E Ink has unveiled a major step forward for energy-efficient digital signage with the installation of a 75-inch e-paper display at Taipei Taoyuan Airport in Taiwan. The company says this is the largest E Ink display ever installed in an airport, showing how e-paper technology could play a bigger role in advertising, travel information, and public signage.
The new 75-inch e-paper screen is designed to deliver bright, highly visible content while using far less electricity than conventional digital displays. Unlike traditional LCD or LED signage, e-paper only needs power when the content changes. Once an image, notice, or advertisement is displayed, it can remain visible with virtually no ongoing energy consumption.
This makes the technology especially attractive for airports, transit hubs, shopping centers, and other high-traffic locations where signs often stay unchanged for long periods. For venues looking to cut energy costs and reduce environmental impact, large-format e-paper signage could become a practical alternative to standard digital screens.
The display installed at Taipei Taoyuan Airport uses E Ink’s Kaleido 3 color e-paper technology. This allows the panel to show color content while relying on ambient light for visibility, rather than requiring a constant backlight. As a result, it offers a paper-like viewing experience with strong readability in public spaces.
Although e-paper is best known for static images, the company says this airport display can also support animations and video-style content. That could make it more flexible for advertising campaigns, passenger information, promotional messages, and other digital signage uses where visual movement can help capture attention.
The project is not just a showcase of screen size. It also highlights a complete digital signage platform that combines hardware, software, and advertising management. Dynascan Technology is supporting the hardware side of the installation, while Omni Media is handling software integration and advertising coordination.
E Ink has been working for several years to expand e-paper beyond e-readers and smaller screens. The company previously invested in production capabilities for larger printed displays, opening the door for bigger applications in commercial signage. Earlier demonstrations included large e-paper panels used in bus stop concepts, showing how the technology could support public information systems with reduced energy demand.
The 75-inch airport installation shows that large e-paper displays are moving closer to real-world commercial use. Airports are an ideal testing ground because they need clear, reliable signage throughout the day, often in areas where reducing power consumption can make a meaningful difference.
As businesses and public facilities continue searching for greener display solutions, e-paper signage could become an increasingly important part of the digital advertising landscape. With its low power requirements, strong visibility, and growing color capabilities, E Ink’s latest airport display points to a future where digital signs are not only eye-catching but also more sustainable.
