Abstract
A backlight sufficiently bright to be useful as a backlight for a high definition LCD television panel, or other types of visual display screens is disclosed. An LED wide enough to provide adequate light energy is used. The light energy is directed into a thin substrate panel via a tapered aperture port, and released toward a viewing surface in a uniform manner due to light guide disrupters calculated to optimize the output pattern.
