The article is about a CPU, not a display technology - there's a big difference in functionality and fabrication between those two things, so your iPhone screen pixel example doesn't really fit this use case. I think this flexible CPU tech is interesting. If it's possible to build an ADC onto it and monitor flexible sensors, that would open up one kind of possibility, and probably an advantage over chip-on-flex solutions. I'm sure there are many more interesting uses for this. It's impressive that a CPU can be implemented with this tech, but interesting things can be done with far fewer gates.
