Using quantum dots for extending the color gamut of LCD displays

摘要

A light emitting diode system, with an LED junction, energized to emit light, and a lens cap, covering the LED junction device and receiving the light. The lens cap can be formed in a shape to focus the light, for example. The material forming the lens cap has quantum dots mixed in with the supporting material, which can be in multiple colors. The supporting material can also have particles of glass or other crystalline material mixed therein. There can also be an outer casing over the supporting material, and the outer casing can also have glass or other crystalline particles mixed in.
