Abstract

The invention discloses a gate driver on array (GOA) drive substrate, which comprises a plurality of GOA circuit units, wherein each stage of GOA circuit unit comprises an output module, a resetting module, a holding module and an input module; the output modules are used for outputting scanning signals according to trigger signals of trigger nodes; the resetting modules are used for resetting the trigger signals according to resetting signals; the holding modules are used for holding the levels of the trigger signals and for pulling down the levels of the trigger signals; and the input modules are electrically connected to the holding modules and are used for receiving the scanning signals outputted from the previous stages of the GOA circuit units. Each of the input modules comprises a first CMOS transmission gate and a first transistor. According to the gate driver on array drive substrate disclosed by the invention, by virtue of the input module of each stage of GOA circuit unit, the equivalent conduction resistance of each of the transistors can be reduced and the drive current of each of the trigger nodes is improved so as to accelerate a level transmission rate, reduce the driving consumption of the transistors and improve the stability of the circuits.

Description

technical field [0001] The present invention relates to a liquid crystal display, especially a liquid crystal display using a gate drive (Gated driver on array, GOA) substrate. Background technique [0002] The GOA circuit utilizes the thin film transistor liquid crystal display Array process to fabricate the gate driver on the gate drive substrate with a thin film transistor (Thinfilm transistor, TFT) array, so as to realize the driving mode of progressive scanning. [0003] The GOA circuit includes several GOA circuit units, and the output module of each GOA circuit unit is driven by the trigger signal of the trigger node to output the scanning signal. However, if the driving current applied to the trigger node is not large enough, the quality of the scan signal output by the output module will be affected. Therefore, increasing the driving current of the trigger node of each GOA circuit unit in the prior art is the goal of the manufacturer. Contents of the invention ...
