High-ACCuracy printed electronics down to µm size, for Organic Large Area Electronics (OLAE) Thin Film Transistor (TFT) and Display Applications.

Project description

A step towards hybrid quantum-dot–OLED displays

The global market for organic electronics is currently estimated at EUR 28.3 billion. Organic displays are the largest revenue source for the organic electronics market. Displays that combine electroluminescent quantum dots and organic light-emitting diodes (OLED) are an emerging technology with the potential to fundamentally change the competition amongst current display technologies. The EU-funded HI-ACCURACY project will contribute to the development of this new generation of brighter, more efficient displays. It plans to produce front- and backplane structures with feature sizes approaching 1 µm. To do so, it will use cutting-edge low-cost materials and printing inks as well as scalable, cost-effective printing and deposition approaches. The successful implementation of the proposed methods will set the stage for commercialising quantum-dot–OLED displays.


HI-ACCURACY aims to deliver the next generation of large area manufacture of flexible OLAE structures such as organic Thin Film Transistors (OTFTs) and Electroluminescent Quantum Dot Light Emitting Diode (EL-QD-LED) displays, to µm-scale feature size printable onto flexible substrates. This is aimed at the large and exciting printed, flexible and organic electronics global market, estimated at €28.3bn with an annual growth rate of >8% which is mainly dominated by displays.

Hi-Accuracy will display front- and back-plane structures with feature sizes approaching 1 µm using low cost materials that can operate at frequencies of >1MHz. This will be achieved through a unique range of cutting-edge materials and printing inks, in combination with inherently scalable, cost-effective printing and deposition approaches, that have non vacuum or minimal vacuum requirement. Specifically, the electronic materials will include a range of low-temperature curable nano-Ag and nano-Au conductors and p-type organic semiconductors with intrinsic mobility of as well as InP, ZnSe and ZnS Quantum Dot (QD) materials and electroluminescent EL-QD-LED material stacks with multilayer barrier layers that can achieve the required WVTR and oxygen transmission rates.

HI-ACCURACY is an ambitious project representing a pan-European EU consortium of world leading research centres and cutting-edge SMEs that are looking to develop and commercialise these technologies of European origin. The project is endorsed by three major global electronics companies: Huawei, Sony and Polar (global manufacturers of displays and wearable health monitors) who will sit on the External Expert Advisory Board and steer the project towards commercialisation.

The final project demonstrators produced will be validated at the industrial facilities of one of the SME partners and the subsequent displays being further processed and tested by the end-user partners in their testing facilities (TRL5).
