Development of High-Efficiency and High-Reliability Organic Light-Emitting Diode Materials and Devices

Background
Organic light-emitting diode (OLED) displays are commonly found in portable devices, monitors, and TVs used in everyday life. They offer superior performance compared to other displays, such as liquid crystal displays, in terms of lower power consumption and higher image quality, including wide color gamut, large contrast, and high still- and moving image resolution.
SEL is at the forefront of extensive R&D on OLED display technologies that provide high electro-optical conversion efficiency, low driving voltage, and long lifetime. One major achievement is the exciplex-triplet energy transfer (ExTET), an essential technology that is now widely used in OLEDs in commercially available smartphones and TVs.

Goal
This project aims at understanding the relationship between the molecular structure of OLED materials and device properties to achieve high-performance OLED devices. The goal is to identify the properties of OLED materials required for creating high-efficiency and high-reliability OLED devices.
