  • Patent number: 6909419
    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.

  • Publication number: 20040201807
    Abstract: A particular multi-domain vertical alignment (MVA) liquid crystal display (LCD) can offer a high contrast ratio and a wide symmetrical viewing angle, without rubbing, protrusion surface, or ITO slit geometry. The viewing angle can be further enlarged by the use of optical compensation films, such as a negative birefringence anisotropic optical film with a vertical optical axis.

  • Patent number: 6552704
    Abstract: 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.

  • Patent number: 4968120
    Abstract: A liquid crystal display device is described which includes two transparent sheets separated by a given distance, with liquid crystal material being disposed therebetween. Adjacent one transparent sheet is a stack of at least three pleochroic polarizers which act to separately polarize each incoming primary color wavelength. A second stack of at least three pleochroic polarizers are adjacent the second transparent sheet and are oriented to select the primary color polarizations exiting from the liquid crystal structure.
