THERMO-COMPENSATED LIQUID-CRYSTALLINE DISPLAY Russian patent published in 2008 - IPC G02F1/13 G02F1/133 

FIELD: engineering of systems for displaying optical information, namely: design of liquid-crystalline displays in aviation realization thereof.

SUBSTANCE: in claimed construction of liquid-crystalline display an additional or main heating system is made in form of frame, along each side of which heating elements are provided which are in thermal contact with edges of liquid-crystalline cells, which are separately powered by control block depending on distribution of temperature across the surface of liquid-crystalline cells. Distribution of temperature is controlled by any known method. Described system maintains temperature of liquid-crystalline cell edges at a level not below the temperature of the hottest point of screen. The frame and peripheral part of liquid-crystalline cell walls create stretching forces, which influence the remaining part of walls, resulting in increased resonance frequencies of liquid-crystalline cell oscillations and preventing warping, layering and depressurization.

EFFECT: expanded capabilities of liquid-crystalline displays due to excluded mechanical strains in layers of liquid-crystalline cells and, as a result, prevented warping, layering and depressurization of liquid-crystalline cells.
