Display pixel balancing for a multi color discrete level display
First Claim
1. A display having a pixel pattern comprising a multiplicity of pixels with each pixel having a multiplicity of primary colour sub-regions of illumination each of which further comprises a multiplicity of illumination areas, the illumination areas being able to be set to an illuminating state or a non-illuminating state wherein:
- (a) the primary colour sub-regions extend in a first direction substantially from one side of the pixel to the other, but in a second direction substantially normal to the first direction have only a limited extent in the pixel; and
(b) the colour sub-regions are arranged to be able to be illuminated with changing intensity with a centre of illumination which is substantially stable with respect to movement in the first direction and is substantially constrained to movement in the second direction.

Abstract
A pixel display includes a pixel pattern containing multiple pixels each of which having multiple primary color sub-regions of illumination. These sub-regions are arranged such that they extend in a first direction substantially from one side of the pixel to the other, and in a second direction, substantially normal to the first direction, they have only a limited extent in the pixel. These sub-regions include a multiple number of illumination areas and are arranged such that the center of illumination is substantially stable with respect to movement in the first direction and is substantially constrained to movement in the second direction.

7. A method of determining a pixel layout pattern for a discrete level display, the display comprising a multiplicity of pixels, with each pixel including a multiplicity of primary colour sub-regions of illumination and each primary colour sub-region of illumination further comprising a multiplicity of illumination areas with each illumination area setable to an illuminating or a non illuminating state, said method comprising the steps of:
