Abstract:
A GOA circuit comprising GOA units and a liquid crystal display are disclosed. The N-staged GOA units charge the Nth-staged horizontal scanning line in the display region, and comprise N-staged pull-up control circuits, N-staged pull-up circuits, N-staged transfer circuits, N-staged pull-down circuits, and N-staged pull-down holding circuits. The N-staged pull-up circuits turn on when the Nth-staged gate signal point is at a high voltage level, receive a first clock signal and charge the N-staged horizontal scanning lines when the first clock signal is at a high voltage level. The N-staged transfer circuits receive a second clock signal when the Nth-staged gate signal point is at the high voltage level and output N-staged transfer signals to control the operation of the (N+1)-staged GOA units. The disclosure may ensure the scanning lines in the GOA circuit to be better charged for facilitating normal operation for each point in the circuit.
