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. Various embodiments of the invention enable color display devices
with improved image display quality, with both the appearance of jagged
lines and the appearance of banding reduced simultaneously.
