Patent ID: 8237642

Claim:
A method for adjusting the intensity values of colored pixels wherein each pixel has a first subpixel, a second subpixel, and a third subpixel, wherein each of the subpixels emits light of a different color and the lifetime of the first subpixel is lower than the lifetimes of the other colored subpixels, comprising: a. for each pixel, receiving intensity values corresponding to the intensity of each color subpixel in each pixel; and b. adjusting by lowering the intensity value of the first subpixel in each pixel when producing saturated colors between green and red, with no-adjustment of the intensity of the first subpixel when producing neutral colors, wherein the subpixel colors are red, green, and blue, the first subpixel is the blue subpixel, the colored pixels are part of an electroluminescent display, and the adjustment is based upon the blue, cyan or magenta color saturation of the pixel, where the color saturation is calculated as a difference between the intensity of the first subpixel and a function of the second subpixel intensity and the third subpixel intensity.
