FIELD: electricity.
SUBSTANCE: invention refers to projection devices. The device comprises solid-state light source, rotating luminiferous plate, which converts excitation light from the source to luminescent light. Liquid-crystal light modulator modulates light from the rotating luminiferous plate. Projection optical system projects modulated light to the screen and control device controls solid-state light source and rotating luminiferous plate.
EFFECT: preventing flickering invoked by rotation of luminiferous plate.
