Abstract:
1. An image display system having direct and projection viewing modes of operation, comprising an image display device including: a transportable housing having first and second light transmission apertures formed therein and aligned with each other; a display panel assembly including a rear housing panel for covering a substantial portion of said rear light transmission aperture during said direct viewing mode, and having an interior surface; a light reflective surface disposed on said interior surface of said rear housing panel; a portable light projection device including wherein during said direct viewing mode, light is produced from said light producing means and is reflected within said light guiding panel and scattered by said light diffusing structure, and a portion of said scattered light is transmitted through said first light guiding surface and said programmable spatial light mask, whereupon said transmitted light is spatial-intensity modulated so as to form a light image on the display surface of said programmable spatial light mask; and wherein during said projection viewing mode, light is produced from the light producing device and is transmitted through said thin lens panel and said programmable spatial light mask, whereupon said transmitted light is focused and spatial-intensity modulated so as to form a light image on a viewing surface disposed at a distance from said programmable spatial light mask.
