Active matrix lcd image projection system

Abstract From the Canadian patent

An active matrix LCD light valve between crossed polarizers, utilizing individual transistors to control each "pixel area" of the LCD with optically shielded "dead spaces" between pixels to eliminate electric field crosstalk and non-information-bearing light bleed through is illuminated, with a bright independent light source which creates a video image, projected via specialized projection optics onto an internal or external screen without distortions regardless of the angle of projection onto the screen. Use of heat sinks IR, reflective coatings, heat absorbing optics optional fluid, and, a thermistor controlled pixel transistor bias voltage injection servo circuit stabilizes image …
