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

Alignment of an imaging area of a display with a user's eye provides optimum image quality for the user. Typically, a display is formed of a display panel encased within a carrier. The carrier is used to mechanically align the display panel within a device housing. However, the display panel must first be aligned within the carrier and the carrier and display combination aligned within a device housing. By utilizing the display panel without the carrier, one alignment step is removed from the installation process. Placing the display panel within a housing having an alignment device ensures proper alignment of an imaging area of the display panel with an opening of the housing.

Display housing with a display alignment device

A display module includes a display, a first polarizer and a second polarizer. The polarizers can be located at a distance from the image plane of the display to remove the visibility of optical defects located within the polarizer or between the polarizer and display. The display module can also include at least one lens for magnifying the image produced by the display. The display module can also include a backlight having a first polarizer, a second polarizer and a light source.

Polarizer removal in a microdisplay system

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.

An apparatus and method to delay a field of video by one row in a two field frame to reduce DC build-up or stick caused by textual image.

Timing of fields of video

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.

Color display system for a camera

A multi-layered structure is fabricated in which a microprocessor is configured in different layers and interconnected vertically through insulating layers which separate each circuit layer of the structure. Each circuit layer can be fabricated in a separate wafer or thin film material and then transferred onto the layered structure and interconnected.

Three dimensional processor using transferred thin film circuits

The present invention relates to methods of fabricating pixel electrodes ( ) for active matrix displays including the formation of arrays of transistor circuits in thin film silicon ( ) on an insulating substrate and transfer of this active matrix circuit onto an optically transmissive substrate ( ). An array of color filter elements can be formed prior to transfer of the active matrix circuit that are aligned between a light source for the display and the array of pixel electrodes to provide a color display.

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 or card reader devices with a compact high resolution data and/or video display.

Display system for wireless pager

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.
