[0028] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are 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 making creative work are within the scope of protection of this application.

[0029] The disclosure below provides many different embodiments or examples to implement different structures of the present invention. In order to simplify the disclosure of the present invention, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention. In addition, the present invention can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0030] The present application embodiment proposes a method for controlling terminal reporting events. Figure 1 As shown, the method includes:

[0031] Step 101: when the terminal is in a charging state, obtaining at least two consecutive click events sent by the terminal and the reported point coordinates of each click event.

[0032] The positive and negative lines output by the charger are input into the positive voltage line and reference ground line of the whole machine. The interference signal output by the charger forms a differential signal on the positive and negative poles. The voltage difference between the two signals is basically the same even on the interference signal. Therefore, the interference signal on the differential signal has no interference to the TP (Touch Panel) sensor signal line or other loads. Figure 2 This is a schematic diagram of the interference signal of the capacitive screen when there is no finger touching it. At this time, the values ​​of capacitor cy3 and capacitor cy4 are very small.

[0033] When the charger is charging, when a person's hand touches the touch screen, the person's hand acts as the ground, and the signal on the capacitive screen and the reference ground signal are connected to the ground through capacitive coupling. The interference signal on the capacitive screen and the interference signal on the reference ground of the whole machine are different from the capacitance formed by the ground, resulting in different interference signals on the capacitive screen and the reference ground. A larger interference signal appears on the touch screen signal. Therefore, the above common-mode interference problem occurs: when the whole machine is charging and suspended, and the power supply voltage is unstable, there is a single-click double-point fault caused by common-mode interference. Figure 3 This is a schematic diagram of interference signals when a finger touches the capacitive screen. At this time, the values ​​of capacitor cy1 and capacitor cy2 are very large.

[0034] The reason for common mode interference is that when the finger clicks the screen and lifts the finger, the interference signal causes the capacitive touch screen to collect a pulse signal similar to that of a pen, and the capacitive touch screen switches to the capacitive pen writing mode. At this time, when the finger touches the screen and switches to the stylus writing mode, a finger touches the screen to report a point. Then, after the interference signal disappears, the screen switches back to the finger touch mode. At this time, the finger has not yet left the screen, and the screen collects the finger information. When the finger is lifted away from the screen, another point is reported, resulting in a failure of reporting two points during the single-click process. This phenomenon is easily perceived by users when using the input method to input letters.

[0035] Therefore, when the terminal is in a charging state, if common mode interference occurs, the terminal will send at least two consecutive click events to the central processor of the terminal, and each click event has corresponding reporting point coordinates.

[0036] Step 102: determining the click time interval between two consecutive click events according to the click events, and determining the click coordinate distance between two consecutive click events according to the reported point coordinates.

[0037] A click event includes a press sub-event and a lift sub-event. The central processing unit determines the press timestamp of the press sub-event in the current click event, and determines the lift timestamp of the lift sub-event in the previous continuous click event of the current click event; and takes the timestamp difference between the press timestamp and the lift timestamp as the click time interval.

[0038] At the same time, the central processing unit determines the pressed coordinates of the pressed sub-event in the current click event; determines the lifted coordinates of the lifted sub-event in the previous continuous click event of the current click event; and uses the coordinate distance between the lifted coordinates and the pressed coordinates as the click coordinate distance.

[0039] Step 103: When the click time interval is less than a preset time length and the click coordinate distance is less than a preset distance, determine that two consecutive click events are repeated point reporting events.

[0040] When a person's finger quickly clicks the capacitive screen at the same position, for example, a person clicks 20 times in 1 second. At this time, the event interval between two single-click events is 50 mm, so the time interval between two single-click events is usually greater than 30 milliseconds. However, due to interference, the double-click event is reported very quickly. According to actual multiple measurements, when interference causes a double-click event, the time interval between two single-click events is usually less than 25 milliseconds. The time interval threshold between two single-click events is set to 25 milliseconds. When the time interval between two consecutive click events is less than 25 milliseconds, it is considered that the single-click event caused by interference has formed a double-click or multiple click event.

[0041] However, when different fingers click at different positions, the time interval between click events performed by two different fingers may be less than 25 milliseconds. In order to eliminate the above situation, the central processing unit also needs to identify the position data of the coordinates of two or more click events.

[0042] When two consecutive reported points are at the same position, that is, the coordinate positions of two consecutive single-click events are the same, usually, because the interference disappears instantly, the coordinate positions of the two or consecutive click events caused by the interference are very close, and the coordinate point when the finger click caused by the interference becomes a double click will not exceed 5 mm, so the coordinate distance of the two click events is set to be less than 5 mm. When two fingers really click quickly at different positions, the positions of the two clicks will be larger than the finger area, so the coordinate distance formed by the two click events will be greater than 5 mm.

[0043] When the central processing unit recognizes that the distance between the coordinate points of two or more consecutive click events is less than 5 mm, preferably set to 1 mm, it can more accurately determine that the two reported points are repeated.

[0044] Step 104: Delete any of the repeated reporting events.

[0045] The central processing unit cancels any of the repeated reporting events and does not execute the response action of the single-click event, so that the current click only triggers one reporting event and forms a corresponding single-click event response. In this way, the user can perform a normal single-click operation even in the presence of interference.

[0046] In one implementation, the central processing unit may delete the second reporting event caused by the interference signal.

[0047] In an embodiment of the present application, the central processing unit obtains a single-click event, and then for consecutive single-click events, if the time interval between two consecutive single-click events is small and the coordinate distance is close, it is considered that the two consecutive single-click events are caused by the same click operation and reported double-click events, that is, capacitive pen input and handwriting input, and one of the repeated events is deleted, so that one click operation only generates one reporting event, ensuring normal user input.

[0048] Optionally, obtaining at least two consecutive click events sent by the terminal includes: obtaining at least two consecutive reporting events sent by the terminal and the reporting coordinates of each reporting event, wherein the reporting event includes a pressing sub-event and a lifting sub-event of the terminal capacitive screen; determining the reporting duration of the reporting event based on the pressing sub-event and the lifting sub-event in the same reporting event; and determining that the reporting event is a click event based on the reporting duration.

[0049] The capacitive touch screen uses the sensor to collect changes in capacitance signals to identify whether a finger touches the capacitive touch screen, and collects special pulse signals emitted by the stylus to identify whether the stylus touches the touch screen. When the stylus pulse signal is recognized, the capacitive touch screen collects the stylus pulse signal and reports the stylus coordinate signal to the terminal's central processing unit.

[0050] When a finger clicks the touch screen, the capacitive touch screen integrated chip obtains the information of the change of capacitance collected by the sensor on the capacitive touch screen, and calculates the coordinate position of the finger based on the information of the horizontal and vertical electrode sensors. At this time, the capacitive touch screen integrated chip sends a pressing sub-event to the central processing unit to inform the central processing unit that a finger starts to touch the capacitive touch screen. At the same time, the capacitive touch screen integrated chip sends coordinate information to the central processing unit at a certain time interval. When the finger is lifted from the capacitive touch screen, the capacitive touch screen integrated chip sends a lifting sub-event to the central processing unit, indicating that the finger leaves the touch screen sensor, and the process of the finger touching the capacitive screen ends, and stops sending coordinate information to the central processing unit. Figure 4 Schematic diagram of finger input.

[0051] The stylus input process is the same as the finger input process. After the capacitive touch screen receives the pulse signal from the stylus, the capacitive touch screen integrated circuit will send the pressing sub-event and lifting sub-event as well as the coordinate information to the central processing unit of the terminal. When the stylus touches the capacitive touch screen, the stylus sends a pulse signal outward, and the capacitive touch screen collects the signal sent by the stylus. After receiving the pulse signal sent by the stylus, the capacitive touch screen automatically switches to the stylus input mode under the corresponding protocol and exits the finger input operation mode.

[0052] Figure 5 This is a schematic diagram of finger input and stylus input. If the human hand touches the screen first, the screen will report the coordinate position information of the finger at the position of the hand; when the capacitive pen is close to the screen, the capacitive pen will send a pulse signal to the screen to pair with the capacitive touch screen. After the pairing is successful, it will switch to the stylus input mode. At this time, the position of the human hand is no longer reported, and the capacitive touch screen integrated circuit will report the coordinate position information of the stylus tip.

[0053] The central processing unit receives the pressing sub-event, continuous point coordinates and lifting sub-events sent by the capacitive touch screen integrated chip. According to the duration and position coordinates between the pressing sub-event and the lifting sub-event, it determines whether it is a click event, a long press or a stroke operation.

[0054] The central processing unit determines the pressing timestamp of the pressing sub-event and the lifting timestamp of the lifting sub-event in the point reporting event, and uses the timestamp difference between the lifting timestamp and the pressing timestamp as the reporting duration of the point reporting event. When the timestamp difference between the pressing sub-event and the lifting sub-event is less than the preset duration, it is determined to be a click event.

[0055] When the timestamp difference between the pressing sub-event and the lifting sub-event is greater than the preset duration, and the difference in the coordinates of the consecutive reported points is less than a certain value, it is judged as a long press event; when the timestamp difference between the pressing sub-event and the lifting sub-event is greater than the preset duration, and the difference in the coordinates of the consecutive reported points is greater than a certain value, it is judged as a line-drawing event.

[0056] The present application embodiment also provides a control flow diagram of a terminal reporting event, such as Figure 6 As shown, the following steps are included.

[0057] Step 601: The touch screen integrated circuit provides a pressing sub-event and a lifting sub-event to the central processing unit. After providing the pressing sub-event to the central processing unit, it provides coordinate data to the central processing unit at a certain time interval. The time interval is the time interval between two coordinate points reported under the fixed reporting rate of the touch screen. The lifting time marks the end of this touch event.

[0058] Step 602: The central processing unit determines whether it is a click event, a long press event, or a stroke event based on the time between the pressing sub-event and the lifting sub-event and the distance of the coordinate point change.

[0059] Step 603: If it is a click event, the central processing unit determines the time interval and coordinate distance between two click events.

[0060] Step 604: The central processing unit determines the distance between the coordinates after the pressing sub-event in the current single-click event and the coordinates before the lifting sub-event in the previous single-click event based on the time interval between the pressing sub-event in the current single-click event and the lifting sub-event in the previous single-click event. If the time interval is less than 25 mm, the central processing unit determines the distance between the coordinates after the pressing sub-event in the current single-click event and the coordinates before the lifting sub-event in the previous single-click event. When the distance is less than 5 mm, the judgment condition is met and it is determined that the current single-click event is a false alarm point caused by interference.

[0061] Step 605: The central processing unit removes the second point reporting and does not execute the response action of this single-click event.

[0062] The embodiment of the present application determines the time interval and position between two consecutive click events when performing a click operation on the capacitive screen, identifies whether the click is a normal user click or caused by interference, filters out the second point report caused by interference, ensures that the user performs normal click operation, and performs correct click input.
