Abstract

A Gate Driver on Array (GOA) circuit is disclosed. The GOA circuit comprising: a drive line scan control signal generation unit operative to generate a drive line scan clock signal and a drive line scan pulse signal; multiple GOA groups operative to acquire the drive line scan clock signal, to generate GOA group output signals sequentially according to GOA group input signals, wherein the GOA group output signal generated by one of the GOA groups is the GOA group input signal of a next GOA group to realize a shift register function of the multiple GOA groups; multiple drive line scan signal generation modules operative to acquire GOA group output signals and drive line scan pulse signal, and to generate drive line scan signals sequentially; multiple gate line groups operative to be applied with the drive line scan signals, to complete drive line scan for the multiple gate line groups sequentially.

Dependent claims

A Gate Driver on Array (GOA) circuit, comprising:

a drive line scan control signal generation unit operative to generate a drive line scan clock signal and a drive line scan pulse signal;
multiple GOA groups connected with the drive line scan control signal generation unit and connected in series with each other sequentially, which are operative to acquire the drive line scan clock signal, to generate GOA group output signals sequentially according to GOA group input signals, wherein the GOA group output signal generated by one of the GOA groups is the GOA group input signal of a next GOA group so as to realize a shift register function of the multiple GOA groups;
multiple drive line scan signal generation modules connected with the multiple GOA groups respectively and connected with the drive line scan control signal generation unit, which are operative to acquire the GOA group output signals and the drive line scan pulse signal, and to generate drive line scan signals sequentially;
multiple gate line groups connected with the multiple drive line scan signal generation modules respectively, which are operative to be applied with the drive line scan signals, so as to complete drive line scan for the multiple gate line groups sequentially.
