    LCDs also physically move their pixels to block or emit light.

    I don’t know why we haven’t been able to get a similar effect from an LCD.

      E-ink doesn’t block/emit light. It reflects it. This is why it reads like paper. Instead of having a light blasting at your face, you have light from the front bouncing off of the display into your eyes. This means that your display can use ambient light instead of needing to overpower it.

      Reflective LCD displays actually do exist. You basically have little mirrors behind the pixels because LCDs are transparent and designed to use a backlight. If you’re curious, search RLCD or if you want to see a tablet, the Hisense Q5.
