Abstract

Organic light-emitting devices (OLED) are extremely sensitive to moisture and oxygen. Without high-performance hermetic seals, the life of these devices is limited. Bottom-emitter OLEDs are commonly sealed using epoxy and cover glass with large amounts of desiccant. In top-emitter OLEDs the light passes through the cover glass on which the desiccant typically resides. Thus, transparent thin-film encapsulation without any desiccant is most desirable. This paper reports the results of a robust thin-film encapsulation method that utilizes a layer of aluminum oxide deposited by atomic layer deposition (ALD) process as the primary moisture barrier. More than 1000 h in 85 °C and 85% RH testing has been observed without significant device degradation caused by moisture. Data corroborating this method's superiority over other physical deposition methods for OLED encapsulation are also presented.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
