7, the signal transmitter 221, the signal receiver 222, and the ambient light sensor 223 are packaged into a second chip 25.

In some embodiments, referring to fig. 8, a light shielding layer 210 is disposed on a side of the display screen 21 facing the sensor assembly 22, and a corresponding opening 213 is disposed on the light shielding layer 210 for the signal emitter 221. The opening 213 allows light signals, sound wave signals, and the like to pass through.

Wherein, the signal transmitter 221 is configured to transmit the probing signal a outwards. The detection signal a is transmitted to the outside through the opening 213 and the display screen 21. When the detection signal a contacts an external object 200 (e.g., a user's face), a reflected signal B is generated. The reflected signal B enters the signal receiver 222 through the display screen 21.

In some embodiments, the opening 213 is a circular hole. The diameter of the opening 213 is 2 to 4 mm. In other embodiments, the opening 213 may be a square hole, an elliptical hole, or other shapes.

The embodiment of the application provides a display screen control method which is suitable for electronic equipment. The electronic equipment comprises the electronic equipment provided by any embodiment of the application. The display screen control method controls the state of the display screen according to the distance state between the electronic equipment and the external object. The distance state includes a distant state and a close state. The status of the display screen includes on and off. The display control method is explained below.

In some embodiments, a display screen control method is further provided, and with reference to fig. 9, a specific flow of the method is as follows:

s501, acquiring a time interval between two adjacent detection signal receptions of the signal receiver in a preset time period to obtain a time interval set.

The preset time period may be set according to actual requirements, for example, 20s, 30s, and the like.

The time interval set includes a plurality of time intervals, and the time interval may be a time difference between two adjacent received sounding signals of adjacent signal receivers.

Since the signal transmitter can transmit the detection signal at regular intervals, the signal receiver can receive the detection signal transmitted by the signal transmitter multiple times. The embodiment of the application can acquire the time interval between two adjacent signal receiving times and the detection signal, and then analyzes the time interval to determine the motion state of the electronic equipment relative to the external object.

In some embodiments, a receiving time at which the signal receiver receives the sounding signal within a preset time period may be obtained, and then, a time interval between two adjacent times of receiving the sounding signal by the signal receiver within the preset time period may be obtained according to the receiving time.

For example, referring to fig. 10, within a preset time period t, the receiving time of the signal receiver receiving the probe signal for the 1 st time includes t1, the receiving time of the probe signal for the 2 nd time includes t2, and the receiving time of the probe signal for the 3 rd time includes t3 … … tn, where n is a positive integer greater than 3.

In this case, the interval between the 1 st and 2 nd received probe signals is t21-t 2-t1, the interval between the 2 nd and 3 rd received probe signals is t32-t 3-t2, and … … the interval between the i-1 st and i-th received probe signals is ti (i-1) -ti-t (i-1) … ….

In some embodiments, in order to improve the accuracy of the display screen state control and save resources, the display screen state control may be performed only when the receiving time reaches a certain number, that is, the receiving frequency reaches a certain value. For example, the step of "acquiring a time interval between two adjacent times of receiving the sounding signal by the signal receiver within the preset time period" may include:

acquiring the receiving times of the detection signals received by the signal receiver in a preset time period;

and when the receiving times are more than the preset number, acquiring the time interval of the adjacent two times of receiving the detection signals by the signal receiver in the preset time period.

For example, the number of times that the signal receiver receives the detection signal in the preset time period is c, and if c is greater than the preset number f, the number of available time intervals is large, that is, the time data is comprehensive, and the accuracy of controlling the display screen based on the time intervals obtained by the scene at this time is high. If c is not larger than the preset number f, the number of the time intervals available for the current electronic equipment is small, namely the time data is incomplete and cannot reflect the motion state of the electronic equipment, and the accuracy of controlling the display screen based on the time intervals obtained by the scene at the moment is low.

In some embodiments, when the number of times of reception is not greater than the preset number, in order to ensure the success rate and accuracy of the display screen control, the enlarged preset time period is obtained, and the reception of the signal received by the signal receiver within the enlarged preset time period is obtained again.

For example, the original preset time period is 5s, and at this time, the preset time period may be expanded to 10s, and so on. Then, the number of signal receptions within 10s is acquired.

S502, obtaining the change information of the time interval in the time interval set.

For example, the time intervals in the time interval set may be analyzed to obtain the variation information of the time intervals.

The change information of the time interval may be change rule information of the aggregate time interval, and may include, for example, an increment of the time interval, a decrement of the time interval, a discrete change of the time interval, and the like.

In some embodiments, the time intervals in the set may be compared one by one in sequence, and variation information of the time intervals is obtained based on the comparison result.

And S503, determining the motion state of the electronic equipment relative to the external object according to the change information, wherein the motion state comprises a close state or a far state.

The external object may include a face of the user or an object other than the electronic device.

The approaching state may be a movement in which the electronic device gradually approaches to the external object (i.e., the distance between the electronic device and the external object gradually decreases).

The distant state may be a movement in which the electronic device is more and more distant from the external object (i.e., the distance between the electronic device and the external object is gradually increased).

In practical situations, if the position of the electronic device relative to an external object (such as the face of the user) changes, the time interval during which the signal receiver receives the detection signal also changes accordingly.

For example, when the electronic device is in a close state relative to the motion state of an external object (e.g., the face of the user), the time interval between the signal receiver receiving the detection signal is gradually shortened or reduced because the electronic device is closer to the external object and the time required for signal transmission is smaller.

For another example, when the electronic device is in a remote state with respect to the moving state of the external object (e.g., the face of the user), the time interval for the signal receiver to receive the detection signal will gradually increase as the electronic device is further away from the external object and the time required for signal transmission is further increased.

Therefore, the change of the time interval of the information receiver receiving the detection signal can reflect the motion state of the electronic equipment relative to the external object. Therefore, the embodiment of the application can analyze the time interval to obtain the change information of the time interval, and then determine whether the motion state of the electronic equipment relative to the external object is the close state or the far state based on the change information.

In some embodiments, when the change information includes an increment of the time interval, the operation state of the electronic device with respect to the external object is determined to be a distant state.

When the time interval is increased, which indicates that the reflection time of the detection signal is gradually increased, the distance between the electronic device and the external object may be increased, and at this time, it may be determined that the electronic device is being away from the external object.

For example, when t10 < t21 < t32 … … < ti (i-1), the motion state of the electronic apparatus with respect to the external object may be determined to be a distant state.

In some embodiments, when the change information includes a time interval decreasing, the operation state of the electronic device with respect to the external object is determined to be a proximity state.

When the time interval decreases, it indicates that the reflection time of the detection signal gradually decreases, and the distance between the electronic device and the external object may become smaller and smaller, and at this time, it may be determined that the electronic device is approaching the external object.

For example, when t10 > t21 > t32 … … > ti (i-1), the motion state of the electronic apparatus with respect to the external object may be determined to be a proximity state.

In consideration of the fact that in practical application, when the electronic device is far away from an external object, that is, the distance between the electronic device and the external object gradually increases, if the degree of the distance, that is, the magnitude of the increase in the distance is small, it indicates that the user does not want to watch the electronic device, and at this time, the state of the display screen does not need to be controlled. For example, when a user adjusts the positions of the phone and the ears of the user during phone call, the electronic device may be away from the external object, and at this time, the state of the display screen does not need to be controlled, such as being bright.

Therefore, in some embodiments, to accurately determine the motion state of the electronic device relative to the external object and avoid misoperation, the time interval increment can be combined to determine whether the electronic device is far away from the external object. That is, the step "determining that the operation state of the electronic device with respect to the external object is the distant state when the change information includes the time interval increment" includes:

when the change information comprises time interval increment, acquiring increment of each increment of the time interval to obtain a plurality of increments;

acquiring a target increment which is larger than a first preset threshold value from a plurality of increments;

and when the number of the target increment is larger than the preset number, determining that the running state of the electronic equipment relative to the external object is a far state.

Wherein the increment of the time interval is the increment of the current time interval relative to the previous time interval.

For example, the time interval t10 > t21 > t32 … … > ti (i-1), i.e., the time interval is increased in increments, and the increment Δ t0 of t10 is t10-0, the increment Δ t1 of t21 is t21-t10, the increment Δ t2 of t32 is t32-t21 … …, and Δ ti is ti (i-1) -t (i-1) (i-2) are obtained.

When a preset number, such as a incremental change, of Δ t0, Δ t1, Δ t2, and Δ t3 … … Δ ti (i-1) is greater than a first preset threshold Δ t ', it indicates that the electronic device is far away from an external object, such as a user's face, and it may be determined that the electronic device is in a far state. It is possible to determine that the operation state of the electronic apparatus with respect to the external object is a distant state.

Wherein a is a positive integer, which can be set according to actual requirements, and also the first preset threshold Δ t' can be set according to time requirements.

In consideration of the fact that in practical application, when the electronic device approaches to an external object, that is, the distance between the electronic device and the external object gradually decreases, if the degree of the approach, that is, the magnitude of the decrease in the distance is small, it indicates that the user does not want to approach the electronic device to the external object, and at this time, the display screen state does not need to be controlled. For example, when a user wants to view incoming call display contents, such as an incoming call number, more closely, at this time, the user may approach the electronic device to the eyes, and the electronic device may also approach an external object.

Therefore, in some embodiments, to accurately determine the motion state of the electronic device relative to the external object and avoid misoperation, the time interval increment can be combined to determine whether the electronic device is close to the external object. That is, the step "determining that the operation state of the electronic device with respect to the external object is the proximity state when the change information includes the time interval decrement" includes:

when the change information comprises time interval decrement, acquiring decrement of each time of the time interval decrement to obtain a plurality of decrement;

acquiring a target decrement larger than a second preset threshold value from the plurality of decrement;

when the number of the target decrement amounts is greater than the preset number, it is determined that the operation state of the electronic apparatus with respect to the external object is a distant state.

Wherein the decrement of the time interval decrement is the decrement of the current time interval relative to the previous time interval.

For example, the time interval t10 < t12 < t21 < t32 … … < ti (i-1), i.e., the time interval is decreased, the decreasing amount Δ t0 of t10 is t10-0, the decreasing amount Δ t1 of t21 is t21-t10, the decreasing amount Δ t2 of t32 is t32-t21 … …, and Δ ti is ti (i-1) -t (i-1) (i-2).

When the preset number, for example, b decreasing amounts, of Δ t0, Δ t1, Δ t2, and Δ t3 … … Δ ti (i-1) is greater than the second preset threshold Δ t ″, it indicates that the electronic device is approaching to an external object, for example, the face of the user, and at this time, it may be determined that the electronic device is in an approaching state. It is possible to determine that the operation state of the electronic apparatus with respect to the external object is a distant state.

Wherein b is a positive integer, which can be set according to actual requirements, and the second preset threshold Δ t ″ can also be set according to time requirements.

And S504, controlling the state of the display screen according to the motion state.

In some embodiments, the state of the display screen may be controlled based on the state of motion and the current state of the display screen.

For example, in some embodiments, when the display screen is in the screen-off state and the motion state is the far-away state, the display screen is controlled to be on;

and when the display screen is in a bright screen state and the motion state is in a close state, controlling the display screen to be off.

The current display screen control scheme generally determines approaching or departing based on the strength of a signal received by a signal receiver, however, when a proximity sensor is located below a display screen, the penetration capability of a detection signal is weakened due to obstruction of the display screen, the strength of the signal received by the signal receiver of the proximity sensor is weak, approaching or departing cannot be accurately determined, and accurate control over the state of the display screen is reduced.

However, as can be seen from the above, the embodiment of the present application may analyze a time interval change of the signal receiver receiving the detection signal, and determine whether the electronic device is close to or far away from the external object based on the time interval change, because the display screen may weaken the signal strength, and may not affect the time too much, the scheme may accurately determine the motion state of the electronic device relative to the external object, thereby improving the accuracy of the state control of the display screen.

In some embodiments, based on the above description of the method, another display screen control method is further provided, as shown in fig. 11, and the specific flow of the method is as follows:

s601, the electronic equipment acquires the receiving time and the receiving times of the detection signal received by the signal receiver in a preset time period.

S602, when the receiving times are larger than the preset number, the electronic equipment obtains the time interval of the signal receiver receiving the detection signals twice in the preset time period according to the receiving time to obtain a time interval set.
