A screen that can hold a picture after power is removed sounds like a neat trick. It is also a different way to think about what a display is for.
Stillness is the feature
E Ink describes its display technology as bistable. An image can remain visible after power is removed; the display needs energy to change that image, rather than continuously refresh a still page.
That changes the design brief. Instead of asking how much motion you can put on a screen, you can ask what information would be useful if it simply stayed where you put it.
A little more like paper
The display is reflective. Ambient light bounces off its surface, much like paper, instead of a backlight shining through the display toward your eyes. Some devices add their own lighting, but the underlying display behaves differently from a backlit panel.
Pages, signs, shelf labels, and status displays are interesting places to look for this technology. Information that changes occasionally does not always need a screen built around constant motion.
Keep the whole device in view
A display holding an image without power does not mean an entire device uses no electricity. Its processor, radios, lighting, and other components still have energy needs.
The useful question is not whether E Ink wins every screen contest. It is whether its strengths fit a particular job. Sometimes the most interesting piece of technology is the one content to sit quietly and do one thing well.
E Ink is worth a look whenever the information matters more than the animation.
Don't just take our word for it.
