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.
