Abstract:
A driving circuit includes a driving transistor, a capacitor, a reset circuit, a touch sensing electrode, a sensing circuit, and a read circuit. The capacitor is electrically coupled to a gate terminal of the driving transistor. The reset circuit is electrically coupled to the gate terminal of the driving transistor, and the reset circuit is configured to reset the voltage level of the gate terminal of the driving transistor. The sensing circuit is electrically coupled between the touch sensing electrode and the gate terminal of the driving transistor, and the sensing circuit is configured to transmit the voltage level of the touch sensing electrode to the gate terminal of the driving transistor. The read circuit is electrically coupled to the driving transistor, and the read circuit is configured to output a touch sensing signal according to the voltage level of the gate terminal of the driving transistor.
