摘要:
A color picture is projected onto a liquid crystal display panel and becomes visible, in color, at those areas of the panel at which the liquid crystal is concurrently excited by the application of an electric field. A ''''moving'''' picture is simulated by selectively removing (or applying) the electric field from (or to) different areas of the panel during successive time intervals.
