    Abstract: A method for accelerated life testing of organic devices is provided. The lifetime of each of one or more individual organic emissive devices is measured at a non-heating current density. Based upon the measured lifetimes of the one or more devices, the device lifetime is determined for a selected luminance. An organic emissive panel is also obtained having a second organic stack that consists essentially of the one or more organic layers of the first organic stack. The junction temperature of the organic emissive panel is then determined at a heating current density. Based upon the junction temperature and the device lifetime of the one or more individual organic emissive devices, the expected lifetime of the organic emissive panel is then determined at the heating current density.

    Abstract: Systems and methods for the design and fabrication of OLEDs, including high-performance large-area OLEDs, are provided. Variously described fabrication processes may be used to deposit and pattern bus lines with a smooth profile and a gradual sidewall transition. Such smooth profiles may, for example, reduce the probability of electrical shorting at the bus lines. Accordingly, in certain circumstances, an insulating layer may no longer be considered essential, and may be optionally avoided altogether. In cases where an insulating layer is not used, further enhancements in the emissive area and shelf life of the device may be achieved as well. According to aspects of the invention, bus lines such as those described herein may be deposited, and patterned, using vapor deposition such as vacuum thermal evaporation (VTE) through a shadow mask, and may avoid multiple photolithography steps. Other vapor deposition systems and methods may include, among others, sputter deposition, e-beam evaporation and chemical vapor deposition (CVD). A final profile of the bus line may substantially correspond to the profile as deposited.

    Abstract: A method for accelerated life testing of organic devices, and in particular large area organic emissive devices, is provided. The first method comprises obtaining one or more individual organic emissive devices, each having a first organic stack comprising one or more organic layers. The lifetime of each of the one or more individual organic emissive devices is measured at one or more temperatures at a non-heating current density. Based upon the measured lifetimes at the non-heating current density of the one or more devices, the device lifetime is determined for a selected luminance. An organic emissive panel is also obtained having a second organic stack that consists essentially of the one or more organic layers of the first organic stack. The junction temperature of the organic emissive panel is then determined at a heating current density. Based upon the junction temperature and the device lifetime of the one or more individual organic emissive devices at the selected luminance, the expected lifetime of the organic emissive panel is then determined at the heating current density.
