The invention relates to a microdisplay system that utilizes a small high resolution active matrix liquid crystal display with an illumination system and a magnifying optical system to provide a hand held communication display device. The system can employ an LED illumination system and cellular communication or processor circuits within a compact housing to provide communication devices such as pagers, telephones, televisions, and hand held computer devices with a compact high resolution video display.

Microdisplay for portable communication systems

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.

Portable microdisplay system

The invention relates to a microdisplay system that utilizes a small high resolution active matrix liquid crystal display with an illumination system and a magnifying optical system to provide a viewfinder in a electronic image record system such as a digital camera or video camera. The matrix display can be transmissive or reflective using sequential lighting. The system can use an alternating common voltage which allows reduced power consumption. In addition an internal heating system in the display allows the system to be used at low temperatures.

A method of fabricating a display system includes bonding a silicon substrate to a second substrate with an insulating layer. The silicon substrate is thinned to form a thin film silicon-on-insulator (SOI) structure. A matrix display circuit is formed with the SOI structure. A light shield pattern is formed over regions of the matrix display circuit. A light source, the matrix display circuit and a magnifying lens are positioned within a display housing such that light from the light source is directed onto the display and an image on the display is magnified by the lens for viewing by a user.

Method of fabricating a matrix display system

An active matrix color sequential liquid crystal display has an active matrix circuit, a counterelectrode panel and an interposed layer of liquid crystal. The active matrix circuit has an array of transistor circuits formed in a first plane. Each transistor circuit is connected to a pixel electrode in an array of pixel electrodes having a small area. The counterelectrode panel extends in a second plane that is parallel to the first plane, such that the counterelectrode panel receives an applied voltage. The liquid crystal layer is interposed in a cavity between the two planes. In a preferred embodiment, an oxide layer extends over the pixel electrode array. The oxide can have a first thickness in a peripheral region around the array of the pixel electrodes and a thinner second thickness in a pixel electrode region extending over the array of pixel electrodes.

Low power active display system

An active matrix display panel is operated by a color sequential system to form color images. A color generator is disposed between a light source and the display panel for sequentially providing red, green and blue light. A color sequential drive circuit controls the color generator and the pixels of the display panel. The color generator is preferably a multi-stage multiple wavelength blocking filter incorporating fast switching surface stabilized liquid crystal cells.

Wireless telephone display system

A housing is mountable on a carousel slide projector. The housing contains a movable light valve slide assembly that is coupled to a video signal source. The light valve slide assembly is movable between a position within the housing and a position outside the housing. When mounted on the slide projector, the light valve slide assembly can be moved into the projection chamber of the slide projector. The video signal source transmits a video signal to the light valve slide assembly, where the video signal is converted to a drive signal to actuate pixels on the light valve. The light valve thus generates a video image that is projected onto a viewing surface. Preferably the light valve is an active matrix liquid crystal display.
