jordan Hypothetically, 120hz e-ink would probably still need full refresh pretty frequently since ghosting would likely remain an issue
Also given that the only way we've managed to surpass slow Kindle-like refresh speeds so far is with fast modes that use dithering, dither-free fast modes in general still seems to be out of reach for the tech
Btw, since I mentioned Kindles, I think it would be helpful to document here that the reason why the Kindle Paperwhite causes strain is due to it constantly keeping the backlight on even at the very lowest level of the slider. The backlight actually cannot be disabled.
However, in comparison, the Kindle Oasis (whatever model was latest in early 2022) feels incredible to read — one reason is because the backlight actually can be turned off on this specific model, unlike the Paperwhite.
I also swear that the Oasis screen panel or anti reflective coating just feels much crisper and sharper to my eyes in general compared to the Paperwhite, even when backlight is enabled.
