World’s Tiniest OLED Pixel (300 nm!) Could Put Full‑HD on a Square Millimeter — and Supercharge AR Glasses
What happened — and why it matters Researchers at JMU report a 300 nm × 300 nm, individually addressable OLED pixel — small enough that a 1920×1080 display could fit on roughly one square millimeter. That density is far beyond today’s commercial micro‑displays and directly targets
