Abstract: A pixel for an organic light emitting diode (OLED) display and an OLED display are discussed. The pixel includes a driving transistor, a first transistor, a scan transistor, a first emission control transistor, and an initialization control transistor. The driving transistor includes a gate electrode connected to a first node, a drain electrode connected to a second node, and a source electrode connected to a third node. The first transistor is connected between the first node and the second node. The scan transistor is connected between the third node and a data line. The first emission control transistor is connected between the second node and an anode electrode of an organic light emitting diode. The initialization control transistor is connected between an input terminal of an initialization voltage and the anode electrode of the organic light emitting diode.

Abstract: The present disclosure relates to a compensation method of a display device and the display device having a compensation value storage unit, and more particularly, to a method of performing the compensation by changing a compensation density for pixels included in the display device, and the display device having a storage unit for storing a compensation value for performing the method. According to the present disclosure, the compensation method is provided that includes dividing a display panel into a foveated area and a non-foveated area; performing high-density compensation for a plurality of pixels in the foveated area; and performing low-density compensation for a plurality of pixels in the non-foveated area.
