Gate driving circuit, display device and driving method thereof

Abstract

The embodiment of the invention, which relates to the field of display technology, relates to a gate driving circuit, a display device and a driving method thereof so that the existing GOA circuit based on the existing technology can not realize the waveform for driving the external compensation pixel circuit architecture can be solved. The gate driving circuit comprises M-stage shift registers. Each stage of shift register consists of a first register unit and a second register unit; the first register units of the M-stage shift registers are in cascade connection; the second register units of the M-stage shift register are in cascade connection; and the output terminal of the first register unit and the output terminal of the second register unit of each stage of shift register are connected electrically with the output terminal of the shift register at the level, wherein the M is a positive integer greater than or equal to 1. Compared with the prior art, with configuration and inputting of first clock signals with different waveforms and second clock signal with different waveforms, the gate driving circuit can output the required mixed-waveform gate driving signal, thereby providing the waveform for driving the external compensation pixel circuit architecture.
