摘要:
The present invention provides a gate driving circuit applied for 2D-3D signal setting, comprising: a plurality of GOA units which are cascade connected, and a Nth GOA unit controls charge to a Nth horizontal scanning line G(n) in a display area, and the Nth GOA unit controls charge to a Nth horizontal scanning line G(n) in a display area, and the Nth GOA unit comprises a pull-up controlling part, a pull-up part, a transmission part, a first pull-down part, a bootstrap capacitor part, a pull-down holding part and a pull-up compensation part; on the basis of the gate driving circuit utilizing the present GOA skill, the present invention adds a pull-up compensation part to compensate the leakage gap existing in the 2D signal transmission to ensure that the voltage level of the gate signal point Q(N) will not descend in leakage gap period; by introducing an additional DC control signal source DC to control the activation and deactivation of the pull-up compensation part for activating it in 2D mode to realize co
