Electronic paper is a display technology that mimics the printing effect of ink on paper. Its core advantages are its bistable and reflective characteristics, which mean it consumes very little power and relies on ambient light to display content.

In recent years, as LCD/OLED technology has matured and the global demand for energy conservation and environmental protection has increased, electronic paper display technology has attracted more and more attention from players in the display industry.

With the growing interest in electronic paper technology, it became one of the focal points at the recent Touch Taiwan 2025 exhibition, showcasing electronic paper technology solutions and terminal applications.

Electronic paper technology continues to develop towards larger sizes, full color, and foldable designs.

E Ink Technology

As a leading enterprise in the electronic paper industry chain, E Ink Technology showcased its first wide-temperature full-color electronic paper, E Ink Marquee™, which uses a new four-color particle display system for more vibrant colors, specifically designed for outdoor and digital billboard applications.

The product can operate in environments ranging from -20°C to 65°C without a cooling system, with a maximum size of 75 inches and a display update time of 5 to 7 seconds.
