Abstract
The present invention provides a gate driving circuit, of which respective odd stage GOA unit circuits are cascade connected, and respective even stage GOA unit circuits are cascade connected; the odd stage first, second scan control signals (Vf, Vr), the odd stage scan start signal (STV), the odd stage first, second high frequency clock signals (CK1, CK2) are located corresponding to the odd stage GOA unit circuits; the even stage first, second scan control signals (Vf, Vr), the even stage scan start signal (STV), the even stage first, second high frequency clock signals (CK1, CK2) are located corresponding to the even stage GOA unit circuits; by controlling the voltage levels of the odd stage first, second scan control signals (Vf, Vr) and even stage first, second scan control signals (Vf, Vr) in cooperation with the odd stage scan start signal (STV) and the even stage scan start signal (STV) of different sequences, the odd stage GOA unit circuits and the even stage GOA unit circuits can be controlled to perform forward scan or backward scan at the same time or in time division.
