Abstract

A display device includes a light source that includes a blue light-emitting diode (LED) configured to generate a blue output light; a nanocrystal material that is disposed between the light source and a liquid crystal module, and a light guide assembly. The nanocrystal material receives the blue output light, converts a first portion of the blue output light to a green light emission, converts a second portion of the blue output light to a red light emission, and transmits a remainder portion of the blue output light. The light guide assembly includes a planar light guide optically coupled to a light-receiving surface of the liquid crystal module and a curved light guide optically coupled to the planar light guide and configured to receive light from the light source and direct the light toward the planar light guide.
