METHOD AND APPARATUS FOR DETECTING TOUCH ON CAPACITIVE TOUCH SCREEN |
摘要 |
<p>A method and an apparatus for detecting a touch on a capacitive touch screen are provided. The method includes: detecting a self-capacitance and a mutual capacitance of the capacitive touch screen in real-time, in which the self-capacitance and the mutual capacitance are detected in a time-sharing mode; determining whether a current self-capacitance changes with respect to a previous self-capacitance and whether a current mutual capacitance changes with respect to a previous mutual capacitance; determining that the capacitive touch screen is touched by a finger when the current self-capacitance changes with respect to the previous self-capacitance and the current mutual capacitance changes with respect to the previous mutual capacitance; determining that the capacitive touch screen is not touched by the finger when the current self-capacitance does not change with respect to the previous self-capacitance.</p> |
