      For this application, I am hoping reflective LCDs make a comeback or transreflective LCDs. They are much better for typing than e-ink and still easy on the eyes.

      Early apple devices were quite decent out in the sun with the glass screen and transreflective LCDs. I remember my old devices were quite usable even with the not great brightness if I angled it to reflect the sun nicely.

      Waveshare just released a fully reflective monochrome small one with an integrated ESP32 so I am hoping that catches on in the hobbyist communities and people can start building tech decks with bigger screens that aren’t 800€ and a 1Hz refresh rate.

      E-paper is amazing for static text, images (see pimorino screens with E-Ink 6color), labels, and status things, but fast typing and drawing makes them outrageously expensive for hobbyists and even very expensive at large scale like Boox and Remarkable.

        I got the waveshare color e-ink ( https://www.aliexpress.us/item/3256810087715380.html ) to make a custom dashboard display - it is the living embodiment of horrible refresh behavior - no clock on that dashboard. Still, while it’s static it looks really good, you just have to figure out what you want to see on a changeable display that doesn’t change more than a couple of times per hour.

          Oh yeah those E-inks have like a 10 second refresh timem they are meant for static art, images, signage, etc…

          That is why for clocks and dashboards, I think RLCDs like the https://www.waveshare.com/esp32-s3-rlcd-4.2.htm which is an older tech, but nowadays much better reflection to be closer to e-paper, 60Hz and none of the epaper downsides, but much higher power use.

            Yeah, I’ve got mine showing current temperature, forecast and our Google calendar, so it probably refreshes 40-50x per day. The bigger power draw is firing up the WiFi module to check for new information once every 5 minutes. Last battery charge ran about 2 weeks.

      It makes me sad that e-ink is so niche that it will never reach a truly cheap price. Last time I checked it seem to have already achieved its mass production potential. It is so hard to manufacture already, and newer developments just find ways to make fancier screens that are even more expensive and complex to make. The process to make them is already as efficient as it can be.

        Without a decent refresh rate, I don’t see them gaining mainstream appeal. Given that the technology revolves around physically moving particles, I don’t see the refresh rate improving by leaps and bounds anytime soon.
