Light Valves Enable 110-in. High-Definition Display

Facebook X LinkedIn Email
A team at NHK and Seikei University, both in Tokyo, has reported the development of a 110-in., color high-definition projection display that employs polymer-dispersed liquid crystal light valves. The researchers described the display in the Jan. 1 issue of Applied Optics. The device features a light valve for each of the red, green and blue channels. Each light valve features nematic liquid crystal in a three-dimensional polymer matrix. Irradiating a boron-doped, hydrogenated amorphous silicon photoconductive film on the back side of the valve with the information to be projected orients...Read full article
