Overview

Waveshare 3.7-Inch E-Paper E-Ink Raw Display

The Waveshare 3.7-Inch E-Paper E-Ink Raw Display is a high-resolution electronic paper display designed for ultra-low-power embedded systems and custom hardware projects. Featuring a 480 × 280 pixel resolution and 4 grayscale levels, this raw E-Ink panel delivers sharp text, clear graphics, and excellent readability under ambient light without requiring a backlight.

Unlike conventional LCDs, E-Paper technology consumes power only when the display content changes, making it ideal for battery-powered devices, IoT products, electronic shelf labels, smart tags, and portable information displays.

This version is supplied as a raw display panel without a driver PCB, making it suitable for engineers, product developers, and advanced makers who want to integrate the panel directly into their own hardware designs.
