LIQUID-CRYSTALLINE DISPLAY ELEMENT Russian patent published in 2006 - IPC G02F1/133 

FIELD: indication equipment.

SUBSTANCE: element contains three serially positioned liquid-crystalline cells, inlet mask with slits, raster capacitor, raster objective, outlet mask with slits, position of which is synchronized with position of slits of inlet mask and considers distance from liquid-crystalline layer to slits of outlet mask. In each one of three cells one of three primary colors is formed due to electrically controllable diffraction grid, formed in liquid-crystalline layer when control voltage is fed onto it.

EFFECT: element has high brightness and independent, spectrally clean primary colors.
