Problems solved by technology

[0002] Array substrate gate drive technology (GateDriveronArray, GOA) is to directly manufacture gate drive circuits (GatedriverICs) on the array (Array) substrate, which can be directly made around the panel, reducing the production process and reducing product costs. With the narrow frame design It is becoming more and more popular, and the surrounding space of the panel design is gradually compressed. In the traditional GOA circuit design, the height of the wiring space of each level of GOA circuit is consistent with the corresponding pixel size. Now the products with 4K or higher ppi resolution are gradually Popularity, the size of the pixel is getting smaller and smaller, and the height of the space left for the GOA circuit for wiring is also reduced. Due to the height limit, a larger width can only be used to make up for the wiring. The design of the narrow frame very unfavorable

Abstract

The invention relates to a liquid crystal drive display device which comprises a display region and a liquid crystal drive circuit. The liquid crystal drive circuit comprises a plurality of stages of GOA circuits. Each stage of GOA circuit comprises gate lines and an auxiliary pull-down circuit, wherein the gate lines comprise an odd group of grid lines and an even group of grid lines, and the auxiliary pull-down circuit comprises a first group of auxiliary pull-down circuit and a second group of auxiliary pull-down circuit. The odd group of grid lines and the even group of grid lines are arranged at the two sides of the display region separately and respectively; the first group of auxiliary pull-down circuit and the second group of auxiliary pull-down circuit are also arranged at the two sides of the display region separately and respectively; and any two stages of GOA circuits in the plurality of stages of GOA circuits share the first group of auxiliary pull-down circuit and the second group of auxiliary pull-down circuit.
