TOUCH SCREEN CONTROL METHOD AND DEVICE

摘要

A touch screen control method and device thereof are provided. The method includes: acquiring (102) the actual capacitance values of test points on the touch screen; identifying (104) the interference level of the electrically conductive medium according to change of the actual capacitance values relative to reference capacitance values; and controlling (106) the touch screen under the operation mode corresponding to the interference level. The present invention solves the problem that the sensitivity and detection precision of the capacitive touch screen are seriously impacted when the capacitive touch screen surface is covered with electrically conductive mediums, to a large extent mitigating the effect of electrically conductive mediums on the touch screen, and improving the sensitivity and detection precision of the touch screen by controlling the touch screen under the operation mode corresponding to the interference level according to the interference level of the electrically conductive mediums.
