But "The Wall" is different. At 146 inches, it's absolutely gigantic. But even more significantly, it's actually going to ship this year. Although the price is still a mystery, The Wall will go on sale this August, making MicroLED the first brand-new display technology to be commercialized in more than a decade. The last was OLED, which debuted on the Sony XEL-1 in 2008 and now dominates the picture quality race.

MicroLED can also power tiny screens. Apple currently uses OLED displays for the iPhone X and Apple Watch, but it's reportedly developing its own in-house MicroLED displays for use in mobile devices, starting with the watch. Details are scarce and it'll likely be years (if ever) before Apple brings it to market, but Cupertino's interest provides further evidence that MicroLED could be big.
