Abstract
A color display comprised of red, green and blue picture elements is described. The picture elements are arranged to provide a substantial improvement in the monochromatic line quality of the display. Individual elements of a particular color are arranged to form the vertices of substantially square patterns within the color display. Within each of the substantially square patterns formed by the elements of a single color (e.g., red), the colors not disposed at the vertices (e.g., blue and green) are disposed along a diagonal of the substantially square pattern. In this manner, a series of substantially square patterns of alternating red, green and blue picture elements sharing common diagonals are arranged to form a complete color display.
