Not necessarily. On the Kindle it takes about that long because it uses greyscale mode, which is slow, and also flashes the screen first to reduce ghosting, which doubles the time.
In 1-bit mono mode you can flip a pixel in ~100ms, which is plenty fast enough for text entry, although scrolling might not be good.
Early LCDs had terrible ghosting (anyone remember trying to play Doom on an early mono LCD and the image instantly turning into incomprehensible hash?), but I can't find any references for actual numbers for the pixel flip time. I'd be interested to know how they compare to eink. Does anyone know?
- simcop2387 11y agoNo idea about the actual numbers, but people have gotten ps1 games working on e-ink displays. I'd think that'd indicate it's probably perfectly doable for text editing. https://www.youtube.com/watch?v=9fbD753xE-U https://www.youtube.com/watch?v=9fbD753xE-U
- david-given 11y agoThat's really nice (although it is just playing back a video, is not an emulator). If only the Nook had a powered USB port...
- simcop2387 11y agoYea emulation would take more than the cpu on the nook can do, but it really does show that the screen is capable at least. Might never play Crysis but it should be adequate for a lot of thigns.
