PROJECTION DISPLAY APPARATUS |
摘要 |
A projection display apparatus includes: an illumination optical unit which emits beams; an image display element which modulates the beams according to image information; a spatial-beam changing unit which changes spatial positions of the beams emitted from the illumination optical unit; and a uniform-beam distribution unit, disposed between the spatial-beam changing unit and the image display element, which uniformly distributes the beams. The spatial-beam changing unit includes a moveable prism, a movement of which changes the spatial positions of the beams emitted therefrom.
