Abstract
A color display apparatus includes a mechanism for storing images on a plurality of partially transparent sheets. A drive mechanism brings one sheet into viewing position as another sheet simultaneously withdraws in the same direction to produce a smooth dissolve of the projected image. Silk screened stripes of material on the sheets prevent the sheets from rubbing against each other and harming the graphic information and otherwise prevent mechanical interference between the sheets. By contouring the surface of the screen, it is possible to create a three dimensional image by illuminating the rear surface with a television screen or other image storage or producing device. It is further possible to obtain a digitized color display by placing a fluorescent bulb behind the cells of the digitizing screen with each cell containing at least one liquid crystal element and at least one color filter element and then selectively controlling the liquid crystals to produce the digitized color display. The digitizing screen can also be used as an image conversion tool by illuminating original art work on the rear face of the digitizing screen and tracing the digitized image thereof from the front face of the screen.
