Great topic, and I’ve been digging into the same failure modes while stress-testing prototype panels. The one that trips people up most is current crowding at the driver interface—not the LED material itself. When you’re pushing 240Hz+ into self-emitting micro-LEDs, the TFT backplane’s on-state resistance varies across the array, and pixels near the periphery of each sub-block see elevated IR drop. This manifests as a subtle brightness gradient that only shows up during fast-moving scenes with dark foregrounds, exactly the kind of content esports players care about. The root cause is rarely the LED chip; it
