Rear-Projection Tiled Digital Media Walls
Reusability
The physical form and system design of rear-projection tiled digital displays makes them easy to disassemble and reassemble to fit in any space or application, thereby prolonging the useful life of the product. This is a major advantage during renovations, tenant turnover or spatial reconfigurations of large venues, such as sports facilities and convention halls. Rear-projection digital display tiles are able to support practically any image resolution, so that the system will not become outdated as requirements for new content, resolutions and applications evolve over time.
Recyclability and Safe Materials
Many rear-projection tiled digital displays include a solid metal housing and removable internal components, which typically total 80 percent recyclable and 90 percent recoverable materials.

For installations in the European Union (EU), many rear-projection tiled digital displays comply with the Restriction of Hazardous Substances (RoHS) directive, and do not include phosphorous, mercury or toxic liquid coolants. RoHS is a directive on the restriction of the use of certain hazardous substances in electrical and electronic equipment. It took effect in July 2006 across the EU, and is required to be enforced in each member country.
LEED Innovation Credit
Rear-projection tiled digital displays are compatible with the goals of LEED-certified buildings. Under the LEED system, products are preferred if they meet the ENERGY STAR standards for energy efficiency. Although projectors are not currently rated by ENERGY STAR, some leading manufacturers of rear-projection tiled digital displays support the development of an ENERGY STAR specification for projection-based products.
Digital display products cannot directly earn LEED points, but they can contribute to the sustainability of architectural projects. Under the “Innovation in Design” section of LEED, there is an opportunity for architects to apply rear-projection tiled digital displays as an educational tool for occupants. This may help to earn an innovation credit.

Client: London Stock Exchange Since the atrium was an odd shape, flexibility of design options was important. “We investigated a number of different technologies that would address the challenging size of the atrium,” said Adeel Saeed, LSE Group’s head of corporate technology services. With light flooding the space right up to the seventh-floor glass roof, Saeed wanted a display that could operate in real-time. Other display options, such as LED, LCD and plasma, were reviewed but deemed unsuitable either because of the initial and ongoing lamp replacement costs or the high lighting levels in the atrium. “We also needed a display that could be viewed up close, without being overbearing with LED dots, and sufficiently reliable to be able to run 24/7/365 days a year if necessary,” Saeed explained. Design Solutions Another 8 x 6 tile video wall on the balcony overlooks the atrium and can display the same content as the main video wall. On the ground level, there is a mosaic of 46 rear-projection tiled digital displays of different depths and height. Outside the atrium, visitors see updates on four columns of rear-projection tiled digital displays in a 4 x 2 array. Results
