| 1. A color display device, comprising: an array of subpixels of at least four different colors, including at least two relatively
higher luminous color subpixels and at least two relatively lower luminous color subpixels,
wherein the subpixels are arranged into groups forming at least two distinct types of pixels, each pixel type including the
two relatively higher luminous color subpixels and at least one of the two relatively lower luminous color subpixels, and
wherein the pixel types are arranged in a pattern such that the relative locations of the two relatively higher luminous color
subpixels in each pixel is repeated in adjacent pixels, and the relative location of at least one of the two relatively lower
luminance color subpixels is not repeated in at least one adjacent pixel;
wherein alternating rows of pixels in the display comprise a first pixel type wherein the subpixels are positioned in a sequence
of red, green, white and blue rectangles, whose long axes are oriented vertically, and whose long axes are parallel to each
other, said sequence of subpixels in said alternating rows of pixels repeating across the width of the display;
interleaving rows of pixels between the alternating rows in the display comprise a second pixel type wherein the subpixels
are positioned in a sequence of blue, green, white and red rectangles, whose long axes are oriented vertically, and whose
long axes are parallel to each other, said sequence of subpixels in said interleaving rows of pixels repeating across the
width of the display; and
said sequences of subpixels in alternating and interleaving rows repeating across the height of the display.
