PORTABLE MICRODISPLAY SYSTEM
First Claim
1. A portable microdisplay system comprising:
- an active matrix liquid crystal display including an array of at least 75,000 pixel electrodes, the array of pixel electrodes having an active area of less than 200 mm2;
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; and
a data link that transmits data at a rate of speed of greater than 100 Mbytes per second in series for at least a portion between the display circuit computer and the active matrix liquid crystal display.

Abstract
An active matrix color crystal display has an active matrix circuit, a counterelectrode panel and an interposed layer of liquid crystal. The active matrix display is located in a portable microdisplay system that has a display computer that generates images to be displayed on the liquid crystal display and connected to the active matrix liquid crystal display. A data link transmits data at a rate of speed of greater than 200 Mbytes per second in series for at least a portion between the display computer and the active matrix liquid crystal display. In a preferred embodiment, the display system has a randomizing device that alternates the amplifier through which an analog video signal passes.
