The lifetime of organic light-emitting diodes (OLEDs) strongly depends on removing H2O from the passivation atmosphere. Therefore, practical OLEDs require excellent passivation to block invading moisture and desiccant to remove moisture in a metal can or a glass cap. We observed the emitting area in OLEDs passivated by a glass cap. Dark spots in OLEDs passivated without a desiccant and grew more rapidly than those in OLEDs passivated with a desiccant. We speculated that the difference between both samples is caused not only by the imperfection of our passivation, but also occurrence of H2O from the OLED device.
