Abstract: A touch panel includes multiple sensing units and each thereof includes a first transistor, a reference capacitor, a liquid crystal capacitor and a second transistor. ON/OFF states of the first transistor are determined by a potential provided by a corresponding scan line. The reference capacitor and the liquid crystal capacitor are coupled in series between another scan line adjacent to the corresponding scan line and a common potential. A capacitance value of the liquid crystal capacitor changes with a pressed degree of the sensing unit. ON/OFF states the second transistor are determined by a potential at a connection node between the reference capacitor and the liquid crystal capacitor. The first transistor transmits a first potential to the connection node when the first transistor is turned on, and the second transistor transmits a second potential different from the first potential to a readout line when the second transistor is turned on.
