Abstract

The invention provides a GOA circuit and a display panel. The GOA circuit comprises GOA units which are arranged in a multi-stage cascade mode. Each GOA unit comprises a bootstrap module; the bootstrap effect of the bootstrap module is utilized, so the grid voltage of the output transistor is improved, the rising time and the falling time of scanning signals output by each GOA unit can be effectively shortened, and therefore the charging capacity of the display panel is improved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a GOA circuit and a display panel. Background technique [0002] Array substrate gate drive technology (Gate Driver Array, referred to as GOA), is to integrate the gate drive circuit on the array substrate of the display panel to realize the driving method of progressive scanning, so that the gate drive circuit part can be saved, and it has the advantages of The advantages of reducing production cost and realizing narrow bezel design of the panel are used for various displays. However, for high-resolution and high-frequency display panels, due to the short charging time, the capacitive load of the scanning line is heavy, the distortion of the scanning signal is serious, and the risk of wrong charging is high, resulting in insufficient charging capacity, which in turn causes abnormal display of the display panel. . Contents of the invention [0003] The present appl...
