Abstract: An organic light emitting diode display is discussed. The organic light emitting diode display according to an embodiment a plurality of pixels configured to operate in an image mode for displaying images, and in an electricity generation mode for generating an electric current. Each pixel includes an organic light emitting diode and a pixel driving circuit. The pixel driving circuit electrically separates the corresponding light emitting diode from one or more adjacent organic light emitting diodes in the image mode, and electrically connects the corresponding light emitting diode to the one or more adjacent organic light emitting diodes in the electricity generation mode.
