Problems solved by technology

[0003] For flexible thin film transistor liquid crystal displays, liquid crystal materials are required. The liquid crystal material itself has fluidity, but when the substrate is bent, the liquid crystal material will flow due to uneven pressure, which will cause problems such as poor alignment and light leakage of the liquid crystal material.

Embodiment Construction

[0025] The present invention will be described in detail below with reference to the drawings and embodiments.

[0026] The invention provides a liquid crystal medium mixture for a liquid crystal display panel, which comprises a liquid crystal material, a photoinitiator, and at least one polymerizable monomer that can undergo polymerization under ultraviolet light irradiation.

[0027] The liquid crystal material is a nematic liquid crystal material with a negative dielectric anisotropy constant. E.g:

[0028]

[0029]

[0030] At least one of, where R 1 , R 2 Is an alkyl chain, for example: C n H 2n+1 , OC n H 2n+1 , C n H 2n , OC n H 2n Wait.

[0031] In other specific embodiments, the structural formula of the liquid crystal material is:

[0032]

[0033] At least one of them.

[0034] The material of the photoinitiator can be but not limited to commercial photoinitiators, for example:

[0035]

[0036] Wherein, the mass of the photoinitiator accounts for 0.02-0.07% of the total mas...

Abstract

The invention discloses a liquid crystal medium mixture, comprising a liquid crystal material and at least a polymeric monomer, wherein the polymeric monomer can generate a polymerization reaction under the illumination of ultraviolet light, and, when illuminated by first ultraviolet light, the polymeric monomer generates the polymerization reaction, and a blocking wall is formed inside a liquid crystal display panel, so as to limit the flow of the liquid crystal material. The invention also discloses the liquid crystal display panel. According to the liquid crystal medium mixture disclosed by the invention, the flow of the liquid crystal material can be limited effectively, and therefore the phenomena of undesirable orientation, light leakage and the like caused by the bending of the liquid crystal display panel are avoided effectively.

Description

Technical field [0001] The invention relates to the field of display technology, in particular to a liquid crystal medium mixture and a liquid crystal display panel. Background technique [0002] Flexible display (flexible display) technology is one of the most active research directions in the field of electronic information in recent years, and it is also one of the important directions for the development of the electronic information industry in the future. Flexible displays include flexible thin-film transistor liquid crystal displays (Flexible TFT-LCD), flexible organic light-emitting displays (Flexible OLED), etc., which are lightweight, bendable, foldable and even rollable, and are usually used in mobile phones, electronic paper, etc. [0003] For flexible thin film transistor liquid crystal displays, liquid crystal materials are required. The liquid crystal materials have fluidity. However, when the substrate is bent, uneven pressure causes the liquid crystal materials to ...
