Did I miss something about microLED not working out?
The Apple Watch will be the testing ground, from 2025 on at the earliest. With larger displays, there is the difficulty that yield (absence of defective pixels) is likely to shrink quadratically with the diagonal (for the same DPI), or in other words, cost increases quadratically. That’s why small displays don’t immediately scale to larger sizes. Everyone
wishes for Micro-LED to be the next technology, but it remains to be seen whether it’ll be viable, and for which display sizes. We’ll be lucky to see Micro-LED iPhones this decade. I wouldn’t hold my breath for iPads and MacBooks.
Note also the OLED timeline:
2015 Apple Watch
2017 iPhone
2024 (?) iPad
2027 (?) MacBook
Micro-LED may take as long, just shifted by 10 years.
