1. An autostereoscopic display, comprising:
- a pixelated display panel, pixelated display panel comprising an array of single color pixels or an array of sub-pixels of different colors, wherein each group sub-pixels define full color pixels; and
a view forming arrangement, wherein the view forming arrangement is positioned over the display panel,wherein the view forming arrangement is arranged to direct light the light from different pixels or sub-pixels to different spatial locations, thereby enabling different views of a three dimensional scene to be displayed in different spatial locations,wherein the pixels of the display panel form a hexagonal grid, with a maximum internal angle deviation from 120 degrees of 20 degrees or less,wherein the hexagonal grid repeats with translation vectors a and b, and the lengths of the translation vectors a and b have an aspect ratio of the shorter to the longer between 0.66 and 1;

Abstract
An autostereoscopic display comprises a pixelated display panel comprising an array of single color pixels or an array of sub-pixels of different colors and a view forming arrangement comprising an array of lens elements. The pixels form a hexagonal grid, and the lenses also repeat in a hexagonal grid. A vector p is defined which relates to a mapping between the pixel grid and the lens grid. Regions in the two dimensional space for this vector p are identified which give good or poor banding performance, and the better banding performance regions are selected.
