Abstract
An apparatus for evaluating a lifetime of a display panel including first pixels disposed in a first display area and second pixels disposed in a second display area, includes: a controller for driving the first pixels with a first grayscale and the second pixels with a second grayscale during an aging period calculating a first current, a second current, and a third current, which are supplied to the display panel; a luminance calculator for calculating a first luminance of the first display area and calculating a second luminance of the second display area; and a corrector for calculating a first correction current and a second correction current. The controller calculates a first efficiency lifetime and a second efficiency lifetime, and evaluates the lifetime of the display panel based on the first efficiency lifetime and the second efficiency lifetime.
