Cholesteric Reflective Displays

  • Reference work entry
Handbook of Visual Display Technology

Abstract

Thin films of cholesteric liquid crystal can be electrically switched at modest voltages into either a reflecting state that provides a specific color or an almost transparent state that appears black when a black absorber is placed behind the display. Both states are stable over time. Many display variations, using glass and flexible plastic substrates, have been made using this general effect to produce a wide range of display devices.
