Abstract

A method of making an improved color OLED display device, includes the steps of: identifying a plurality of different OLED materials having differing chromaticity coordinates, luminance stability over time, and luminance efficiency; calculating an estimate of display lifetime for a plurality of combinations of the different OLED materials used to produce a pixel having a white point with a defined chromaticity coordinate and luminance; and selecting the combination having the maximum lifetime.
