Abstract
An electroluminescent device, and a method of making an electroluminescent device that includes one or more color conversion elements is disclosed. In one embodiment, the method includes forming an electroluminescent element on a substrate, where the electroluminescent element is capable of emitting light in a narrow band. The method further includes selectively thermally transferring a plurality of color conversion elements to the electroluminescent element. In another embodiment, the method includes forming an electroluminescent element on a substrate, where the electroluminescent element is capable of emitting UV light. The method further includes selectively thermally transferring a plurality of color conversion elements to the electroluminescent element.
