Ynvisible’s technology is very simple to drive. This is one of the key differentiators to other e-paper technologies. The GPIOs in most MCUs can drive the displays with a minimal requirement of additional components. Apply a positive voltage across the display segment to turn on and short circuit, or apply a negative voltage to turn off. The voltage should only be applied when the display switches or is being refreshed.
