"Something that might take more battery than a purely e-ink solution but perhaps be easier to drive and find would be to use display like what was on the original OLPC. It was a color screen that could go down to a 4 bit, unlit mode that looks absolutely gorgeous in any light for a grayscale display. I wonder if that would be any easier to come by but still accomplish a lower battery usage than a regular display."

"The generic name of that technology is “sunlight-readable LCD”, and it’s definitely still available. Also much faster, somewhat cheaper, and more colorful than e-ink. Uses more power, but transflective displays work without backlight, though at a relatively narrow viewing angle. Some of the old Blackberries had them."
