摘要： A device for displaying images positions a luminescent material between a light source and a liquid crystal display (LCD). The light source, which comprises one or more nonpolar or semipolar III-nitride based light emitting diodes (LEDs), emits a primary light having a specified polarization direction and comprising one or more first wavelengths. This primary light emitted by the light source is a linearly polarized light that eliminates any need for a polarizer. The luminescent material, which comprises one or more phosphors, is optically pumped by the primary light and emits a secondary light having the polarization direction of the primary light, wherein the secondary light is comprised one or more second wavelengths that are different from the first wavelength. This secondary light emitted by the luminescent material is a colored light that eliminates any need for a color filter. The LCD receives the secondary light and displays one or more images in response thereto.
