The EU launched a new project called HyperOLED with an aim to develop materials and matching device architectures for high-performance, hyperfluorescence TADF OLED emitters. HyperOLED is coordinated by Merck, and the project partners include MicroOLED and the Fraunhofer IOF institute. This three years project received a €4 million grant from the EU.
These OLED emitters will be realized by combining TADF molecular hosts with novel shielded fluorescence emitters, targeting saturated blue emission of very high efficiency at high brightness. The project will also achieve efficiency gains through molecular alignment to enhance light outcoupling.
The project aims to integrate multiple blue and white stack unit prototypes (2 x 2 mm² in size on 30x30mm glass substrates) will be integrated into a high-brightness OLED microdisplay based on MicroOLED's 0.38" WVGA backplane.
In 2015 the EU launched a project called Phebe that aims to develop and commercialize TADF OLED emitters. Phebe's three-year project's consortium includes Novaled, Astron-FIAMM, TU Dresden and others. HyperOLED share some of the partners in the Phebe project.
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 DisplayWeek.
