Embodiment Construction

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present invention.

[0024] An embodiment of the present invention provides an alignment film, which is obtained by reacting a dianhydride compound, a branched diamine compound, and a highly conjugated polymer material. In the embodiment of the present invention, by modifying the alignment film material of the prior art, an alignment film material with low volume resistance performance can be obtained, so that the residual DC bias voltage in the display panel can be quickly released, thereby improv...

Abstract

The invention provides an alignment film. The alignment film is obtained by reacting a dianhydride compound, a diamine compound with a branched chain and a highly conjugated polymer material. By doping the highly conjugated polymer material into a conventional alignment film material, the body resistance of the alignment film material can be reduced, so that the residual direct-current bias voltage in a liquid crystal panel can be quickly released, and the technical effect of improving residual images is achieved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an alignment film, a preparation method thereof, and a display panel. Background technique [0002] As the market has higher and higher requirements for the quality of panels, the design of panels has become more and more complex, and the requirements for reliability of panels have also become higher and higher. Reliability is a very important indicator of panels, and the main factors affecting reliability are It is an afterimage. [0003] During the reliability test, due to the aggregation and movement of ions, a DC bias voltage is generated, resulting in different effective voltages in different areas, which eventually leads to differences in brightness in different areas, resulting in afterimages, which affect the quality of the panel. Therefore, it is necessary to improve this defect. Contents of the invention [0004] An embodiment of the present invention provides an a...
