Abstract: The invention provides methods for the production of full-color, subpixellated organic electroluminescent (EL) devices. Substrates used in the methods of the invention for production of EL devices comprise wells wherein the walls of the wells do not require surface treatment prior to deposition of electroluminescent material. Also provided are EL devices produced by the methods described herein.

Abstract: There is provided a process for forming a workpiece comprising a first layer and a second layer, said process comprising (i) forming a patterned first layer having at least one pattern area comprising a first material having a first critical surface tension surrounded by a second layer comprising a second material having a second critical surface tension greater than the first critical surface tension; (ii) depositing a liquid composition comprising a third material in a liquid medium over the pattern area of the first layer and a portion of the second layer; wherein the third material is deposited by a pre-metered coating method. The pattern area in the first layer may be continuous or be composed of discrete deposits of the first material on a substrate. The workpiece so formed is useful in electronic devices including OLEDs.
