High Accμracy Project 
Press Release July 2020   
Hi-Accµracy:  imec, NeuDrive and IAP collaborating to advance ESJET QD-LED fabrication

The H2020 funded, Hi-Accµracy project aims to product printed flexible, hi-resolution displays, which are more sustainable and lower cost to open up exciting, new markets for display technologies.  Printed displays require extraordinary levels of accuracy in the deposition of device features, and project Hi-Accµracy will utilise a variety of deposition methodologies including ESJET printing (Electrostatic Jet Printing).

In order to test the concept of QD-LED fabrication by ESJET printing, imec designed, and NeuDrive fabricated, test substrates in circular and super ellipse shapes with a pixel definition of 338 pixels per inch (ppi) to 3175 ppi, and aperture ratio of 12 % to 75%.  A third partner, IAP, will now develop a repeatable and scalable QD-LED fabrication processes using ESJET printing onto these substrates.
