WHITE ORGANIC LIGHT EMITTING DEVICE

摘要

A white organic light emitting device is provided to improve efficiency and service life with minimizing voltage change by parallel-arranging a pair of luminous units around a common electrode. A white organic light emitting device comprises a pair of independent electrodes, and a common electrode and a pair of white luminous units. The common electrode(102) is arranged between a pair of independent electrodes(101a,101b). A pair of white luminescence units(103a,103b) are arranged to be symmetrically faced around the common electrode. The independent electrode is positioned in both ends of the white organic light emitting device and one among the independent electrodes is formed in upper part of the substrate. A pair of independent electrodes are connected in both sides of a resistor.
