Paper Abstract

Projection display in today's market is dominated by cathode ray tubes (CRTs). Further progress in this mature CRT projector technology will be slow and evolutionary. Liquid crystal based projection displays have gained rapid acceptance in the business market. New technologies are being developed on several fronts: (1) active matrix built from polysilicon or single crystal silicon; (2) electro- optic materials using ferroelectric liquid crystal, polymer dispersed liquid crystals or other liquid crystal modes, (3) micromechanical-based transducers such as digital micromirror devices, and grating light valves, (4) high resolution displays to SXGA and beyond, and (5) high brightness. This article reviews the projection displays from a transducer technology perspective along with a discussion of markets and trends.
