Scale matters a lot. e-ink form factors that are used in consumer products have gotten much cheaper.
The smaller 2-3 inch ones (like what some stores use for their pricetags) are only a few dollars. You can find tablet sized displays for ~50 dollars. I eink is often the best choice, especially if you care about power consumption (like a hobbyist project on batteries) and a less obnoxious aesthetic (backlights in dark rooms are annoying).
- 0x53 6y agoI've thought about making an eink calendar before, but since the cost is so high I wondered if it would be cheaper just buy 31 2 inch screens and somehow connect them.

Since our software allows tiling we've built some test large scale composite screens out of our 6" and 9" devices - I think maximum was around 25-50 screens combined in a big virtual surface, with resolution over 10k x 10k pixels. So sure, it can be done, but is a pain to setup and run.
