In this article, we first introduce the historical evolution of organic light-emitting diodes (OLEDs). Then, the principle of fluorescence or phosphorescence and the phenomenon of thermally activated delayed fluorescence are described. Some illustrations of the device structure and its electroluminescence efficiency are provided. We classify and introduce the first and the second generation light-emitting materials of OLEDs. Finally, recent development of the third generation light-emitting materials of OLEDs is presented.
