Video display device with spatial light modulator

Abstract

A spatial light modulating-type video display device is provided which has excellent color reproductivity of a video even when a light source is used which emits light having chromaticity coordinates of each of three primary colors (R, G, and B) being different from those designated by specifications of colorimetry. The video display device has a red color light source being driven by the red color light source driving circuit and emitting red color light being, a green color light source being driven by the green color light source driving circuit and emitting green color light, and a blue color light source being driven by the blue color light source driving circuit and emitting blue color light, spatial light modulators each performing spatial modulation on red color light, green color light, and blue color light, an image synthesis optical system to synthesize spatially modulated light, a selecting circuit to select orders of video signals to modulate incident light in each spatial light modulator, and a control circuit to control driving timing and/or driving current of the light sources in each of the spatial light modulators and timing of selection in the selecting circuit.
