  • Backlight using reversely mounted LEDs
    Publication number: 20060039129
    Abstract: A display is back lit by reflection of light from at least one point source of light, such as an LED. The reflecting surface can be far, near, or a coating on a package containing the point source of light. The point source of light faces rearwardly, i.e. emitting light away from a viewer, obscuring the source without creating an easily perceptible shadow.
