INTRODUCTION

 

This is a 4.2 inch color e-ink epd display with 400x300 resolution, SPI interface, and the display is capable to display images with black, white and red content. Your image holds indefinitely without power – put up your image, then shut down the power. Once these e-paper modules are updated they don't require any power and can actually be disconnected entirely and the content will remain on the display indefinitely. 

This 4.2 inch e-ink display GDEH042Z21 is perfect for low power devices powered by solar or batteries, or the products that require slow updates or semi-static content such as digital price tags, electronic shelf labels or signage.

We could provide front light, touch screen and other accessories for you.

Sample code and datasheet are under the Datasheets & Files section.

Use our free e-paper software to prepare your bitmap image for this display.

* This e-ink display module DOES NOT support partial updates
