Abstract

A four color repetitive sequence matrix array for flat panel displays is formed by establishing a repetitive sequence with pixels of four different colors arranged in the rows of the matrix. The sequence commences with a different color in each row, thereby establishing a second repetitive sequence in the matrix columns. These row and column sequences establish a pattern of 16 pixels with sets of four rows and four columns that is repetitive throughout the array.

Claims

1. A color matrix array comprising:

a plurality pixels, each being one of four colors;

blue, green, red, or yellow arranged to form a matrix of rows and columns wherein said columns are perpendicular to said rows;

each row in said matrix having a repetitive sequence of said four colors, each row in a set of four rows commencing with a different one of said four colors such that a first group of two contiguous rows in said set of four rows have a first repetitive row sequence of said four colors and a second group of contiguous rows having a second repetitive row sequence of said four colors, thereby establishing repetitive sets of four rows;

said first and second row sequences arranged such that a repetitive set of four columns is established wherein a first group of two contiguous columns have a first repetitive column sequence of said four colors and a second group of two contiguous columns have a second repetitive column sequence of said four colors, said first and second row sequences with said first and second column sequences establishing blocks of four elements in said matrix formed by two rows and two columns wherein each block contains said four colors one in each element.
