Abstract
An optical and projection system for viewing images produced on an active matrix slide is disclosed. An embodiment of the viewing system includes a graphic user interactive system in which images generated by a computer are controlled by a remote and are viewed on a viewing surface. The remote can be incorporated into the protective endcap of the active matrix slide. The light absorbed by the thin-film transistors of the active matrix can be reduced by tilting the more heavily shielded side of the thin-film transistors towards the light source. The invention further comprises an active matrix having an array of microlenses positioned to receive light from a light source. Each microlens converges and delivers light in a uniform or desired distribution to a corresponding pixel.
