    Patent number: 9176340
    Abstract: A fiber optic face plate for a display. The display includes a light source, a transparent cover, a diffuser, a brightness enhancement film, and the fiber optic face plate. The fiber optic face plate allows light to be transmitted through the fiber optic face plate based on the light being incident on the fiber optic face plate within an angular region defined by an acceptance cone. The fiber optic face plate absorbs light based on the light being incident on the fiber optic face plate outside the angular region defined by the acceptance cone. A top angular extent of the acceptance cone is positioned at a positive angle from a fiber optic face plate normal and a bottom angular extent of the acceptance cone is positioned at a negative angle from the fiber optic face plate normal.

  • Liquid crystal display and manufacturing method thereof
    Patent number: 9086587
    Abstract: In a liquid crystal display (LCD), a thickness of a passivation layer overlapping signal lines is larger than a thickness of portion of the passivation layer not overlapping signal lines. A spacer may be formed to overlap the signal lines. In an aperture region of the LCD, a thickness of the passivation layer between a common electrode and a pixel electrode is relatively small, and therefore, it may be possible to prevent reduction in the intensity of the electric field between the common electrode and the pixel electrode. Since thickness of the passivation layer may be relatively large, it may be possible to prevent a signal delay of common voltage. A spacer may be formed overlapping signal lines with relatively thick passivation layer. The spacer may have a small height. Cell gap may be adjusted to be uniform, and prevent reduction in aperture ratio of the LCD.
