Abstract
An apparatus is directed to providing backlighting utilizing luminescent impregnated material. The apparatus includes a radiation source providing a first radiation and a filter layer optically coupled to the radiation source including a luminescent material designed to absorb the first radiation, and emit one or more radiations. The apparatus further includes a light guide optically coupled to the filter layer and designed to receive the emitted radiation and reflect at least a portion of the emitted radiation. The apparatus additionally includes a display layer optically coupled to the light guide and designed to receive the reflected radiation. The system provides means for providing a first radiation, means for absorbing the first radiation, means for emitting one or more radiations based on the absorbed first radiation, means for receiving the emitted radiation, means for reflecting the emitted radiation, and means for receiving the reflected emitted radiation.
