The article says:
> “Traditionally, the [e-paper display] controller used a single-state machine to control the entire panel, with only two states: static and updating,” says Modos cofounder Wenting Zhang. “Caster treats each pixel individually rather than as a whole panel, which allows localized control on the pixels.”
So in practice would it ever actually hit 20W unless you're doing something that requires constantly updating the whole screen, like playing a video game or watching a video? Surely updating only a few pixels at a time can't be that power hungry, right?
