OPTICAL SYSTEM FOR DISPLAY PANEL

摘要

An ultrathin panel comprised of stacking a plurality of glass sheets, which may be coated with a transparent cladding substance or may be uncoated, fastened together using an epoxy or adhesive. A coupler (16) is bonded to the inlet face (20) of the stack. A housing having a light generator (12) which is optically aligned with the coupler. The light generator is preferably placed parallel to and proximate the inlet face, thereby allowing a reduction in depth of the structure. An optical system comprises an image source (110), an imaging element (120) for creating an image of an object in an intermediate image plane, an anamorphic element (130) for reducing anamorphic distortion of the image, and a telecentric element (140) for reducing keystone-type distortion of the image.
