发明名称 CORRECTING OPTICAL SYSTEM FOR FLAT-PANEL DISPLAYS
摘要 PROBLEM TO BE SOLVED: To provide a method for correcting distortions of an image, on a flat panel display where an image is projected to a tapered transparent slab from a microdisplay. SOLUTION: A flat panel projection display includes a taper-shaped and transparent slab waveguide 1; a projector 2 which can make an image incident inside the thick end part of a slab; a translucent screen 3 on the surface of the slab which can see a display; and a spacer which holds the screen 3 with its separation from the slab so that light emitted from the surface of the slab may be spread so as to cover the area of the screen 3. According to this, in other cases, the strip of a gap or blank existing in a point at which luminous flux is reflected from the back surface of the tapered waveguide 1 is removed.
