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.
Two kinds of polymerizable liquid crystal compounds have been prepared successfully in the paper, one is tolan-type liquid crystal compound, another is a phenylcyclohexanethyl liquid crystal compound.
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.
The only way to make a real-time kinoform is to use the liquid crystal spatial light modulator.And the kinoform is valuable to optical information processing and optical measurements.
Also some liquid crystal displays depend on, demonstrated body itself which the modulation outside light realizes nonluminous, does not stimulate the eye, is not easy to be weary and so on the merit.
