☆ INTRODUCTION
This is a 4.2 inch e-ink display Good Display e-paper screen with 400x300 resolution, SPI interface, and the display is capable to display images with black and white content. It supports 3s full screen update, 0.42s partial screen update, and 1.5s fast update. 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. Your image holds indefinitely without power – put up your image, then shut down the power.
This 4.2 inch e-ink display GDEY042T91 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.
