ABSTRACT:
An organic electroluminescent device (1) has an organic emitter layer (5) disposed between, on the one side, a common electrode (6) and, on the other side, a first and second electrode (3A, 3B) which are mutually interlaced and independently driveable. When driven by means of, respectively, the first and second electrode (3A, 3B), respectively, a first and second pattern-wise light-emitting surface emerges. Using different light-emitting patterns, optionally in combination with light-absorbing patterns, a group of icons differing in color and/or shape can be displayed selectively using the same part of a display area.
