GATE DRIVING CIRCUIT AND DISPLAY APPARATUS HAVING THE SAME
摘要:
In a gate driving circuit and a display apparatus, the gate driving circuit comprises a plurality of stages. At least one of the stages comprises a pull-up section responsive to a first node signal; a pull-down section responsive to a second input signal; a discharging section discharging the first node signal in response to the second input signal; a first holding section responsive to the first clock signal, maintaining the first node signal at the off-voltage; and a second holding section responsive to the second clock signal, maintaining the first node signal at the off-voltage. The second holding section has a greater transistor width-to-length ratio than the first holding section. Therefore, an abnormal gate-on signal is less likely to occur, reducing driving defects of the display apparatus.
