Frequently asked
Is e-ink better for your eyes?
In bright conditions, yes — e-ink reflects ambient light like paper, which is easier on the eyes than a glowing backlit screen. In low light, you need a frontlit e-reader, which is less eye-friendly than a well-calibrated OLED at low brightness.
Can e-ink displays show video?
Modern fast-refresh e-ink panels can show slow-motion video at 30fps, but the 'ghosting' effect makes it unpleasant. E-ink is optimised for static content. Colour e-ink (Kaleido) is improving but can't match LCD for video quality.
