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...)
- 2rsf 7y agoThe backlight is what probably consumes most of the power, AFAIK color displays wouldn't properly work otherwise
- BlueTemplar 7y agoTransflective LCDs only require a backlight in lo light conditions. They have color versions as well (Game Boy Color, Pebble Time...)
