Embodiment Construction

[0020] Such as figure 1 As shown, taking a display screen as an example to illustrate the scanning process and effect of the present invention, the touch screen is divided into N*M cells (N and M are positive integers), and the specific scanning steps are as follows:

[0021] (1) Obtain the content currently displayed on the screen by the touch screen driver, read all event cells corresponding to the display content and the touch probability of each cell, and download them to the touch screen control integrated circuit;

[0022] (2) The touch screen control integrated circuit dynamically counts the touch probability of each cell, adds it to the downloaded event cell probability to obtain the latest event cell probability, and then performs full-frame scanning on the touch screen to scan all N*M cells;

[0023] (3) Divide all event cells into K subsets according to the touch probability, the touch probability is the same as a subset, and the Ith subset contains L i The probabi...

Abstract

The invention relates to the technical field of touch screen scanning, in particular to a touch screen scanning method based on display content, a scanning device and a touch screen. The present invention counts the frequently touched event cells and their touch probabilities of each display screen in advance, calls its event cells and touch probabilities according to the screen display content at each scan, and establishes Only for the scan sequence of the event cell, the event cell responding to the touch is scanned multiple times, and the full frame scan and partial scan for the event cell are performed periodically. This method effectively reduces the total scanning volume, saves scanning power, and greatly increases the number of event cell scans, significantly improving the touch experience.

Description

technical field [0001] The invention relates to the technical field of touch screen scanning, in particular to a touch screen scanning method based on screen display content, a scanning device and a touch screen. Background technique [0002] The application of touch screens is becoming more and more popular, and a large number of touch screens are used in mobile phones, tablet computers (PADs), laptop computers, desktop computer displays, and vehicle display screens. In the touch screen application, the recognition of the position of the touch point and the number of touch points is to firstly divide the screen into several cells, and then scan each cell in a certain order or method to identify whether the position of each cell is is touched, and finally the process of counting the total number of touched cells is completed. Scanning all cells once is called scanning a frame. In the existing touch screen control integrated circuit, every time a frame is scanned, all cells...
