This is insane. Almost everything done here to make things fast were things that I had assummed that e-ink displays aready did, because they are so slow, I figured their behaviour was the best that could be achieved after trying all these kind of tricks.
It makes me what other things could be much better if they received some attention from someone who cares about it.
For the grayscale, I'm guessing each physical display would need to be individually calibrated? I also wonder whether the calibration is sensitive to environmental factors, i.e. gets out of whack if the display is too hot or too cold.
I don’t know if this particular display is magnetic particles or not, but epaper is not synonymous with eink. Something can be called epaper and still be lcd based. So I feel the video is misleading by declaring epaper is particle based.
Perhaps a stupid question, But I always thought the whole point of e-ink displays was to have non-volatile display, that is, a mostly static display that persists when the power is out. These projects that focus on driving them at high speed, Is there any actual advantage in using e-ink tech at that point?

Great work. I loved the technical innovations.

Or with aging.
There has to be a reason the e-ink industry hasn't done this yet...

Ok I'm confused now. So is this thing considered epaper, eink, both or neither?
Is one a subset of the other? If so which is the superset?
E ink is a trademark name for electrophoretic displays (magnetic particles) by the company also called E ink.
E-paper is an informal category that anyone can use for any display type.
The display in this video/article is also electrophoretic, but not all displays called e-paper are and it’s aggravating. An example: https://kentdisplays.com/products/color-epaper-displays/
Dither and LUTs - my best friends on ESP32 and paper. Great work also!

They claim e-paper doesn't rape your eyes due to it being passive.
Amazing project, thank you! Keep us updated!
Amazing. Now I want my Kindle to use this driver and run stock Android.
