[Study on electro-optical performance of frequency driven liquid crystal light valve].
The electro-optical characteristic and principle of frequency-driven liquid crystal light valve were discussed and analyzed. Under different electric field frequency and certain AC voltage, the electro-optical characteristic of frequency-driven TB3639 liquid crystal light valve was measured. The results show that it can display gray scale in visible light region, and it can not only display black and white, but also can display different gray scale. The influence of frequency-driven way to the transmission spectrum change tendency of different wavelength in visible light is approximately same, which will avoid high chromatism in application. The new frequency-driven liquid crystal light valve can improve display quality of liquid crystal display device. It will develop new application of liquid crystal display device and has practical application value.
