Abstract
The laser-beam addressed liquid crystal display is very attractive because of its very versatile display functions. Liquid crystal thermo- and electrothermo-optic effects on which the display functions are based are reviewed. Various display principles reported in the past are described, and technology to improve the write-in speed is surveyed. Recent display systems which can be used in practical fields are summarized. The paper emphasizes the liquid crystal aspects rather than the display electronics and system features.
