In need of a medium-sized, seven-colour e-paper/e-Ink display for your next project? Look no further! This raw-display 4.01-inch e-Paper e-Ink eInk/ePaper display from Waveshare , might be what you are looking for. Featuring a display resolution of 640x400, this ACeP 7-colour display is capable of displaying white, black, orange, yellow, red, green, and blue with a full refresh time of 15-seconds.

ePaper / eInk displays are designed to replicate the appearance of ink on paper. Unlike regular displays, which loose their image when power is removed, eInk screens are able to hold text and images indefinitely, even without power. ePaper screens are therefore ultra low power, designed to have a wide viewing angle, and additionally have limited reflection under sunlight. The applications are limitless!

This is a raw display panel. An additional driver board is needed to make this display functional.
