Their last innovation was called Mirasol SMI, which let them change color within one MEMS block (instead of just switching it between color/black), so that they wouldn't need subpixels to create color. They were way ahead of E Ink in these respects. Unfortunately Qualcomm pulled the plug shortly after the SMI announcement. I'm not sure which part Apple actually bought, whether it was just labs or actual IP as well.
apple device with back light toggle would be fantastic. the pulse width modulation used on their current screens makes my vision slightly blurry even after only a few minutes of use.
i didn't realize there was a chance they might own some passively lit screen technology already. you've gotten my hopes up.
