Researchers hailing from Uppsala University and Gothenburg University in Sweden have put forth a proposal for a cutting-edge anti-glare electronic ink screen. This innovative screen leverages electrically adjustable 'metapixels' that are a mere 560 nanometers in width. As a result, it achieves an extraordinary pixel density exceeding 25,000 PPI, a figure that vastly outstrips the current 4,000 PPI level found in mainstream VR headsets. This significant breakthrough is anticipated to rectify the limitations inherent in electronic ink display technology, particularly in terms of clarity and color reproduction. It paves a promising path for the development of ultra-compact VR headsets and AR glasses that offer retina-level display quality. Moreover, it is poised to spur innovative advancements in applications such as wearable devices.
