Sleeping vs disconnecting Waveshare screen
I'm trying to make a pico-powered ebook reader, and I'm a little alarmed by this warning from Waveshare:
>Note that the screen cannot be powered on for a long time. When the screen is not refreshed, please set the screen to sleep mode or power off it. Otherwise, the screen will remain in a high voltage state for a long time, which will damage the e-Paper and cannot be repaired!
Currently, the pico displays a page and then goes dormant until a page-turn button is pressed again, but if I sleep the eink screen while the pico is dormant and then try to use partial refresh again after re-initializing, it causes horrendous ghosting, bad enough to make the screen entirely unreadable, so currently the screen is never being powered off or slept.
On the other hand, if I entirely disconnect the power line of the screen while the pico is dormant and then reconnect when it wakes, there seem to be no ill effects and partial refresh works just fine. Is there any reason why I shouldn't do this?
