Abstract
Disclosed is a touch position detection method for a touch control device, which employs a preset scan detection mode to carry out driving and scan detection on first and second conductive layers through a control circuit. When touch on a touch panel is detected, the type of the touch is determined, which may include a single-point touch, a continuous trace, and a multiple-point touch, and first and second operation modes are selectively used to perform driving and scan detection on the first and second conductive layers of the touch panel to thereby detect coordinates of the touch points or the continuous trace.
