LIQUID-CRYSTALLINE SCREEN Russian patent published in 2006 - IPC G02F1/13 G02F1/1335 G03B21/16 

FIELD: engineering of systems for displaying optical information.

SUBSTANCE: liquid-crystalline screen is proposed, which has gaps for coolant between walls of liquid-crystalline cell and polarization changers. For pumping air through gaps, draining ventilator is used, because air during that expands in area of gap and cools down more. To decrease thermal effect on liquid-crystalline cell from external radiation, it is proposed to apply anti-reflective cover to surface of liquid-crystalline cell. Effect of infrared radiation on liquid-crystalline cells from heated polarization changers is weakened by creating a layer with high refraction coefficient, included in composition of anti-reflective cover, made of material with high conductivity.

EFFECT: possible use of liquid-crystalline screen under heavier thermal conditions, for example, in aviation, due to circulation of coolant and due to prevention of contact of liquid-crystalline cells with polarization changers, heating up during operation.
