Abstract
An organic light emitting diode (OLED) display and a method of compensating for degradation are disclosed. One inventive aspect includes a panel assembly including a plurality of pixels. Luminance measuring units are formed along a perimeter of the panel assembly to measure luminance of light emitted from the pixels. A processing unit compares the measured luminance data so as to detect and also compensate for a degraded pixel.
