JR East Launched World's First OPV-Integrated Advertising Display

From January 21 to 23, at the 2026 SC Business Expo in Yokohama, JR East i‑STATIONS – a subsidiary of JR East, Japan’s largest passenger railway operator – unveiled an advertising display powered by ChasingLight’s OPV (organic photovoltaic) technology. The product successfully demonstrated autonomous energy harvesting under low ambient light, attracting significant attention across industries.

It is the first OPV‑powered advertising screen, designed specifically for indoor and outdoor information media. Its core breakthrough is self‑powering by ambient light – with no external power source – achieving a truly "battery‑free, plug‑free" operation. OPV module is ultra‑thin and lightweight. he non‑toxic nature of OPV materials ensures a high level of user safety.

JR East i‑STATIONS, a subsidiary of the JR East Group, provides display solutions for JR and other railway stations, commercial facility signage, and smart device solutions – serving approximately 99% of Japan's railway users. Its parent company, JR East, is Japan’s largest passenger railway operator, with over 7,400 kilometers of rail network in the Kanto and Tohoku regions, and an average daily ridership of 15.61 million.

Driving low‑carbon emissions is a core strategy for the JR East Group, which has established the “Zero Carbon Challenge 2050” long‑term goal, aiming to achieve carbon neutrality by fiscal 2050.  JR East is actively developing its products toward greater environmental sustainability. At the expo, JR East i‑STATIONS showcased a range of digital signage solutions and, for the first time, applied ChasingLight’s OPV low‑light energy harvesting technology to transit media and digital signage.

ChasingLight OPV module integrated into the display operates stably under low‑light conditions, delivering continuous self‑powering.
