Organic Light Emitting Diode Display

摘要

An organic light emitting diode display with improved aperture ratio includes: a substrate; first and second pixels disposed in a first row of the substrate and third and fourth pixels disposed in a second row adjacent to the first row and respectively disposed in the same columns as the first and second pixels; a scan line and a previous scan line applying a scan signal and a previous scan signal, respectively, to the pixel units; a data line and a driving voltage line applying a data signal and a driving voltage, respectively, to the pixel units; and a common initialization voltage line disposed between the first and second pixels and between the third and fourth pixels, commonly connected to the pixel units, and applying an initialization voltage. One common initialization contact hole connected to all pixels units and one initialization voltage line connected to the common initialization contact hole are surrounded by the pixel units.
