I also forgot to mention that everything is temperature dependent, because ink particles move differently at different temperatures. ;)
OTOH, if you don't mind full refresh (shaking the ink into uniform white by making the whole display black/white/black/white repeatedly a few times) between updates, these displays seem to be quite forgiving, in my limited experience. So it's not all doom and gloom. :)
- MayeulC 6y agoThanks for the insight! It's probably like everything else: make your proof-of-concept (full refresh) work, and refine the rest until you're sufficiently bothered to fix the full-refresh thing :D As a plus, this is likely the most portable way of driving these, voltage levels notwithstanding. I guess you also have "smart" and "dumb" screens, some that include temperature sensors, etc?
- megous 6y agoTemperature sensor can be just a NTC resistor on the cable leading to the display (for example). The program has to select the right "waveforms" for the current temperature. Waveform files have timings for various temperatures.
