E-Paper Displays

Bistable, reflective e-paper (e-ink) display modules that consume zero power while displaying an image. Sunlight-readable, paper-like — ideal for IoT labels, smart retail, and signage.

Overview

Paper-Like, Zero-Power Displays

E-paper uses electrophoresis — tiny microcapsules containing charged pigment particles. Once an image is written, it stays indefinitely without power. The result: a display that reads like paper, works in direct sunlight, and sips power only when updating.

Bistable — retains image with zero power consumption
180° viewing angle, fully sunlight-readable (reflective, not emissive)
Available in black/white, black/white/red, and black/white/yellow
Partial refresh support for fast updates without full-screen flash
