Abstract
A reflective color pixel includes a first sub-pixel and a second sub-pixel. The first sub-pixel is for generating a first color. A color conversion layer extends through the first sub-pixel and the second sub-pixel and is disposed in a waveguide. The color conversion layer contains a luminescent material, which converts a portion of light incident on the second sub-pixel into light of the first color. The waveguide guides the light of the first color generated by the luminescent material to the first sub-pixel for emission from the first sub-pixel.
Claims15
A reflective color pixel comprising:
- a first sub-pixel and a second sub-pixel, the first sub-pixel for generating a first color;
- and
- a color conversion layer extending through the first sub-pixel and the second sub-pixel, the color conversion layer being disposed in a waveguide and containing a luminescent material, the luminescent material converting a portion of light incident on the second sub-pixel into light of the first color, and the waveguide guiding the light of the first color generated by the luminescent material to the first sub-pixel for emission from the first sub-pixel.
A reflective color pixel comprising:
- a first sub-pixel for emitting a first color;
- a second sub-pixel for emitting a second color;
- a third sub-pixel for emitting a third color;
- a color conversion layer extending through the first, second and third sub-pixels, the color conversion layer containing a luminescent material for generating light of the first color and light of the second color;
- a waveguide in which the color conversion layer is disposed, the waveguide guiding light generated by the luminescent material in one sub-pixel to the other sub-pixels.
A reflective color display comprising:
- a plurality of pixels, each pixel having a first sub-pixel for emitting a first color, a second sub-pixel for emitting a second color, and a third sub-pixel for emitting a third color, a color conversion layer extending through the sub-pixels and containing a luminescent material for generating light of the first and second color, a waveguide containing the color conversion layer configured to guide a portion of light generated by the luminescent material within one sub-pixel to the other sub-pixels.
