Organic Light Emitting Diode An organic light emitting diode (OLED), also light emitting polymer (LEP) and organic electro luminescence (OEL), is any light emitting diode (LED) whose emissive electroluminescent layer is composed of a film of organic compounds. The layer usually contains a polymer substance that allows suitable organic compounds to be deposited. They are deposited in rows and columns onto a flat carrier by a simple "printing" process. The resulting matrix of pixels can emit light of different colors.
The device structure of OLED consists of several layers of organic materials sequentially deposited on glass substrate, each layer having a specific purpose that serves to enhance device quality and performance. Back from Organic Light Emitting Diode to OLED Technology
