Abstract
The present invention discloses a touch panel having a multitude of driving and sensing electrodes and a touch detecting method therefor. The method includes: driving each driving electrode, and detecting a change in coupling capacitance between each driving electrode and each sensing electrode to determine at least one sensing electrode corresponding to a touch position; multiplexing each one of the at least one sensing electrode corresponding to the touch position to be a generated driving electrode, and multiplexing each driving electrode to be a generated sensing electrode; driving the generated driving electrode, and detecting a change in coupling capacitance between the generated driving electrode and each generated sensing electrode to determine at least one driving electrode corresponding to the touch position; driving each driving electrode corresponding to the touch position, and detecting a change in coupling capacitance between each driving electrode and each sensing electrode corresponding to the touch position to determine the touch position.
