[0002] As an important interactive interface in modern electronic devices, the performance of touch screens directly affects the user experience. The working principle of touch screens is based on a variety of technologies, such as resistive, capacitive, and infrared technologies.

[0041] In order to explain the technical content, structural features and achieved effects of the present application in detail, the following is a detailed description in combination with the implementation methods and the accompanying drawings.

[0042] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0043] Embodiment 1

[0044] See also Figures 1 to 7 , the present application discloses a touch device scanning method, comprising:

[0045] S1, dividing a touch area of ​​a touch device into a plurality of touch areas.

[0046] See also Figure 2 , when analyzed in combination with this specific example, the touch screen can be divided into four areas, namely touch area A, touch area B, touch area C and touch area D.

[0047] It should be noted that the touch screen is a possible implementation form of the touch area of ​​the touch device. The touch device may include multiple touch screens or touch panels, and each touch screen or touch panel can be divided into multiple areas. This example is only a specific embodiment of the touch area division of the touch device.

[0048] See also Figure 3 Specifically, each touch area corresponds to a number of sensing channels (RX) and a number of driving channels (TX), and the sensing channels and the driving channels jointly determine the coordinate information of the touch area.

[0049] The touch screen includes sensing channels RX1-RX8 and driving channels TX1-TX13.

[0050] The touch area A corresponds to the rectangular area surrounded by the sensing channels RX7-RX8 and the driving channels TX1-TX5, the touch area B corresponds to the area surrounded by the sensing channels RX5-RX6 and the driving channels TX1-TX8, and the area surrounded by the sensing channels RX7-RX8 and the driving channels TX6-TX8, the touch area C corresponds to the area surrounded by the sensing channels RX3-RX4 and the driving channels TX1-TX10, and the area surrounded by the sensing channels RX5-RX8 and the driving channels TX9-TX10, and the touch area D corresponds to the area surrounded by the sensing channels RX1-RX2 and the driving channels TX1-TX13, and the area surrounded by the sensing channels RX3-RX8 and the driving channels TX11-TX13.

[0051] Of course, this example is only one solution for dividing the touch area. The solution of this embodiment can also be divided into various other forms, such as being divided into multiple rectangles, and the number is not limited.

[0052] S2, detecting in real time whether a touch event occurs in each touch control area.

[0053] The sensing channel is the channel in the touch screen used to receive and sense touch signals, while the driving channel is the channel in the touch screen used to send driving signals. The driving channel activates the sensing channel on the touch screen by sending alternating current or voltage signals. In a capacitive touch screen, the sensing channel is equivalent to one pole of the capacitor, and the driving channel is equivalent to the other pole of the capacitor. The sensing channel and the driving channel together form a stable capacitor network. When a finger or other conductor approaches the touch screen, a new capacitor is formed between the sensing channel and the driving channel. The change in this capacitance is captured by the touch screen control chip and converted into a touch signal. By measuring the changes in these capacitances, the system can determine the specific location of the touch event.

[0054] S3, when it is detected that there are both a touch area where a touch event is occurring and a touch area where a touch event has not occurred (is not occurring), the touch area where the touch event is occurring is scanned at a first scanning frequency, and the touch area where the touch event has not occurred is scanned at a scanning frequency lower than the first scanning frequency.

[0055] Specifically, the first scanning frequency is a scanning frequency in a normal working mode.

[0056] In some embodiments, scanning a touch area where no touch event occurs at a scanning frequency lower than the first scanning frequency includes:

[0057] When there are multiple touch areas where no touch event occurs, the corresponding scanning frequencies are determined according to the distances from the touch areas where touch events are occurring.

[0058] Specifically, the scanning frequency of the touch control area where no touch event occurs decreases gradually as the distance from the touch control area where a touch event is occurring increases.

[0059] See also Figure 4 and Figure 5 , when analyzed in combination with a specific example, when the user's finger slides from touch area A to touch area D, corresponding touch events A, touch event B, touch event C and touch event D are triggered respectively.

[0060] During this touch process, when the finger is in touch area A, touch area A executes the first scanning frequency eHz, touch area B executes the scanning frequency b1Hz, touch area C executes the scanning frequency c1Hz, and touch area D executes the scanning frequency d1Hz, where e>b1>c1>d1, and eHz is the frequency of the normal working mode.

[0061] Specifically, b1 = 1 / 2*e, c1 = 1 / 4*e, d1 = 1 / 8*e, but the present invention is not limited thereto.

[0062] When the finger slides to touch area B, touch area B executes the first scanning frequency eHz, touch area A executes the scanning frequency a2Hz, touch area C executes the scanning frequency c2Hz, and touch area D executes the scanning frequency d2Hz, where e>a2=c2>d2, and eHz is the frequency of the normal operating mode.

[0063] Specifically, a2=c2=1 / 2*e, d2=1 / 4*e, but the present invention is not limited thereto.

[0064] When the finger slides to touch area C, touch area C executes the first scanning frequency eHz, touch area A executes the scanning frequency a3Hz, touch area B executes the scanning frequency b3Hz, and touch area D executes the scanning frequency d3Hz, where e>b3=d3>a3, and eHz is the frequency of the normal operating mode.

[0065] Specifically, b3=d3=1 / 2*e, a3=1 / 4*e, but the present invention is not limited thereto.

[0066] When the finger slides to touch area D, touch area D executes the first scanning frequency eHz, touch area A executes the scanning frequency a4Hz, touch area B executes the scanning frequency b4Hz, and touch area C executes the scanning frequency c4Hz, where e>c4>b4>a4, and eHz is the frequency of the normal operating mode.

[0067] Specifically, c4=1 / 2*e, b4=1 / 4*e, a4=1 / 8*e, but the present invention is not limited thereto.

[0068] See also Figure 6In some embodiments, scanning a touch area where no touch event occurs at a scanning frequency lower than the first scanning frequency includes:

[0069] S31, obtaining usage frequency information of each touch area.

[0070] Specifically, the touch device obtains touch signals through the sensing channel and the driving channel, and transmits these touch signals to the driver controller (Driver Controller). The driver controller converts these touch signals into digital signals, extracts information such as touch position and pressure, and then transmits them to the microcontroller (MCU) for processing. The microcontroller then stores this information in the data storage (Data SRAM).

[0071] The data storage system systematically stores and accumulates the user's interaction data on each touch area, including but not limited to key information such as the user's usage frequency and touch coordinates. Through the recorded interaction data, a big data system about usage frequency information is constructed.

[0072] The method of the embodiment of the present application is to configure the scanning frequency information of each touch area according to the user's usage habits to ensure timely response while saving energy consumption. Generally speaking, the higher the user's usage frequency of a touch area, the higher the possibility that the touch area will be used before the next touch operation begins. Therefore, the method of the present application needs to establish big data information based on the usage frequency information.

[0073] S32, updating scanning frequency configuration information when no touch event occurs in each touch control area based on the usage frequency information.

[0074] Specifically, the scanning frequency configuration information includes scanning frequency, clock frequency, number of scanning lines and scanning time, and the scanning frequency is lower than the first scanning frequency.

[0075] In the embodiment of the present application, by setting up an MCU-NPU module (neural network processor) to parse and logically summarize the data in the data storage, the computing power and computing efficiency can be greatly enhanced. Specifically, the touch device includes a number of registers, each register corresponds to a touch area, and the neural network processor logically summarizes and calculates the big data information to obtain the scanning frequency information of each touch area, and writes these scanning frequency configuration information into the corresponding register.

[0076] Specifically, the higher the historical usage frequency of the touch area, the higher the corresponding scanning frequency. Generally speaking, a touch area with a high usage frequency is regarded as a high-usage frequency touch area, and a touch area with a low usage frequency is regarded as a low-usage frequency touch area. Configuring the scanning frequency of the high-usage frequency touch area to a relatively high frequency and the low-usage frequency touch area to a relatively low frequency can improve the response speed of the high-usage frequency touch area and save power consumption in the low-usage frequency area.

[0077] S33, when it is detected that there are both a touch area where a touch event is occurring and a touch area where no touch event has occurred, scanning the touch area where no touch event has occurred with corresponding scanning frequency configuration information.

[0078] Specifically, the MCU accesses a register corresponding to the touch area, and calls the scanning frequency information in the register to scan the corresponding touch area.

[0079] See also Figure 7 The following is an exemplary description of the scanning process of the touch device in the embodiment of the present application, which should not be regarded as a limitation to the present application.

[0080] If the touch control device detects that touch event A occurs in touch area A, touch area A executes the first scanning frequency, and the remaining touch areas B, C and D are scanned according to the scanning frequency information configured in their registers B, C and D.

[0081] When the finger slides from touch area A to touch area B, the touch device detects that touch event B occurs in touch area B, then touch area B executes the first scanning frequency, and the remaining touch areas A, C and D are scanned according to the scanning frequency information configured in their registers A, C and D.

[0082] When the finger slides from touch area B to touch area C, the touch device detects that touch event C occurs in touch area C, then touch area C executes the first scanning frequency, and the remaining touch areas A, B and D are scanned according to the scanning frequency information configured in their registers A, B and D.

[0083] When the finger slides from touch area C to touch area D, the touch device detects that touch event D occurs in touch area D, then touch area D executes the first scanning frequency, and the remaining touch areas A, B and C are scanned according to the scanning frequency information configured in their registers A, B and C.

[0084] Specifically, the usage frequency information is updated after each group of touch events in the touch area occurs.

[0085] It is understandable that when the user's finger touches the touch screen to the finger leaves, multiple touch events will be triggered. This application regards these touch events as a group of touch events (it is understandable that the touch events here are different from the touch events of the aforementioned touch areas). When a touch operation occurs, the touchstart event, touchmove event, and touchend event will be triggered, corresponding to the touch operations of the finger starting to contact the touch screen, the finger sliding on the screen, and the finger leaving the screen. Touch events are the key to handling user touch interactions in web pages and applications. Each event carries touches, targetTouches, and changedTouches attributes for tracking touch status. The Touch object contains coordinate information, which makes it easy for developers to build operations that respond to touch. These events play an important role in interactive design on mobile devices.

[0086] Generally speaking, the neural network processor will recalculate and update after the touchend event, that is to say, in the process from the touchstart event to the touchend event, the scanning frequency of each area has not changed. When the finger leaves the screen, the data storage device will update the usage frequency information of each area, and the neural network processor will recalculate the usage frequency information to update the scanning frequency information in the register. Of course, it can also be set so that the neural network processor recalculates once every preset time period, and the preset time period can be set as needed. Generally speaking, the state when the user is in use is the active state, and the state when no touch event occurs is the idle state. The update of the scanning frequency occurs in the idle state. Since the user's usage habits will change over time, and the data storage device can update the big data information in time, the neural network processor can calculate in time and adjust the scanning frequency information in the register to ensure the smooth response of the touch screen when the user performs touch operations, which is conducive to improving the user experience.

[0087] In the embodiment of the present application, the touch device scanning method divides the touch device into multiple touch areas, detects in real time whether a touch event occurs, scans the touch area where the touch event is occurring at a first scanning frequency, and scans other touch areas where no touch event occurs at a scanning frequency lower than the first scanning frequency. The method of the embodiment of the present application scans by area, while ensuring touch sensitivity, reducing the power consumption of the overall touch screen in the working mode, which is beneficial to improving the endurance of the touch device and responds to the market demand for low-energy touch devices.
