First Claim
1. A display device, comprising:
- 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, the nanocrystal material configured to;
receive the blue output light,convert a first portion of the blue output light to a green light emission,convert a second portion of the blue output light to a red light emission, andtransmit a remainder portion of the blue output light;
a liquid crystal module configured to receive the green light emission, the red light emission, and the remainder portion of the blue output light and generate an image that includes a portion of the green light emission, a portion of the red light emission, and a portion of the remainder portion of the blue output light; and
a light guide assembly, comprising;
a planar light guide optically coupled to a light-receiving surface of the liquid crystal module and configured to;
receive incident light traveling in a first direction, anddirect the incident light in a second direction toward the 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 traveling in a third direction from the light source, anddirect the light in the first direction toward the planar light guide.

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.
