New e-ink displays could reach "retina e-paper" status with pixel densities over 25,000 PPI

Researchers from Uppsala University and the University of Gothenburg have made exciting advancements in e-ink display technology, proposing a new type of anti-glare screen that could achieve pixel densities exceeding 25,000 PPI. This breakthrough is significant as it promises to enhance the clarity and quality of digital displays, making them more comparable to human vision. Such improvements could revolutionize how we interact with screens, leading to better reading experiences and more efficient use of digital devices.
