Liquid crystal optical orientation method

Abstract

The invention belongs to the technical field of liquid crystal display equipment, and particularly relates to a liquid crystal optical orientation method. Coumarin photosensitive group organic polymer is adopted to replace polymer orientation materials, an optical orientation layer can be manufactured at normal temperature, a flexible liquid crystal display device applied to a liquid crystal displayer is manufactured, the problem that the thermal tolerance of a flexible substrate is limited is solved fundamentally, the constraint of the process link requirement on the production process is avoided, and the material can be applied to the orientation mode of the flexible liquid display device.

Description

technical field [0001] The invention belongs to the technical field of liquid crystal display devices, and in particular relates to a liquid crystal photo-alignment method. Background technique [0002] The development of display has gone through great development from CRT to PDP to LCD and OLED. In order to meet the increasingly diversified needs of society, display devices are constantly undergoing innovations in various aspects. Higher requirements are put forward for portability and thinness. In the process of continuous transformation, social needs continue to push display devices to develop in the direction of flexible displays. Flexible display has increasingly become an important development direction, and various theories based on the realization of flexible display have emerged as the times require. However, traditional techniques have been unable to meet the development needs of flexible display devices. In particular, the assembly line process guided by Roll-to...

AI Technical Summary

Problems solved by technology

The main problem is that the parallel alignment effect of liquid crystal molecules is unstable, and the cis structure will spontaneously transform into a more stable trans structure.

However, the film in this invention is irradiated with polarized light, which will cause unstable parallel alignment of liquid crystal molecules; the photodecomposition products wrapped in the liquid crystal cell will cause adverse effects on the liquid crystal
