  • AMLCD backlight angular control using fiberoptic face plate
    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.
