The EU has launched a three-year $4.3 million project to develop efficient hyper-fluorescence TADF OLED emitters. The new project called HyperOLED aims to develop materials and matching device architectures for high-performance, hyper-fluorescence TADF OLED emitters. The project is being coordinated by Merck, with project partners including MicroOLED and the Fraunhofer IOF institute.
It is expected that the new OLED emitters will be made by combining TADF molecular hosts with novel shielded fluorescence emitters, targeting saturated blue emission of very high efficiency at high brightness.
The project aims to integrate multiple blue and white stack unit prototypes, 2 x 2 mm² in size on 30 x 30mm glass substrates, into a high-brightness OLED microdisplay based on MicroOLED’s 0.38″ WVGA backplane. The project will also achieve efficiency gains through molecular alignment to enhance light outcoupling.
The EU launched a project called Phebe in 2015, with the aim of developing and commercialising TADF OLED emitters. Phebe’s three-year project’s consortium includes Novaled, Astron-FIAMM, TU Dresden and others. Both the HyperOLED and Phebe projects have some common partners.
TADF are getting a lot of attention worldwide as it seems to be one of the promising paths towards lower-cost OLED emitters and high-efficiency blue OLED emitters. The latest TADF advances will be reported at SID’s Display Week.
