☆ INTRODUCTION
This is a 4.2 inch color e-ink display e-paper screen 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 GDEQ042Z21 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 provide the E-Ink Adapter Board for you to connect the E-paper Display.
We could provide front light, touch screen and other accessories for you.
