Abstract
A display device including a display circuit, a touch panel, a detection circuit, and a sensing circuit is disclosed. The display circuit generates a plurality of driving signals. The touch panel displays an image according to the driving signals. The detection circuit detects the display circuit. When the display circuit stops generating the driving signals, the detection circuit asserts a control signal. The sensing circuit detects the touch panel to obtain whether an area of the touch panel is touched when the control signal is asserted.
