[0059] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings.

The embodiments described in the following exemplary embodiments are not intended to represent all possible embodiments consistent with the present disclosure.

[0062] With the rapid development and widespread adoption of mobile devices like smartphones and tablets, touchscreens, as the most crucial interface for human-computer interaction, are finding increasing use in a wide range of scenarios. As a crucial factor impacting user experience, optimizing touch response latency has become a pressing issue. Existing technologies often struggle to balance response latency with hardware and software power consumption.

[0063] In view of this, the present disclosure provides a touch scanning method, apparatus, computer device, and storage medium.

[0064] Next, the embodiments of the present disclosure are described in detail.

[0065] The first aspect of the present disclosure provides a touch scanning method. Figure 1 , which includes the following steps:

[0066] Step S101, performing touch scanning based on a first sample during a current refresh blank period of the touch display screen, wherein the touch scanning is used to collect interaction events of the touch display screen;

[0067] Step S102: in response to the touch scan based on the first sample capturing an interaction event, performing touch scan based on the second sample during a current refresh blank period of the touch display screen;

[0068] The number of points collected by the second sampling in each sampling round is greater than the number of points collected by the first sampling in each sampling round, and / or the number of sampling rounds for the second sampling is greater than the number of sampling rounds for the first sampling.

[0069] For a touch screen display, the interaction event may refer to a contact event between a part of the human body and the touch screen display (i.e., a touch event), such as a joint touch event, a fingertip touch event, etc. The refresh blank period may refer to a row refresh blank period generated after the touch screen display completes a row refresh (i.e., after the display screen refreshes a row of pixels, it switches to the next row for refresh and generates a refresh blank period, which is also commonly referred to as Hsync Blanking), or a frame refresh blank period generated after the touch screen display completes a frame refresh (i.e., after the display screen completes a frame page refresh, it waits for the next frame refresh and generates a frame refresh blank period, which is also commonly referred to as Vsync Blanking; wherein, each frame refresh may be triggered by a vertical synchronization signal sent by a processor or other related components). Based on this, time-sharing multiplexing of the touch and display functions of the touch screen display can be achieved, reducing the difficulty of circuit design and increasing the service life of the touch screen display. Optionally, the above method can be executed during the frame refresh blank period of the touch display screen, so that the first sampling and the possible second sampling can be completed within the same refresh blank period without changing the refresh rhythm of the touch display screen, so as to minimize the aging speed and damage risk of the display screen.

[0070] The sampling (i.e., the first sampling, the second sampling, etc.) may refer to the specific sampling process performed on the touch display screen during the scanning process (i.e., touch scanning) of the touch display screen for detecting the interactive event. In the following text, “performing touch scanning based on the first sampling” may be referred to as “performing first sampling”, and “performing touch scanning based on the second sampling” may be referred to as “performing second sampling”, but the meaning of the representation remains unchanged. This scanning process is usually composed of multiple sampling rounds. In each sampling round, the execution module of the method can sample preset points on the touch display screen (for example, the screen is divided into 200 rows and 50 columns, and then in each sampling round, it is determined whether an interactive event occurs in the 10,000 grids composed of the 200 rows and 50 columns, and the 10,000 grids are the preset points), and then the above sampling rounds are repeated a preset number of times to obtain more samples and improve the signal-to-noise ratio. In other words, the accuracy of this scanning process (which can also be understood as the signal-to-noise ratio of the samples collected during the scanning process) is generally determined by two dimensions: the number of points collected in each sampling round, that is, the scanning granularity of each sampling round; and the number of sampling rounds (that is, the number of times the sampling process is repeated for the entire screen). Each sampling round is a complete execution unit of the scanning process for an area (such as the entire screen or a sub-area of ​​the screen). For example, one sampling method may scan 50 points on the screen in each sampling round and repeat this process twice (that is, the number of sampling rounds is 2). Exemplarily, the first sampling can be the usual Doze Scan (or low-precision sampling), and the second sampling can be the usual Active Scan (or high-precision sampling) or a customized sampling. Optionally, when the second sampling is a customized sampling, the accuracy of the second sampling can be made between the Doze Scan and the Active Scan to achieve a better balance between response time, power consumption, and screen aging speed. In addition, the software algorithm corresponding to the second sampling can also be simplified on the basis of Active Scan (or other customized software algorithms can be used) to shorten the execution time of the second sampling as much as possible while ensuring the accuracy of the second sampling, so that the first sampling and the second sampling can be completed within the same refresh blank period without changing the original refresh rhythm of the display screen. It should be understood that the module for executing the above-mentioned scanning process can be composed of multiple multiplexing circuits (MUX) to improve the accuracy of the method. The description of this in the present disclosure is a description of the method at the overall level, and the present disclosure does not limit the specific implementation circuit. In addition, the dimensions for determining sampling accuracy are not limited to the above two dimensions. For example, in order to better enable the first sampling and the second sampling to be completed within the same refresh blank period, the software algorithms for the first sampling and the second sampling can be optimized, and this disclosure does not impose any restrictions on this.

[0071] In the embodiment of the present disclosure, during the current refresh blank period of the touch display screen, a first sampling with a lower number of sampling rounds or a lower number of points collected in each sampling round is first performed, and after the touch scan based on the first sampling collects an interaction event, a second sampling with a higher number of sampling rounds or a higher number of points collected in each sampling round is performed during the same refresh blank period as the first sampling. Based on this, when there is no interaction event on the screen, the first sampling with low software and hardware power consumption can be used to implement the scanning of interaction events, and once the first sampling collects an interaction event, the second sampling is immediately performed during the same refresh blank period to obtain more accurate interaction event information, thereby greatly reducing the software and hardware power consumption of the method. Compared with the solution of executing ActiveScan in the next refresh blank period after Doze Scan collects an interaction event, this method greatly improves the touch response speed, greatly improves the user experience, and achieves a balance between software and hardware power consumption and touch response speed.

[0072] In order to enable the first sampling and the possible second sampling to be completed within the same refresh blank period of the touch display screen, in some embodiments of the present disclosure, some optional methods are exemplarily provided, including the following three.

[0073] The first optional method: the touch scan is performed based on the first sample during the current refresh blank period of the touch display screen, including, in response to the touch display screen reaching the refresh blank period, performing the touch scan based on the first sample within a first duration, so that the difference between the duration of the refresh blank period and the first duration is greater than or equal to the execution duration of the touch scan based on the second sample.

[0074] In other words, in this method, the start time of the first sampling can be made close to the start time of the refresh blank period of the touch display screen, and by pre-setting the number of points collected by the first sampling in each sampling round and the number of sampling rounds, the first sampling and the possible second sampling can be completed within the first time period after the refresh blank period of the touch display screen starts.

[0075] The second optional method: in response to the touch scan based on the first sampling collecting an interaction event, performing the second sampling within the current refresh blank period of the touch display screen, including in response to the touch scan based on the first sampling collecting an interaction event, performing the second sampling within a second time period, so that the touch scan based on the second sampling is completed within the current refresh blank period.

[0076] Similarly, in this method, the start time of the second sampling can be made close to the time when the first sampling collects the interaction event, and by pre-setting the number of points collected by the second sampling in each sampling round and the number of sampling rounds, the second sampling can be completed within the second time period after the first sampling collects the interaction event, and the second sampling can be completed within the current refresh blank period.

[0077] A third optional method: in response to the touch scan based on the first sampling capturing an interaction event, a second sampling is performed within the current refresh blank period of the touch display screen, including, in response to the touch scan based on the second sampling not being completed within the current refresh blank period, extending the current refresh blank period so that the touch scan based on the second sampling is completed within the current refresh blank period.

[0078] Specifically, in response to the touch display screen being about to trigger the next refresh (for example, the touch display screen receives an instruction to trigger the next row refresh or frame refresh, or the conditions for triggering the next row refresh or frame refresh are met at the current moment) and the second sampling has not been completed, the triggering timing of the next refresh of the touch display screen can be delayed for a preset period of time, or the triggering timing can be corrected to the timing when the second sampling is completed, so that the second sampling can be completed within the same refresh blank period of the first sampling, thereby improving the touch response speed as much as possible while taking into account the power consumption of the method execution.

[0079] In some embodiments of the present disclosure, Figure 2 As shown, the method may further include:

[0080] S201: in response to the touch scan based on the second sampling capturing an interaction event, performing touch scan based on the third sampling in each refresh blank period after the touch display screen is touched;

[0081] The number of points collected by the third sampling in each sampling round is not less than the number of points collected by the second sampling in each sampling round, and / or the number of sampling rounds of the third sampling is not less than the number of sampling rounds of the second sampling.

[0082] For explanations about interactive events, refresh blank periods, number of points, and number of sampling rounds, please refer to the relevant parts in the previous text and will not be repeated here. The number of points and number of sampling rounds collected by the third sampling in each sampling round can be the same as the second sampling, or more than the second sampling. In other words, the sampling accuracy of the third sampling can be the same as the second sampling (the third sampling can also be completed directly based on the software and hardware configuration of the second sampling), or it can have a higher sampling accuracy than the second sampling. Exemplarily, when the second sampling is the usual Active Scan or a customized sampling between the Doze Scan and the Active Scan, the third sampling can be an Active Scan, or a customized sampling with the same or higher accuracy as the second sampling. In the above steps, in response to the second sampling collecting the interactive event, the third sampling is performed during the refresh blank period after the touch display screen to adapt to the user's next possible interactive operations (such as drag events, continuous click events), and while ensuring the touch response speed, improve the touch sampling accuracy.

[0083] In addition, when the first sampling or the second sampling captures the interaction event, the touch display screen can be activated (for example, an interrupt signal is sent to the control module of the touch display screen, or an interrupt signal is sent to the processor so that the processor controls the touch display screen to respond to the interaction event) to enable the touch display screen to respond to the interaction event (for example, resetting the screen off countdown, changing the refresh rate, changing the sampling accuracy of the touch sampling, etc.); an interrupt signal can also be sent to the processor so that the processor responds to the interaction event (for example, improving). This is to adapt to the user's next possible interaction operation, and while ensuring the touch response speed, the touch sampling accuracy is improved, thereby greatly improving the user experience.

[0084] In some embodiments of the present disclosure, the method may further include: Figure 3 The following steps are shown:

[0085] Step S301: In response to the fact that the touch scan based on the third sampling performed during a preset number (for example, N, where N is a positive integer) of consecutive refresh blank periods does not collect any interaction events, a touch scan based on the first sampling is performed during each refresh blank period after the touch display screen.

[0086] In other words, in step S201, after the second sampling collects an interaction event, the third sampling can be executed in the next refresh blank period (at this time, the first sampling and the second sampling can no longer be executed), so as to give the user a touch response with the highest response speed and response accuracy after detecting the user's interaction intention, thereby improving the user experience; and when the third sampling executed in a preset number of consecutive refresh blank periods collects an interaction event, it can be considered that the user has temporarily lost the interaction intention, then in the next refresh blank period, the first sampling can be executed, and after the first sampling collects the interaction event, the second sampling can be executed in the same refresh blank period (that is, re-execute the steps described in step S101, step S102 to step S201, step S301), thereby forming a complete progressive chain of "first sampling-second sampling-third sampling-return to first sampling" that is adapted to the user's interaction intention, minimizing the power consumption of the method's software and hardware, and reducing the aging speed of the screen.

[0087] In the aforementioned steps, the first sampling can be used to roughly determine the content of the user's interaction event, and the second sampling can be used to accurately determine the content of the user's interaction event. In some embodiments of the present disclosure, the first sampling can be used to determine whether the interaction event has occurred on the touch screen display, and the second sampling can be used to determine the content of the interaction event, including the coordinates of the interaction event. In other words, the first sampling can be more focused on determining whether the user currently has interaction intent, while the second sampling can be more focused on the signal-to-noise ratio of the collected samples. In extreme cases, the content of the interaction event can be determined not based on the first sampling, but only used to determine whether an interaction event has occurred (i.e., whether the user currently has interaction intent). If the user currently has interaction intent, the second sampling is immediately triggered to determine the detailed content of the interaction event initiated by the user, such as the coordinates of the interaction event and the body part corresponding to the interaction event. Based on this, the method can minimize the power consumption of software and hardware and the aging rate of related components when the user does not have interaction intent (especially in scenarios where the user does not have interaction intent for a long time, such as when watching a video), while also taking into account the touch response time after the user's interaction intent is detected, significantly improving the user experience.

[0088] The following combination Figure 4 The application diagram shown further illustrates at least one of the above embodiments. Figure 4In the example shown, the touch sampling process occurs during the frame refresh blank period, the scanning frequency of the sampling process is 100K (i.e., 10μs per scan), and the TP (Touch Panel) adopts a 1:5 scheme, that is, the screen is divided into 5 MUXs for scanning; the second sampling scans 12 rounds in each Mux, that is, the time required for the second sampling is 10μs*12 times*5(Mux)=600μs; the first sampling scans 2 rounds in each MUX, that is, the time required for the second sampling is 10μs*2 times*5(Mux)=100μs; if the hardware switching time from the first sampling to the second sampling (i.e., the configuration time of the device's hardware and software from the first sampling to the second sampling) is 200μs , the frame refresh blank period of the device is above 100μs+200μs+600μs=900μs, which can ensure that the first sampling and the possible second sampling can be completed within the same frame refresh blank period (in this case, the first duration in some of the aforementioned embodiments can be set to 100μs and the second duration can be set to 800μs). Since the frame refresh blank period is usually 1000μs to 2000μs, the above steps can greatly improve the touch response time and significantly enhance the user experience without affecting the aging speed of related components.

[0089] exist Figure 4 In the example shown in FIG, there is a gap between the start time of the first sampling and the start time of the frame refresh blank period, but this is only an exemplary description and is not limited in this disclosure. Figure 4 In the four frame refresh blank periods shown, the user places a finger on the touch screen after the second frame refresh blank period starts and before the first sampling corresponding to the second frame refresh blank period starts, thereby starting an interaction event. At this time, the first sampling corresponding to the second frame refresh blank period will collect the occurrence of the interaction event, and the second sampling will be performed in the same frame refresh blank period to determine the interaction event information with a higher signal-to-noise ratio (an interrupt signal can be sent to the processor at this time to enable the processor to respond to the interaction event, or an interrupt signal can be sent to the processor immediately after the first sampling collects the interaction event to obtain the shortest touch response time). In the third frame refresh blank period, since the first and second sampling in the second frame refresh blank period collect the interaction event, it can be assumed that the user still has the intention to interact, and the third sampling can be performed to obtain the highest sampling signal-to-noise ratio. However, since the user has removed the finger before the third sampling (the interaction event ends), the third sampling does not collect the interaction event. When the aforementioned N is set to 1, the first sampling can be performed in the fourth frame refresh blank period, and the method is executed again according to the logic of the aforementioned steps S101 and S102.

[0090] Based on experimental data, compared to executing Active during the next refresh blank period after Doze Scan detects an interaction event, this method can reduce average touch latency from 27.9ms to 11.3ms (16.6ms faster), significantly improving the user experience. For the specific details and beneficial effects of the above steps, please refer to the relevant sections of the previous embodiment and will not be repeated here.
