Abstract

The invention provides a display panel and a driving method thereof. The display panel comprises a grid driving circuit, and the gate driving circuit comprises a GOA module and a signal adjusting module. The signal adjusting module comprises M clock signal input terminals and M level signal input terminals, wherein the M is an integer greater than or equal to 2; and the clock signal input terminals and the level signal input terminals are in one-to-one correspondence. And the signal adjusting module is used for outputting a Kth level signal when a GOA signal is input and a Kth clock signal isinput into the Kth clock signal input terminal, wherein the K is an integer greater than or equal to 1 and less than or equal to M. The GOA signal output by the GOA module is adjusted through the signal adjusting module and the scanning pulse signals with the potentials decreased progressively in a stepped mode are finally output, so that the problem that the GOA signals directly fall from the high potential to the low potential, and voltage sudden change occurs is solved; then the breakdown phenomenon is avoided, the splash screen phenomenon of the display panel is avoided, and the display effect of the display panel is improved.

Description

technical field [0001] The present application relates to the display field, in particular to a display panel and a driving method thereof. Background technique [0002] When the display panel displays an image, it is necessary to use a gate drive circuit to scan the pixel units. The gate drive circuit includes a plurality of cascaded gate drive units. Each gate drive unit corresponds to a row of pixel units and can The gates of the thin film transistors in the units output scan pulse signals, thereby realizing the progressive scan driving of the pixel units of the display device. [0003] The gate drive circuit usually controls the potential level of the output signal at the output terminal through a plurality of transistors and capacitors. However, there is a parasitic capacitance between the gate and the drain of the thin film transistor in the display device, so when the level of the scan pulse signal applied by the gate drive circuit to the gate of the thin film transi...
