The largest optically enhanced LCD video wall in Europe has been installed by GDS in Oslo Central Station, the busiest railway station in Norway. The result is impressive; the brand new G-Wall installed in Oslo covers an area of nearly 60m² and is a great improvement on the previous one, which had old fluorescent tubes installed in 1999.

The new video wall is made of 100 pieces of 46in LCD TFT bonded displays, operating as one single unit. The narrow bezel between the screens guarantees seamless view from long distance and fast reading without interruptions. Moreover the new digital information board allows Jernbaneverket (JBV) to adapt the content depending on the situation very easily.

"The performances of the video wall installed in September 2011 in National Theatre railway station in Oslo (25 pieces of 46in LCDs) proved that G-Wall has been a very good choice and that’s why we decided to proceed with GDS as a partner for this challenging installation," said Geir Hagen, engineering manager telecom at JBV.

"Image quality, safety, service, ability of the product are crucial points, but of course long-term support and reliability are factors that we need to take into consideration when choosing a supplier."

JBV asked GDS to deliver the best in class video wall for railways able to give its passengers clear and complete information and to maintain its quality for many years considering the constraints of such a large format. The path to meet these expectations has been challenging but it has been an honour for GDS to work with JBV on this project and we are proud of the result.

On the technical side, the G-Bond lamination process applied to the video wall screens makes the content more contrasted and readable in high-ambient areas. Moreover the bonding technology improves the safety of the system by reinforcing the frontal surface of the glass and by keeping the pieces together in case of accidental breaks.

The mechanical frame and the bracket system have been designed to allow flexible and modular installations, and guarantees easy access for service and maintenance.

The thermal management of the video wall has been designed to overcome the challenges of such a large system and it is able to manage the thermal micro-environment that it creates, as well as avoid railways dust to become a problem with the aging.
