Abstract

A display comprises a plurality of adjacent pixels wherein each pixel comprises three subpixels arranged in a triangular pattern, each having a hexagonal shape and substantially contiguous adjacent boundaries. This pattern allows predetermined subpixels to be increased or decreased in relative size without drastically affecting subpixel shape or the contiguous adjacent boundaries.

Claims

1. A display comprising a plurality of adjacent pixels wherein each pixel comprises;

first, second and third subpixels arranged in a triangular configuration wherein each subpixel has a hexagonal shape and the boundaries of adjacent subpixels are substantially contiguous within each pixel and between adjacent pixels and wherein said second subpixel is an equilateral hexagon having a smaller surface area than that of said first and third subpixels and the shape of said first and third subpixels is a non-equilateral hexagon. PG,15

2. A display comprising a plurality of adjacent pixels wherein each pixel comprises;

first, second and third subpixels arranged in a triangular configuration wherein each subpixel has a hexagonal shape and the boundaries of adjacent subpixels are substantially contiguous within each pixel and between adjacent pixels and wherein said second subpixel is an equilateral hexagon having a larger surface area than that of said first and third subpixels and the shape of said first and third subpixels is a non-equilateral hexagon.

3. A display in accordance with claim 2 wherein said first, second and third subpixels are of the primary colors red, green and blue respectively.
