4.2 inch e-ink display high rate refresh 400x300 SPI

   
       
   

The 4.2-inch e-ink display GDEY042T81, with a 400x300 resolution and SPI interface, is perfect for low-power devices like those powered by solar or batteries. It supports 3s full-screen updates, 0.42s partial updates, and 1.5s fast updates. Once updated, the display retains the image indefinitely without needing power, making it ideal for applications requiring slow updates or semi-static content. This makes it an excellent choice for shelf tags, smart tags, smart home applications, and industrial instruments.
