Some years ago there was this „paperlike kindle“ that was advertised with: „you can read it in bright daylight!“ and then we never heard about this invention again.
Edit: thanks for your input. I think I understand now.

The technology you heard about is called e-ink. And for the purpose of a handheld computer, it is rubbish. It cannot refresh quickly, and the DPI for color e-ink will never rival what an LCD display can do. It’s a matter of physics.
E-ink works by physically flipping white and black ink particles such that only the ink color desired is visible. This doesn’t cost much electricity and it’s more permanent than running electricity though crystals or shooting blue light though filters to show color. And it’s subtractive color meaning it’s a passive color method, so any light source works. But anytime involving something physical moving around costs time. Achieving even sixty images a second is nearly impossible with this technology.
