    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.

    Use our free e-paper software to prepare your bitmap image for this display, also you could make the picture on our bitmap conversion website: www.it-iot.cn/English.html
