  • Patent number: 9761647
    Abstract: An organic light emitting display and a method of manufacturing the same. The organic light-emitting display is a transparent display where one can see through the display to view an image on the other side of the display. Each pixel of the display has a first region that includes an organic light emitting diode and a thin film transistor, and a larger second region that is transparent. The second region is made of either transparent layers or ultra-thin layers so that light is not blocked. A second electrode of the display may include magnesium and may be produced by a selective deposition process, so that use of a fine metal mask may be avoided.
