In 20 years, I think we'll look back at LCD/OLED monitors like how we currently look back at CRT/pre-CRT monitors, and wonder how on earth we stared at bright configurations of tiny lights for 10+ hours a day.
Transflexive LCDs are, in my opinion, the future: https://en.wikipedia.org/wiki/Transflective_liquid-crystal_d.... I can't wait until phones/watches/laptops start using these. My eyes will be very happy when that day comes.
