Gate driving circuit and gate driving method, gate driver on array (GOA) and display device
Abstract:
The present disclosure provides a gate driving circuit which can be applied in a display panel. The gate driving circuit may include a driving signal output unit, provided with a storage capacitor; a driving control unit, configured to sample an input signal in a first period of each scanning cycle, control the driving signal output unit to output a first gate driving signal which is configured to turn on thin film transistors (TFTs) in a display panel in a second period of each scanning cycle, and control the driving signal output unit to output a second gate driving signal which is configured to turn off the TFTs in the display panel by using the storage capacitor across which a voltage difference is within a predetermined range in a third period of each scanning cycle; and a compensating unit, configured to maintain the voltage difference across the storage capacitor to be within the predetermined range in the third period of each scanning cycle.
