Recently, organic light emitting diodes (OLEDs) have been widely used for portable displays used in smart phones and tablets as well as in big screen TVs. In this seminar hosted by the OSA Optical Material Studies Technical Group, Dr. Franky So from North Carolina State University will present the fundamental chemistry and physics of light emission processes in organic molecules. Specifically, Dr. So will discuss the different emitters used in OLEDs: fluorescent emitters, phosphorescent emitters and thermally delayed fluorescent emitters. In addition, Dr. So will present the functions of other functional organic materials used in OLEDs and the different device architectures used for OLEDs. The seminar will conclude with Dr. So presenting the recent progress of OLEDs and discussing their challenges and opportunities.
What You Will Learn/Seminar Objectives:
- Operation of an OLED device
- The function of different layers in an OLED device and the different materials used in layers
- Mechanisms of light emission and outcoupling of light
- The reliability of OLED devices and future improvements
Who Should Attend:
- Scientists, display engineers, and program managers
- The level of webinar is intermediate. The basic concepts will be explained. However a basic knowledge of emission and absorption of molecules will be assumed.
