Anyone interested in a group buy of some e-Paper displays, or other stuff from Good Display?


I want to buy a couple of their DES (wide temperature range, UV-proof, fast-refresh) e-Paper displays, but the only shipping options are DHL & Fedex, both about US$28 which makes a US$5 display suddenly very expensive.


So I'm looking to put together an order for 2 or 3 people to share the shipping cost. PM me if you want in.


For anyone who wants to know, e-Paper displays are used on Kindle & Kobo e-readers & Pebble watch, and some supermarket shelf labels. They retain their display when powered off, so can make for really low/no power displays (e.g. electronic name badges). They also have very high contrast ratios, much better than LCDs or LEDs, and are easily sunlight-readable. Interesting twists are flexible displays and NFC updatable displays. Downsides are limited colours, and very slow refresh rates (seconds, not ms). The fast-refresh pretty much overcomes that last issue, but only applies to monochrome displays.

Just out of curiosity, what sort of application do you envisage with this? What can we do?

I plan to hook up to a Raspberry Pi and use as a display for monitoring an engine's temperatures & pressures. I already have a couple of black/white/red e-Paper displays from another supplier, which I subsequently found to be unsuitable due to 15+ seconds refresh time (and irritating flashing/flickering while doing that).
