High-contrast 133 PPI black & white price, promotion and inventory labels. 0.3s partial refresh keeps retail shelves accurate and up to date.
Medical Devices
Reflective, glare-free display with bi-stable image retention — ideal for portable patient monitors, diagnostic tools and low-power medical instruments.
Industrial Applications
SPI-ready, all-in-one SSD1681 driver and on-chip temperature sensor make integration into industrial control panels and HMIs straightforward.
IoT Device Status Displays
Ultra-low 4.5mW operation and 0.0006mW deep sleep extend coin-cell battery life for wireless sensors, smart home devices and remote monitoring.
Each GDEM0189T61 display can replace thousands of paper labels annually. Join 15,000+ businesses reducing paper waste with bi-stable e-paper.
Sustainable Packaging
95% recycled materials with FSC-certified packaging. 100% plastic-free protective materials for EU and North American compliance.
Energy Leadership
4.5mW operating and 0.0006mW deep sleep slash energy use. A single coin cell can power months of updates in wireless ESL deployments.
