Qualcomm is devoloping a screentechnology, called IMOD, that is inspired by butterflywings. Like E-Ink it won't drain power when a still image is shown but it can show video as well! And color is default. And yes it will be good for the eyes like E-Ink. Very intressting.
It is still being developed but a prototype was shown at Society for Information Displays conferens in San Diego.
