Abstract
The lifetime of an organic light emitting device display may be increased by initially driving the display at a substantially constant luminance. For example, over an initial period of the display'"'"'s lifetime, the display may be driven at a level that may be below its maximum possible light output. After a given amount of time at a substantially constant output luminance, the luminance may be gradually decreased over a second portion of the lifetime of the display.
