Abstract
An image projector apparatus for producing an image for display on a projection screen. The image projector apparatus includes a plurality of first microlenses each receiving light from a light source, a liquid crystal display having a plurality of pixels each adapted to receive light from a respective one of the first microlenses and provide respective image light therefrom in response to image information supplied thereto, a plurality of second microlenses each receiving the image light from a respective one of the pixels and projecting parallel image light therefrom, and a projection lens receiving the parallel image light from each of the second microlenses and projecting the same onto the projection screen. The projection lens may be moved or positioned such that an optical center axis thereof is offset from an image center axis of the liquid crystal display so as to eliminate or minimize a so-called keystone distortion.
