Abstract
The design of a single pixel in a discrete level display is replicated a large number of times, often over a million times. The design of the pixel arrangement has substantial consequences in the quality of any image reproduced utilizing the pixel arrangement. In reducing unwanted artifacts, many factors must be considered. The present invention discloses a superior form of pixel arrangement for a discrete level display having optically balanced properties in addition to an intermingling of illumination areas at higher intensities and an irregular format of illumination.
