Progress of liquid crystal materials for VA-TFT;

The developing of photorefractive liquid crystal material;

Relationships of LCD TV among response time,operating voltage and liquid crystal materials parameters are introduced under three modes including vertical alignment(VA)mode,in plane switching(IPS)mode and twisted nematic(TN)mode.

This paper presents an improved process for the preparation of the novel liquid crystal 5-propyl2-(3,5-difluorophenyl)pyrimidine.

By using Nd∶YAG mode locked pulse laser (λ=532 nm, τ 0=35 ps), the third order nonlinear optical susceptibility χ (3) , and time response properties of liquid crystals containing Schiff base and Naphthalimide are measured with forward degenerate four wave mixing (DFWM).

A new method for the determination of cations on the organic molecule in the liquid crystal materials by ultraviolet(UV) photolysis ion chromatography was developed.

The total synthesis of the nematic liquid crystal material 4-[2-(trans-4′-propylcyclohexyl)ethyl]-1-fluorobenzene through eight steps was reported.

In this paper, synthesis and research of ferroelectric liquid crystal materials were reviewed in recent years in China and the problem about its application in display field was also discussed here.
