Abstract
A color display includes a first layer of pixels, each of which has an independently controllable light attenuation so as to control the display intensity of each display pixel independently. A second layer of pixels is provided in which the color of each pixel can be independently controlled. Thus, each effective display pixel can be controlled, independently of the other pixels, with respect to its intensity and chrominance.
Claims31
A display comprising a first layer of pixels, each of which has an independently controllable light attenuation, and a second layer of pixels, each of which provides an independently controllable color, wherein each of the pixels of the first layer is optically aligned with a respective group of pixels of the second layer.
A display comprising a first layer of pixels, each of which has an independently controllable variable light attenuation, and a second layer of pixels, each of which provides an independently controllable multi-hue color, wherein the first layer comprises a switchable light scattering material, and
- the first layer of pixels and the second layer of pixels are adapted so as to provide single layer pixelated intensity control and single layer pixelated multi-hue chrominance control, respectively.
A display comprising a first layer of pixels, each of which has an independently controllable light attenuation, and a second layer of pixels, each of which provides an independently controllable color, wherein each of the pixels of the second layer is optically aligned with a respective group of pixels of the first layer.
