DELO AND ILLUMINANT DUAL LIGHTING DEVICE

摘要

Organic light-emitting diode, OLED, comprising a stack comprising successively and in order: a first electrode (2, 8), a first type of electrode, among anode (2) or cathode (8), transparent, a first transport layer (3, 7) of a first type of charge carrier, among electron or hole, a transmission layer (5), a second transport layer (7, 3) of a second type of carrier, charge, different from the first type of charge carrier, a second electrode (8, 2) of a second type of electrode, different from the first type of electrode, wherein said emission layer (5) is able to emit a a white color, such that the emission (21) through said first electrode (2, 8) is substantially in accordance with an illuminant D65, where said second electrode (8, 2) is transparent, and where the thickness of the second transport layer (7, 3) is set in such a way that the emission (22) through said second Me electrode (8, 2) is substantially in accordance with an illuminant A. The invention further relates to a lighting device comprising at least one such OLED.
