Kind Code:
A1
Abstract:
A display device, comprising a light source apparatus, a first spatial light modulator, a second spatial light modulator, a first light recovery apparatus, and a second light recovery apparatus, the light source apparatus being used for emitting a light having a first color, a fluorescence having a second color, a supplemental light having the second color, a fluorescence having a third color, and a supplemental light having the third color; the first spatial light modulator is used for modulating the light having the first color to generate an image light having the first color and modulating the fluorescence having the second color and the supplemental light having the second color to generate an image light having the second color and a non-projection light; the second spatial light modulator modulates the fluorescence having the third color and the supplemental light having the third color to generate an image light having the third color and a non-projection light; the first light recovery apparatus recovers the light having the first color and the supplemental light having the second color in the non-projection light generated by the first spatial light modulator to the first spatial light modulator for reuse; the second light recovery apparatus recovers the supplemental light having the third color in the non-projection light generated by the second spatial light modulator to the second spatial light modulator for reuse.
