Abstract
An organic light emitting device capable of emitting different colors and including a first layer of emissive material designed to emit light of a first color and a second layer of emissive material designed to emit light of a second color. The device is activated to emit light of the first or second colors by causing different current densities to flow through the device such that the emitting zone is positioned in the first light emitting layer, thereby emitting light of a first color, or in the second light emitting layer, thereby emitting light of the second color.
