Abstract: A sensing device includes a sensing circuit, a conductive line, and a sampling circuit. The conductive line is electrically connected to the sensing circuit. The sampling circuit is electrically connected to the conductive line. The sampling circuit includes a capacitor, a first thin film transistor, and a second thin film transistor. The first terminal of the first thin film transistor is electrically connected to the first terminal of the capacitor. The first terminal of the second thin film transistor is electrically connected to the second terminal of the capacitor. The second terminal of the first thin film transistor is electrically connected to the conductive line. The second terminal of the second thin film transistor is electrically connected to the ground terminal.
