COLOR 4.2 INCH E-PAPER
Red, UC8276, 400x300 Resolution, Paper-Like Displaying, Low Power
 |
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 could provide front light, touch screen and other accessories for you.
You can refer to the following link for the procedures and instructions of automatic e-paper display bitmap conversion: ImageToEpd. Also you could use our free e-paper software to prepare your bitmap image for this display, or make the picture on our bitmap conversion website: Image to Array
* This e-ink display module DOES NOT support partial updates
