It is normally great that the display holds its image when no power (it greatly reduces power consuption),
but...
I have an application where it seems best for the display to indicate when power is lost, possible by erasing or filling with a pattern.
Is there any way to set the driver IC to erase the display or otherwise indicate loss of power?
Even just erasing or changing a portion of the display (i.e. where normally an OK or connected icon would be displayed).
(We are looking at how to change the user interface to take advantage of the display remaining after power loss, possibly our MCU can display a reason for power loss just as it is loosing power - all TBD).
