Objectives
Organic light-emitting diode (OLED) display is a strategic emerging industry. Currentdevelopment of this technology is facing two main problems: (1) traditional organicemitters have a wide emission bandwidth and low color purity, which is hard to meet thewide color gamut requirements of ultra-high-definition displays; (2) blue light-emittingmaterials and devices do not exhibit both high efficiency and long operational lifetime,resulting in higher device power consumption and faster degradation. This project isbased on sensitized OLED technology, using thermally activated delayed fluorescence(TADF) materials or phosphorescent materials as sensitizers, and narrow bandwidthfluorescent materials as emitters to achieve OLEDs with narrow bandwidth, longoperational lifetime, and high efficiency. This project will establish and develop newmethods to prepare high-efficiency electro-optical conversion materials, develop newdevice structures with improved electro-optical conversion efficiency, break through thelimitations of high efficiency and long lifespan of full-color OLEDs, particularly blueOLEDs, in order to support the development of organic optoelectronics industry.
