A full‐color TFT‐LCD with a polymer‐dispersed structure

Abstract— A direct‐view TFT‐LCD with a wide viewing angle, which uses a polymer‐dispersed liquid‐crystal panel and a pair of polarizers, is proposed. The device has a vertical viewing‐angle range of 120°, with a contrast ratio over 5:1 without display‐image reversal. This is about three times the twisted‐nematic display's viewing‐angle range.
