[0002] As an important channel for human-computer interaction, the touch screen plays an important role in terminal equipment.

[0003] The basic working principle of the touch screen is capacitive sensing. When the user's finger or object touches the sensing material on the surface of the touch screen, it will cause the capacitance to change. The touch screen can calculate the coordinates of the object pressed on the touch screen surface through an algorithm and report the coordinates.

[0004] However, since some capacitive flexible screens have large display interference and the structure of the capacitive flexible screen itself leads to poor anti-interference, when the touch screen of the terminal device is interfered by noise, false alarm points often occur, thus affecting the user experience. Summary of the invention

[0031] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the specific technical solution of the present application will be further described in detail below in conjunction with the drawings in the embodiments of the present application. The following embodiments are used to illustrate the present application, but are not used to limit the scope of the present application.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein are only for the purpose of describing the embodiments of this application and are not intended to limit this application.

[0033] In the following description, reference is made to “some embodiments”, which describe a subset of all possible embodiments, but it will be understood that “some embodiments” may be the same subset or different subsets of all possible embodiments and may be combined with each other without conflict.

[0034] It should be pointed out that the terms "first\second\third" involved in the embodiments of the present application are used to distinguish similar or different objects, and do not represent a specific ordering of the objects. It can be understood that "first\second\third" can be interchanged in a specific order or sequence where permitted, so that the embodiments of the present application described here can be implemented in an order other than that illustrated or described here.

[0035] The basic working principle of the touch screen is capacitive sensing. When the user's finger or object touches the sensing material on the surface of the touch screen, it will cause the capacitance to change. The touch screen can calculate the number of fingers or objects currently pressing on the touch screen surface through an algorithm.

[0036] The touch screen can periodically trigger a scanning signal of a certain frequency to detect whether an object is pressed on the surface of the terminal touch screen, and calculate the coordinates based on the capacitive signal for reporting.

[0037] The following describes the principle of capacitive touch screen recognition of objects:

[0038] The capacitive sensing function of the touch screen uses the capacitive sensing principle of the touch screen to determine whether an object is in contact with the touch screen and then report the state of the object. The contacting objects are mainly fingers, stylus and other objects. The state of the object is mainly divided into the pressed state, the lifted state and the moving state after being pressed.

[0039] Based on the capacitive sensing principle of the touch screen, the touch screen recognizes the coordinates of an object by calculating the capacitance difference between the current object in contact with the touch screen and when it does not touch the touch screen. By calculating the area of ​​the capacitance difference, the peak difference value of the area is found to determine whether it is within a certain preset reporting threshold, and the reporting coordinates are sent from the terminal system.

[0040] The capacitive touch screen is mainly composed of a transmitting channel and a receiving channel, wherein the capacitance data collected from the transmitting channel and the receiving channel to the ground is self-capacitance data, and the data collected from the transmitting channel and the receiving channel is mutual capacitance data.

[0041] In the related art, mutual capacitance data is generally used to determine whether an object is in a pressed state, a moved state, or a lifted state relative to the touch screen. Self-capacitance data can also be used to determine other auxiliary functions, such as proximity sensing function, waterproof judgment, etc.

[0042] The following describes the classification of capacitive touch screen sensing types:

[0043] Capacitive touch screen sensing types can be divided into self-capacitance and mutual capacitance.

[0044] Among them, self-capacitance means that both the horizontal electrode and the vertical electrode are driven by a single-ended sensing method, that is, the driving circuits of a row and a column are the same, which is also called single-ended sensing.

[0045] Mutual capacitance refers to the situation where one axis is driven by a set of AC signals, and the response across the touch screen is sensed by electrodes on other axes. This is called transverse sensing because the electric field is transmitted from one electrode group (such as row) to another electrode group (such as column) through the dielectric layer of the upper panel in a transverse manner.

[0046] (1) Mutual capacitance:

[0047] The sending end and the receiving end are different and cross vertically.

[0048] ITO is used to make horizontal electrodes and vertical electrodes. The difference between it and a capacitor is that a capacitor will be formed where the two sets of electrodes intersect, that is, the two sets of electrodes constitute the two poles of the capacitor respectively.

[0049] When an object touches a capacitive touch screen, it affects the coupling between the two electrodes near the touch point, thereby changing the capacitance between the two electrodes. When detecting the mutual capacitance, the horizontal electrodes send out excitation signals in sequence, and all the vertical electrodes receive the signals at the same time. In this way, the capacitance value of all the intersection points of the horizontal and vertical electrodes can be obtained, that is, the capacitance value of the entire two-dimensional plane of the touch screen.

[0050] Figure 1 A schematic diagram of the working principle of mutual capacitance is given.

[0051] like Figure 1 As shown, in the double-layer stacked pattern, the spacing between the transmitting channel TX and the receiving channel RX is more than 150um, so that the suspension effect is better and the impact of dripping water is small.

[0052] In the single-layer bridging solution and the single-layer multi-point solution, the distance between the transmitting channel TX and the receiving channel RX is small, the suspension effect is poor, and the dripping effect is large.

[0053] Ultra-thin double-layer pattern, the distance between the transmitting channel TX and the receiving channel RX is about 50um, the suspension effect is poor, and the dripping effect is large.

[0054] In mutual capacitance, X+Y channels are needed to obtain X*Y data, which can support multi-point operation.

[0055] Mutual capacitance is better at preventing water and common-mode interference than self capacitance.

[0056] (2) Self-capacitance:

[0057] The transmitting end and receiving end of the self-capacitor are the same. ITO is used to make horizontal and vertical electrode arrays on the glass surface, and each of them forms a capacitor with the ground.

[0058] When an object touches the capacitive screen, the capacitance of the object will be added to the capacitance of the screen, increasing the capacitance of the screen.

[0059] Figure 2The working principle diagram of self-capacitance is given. Figure 2 As shown, the method of separate sampling in the X direction and the Y direction requires the number of channels X+Y, and can only support single-point plus gesture.

[0060] The form of the triangular pattern, such as Figure 3 As shown, the number of channels is Y*2 (or X*2) with single-layer wiring, which is low cost, and some solutions can support partitioning and multi-point.

[0061] Incell's solutions mostly use a checkered pattern, requiring X*Y number of channels to support multiple fingers.

[0062] Most of the self-capacitors (non-incell) in the related technology use the method of sending signals in all channels at the same time and sampling in a single channel in sequence. Since there is no ground wire in the center of the screen, it has better waterproof and anti-common mode interference (such as charger) effects.

[0063] An embodiment of the present application provides an information processing method, which is applied to a terminal device.

[0064] The terminal devices involved in the embodiments of the present application may include general handheld electronic terminals, such as mobile phones, smart phones, portable terminals, terminals, personal digital assistants (PDA), portable multimedia players (Personal Media Player, PMP) devices, laptop computers, notebooks (Note Pad), wireless broadband (Wireless Broadband, Wibro) terminals, tablet computers (personal computers, PCs), smart PCs, sales terminals (Point of Sales, POS) and vehicle-mounted computers, etc.

[0065] Terminal devices may also include wearable devices. Wearable devices are portable electronic devices that can be worn directly on the user or integrated into the user's clothes or accessories. Wearable devices are not just hardware devices, but can also achieve powerful intelligent functions through software support, data interaction, and cloud interaction, such as: computing function, positioning function, and alarm function. They can also be connected to mobile phones and various terminals. Wearable devices may include but are not limited to watches supported by the wrist (such as watches, wrists, etc.), shoes supported by the feet (such as shoes, socks, or other products worn on the legs), Glass supported by the head (such as glasses, helmets, headbands, etc.), and various non-mainstream product forms such as smart clothing, school bags, crutches, accessories, etc.

[0066] Figure 4 The following is a schematic diagram of the implementation process of the information processing method provided in the embodiment of the present application. Figure 4As shown, the method may include the following steps 401 to 403:

[0067] Step 401: determine the current state of the touch screen of the terminal device, where the current state includes a noise interference state and a non-noise interference state.

[0068] It is understandable that some capacitive flexible screens have greater display interference, and the structure of the capacitive flexible screen itself leads to poor anti-interference. When the touch screen of the terminal device is interfered by noise, false alarm points often occur, thus affecting the user experience.

[0069] Based on this, in an embodiment of the present application, it is possible to first determine whether the current state of the touch screen of the terminal device is a noise interference state or a non-noise interference state, thereby selecting different processing methods based on the different current states of the touch screen.

[0070] In the embodiment of the present application, the current state of the touch screen of the terminal device can be determined in a variety of ways.

[0071] For example, in some embodiments, the current state of the touch screen may be determined by executing steps 501 to 502 in the following embodiments:

[0072] Step 501, detecting the current charging status signal of the terminal device.

[0073] It is understandable that if the terminal device is in a charging state, the noise interference caused by the charger will cause the capacitance data detected by the touch screen system to cause coordinate jitter, resulting in an increased probability that the same technique, clicking the screen, will turn into a sliding operation.

[0074] In the embodiment of the present application, there is no limitation on the implementation method of detecting the current charging status signal of the terminal device.

[0075] For example, in some embodiments, if the terminal device can monitor the interruption event of inserting the charger through the port and can obtain the voltage and current of the charger, it can be determined that the current charging status signal of the terminal device detected is used to characterize that the terminal device is in a charging state.

[0076] If the terminal device detects an interruption event of unplugging the charger through the port, it can be determined that the detected current charging state signal of the terminal device is used to indicate that the terminal device is not in a charging state.

[0077] The port may be a USB port or a Type C port, which is not limited in the embodiment of the present application.

[0078] Step 502, determining the current state of the touch screen according to the charging state signal, wherein, when the charging state signal indicates that the terminal device is in a charging state, determining that the current state of the touch screen is a noise interference state; or, when the charging state signal indicates that the terminal device is not in a charging state, determining that the current state of the touch screen is a non-noise interference state.

[0079] Here, if it is determined according to the charging status signal that the terminal device is in a charging state, it can be determined that the current state of the touch screen is a noise interference state; if it is determined according to the charging status signal that the terminal device is not in a charging state, it can be determined that the current state of the touch screen is a non-noise interference state.

[0080] In some other embodiments, the current state of the touch screen may be determined by executing steps 601 to 602 in the following embodiments:

[0081] Step 601: Detect noise data of the touch screen.

[0082] It is understandable that the touch screen may scan noise data when scanning signals.

[0083] The hardware module uses an independent channel for scanning, that is, this channel is not connected to the ITO sensing material, and the capacitance data is not affected when an object is pressed. When there is external noise interference, the touch screen can collect the noise independently. In the existing channel, the TX channel does not print the code, does not send the signal, and scans the RX channel alone as the scanned noise data.

[0084] Step 602: when the noise data of the touch screen is greater than or equal to the noise threshold, determine that the current state of the touch screen is a noise interference state; or when the noise data of the touch screen is less than the noise threshold, determine that the current state of the touch screen is a non-noise interference state.

[0085] If the detected noise data of the touch screen is greater than or equal to the noise threshold, it can be determined that the current state of the touch screen is a noise interference state; if the detected noise data of the touch screen is less than the noise threshold, it can be determined that the current state of the touch screen is a non-noise interference state.

[0086] There is no limitation on the setting of the noise threshold, which can be set according to actual conditions.

[0087] Step 402, according to the correspondence between the preset state and the lock point threshold and the current state, determine the target lock point threshold corresponding to the current state, and the lock point threshold is determined according to the distance threshold and / or the reporting frame number interval threshold.

[0088] In the embodiment of the present application, after the current state of the touch screen of the terminal device is determined, the target lock point threshold corresponding to the current state can be found from the correspondence between the preset state and the lock point threshold.

[0089] Among them, in some embodiments, if the current state is a noise interference state, the target lock point threshold is the first lock point threshold; if the current state is a non-noise interference state, the target lock point threshold is the second lock point threshold, and the second lock point threshold is less than the first lock point threshold.

[0090] In an embodiment of the present application, the lock point threshold may be determined based on a distance threshold, or may be determined based on a reporting frame number interval threshold; or, may be determined based on both a distance threshold and a reporting frame number interval threshold.

[0091] Step 403: Process the received touch coordinates according to the target lock point threshold, and report the processed touch coordinates.

[0092] In the embodiments of the present application, based on different methods for determining the lock point threshold, after determining the target lock point threshold, the methods for processing the received touch coordinates and reporting the processed touch coordinates are also different.

[0093] For example, if the lock point threshold is determined according to the distance threshold, step 403 may be implemented by executing steps 703 to 706 in the following embodiment.

[0094] If the lock point threshold is determined according to the reporting frame number interval threshold, step 403 may be implemented by executing steps 803 to 805 in the following embodiment.

[0095] If the lock point threshold is determined based on the distance threshold and the reporting frame number interval threshold, step 403 may be implemented by executing steps 903 to 907 in the following embodiment.

[0096] In the embodiment of the present application, when the touch screen is in different noise states, different target lock point thresholds are set when processing the received touch coordinates. In this way, even when the touch screen is interfered by noise, different target lock point thresholds are set to process the received touch coordinates before reporting, thereby reducing the probability of false alarm points and improving the accuracy of reporting touch coordinates.

[0097] Figure 7 The following is a schematic diagram of the implementation process of the information processing method provided in the embodiment of the present application. Figure 7 As shown, the method may include the following steps 701 to 706:

[0098] Step 701: determine the current state of the touch screen of the terminal device, where the current state includes a noise interference state and a non-noise interference state.

[0099] Step 702, according to the correspondence between the preset state and the lock point threshold and the current state, determine the target lock point threshold corresponding to the current state, and the lock point threshold is determined according to the distance threshold.

[0100] Step 703 , in response to the touch signal received in the current frame, obtain the touch coordinates of the current frame.

[0101] Here, there is no limitation on the execution entity that initiates the touch signal. For example, the user may press or slide the touch screen with his finger so that the touch screen receives the touch signal; or the user may press or slide the touch screen with a stylus so that the touch screen receives the touch signal.

[0102] It can be understood that for touch operations such as pressing or sliding, the touch screen can parse out the touch coordinates corresponding to each frame of touch signals in multiple frames of touch signals during execution, and the parsing process is real-time.

[0103] That is, the touch screen can respond to the touch signal received in the current frame and parse the touch coordinates corresponding to the touch signal of the current frame, that is, the current pressing or sliding coordinates of the user's finger or stylus relative to the touch screen.

[0104] Step 704 , determining whether the first distance between the touch coordinates of the current frame and the touch coordinates of the initial frame is less than the target lock point threshold; if yes, executing step 705 ; otherwise, executing step 706 .

[0105] In the embodiment of the present application, the initial frame may be a previous frame of the current frame, or the current frame may be one of multiple frames corresponding to the touch operation, and the initial frame may be the first frame of the touch operation.

[0106] In the embodiment of the present application, in order to avoid coordinate reporting errors caused by jitter caused by noise interference, when the initial frame is the previous frame of the current frame, after the touch coordinates of the current frame are obtained, the first distance between the touch coordinates of the current frame and the touch coordinates of the previous frame adjacent to it can be calculated, and the first distance can be compared with the target lock point threshold. If the first distance is less than the target lock point threshold, it can be considered that the moving distance between the current frame and the previous frame is small, indicating that the touch operation has a high probability of being a press operation, and the touch coordinates of the two frames can be determined to be the same, so the touch coordinates of the initial frame (i.e., the previous frame) can be reported to the terminal device.

[0107] If the first distance is less than the target lock point threshold, it can be considered that the moving distance between the current frame and the previous frame is large, and the execution subject (such as a finger) that initiates the touch signal has a high probability of performing a sliding operation. Therefore, it can be considered that the touch coordinates of the two adjacent frames are not the same, and the touch coordinates of the current frame are reported to the terminal device.

[0108] Similarly, to avoid coordinate reporting errors caused by jitter caused by noise interference, when the initial frame is the first frame of the touch operation, after obtaining the touch coordinates of the current frame, the first distance between the touch coordinates of the current frame and the touch coordinates of the previous frame adjacent to it can be calculated, and the first distance can be compared with the target lock point threshold. If the first distance is less than the target lock point threshold, it can be considered that the moving distance between the current frame and the first frame of the touch operation is small, indicating that the touch operation is more likely to be a press operation, and the touch coordinates of the current frame and the first frame of the touch operation can be determined to be the same, so the touch coordinates of the initial frame (i.e., the first frame) can be reported to the terminal device.

[0109] If the first distance is less than the target lock point threshold, it can be considered that the moving distance between the current frame and the first frame is large, and the execution subject (such as a finger) that initiates the touch signal has a high probability of performing a sliding operation. Therefore, it can be considered that the touch coordinates of the current frame and the first frame of the touch operation are not the same, and the touch coordinates of the current frame are reported to the terminal device.

[0110] Step 705: reporting the touch coordinates of the initial frame.

[0111] Step 706: Report the touch coordinates of the current frame.

[0112] In an embodiment of the present application, it is first determined whether the current state of the touch screen of the terminal device is a noise interference state or a non-noise interference state, and based on the correspondence between the preset state and the lock point threshold and the current state, the target lock point threshold corresponding to the current state is determined, and the lock point threshold is determined based on the distance threshold; after receiving the touch signal of the current frame, the touch screen can respond to the touch signal to obtain the touch coordinates of the current frame; then, it can be determined whether the first distance between the touch coordinates of the current frame and the touch coordinates of the initial frame is less than the target lock point threshold; if so, the touch coordinates of the initial frame are reported; otherwise, the touch coordinates of the current frame are reported.

[0113] In this way, the lock point threshold is determined in advance through the distance threshold, and after the touch signal is received and the touch coordinates are parsed, the touch operation is judged as a press operation or a slide operation based on the relationship between the coordinate distance between two adjacent frames or the current frame and the first frame of the touch operation and the lock point threshold, thereby avoiding the press operation being misidentified as a slide operation when there is noise interference on the touch screen, resulting in a poor user experience.

[0114] Figure 8 The following is a schematic diagram of the implementation process of the information processing method provided in the embodiment of the present application. Figure 8 As shown, the method may include the following steps 801 to 805:

[0115] Step 801: determine the current state of the touch screen of the terminal device, where the current state includes a noise interference state and a non-noise interference state.

[0116] Step 802, according to the correspondence between the preset state and the lock point threshold and the current state, determine the target lock point threshold corresponding to the current state, and the lock point threshold is determined according to the reporting frame number interval threshold.

[0117] Step 803 , in response to the touch signal received in the current frame, obtaining the touch coordinates of the current frame.

[0118] Here, there is no limitation on the execution entity that initiates the touch signal. For example, the user may press or slide the touch screen with his finger so that the touch screen receives the touch signal; or the user may press or slide the touch screen with a stylus so that the touch screen receives the touch signal.

[0119] After the touch signal of the current frame is acquired in real time, the touch signal can be parsed to obtain the touch coordinates of the current frame. It should be noted that after the touch coordinates of the current frame are acquired, the touch coordinates can be reported or not reported.

[0120] Step 804, determining whether the frame number interval between the current frame and the last reported frame is the target lock point threshold.

[0121] Here, the last reported frame refers to a capture frame whose corresponding touch coordinates are reported to the terminal device before the current frame.

[0122] Step 805 : reporting the touch coordinates of the current frame when the frame number interval between the current frame and the last reported frame is the target lock point threshold.

[0123] Here, the touch coordinates of each frame are not reported to the terminal device after being obtained, but are selectively reported when the target lock point threshold is met, that is, when the reporting frame number interval threshold is met.

[0124] For example, if the reporting frame interval threshold is 3 frames and the last reported frame is the 1st frame, then if the current frame is the 4th frame and the frame interval between it and the last reported 1st frame is 3 frames, the touch coordinates of the current frame can be reported to the terminal device; if the current frame is the 3rd frame and the frame interval between it and the last reported 1st frame is 2 frames, then it is chosen not to report the touch coordinates of the current frame to the terminal device.

[0125] In an embodiment of the present application, it is first determined whether the current state of the touch screen of the terminal device is a noise interference state or a non-noise interference state, and based on the correspondence between the preset state and the lock point threshold and the current state, the target lock point threshold corresponding to the current state is determined, and the lock point threshold is determined based on the reported frame number interval threshold; after receiving the touch signal of the current frame, the touch screen can respond to the touch signal to obtain the touch coordinates of the current frame; then, it can be determined whether the touch coordinates of the current frame are at a frame number interval with the last reported frame for the reporting frame number interval threshold; if so, the touch coordinates of the current frame are reported; otherwise, the touch coordinates of the current frame are not reported.

[0126] In this way, the lock point threshold is determined in advance by the reporting frame number interval threshold, and after the touch signal is received and the touch coordinates are parsed, it is determined whether the current frame has met the reporting frame number interval. When the frame number interval between the current frame and the last reported frame has met the reporting frame number threshold, the touch coordinates of the current frame are reported, thereby avoiding the situation where the pressing operation is mistakenly identified as a sliding operation when there is noise interference on the touch screen, resulting in a poor user experience.

[0127] Fig. 9 The following is a schematic diagram of the implementation process of the information processing method provided in the embodiment of the present application. Fig. 9 As shown, the method may include the following steps 901 to 907:

[0128] Step 901: determine the current state of the touch screen of the terminal device, where the current state includes a noise interference state and a non-noise interference state.

[0129] Step 902, according to the correspondence between the preset state and the lock point threshold and the current state, determine the target lock point threshold corresponding to the current state, and the lock point threshold is determined according to the distance threshold and the reporting frame number interval threshold.

[0130] Here, the lock point threshold is determined based on the distance threshold and the reporting frame number interval threshold. That is, when determining whether the current frame can be reported, it must meet the judgment conditions of the above two thresholds at the same time.

[0131] Step 903 , in response to the touch signal received in the current frame, obtain the touch coordinates of the current frame.

[0132] Here, there is no limitation on the execution entity that initiates the touch signal. For example, the user may press or slide the touch screen with his finger so that the touch screen receives the touch signal; or the user may press or slide the touch screen with a stylus so that the touch screen receives the touch signal.

[0133] After the touch signal of the current frame is acquired in real time, the touch signal can be parsed to obtain the touch coordinates of the current frame. It should be noted that after the touch coordinates of the current frame are acquired, the touch coordinates can be reported or not reported.

[0134] Step 904: determine whether the frame number interval between the current frame and the last reported frame is a reporting frame number interval threshold.

[0135] Here, the last reported frame refers to a capture frame whose corresponding touch coordinates are reported to the terminal device before the current frame.

[0136] Step 905, when the frame number interval between the current frame and the last reported frame is the reporting frame number interval threshold, determine whether the second distance between the touch coordinates of the current frame and the touch coordinates of the initial frame is less than the distance threshold; if so, execute step 906; otherwise, execute step 907.

[0137] When the frame number interval between the current frame and the last reported frame is the reporting frame number interval threshold, it can be further determined whether the second distance between the touch coordinates of the current frame and the touch coordinates of the initial frame is less than the distance threshold.

[0138] The initial frame may be a previous frame of the current frame, or the current frame may be one of multiple frames corresponding to the touch operation, and the initial frame may be the first frame of the touch operation.

[0139] For example, if the reporting frame number interval threshold is 3 frames and the last reported frame is the 1st frame, then if the current frame is the 4th frame, and the frame number interval between it and the last reported 1st frame is 3 frames, it means that the frame number interval between the current frame and the last reported frame is the reporting frame number interval threshold; then, it is necessary to continue to judge the second distance between the current frame and the initial frame (such as the adjacent previous frame or the first frame of the touch operation). If the second distance is less than the distance threshold, it means that the touch operation is more likely to be a pressing operation, and it can be determined that the touch coordinates of the two frames are the same, so the touch coordinates of the initial frame (that is, the previous frame or the first frame of the touch operation) can be reported to the terminal device.

[0140] If the second distance is less than the distance threshold, it can be considered that the moving distance between the current frame and the initial frame (such as the adjacent previous frame or the first frame of the touch operation) is large, and the execution subject (such as a finger) that initiates the touch signal has a high probability of performing a sliding operation. Therefore, it can be considered that the touch coordinates of the current frame and the initial frame (such as the adjacent previous frame or the first frame of the touch operation) are not the same, and the touch coordinates of the current frame are reported to the terminal device.

[0141] Step 906: reporting the touch coordinates of the initial frame.

[0142] Step 907: reporting the touch coordinates of the current frame.

[0143] In an embodiment of the present application, it is first determined whether the current state of the touch screen of the terminal device is a noise interference state or a non-noise interference state, and based on the correspondence between the preset state and the lock point threshold and the current state, the target lock point threshold corresponding to the current state is determined, and the lock point threshold is jointly determined based on the distance threshold and the reporting frame number interval threshold; after receiving the touch signal of the current frame, the touch screen can respond to the touch signal to obtain the touch coordinates of the current frame; then, it can be determined whether the touch coordinates of the current frame and the last reported frame number interval are the reporting frame number interval threshold; if so, it is further determined whether the second distance between the touch coordinates of the current frame and the touch coordinates of the initial frame is less than the distance threshold; if so, the touch coordinates of the initial frame can be reported; otherwise, the touch coordinates of the current frame are reported.

[0144] In this way, the reporting frequency of detected touch coordinates can be reduced, thereby avoiding the situation where there is noise interference on the touch screen. Due to the displacement of touch coordinates between consecutive frames, when each touch coordinate is reported, the probability of misidentifying a press operation as a sliding operation will increase, resulting in a poor user experience.

[0145] The following describes an exemplary application of the embodiments of the present application in a practical application scenario.

[0146] Fig.10 This is the overall process of the information processing method provided in the embodiment of the present application. Fig.10 As shown, the method includes the following steps 1001 to 1004:

[0147] Step 1001: The system in the terminal device monitors the status of the charging cable by interruption.

[0148] Step 1002, based on the state of the currently detected charging cable, determine whether the charger state of the system in the terminal device is the plugged in state; if the charger is in the plugged in state, execute step 1003; if the charger is in the unplugged state, execute step 1004.

[0149] In step 1003, the system in the terminal device sets the second mode instruction function to the touch screen driver. After receiving the corresponding instruction, the touch screen driver sets to send the first instruction to the touch screen hardware system. After receiving the first instruction, the touch screen hardware system sets the register of the touch screen system through the interface, and switches the touch screen to the first lock point threshold according to the first instruction.

[0150] In step 1004, the system in the terminal device sets the first mode instruction function to the touch screen driver. After receiving the corresponding instruction, the touch screen driver is set to send the first instruction to the touch screen hardware system. After receiving the first instruction, the touch screen hardware system sets the register of the touch screen system through the interface, and switches the touch screen to the first lock point threshold according to the first instruction.

[0151] Among them, the Android system is divided into different software levels; the battery management system service is responsible for monitoring the insertion and removal status of the charger and determining whether the function needs to be turned on; the touch screen driver is responsible for receiving instructions from the upper system service and communicating data with the hardware device touch device, that is, the touch screen system.

[0152] The terminal system sets the touch screen system, currently mainly through the I2C interface, SPI interface or I3C interface. Set the registers in the touch screen system, which are the memory of the touch screen system.

[0153] The touch system is equipped with a CPU and a memory, and can also perform data calculations.

[0154] The first lock point threshold and the second lock point threshold can be distance parameters or time frame numbers.

[0155] In some embodiments, when a finger touches the touch screen, the touch screen will start a frame counter, and the counter will record the number of frames the finger presses to touch the screen. When the number of pressed frames is less than a preset number of frames, the point stabilization distance is increased; when it exceeds the preset number of frames, the point stabilization distance is reduced.

[0156] When the finger is pressed, the touch screen will record the initial coordinates (x, y); determine whether the distance between the current coordinates (x1, y1) and the initial coordinates (x, y) is less than the preset distance. If so, report the initial coordinates (x, y); otherwise, report the new coordinates (x1, y1).

[0157] In the embodiment of the present application, the terminal system monitors the two different states of the system charger being plugged in and unplugged, and by judging the system state of the charging line, if it meets the plugged in state, the touch screen system is set to switch to the second lock point threshold, and if it meets the unplugged state, the touch screen system is set to switch to the first lock point threshold. This improves the anti-interference performance, reduces the probability of the touch screen clicking changing and sliding, and improves the user experience.

[0158] In some embodiments, the touch screen system can also detect the current noise data to determine whether it reaches a preset threshold condition. If it reaches the threshold condition, it enters the noise mode and sets the touch screen system to switch to the second lock point threshold. If it does not reach the noise mode, it sets the touch screen system to switch to the first lock point threshold. In this way, the anti-interference performance can be improved, the probability of the touch screen clicking changing and sliding can be reduced, and the user experience can be improved.
