Haven't they been on sale in Asia for a few years now as billboards ?

While LCDs still consume power just to display a picture, it can go very low : see how watches can run for a decade on a single tiny battery ! (I'm not even sure that e-ink would necessarily be an improvement there, considering that you'll want a watch to refresh a part of the screen at least once a minute...)

The backlight is what probably consumes most of the power, AFAIK color displays wouldn't properly work otherwise

Transflective LCDs only require a backlight in lo light conditions. They have color versions as well (Game Boy Color, Pebble Time...)
