Abstract

The invention provides a GOA circuit and a display panel. The GOA circuit comprises a plurality of stages of GOA units which are arranged in a cascaded mode. Each GOA unit comprises a pull-up controlmodule, a pull-up module, a pull-down module, a pull-down maintenance module and a bootstrap capacitor; through sharing of part of circuits, each GOA unit can realize multistage scanning signal output, the structure of the GOA circuit is simplified, and then the narrow frame design of the display panel is realized.

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. In the existing GOA circuit, each GOA unit correspondingly outputs a scanning signal to a corresponding gate line in the display panel. The GOA circuit structure occupies a large wiring space, which is not conducive to realizing a narrow frame. Contents of the invention [0003] The present application provides a GOA circuit and a display panel to solve the technical problem in the prior art t...
