Slim optical projection system and image display apparatus employing the same

摘要

A slim optical projection system and an image display apparatus employing the same. The optical projection system includes: a relay lens group to produce an intermediate image from an image created by a display and to generate a first distortion in the intermediate image, a projection lens group to enlarge and project the intermediate image that passes through the relay lens group and to generate a second distortion in the projected image, and a reflector to reflect the image enlarged by the projection lens group to a screen at a wide viewing angle. The first and second distortions are used to compensate for a third distortion caused by the reflector
