Can e-ink address individual pixels like that? Seems like it should be able to, but the demos you see always involve full screen refreshes.

- habosa 14y agoNewer Kindles no longer need full screen refreshes for every frame, however after a few of these "mini-refreshes" a full screen refresh is needed to eliminate accumulated ghosting.
- bitwize 14y agoYes, you can change individual pixels or sub-full-screen regions. But because the pixels are cells of white titanium-dioxide particles suspended in a liquid, simply writing a new pixel value may leave a few particles floating around. To correct this, older Kindles and Nooks used to flash the screen all white and then all black before displaying a new page. Later models only do this every few page turns (I think on my Nook Simple Touch it's 6).
