Abstract
A projector of the present disclosure includes a light source, and a light modulator, the light modulator has a liquid crystal panel, a multi-lens array entered by first, second, third lights, and a light refractor array. The liquid crystal panel has a plurality of pixels and each of the plurality of pixels has first, second, third sub-pixels. The multi-lens array has a plurality of lenses entered by the first, second, third lights. The light refractor array has a first light refractor over a boundary between the first, second pixels and a second light refractor over a boundary between the first, third pixels. The first light from the first pixel and the third light from the second pixel enter the first light refractor, and the third light from the first pixel and the first light from the third pixel enter the second light refractor.
Claims7
A projector comprising:
- a light source device emitting a light containing a first color light, a second color light, and a third color light different in color from one another;
- a light modulator modulating the first color light, the second color light, and the third color light emitted from the light source device based on an image signal;
- and
- a projection optical device projecting the light output from the light modulator, wherein
- the light modulator has
- one liquid crystal panel,
- a multi-lens array provided at a light incident side of the liquid crystal panel and respectively entered by the first color light, the second color light, and the third color light emitted from the light source device at different angles, and
- a light refractor array provided at a light exiting side of the liquid crystal panel,
- the liquid crystal panel has a plurality of pixels containing a first pixel, a second pixel, and a third pixel,
- each of the plurality of pixels has
- a first sub-pixel entered by the first color light collected by the multi-lens array,
- a second sub-pixel placed adjacent to the first sub-pixel in a first direction and entered by the second color light collected by the multi-lens array, and
- a third sub-pixel placed adjacent to the second sub-pixel in the first direction and entered by the third color light collected by the multi-lens array,
- the multi-lens array has a plurality of lenses provided to correspond to each of the plurality of pixels and respectively entered by the first color light, the second color light, and the third color light at different angles,
- the light refractor array has
- a first light refractor placed over a boundary between the first pixel and the second pixel adjacent to the first pixel in the first direction of the plurality of pixels, and
- a second light refractor placed over a boundary between the first pixel and the third pixel adjacent to the first pixel at an opposite side to the first direction,
- the third color light emitted from the third sub-pixel of the first pixel and the first color light emitted from the first sub-pixel of the second pixel enter the first light refractor, and
- the first color light emitted from the first sub-pixel of the first pixel and the third color light emitted from the third sub-pixel of the third pixel enter the second light refractor.
