Abstract

The invention provides a liquid crystal display panel. According to the liquid crystal display panel, each test terminal at the periphery of an array substrate is provided with a switch circuit, when static electricity on the test terminals needs to be released through the switch circuits, all the test terminals are connected with a common electrode wire, and the static electricity is released through the common electrode wire, such that the anti-ESD capability of the test terminals is enhanced, and the service life of the liquid crystal display panel is prolonged.

Description

【Technical field】 [0001] The invention relates to the technical field of liquid crystal displays, in particular to a liquid crystal display panel. 【Background technique】 [0002] At present, most of the small sizes adopt the GOA design (ColorfilterOnArray, the color filter layer is formed directly on the array substrate), and peripheral test pads (terminals) are designed on the left and right ends of the OLB (Outleadbonding, lead welding) terminal area. Peripheral test terminals mainly include test terminals that provide control signals to the Gate (gate), such as those that provide signals such as VGH (turn-on voltage of thin-film transistors) / VGL (turn-off voltage of thin-film transistors) / VDD (internal voltage of the device) / CKV Test terminals; test pads that provide Vcom (in-plane common voltage) to the panel; and test pads related to source driver chips. [0003] These test pads are mainly used for CellTest (liquid crystal display panel testing) and post-analysis testi...
