DOES it show time even above 50°C if you e.g. press a button?
The display shuts off, goes blank and shows the message upon toutching a button.
Since the display is mechanical moving of pigment though tubes on nano level I think it would be a protective measure for the display.
The module will just keep track of time and display again when the temp. omes in operational window again.
I find it very cool and common sense.
It means that the EPD is fitted with a temperature measuring safety device and logic for durability of the display. Neat.
