Abstract

A method for evaluating a lifespan of an organic light emitting display panel includes: aging an organic light emitting display panel, including first light emitting elements for emitting a first color, second light emitting elements for emitting a second color, and third light emitting elements for emitting a third color, during a preset aging period by displaying the first color in a first pattern area of the organic light emitting display panel and displaying a fourth color in a second pattern area of the organic light emitting display panel; measuring luminances of the first pattern area and the second pattern area by displaying the first color in the first pattern area and the second pattern area during a measurement period; and calculating a lifespan of the first light emitting elements based on the measured luminance of the first pattern area and the measured luminance of the second pattern area.
