Abstract

The present application discloses a gate drive circuit and a display panel. The gate drive circuit includes a plurality of cascaded gate drive units. The gate drive unit of the Nth stage adopts the same clock through the pull-down control module, the maintenance module and the pull-down module. The combined signal can quickly pull down the falling edge of the N-level scanning signal to the potential of the constant-voltage low-potential signal, effectively shortening the falling time of the N-level scanning signal from high potential to low potential.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a gate drive circuit and a display panel. Background technique [0002] As a display component of an electronic device, a display panel has been widely used in various electronic products, wherein a gate driving circuit is an important component of the display panel. The gate drive circuit can also be called GOA (Gate Driver On Array, array substrate row drive) circuit, which uses the array (Array) process of the thin film transistor display to manufacture the gate (Gate) row scanning drive signal circuit on the Array substrate to realize A technology for the gate progressive scan driving method. [0003] However, the gate driving circuit is easily affected by various reasons, so that it takes a long time for the falling edge of the output scan signal to drop to a preset low potential, which easily worsens the working instability of the display panel. [0004] It sho...
