You’d be surprised. Drawing 1bpp and dithering, some e-readers could hit 20 or 30 Hz on PS1 games. Not ideal - but high-res and responsive. The flickery second-long updates are just fighting ghosting and building up multiple bitplanes.
On the other hand it has basically zero advantages over LCD at that speed. Even low-power applications have been undercut by memory LCDs.
