Patent ID: 8186865

Claim:
A color light guide panel, for differentiating an incident light into multiple color lights, comprising: a substrate, having a plurality of pixel regions; and a color light output structure, disposed in each of the pixel regions, and the color light output structure comprising: a first nano-pattern, scattering the incident light for producing a first color light; a second nano-pattern, scattering the incident light for producing a second color light; and a third nano-pattern, scattering the incident light for producing a third color light, wherein the color light output structure further comprises a fourth nano-pattern, the incident light is scattered by the fourth nano-pattern for producing a fourth color light, and the fourth nano-pattern comprises a plurality of nano particles, wherein a space between the nano particles of the fourth nano-pattern is Dd or a multiple of Dd, wherein Dd is 600 nanometers±30 nanometers, and the color of the fourth color light is yellow.
