Novel OLED structure could lead to 10,000 ppi displays for VR and AR

It is possible to double the efficiency of colour OLED displays based on white-emitting material, and achieve 10,000 pixel-per-inch density, by replacing the rear reflector with a meta-material, according to Stanford University researchers. Generally there are two types of colour OLED display: displays with side-by-side patterns of red, green and blue emissive materials, and those ...

Lower parasitic loss in 200mm RF GaN-on-Si epi wafer

IGaN of Singapore is claiming lower losses from its 200mm RF GaN-on-silicon epi wafers. “Despite the great promise showcased by GaN-on-Si RF electronics, there remain few issues to be resolved,” according to company technologist Dr Karthikeyan S. “One such issue is the presence of parasitic channel formed at III-nitride/silicon interface, which leads to parasitic loss, ...

Imec developing 15 minute Covid test

Imec has started developing a SARS-CoV-2 test. Unlike current approaches (using blood, saliva, or a nasopharyngeal swab), the new test will identify SARS-CoV-2 virus particles in a person’s exhaled breath. The solution promises the accurate identification of a contagious case in less than five minutes. This will make for faster, easier, more comfortable, and larger- ...

Wearables: A boost for flexible solar cells

Luminescent solar concentrators are sheets that collect light at various wavelengths and re-emit it at a wavelength better matched to a solar cell. They can be created in various geometries – for example a flat sheet can be arranged to collect light over its large surface, and then re-emit it from one edge to a ...

Lockheed Martin gets approval for Shetland Space Centre plans

The UK government has approved plans for Lockheed Martin to transfer its small satellite launch operations to Shetland Space Centre. It hopes this will lead to the creation of “hundreds of space jobs” in Scotland. The UK Space Agency (UKSA) believes the company’s plans to move its UK Pathfinder Launch to the Shetland site, at ...
