Evaluating High Performance Barrier Films – G. Nisato, et. al., International Display Workshop, October 2001:
Abstract: In order to evaluate flexible plastic substrates for OLED applications, a permeation measurement method was developed. Based on the corrosion of reactive metal films and modeling thereof, this method is used to quantify the water permeation rate of substrates provided with high-performance diffusion barriers, including hybrid multi-layers...

Gas Permeation and Lifetime Tests on Polymer OLEDs – P.E. Burrows, et. al., SPIE, 2000:
Abstract: We describe a flexible, transparent plastic substrate for OLED display applications. A flexible, composite thin film barrier is deposited under vacuum onto commercially available polymers, restricting moisture and oxygen permeation rates to undetectable levels using conventional permeation test equipment. The barrier is deposited under vacuum in a process compatible with conventional roll-coating technology. The film is capped with a thin film of transparent conductive oxide yielding an engineered substrate (Barix™) for next generation, rugged, lightweight or flexible OLED displays. Preliminary tests indicate that the substrate is sufficiently impermeable to moisture and oxygen for application to moisture-sensitive display applications, such as organic light emitting displays, and is stable in pure oxygen to 200ºC...

A High Resolution Color Organic Light Emitting Diode Microdisplay Fabrication Method – W. Graupner, et. al., SPIE Proceedings 4207, 2000:
Abstract: We report experimental results on the evaluation of a sealing technique for organic light emitting diodes (OLEDs) used for high-resolution color microdisplay applications. Based on production and processing requirements for active matrix OLEDs (AMOLEDs) on silicon, the sealing process must protect the device against moisture and oxygen, not only during operation and storage but also during production. A conformal polymer/metal(oxide)/polymer/ multilayer technology was selected for this purpose. AMOLED test structures were produced and tested with and without sealing under ambient conditions as well as in water. The applied sealing process was shown to be compatible with all steps of the OLED-based microdisplay production of eMagin Corporation. Our results confirm that encapsulating AMOLEDs with the described process leads to increased stability, both under operation as well as for storage purposes... More |
