  • Patent number: 9541794
    Abstract: A display may have a first stage such as a color liquid crystal display stage and a second stage such as a monochromatic liquid crystal display stage that are coupled in tandem so that light from a backlight passes through both stages. The dynamic range of the display may be enhanced by using the second stage to perform local dimming operations. The pixel pitch of the second stage may be greater than the pixel pitch of the first stage to ease alignment tolerances and reduce image processing complexity. The color stage and monochromatic stages may share a polarizer. A color filter in the color stage may have an array of red, green, and blue elements or an array of white, red, green, and blue elements. The color stage may be a fringe field display and the monochrome stage may be an in-plane switching display or a twisted nematic stage.

  • Patent number: 9395577
    Abstract: A backlight assembly and an LCD using the same are provided. The backlight assembly comprises: a light source, a conductive copper layer, a dielectric layer, a metallic printed circuit board and a heat sink. The dielectric layer is attached to one side surface of the metallic printed circuit board. The conductive copper layer is mounted on the dielectric layer. The light source and the heat sink are respectively connected to the conductive copper layer. The light source utilizes the conductive copper layer to conduct electricity and to conduct the heat to the heat sink. The backlight assembly has the heat sink connecting to the light source through the conductive copper layer to shorten the heat dissipating path of the light source and to enhance the heat-dissipating efficiency of the light source. Moreover, for the narrow frame, the heat sink is directly welded to the bent metallic printed circuit board.

  • Patent number: 9310618
    Abstract: Generally, near seamless electronics displays may be employed in cinema and exhibition applications. Laser scanned displays may be enabled such that the display may display three dimensional (“3D”) content. A first method to enable a laser scanned display for 3D content may employ polarization, with or without polarization conversion and another method may employ multiple colors. Additionally, the envelope function that may be employed across the display may be achieved by changing laser power as a beam is scanned on the screen or by changing the dwell time of the laser beam on the pixels. One method of minimizing the effects of seams in the screen may be to reduce the screen resolution near the seams by screen design and/or laser beam dwell time or illumination energy.
