I really hope microLED takes off in the near future. It's basically OLED on steroids, all of its advantages without the risk of screen burn-in. It's just too expensive right now...
What about Hisense with the U8H Class are they using microled(they call it miniled)? this Tv is not that expensive compared with other brands and tbh the image quality in the high-end models are awesome.
MicroLED requires each pixel to be its own light source (same with OLED). MiniLED is marketing for a fairly dense array of backlight zones on an LCD panel.
