Abstract
The present disclosure relates to the technical field of display, which provides a compensation device for a gate driving circuit and a method thereof, a gate driving circuit and a display device. The compensation device for a gate driving circuit, which the gate driving circuit includes a first shift register and a second shift register. The second shift register is configured to output a second scanning signal according to a first scanning signal output from the first shift register. Wherein, the compensation device for a gate driving circuit includes: a signal receiving unit, which is configured to receive the first scanning signal output from the first shift register; a signal compensation unit, which is configured to compare the first scanning signal with a reference voltage, and a compensation signal is output to the second shift register according to the comparison result to compensate the received first scanning signal.
