The formation and growth of bubbles within dark spots in organic light-emitting diodes comprised of an electroluminescent polymer and a Ca–Ag cathode have been observed and studied. Our studies indicate that electric stress and pinholes are two important parameters affecting the formation of bubbles. More detailed analysis reveals the dependence of bubble area on the pinhole diameter.
