Abstract
The disclosed technology relates generally to reflective displays, and more particularly to reflective displays configured to display images with customized and improved viewing parameters. In one aspect, a reflective display comprises a plurality of light-reflective microfacets configured to display an image by reflecting light incident thereon from a light source, wherein light rays reflected by different ones of the microfacets are directed in non-parallel directions.
Claims27
A reflective display comprising:
- a plurality of light-reflective microfacets formed on a major surface thereof and configured to display an image by reflecting light incident thereon from a light source,
- wherein light rays reflected by different ones of the microfacets are directed in non-parallel directions,
- wherein the microfacets are arranged to form a plurality of pixels,
- wherein different ones of the microfacets within at least some of the pixels are configured to reflect light rays to cross unique ones of non-overlapping regions of a viewing window, the viewing window defining an area in a viewing plane parallel to the major surface at a viewing distance therefrom, and
- wherein outside of the viewing window, an intensity of a displayed image falls by more than 30% relative to a peak intensity of the displayed image within the viewing window.

A reflective display comprising:
- a plurality of light-reflective microfacets formed on a major surface thereof and configured to display an image by reflecting light incident thereon from a light source,
- wherein the microfacets have a distribution of microfacet orientations such that an intensity profile of light crossing a viewing window in one or both of a horizontal direction and a vertical direction is substantially non-Gaussian, the viewing window defining an area in a viewing plane parallel to the major surface at a viewing distance therefrom,
- wherein the microfacets are arranged to form a plurality of pixels,
- wherein different ones of the microfacets within at least some of the pixels are configured to reflect light rays to cross unique ones of non-overlapping regions of the viewing window, and
- wherein the viewing window is such that outside of the viewing window, an intensity of a displayed image falls by more than 30% relative to a peak intensity of the displayed image within the viewing window.

A reflective display comprising:
- a major surface having formed thereon a plurality of light-reflective microfacets configured to display an image by reflecting light incident thereon from a light source,
- wherein the microfacets are arranged to form a plurality of pixels,
- wherein different ones of the microfacets within at least some of the pixels are configured to reflect light rays to cross unique ones of non-overlapping regions of a viewing window, the viewing window defining an area in a viewing plane parallel to the major surface at a viewing distance therefrom,
- wherein outside of the viewing window, an intensity of a displayed image falls by more than 30% relative to a peak intensity of the displayed image within the viewing window.
