Problems solved by technology

[0004] However, the inventors found that the alignment direction of the existing PI material after Rubbing alignment, that is, the pretilt angle of the branched chain of the PI material, has been fixed. When the electric field drives the liquid crystal to deflect, the liquid crystal molecules need to overcome the molecular action of the branched chain of the PI molecule. The deflection is caused by force, and the response time at this time is relatively large, generally around 25-45ms

Embodiment 1

[0025] Such as figure 1 As shown, the present embodiment provides a display substrate, and the display substrate may be an array substrate, a color filter substrate, or a cell-to-cell substrate of course. The array substrate in this embodiment includes an alignment layer 20 disposed on the substrate 10, and the material of the alignment layer 20 is composed of a polymer with a branch; wherein, the dielectric of the long axis and the short axis of the branch The constants are different.

[0026] What needs to be explained here is that, figure 1 It is shown that the material of the alignment layer 20 has branched chains in the microscopic case, but actually in the macroscopic case, the alignment layer 20 is a flat structure before being rubbed and aligned.

[0027] Since the long axis and short axis of the branched chains of the material of the alignment layer 20 in the display substrate in this embodiment have different dielectric constants, the branched chains can be deflect...

[0033] Such as figure 2 As shown, this embodiment provides a display panel, including an array substrate 1, a cell-matching substrate 2, and a liquid crystal layer disposed between the array substrate 1 and the cell-matching substrate 2 (the cell-matching substrate 2 may be a color filter substrate). 30, wherein both the array substrate 1 and the box substrate 2 include an alignment layer 20, and the material of the alignment layer 20 of at least one of the array substrate 1 and the box substrate 2 is composed of a polymer with a branch; wherein, the The major and minor axes of the branches have different dielectric constants.

[0034] Since the long axis and short axis of the branched chains of the material of the alignment layer 20 of at least one of the array substrate 1 and the cell substrate 2 in the display panel of this embodiment have different dielectric constants, the branched chains can Deflection occurs under action. Therefore, when a voltage is applied to the e...

Abstract

The invention provides a display substrate, a display panel and a display device and belongs to the technical field of display. The display substrate comprises a substrate and an orientation layer arranged on the substrate, wherein the material of the orientation layer is composed of polymer having branched chains; dielectric constants of major axes and minor axles of the branched chains are different. Because the dielectric constants of the major axes and the minor axles of the branched chains of the material of the orientation layer in the display substrate are different, the branched chains can deflect under the action of an electric field. In this way, when the display substrate is applied to a liquid crystal panel, voltage is exerted on electrodes in the liquid crystal panel to generate the electric field so that while liquid crystal molecules deflect, the branched chains of the material of the orientation layer can deflect accordingly under the action of the electric field; of course, at the moment, the deflecting direction is identical to that of the liquid crystal molecules, in this way, molecule acting force between the material of the orientation layer and the liquid crystal moles is reduced, the response time of the liquid crystal molecules in the electric field is shortened, and the response speed of a liquid crystal display component is increased.

Description

technical field [0001] The invention belongs to the field of display technology, and in particular relates to a display substrate, a display panel and a display device. Background technique [0002] The basic structure of a Thin Film Transistor Liquid Crystal Display (TFT LCD) includes an array substrate (Array) and a color filter substrate (Color Filter, CF for short), which are filled with a liquid crystal layer. The liquid crystal cell ( Cell) structure. [0003] Wherein, a polymer alignment material (PI) is coated on both the array substrate and the color filter substrate and is in direct contact with the liquid crystal layer in the liquid crystal cell. The alignment material is aligned by the Rubbing process, so that the surface of the alignment layer has a certain pre-tilt angle. Generally, the pre-tilt angle is about 0-5°. It can generate a relatively large moment, so that the liquid crystal molecules can be deflected at a relatively fast speed, thereby improving th...
