Has anyone solved the e-paper ghosting issue? Do you just have to set a complete screen re-render every few seconds or something? Fwiw, there are 13-inch eInk displays for ~$140 (https://www.waveshare.com/13.3inch-e-paper-hat-b.htm?sku=27236 https://www.waveshare.com/13.3inch-e-paper-hat-b.htm?sku=272...) which you can pair with a Raspberry Pi (~$40) or ESP32 (~$15) and battery (~$10). Smaller displays are cheaper if you don't need all that real estate. You can then use AI vibe coding and open source projects to throw together your own apps
