LIQUID CRYSTAL SCREEN Russian patent published in 2007 - IPC G02F1/13 G02F1/1335 

FIELD: optics.

SUBSTANCE: liquid crystal screen can be used in systems for representation of optical data. At reduction in thermal load onto liquid crystal cell of liquid crystal screen at high levels of illumination, one or both polarizers of liquid crystal cell are doubled by additional polarizers, which have the same direction in plane of polarization and are disposed to have space in relation to first polarizers. There is transparent thermal insulator or cooling agent in space.

EFFECT: reduced thermal load at high levels of illumination.
