Patent ID: 8228358

Claim:
A matrix display system, comprising: an array of pixels each having a pixel substructure and a first pixel pitch along a first direction for displaying an image in response to input signals to the pixels, wherein the pixels have switchable regions adapted to be activated by the input signals, each switchable region having a corresponding color, each of the switchable regions of a same first color being simultaneously switched and electrically coupled in parallel, the switchable regions of said first color having portions spatially distributed within the pixel according to a first spatial pattern with regions that are non-switchable or only switchable for a different color interspersed, and configured to display a grayscale image with a plurality of drive levels, each visible gray level for said first color being displayed according to the same said first spatial pattern for said first color; and angular pixel control means optically located between the array of pixels and a viewer for collecting light from the array of pixels and presenting the light to the viewer, wherein the angular pixel control means limits the range of angular pixel size associated with said first pixel pitch as seen by the viewer, such that said pixel substructure for said first color along said first direction would be substantially invisible to an average human observer.
