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.

与液掺杂后这类染料表现出许多良好的性,如具有宽液的视角、增亮度等。

Many parameters are required to describe their performance, which is transmission ratio, extinctivity ratio, angle of view field, splitting angle, etc.
