> I understand that one of the big issues with microLED is huge brightness variation between pixels. Due to some kind of uncontrollable (so far) variations in the manufacturing process, some pixels output 1/10 the light (or less) as others.

I instead understand that this is false. Available MicroLED screens (TVs) are in fact brighter than normal screens.

The issue with MicroLED is instead that they are extremely expensive to produce, as the article points out, due to the required mass transfer. Polychromatic LEDs would simplify this process greatly.

Does that in any way contradict the claim that there are large variations in brightness between microLED pixels on the same screen?

I should have specified that I was talking about microLED microdisplays, as shown in the article. Sounds redundant but there are also large format microLED displays which are manufactured by individually cutting LEDs from a chip and placing them on a different substrate with bigger spacing. This process allows replacing the ones with poor brightness during assembly. For microdisplays, on the other hand, the LEDs are fabricated in place and the not individually moved after. The chip is the display.
