Abstract

The invention discloses a composite liquid crystal film capable of being rapidly self-repaired and a preparation method thereof. The composite liquid crystal film capable of being rapidly self-repaired comprises an anti-ultraviolet PET transparent conductive film with one side plated with ITO, a polymer self-repairing material liquid crystal composite system thin layer and a PET transparent conductive thin film with one side plated with ITO, and the three layers are connected from top to bottom. According to the composite liquid crystal film capable of being rapidly self-repaired, the wear resistance and the service life of the film are improved; meanwhile, the ultraviolet aging resistance of the film is greatly enhanced; and the contrast ratio and the response time of a writing board are greatly improved, and favorable conditions are created for self-repairing of a polymer network. In addition, the polymer network in the film can be self-repaired after being damaged. The composite liquid crystal film capable of being rapidly self-repaired has excellent stability and long service life, the production process is simple, the manufacturing cost is low, and industrial production is facilitated.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a fast self-repairable composite liquid crystal film and a preparation method thereof. Background technique [0002] In recent years, with the rapid development of liquid crystal display technology, various liquid crystal display devices have been widely used in all aspects of life. Liquid crystal writing board has many advantages such as convenient writing, clear pattern, fast response speed, low power consumption, etc., and overcomes the shortcomings of traditional blackboards such as easy generation of dust, time-consuming and labor-intensive erasure, and has been widely used in schools, life, Office and other fields. [0003] However, during the use of the writing board, it is inevitable that the polymer network will be damaged due to accidental collision, aging and other factors, which will affect its stability and service life. The top priority in the resea...
