E Ink, a pioneer in ePaper technology, has announced the debut of its largest color signage display to date, the 75-inch E Ink Kaleido™ 3 Outdoor display—at Integrated Systems Europe (ISE) 2025. The event, will feature the display in the booths of Samsung Electronics (#3F500), LG Electronics (#3K100), DynaScan (#3C700), and Agile Display Solutions (#4A500).
Designed for the Digital Out-of-Home (DOOH) advertising sector, the 75-inch Kaleido 3 Outdoor display combines dynamic color capabilities with low energy consumption, targeting indoor and outdoor applications. Its print-color ePaper technology supports 4,096 colors and clear text, mimicking the visual impact of traditional printed posters while operating in temperatures from -15°C to 65°C without external heating or cooling.
“As countries prioritize reducing carbon footprints, E Ink’s displays offer sustainable solutions with minimal power use and no light pollution,” said Dr. F.Y. Gan, President of E Ink. “This new display addresses the demand for dynamic signage that aligns with environmental goals.”
Amid energy crises in Europe, where regulations increasingly restrict digital signage operating hours, the Kaleido 3 Outdoor’s low-power design enables operation via solar energy, bypassing grid dependency. This feature allows businesses to comply with sustainability mandates while replacing high-energy LCDs. The display’s instant update functionality further enhances utility over static paper posters.
E Ink’s focus on eco-friendly innovation is reinforced by its PESG (Product, Environment, Society, Governance) framework, which supports net-zero objectives. According to FTSE Russell, 99.9% of E Ink’s revenue qualifies as “green,” while Moody’s Ratings awarded its green loans an SQS2 (“Very Good”) score for alignment with 2023 Green Loan Principles.
Research from Harvard T.H. Chan School of Public Health notes E Ink’s ePaper emits no blue light, reducing eye strain by up to three times compared to LCDs. The technology is also certified by the International Dark-Sky Association for minimizing light pollution. When paired with solar panels, E Ink’s smart bus stop signage achieves 100% renewable energy use, supporting global net-zero targets.
