Abstract

Liquid crystal light modulators (LCLMs) are classified into optical writing type and electrically writing type. Both types are useful for optical and electrical information sources. Recently, the electrical writing type has made progress as liquid crystal displays (LCDs) for laptop computers and pocket television. These LCDs are also classified into direct matrix type and active matrix type by using thin-film transistors or nonlinear diodes. In this presentation, the fundamental design concept and characteristics of these LCLMs are discussed in detail.
