INTRODUCTION
This is a 4.2 inch e-ink display monochrome electronic paper screen with 400x300 resolution, SPI interface, and the electronic paper screen is capable to display images with black and white content. It supports 3s full refresh, 1.5s fast refresh, 0.42s partial refresh. Once these e-ink display modules are updated they don't require any power and can actually be disconnected entirely and the content will remain on the display indefinitely. Your image holds indefinitely without power – put up your image, then shut down the power.
This 4.2 inch e-ink display GDEY042T81 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.
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
We could provide front light, touch screen and other accessories for you.
