Abstract
A method for determining a change of an initial distance of a sensing electrode is provided. The method includes: calculating a real-time pressure output by each sensing electrode according to real-time feature data output by each sensing electrode in a touch screen when a pressure is applied on the touch screen and a corresponding relationship between the feature data and the pressure; rectifying the real-time pressure output by each sensing electrode according to prestored relative elastic coefficients at different press positions relative to each sensing electrode; and determining a sensing electrode whose initial distance is changed among all the sensing electrodes according to a difference between the rectified real-time pressures output by different sensing electrodes, to calibrate the corresponding relationship between the feature data and the pressures of the sensing electrode whose initial distance is changed.
