Is Any of This Linked to MicroLED?

No! microLED is an entirely different technology, and yes, this is confusing. MicroLEDs are insanely tiny, smaller than pixels – actually, Samsung is already experimenting with putting three LEDs in each pixel for its prototype displays. This allows for an incredible amount of control, and it’s likely that microLED displays will surpass OLEDs in several ways, including contrast and color.
However, the technology is not ready for the market yet and is currently far too expensive for consumers to afford anyway. But then, the same was once true of OLED and mini-LED, we’ll be seeing a lot more of microLED in the future. And we’ll likely see MicroLED displays in upcoming iPhone models.
