Provided is a PIN type organic light emitting diode that includes At least one of the transport layers includes at least two elementary transport layers and each elementary transport layer of the same transport layer has, in relation to an adjacent elementary transport layer, a decreasing mobility of charge carriers a farther distance from the emission layer, and consequently providing a decreasing conductivity based on a distance of the elementary transport layer from the adjacent electrode, with the elementary transport layers of the same transport layer having the same dopant concentration.

PIN-type organic light emitting diode

An organic light-emitting diode (OLED) on a transparent substrate includes a microcavity formed between a reflecting cathode and semi-reflecting anode. The microcavity includes multiple organic layers with at least one light-emitting layer. The OLED is characterized by a transparent planarization layer between the substrate and an upper metallic layer forming the OLED semitransparent anode. A process for making such an OLED is also described.
