Embodiment 1

[0044] refer to figure 2 , this embodiment provides a touch recognition method, including:

[0045] Step S101, sequentially setting a first preset area and a second preset area on each edge of the touch area, and the width of the first preset area is the same as that of the second preset area;

[0046] Step S102, dividing the second preset area into N intervals;

[0047]Step S103, detecting the coordinate track of the touch operation on the touch area;

[0048] Step S104, judging whether any coordinate point in the coordinate track is located in the second preset area;

[0049] Step S105, if there is a coordinate point located in the second preset area, according to the interval where the coordinate point is located, the corresponding stretching coefficient is used to stretch to obtain the stretched coordinate point.

[0050] Specifically, step S101 is executed to sequentially set a first preset area and a second preset area on each edge of the touch area, wherein the firs...

Abstract

The present invention provides a touch recognition method, device, and touch display device. The method includes: sequentially setting a first preset area and a second preset area on each edge of the touch area, the width of the first preset area and the width of the second preset area. The two preset areas have the same width; divide the second preset area into N intervals; detect the coordinate track of the touch operation on the touch area; determine whether there is a coordinate point in the coordinate track located in the second preset area; if a coordinate point is located in the second preset area, then according to the interval where the coordinate point position is located, the corresponding stretch coefficient is used to stretch to obtain the stretch coordinate point; the area is set at the edge, and the area is The method of stretching the coordinates within can effectively identify the user's touch on the edge of the touch area, and the method is simple and the amount of calculation is small.

Description

technical field [0001] The present invention relates to the field of touch technology, in particular to a touch recognition method, device and touch display device. Background technique [0002] In a mutual capacitance multi-touch system, refer to figure 1 , when the finger touches the edge of the touch screen, part of the finger will be pressed outside the screen, resulting in incomplete data. Therefore, when the touch IC firmware uses the center of gravity algorithm to calculate the coordinates of the edge, it will cause the coordinates to shift to the center. , causing distortion. Contents of the invention [0003] The purpose of the present invention is to propose a touch recognition method, device and touch display device, which can effectively improve the problem of data incompleteness and distortion of coordinate points during calculation due to finger pressing outside the screen in the above-mentioned prior art . [0004] A touch recognition method, comprising: ...
