[0044] 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.

[0045] The touch signal control method provided by the embodiment of the present disclosure is applied to a terminal with a touch screen, wherein the touch screen may be an organic electroluminesence display (OLED) or a liquid crystal display (LCD).

[0046] In the related technology, terminals mostly use mutual capacitance detection architecture. When the finger touches the touch sensing layer, according to the principle of mutual capacitance, when the grounding conditions between the human body and the mobile phone are not good, the suspension effect is enhanced and the change in capacitance caused by the finger becomes smaller. And the more fingers there are and the larger the area, the stronger the suspension effect. In this way, the touch signal generated by clicking the terminal touch screen is unstable and jitter may occur. When the grounding is not good due to the handheld terminal, the suspension effect is large. The larger the contact area of ​​the finger, the stronger the suspension effect, resulting in different fingers showing reduced or negative values, causing points to disappear, points to be removed, jitter, etc. The suspension effect will be enhanced after the screen saver is applied to the mobile phone and when the user uses a protective case. If the mobile phone has a thick protective case, a protective film, or is placed on a desktop and other places where the hand is not holding (not directly touching the mobile phone), the common ground will be unstable and the finger signal amount (that is, the mutual capacitance signal value) will also be very different. For example Figure 1A and Figure 1B The figure shows the mutual capacitance signal value generated by touch operation under suspension conditions and non-suspension conditions. The single-finger test sensitivity is not as high as the non-suspension sensitivity. There is a probability of jitter or point removal or point elimination when two or more fingers are suspended and clicked coaxially. The mobile phone and the human body have a poor co-grounding effect. When multi-finger sliding is performed, the signal of the same finger will change when it is coaxial or non-coaxial, and the change is unstable, the coordinates are unstable, and the screen shakes. Multi-finger operation is often used in game scenes, such as finger touch operation to control the field of view key, long press shooting operation in the battlefield of excitement, and moving field of view operation. However, if the reporting point is unstable, the screen will shake when playing games, resulting in a very poor user experience.

[0047] When the phone and the human body share a good common ground, the finger signals on the screen have little impact on each other under multi-finger operation. When the phone and the human body share a poor common ground, the finger signals will vary greatly under different suspension levels (such as different thickness of case / film / on the desktop, etc.). Figure 1A and Figure 1B shown.

[0048] The mobile phone and the human body have a poor co-grounding effect, and when multiple fingers are sliding, the signal of the same finger will change when they are coaxial or non-coaxial, and the change is unstable. Figure 2A and Figure 2B , the data on both sides of the peak value (peak value) when not coaxial will change in proportion when coaxial, and there will be a probability that two peaks will appear at the finger position, which will cause the calculated touch point coordinates to be different, or even two coordinates to be calculated. When the human body and the mobile phone do not share the same ground, the coordinates calculated based on the signal amount during mobile phone games are unstable, resulting in screen jitter. For example, when the calculated coordinates are easy to change or a single point is split into two points, the human eye will perceive it, resulting in screen jitter or even screen movement.

[0049] In view of this, in order to optimize the unstable reporting when two fingers are close together, the screen shakes abnormally in the game mode. The actual size of the multi-finger signal will be affected by multiple factors under suspension, resulting in unstable reporting. The disclosed embodiment provides a touch signal control method. When it is detected that the touch operation is a multi-finger operation and meets the coaxial proximity condition, the self-capacitance signal value corresponding to the touch operation is used to compensate the mutual capacitance signal value to improve the screen jitter caused by the unstable reporting of the coaxial operation under suspension conditions.

[0050] Figure 3 is a flow chart of a touch signal control method according to an exemplary embodiment. Figure 3 As shown, the touch signal control method is used in a terminal and includes the following steps.

[0051] In step S11 , a touch operation is detected.

[0052] In step S12, when it is detected that the touch operation is a multi-finger operation and the coaxial proximity condition is met, the mutual capacitance signal value is compensated by using the self-capacitance signal value corresponding to the touch operation.

[0053] The touch screen uses self-capacitance and mutual capacitance scanning to determine the touch signal. The number of self-capacitance scanning channels is relatively small (X+Y), and the change in finger signal is relatively stable compared to the self-capacitance signal. Therefore, in the disclosed embodiment, when it is detected that the touch operation is a multi-finger operation and the coaxial proximity condition is met, the self-capacitance signal value corresponding to the touch operation is used to compensate the mutual capacitance signal value, so that the envelope signal characteristics of the self-capacitance are used to fill the mutual capacitance signal, so that the reported coordinates are more stable, thereby improving the phenomenon of screen jitter caused by unstable coaxial operation point reporting under suspension conditions.

[0054] Embodiments of the Disclosure The touch signal control method involved in the embodiments of the disclosure is described below in combination with practical applications.

[0055] The embodiment of the present disclosure first describes that the touch operation satisfies the coaxial proximity condition.

[0056] In the embodiment of the present disclosure, when the detected touch operation meets the following conditions, it can be determined that the coaxial proximity condition is met:

[0057] (1) The distance between any two touch points in the horizontal direction is greater than or equal to a specified multiple of the distance between any two touch points in the vertical direction.

[0058] In the disclosed embodiment, assuming that the coordinates of the two touch points are (x1, y1) and (x2, y2), if |x1-x2|≥n |y1-y2|, it can be determined that the distance between the two touch points in the horizontal direction is greater than or equal to a specified multiple of the distance between the two touch points in the vertical direction, where n is a positive integer greater than or equal to 2.

[0059] It is understandable that in a typical game scenario, the mobile phone is in a horizontal screen state, so in the disclosed embodiment, it is determined that the distance between the horizontal axes is greater than or equal to a specified multiple of the distance between the vertical axes. If the mobile phone is in a vertical screen orientation, it is also possible to determine that the distance between the vertical axes is greater than or equal to a specified multiple of the distance between the horizontal axes.

[0060] (2) A multi-finger operation is detected, and at least two negative value blocks are detected in the diagonal direction of the touch screen, and the capacitance signal value of the touch point in the negative value block is negative.

[0061] In the embodiment of the present disclosure, if a two-finger operation or a multi-finger operation of more than two fingers is detected, the magnitude of the mutual capacitance signal detected in the diagonal direction of the touch screen is determined to determine whether there is a negative value block in the diagonal direction of the touch screen. Figure 2A There are two negative blocks in the diagonal direction.

[0062] (3) The change in the self-capacitance signal value detected in the set number of consecutive frames is less than or equal to the first set threshold.

[0063] In the embodiment of the present disclosure, the number of frames N1 is set, which can be an experimental value, for example, it can be set to 5, and it is an adjustable value. Furthermore, in the embodiment of the present disclosure, a threshold coefficient for determining that the self-capacitance value is relatively stable, such as TH1, can be set. Among them, TH1 can be an experimental value. Assuming that for 5 consecutive frames, △ diff_max1 ≤ TH1, it can be determined that the self-capacitance is relatively stable. Among them, △ diff_max1 can be understood as the change in the self-capacitance signal value. TH1 is the first set threshold.

[0064] (4) The change in the mutual capacitance signal value detected in the set number of consecutive frames is less than or equal to the second set threshold.

[0065] In the embodiment of the present disclosure, the number of frames N2 is set, which can be an experimental value, for example, it can be set to 5, and it is an adjustable value. Further, in the embodiment of the present disclosure, a threshold coefficient, such as TH2, can be set to determine whether the mutual capacitance value meets the suspension condition. Assuming that for 5 consecutive frames, diff_max2 ≤ TH2 * (Diff_max under good grounding), it can be determined that the mutual capacitance value meets the suspension condition. Among them, diff_max2 is the change in the mutual capacitance signal value, and TH2 is the second set threshold. Diff_max is the maximum mutual capacitance signal value when the grounding is good.

[0066] The disclosed embodiment can detect whether the touch signal corresponding to the touch operation detected in N consecutive frames meets the above-mentioned coaxial proximity condition. If the coaxial proximity condition is detected in N consecutive frames, it can be determined that the self-capacitance signal value needs to be compensated for the mutual capacitance signal value.

[0067] In the embodiments of the present disclosure, when the self-capacitance signal value corresponding to the touch operation is used to compensate the mutual capacitance signal value, the mutual capacitance compensation can be performed according to the envelope characteristics of the self-capacitance touch signal. Figure 4 The figure shows the envelope characteristic of the self-capacitive touch signal. Figure 4 As shown in FIG. 1 , the self-capacitive touch signal shows a peak value at the finger touch position. Therefore, in the embodiment of the present disclosure, the mutual capacitance signal value can be compensated according to the set ratio of the self-capacitive relative stable signal to compensate the mutual capacitance signal with two peak values ​​into one peak value, such as Figure 5 shown.

[0068] In the embodiment of the present disclosure, when using the self-capacitance signal value corresponding to the touch operation to compensate the mutual capacitance signal value, the compensation capacitance value can be determined based on the self-capacitance signal value corresponding to the touch operation and the proportionality coefficient, and the sum of the compensation capacitance value and the mutual capacitance signal value corresponding to the touch operation is used as the compensated mutual capacitance signal value.

[0069] Among them, the proportionality coefficient when performing mutual capacitance compensation in the embodiment of the present disclosure may be an experimental value set after multiple experiments. In one embodiment of the present disclosure, the proportionality coefficients corresponding to the multiple mutual capacitance signals generated by the touch operation are centrally symmetrical, and the proportionality coefficient at the center position is the largest, for example Figure 6 shown.

[0070] Furthermore, in the embodiments of the present disclosure, when mutual capacitance compensation is performed, the product of the self-capacitance signal value corresponding to the touch operation and the proportionality coefficient may be used as the compensation capacitance value.

[0071] In an example, Figure 7 As shown, the mutual capacitance Diff is the 7th in the X direction and the 12th in the Y direction. The node Diff value is 32, and the self-capacitance value of the 7th channel in the X direction is 300. Figure 8 According to the mutual capacitance compensation method involved in the embodiment of the present disclosure, the compensated mutual capacitance Diff is 92= 32 + 300*20%.

[0072] Furthermore, in the embodiment of the present disclosure, when it is detected that the touch operation meets the coaxial departure condition, the use of the self-capacitance signal value to compensate the mutual capacitance signal value may be cancelled.

[0073] Fig. 9 is a flow chart of a touch signal control method according to an exemplary embodiment. Fig. 9 As shown, the following steps are included.

[0074] In step S21, a touch operation is detected.

[0075] In step S22, it is detected whether the touch operation is a multi-finger operation and satisfies the coaxial proximity condition.

[0076] If the touch operation is a multi-finger operation and meets the coaxial proximity condition, step S23 can be performed. If the detected touch operation is not a multi-finger operation and does not meet the coaxial proximity condition, step S21 can be repeated.

[0077] In step S23, it is determined whether the operations corresponding to the touch operations detected in N consecutive frames are all multi-finger operations and meet the coaxial proximity condition.

[0078] If the operations corresponding to the touch operations detected in N consecutive frames are all multi-finger operations and meet the coaxial proximity condition, step S24 may be executed, otherwise the process returns to step S21.

[0079] In step S24, the mutual capacitance signal value is compensated by using the self capacitance signal value corresponding to the touch operation.

[0080] In step S25, it is detected whether the touch operation satisfies the coaxial departure condition.

[0081] When it is detected that the touch operation satisfies the coaxial leaving condition, step S26 may be executed. When it is detected that the touch operation does not satisfy the coaxial leaving condition, the process returns to step S22.

[0082] In step S26, the use of the self-capacitance signal value to compensate the mutual-capacitance signal value is canceled.

[0083] In the disclosed embodiment, when it is detected that the touch operation is a multi-finger operation and meets the coaxial proximity condition, the self-capacitance signal value corresponding to the touch operation is used to compensate the mutual capacitance signal value, so that the mutual capacitance signal is filled with the envelope signal characteristics of the self-capacitance, so that the reported coordinates are more stable, thereby improving the phenomenon of screen jitter caused by unstable coaxial operation point reporting under suspension conditions.

[0084] Based on the same concept, an embodiment of the present disclosure further provides a touch signal control device.

[0085] It is understandable that in order to realize the above functions, the touch signal control device provided by the embodiment of the present disclosure includes hardware structures and / or software modules corresponding to the execution of each function. In combination with the units and algorithm steps of each example disclosed in the embodiment of the present disclosure, the embodiment of the present disclosure can be implemented in the form of hardware or a combination of hardware and computer software. Whether a function is executed in the form of hardware or computer software driving hardware depends on the specific application and design constraints of the technical solution. Those skilled in the art may use different methods to implement the described functions for each specific application, but such implementation should not be considered to exceed the scope of the technical solution of the embodiment of the present disclosure.

[0086] Fig.10 FIG. 1 is a block diagram of a touch signal control device according to an exemplary embodiment. Fig.10 , the device includes a detection unit 101 and a compensation unit 102.

[0087] The detection unit 101 is used to detect a touch operation and detect that the touch operation is a multi-finger operation and satisfies the coaxial proximity condition. The compensation unit 102 is used to compensate the mutual capacitance signal value using the self-capacitance signal value corresponding to the touch operation when the detection unit 101 detects that the touch operation is a multi-finger operation and satisfies the coaxial proximity condition.

[0088] In one implementation, the detection unit 101 detects whether the touch operation meets the coaxial proximity condition in the following manner:

[0089] The distance between any two touch points in the horizontal direction of the multiple touch points is greater than or equal to a specified multiple of the distance between the two touch points in the vertical direction. Multi-finger operation is detected, and at least two negative value blocks are detected in the diagonal direction of the touch screen, and the capacitance signal value of the touch point in the negative value block is negative. The change in the self-capacitance signal value detected in the continuous set frame number is less than or equal to the first set threshold. And the change in the mutual capacitance signal value detected in the continuous set frame number is less than or equal to the second set threshold.

[0090] In another implementation manner, the second set threshold is determined according to a maximum mutual capacitance signal value and a specified coefficient when the grounding is good.

[0091] In another embodiment, the compensation unit 102 determines the compensation capacitance value according to the self-capacitance signal value corresponding to the touch operation and the proportionality coefficient, and uses the sum of the compensation capacitance value and the mutual capacitance signal value corresponding to the touch operation as the compensated mutual capacitance signal value.

[0092] In another embodiment, the compensation capacitance value is the product of the self-capacitance signal value corresponding to the touch operation and the proportionality coefficient.

[0093] In yet another embodiment, the proportionality coefficients corresponding to the multiple mutual capacitance signals generated by the touch operation are centrally symmetric, and the proportionality coefficient at the center is the largest.

[0094] In yet another implementation, the compensation unit 102 is further configured to:

[0095] When the detection unit 101 detects that the touch operation satisfies the coaxial leaving condition, the use of the self-capacitance signal value to compensate the mutual-capacitance signal value is canceled.
