The photoemissions are showed after dichroitic azo dyes doping with liquid crystal,such as widening angle of view, improving light in display and so on.

与液晶掺杂后这类染料表现出许多良好光电特性,如有液晶视角、增加度等。

Dichroitic azo dyes play an important role in the color liquid crystal displays because of their characteristic structure and the ability of being chemical modified.
