I don’t know if this is it, but I have a hunch that we’ll solve that pesky issue of a display using so much power sooner or later.

The innovation, based on the technology that is used for rewritable DVDs, uses electrical pulses to create vivid, hi-tech displays that require no power and can be viewed clearly, even in direct sunlight.
 
Already 'solved', pebble time uses an lcd that draws no power in an refresh only state.
 
Now if they can make one that works in daylight lol

The Pebble Time LCD looks better in daylight than it does with internal lighting.

Transflective LCDs have been around for a while. An earlier version of it was used in the first Game Boy Advance.
 
Sounds like they finally perfected color e-ink
