Abstract

The embodiment of the invention discloses a liquid crystal display panel. The liquid crystal display panel comprises: a GOA circuit comprising multi-level interconnected GOA units; a low-potential transmission wire electrically connected with the GOA units to transmit a low-potential voltage to the corresponding GOA units, wherein the low-potential transmission wire is provided with a voltage detection point; a low-potential supplying unit configured to supply and output a low-potential standard voltage; a compensation unit, wherein a first input end of the compensation unit is electrically connected with the low-potential supplying unit, a second input end of the compensation unit is electrically connected with the voltage detection point to detect voltage fluctuation on the low-potentialtransmission wire, an output end of the compensation unit is electrically connected with the low-potential transmission wire, and the compensation unit controls a voltage output to the low-potentialtransmission wire according to the voltage at the voltage detection point. The embodiment of the invention further discloses a liquid crystal display. The liquid crystal display panel and the liquid crystal display can avoid abnormal display of the liquid crystal display panel caused by capacitive coupling effect of the low-potential transmission wire.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a liquid crystal display panel and a liquid crystal display. Background technique [0002] Liquid crystal display panels have become display panels for mobile communication devices, PCs, TVs, etc. due to their high display quality, low price, and easy portability. At present, the driving technology of liquid crystal display panels tends to adopt GOA circuits. GOA circuits can simplify the manufacturing process of flat panel display panels and eliminate the bonding process in the direction of horizontal scanning lines, which can increase production capacity and reduce product costs. At the same time, it can improve display panels. The high level of integration makes it more suitable for making display products with narrow bezel or bezel-less, satisfying the visual pursuit of modern people. [0003] GOA circuit, that is, Gate Driver on Array technology, is to use the existing liq...
