Abstract

The invention discloses a GOA driving circuit, and belongs to the Electronic technical field. The GOA driving circuit comprises a plurality of stages of GOA driving units. the nth GOA driving unit comprises a pull-up control module, a pull-down control module, a global control module, an auxiliary module, a reset module and an output module ; the pull-up control module is electrically connected with the pull-down control module and the global control module, the auxiliary module is electrically connected with the global control module and the reset module, and the output module is electricallyconnected with the global control module and the reset module; The pull-up control module is used for pulling up the global control module; The pull-down control module is used for pulling down the global control module; The output module is used for outputting a low-level signal to the output end of the nth GOA driving unit; The auxiliary unit is used for reducing capacitive coupling of the output module; And the reset module is used for pulling down the output signal of the output module. According to the GOA driving unit, the driving capability of each stage of GOA driving unit can be improved, and the requirements of low cost, narrow frame and thinness of a product are met.

Description

technical field [0001] The invention relates to the field of electronic circuits, in particular to a GOA drive circuit. Background technique [0002] The driving circuit in the liquid crystal display is mainly completed by connecting an integrated circuit (Integrated Circuit IC) outside the liquid crystal panel. In contrast, the Gate Driver On Array (Gate Driver On Array) technology, referred to as GOA technology, is a technology that directly manufactures the gate driver circuit on the array substrate to replace the external silicon chip to make the driver chip. Since GOA can be directly fabricated around the panel, the manufacturing process is simplified, and the cost can be reduced to improve the integration of the liquid crystal panel, so that the panel tends to be thinner. However, the currently used GOA drive circuit has an unstable output signal due to poor drive capability, which will cause pixel leakage and affect the display effect. Contents of the invention ...
