Abstract
An organic light emitting diode display and an aging method thereof are presented. The method provides the organic light emitting diode display with improved reliability as a progressive dark defect is removed, and the lifetime and the white balance of the organic light emitting diode display is secured by executing an aging treatment of high luminance using a pixel circuit including an aging circuit for supplying the organic light emitting diode with an aging pulse.
