The only technology I've heard of that might outperform it is directly-driven nanorods, something Samsung has been experimenting with. These are basically the same thing as "quantum dots", except that instead of small round crystals they are rod shaped. Apparently if they're aligned and excited by an electric field, they glow with a pure colour. This makes them very similar to microLEDs, but potentially much cheaper to manufacture. However, other than some breathless press-releases a few years ago I haven't heard anything happening recently, so it's possible the technology didn't pan out. https://www.channelnews.com.au/new-samsung-lg-premium-display-war-nanorod-qled-tipped-to-be-superior-to-oled/ https://www.channelnews.com.au/new-samsung-lg-premium-displa...
