Abstract

The invention provides a GOA circuit, which includes a GOA driving chip, a GOA driving signal line, an array substrate test chip, a test signal line and a GOA protection circuit; the GOA driving chip is used to generate a scanning driving signal; the GOA driving signal line is used to transmit and scan The drive signal is sent to the corresponding scan line; the array substrate test chip is used to generate the array substrate test signal; the test signal line is used to transmit the array substrate test signal to the corresponding scan line; the GOA protection circuit is arranged on the GOA drive signal line and the test signal line Between them, it is used to prevent the static signal on the test signal line from being transmitted to the GOA drive signal line. The present invention also provides a liquid crystal display panel. The GOA circuit and the liquid crystal display panel of the present invention can effectively prevent static electricity from entering the GOA circuit through the test signal line, thereby preventing the GOA circuit from being damaged by static electricity.

Description

technical field [0001] The invention relates to the field of display screen driving, in particular to a GOA circuit and a liquid crystal display panel. Background technique [0002] With the development of technology, more and more users use various liquid crystal display panels for work, study and entertainment. Therefore, users have higher and higher requirements for liquid crystal display panels, such as high resolution, high brightness, and high response rate. [0003] The GOA (gate on array) circuit is an important circuit for driving a liquid crystal display panel in a liquid crystal display, and is used to realize the progressive driving of the scanning line (gate) to realize the normal display of the liquid crystal display panel. The array substrate test (array test) circuit is a circuit for testing the electrical connection of the GOA circuit. [0004] In the existing liquid crystal display panel design scheme, the signal lines of the GOA circuit, such as STV (sta...
