Organische elektronische Vorrichtungsstrukturen und Herstellungsverfahren

摘要

This invention relates to structures and fabrication methods for organic electronic devices, in particular organic light emitting diodes (OLEDs). A organic electronic device structure (500), the structure comprising: a substrate (506); a base layer (508) supported by said substrate (506) and defining the base of a well (502) for solvent- based deposition of organic electronic material (510, 512); one or more spacer layers (514) formed over said base layer (508); a bank layer (504) formed over said spacer layer (514) to define a side of said well (502); and wherein an edge of said well (502) adjacent said base layer (508) is undercut to define a shelf (516) over said base layer (508), said shelf (516) defining a recess to receive said organic electronic material (510).
