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.

摘要： Provided are a method and apparatus for compensating display distortion generated when the image is formed using the operational characteristic of a scanner. The method for compensating a display distortion in a display system includes: dividing a sync section where image data is output into a plurality of sections; setting a clock speed of the image data for each of the sections based on an operational characteristic of a scanner; and outputting the image data at a different clock speed for each divided section, the different clock speed reflecting a set clock speed for each divided section.
