Problems solved by technology

[0004] In the prior art, when a liquid crystal display panel adopting HVA alignment technology and DBS technology is aligned, since no voltage is applied to the DBS electrode, 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. When the voltage is increased, the deflection angle of the liquid crystal corresponding to the pixel electrode near the DBS electrode area will be affected by the liquid crystal corresponding to the DBS electrode, which affects the transmittance of the liquid crystal display panel.

Abstract

The present invention provides a liquid crystal display panel and an alignment method thereof, the voltage equal to the pixel voltage is input into the DBS electrode under the 255 gray scale, the deflection of the liquid crystal at the DBS electrode can be consistent with the deflection of the liquid crystal at the pixel electrode in the alignment process, and therefore the brightness of the liquid crystal display panel at the DBS electrode under the 255 gray scale is improved, and the transmittance of the liquid crystal display panel is further improved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a liquid crystal display panel and an alignment method thereof. 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. 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 inject liquid crystal molecules between the thin film transistor array substrate (ThinFilm Transistor Array Substrate, TFTArray Substrate) and the color filter substrate (ColorFilter, CF), and apply a driving voltage to the two substrates to control The rotation direction of the liquid crystal molecules is used to refract the lig...
