Another MicroLED wall is landing at CEDIA, and this one is at least chasing the right problem. Just Video Walls calls the platform Absolute Black, and instead of leading with resolution or brightness it leads with the surface itself: an ultra-dark phosphor face with emitters that take up roughly a tenth of the visible area of a more conventional design. Less shiny LED area facing the room means less ambient light bouncing back at you, which is the actual reason most LED walls look washed out with a lamp on. They also quote about 99% DCI-P3 and 12-bit source processing, and say the driving scheme keeps scan artifacts out of dark scenes down to 0.001 nits.
The number I keep tripping over is the uniformity claim. They say base color and brightness uniformity is 57% better than their existing technology. Better than their own previous product tells me nothing about how it stacks up against anyone else, and cabinet to cabinet matching is exactly where these walls fall apart in real rooms. I have stood in front of enough LED installs where one panel in the upper left runs a hair green, and once you see it you cannot unsee it for the rest of the movie.
No price, no sizes, and no word on how it holds up after a couple of years of thermal cycling, which is the other thing modular walls do badly. Christie is showing up to the same expo with a 15,000 lumen projector, so the comparison is going to get made whether the vendors want it or not. For anyone who has actually lived with a direct view LED wall: did the module matching drift on you over time, or did it stay put?
