Abstract:
A color conversion film for a backlight unit that includes an array of light emitting diodes. The color conversion film includes a substantially planar base portion, and a plurality of three-dimensional structures extending from the substantially planar base portion. Each of the three-dimensional structures has at least one sloped surface with a base angle of about 55°-75° relative to the substantially planar base portion. The color conversion film includes a material having a refractive index of about 1.5-1.7.
