Abstract:
1. A light source device, comprising: a first color light source unit configured to form and emit a first color division light X a second color light source unit configured to form and emit a first color division light Y a third color light source unit configured to form and emit a first color division light Z a first color synthesizing optical element configured to synthesize light from the optical path xI, the optical path yI, and the optical path zI into a first synthesized light and emit the first synthesized light; a second color synthesizing optical element configured to synthesize light from the optical path xII, the optical path yII, and the optical path zII into a second synthesized light and emit the second synthesized light; a first spatial modulation element configured to receive the first synthesized light and emit a first light image; a second spatial modulation element configured to receive the second synthesized light and emit a second light image, the second spatial modulation element being driven in conjunction with the first spatial modulation element; an optical image synthesizing mechanism configured to synthesize the first light image and the second light image into a synthesized light image and to emit the synthesized light image; and a synthesized light image projection element configured to project the synthesized light image; wherein: each frame of the synthesized light image is divided into a plurality of time periods and in each of the plurality of time periods two or more of the color light X, the color light Y, and the color light Z are configured to be projected simultaneously.
