Abstract: The present disclosure relates to a lateral-type vacuum deposition apparatus, and a source block and a source assembly for the same. Disclosed are a source block that may simplify a lateral-type vacuum deposition apparatus and a lateral-type vacuum deposition apparatus using the same. The source block has a predetermined shape. In the lateral-type vacuum deposition apparatus, the substrate and the source block may face away each other. Accordingly, the lateral-type vacuum deposition apparatus including the source block is free of a conduit for transferring a vaporized source to a nozzle, thereby simplifying a structure of the apparatus. In particular, the source block may have a visible light transmittance of at least about 10% and may exhibit excellent shape maintenance ability during a lateral-type vacuum deposition process.

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.
