Abstract

A display panel includes a light guide with a housing that has at least one elliptical shaped surface including a first focal point and a second focal point disposed along a major longitudinal axis. The display panel also has at least one light emitting diode being positioned in proximity to the first focal point and a reflector associated with an inner surface of the housing. The display panel further includes an optical film positioned in proximity to an outlet of the housing. The outlet communicates with the display screen. Light that is emitted from the at least one light emitting diode passes through the first focal point and is reflected to the second focal point. The light from the second focal point is then directed through the optical film so that the light is diffused to the display screen. Method and apparatus for the display panel also include devices for increasing an intensity of one of a first and a second banks of light emitting diodes if an overall intensity of the display is detected below a set threshold, and devices for synchronizing the illumination of banks of light emitting diodes so no two banks of light emitting diodes are illuminated during the same time period. The display avoids current surges and generated magnetic fields associated with illuminating banks during the same time interval.
