I was commenting based on my recollection of this article. Granted it's for AMOLED, so it may not apply to microLED. In this regard, AMOLED displays have a strong disadvantage. If you feed less voltage to the organic diodes, not only do they limit their brightness, but their color also changes, so that there might suddenly be visible differences in the color reproduction. https://www.notebookcheck.net/Analysis-DC-Dimming-vs-PWM-Can-you-dim-AMOLED-displays-without-the-flickering.423121.0.html https://www.notebookcheck.net/Analysis-DC-Dimming-vs-PWM-Can... Based on that article, non-PWM based solutions seem to be very hard to implement for smaller devices anyway. Apple has already unfortunately abandoned PWM flicker free displays on almost all their devices. So I have no reason to believe this will change.

Is there a reason they couldn't just jack up the PWM frequency? Most OLEDs seem to be under 500 Hz[0], which leads me to believe that there's something limiting them from performing any faster. Basic LEDs on the other hand can easily operate at frequencies in the 1-5+ kHz range and can be pushed very far if the entire system is designed well. A display running at 10 kHz might not be noticeable to even the most sensitive people.
