[0002] In daily life, touchscreens are one of the most frequently interacted devices between users and electronic devices. Touchscreens of electronic devices are often subjected to pressure, drops, or aging, which can cause damage to parts of the touchscreen.

[0003] In related technologies, when a touchscreen is damaged, users can only choose to replace the screen to ensure the touch performance of the electronic device's touchscreen and thus satisfy their own user experience. However, this approach will undoubtedly increase the user's expenses and thus increase the cost of using the electronic device. Summary of the Invention

[0016] Optionally, compensating for the capacitance value of the touch unit based on the capacitance values of the at least two target touch units includes:

[0022] Optionally, the method further includes:

In this way, based on the capacitance values of each touch unit in the non-abnormal area and the compensated capacitance values of each touch unit in the abnormal area, a reporting output can be generated. This avoids situations where the system cannot respond to touch operations performed by the user on a damaged area without replacing the screen, thus satisfying the user's preferred user experience.
[0034] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and are not intended to limit this disclosure. Attached Figure Description

[0041] Figure 6 This is a block diagram illustrating a touchscreen reporting output device according to an exemplary embodiment.
[0042] Figure 7 This is a block diagram illustrating an electronic device according to an exemplary embodiment. Detailed Implementation
[0043] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.
[0044] Figure 1 This is a flowchart illustrating a touchscreen reporting output method according to an exemplary embodiment, such as... Figure 1 As shown, the reporting output method is used in electronic devices, such as mobile phones, tablets, etc., and the reporting output method includes the following steps.
[0045] In step S101, a touch operation on the touch screen is detected. If an abnormal area exists in the touch area corresponding to the touch operation, the capacitance value of each touch unit in the abnormal area is compensated. The compensation is used to set the capacitance value of each touch unit in the abnormal area to a value that changes compared to the capacitance value of an untouched touch unit.
[0046] It should be noted that abnormal areas include touch units within the touch area whose capacitance values do not change. Therefore, the presence of abnormal areas in the touch area can be determined by whether the capacitance values of touch units within the touch area change. Specifically: a touch operation on the touchscreen is detected, and the capacitance value of each touch unit within the touch area corresponding to the touch operation is obtained; if the capacitance value of any touch unit within the touch area does not change, an abnormal area is determined to exist in the touch area corresponding to the touch operation.
[0047] by Figure 2 The diagram illustrates the capacitance values of a touchscreen with an abnormal area when touched, assuming the capacitance of untouched touch units is 0. This implies that the capacitance of touch units in the abnormal area is also 0. Figure 2 In the diagram, TX0 to TX6 represent the horizontal direction of the touchscreen, RX0 to RX15 represent the vertical direction, and the intersection of TX and RX represents the touch unit on the touchscreen, such as... Figure 2 As shown, the touch area is the area surrounded by touch units whose capacitance values change at the edge. Since the intersection of RX8 and TX4 is located within this touch area and the capacitance value of this intersection is 0, the area corresponding to this intersection is an abnormal area. This abnormal area is the area corresponding to a single point, which can easily cause sliding offset problems.
[0048] by Figure 3 The diagram shown illustrates another example of capacitance data when a touchscreen with an abnormal area is touched. Figure 3 In the diagram, TX0 to TX7 represent the horizontal direction of the touchscreen, RX0 to RX15 represent the vertical direction, and the intersection of TX and RX represents the touch unit on the touchscreen, such as... Figure 3 As shown, the touch area is the area surrounded by the touch unit whose capacitance value changes at the outermost edge. The capacitance values at the intersections of RX6 and TX4, RX7 and TX4, RX8 and TX4, and RX9 and TX4 are 0. The intersections of RX6 and TX4, RX7 and TX4, RX8 and TX4, and RX9 and TX4 are located within this touch area. That is, the area corresponding to the intersections of RX6 and TX4, RX7 and TX4, RX8 and TX4, and RX9 and TX4 is an abnormal area. This abnormal area is the area corresponding to multiple adjacent points, which can easily cause problems such as sliding breakage and sliding offset.
[0049] by Figure 2 Taking the schematic diagram as an example, if the capacitance value of the untouched touch unit is 0, then the intersection of RX8 and TX4 can be set to other values that produce a change compared to 0, such as 944.
[0050] It should be noted that the capacitance value of an untouched touch unit can be -1. In this case, the intersection of RX8 and TX4 can be set to a value that changes compared to -1, such as 944.
[0051] In step S102, a reporting point is output based on the capacitance value of each touch unit in the non-abnormal area of the touch area and the capacitance value of each touch unit in the abnormal area after compensation.
[0052] It should be noted that when there is a touch operation on the touchscreen, the capacitance value of the touch unit on the touchscreen will change. The specific location of the touch can be determined based on the magnitude of the capacitance value change. For example, the location of the touch unit with the largest capacitance value change is generally selected as the reporting location (the capacitance value of the reporting point exceeds a preset reporting threshold), and the reporting point is output. If the capacitance value of the abnormal area cannot be obtained, the correct reporting location cannot be identified.
[0053] Understandably, to avoid accidental touches, a reporting threshold can be set. The electronic device will only detect and output a report when the capacitance value of the touch unit in the touch area exceeds the reporting threshold. This disclosure describes a scheme for reporting output when a reporting threshold is set.
[0054] By monitoring touch operations on the touchscreen using the above method, if an abnormal area exists in the touch area corresponding to the touch operation, the capacitance value of each touch unit in the abnormal area is compensated. This compensation sets the capacitance value of each touch unit in the abnormal area to a value that changes compared to the capacitance value of an untouched touch unit. In this way, based on the capacitance values of each touch unit in the non-abnormal area and the compensated capacitance values of each touch unit in the abnormal area, point reporting can be performed. This avoids situations where the system cannot respond to touch operations performed by the user on a damaged area without replacing the screen, thus satisfying the user's preferred experience.
[0055] Among the possible approaches, refer to Figure 4 , Figure 1 The step of outputting a reporting point based on the capacitance value of each touch unit in the non-abnormal area of the touch region and the compensated capacitance value of each touch unit in the abnormal area may include the following steps:
[0056] In step S401, the initial reporting point is determined based on the capacitance value of each touch unit in the non-abnormal area of the touch area and the capacitance value of each touch unit in the compensated abnormal area.
[0057] It should be noted that the initial reporting point can be the location corresponding to the touch unit with the largest change in capacitance value in the touch area.
[0058] In step S402, when the initial reporting point is located in an abnormal region, multiple historical reporting points before the output initial reporting point are obtained.
[0059] For example, the location coordinates of the initial reporting point can be compared with the location coordinates of the abnormal area. If the location coordinates of the initial reporting point are within the abnormal area, it can be determined that the initial reporting point is located in the abnormal area.
[0060] For example, the number of historical reporting points can be set according to the actual situation, and this embodiment does not limit it.
[0061] In step S403, a fitting curve is determined based on multiple historical reporting points, and a predicted reporting point is obtained based on the fitting curve.
[0062] For example, a fitting curve can be determined based on the x-coordinate and y-coordinate of historical reporting points. Based on the equation corresponding to the fitting curve, the x-coordinate of the initial reporting point is substituted into the equation to determine the y-coordinate. The x-coordinate and the determined y-coordinate can then be used as the predicted reporting point.
[0063] For example, a fitting curve can be determined based on the x-coordinate and y-coordinate of the historical reporting points, resulting in two fitting curves. The x-coordinate of the predicted reporting point can be determined based on the trend of the fitting curve obtained from the fitting x-coordinate, and the y-coordinate of the predicted reporting point can be determined based on the trend of the fitting curve obtained from the fitting y-coordinate.
[0064] In step S404, the initial reported point and the predicted reported point are compared, and the initial reported point is corrected according to the comparison result, and the corrected initial reported point is output.
[0065] For example, the distances between the initial and predicted reporting points' x and y coordinates can be compared. Based on the relationship between the difference between these distances and a preset value and the preset distance (i.e., the comparison result), it can be determined whether to correct the initial reporting point. For instance, if the difference between the x and y coordinates of the initial and predicted reporting points is greater than or equal to the preset distance, the x and y coordinates of the predicted reporting point are directly replaced with the x and y coordinates of the initial reporting point to obtain the corrected x and y coordinates. Similarly, if the difference between the x and y coordinates of the initial and predicted reporting points is greater than or equal to the preset distance, the y and y coordinates of the predicted reporting point are directly replaced with the y and y coordinates of the initial reporting point to obtain the corrected y and y coordinates. Conversely, if the difference between the x and y coordinates of the initial and predicted reporting points is less than the preset distance, no coordinate replacement is performed.
[0066] Reference Figure 5 This is a schematic diagram illustrating the correction of initial coordinates. (See diagram below.) Figure 5 As shown, Figure 5 The points to the left of the predicted reporting points shown are the historical reporting points. The curve connecting the historical reporting points is the fitted curve. If the initial reporting point is used as the final reporting point, it will cause excessive jitter. Therefore, in order to make the fitted curve smoother, the predicted reporting points are predicted, and the position of the initial reporting point is corrected to the position of the predicted reporting point. This further reduces the deviation between the reporting point position and the actual operation position and improves the accuracy of the reporting points.
[0067] In the possible ways, Figure 1 The step of compensating the capacitance value of each touch unit in the abnormal region may include: for each touch unit in the abnormal region, determining at least two target touch units adjacent to the touch unit, wherein the target touch units are touch units whose capacitance values have changed; and compensating the capacitance value of the touch unit based on the capacitance values of the at least two target touch units.
[0068] by Figure 2Taking the capacitance value data shown as an example, for the touch unit represented by the intersection of RX8 and TX4, the touch unit represented by the intersection of RX8 and TX3, which is adjacent to the intersection of RX8 and TX4, and the touch unit represented by the intersection of RX8 and TX5 can be identified as the target touch unit. Furthermore, the capacitance value of the touch unit represented by the intersection of RX8 and TX4 is compensated according to the capacitance values 893 and 995 corresponding to the target touch unit.
[0069] By using the above method, since the capacitance value of the target touch unit adjacent to the touch unit in the abnormal area is the smallest difference from the capacitance value of the touch unit, selecting the capacitance values corresponding to at least two target touch units adjacent to the touch unit in the abnormal area to compensate for the capacitance value of the touch unit can ensure the accuracy of the numerical compensation.
[0070] In one possible manner, the step of compensating the capacitance value of a touch unit based on the capacitance values of at least two target touch units may include: when the abnormal area is located in the center of the touch area, compensating the capacitance value of the touch unit to a first value based on the capacitance values of at least two target touch units, wherein the first value is greater than the capacitance value of each target touch unit.
[0071] It should be noted that when the abnormal area is located in the center of the touch area, it indicates that the reporting point is most likely to occur within the abnormal area. If the reporting point is actually located in the abnormal area, and the compensation value of the touch unit in the abnormal area is lower than the preset threshold, the electronic device will experience a point loss problem, meaning that no point reporting operation will be performed.
[0072] Considering the above, the capacitance value of the touch unit in the abnormal area can be compensated to be greater than the capacitance value of each target touch unit, thereby increasing the probability of reporting a point and reducing the probability of missing a point.
[0073] In one possible manner, the step of compensating the capacitance value of a touch unit based on the capacitance values of at least two target touch units may include: when the abnormal area is located in the center of the touch area, compensating the capacitance value of the touch unit to a second value based on the capacitance values of at least two target touch units, and reducing a preset reporting threshold, wherein the second value is less than the maximum capacitance value among the at least two target touch units, and the touch unit whose capacitance value exceeds the reporting threshold is a reporting point.
[0074] Based on the same considerations, the capacitance value of the touch unit in the abnormal area can be compensated to be less than the maximum capacitance value among at least two target touch units, while the reporting threshold is lowered to increase the probability of reporting a point and reduce the probability of missing a point.
[0075] For example, the second value can be the average capacitance value of all target touch units.
[0076] In one possible approach, the method further includes: when it is determined that there is an abnormal area in the touch area corresponding to the touch operation, setting an abnormal identifier for the touch unit in the abnormal area, the abnormal identifier being used to subsequently detect touch operations on the touch screen and determine that there is an abnormal area in the touch area corresponding to the touch operation.
[0077] Understandably, if subsequent monitoring detects that the touch area corresponding to a touch operation on the touchscreen includes touch units with an abnormality flag, it can be directly determined that there is an abnormal area in the touch area corresponding to the touch operation, without needing to obtain the unit value of each touch unit in the touch area to determine whether there is an abnormal area, thus improving the efficiency of abnormal area determination.
[0078] Furthermore, it can be understood that if the touch area corresponding to the touch operation on the touchscreen is not included in the touch unit with the abnormality indicator, the presence of an abnormal area in the touch area corresponding to the touch operation can be determined by whether the capacitance value of each touch unit in the touch area corresponding to the touch operation changes.
[0079] For example, touch units with error flags can be saved in the file system to prevent the error flags from being lost after a restart.
[0080] In one possible approach, the point reporting output method can be applied to an application processor. Considering that point reporting algorithms in related technologies are all processed by touch chips, and the processing power of touch chips is relatively weak, this can lead to high latency for computationally complex algorithms. Therefore, using an application processor to execute the point reporting output method can reduce the point reporting latency.
