Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings.

The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
With the continuous development of intelligent devices, the TDDI touch screen has unique advantages and is more and more widely used in life. The TDDI touch screen integrates the originally external touch panel component and the liquid crystal panel in different modes, the driving voltage of the TDDI touch screen needs time-sharing multiplexing to drive the display and touch modules, the voltage waveform for driving the display module is constant voltage, the voltage waveform for driving the touch modules is pulse signals, and the TDDI touch screen generates periodically-changed driving voltage switching frequency in the time-sharing multiplexing process. The periodically-changed driving voltage electrode and the metal frame of the display backlight module are used as two electrodes of a capacitor, and Thin Film Transistor (TFT) glass, air and a backlight Film material are used as media, so that a coupling capacitor structure is formed. The screen is caused to sound due to the howling effect of the capacitor. In order to solve the problem of screen sounding, the embodiments of the present disclosure provide a method and an apparatus for processing sounding of a TDDI touch screen.
Hereinafter, exemplary implementation scenarios of the embodiments of the present disclosure will be described.
When a smart device using a TDDI touch screen is used, generally in a quiet environment, and when the TDDI touch screen of the smart device is bright, the TDDI touch screen may emit a slight sound, for example, during a process of using the smart device to watch a video in a quiet environment at night, and further for example, during a process of using the smart device to talk and a process of using the smart device to face or ear, the sound emitted from the screen may be heard.
Fig. 1 is a flowchart illustrating a method for processing TDDI touchscreen sounds according to an exemplary embodiment, where the method may be performed by an apparatus for processing TDDI touchscreen sounds, the apparatus may be implemented by software and/or hardware, the apparatus may be part or all of a terminal device including a TDDI touchscreen, the terminal device may be a personal computer, a smart phone, a user terminal, a tablet computer, a wearable device, or the like, and the method for processing TDDI touchscreen sounds is described below with the terminal device including a TDDI touchscreen as an execution subject. As shown in fig. 1, the method for processing TDDI touchscreen utterances provided by the present disclosure may include the following steps:
step S101: and detecting whether a user touch operation exists on the touch and display driver integrated TDDI touch screen.
The detection of whether the user touch operation exists on the TDDI touch screen can be realized through a touch sensor on the TDDI touch screen.
The user touch operation may include touch operation, sliding operation, long-press operation, and the like, and the embodiment of the present invention does not limit the specific operation of the user touch operation, and in addition, the user touch operation on the TDDI touch screen may be an operation of using a finger, a palm, a face, or the like by the user.
Step S102: if no user touch operation exists, switching the scanning mode of the TDDI touch screen from an active scanning mode to a target scanning mode, wherein a voltage waveform of the target scanning mode is composed of N first waveform frames and M second waveform frames, N is an integer larger than two, M is an integer larger than or equal to zero, each first waveform frame at most comprises one touch pulse waveform, each second waveform frame comprises a plurality of touch pulse waveforms, and a voltage waveform of the active scanning mode is composed of a plurality of second waveform frames.
If there is no user touch operation, switching the scanning mode of the TDDI touch screen from the active scanning mode to the target scanning mode, in one possible implementation, including: and if no user touch operation exists within the preset time length, switching the scanning mode of the TDDI touch screen from the active scanning mode to the target scanning mode.
The method and the device have the advantages that the preset time length is set, the frequent switching of the scanning mode of the TDDI touch screen is avoided, the length of the preset time length is not limited, and in a possible implementation mode, the scanning mode of the TDDI touch screen is switched from the active mode to the target scanning mode when the user touch operation is not performed within 1 second.
In a scanning mode of the TDDI touch screen, the TDDI touch screen performs time-sharing scanning, and cyclically scans with a display waveform and a touch pulse waveform as a cycle, wherein the number of cycles scanned by the TDDI touch screen in one second is a scanning frequency of the TDDI touch screen, and currently, in an active scanning mode, the scanning frequency of the TDDI touch screen is approximately between 240 hz and 2 khz. In addition, the display waveform is a voltage waveform of the TDDI touch screen when driving the display module, and the driving of the display module generally adopts a constant voltage, so the display waveform is a straight line, the touch pulse waveform is a voltage waveform of the TDDI touch screen when driving the touch module, and the driving of the touch module generally requires a pulse signal, so the touch pulse waveform is a pulse signal, for example, a square wave signal, and the like.
In the process that a user operates the TDDI touch screen through finger touch, the scanning mode of the TDDI touch screen is an active scanning mode, wherein the voltage waveform of the active scanning mode is formed by a plurality of second waveform frames. Waveform frame in this disclosure means a frame of waveform, calculated to scan 120 frames in one second, with a waveform frame time of approximately 8.33 milliseconds (ms). The number of the second waveform frames is not limited in the embodiments of the present disclosure, and the second waveform frames include a plurality of touch pulse waveforms.
Taking the active scan mode including two second waveform frames, each of the second waveform frames including two touch pulse waveforms as an example, the active scan mode of the TDDI touch screen is described, fig. 2 is a schematic diagram of the active scan mode according to an exemplary embodiment, as shown in fig. 2, where a display module (DP) indicates a display function operation of the TDDI touch screen, a touch module (TP) indicates a touch function operation of the TDDI touch screen, the second waveform frame 21 includes two periods 22, and each period includes one display waveform 23 and one touch pulse waveform 24.
When no user touch operation exists, the scanning mode of the TDDI touch screen is switched from an active scanning mode to a target scanning mode, wherein the voltage waveform of the target scanning mode is composed of N first waveform frames and M second waveform frames, N is an integer larger than two, M is an integer larger than or equal to zero, each first waveform frame at most comprises one touch pulse waveform, and each second waveform frame comprises a plurality of touch pulse waveforms. In the N first waveform frames, each first waveform frame may include one touch pulse waveform, or the first waveform frame including one touch pulse waveform and the first waveform frame not including the touch pulse waveform are cyclically scanned, for example, in the N first waveform frames, the first waveform frame includes one touch pulse waveform, the second first waveform frame does not include the touch pulse waveform, the third first waveform frame includes one touch pulse waveform, and so on until the nth first waveform frame.
In the target scan pattern, if M is equal to zero, the voltage waveform of the target scan pattern is composed of N first waveform frames, fig. 3 is a schematic diagram of the target scan pattern according to an exemplary embodiment, and as shown in fig. 3, the target scan pattern includes three first waveform frames 31, where each first waveform frame 31 includes one touch pulse waveform 32 and one display waveform 33. In the target scanning mode where M is equal to zero, the TDDI touch screen scans cyclically with the first waveform frame.
If M is greater than zero, the voltage waveform of the target scan pattern is composed of N first waveform frames and M second waveform frames, fig. 4 is a schematic diagram of the target scan pattern according to another exemplary embodiment, as shown in fig. 4, the voltage waveform of the target scan pattern is composed of N first waveform frames 41 and M second waveform frames 42, and scanning of the TDDI touch screen during the operation of detecting no user touch is realized by cyclically scanning the N first waveform frames 41 and the M second waveform frames 42. The number of the first waveform frames and the second waveform frames is not limited in the embodiments of the present invention, and in a possible implementation manner, the voltage waveform of the target scan pattern is composed of 360 first waveform frames and 1 second waveform frame.
To sum up, according to the method for processing sound emission of the TDDI touch screen provided by the embodiment of the present disclosure, when it is detected that there is no user touch operation, the scanning mode of the TDDI touch screen is switched from the active scanning mode to the target scanning mode, and because the scanning frequency of the target scanning mode reasonably avoids the vibration frequency of the TDDI touch screen, the problem of sound emission of the TDDI touch screen when there is no user touch operation is solved, and meanwhile, because the number of the second waveform frames in the target scanning mode is reduced, the voltage consumed by the TDDI touch screen is reduced due to the reduction of the number of the touch pulse waveforms scanned by the TDDI touch screen, and power consumption can be effectively reduced.
On the basis of the foregoing embodiments, in step S101, upon detection, there may be a user touch operation on the TDDI touch screen, and for a case that the user touch operation on the TDDI touch screen is detected, in one possible implementation, fig. 5 is a flowchart of a method for processing sounding of the TDDI touch screen according to another exemplary embodiment, where the method may be performed by an apparatus for processing sounding of the TDDI touch screen, where the apparatus may be a part or all of a terminal device including the TDDI touch screen, and the terminal device may be a personal computer, a smart phone, a user terminal, a tablet computer, a wearable device, or the like, and the method for processing sounding of the TDDI touch screen is described below with the terminal device including the TDDI touch screen as an execution subject. As shown in fig. 5, the method for processing a TDDI touchscreen utterance provided by the present disclosure may further include:
step S501: and if the TDDI touch screen has the user touch operation, judging whether the user touch operation is the first user operation.
If the TDDI touch screen has the user touch operation, whether the user touch operation is the first user operation may be determined through the touch chip, the central processing unit, and the like.
Optionally, the first user operation is at least one of: finger touch operation, long press operation, and slide operation.
Fig. 6 is an interface diagram illustrating a first user operation according to another exemplary embodiment, taking a terminal device including a TDDI touch screen as a mobile phone, for example, as shown in fig. 6, the first user operation performed by the user on the TDDI touch screen is a finger touch operation or a long-press operation.
Step S502: and if the user touch operation is the first user operation, controlling the scanning mode of the TDDI touch screen to be an active scanning mode.
If it is determined that the user touch operation is the first user operation, taking fig. 6 as an example, and the first user operation is the touch operation or the long-press operation, the scanning mode of the TDDI touch screen is controlled to be the active scanning mode.
To sum up, the method for processing sound emission of the TDDI touch screen according to the embodiment of the present disclosure controls the scanning mode of the TDDI touch screen to be the active scanning mode when it is determined that the user touch operation is the first user operation, so that the display and touch functions of the TDDI touch screen during the first user operation are realized.
If there is a user touch operation on the TDDI touch screen after the detection in step S101, in another possible implementation, fig. 7 is a flowchart of a method for processing sounding of the TDDI touch screen according to yet another exemplary embodiment, where the method may be executed by an apparatus for processing sounding of the TDDI touch screen, the apparatus may be implemented by software and/or hardware, the apparatus may be part or all of a terminal device including the TDDI touch screen, the terminal device may be a personal computer, a smart phone, a user terminal, a tablet computer, a wearable device, or the like, and the method for processing sounding of the TDDI touch screen is described below with the terminal device including the TDDI touch screen as an execution subject. As shown in fig. 7, the method for processing a TDDI touchscreen utterance provided by the present disclosure may further include:
step S701: and if the TDDI touch screen has the user touch operation, judging whether the user touch operation is the second user operation.
If the TDDI touch screen has the user touch operation, whether the user touch operation is the second user operation may be determined through the touch chip, the central processing unit, and the like.
The second user operation may be a non-touch operation of the TDDI touch screen by the user, and the second user operation cannot control the terminal device including the TDDI touch screen according to a position and an action of the second user operation, for example, the second user operation is that the user touches the TDDI touch screen with a palm, or the terminal device including the TDDI touch screen is pasted on a face, and the like, and in one possible embodiment, the second user operation includes: and (4) performing user touch operation when the user touches the TDDI touch screen and exceeds a preset area threshold value.
The method and the form for setting the preset area threshold value are not limited in the embodiment of the present invention. And when the TDDI touch screen touched by the user exceeds the preset area threshold, judging that the touch operation of the user is a second user operation. The embodiment of the invention does not limit the way of judging whether the TDDI touch screen touched by the user exceeds the preset area threshold value, and in a possible implementation mode, the TDDI touch screen touched by the user can be judged according to the number of the touch node capacitors covered.
Fig. 8 is an interface diagram illustrating a second user operation according to yet another exemplary embodiment, taking a terminal device including a TDDI touch screen as an example of a mobile phone, where the second user operation performed by the user on the TDDI touch screen is performed by covering a part of a palm of the user on the TDDI touch screen as illustrated in fig. 8.

If it is determined that the user touch operation is a second user operation, taking fig. 8 as an example, and the second user operation is that a partial palm of the user covers the TDDI touch screen, the scanning mode of the TDDI touch screen is controlled to be the target scanning mode.
