InkCase+ is a stand-alone 3.5-inch e-ink screen that can either be inserted into a dedicated smartphone case or used as an auxiliary second screen. The design will also let consumers infinitely personalize their phone case with images and allow notifications to be pushed to the low power e-ink screen. This means that when users want to check their notifications or even read a book, there’s no need to power on the main screen as the InkCase+ is always on.
