The invention belongs to the technical field of touch screens and provides a self-capacitive touch screen edge touch coordinate compensation method. The present invention is directed to a touch-sensitive display device for touching a touch screen boundary, the coordinates of two directions perpendicular to each other are constructed into a functional relation, and the coordinates perpendicular tothe boundary direction and the coordinates parallel to the boundary direction are taken as input quantities, the coordinates parallel to the boundary direction are taken as the amount to be compensated, when the position of the touch is closer to the edge, the coordinates perpendicular to the boundary direction and the coordinates parallel to the boundary direction are used as inputs for functioncalculation to obtain the coordinates compensation amount parallel to the boundary direction, and the compensation amount is added with the existing coordinates parallel to the boundary direction, soas to obtain the coordinates closer to the real touch position. The invention is simple and reliable, is convenient to debug, the compensated coordinates are smooth and have no sudden change, the touch error of the touch screen edge can be basically eliminated, the touch precision is improved, and the user experience is improved.
Description
technical field [0001] The invention relates to the technical field of touch screens, in particular to a method for compensating edge touch coordinates of a self-capacitance touch screen. Background technique [0002] Because the capacitive touch screen has high sensitivity, good transmittance and supports multi-touch, capacitive touch technology is more and more widely used in the field of human-computer interaction consumer electronics products, including mobile phones, tablets, notebook computers, etc., and the market demand is strong. [0003] At present, capacitive touch technology can be roughly divided into two identification methods: self-capacitance and mutual capacitance. In some cost-sensitive applications, self-capacitance touch screens are widely used. Currently, self-capacitance touch screens generally use triangular electrode wiring. The touch coordinate distortion at the edge of the touch screen with this structure is relatively large, mainly due to the disto...
