Abstract
A method for selecting two different light-emitting materials for use in an OLED device, each of which produces different color light, which combine to produce white light. Each light emitting material has its own point on a chromaticity diagram, and the light-emitting materials are selected such that, when a line is drawn between the first point and the second point, it passes through a desired white area defined on a chromaticity diagram.
