Abstract: A display panel including a pixel array, a plurality of first shift registers, a plurality of second shift registers, a plurality of first discharge circuits, and a plurality of second discharge circuits is provided. The pixel array includes a plurality of gate lines. The shift registers provide a plurality of gate signals to the gate lines. Each of the first discharge circuits receives a third gate signal to discharge a same first gate line together with the corresponding first shift register. A rising edge of the third gate signal substantially matches a falling edge of the corresponding first gate signal. Each of the second discharge circuits receives a fourth gate signal to discharge a same second gate line together with the corresponding second shift register. A rising edge of the fourth gate signal substantially matches a falling edge of the corresponding second gate signal.
