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.

Abstract: An electroluminescent display device includes a substrate having a display area surrounding a through-hole, and a non-display area disposed between the display area and the through-hole, a thin-film transistor disposed on an upper portion of the display area and a light-emitting element connected to the thin-film transistor, a plurality of insulating layers disposed between the substrate and the thin-film transistor, a planarization layer disposed between the thin-film transistor and the light-emitting element, and at least one anti-connection part disposed in the non-display area and including the plurality of insulating layers and the planarization layer, in which the planarization layer and the plurality of insulating layers, which constitute the anti-connection part, and each of the planarization layer and the plurality of insulating layers has an undercut shape in which a bottom surface is narrower than a top surface, so that the light-emitting part of the light-emitting element is disconnected in the through-hole by the anti-connection part, thereby penetration of moisture through the light-emitting part may be inhibited.
