[0003] In actual use, the capacitance data of touch screen devices in different states and working conditions will be different. For example, in the charging state, the noise introduced by the charger will cause the capacitance data to be different from the capacitance data in the non-charging state. If the capacitance data in the non-charging state is still used, it will lead to inaccurate touch sampling, jitter in the sliding point reporting, and then jitter in the screen.

[0026] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0027] It should be understood that the various steps described in the method embodiments of the present disclosure may be performed in different orders and / or in parallel. In addition, the method embodiments may include additional steps and / or omit the steps shown. The scope of the present disclosure is not limited in this respect.

[0028] The term "including" and its variations used herein are open inclusions, i.e., "including but not limited to". The term "based on" means "based at least in part on". The term "one embodiment" means "at least one embodiment"; the term "another embodiment" means "at least one additional embodiment"; the term "some embodiments" means "at least some embodiments". The relevant definitions of other terms will be given in the following description.

[0029] In the related art, the function of the touch screen is realized based on the principle of capacitive sensing. When the user touches the screen, the touch screen recognizes the coordinates of the object, and then calculates the capacitance difference between the current object touching the touch screen and not touching the touch screen. By determining whether the capacitance difference is within the preset reporting threshold, the point is reported when it is within the reporting threshold. However, since the capacitance data of the touch screen varies in different states and working conditions, the reporting of points in different states varies.

[0030] For example, in the charging state, due to the noise introduced by the charger interference, the capacitance data at this time is different from the capacitance data in the non-charging state, which in turn affects the accuracy of touch sampling, causing the sliding point reporting to jitter, and then causing the screen to jitter.

[0031] Therefore, there is an urgent need for a method that can avoid the occurrence of report point jitter and cause the screen jitter of the touch screen to improve the accuracy of touch sampling.

[0032] In order to solve the technical problems existing in the related art, the present application embodiment provides a touch sampling method in a charging state, see Figure 1 , Figure 1 1 is a flow chart of a touch sampling method in a charging state provided in an embodiment of the present application. The method includes steps 101 to 104.

[0033] Step 101: Acquire first charging information of a terminal currently monitored, and acquire second charging information of a terminal monitored in an adjacent previous time.

[0034] In one embodiment, when the terminal is in a charging state, the charging state of the terminal may be monitored to obtain first charging information currently monitored, and simultaneously obtain second charging information obtained when monitoring was performed at an immediately previous moment.

[0035] For example, when the terminal is charging, the charging power will change as the charging continues. For example, the charging power is different when fast charging is performed at a low power level and when slow charging is performed at a high power level. Another example is using chargers with different charging powers or using different charging methods. Different chargers and charging methods have different effects on the noise of the touch screen. Therefore, at this time, the filter coefficient during touch sampling is dynamically adjusted according to the actual charging status and charging information to improve the timeliness and accuracy of touch sampling and avoid screen jitter due to report point jitter.

[0036] In actual applications, when the terminal is charging, the charging status of the terminal may be monitored periodically to obtain corresponding charging information when the monitoring is completed. Specifically, a certain time interval may be set as the monitoring time interval.

[0037] Step 102: Compare the first charging information with the second charging information to determine a current filter coefficient of the terminal.

[0038] In one embodiment, after monitoring the current first charging information of the terminal and obtaining the second charging information, the first charging information and the second charging information are compared and analyzed to determine the filter coefficient for touch sampling at the current moment. Specifically, when comparing the first charging information and the second charging information, it is determined whether the charging state of the terminal has changed. If it is determined that a change has occurred, the filter coefficient needs to be adjusted in time, and if no change has occurred, the filter coefficient can be kept unchanged.

[0039] For example, when comparing the first charging information with the second charging information to determine the current filter coefficient of the terminal, reference may be made to Figure 2 , Figure 2 1 is a flow chart of the steps of determining the filter coefficients provided in an embodiment of the present application, wherein the steps include steps 201 to 203.

[0040] Step 201, comparing the first charging information with the second charging information to determine whether the charging state of the terminal has changed;

[0041] Step 202, when it is determined that the charging state of the terminal has changed, query in a preset list according to the first charging information to determine whether there is a matching filter coefficient for the first charging information, wherein the preset list records the corresponding relationship between the charging information and the filter coefficient;

[0042] Step 203: When it is determined that there is a matching filter coefficient, the filter coefficient corresponding to the first charging information is obtained.

[0043] In one embodiment, when comparing the first charging information with the second charging information, it is determined whether the two are the same, and then whether the charging state of the terminal has changed. When it is determined that the charging state has changed, the filter coefficient is determined according to the current charging state of the terminal. Specifically, the first charging information is used to query in a preset list to determine whether there is a filter coefficient that matches the first charging information. When it is determined that there is, the filter coefficient corresponding to the first charging information is directly obtained as the current filter coefficient of the terminal.

[0044] The preset list records the corresponding relationship between the charging information and the filter coefficient. Each set of charging information corresponds to a filter coefficient, and the charging information at least includes the charging power and the charging mode.

[0045] Specifically, when comparing the first charging information and the second charging information, by comparing the charging power and the charging mode at the same time, it is determined that the charging state of the terminal has not changed only when all the information is the same, and as long as there is a difference, it means that the charging state of the terminal has changed.

[0046] Exemplarily, the charging information of the terminal records the charging mode and charging power of the terminal, wherein the charging mode includes wired charging and wireless charging, and the charging power is the actual power during charging. The information recorded in the preset list may be as shown in Table 1 below.

[0047] Table 1

[0048]

[0049] It can be seen from Table 1 that different filter coefficients are set for different charging information. Therefore, when making a comparison, it is determined whether the filter coefficient needs to be adjusted by comparing the charging mode and the charging power.

[0050] When it is determined that the filter coefficient needs to be adjusted, that is, the first charging information and the second charging information are different, the filter coefficient will be queried in the preset list according to the first charging information, and a one-to-one comparison will be performed according to the charging information to find the filter coefficient corresponding to the first charging information.

[0051] Furthermore, when comparing the first charging information with the second charging information to determine whether the charging status has changed, if it is determined that the charging status has not changed, the filter coefficient can be kept unchanged, specifically including: when it is determined that the charging status of the terminal has not changed, the filter coefficient when the terminal is charged based on the second charging information is used as the current filter coefficient of the terminal.

[0052] In actual applications, in order to achieve reasonable adjustment, when it is determined that the charging state of the terminal has not changed, a corresponding judgment can also be made to determine whether to make an adjustment. For example, when it is determined that the charging state has not changed, it is determined whether the filter coefficient corresponding to the second charging information exists in the preset list. If it is determined that it exists, no further judgment is required, and if it is determined that it does not exist, further judgment is performed.

[0053] It should be noted that in actual applications, there will be a certain fluctuation in the charging power in the charging information, and when setting the filter coefficients corresponding to different charging information, they are not listed one by one. There may be a situation where the charging information has no corresponding filter coefficient. Therefore, at this time, when it is determined that the charging modes are the same, the charging powers in the first charging information and the second charging information can be analyzed to determine whether the floating values ​​of the two are less than the set values, and then when it is determined that they are less than the set values, it is determined that the charging state of the terminal has not changed. That is, each filter coefficient can correspond to a charging power range.

[0054] When it is determined that the charging status has changed and there is no filter coefficient corresponding to the second charging information in the preset list, in addition to directly using the filter coefficient when the terminal charges based on the second charging information, appropriate adjustments can also be made by calculating the difference between each charging power in the preset list and the charging power in the first charging information and the second charging information, and selecting the filter coefficient corresponding to a nearby charging power (corresponding to one charging information) as the current filter coefficient.

[0055] Further, when it is determined that the charging state of the terminal has not changed, but the filter coefficient corresponding to the first charging information is not found in the preset list, it is necessary to make an independent selection to determine the current filter coefficient of the terminal, such as, when it is determined that there is no matching filter coefficient, keep the filter coefficient of the terminal in the charging state corresponding to the second charging information unchanged. That is, when there is no filter coefficient corresponding to the first charging information in the preset list, keep the filter coefficient unchanged, that is, determine the current filter coefficient as the filter coefficient corresponding to the terminal when charging based on the second charging information.

[0056] In addition to keeping the filter coefficient unchanged, the filter coefficient can also be selected from the preset list according to the first charging information. For details, please refer to Figure 3 , Figure 3 This is another flowchart diagram of the step of determining the current filter coefficient provided in an embodiment of the present application, wherein the step includes steps 301 to 304.

[0057] Step 301, when it is determined that there is no matching filter coefficient, obtaining a charging mode and a charging power of first charging information;

[0058] Step 302, filtering the preset list according to the charging mode to obtain a first set;

[0059] Step 303, obtaining the charging power corresponding to each filter coefficient in the first set, and performing difference calculation with the charging power of the first charging information to obtain a power difference;

[0060] Step 304: Select a filter coefficient from the first set according to the power difference as the current filter coefficient of the terminal.

[0061] Exemplarily, when it is determined that there is no filter coefficient matching the first charging information, the charging mode and charging power contained in the first charging information are obtained, and the charging mode and charging power are first filtered out in a preset list based on the charging mode to obtain a first set, wherein the charging mode corresponding to the filter coefficient contained in the first set is the same as the charging mode of the first charging information, and then the charging power corresponding to each filter coefficient in the first set is calculated to differ from the charging power of the first charging information to obtain the power difference, and then a filter coefficient is selected in the first set according to the power difference as the current filter coefficient of the terminal.

[0062] In actual processing, the charging modes of the terminal are divided into two modes: wired charging and wireless charging. However, there are many charging powers, which can be exhaustively listed according to actual needs. Therefore, when processing, a screening is performed based on the charging mode, and then a secondary screening and determination is performed using the charging power.

[0063] After completing a screening according to the charging mode, a first set with the same charging mode is obtained, and then the difference in charging power with the first charging information is calculated, and when selecting according to the power difference, the filter coefficient corresponding to the smallest power difference is selected as the current filter coefficient of the terminal. That is, when determining the current filter coefficient according to the power difference, it includes: comparing the power difference with the preset difference threshold, and screening the first set according to the comparison result to obtain the second set, wherein the power difference corresponding to each filter coefficient in the second set is less than the preset difference threshold; and selecting the filter coefficient corresponding to the smallest power difference in the second set as the current filter coefficient of the terminal.

[0064] In addition, when constructing a preset list, a function method can be used to determine the correspondence between different charging powers and filter coefficients in the same charging mode, such as obtaining a function correspondence between different charging powers and filter coefficients in a wired charging mode. When it is determined that the charging state has changed, the current filter coefficient can be determined according to the function correspondence, thereby completing real-time adjustments. Of course, when determining and adjusting the filter coefficient based on this method, a power floating range can also be set. When the difference between the current charging power and the charging power monitored in the previous adjacent time is within the set floating range, the same filter coefficient can be used, that is, the filter coefficient is kept unchanged, that is, the corresponding relationship between the charging power and the filter coefficient at this time is a step-like curve relationship.

[0065] It should be noted that when the terminal is in a non-charging state, a default filter coefficient can be set for it so that the terminal uses the default filter coefficient for touch sampling when it is in a non-charging state. At the same time, when it is detected that the terminal changes from a charging state to a non-charging state, the current filter coefficient of the terminal will be adjusted to the default filter coefficient.

[0066] Step 103, obtain the scanned first coordinate, second coordinate and third coordinate, wherein the first coordinate is the coordinate of the target touch point currently scanned, the second coordinate is the coordinate of the target touch point scanned in the previous scan adjacent to the current scan, and the third coordinate is the coordinate of the target touch point scanned in the previous scan adjacent to the previous scan.

[0067] In one embodiment, when performing touch sampling, it is necessary to determine the current touch point and perform point reporting processing, so it is necessary to accurately determine the coordinates of the current touch point after the adjustment of the filter coefficient is completed. When determining the coordinates of the current touch point, the scanned first coordinate, second coordinate and third coordinate are obtained, wherein the first coordinate is the coordinate of the target touch point currently scanned, the second coordinate is the coordinate of the target touch point scanned in the previous scan adjacent to the current scan, and the third coordinate is the coordinate of the target touch point scanned in the previous scan adjacent to the previous scan, so as to determine the current coordinates according to the acquired coordinate information.

[0068] Step 104 , calculating a fourth coordinate representing the current touch sampling result of the terminal according to the filter coefficient, the first coordinate, the second coordinate and the third coordinate, and reporting the first coordinate, the second coordinate, the third coordinate and the fourth coordinate.

[0069] In one embodiment, after obtaining the relevant coordinate information obtained by scanning, the coordinates of the current point to be reported are determined according to the current filter coefficient of the terminal, combined with the first coordinate, the second coordinate and the third coordinate, and then the first coordinate, the second coordinate, the third coordinate and the fourth coordinate are reported. In fact, the first coordinate, the second coordinate and the third coordinate are the coordinates of the reported point.

[0070] Exemplarily, when calculating to obtain the fourth coordinate, a weighted average algorithm may be used for calculation. Specifically, when performing the calculation, the coordinates of the reported point are calculated as follows.

[0071]

[0072]

[0073] Among them, the coordinates (x1, y1) are the real coordinates of the current scan, the coordinates (x2, y2) are the coordinates of the last scan, the coordinates (x3, y3) are the coordinates of the last scan, the coordinates (x0, y0) are the coordinates of the current reporting point, A, B, C are the filter coefficients, and A+B+C=15. Of course, the filter coefficients can be set according to the actual situation.

[0074] When reporting points based on the above method, when A is larger, it means that the current coordinate accounts for a larger proportion, so the reporting response is faster and the jitter is more serious. When A is smaller, it means that the current coordinate accounts for a smaller proportion, so the reporting response is slower, the reporting lag is serious, and the jitter is weaker.

[0075] When adjusting the filter coefficient, it is necessary to ensure that the reporting point response is timely and the reporting point jitter is avoided, so that the touch sampling has better timeliness and accuracy without the reporting point jitter.

[0076] Further, refer to Figure 4 , Figure 4 This is a block diagram of a touch sampling system provided by an embodiment of the present application, wherein the system includes a touch screen system and a terminal system, and the touch screen system includes a memory and a processor, and the terminal system acquires data in the touch screen system through an interrupt signal triggered by an INT pin. The terminal system sets the touch screen system through a 2C SPI interface.

[0077] Based on Figure 4 When the system shown implements touch sampling in the charging state, the touch sampling process can refer to Figure 5 , Figure 5 is a schematic diagram of a block diagram of a touch sampling method in a charging state provided by an embodiment of the present application. Figure 5 In the block diagram shown, the charging information is determined based on the charger and the charging method. Different chargers have different corresponding charging powers. Figure 5 When describing, the difference in chargers indicates the difference in charging power.

[0078] Specifically, a correspondence table of different charging modes and charging powers and the filter coefficients of the touch screen is preset in the terminal system, where the correspondence table can be as shown in Table 1 above, and then the charging status is detected through a monitoring service, such as using an interrupt polling scheme to monitor the charging status. When it is detected that the current charger type is different from the previous one, it is determined whether the currently updated charger has a preset touch screen filter coefficient threshold. If so, the touch screen module is notified to adjust the filter coefficient. If not, no notification is made, that is, no adjustment is made. Then, the touch screen driver of the terminal system sets corresponding instructions to the touch screen system according to the received notification.

[0079] Finally, the touch screen system adjusts the filter coefficient according to the notification sent by the terminal system. For example, when receiving the first threshold command of the terminal system to enlarge, it switches to the first threshold system (corresponding to a filter coefficient), or according to the second or third / fourth threshold command sent by the terminal system, it switches to the second or third / fourth threshold system, where the number of filter coefficients corresponds to the number of threshold systems. After the system switching is completed, the reporting point processing is completed according to the filter coefficient of the switched system, and the charging status of the terminal will still be monitored.

[0080] In summary, the present application discloses a touch sampling method in a charging state. When a terminal in a charging state performs touch sampling, the charging state of the terminal is monitored and processed to obtain the current first charging information of the terminal currently monitored, and the second charging information monitored in the adjacent previous time is obtained. When there are corresponding filter coefficients in the second charging information, the current filter coefficient of the terminal is determined according to the first charging information and the second charging information, so that the terminal can adjust the filter coefficient in time when the charging state changes, and then obtain the first coordinate currently scanned, the second coordinate scanned in the previous time, and the third coordinate scanned in the previous time, calculate according to the adjusted filter coefficient, obtain the fourth coordinate, and finally upload all the obtained coordinates to complete the touch sampling. When the mobile terminal is in a charging state, the influence of charging on touch sampling is added to the touch sampling, and the filter coefficient is adjusted in real time according to the charging state to avoid the occurrence of point jitter and screen jitter, thereby improving the accuracy of touch sampling.

[0081] According to the method described in the above embodiment, this embodiment will be further described from the perspective of a touch sampling device in a charging state. The touch sampling device in a charging state can be implemented as an independent entity or integrated in an electronic device, such as a terminal. The terminal may include a mobile phone, a tablet computer, etc.
