Resolution-Enhancing Device Based on Vertically Aligned FLC for Projection Displays

Abstract

A new resolution-enhancing device has been developed based on a novel structure and a unique principle of operation, which shifts the optical path of projected light from pixel arrays by a half pitch at a fast switching speed. The device has a Vertically Aligned Ferroelectric Liquid Crystal (VA-FLC) layer and Multiple Line-shaped Transparent Electrodes (MLTE) that apply a uniform electric field to the VA-FLC layer. These features provide good optical performance in this optical path shift device and produce excellent projection images.
