Abstract
A video projector has first and second projector devices and a display screen. The first projector device is used to project a plurality of first image elements to be perceived by, for example, the right eye of a viewer. The second projector device is used to project a plurality of second image elements to be perceived by, for example, the left eye of the viewer. The first image elements from the first liquid crystal projector device and the second image elements from the second liquid crystal projector device are projected on the display screen. The size of image elements projected on a liquid crystal display panel is adjusted so that the adjacent image elements do not overlap with each other. As a result, interference between adjacent picture elements is substantially eliminated and thus the image quality is improved.
