US 2017/0255333 A1 · TOUCH POSITIONING METHOD FOR TOUCH PANEL

Abstract

An object positioning method for touch panel is disclosed. In the method, an amount of sensing of a sensing signal can be detected and a sensing coordinate of an object can be obtained based on the detection. A positioning coordinate of the object can be locked in a point-locked mode when the amount of sensing of the sensing signal decreases continuously to be larger than a first threshold time and the amount of sensing of the sensing signal is smaller than a first sensing threshold value. Otherwise, the point-locked mode of the positioning coordinate of the object can be unlocked when the amount of sensing of the sensing signal is larger than a first sensing threshold value.
