Problems solved by technology
The response time of the touch screen is an important performance index of touch control. At the same time, the touch response time is also a part of the system response time. A touch panel with a slow response time will have a short pause and no movement can be detected, which is a serious problem. affect user experience
[0004] At present, in order to achieve a better user experience (active pen writing) for IWB products, the Sensor Pitch (sensor pixel pitch) cannot be designed larger, so that the number of Sensors (sensors) is large, and the current touch scanning methods of touch screens are all According to the order of the touch screen from top to bottom or from bottom to top, the full screen scans the change of touch capacitance line by line or column by line, and then locks the position of touch coordinates to realize touch control, which leads to long data processing time and slow response time , for IWB products, especially large-size IWB products, it seriously affects the user experience

The invention provides a touch scanning method, a chip, a storage medium and a display device. The touch control scanning method comprises the steps: when a touch control signal is obtained, scanningall touch control areas at a first scanning frequency, according to scanning original data, determining the touch control area where a touch control point is located to be a touch point area, and determining the touch control area, except the touch point area, in a touch control panel to be a contactless area; scanning the area with the contact at a first scanning frequency, and sending the scanned original data to a terminal control unit TMCU to execute a touch operation according to the scanned original data; and scanning the contactless area at a second scanning frequency, and sending the scanned original data to a micro-processing unit MCU corresponding to the contactless area, the first scanning frequency being greater than the second scanning frequency. According to the touch scanning method, the chip, the storage medium and the display device, the touch response time can be shortened, and the user experience is improved.
Description
technical field [0001] The present invention relates to the field of display technology, in particular to a touch scanning method and device, a chip, a storage medium, and a display device. Background technique [0002] The market size of IWB (LCD interactive whiteboard) shows a rapid growth trend, and is considered to be the mainstream technical media for the integration of information technology and subject courses in future classroom teaching. At present, infrared touch technology has many deficiencies in terms of touch sensitivity, writing accuracy, and appearance weight. Capacitive touch technology is gradually replacing infrared touch because of its better touch user experience. [0003] Capacitive touch screens can be divided into Add On Mode Touch Panel, On Cell Touch Panel and In-cell Touch Panel according to the structure. Among them, the embedded touch screen is to set the touch electrodes inside the display screen, which can reduce the overall thickness of the ...
