Abstract

The embodiment of the present invention discloses a liquid crystal display panel, comprising: a GOA circuit; a first opening signal line and a second opening signal line, the first opening signal line includes a first branch line and a second branch line; a control board, It is provided with a first connection point, a second connection point, a third connection point and a switching line, the second opening signal line is electrically connected to the first connection point, and the second branch line is electrically connected to the second connection point , the first connection point is used to input the start signal, the third connection point is used as a detection output point, the first end of the switching line is connected to the second connection point, and the second end of the switching line is connected to to the first connection point, and the second end of the switch line is switchably connected to the third connection point. The embodiment of the invention also discloses a liquid crystal display. Adopting the present invention has the advantages of low cost and simple circuit for detecting whether the GOA circuit is abnormal through the first opening signal line.

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...
