SmartKem Joins Hi-Accµracy Project Developing Active-Matrix Printed Q-LED Displays

The collaborative Hi-Accµracy project brings together eleven of the most innovative and forward-thinking companies in the industry in a bid to establish the next generation of organic and large area electronics (OLAE) – including organic thinfilm transistors (OTFT) and electroluminescent quantum dot light emitting diode (EL-QD-LED) based displays. 

Overseen by an advisory board made up of Sony, Huawei and Polar, the Hi-Accµracy project is targeting the displays market to give Europe the opportunity to make a step-change beyond the technologies currently utilized in the Far-East – creating valuable intellectual property together with new manufacturing and job opportunities. Hi-Accµracy has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No. 862410.

SmartKem’s role will include developing an OTFT back-plane upon which consortium member Fraunhofer IAP will print a QD-LED front-plane. The backplane utilises a compact, two transistor one capacitor (2T1C) circuit. Q-LED materials will be added to the front-plane using high resolution electro-static jet (ESJET) printing. The resulting 300ppi RGB display will showcase the performance of SmartKem’s range of Truflex materials when used in conjunction with micron scale additive patterning processes and low temperature processing conditions. SmartKem believes its technology has the potential to enable the sustainable manufacture of high quality, robust, flexible displays at low cost. SmartKem are also working with consortium member VTT in the project to adapt their OSC inks for compatibility with highly efficient reverse offset printing (ROP) processes.

Dr Simon Ogier, Chief Technology Officer at SmartKem commented “We are pleased to join the Hi-Accµracy project, which will highlight the potential of high resolution printing for making emissive displays driven by solution processed Organic Transistors.”
