Pupil-sized display achieves unprecedented resolution

Researchers developed a pupil-sized display with unprecedented resolution, potentially revolutionizing virtual reality and other applications. This new display uses "metapixels" made from tungsten oxide, which reflect light differently based on size and arrangement, overcoming limitations of traditional pixels in very small screens. The "retina e-paper" display achieves over 25,000 pixels per inch, offering a resolution comparable to the human eye's photoreceptors.
