A 21-in. Field Sequential High - Resolution CRT Using Liquid Crystal Color Shutter

摘要

Feasibility of a color shutter using ferroelectric liquid crystal polymer panel and a field sequential ultra high - resolution CRT with the color shutter as a color field - switching device was studied. The color shutter consists of ferroelectric liquid crystal polymer panels and color polarizers. First, evaluation indices of the color shutter, such as the color gamut, the average transmittance and the white chromaticity shift, were formulated, and the simulation of evaluation indices was examined, where the spectral transmittance characteristics of the polarizer were changed in steps.
