We review recent progress in small molecule, stacked organic light emitting devices (SOLEDs) with emphasis on their potential application to lightweight, full-color displays. In a full-color SOLED pixel, the red, green and blue light emitting devices are vertically stacked to provide a simple fabrication process, minimum pixel size, and maximum fill factor. This architecture is uniquely applicable to organic semiconductors due to the lack of lattice matching requirements at the many materials interfaces. We discuss the effects of microcavity effects on the output color of the SOLED, and demonstrate an optimized three color pixel with good color saturation. Various drive schemes for stacked pixel architectures are introduced.
