Explore the challenges of driving extreme resolution AR displays with imec's state-of-the-art disruptive technology

Apply

Imec develops disruptive technologies for high resolution AR displays to ultimately shrink an 8k TV down to the size of wearable glasses. Integration of sub-micron RGB pixels, driven by thin-film transistor technologies come with various challenges, in terms of power consumption, transparency, bit depth and viewing angle. The main ambition for this topic is to address these challenges from system, architecture and matrix design perspective.

The thin-film transistor has a charge carrier mobility of about 20 cm2/Vs, and can only carry electrons, meaning that only n-type transistors exist. The transistor dimensions for this disruptive state-of-the-art technology will be scaled to 0.01 – 0.001 µm devices, enabled by the AR display scaling roadmap.

The goal of this PhD is to elaborate novel electronic driving concepts and evaluate both the AR display array and peripheral driving circuits, considering the advantages of scaled thin-film transistor technologies. The PhD student should also investigate new Si driver chips required to address the AR display array. In addition to design, the PhD student will also be responsible for the IC and matrix measurements, comparison of experiments and modelling. Designs will be processed in the imec cleanrooms.

The candidate PhD student has a solid background in electronic engineering and circuit design. The PhD work will take place in the large area electronics (LAE) department in imec. The group counts about 45 people with extensive expertise in thin-film processing and design, and has 15 years of experience. The group has a very strong international reputation in this field, with multiple ISSCC publications and an H-index for the thin-film electronics activity of 50. ​
