the embodiment of the disclosure discloses a terminal, which comprises a touch screen and a distance sensing module, wherein the distance sensing module is positioned below the touch screen; detecting whether a target object exists in a preset distance of the touch screen or not by transmitting ranging signals through N distance sensors contained in a distance sensing module; the distance measurement signal emitted by the distance sensor can penetrate through the touch screen, and N is a positive integer greater than or equal to 2. In this way, in this embodiment, the distance sensor capable of transmitting the test signal penetrating the touch screen replaces the infrared distance sensor disposed at the top of the touch screen in the related art, and since the distance sensor is capable of transmitting the ranging signal penetrating the touch screen, for example, the ultrasonic signal of the ultrasonic sensor penetrates the liquid and has a strong fixed penetrating ability, the touch screen does not need to be perforated, so that the integrity of the touch screen is better, and a larger screen occupation ratio is realized. Meanwhile, whether the sensing object in the preset distance of the touch screen is a target object or not can be judged more accurately through the plurality of distance sensors, and whether shielding exists or not can not be judged only initially, so that misoperation phenomena of the touch screen for shielding are reduced for subsequent control of different scenes based on the target object. For example, the display state of the touch screen is maintained when the sensing object is a target object, and the display state of the touch screen is not maintained when the sensing object is not a target object, but the touch screen is controlled to enter a black screen state or a screen locking state as long as the sensing object is shielded.
It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the disclosure.

Detailed Description
Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the invention. Rather, they are merely examples of apparatus and methods consistent with aspects of the invention as detailed in the accompanying claims.
Fig. 1 is a schematic diagram of a terminal according to an exemplary embodiment, and as shown in fig. 1, the terminal 1 includes:
a touch screen 10;
the distance sensor module 11 includes: n distance sensors 110, located below the touch screen 10, for detecting whether there is a target object within a preset distance of the touch screen 10 by transmitting a ranging signal; the distance measurement signal emitted by the distance sensor can penetrate through the touch screen, and N is a positive integer greater than or equal to 2.
Here, the terminal 1 may be at least one of a mobile phone, a tablet computer, a notebook computer, an integrated machine, a wearable device, and the like; the wearable device may be a smart watch or the like. It should be noted that the terminal may be any terminal having a touch screen.
Here, the touch screen 10 can be used as a man-machine interaction interface, and when the graphic buttons on the screen are touched, the screen can drive various connection modules according to a preprogrammed program, so as to replace a mechanical button panel and produce vivid audio-visual effects by means of a liquid crystal display.
Here, the distance sensor 110 may be an ultrasonic sensor.
The ultrasonic sensor is a sensor that converts an ultrasonic signal into another energy signal (e.g., an electrical signal). The ultrasonic wave is a mechanical wave with vibration frequency higher than 20kHz, and has high frequency, short wavelength, small diffraction phenomenon, and particularly good directivity. Moreover, the penetration of ultrasonic waves into liquids and solids is very large, especially in solids that are transparent in sunlight, the ultrasonic waves encounter impurities or interfaces and are reflected significantly to form reflected waves, which can produce the multipter effect when striking living bodies. Therefore, in this embodiment, the ultrasonic sensor may be disposed below the touch screen, without additional holes for the ultrasonic sensor, so that the ultrasonic sensor may be integrated below the touch screen in a large area, and the integrity of the touch screen may be better.
In other embodiments, the distance sensor 110 may also be a radar sensor.
The electromagnetic wave signal emitted by the radar sensor is used for measuring the distance via the echo returned by the emitted electromagnetic wave. Because electromagnetic wave also has the penetrability of liquid and solid, consequently, in this embodiment, radar sensor can set up in the touch screen below, need not be the extra trompil of radar sensor, consequently also can integrate in the below of touch screen in a large scale, and can let the wholeness of touch screen better, simultaneously, because radar sensor need not be at terminal surface trompil, just need not vacate the position for radar sensor additionally yet, can increase touch screen surface area, realize bigger screen ratio.
In fact, the distance sensor that transmits the ranging signal to penetrate the touch screen is within the scope defined by the embodiments of the present disclosure, and is not limited in any way.
Further, in this embodiment, the plurality of distance sensors are disposed below the touch screen, so that the area that can be sensed is increased, and further, whether the sensed object within the preset distance of the touch screen is a target object or not can be accurately judged, rather than just judging whether the sensed object is a target object or not, so that whether the sensed object is the target object or not is determined based on the area, and the guarantee is provided for reducing misoperation phenomena of shielding of the touch screen according to control of different scenes realized by the target object. For example, the display state of the touch screen is maintained when the sensing object is the target object, and the display state of the touch screen is exited when the sensing object is not the target object, for example, the touch screen is in a black screen state or a screen locking state, and the touch screen is not controlled to be in the black screen state or the screen locking state as long as the sensing object is shielded.
It should be added that the black screen state means that the touch screen is in a non-bright state, and in general, when the touch screen of the terminal enters the black screen state, the electric quantity of the terminal can be saved, any operation of a user on the touch screen cannot be accepted in the black screen state, and misoperation phenomenon of the touch screen when a sensing object is not a target object is reduced.
In addition, the screen locking state is the locking state of the touch screen, and in the screen locking state, any operation of a user on the touch screen cannot be received, so that the phenomenon of misoperation on the touch screen when a sensing object is not a target object is reduced.
In some embodiments, the N distance sensors are distributed in an array under the touch screen; the area occupied by the array formed by the N distance sensors is larger than an area threshold value and smaller than or equal to the area of the touch screen.
The array may be a rectangular array, a circular array, a trapezoidal array, a triangular array, or the like.
Here, if the array is a rectangular array, referring to fig. 1 again, the N distance sensors 110 may be distributed below the touch screen 10 in an array manner. Here, the N distance sensors 110 may be distributed below the touch screen 10 in a rectangular array of n×m, where N and m are positive integers, N is greater than or equal to 2, or m is greater than or equal to 2, and n×m is equal to N.
If the array is a circular array, the central point of the touch screen can be used as a round point for distribution. Therefore, the distance sensors are uniformly distributed below the touch screen, and the sensing object in the preset distance can be detected through omnibearing detection, so that whether the sensing object is the target object or not can be accurately determined.
Of course, in other embodiments, the circular array may be distributed with the center of the region where the user operation frequency is higher as a dot.
If the array is a trapezoid array, the area with higher user operation frequency can be used as the area where the long side of the trapezoid is located for distribution. If the array is a triangular array, the area with higher user operation frequency can be used as the area where the long side of the triangle is located for distribution. Therefore, more distance sensors are distributed in the area with higher user operation frequency, so that the sensing sensitivity of the distance sensing module can be increased, and meanwhile, the accuracy of detecting whether a target object exists in the preset distance of the touch screen by the distance sensing module can be further improved.
Further, in this embodiment, N distance sensor arrays are distributed, and an area occupied by the array formed by the N distance sensors is greater than an area threshold and less than or equal to an area of the touch screen, so that the touch screen of the terminal can have the distribution of the ultrasonic sensors at least in a preset area, thereby increasing a sensing range of the distance sensing module, and further improving accuracy of detecting whether a target object exists in a preset distance of the touch screen.
Further, in some embodiments, referring to fig. 2, fig. 2 is another schematic diagram of a terminal according to an exemplary embodiment, as shown in fig. 2, the terminal further includes:
the processing module 12 is respectively connected with the touch screen 10 and the distance sensing module 11, and is used for receiving detection information generated by the distance sensing module 11 based on the transmitted ranging signals; according to the detection information, whether the target object exists in the preset distance of the touch screen 10 is determined, and whether the touch screen 10 maintains the display state is controlled according to the determined result.
Here, the processing module 12 generally controls overall operations of the terminal 1, such as operations related to display, telephone call, data communication, camera operations, and recording operations. The processing module 12 may include one or more processors to execute instructions to perform corresponding operations. Here, the processing module may be configured to implement an operation of determining whether the target object is within a predetermined distance of the touch screen 10 according to detection information generated based on the transmitted ultrasonic waves by the receiving distance sensing module 11, and controlling whether the touch screen 10 maintains the display state according to the determined result.
Here, taking a situation that the terminal is in a call state as an example, the processing module is capable of receiving detection information generated by the distance sensing module based on the transmitted ranging signal; and determining whether the target object exists in the preset distance of the touch screen according to the detection information, wherein the target object is a finger, if the target object exists, the touch screen can be controlled to maintain the display state according to the result of the existence of the target object, or if the target object does not exist, the touch screen can be controlled not to maintain the display state according to the result of the non-existence of the target object. In this way, the terminal can determine whether two different results of the target object exist within the preset distance of the touch screen according to the detection information to adapt to two different scene controls. Specifically, when the terminal detects that the target object exists, the touch screen is controlled to maintain the display state, so that the user can still operate the mobile phone by utilizing finger touch in the call state, and the phenomenon that the mobile phone cannot be operated due to the fact that the screen is turned on as long as the sensing object exists in the related technology is avoided. When the terminal detects that no target object exists, that is, the detection information indicates that the sensed sensing object is not a finger, the terminal can be controlled to not maintain the display state any more, and false touch control on the terminal during operations such as face pasting and the like is reduced.
Of course, in other scenes, for example, the terminal is in a file editing scene, if the security requirement of the scene on the file is higher, the terminal determines whether the target object exists within the preset distance of the touch screen according to the detection information, and according to different determined results of the determined target object or the determined non-target object, different control on the display state of the touch screen is realized. Here, assuming that the target object is a finger, file editing may be continued when it is determined that there is a target object, and when there is no single finger, for example, a palm, prompt control of the terminal to exit from a display state, for example, a black screen state, may be achieved. Therefore, different operations can be rapidly switched through different sensing objects, so that reading or stealing of file contents by bystanders is reduced, and the confidentiality effect of file editing is improved.
In this embodiment, whether the touch screen maintains the display state is controlled by the determination result of whether the target object exists within the preset distance of the touch screen, so that control of a single scene for determining whether to maintain the display state as long as the sensing object exists within the preset distance of the touch screen (i.e., the touch screen is blocked) can be reduced. The misoperation phenomenon that corresponding operation is executed only when the sensing object exists within the preset distance of the touch screen is reduced, for example, the misoperation phenomenon that the touch screen is controlled to enter a black screen state only when the sensing object exists within the preset distance of the touch screen is reduced.
In some embodiments, referring to fig. 2, the distance sensor 110 includes: an ultrasonic sensor; the ranging signal includes: an ultrasonic wave emitted by the ultrasonic wave; the processing module 12 is further configured to determine, according to the detection information, the number of the ultrasonic sensors that detect the return wave of the ultrasonic wave; determining whether the area of the sensing object in the preset distance covered on the touch screen is smaller than a preset threshold value or not according to the number of the ultrasonic sensors; and if the area of the sensing object covered on the touch screen is smaller than the preset threshold, determining the sensing object as the target object, and controlling the touch screen to maintain the display state.
Here, the ultrasonic sensor that detects the return wave of the ultrasonic wave may be understood as the ultrasonic sensor covered by the sensing object within the preset distance.
It can be understood that, in the case that the ultrasonic sensors are distributed in a certain manner, the greater the number of the ultrasonic sensors that detect the ultrasonic return wave, the greater the area of the sensing object within the preset distance that can be covered on the touch screen, and conversely, the smaller the area of the sensing object within the preset distance that can be covered on the touch screen.
Therefore, according to the present embodiment, the area of the sensing object covered on the touch screen can be determined according to the number of the ultrasonic sensors that detect the return wave of the ultrasonic wave, and whether the sensing object is a target object or not is determined based on whether the area is smaller than the preset threshold, if the sensing object is the target object, the touch screen is controlled to maintain the display state. Therefore, by detecting the number of the ultrasonic sensors of the return waves of the ultrasonic waves and the area of the sensing object covered on the touch screen, whether the area of the sensing object covered on the touch screen is smaller than the preset threshold value can be rapidly judged, whether the sensing object is a target object or not is determined, the operation efficiency of the terminal is improved, and the judging efficiency of the terminal to the target object is improved.
In another embodiment, referring to fig. 2, the processing module 12 is further configured to determine that the target object is not present within the preset distance of the touch screen if the area of the sensing object covered on the touch screen is greater than or equal to the preset threshold, and control the touch screen to enter a black screen state or a lock screen state.
In this way, the embodiment controls the touch screen to maintain the display state only when the sensing object is the target object, and controls the touch screen to enter the black screen state or the lock screen state when the sensing object is not the target object, so as to reduce the misoperation phenomenon that the touch screen is controlled to enter the black screen state or the lock screen state when any sensing object is sensed.
In other embodiments, the processing module 12 is further configured to determine, according to the number of the ultrasonic sensors, a first duty ratio of the ultrasonic sensors that detect the return waves of the ultrasonic waves to the N ultrasonic sensors; and determining whether the area of the sensing object covered on the touch screen is smaller than the preset threshold according to the first duty ratio.
It is understood that the ultrasonic sensors that detect the return waves of the ultrasonic waves occupy the first occupation ratios of the N ultrasonic sensors, which can indicate the area of the sensing object covered on the touch screen, so that it can be determined whether the area of the sensing object covered on the touch screen is smaller than the preset threshold according to the first occupation ratio.
Further, the processing module 12 is further configured to determine, according to the first duty cycle, whether the first duty cycle is less than a duty cycle threshold; and if the first duty ratio is smaller than the duty ratio threshold, determining that the area of the sensing object covered on the touch screen is smaller than the preset threshold, or if the first duty ratio is larger than or equal to the duty ratio threshold, determining that the area of the sensing object covered on the touch screen is larger than or equal to the preset threshold.
Here, the duty ratio threshold may be preset in the terminal based on the area of the target object covered on the touch screen, in this embodiment, by directly comparing the first duty ratio with the duty ratio threshold, conversion between the number of ultrasonic sensors and the area of the sensing object covered on the touch screen is not required, and it may be very convenient and fast determined whether the area of the sensing object covered on the touch screen is smaller than the preset threshold, so as to determine whether the sensing object is the target object, further improve the operation efficiency of the terminal, and further improve the determination efficiency of the terminal for the target object.
In other embodiments, the processing module 12 is further configured to control the ultrasonic wave emitted by the distance sensing module to detect whether the target object is within the preset distance of the touch screen if the terminal is detected to be in a call state.
In this embodiment, by controlling the timing of the distance sensing module to emit ultrasonic waves, that is, controlling the distance sensing module to emit ultrasonic waves only when the terminal is detected to be in a call state, energy consumption of the terminal can be saved.
Here, the call state includes: in the state of a packet-switched voice call or an instant messaging based call. The voice call in packet switching may be, for example, a voice call performed through an operator network; the instant messaging-based call may be, for example, a call made through even communication software (e.g., a micro message, etc.) installed in the terminal.
Further, the present disclosure also provides a specific embodiment to further understand the terminal provided by the embodiments of the present disclosure.
In this embodiment, the terminal uses a mobile phone as an example.
In some scenarios, for example, when making a call, it is often necessary to operate the handset, such as looking at some address book, or some content to tell the party to the incoming call. At this time, the call is returned to the desktop by pressing the primary key, the call programming small green bar is displayed at the uppermost part of the touch screen, and then some desktop or application software operations are performed. However, when the finger performs some operations such as pulling down, the finger may touch the infrared sensor above the touch screen, and the finger is mistakenly considered as a face by the infrared sensor, so that the touch screen is controlled to enter a black screen state or a screen locking state, and cannot enter the touch operation, resulting in poor user experience.
Based on this, referring to fig. 1 and 2 again, the present embodiment replaces the infrared sensor with the ultrasonic sensor in the related art. Here, the N ultrasonic sensors 110 are located below the touch screen 10, where N is a positive integer greater than or equal to 2. Because the ultrasonic wave has strong penetrating power to liquid and solid and good directivity, the mode does not need to be provided with holes on the surface like an infrared sensor, so that the ultrasonic sensor can be embedded below the touch screen 10 instead of on the surface, the integrity of the touch screen can be ensured, and meanwhile, the higher screen duty ratio can be ensured.
In this embodiment, the N ultrasonic sensors need not be completely distributed on the touch screen, and may be distributed in an n×m array, where N is 15 and n×m may be 3*5, i.e. distributed under the entire touch screen in an array 3 and an array 4.
Further, in this embodiment, when the processing module 12 of the mobile phone detects that the mobile phone is talking, all the ultrasonic sensors are controlled to be turned on, and whether the sensing object is close to the touch screen is detected. If the sensing object is a face, the ultrasonic sensor which at least exceeds the duty ratio threshold senses the sensing object, and if the ultrasonic sensor which exceeds the duty ratio threshold senses the sensing object, the sensing object can be considered to be in a normal face-to-phone state, so that the touch screen is controlled to enter a black screen state or a screen locking state, and the false touch of the face is reduced.
However, if the sensing object is a finger, the duty ratio of the ultrasonic sensor sensing the sensing object is lower than the duty ratio threshold, and if the ultrasonic sensor sensing the sensing object is smaller than the duty ratio threshold, the sensing object is considered to be a target object, that is, the finger is approaching, so that the touch screen is controlled to maintain the display state, and the misoperation phenomenon of the face black screen is reduced.
In this embodiment, through a plurality of ultrasonic sensors that set up under the touch screen, can more accurate discernment user's scene and intention, make things convenient for the switching operation of user under different scenes, improved the user experience of user's operation cell-phone in the conversation greatly. The method and the device realize higher and accurate recognition of whether the gesture of answering the phone is the face, achieve accurate black screen false touch prevention, and simultaneously achieve the aim of normal operation of the mobile phone which is not the face during conversation.
