looks like there is still a pcb within the enclosure?
not sure exactly how e-phoretic screens are driven, but I wonder if you could remove the controller entirely? have just a loose eink screen with a zif that you pass around
like this thing is 0.25mm thick https://www.adafruit.com/product/4262#technical-details
The pcb on the card is just a charge pump that the display demands in order to regulate its voltage. If I shipped that off the card and onto the base, I'd need more contacts.
Those flat flex displays are awesome, though way pricier. Then I'd lose the nice stiff pcb board which allows all the contacts on the back to mate. I could go wireless, but then the power delivery needs to charge a capacitor and the delay between button press and display refresh will go to 30 seconds or beyond
