Assignee:

Kopin Corporation - Taunton MA

International Classification:

G09G 3/36

US Classification:

345102, 345 88, 345101

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.

International Classification:

G02F 1/1343
G02F 1/1339

US Classification:

349139, 349155

Abstract:

A liquid crystal display comprises a display panel that includes at least one pixel transistor, at least one pixel electrode in electrical communication with the pixel transistor, at least one common electrode, and a liquid crystal material between the pixel electrode and the common electrode. The pixel transistor includes a thin film layer of essentially single crystal silicon that has a thickness in a range of between about 100 nm and about 200 nm. The pixel electrode has a thickness in a range of between about 5 nm and about 20 nm. The common electrode has a thickness of between about 50 nm and about 200 nm.

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. The image is written to the the display therein causing the liquid crystal to move to a specific image position. A light source is flashed to illuminate the display. The pixel electrodes are set to a specific value to cause the liquid crystal to move towards a desired position. The process of writing, flashing, and setting the electrode intensity value to reorient the liquid crystal to produce an image is repeated. Portable system can include a digital camera, cellular telephone, camcorder, heads up display, instant print camera, pager,
