Plane-field array substrate and display device

Abstract

An embodiment of the invention provides a plane-field array substrate and a display device and relates to the technical field of display. When the plane-field array substrate is applied to the display device containing a liquid crystal layer, the liquid crystal molecules in the liquid crystal layer at corresponding data line and / or grating line positions can be allowed to turn towards a direction vertical to a substrate body. The plane-field array substrate comprises a data line, a grating line, a pixel electrode, a public electrode and a first electrode and / or a second electrode, wherein the first electrode corresponds to the data line in position, and the second electrode corresponds to the grating line in positon; the first electrode and the data line and the second electrode and the grating line can form a vertical electric field on one side, without the substrate body, of the plane-field array substrate so as to drive the liquid crystal molecules to turn towards the direction vertical to the substrate body.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a flat field array substrate and a display device. Background technique [0002] Liquid Crystal Display (LCD for short) is favored by engineers because of its low power consumption, light and thin appearance, and no radiation. Therefore, it has been widely used in various electronic products including computers, mobile phones, etc. in electronic equipment. [0003] A liquid crystal display generally includes a VA (Vertical Alignment, vertical alignment) mode, a TN (Twist Nematic, twisted nematic) mode and a planar field mode. Among them, the planar field mode generally includes ADS (Advanced-SuperDimensional Switching, advanced super-dimensional field switch) type, IPS (In Plane Switch, transverse electric field effect) type, FFS (Fringe Field Switching, fringe field switch) and so on. The alignment of the liquid crystal molecules in the display device of the planar field mode...

AI Technical Summary

Problems solved by technology

The alignment of the liquid crystal molecules in the display device of the planar field mode is almost parallel to the plane where the display panel is located. Under the action of the electric field, the liquid crystal molecules will undergo unidirectional mobility, which in turn causes the phenomenon of unilateral accumulation of the liquid crystal molecules in the display panel. resulting in uneven display brightness

[0004] In the prior art, the phenomenon of unilateral accumulation of liquid crystal molecules is generally reduced by reducing the total amount of liquid crystal molecules, reducing the aging temperature, or reducing the deflection voltage of liquid crystal molecules, etc., but none of the above methods can essentially reduce the liquid crystal molecule One-way fluidity, but also will bring adverse effects on the display device

For example, by lowering the deflection voltage of the liquid crystal molecules and reducing the intensity of the electric field, the phenomenon of unilateral accumulation of liquid crystal molecules can be reduced, but this method will reduce the gray scale of the display screen, which in turn will affect the quality of the display screen.
