For instance, it’s as much a myth that LCDs cause eyestrain because their backlights shine into your eyes like a flashlight as it is that reflective screens like E Ink’s are easier on the eyes just because they reflect light. “Light is light,” says VCD Sciences display consultant Lou Silverstein, a fellow of the Society for Information Display. “Your eyeball can’t tell whether it’s reflected or transmitted.” LCDs and E Ink look different because of the way E Ink reflects light. Its pigments sit at the surface and scatter light in many directions, just as paper does. LCDs and even other reflective screens direct light only at certain angles, so the look isn’t quite as uniform as paper. Jepsen says her team has employed a number of tricks to improve the angle of reflection on the 3Qi, but because it’s still an LCD, it will never look quite as much like print as E Ink.
