Abstract
A touch panel and an operating method for the touch panel are provided. The touch panel includes touch areas and a sensing circuit. In a power saving mode, adjacent touch areas among the touch areas receive touch drive signals with different frequencies. At least two non-adjacent touch areas have the same frequency and different phases. The touch panel sends touch drive signals to the touch areas simultaneously within a time interval. The sensing circuit receives touch sensing signals from the touch areas in the power saving mode, and determines whether the touch panel is touched according to at least one of the touch sensing signals. The touch panel is controlled to enter a normal mode in response to the touch panel being touched.
