Orientation method of liquid crystal display panels

Abstract

The invention provides an orientation method of liquid crystal display panels. The DBS electrode of each liquid crystal display panel in a liquid crystal display motherboard is connected with the common electrode of an array substrate; when voltage is provided for multiple liquid crystal display panels in the orientation process of the liquid crystal display motherboard, array substrate common voltage is provided for the DBS electrodes and the common electrode of the array substrate at the same time, wherein the array substrate common voltage is larger than or equal to the ground terminal voltage provided for data lines and finally input to pixel electrodes through opened TFTs, and is smaller than the color filter substrate common voltage provided for the common electrode of a color filtersubstrate. Compared with the prior art, liquid crystals corresponding to the DBS electrodes can be deflected in the orientation process, the influence of the liquid crystals on the liquid crystal deflection angle corresponding to the pixel electrodes is reduced, and the penetration rate of the liquid crystal display panels can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to an alignment method of a liquid crystal display panel. Background technique [0002] A liquid crystal display (Liquid Crystal Display, LCD) has many advantages such as thin body, power saving, and no radiation, etc., has been widely used, and occupies a dominant position in the field of flat panel display. [0003] Most of the liquid crystal displays currently on the market are backlight liquid crystal displays, which include a liquid crystal display panel and a backlight module. The working principle of the liquid crystal display panel is to pour liquid crystal molecules between the thin film transistor array substrate (ThinFilm Transistor Array Substrate, TFT Array Substrate) and the color filter substrate (ColorFilter, CF), and apply a driving voltage on the two substrates to Control the rotation direction of the liquid crystal molecules to refract the light fr...

Problems solved by technology

[0006] None of the existing power supply machines used in HVA alignment has terminals for supplying voltage to DBS electrodes, so that when liquid crystal display panels using HVA alignment technology and DBS technology are aligned, no voltage is applied to DBS electrodes, which is different from The liquid crystal corresponding to the DBS electrode does not rotate, and a voltage is applied between the pixel electrode and the CF common electrode. The deflection angle of the liquid crystal near the DBS electrode area in the liquid crystal corresponding to the pixel electrode will be affected by the liquid crystal corresponding to the DBS electrode.
