FAQ

Common questions

What kind of images look best on the display?
Keefrash’s E-Ink screen supports four colors: black, white, red, and yellow. Images that are closer to these four tones will produce the best visual results. High-contrast images with clear outlines and distinct color blocks tend to display the most beautifully.
Do I need to charge the case?
No. The case is powered by your phone’s NFC only during refresh. The image stays on the E-Ink screen without any battery.
