ABSTRACT:
A backlight for a liquid crystal display includes a substantially planar waveguide and a plurality of light-emitting diodes positioned adjacent the waveguide. The plurality of light-emitting diodes emits light having a first wavelength range. A reactive element is disposed adjacent the waveguide. The reactive element emits light having a second wavelength range toward the waveguide when the reactive element is excited by light from the plurality of light-emitting diodes.
