Abstract
An OLED display device for displaying a color image includes an array of different colored independently controllable light emitting elements arranged in repeated patterns, a number of light emitting elements of at least one color in each pattern being different than a number of light emitting elements of a different color and the different number of light emitting elements of the different colors being a function of a relative human visual frequency response to the colors, and a relative size of light emitting elements of different colors being a function of a lifetime of the light emitting elements, an efficiency of the light emitting elements, and the number of light emitting elements of the different colors in the pattern, wherein at least one of the lifetime, and the efficiency is different for different colors.
