So, this embodiment is through can launch the test signal that pierces through the touch-control screen the distance sensor replaces the infrared ray distance sensor who sets up at the touch-control screen top among the correlation technique, because distance sensor can launch and pierce through the range finding signal of touch-control screen, ultrasonic sensor's ultrasonic signal for example pierces through liquid and fixed penetrability is strong, consequently need not to carry out the trompil for the touch-control screen for the wholeness of touch-control screen is better, and realizes that bigger screen accounts for than.

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 the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the invention, as detailed in the appended claims.

Fig. 1 is a schematic diagram of a terminal according to an exemplary embodiment, where, as shown in fig. 1, the terminal 1 includes:

a touch screen 10;

distance sensing module 11 includes: the N distance sensors 110 are located below the touch screen 10, and configured to detect whether a target object is located within a preset distance of the touch screen 10 by transmitting a ranging signal; the distance measuring 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 all-in-one machine, a wearable device, and the like; wherein, wearable equipment can be smart watch etc.. It should be noted that the terminal may be any terminal with a touch screen.

Here, the touch screen 10 can be used as a human-computer interaction interface, when a graphic button on the screen is touched, the screen can drive various connection modules according to a pre-programmed program, so as to replace a mechanical button panel and produce vivid video and audio effects by means of a liquid crystal display screen.

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 a vibration frequency higher than 20kHz, and has high frequency, short wavelength, small diffraction phenomenon and good directivity. In addition, the ultrasonic wave has great penetrating power to liquid and solid, and especially in transparent solid in sunlight, the ultrasonic wave can generate obvious reflection to form reflected wave when contacting impurities or interfaces, and can generate multi-peter effect when contacting moving objects. Therefore, in this embodiment, ultrasonic sensor can set up in the touch screen below need not be for ultrasonic sensor extra trompil, consequently also can integrate in the below of touch screen by large area ground, and can let the wholeness of touch screen is better, simultaneously, because ultrasonic sensor need not just need not additionally vacate the position for ultrasonic sensor at terminal surface trompil, can increase touch screen area, realizes bigger screen ratio.

In other embodiments, the distance sensor 110 may also be a radar sensor.

The distance measurement is carried out by the aid of the echo returned by the transmitted electromagnetic waves through electromagnetic wave signals transmitted by the radar sensor. Because the electromagnetic wave also has the penetrability of liquid and solid, consequently, in this embodiment, radar sensor can set up in touch screen below need not be for radar sensor extra trompil, consequently also can integrate in touch screen's below by large area ground, and can let touch screen's wholeness better, simultaneously, because radar sensor need not at terminal surface trompil, also need not additionally vacate the position for radar sensor, can increase touch screen area, realizes bigger screen area.

In fact, the range 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 thereto.

Further, in this embodiment, the distance sensors are arranged below the touch screen, so that the area sensed by the distance sensors is increased, and then whether the sensing object in the preset distance of the touch screen is the target object can be judged more accurately, rather than just slightly judging whether the shielding exists, so that whether the target object is determined based on the area subsequently, and the misoperation phenomenon of the touch screen on shielding is reduced according to the 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 enters the blank screen state or the lock screen state, rather than being controlled to enter the blank screen state or the lock screen state as long as there is shielding.

It is to be added that the black screen state refers to that the touch screen is in a non-lit state, and generally, the touch screen of the terminal enters the black screen state, so that not only can the electric quantity of the terminal be saved, but also any operation of a user on the touch screen cannot be received in the black screen state, and the phenomenon of misoperation on 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 any operation of a user on the touch screen cannot be received in the screen locking state, so that the phenomenon of misoperation of 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 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, or a triangular array, etc.

Here, if the array is a rectangular array, please refer to fig. 1 again, the N distance sensors 110 may be arranged below the touch screen 10 in an array. 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, and 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 points of the touch screen can be distributed as dots. Therefore, the distance sensors are uniformly distributed below the touch screen, so that the sensing object in a preset distance can be detected in an all-around manner, and 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 area with higher user operation frequency as a dot.

If the array is a trapezoid array, the region with higher user operation frequency can be distributed as the region where the longer side of the trapezoid is located. If the array is a triangular array, the area with high user operation frequency can be distributed as the area where the long side of the triangle is located. Therefore, more distance sensors are distributed in the area with higher user operation frequency, 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.

Furthermore, in this embodiment, the N distance sensor arrays are distributed, and an area occupied by the array formed by the N distance sensors is larger than an area threshold and smaller 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, and thus the sensing range of the distance sensing module is increased, and the accuracy of detecting whether a target object exists in the preset distance of the touch screen is improved.

Further, in some embodiments, referring to fig. 2, fig. 2 is another schematic diagram of a terminal according to an exemplary embodiment, and 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 configured to receive detection information generated by the distance sensing module 11 based on the transmitted ranging signal; and determining whether the target object exists within a preset distance of the touch screen 10 according to the detection information, and controlling whether the touch screen 10 maintains a display state according to a determined result.

Here, the processing module 12 generally controls the overall operations of the terminal 1, such as operations related to display, telephone call, data communication, camera operation, and recording operation. 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 preset distance of the touch screen 10 according to detection information generated by receiving the distance sensing module 11 based on the transmitted ultrasonic wave, and controlling whether the touch screen 10 maintains a display state according to a result of the determination.

Here, taking a scene of the terminal in a call state as an example, the processing module may receive detection information generated by the distance sensing module based on the transmitted ranging signal; and determining whether the target object exists within a preset distance of the touch screen or not according to the detection information, wherein the target object is a finger, and if the target object exists, controlling the touch screen to maintain the display state according to the result of the existence of the target object, or if the target object does not exist, controlling the touch screen not to maintain the display state according to the result of the nonexistence of the target object. Therefore, 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 a target object, the touch screen is controlled to maintain the display state, so that the user can still operate the mobile phone by using finger touch in the call state, and the phenomenon that the operation cannot be performed due to the fact that the screen is blacked as long as a sensing object is detected in the related art does not occur. When the terminal detects no target object, namely the detection information indicates that the sensed sensing object is not a finger, the terminal can be controlled not to maintain the display state any more, and the mistaken touch control on the terminal during operations such as face pasting is reduced.

Certainly, in some other scenarios, for example, when the terminal is in a file editing scenario, if the security requirement of the scenario on the file is high, the terminal determines whether the target object exists within the preset distance of the touch screen according to the detection information, and realizes different controls on the touch screen with respect to the display state according to different determination results of whether the target object exists or does not exist. Here, assuming that the target object is a finger, when it is determined that there is a target object, file editing can be continued, and when there is no single finger, for example, a palm, rapid control of the terminal to exit from a display state, for example, a black screen state, can be achieved. Therefore, different operations can be quickly switched by sensing different objects, so that reading or stealing of the file contents by other people is reduced, and the security effect during 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 the control of determining whether to maintain the single scene of the display state as long as the sensing object exists within the preset distance of the touch screen (i.e., the touch screen is shielded) can be reduced. The misoperation phenomenon that corresponding operation is executed as long as 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 as long as 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: the ultrasonic waves emitted by the ultrasonic waves; the processing module 12 is further configured to determine, according to the detection information, the number of the ultrasonic sensors that detect the return waves of the ultrasonic waves; determining whether the area of the touch screen covered by the sensing object within the preset distance is smaller than a preset threshold value or not according to the number of the ultrasonic sensors; if the area of the touch screen covered by the sensing object is smaller than the preset threshold, determining that the sensing object is 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 that is covered by a sensing object within the preset distance.

It can be understood that, under the condition that the ultrasonic sensors are distributed in a certain manner, the larger the number of the ultrasonic sensors detecting the ultrasonic return waves is, the larger the area of the touch screen that can be covered by the sensing object within the preset distance is, and conversely, the smaller the area of the touch screen that can be covered by the sensing object within the preset distance is.

Therefore, in this embodiment, the area of the touch screen covered by the sensing object can be determined according to the number of the ultrasonic sensors that detect the return waves of the ultrasonic waves, and then whether the sensing object is the target object is determined based on whether the area is smaller than the preset threshold, and if the sensing object is the target object, the touch screen is controlled to maintain the display state. Therefore, through simple conversion between the number of the ultrasonic sensors which detect the return waves of the ultrasonic waves and the area of the touch screen covered by the sensing object, whether the area of the touch screen covered by the sensing object is smaller than the preset threshold value or not can be quickly judged, so that whether the sensing object is a target object or not is determined, the operation efficiency of the terminal is improved, and the judgment efficiency of the terminal for 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 a preset distance of the touch screen and control the touch screen to enter a blank screen state or a screen locking state if an area of the touch screen covered by the sensing object is greater than or equal to the preset threshold.

Therefore, the embodiment realizes that the touch screen is controlled to maintain the display state only when the sensing object is the target object, and the touch screen is still controlled to enter the blank screen state or the screen locking state when the sensing object is not the target object, so that the phenomenon of misoperation of controlling the touch screen to enter the blank screen state or the screen locking state when any sensing object is sensed is reduced.

In other embodiments, the processing module 12 is further configured to determine, according to the number of the ultrasonic sensors, a first 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 touch screen covered by the sensing object is smaller than the preset threshold value or not according to the first proportion.

It is understood that the first ratio of the ultrasonic sensor to the N ultrasonic sensors, at which the return waves of the ultrasonic waves are detected, is indicative of the area of the touch screen covered by the sensing object, so that it can be determined whether the area of the touch screen covered by the sensing object is smaller than the preset threshold value according to the first ratio.

Further, the processing module 12 is further configured to determine whether the first duty ratio is smaller than a duty ratio threshold according to the first duty ratio; if the first ratio is smaller than the ratio threshold, it is determined that the area of the touch screen covered by the sensing object is smaller than the preset threshold, or if the first ratio is larger than or equal to the ratio threshold, it is determined that the area of the touch screen covered by the sensing object is larger than or equal to the preset threshold.

Here, the occupation ratio threshold may be preset in the terminal based on the area of the target object covered on the touch screen, in this embodiment, directly by comparing the first occupation ratio with the occupation ratio threshold, without performing conversion between the number of the ultrasonic sensors and the area of the touch screen covered by the sensing object, it may be determined conveniently and quickly whether the area of the touch screen covered by the sensing object is smaller than the preset threshold, so as to determine whether the sensing object is the target object, thereby further improving the operation efficiency of the terminal, and further improving the determination efficiency of the terminal for the target object.

In other embodiments, the processing module 12 is further configured to control the ultrasonic waves emitted by the distance sensing module to detect whether the target object exists within a preset distance of the touch screen if the terminal is detected to be in a call state.

In this embodiment, by controlling the time when the distance sensing module transmits the ultrasonic wave, that is, only when the terminal is detected to be in a call state, the distance sensing module is controlled to transmit the ultrasonic wave, so that the energy consumption of the terminal can be saved.

Here, the call state includes: in a state of a packet switched voice call or in a state of an instant messaging based call. The voice call in packet switching may be, for example, a voice call over a carrier network; the instant messaging based call may be, for example, a call made through instant messaging software (such as WeChat) installed in the terminal.

Further, the present disclosure also provides a specific embodiment to further understand the terminal provided by the embodiment of the present disclosure.

In this embodiment, the terminal is 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 calling party. At the moment, the call is returned to the desktop by pressing the main key, the call programming small green bar is displayed at the top of the touch screen, and then the operation of some desktop or application software is performed. However, when a finger is performing some operations such as pulling down, the finger may contact the infrared sensor above the touch screen, and the finger is mistaken as a face by the infrared sensor, and the touch screen is controlled to enter a black screen state or a screen locking state, and cannot enter a touch operation, so that the user experience is poor.

Based on this, referring to fig. 1 and fig. 2 again, the infrared sensor in the related art is replaced by an ultrasonic sensor in the present embodiment. 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 is strong to the penetrating power of liquid, solid, and the directionality is good, and this kind of mode need not to be like infrared sensor need be at the surperficial trompil moreover, consequently can be with ultrasonic sensor embedding touch-control screen 10 below, but not the surface, can guarantee touch-control screen's wholeness, can guarantee higher screen to account for the ratio simultaneously.

In this embodiment, the N ultrasonic sensors do not need to be completely distributed on the touch screen, and may be arranged in an N × m array distribution, where N is 15, and N × m may be 3 × 5, that is, the N × m ultrasonic sensors are distributed in an array 3 and 4 under the entire touch screen.

Further, in this embodiment, when the processing module 12 of the mobile phone detects that the mobile phone is in a call, all the ultrasonic sensors are controlled to be turned on to detect whether a sensing object is close to the touch screen. If the sensing object is a face, the sensing object is sensed by the ultrasonic sensor at least exceeding the proportion threshold, and if the sensing object is sensed by the ultrasonic sensor exceeding the proportion threshold, the sensing object can be considered to be in a normal face-mounted telephone answering state, so that the touch screen is controlled to enter a black screen state or a screen locking state, and the face-mounted mistaken touch is reduced.

However, if the sensing object is a finger, the ratio of the ultrasonic sensor sensing the sensing object is lower than the ratio threshold, and if the ultrasonic sensor less than the ratio threshold senses the sensing object, it can be considered as a target object, that is, the finger is approaching, so that the touch screen is controlled to maintain a display state, and the phenomenon of misoperation of attaching a face and a black screen is reduced.

In the embodiment, the scenes and intentions of the user can be identified more accurately by the ultrasonic sensors arranged under the touch screen, so that the switching operation of the user under different scenes is facilitated, and the user experience of operating the mobile phone in a call by the user is greatly improved. Whether the gesture of answering a call for the face of the user is recognized accurately, accurate black screen mistaken touch prevention is achieved, and meanwhile the aim of normal operation of the mobile phone which is not face-attached can be achieved during conversation.
