Patent ID: 6909419

Claim:
A portable microdisplay system comprising: an active matrix liquid crystal display including an array of at least 75,000 pixel electrodes, the active matrix liquid crystal having an active matrix circuit having an array of transistor circuits formed in a first plane, each transistor circuit being connected to a pixel electrode in an array of pixel electrodes having an area of 200 mm 2 or less, and a counter electrode panel extending in a second plane that is parallel to the first plane; a light source positioned to illuminate the array of pixel electrodes; a lens positioned to receive an image formed on the active matrix liquid crystal display and that magnifies the image by at least a factor of two; a display circuit that generates images to be displayed on the liquid crystal display and connected to the active matrix liquid crystal display, the counterelectrode panel receiving an applied voltage such that the display circuit actuates the pixel electrodes to write an image, flashes the light source to illuminate the image, and switches the applied voltage to the counterelectrode to erase the image; and a data link that transmits data at a rate of speed of greater than 100 Mbytes per second in series between the display circuit computer and the active matrix liquid crystal display.
