Not quite. E-ink is a different technology[0]; this really is a form of LCD [1], albeit one that has somewhat different reflective properties. That said, I've got an OLPC laptop and was stunned at how legible they were in full sunlight---very impressively different from your typical laptop screen. (E-ink is still better; it has much more of a "writing on paper" feel. But it's slower.)

- jessriedel 16y agoWow, thanks, this is the answer I was looking for. So do the colors still look mostly the same in bright sunlight, or does the screen become more B&W?
- object404 16y agoI have one of the OLPC XO-1 units in my hands. When the backlight is on, it's still readable under very bright light such as sunlight and will look like the kindle's black & white. When you turn the backlight to zero, it switches to ultra-lowpower hi-res black & white sunlight readable mode. It's pretty neat and something I hope to see in all future devices.
