DISPLAY APPARATUS
First Claim
1. A compact display apparatus for providing virtual 3D images comprising:
- an enclosure;
a LED illumination based electronic display device;
a partially transparent and partially reflective viewing surface; and
an interference filter screen,wherein the enclosure houses the LED illumination based electronic display device, the interference filter screen and the partially transparent and partially reflective viewing surface,wherein the interference filter screen is positioned close to the surface of the LED illumination based electronic display device,wherein the LED illumination based electronic display device projects a primary real image through elite the interference filter screen,wherein the primary real image projected through the interference filter screen is optically transmitted onto the partially transparent and partially reflective viewing surface,wherein the partially transparent and partially reflective viewing surface reflects a secondary virtual 3D image perceivable on the opposite side of the partially transparent and partially reflective viewing surface to the LED illumination based electronic display device,wherein the reflected secondary virtual 3D image is without interference pattern, andwherein removal of the interference pattern on the partially transparent and partially reflective viewing surface is achieved by the interference filter screen.

Abstract
The present invention relates to a compact display apparatus providing similarly sized but much brighter virtual 3D images to a viewer, the apparatus comprising an enclosure; LED illumination based electronic display device; partially transparent and partially reflective viewing surface; and contrast/interference filter screen. The enclosure houses the LED illumination based electronic display device, filter screen and the partially transparent and partially reflective viewing surface. The filter screen is positioned close to the surface of the LED illumination based electronic display device. The LED illumination based electronic display device projects a primary real image onto the filter screen and is optically transmitted onto the partially transparent and partially reflective viewing surface. The partially transparent and partially reflective viewing surface reflects a secondary virtual 3D image perceivable on the opposite side of the partially transparent and partially reflective viewing surface to the LED illumination based electronic display device.

39. A method for producing an animated production of 3D illusion in a second remote location comprising:
-
transmitting or broadcasting an image of a lit person or object which is filmed against a selected background in a separate location; and generating by use of rapid image processing techniques to generate an alpha channel image combined with online hosting of the virtual 3D image of the person or object in the separate location(s) thereby broadcasting an image for the immediate playback at the second location. - View Dependent Claims (46)
