The concept train features ADP's 28.5-inch HiRaso Panel PC, an industrial-grade embedded solution that combines energy-saving display with robust computing capabilities. It delivers clear, dynamic guidance across various applications—from passenger information systems to bicycle and luggage areas, enhancing reliability and creating a seamless travel experience for passengers.

Unlike traditional displays, ADP's HiRaso Display Technology is an innovative e-paper solution that leverages the bistable properties of Cholesteric Liquid Crystal Display (ChLCD) and ambient light reflection to achieve highly efficient energy use. Power is consumed only during image updates; otherwise, the display operates at zero-power for continuous static content—resulting in a significant 90% reduction in power consumption compared to conventional LCD technologies.

The HiRaso Panel PC features a wide operating temperature range of -30 to 85 degrees Celsius, ensuring reliable performance in harsh conditions. Additionally, its compliance with IEC-61373 shock and vibration standards meets the stringent safety requirements of railway transportation. This guarantees consistent image quality and color representation under demanding conditions, including frequent vibration and high temperatures—while supporting a longer lifespan for the reliable and durable delivery of passenger information. This technological advantage enhances the efficiency of multimedia delivery in concept trains, ensures stable operations, and creates an intuitive, convenient, and comfortable experience for passengers—at the same time aligning with the mission of green transportation.

DB is committed to aligning with the EU's climate change policies, with its green transformation strategy focused on improving energy efficiency, reducing carbon emissions, and developing safer, more convenient, and sustainable transportation. Supporting this mission, ADP is propelling DB’s shift toward low-carbon concept trains by providing highly reliable, top-quality display solutions. In line with future trends in electrification, intelligent systems, and autonomous transportation, AUO remains committed to its biaxial transformation strategy. It will continue collaborating with ecosystem partners across various sectors, from Passenger Information Display Solution (PIDS) providers to public transport operators, to accelerate smart transportation innovations and navigate toward a sustainable mobility future.

AUO Display Plus (ADP) has collaborated with S-Bahn Hamburg, a subsidiary of Deutsche Bahn AG (DB), to unveil a new energy-saving concept train. It enhances passenger communication and operational efficiency while contributing to DB’s green transformation initiatives and supporting the vision of smart, sustainable, and net-zero cities.
