Drawing Details
Matching Driver Boards
DESPI-C02
E-ink display adapter board, pure hardware interface, no MCU. SPI to 24-pin EPD conversion.
High-contrast 4-grayscale price and promotion tags with 0.3s partial refresh. Bistable display keeps shelves accurate for years on a single battery — zero power to maintain the image.
Smart Home Devices
170° wide viewing angle with no blue light and zero radiation. Ideal for smart home control panels, thermostat displays and room signage where eye comfort matters.
Industrial Instruments
SPI-ready SSD1680 driver with 4-level grayscale for precise data display. Wide operating temperature range and bistable retention suit industrial meters, gauges and HMIs.
Smart Tags & Portable Devices
Ultra-low refresh power (9mW) and 0.003mW standby enable coin-cell operation. Bistable 4-grayscale image stays readable without power — perfect for asset tags and portable status panels.
Each GDEY029T94 label can replace thousands of paper tags annually. E-paper provides a paper-like touch and reading experience, serving as a sustainable alternative to traditional paper.
Sustainable Packaging
95% of this device's packaging is crafted from wood fiber-based materials sourced responsibly from managed forests or recycled sources. RoHS certified.
Energy Efficiency
9mW refresh and 0.003mW standby slash energy use. A single coin cell can power years of updates in wireless ESL deployments, reducing greenhouse gas emissions.
Why GooDisplay E-Paper Refreshes Faster
Optimized Fast-Refresh FPL
We rigorously select fast-refresh FPL films at the raw material level, laying a solid hardware foundation for high-speed performance without optical trade-offs.
Smart Temp-Controlled Drive
Engineers optimize waveform files for different temperature ranges, ensuring excellent display quality even during rapid refresh cycles in any environment.
Chip-Level Integration
SSD1680 driver IC with integrated DC-DC, SRAM, LUT and VCOM. Optimized waveforms are built into the chip — activate fast refresh mode with a simple code call.
