[0046] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same 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 disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0047] In the related art, in order to improve the water-operating performance of the touch screen, the touch screen is detected and judged in real time whether it has entered the wet water mode. When it is determined that it has entered the wet water mode, it is judged whether the signal is a water signal. If it is a water signal, the signal strength is suppressed. Since the processing of the water signal is based on the wet water mode, the accuracy of the judgment of whether the touch screen has entered the wet water mode is particularly important: if the wet water mode judgment threshold is too high, the touch screen will not be judged as the wet water mode when a small amount of water stains appear, resulting in the water signal not being suppressed in time, and problems such as coordinate jitter and touch screen malfunction when the finger touches; if the wet water mode judgment threshold is too low, it is easy to cause other touch scenes to be mistakenly judged as wet water mode, causing the finger touch signal to be mistakenly suppressed during finger operation, and the touch screen will not respond. In order to ensure the accuracy of the wet water mode judgment, a more complex algorithm is usually required, and the judgment time is long. Therefore, in actual applications, the problem of wet water mode detection lag usually occurs, resulting in untimely water signal suppression processing, or finger touch signal is mistakenly suppressed, making the actual use experience of the wet water operation scene not very good.

[0048] In an exemplary embodiment of the present disclosure, in order to overcome the problems existing in the related art and improve the water-operating performance of the touch screen, a signal processing method is provided, including: if there is an overlapping area between the first touch area and the second touch area, and the number of the first touch area is greater than the number of the second touch area, determining that the second touch area is split into the first touch area at the first moment; at the first moment, determining that there is a water signal in the first touch area, and suppressing the water signal in the first touch area; wherein the first touch area is the touch area at the first moment, the second touch area is the touch area at the second moment, the first moment is later than the second moment, the first touch area and the second touch area are areas formed by adjacent sensing points that meet preset conditions, and the water signal is a signal generated by water on the touch screen. The method can accurately and real-timely know that there is a water signal in the touch area, and suppress the water signal in time to avoid problems such as touch screen point jitter, touch screen non-response, and touch screen self-operation caused by the water signal, improve the water-operating performance of the touch screen, and enhance the user experience.

[0049] In an exemplary embodiment of the present disclosure, a signal processing method is provided. Figure 1 is a flow chart of a signal processing method according to an exemplary embodiment. Figure 1 As shown, the following steps are included:

[0050] Step S101, if there is an overlapping area between the first touch area and the second touch area, and the number of the first touch areas is greater than the number of the second touch areas, determining that the second touch area is split into the first touch area at a first moment;

[0051] Step S102, at a first moment, determining that there is a water signal in the first touch area, and suppressing the water signal in the first touch area;

[0052] Among them, the first touch area is the touch area at the first moment, the second touch area is the touch area at the second moment, the first moment is later than the second moment, the first touch area and the second touch area are areas formed by adjacent sensing points that meet preset conditions, and the water signal is a signal generated by water on the touch screen.

[0053] The method in the disclosed embodiment is applied to electronic devices, including electronic devices with touch screens, such as smart phones, tablet computers, personal computers, smart screens, smart car systems, and smart home devices. The method in the disclosed embodiment can be used as a default function of the electronic device, or as an optional function of the electronic device, such as setting a switch option of the function in the setting options related to the display screen of the electronic device, and prompting the user that the function is used to suppress water signals and optimize the touch experience. The user can turn on or off the function according to the needs, or automatically turn off the function when the electronic device turns on the low power consumption mode, so as to reduce the power consumption of the electronic device by turning off the function in certain scenarios.

[0054] In step S101, the first moment is later than the second moment, and the second moment and the first moment may differ by one frame or multiple frames. For example, the first moment is the current frame, and the second moment is the previous frame of the current frame. The touch area in the touch screen is detected in real time. The touch area is a connected area. The connected area is an area formed by adjacent sensing points that meet preset conditions. The signal value of each sensing point in the display screen is obtained. If the signal values ​​of adjacent sensing points all meet the preset conditions, the connected sensing points form a connected area, and the touch screen area occupied by the connected area is the touch area. Among them, the preset condition is an empirical value, for example, the preset condition is that the signal value is greater than the first set value and the signal gradient is greater than the second set value. It should be noted that when detecting the touch area in the display screen, there is no need to consider whether the signal generating the touch area has a water signal. The touch area in the touch screen detected at the first moment is the first touch area, and the touch area detected at the second moment is the second touch area.

[0055] When a user uses a finger or a stylus to perform a water-sliding operation, the finger and water will inevitably separate during the sliding process, that is, a portion of the water will inevitably separate from the finger during the sliding process, and residual water stains will appear after the sliding. Therefore, if the touch area in the display screen at the second moment is the touch area generated at the beginning of the water-sliding operation, and the touch area is split during the sliding process, then at the first moment, there will be a first touch area obtained by splitting the second touch area in the display screen at the second moment, that is, the residual water stain touch area at the end of the sliding and the touch area at the end of the water-sliding operation. At this time, the number of first touch areas is greater than the number of second touch areas. In addition, since the first touch area is formed during the sliding process, and the time interval between the first moment and the second moment is very short, the sliding range is very small, so there is an overlapping area between the first touch area and the second touch area.

[0056] Therefore, if there is an overlapping area between the first touch area and the second touch area, and the number of first touch areas is greater than the number of second touch areas, it can be determined that the second touch area is split into the first touch area at the first moment; if the above conditions are not met, it means that the second touch area is not split into the first touch area at the first moment, and the first touch area may be a newly added touch area or a touch area without water. In this case, it is necessary to continue tracking the changes of the first touch area at the next moment.

[0057] In one example, Figure 2A is a schematic diagram showing a second touch area according to an exemplary embodiment. Figure 2A As shown, the numerical value in the figure is the signal value of each sensing point, and the touch area therein is detected with the signal value greater than 100 and the gradient greater than 3 / 4 as the preset conditions. The area in the figure represents the second touch area detected at the second moment, and the number of the second touch area is 1. Figure 2B is a schematic diagram of a first touch area according to an exemplary embodiment. Figure 2B As shown, the numerical value in the figure is the signal value of each sensing point, and the touch area is detected with the signal value greater than 100 and the gradient greater than 3 / 4 as the preset conditions. The area in the figure represents the first touch area detected at the first moment. The number of the first touch areas is 3, which are respectively composed of 243 and 221, 391, 727, 661, and 347, and 475, 669, 217, 293, 786, 806, 665, and 172. Among them, each first touch area has an overlapping area with the second touch area, and the number of the first touch areas is greater than the number of the second touch areas, then it is determined that the second touch area is split into the first touch area at the first moment.

[0058] In step S102, the signal generated by water is a water signal. At the first moment, it is detected whether there is a water signal in the first touch area. If a water signal is detected in the first touch area, it is marked as an abnormal touch area, and the water signal therein is suppressed. According to the description of the above-mentioned touch area splitting phenomenon, if it is determined that the first touch area is obtained by splitting the second touch area, it is determined that there is a water signal in the second touch area, and the first touch area is generated by sliding with water, so there is a high probability of a water signal in the first touch area. At this time, when further detecting whether there is a water signal in the first touch area, it can be quickly known whether there is a water signal in the first touch area at the current moment, and the confidence of the detected water signal is high. When it is determined that there is a water signal, the water signal in the first touch area is suppressed in time, for example, the signal value of each sensing point in the first touch area is reduced; if it is determined that there is no water signal in the first touch area, there is no need to process the touch area.

[0059] It should be noted that, at the current moment, if the detected touch area is not a touch area split from the touch area at the previous moment, but it is determined that there is a water signal in the touch area, then the water signal in the touch area also needs to be suppressed. For example, at the first moment, if the first touch area is not obtained by splitting the touch area at the previous moment, and it is determined that there is a water signal in the first touch area, then the water signal in the first touch area also needs to be suppressed at the first moment.

[0060] In an exemplary embodiment of the present disclosure, by determining that the touch area at the current moment is obtained by splitting the touch area at the previous moment, the accuracy of water signal detection in the first touch area can be improved, and the water signal detection speed can be improved. Therefore, it is possible to know in real time and accurately whether there is a water signal in the first touch area, and to suppress the water signal in time when the water signal is detected, so as to avoid problems such as touch screen point jitter, touch screen unresponsiveness and touch screen self-operation caused by water signals, thereby improving the water operation performance of the touch screen and enhancing the user experience.

[0061] In an exemplary embodiment of the present disclosure, a signal processing method is provided. Figure 3 is a flow chart of a signal processing method according to an exemplary embodiment. Figure 3 As shown, the following steps are included:

[0062] Step S301, if there is an overlap between the first touch area and the second touch area, and the number of the first touch areas is greater than the number of the second touch areas, determining that the second touch area is split into the first touch area at the first moment;

[0063] Step S302, at a first moment, determining that there is a water signal but no touch signal in the first touch area, and suppressing the water signal in the first touch area;

[0064] Among them, the first touch area is the touch area at the first moment, the second touch area is the touch area at the second moment, the first moment is later than the second moment, the first touch area and the second touch area are areas formed by adjacent sensing points that meet preset conditions, and the water signal is a signal generated by water on the touch screen.

[0065] The specific implementation of step S301 refers to step S101 and will not be repeated here.

[0066] In step S302, the touch signal represents a signal for user input such as a finger signal or a stylus signal. It is detected whether there is a touch signal in the first touch area. If there is no touch signal in the first touch area, it means that there is only a water signal in the first touch area. At this time, the water signal in the first touch area is suppressed to avoid problems such as self-operation of the touch screen caused by the water signal. If there is a touch signal in the first touch area, adding the water signal on the basis of the touch signal will not affect the input of the touch signal. At this time, there is no need to suppress the water signal in the first touch area.

[0067] In some possible implementations, based on a first preset algorithm, it is determined that there is a water signal in the first touch area; based on a second preset algorithm, it is determined that there is no touch signal in the first touch area; wherein the first preset algorithm and the second preset algorithm are target detection algorithms.

[0068] The first preset algorithm and the second preset algorithm may be the same or different. The first preset algorithm and the second preset algorithm are both any of the target detection algorithms. In order to quickly obtain the detection result, a target detection algorithm with fast calculation speed, such as a clustering algorithm, may be used.

[0069] In some possible implementations, the similarity between every two sensing points in the first touch area is determined, and all sensing points in the first touch area are clustered according to the similarity to determine that there is a water signal but no touch signal in the first touch area.

[0070] When both the first preset algorithm and the second preset algorithm are clustering algorithms, the similarity between the signal values ​​of every two sensing points in the first touch area is calculated, and the similarity calculation method is a method that can distinguish between water signals and touch signals. According to the calculated similarity, the signal values ​​of all sensing points in the first touch area are clustered to determine whether there is a water signal and a touch signal in the first touch area, thereby determining the first touch area where there is a water signal and no touch signal.

[0071] In the embodiment of the present disclosure, suppression processing is performed on the first touch area where only the water signal exists, so as to achieve the technical effect of avoiding the problems of touch screen point jitter, touch screen unresponsiveness and touch screen self-operation caused by the water signal, thereby reducing the processing time and being able to further improve the processing speed.

[0072] In an exemplary embodiment of the present disclosure, a signal processing method is provided. Figure 4 is a flow chart of a signal processing method according to an exemplary embodiment. Figure 4 As shown, the following steps are included:

[0073] Step S401, if there is an overlap between the first touch area and the second touch area, and the number of the first touch areas is greater than the number of the second touch areas, determining that the second touch area is split into the first touch area at the first moment;

[0074] Step S402, at a first moment, determining that there is a water signal in the first touch area, and suppressing the water signal in the first touch area;

[0075] Step S403, at a third moment, if it is determined that there is a water signal in the first touch area, suppressing the water signal in the first touch area, the third moment is later than the first moment;

[0076] Among them, the first touch area is the touch area at the first moment, the second touch area is the touch area at the second moment, the first moment is later than the second moment, the first touch area and the second touch area are areas formed by adjacent sensing points that meet preset conditions, and the water signal is a signal generated by water on the touch screen.

[0077] The specific implementation of step S401-step S402 refers to step S101-step S102, which will not be repeated here.

[0078] In step S403, the third moment is later than the first moment, and the time interval between the third moment and the first moment and the time interval between the second moment and the first moment may be the same or different, for example, the first moment is the current frame, and the third moment is the next frame of the current frame. Whether there is a water signal in the first touch area is re-detected at the third moment to ensure the accuracy of the suppression process. If there is still a water signal at the third moment, the water signal in the first touch area still needs to be suppressed to ensure that the input of the touch screen is not affected by the water signal.

[0079] In some possible implementations, at the third moment, if it is determined that there is a water signal but no touch signal in the first touch area, the water signal in the first touch area is suppressed.

[0080] At the third moment, whether there is a touch signal in the first touch area is detected again. If there is no touch signal, the water signal in the first touch area is suppressed; if there is a touch signal, there is no need to suppress the water signal in the first touch area. The detection method of the water signal and the touch signal is the same as the detection method at the first moment.

[0081] In some possible implementations, at the third moment, if it is determined that the first touch area satisfies at least one of the following two conditions, no processing is performed on the first touch area:

[0082] There is no water signal;

[0083] Split into additional touch areas.

[0084] If it is determined at the third moment that there is no water signal in the first touch area, it means that the water signal disappears, and the water stains on the touch screen may be wiped off. At this time, the mark of the abnormal touch area of ​​the first touch area is cancelled, and the first touch area is no longer processed. If the first touch area is split into other touch areas at the third moment, the first touch area disappears at the third moment, and a new touch area is detected. At this time, the mark of the abnormal touch area of ​​the first touch area is cancelled, and the first touch area is no longer processed.

[0085] In one example, Figure 5A and 5B is a schematic diagram showing the first touch area at the third moment according to an exemplary embodiment. Figure 5A As shown, at the third moment, the first touch area includes backup water frame ①, backup water frame ② and backup water frame ③, and each backup water frame in the first touch area is re-detected to see whether there is a water signal and a touch signal, and it is determined that there is a water signal but no touch signal in backup water frame ①, no signal in backup water frame ②, and there is a water signal and a touch signal in backup water frame ③. At this time, the mark of backup water frame ② is cancelled, and the following is obtained: Figure 5B The schematic diagram of the first touch area is shown, and the water signal in the backup water frame ① is suppressed.

[0086] It should be noted that step S401-step S402 in this embodiment can be replaced by step S201-step S202 to form a new embodiment.

[0087] In an exemplary embodiment of the present disclosure, a signal processing method is provided. Figure 6 is a flow chart of a signal processing method according to an exemplary embodiment. Figure 6 As shown, the following steps are included:

[0088] Step S6-1, traversing the position information of the touch frame of the previous frame (i.e., the second touch area) to detect whether a frame removal event occurs between frames;

[0089] If the touch frame of the previous frame (i.e., the second touch area) overlaps with the touch frame of the current frame (i.e., the first touch area), and the number of touch frames in the current frame is greater than the number of touch frames in the previous frame, it is determined that an inter-frame de-frame event occurs;

[0090] If an inter-frame de-framing event occurs, execute step S6-2; if an inter-frame de-framing event does not occur, execute step S6-4;

[0091] Step S6-2, performing a water feature detection on the signal frame obtained by de-framing to determine whether there is a water signal in the signal frame obtained by de-framing;

[0092] If it is determined that the frame has a wet water signal, execute step S6-3; if it is determined that the frame does not have a wet water signal, execute step S6-4;

[0093] Step S6-3, marking the frame information as a water frame, backing up the water frame, and the water frame is a newly added water frame;

[0094] Step S6-4, traverse all backup water frames to detect whether there is still a wet water signal in the backup water frame area;

[0095] Detect the newly added backup water frame and the original backup water frame at the same time;

[0096] If there is a wet water signal in the backup water frame area, execute step S6-5; if there is no wet water signal in the backup water frame area, execute step S6-6;

[0097] Step S6-5, updating water frame information;

[0098] Step S6-6, releasing water frame information;

[0099] Step S6-7, using the updated backup water frame information to perform a frame filtering operation, and suppressing the signal frame with a wet water signal but no touch signal.

[0100] The signal frame represents the touch area, and the wet water signal represents the signal generated by water.
