MIT researchers are stacking microLEDs for super dense displays that will significantly improve future ARglasses and VRheadsets.
Recent advances in microLED technology could significantly improve AR glasses and VR headsets in the future, according to some new research from MIT.
Head-mounted displays have, so far, relied on the same type of screens found in smartphones, tablets, and laptops. But these stacked micro-LEDs could challenges the way VR headsets are built in the future — and greatly expand their visuals. The resulting micro-LED display could theoretically have a resolution of 5,000 pixels per inch . That’s about 10 times the pixel density of your smartphone. While this resolution would serve no purpose on a screen held at arm’s length, it should greatly improve the quality of displays that are about an inch from your eye. VR displays can suffer from the screen door effect where the pixel grid pattern is apparent.
The only competing technology that might be able to match the contrast and density is full-color microLED; however, OLED degrades much more rapidly over time.
