Development of high-performance, hyperfluorescence OLEDs for use in display applications and solid state lighting

Objective

The overall goal of the HyperOLED project is to develop materials and matching device architectures for high-performance, hyperfluorescence organic light emitting diodes (OLEDs) for use in display applications and solid state lighting. The innovative OLEDs will be realised by combining thermally activated delayed fluorescence (TADF) molecular hosts with novel shielded fluorescence emitters, targeting saturated blue emission of very high efficiency, especially at high-brightness levels. Further efficiency gains will be achieved through molecular alignment to enhance light outcoupling from the hyperfluorescence OLEDs. Using shielded emitters will enable simpler device structures to be used, keeping drive voltages low to be compatible with low voltage CMOS back plane electronics. This will enable demonstration of the concept’s feasibility for high-brightness, full-colour OLED microdisplays as one application example.

To develop the hyperfluorescence OLEDs, the following scientific and technical objectives will be targeted:

• Objective 1: Develop shielded emitters
• Objective 2: Develop TADF hosts
• Objective 3: Photo-physically characterise the shielded emitters and TADF hosts
• Objective 4: Anisotropic molecular orientation for enhanced performance
• Objective 5: Design and test prototype hyperfluorescence OLEDs
• Objective 6: Fabricate and evaluate demonstration hyperfluorescence microdisplays

To show the project’s overall goal has been achieved, multiple blue and white stack unit prototypes (2 x 2 mm² on 30x30mm glass substrates with ITO) will be integrated into a high-brightness microdisplay demonstrator (based on MICROOLED’s 0.38’’ WVGA CMOS backplane) and tested that demonstrate significant improvements in functionality, performance, manufacturability and reliability.

Programme(s)

Multi-annual funding programmes that define the EU’s priorities for research and innovation.

Topic(s)

Calls for proposals are divided into topics. A topic defines a specific subject or area for which applicants can submit proposals. The description of a topic comprises its specific scope and the expected impact of the funded project.

Funding Scheme

Funding scheme (or “Type of Action”) inside a programme with common features. It specifies: the scope of what is funded; the reimbursement rate; specific evaluation criteria to qualify for funding; and the use of simplified forms of costs like lump sums.
