Title: Light-emitting diode display systems and methods with enhanced light intensity

Abstract: Light-emitting diode display systems are provided which have enhanced light intensity. The enhanced intensity is realized with first and second electrodes, a plurality of light-emitting diodes and a reflector. The first and second electrodes respectively form first and second sets of first and second fingers respectively wherein the first and second fingers are arranged in an interdigitated relationship. Each of the light-emitting diodes is coupled between a respective one of the first fingers and a respective one of the second fingers and the reflector is arranged and positioned to reflect light from the light-emitting diodes. A plurality of diodes are thus positioned so that the reflector combines their light into a beam of enhanced intensity.
