RE: Regarding vintage LCD screens...
The biggest enemies are heat and humidity, especially the combination. As you say though, watches ran 24x7 for decades with no degradation, and the same is true for photocopier LCDs (well, maybe not 24x7, but ten hours a day) and so many other things. A properly designed controller will give the LCD a symmetrical AC waveform that will not plate either plate, so it should last indefinitely, AFAIK. (Lots of HP-41 links at the bottom of the links page, )
