GOA (Gate Driver On Array) circuit, array substrate and liquid crystal display

Abstract

The invention discloses a GOA (Gate Driver On Array) circuit, an array substrate and a liquid crystal display. The circuit comprises a GOA module and a time division multiplexing module, wherein the GOA module comprises N GOA units, the output end of one GOA unit is connected with the input end of the next GOA unit, the reset end of one GOA unit is connected with the output end of the next GOA unit, and the output end of each GOA unit forms each output end of the GOA module; the time division multiplexing module comprises M control ends, N input ends and N*M output ends, the input ends of the time division multiplexing module are in corresponding connection with the output ends of the GOA module, the N*M output ends are in corresponding connection with N*M scanning lines of the array substrate, the M control ends are in one-to-one corresponding connection with M signal selection lines; and the time division multiplexing module is set to conduct connection between corresponding input ends and output ends according to selection signals received by the M control ends. The GOA circuit becomes a two-dimensional structure from a one-dimensional structure, the number of GOA units included in the GOA circuit can be reduced, and product reliability is improved.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a GOA circuit, an array substrate and a liquid crystal display. Background technique [0002] In recent years, Low Temperature Poly-Silicon (LTPS for short) technology has been widely used in high-end mobile phones and tablet products. Liquid crystal displays based on LPTS technology have many advantages such as low power consumption, high response rate, and high aperture ratio. Therefore, LPTS technology is one of the indispensable and important technologies for producing high-PPI products. [0003] With the continuous development of LTPS technology, narrow borders and low cost have gradually become an important development direction of liquid crystal displays. Comply with this development trend, GOA (GateDriveronArray) circuit has been widely used. The GOA circuit uses the same film-forming method as semiconductor devices such as in-plane liquid crystal drive s...

Problems solved by technology

[0005] However, since the GOA circuit is directly integrated on the array substrate by film formation, a certain area still needs to be reserved on both sides of the display area of ​​the liquid crystal display panel for the formation of the GOA circuit, which is obviously not conducive to narrow-frame liquid crystal display. realization of
