摘要：
A touch detection method is used in a touch panel. The touch panel is capacitive touch panel integrated with a display panel. The method includes at least obtaining at least one control signal carrying synchronous information from the display panel. The control signal is used to control the display panel to display an image. The method also includes analyzing the control signal to obtain an interference time period, at which the touch panel is possibly interfered, and generating a trigger signal. A driving voltage signal and a sensing period of the touch panel are controlled according to the trigger signal, so that the sensing period is not overlapped with the interference time period.
