Abstract
A display adapted to be helmet-mounted or used for projecting and having the multi-mode capability of full three-primary color displays; gray scale or halftones; stereo imagining; image processing; split-screen operation; blink comparator; see-through, heads-up viewing; and night-vision intensification combined with alpha-numerics. A bulb in a reflective housing illuminates a plastic diffusion screen to create a light beam. An electronic alterable, random-access storage display chip is placed in line with the emerging beam. The display chip comprises a film sandwich configuration consisting of a sheet polarizer, a magneto-optic chip with addressible alterable areas, and a sheet polarization analyzer. Signals received from a radio link are applied through a cable and connectors to the chip. By driving the chip as a function of the desired display, the display is impressed on the beam of light which may then be split and passed through appropriate focusing lenses for viewing or projected. Multiple beams, multiple display chips, and multiple layered chips with filtering are employed to create various operating modes.
