Those OLEDs are great looking displays. I will probably use them on any instruments that only see operation for short periods (like during a dive). I'm wondering if they might handle the pressure of being under water better as well?
For long-ish deployments (a year or more) I'd have to setup a switching system to enable/disable them - otherwise that ~20mA would be too much power to have them turn on for every sampling event.
And when the e-paper displays get cheap, I'll try them out too...
