A method of setting a driving voltage of a display device including the steps of: measuring luminance of the display device; obtaining a color coordinate from the luminance of the display device and determining luminance efficiency with respect to the color coordinate; determining an initial value of the driving voltage with respect to the determined luminance efficiency; and determining an optimal driving voltage of the display device by using the determined initial value of the driving voltage.

Method for setting driving voltage of display device

A method for aging an organic light emitting display includes estimating a lifespan curve of a display panel based on at least one initial aging profile of the display panel, correcting at least one of a target luminance or a target white color coordinates of the display panel such that the estimated lifespan curve corresponds to a target lifespan curve, and setting a lifespan look up table by storing at least one of the correction value of the target luminance or the correction value of the target white color coordinates.
