That's surprising, since I was always under the impression that E-Ink displays were pretty low-power. Is it the drawing of the new image that requires so much energy in a small instant?
- nine_k 6y agoE-ink is zero power when displaying the picture. But moving all these tiny ink particles around takes a lot of energy. I suspect that low refresh rates are partly due to the problems of power delivery to the pixels via transparent conductors.
- retrac 6y agoE-ink has no draw when static, but changing from white to black or back involves a physical state change that takes quite a lot of energy. Many eink readers rate their battery life in number of full screen refreshes.
