We live in a time when modern technology is assessed not only on its scientific or engineering capabilities, but its ability to perform high powered functions whilst simultaneously taking up as little space as possible. Control rooms, for example, which are in operation 24/7, often have a lack of space available. Traditional rear projection DLP cube technology, which is used in control room video walls, on average has a footprint of up to 1.2-1.5m in depth. LED illuminated DLP rear projection is the most suitable display technology when static graphic data is to be displayed for prolonged periods of time, for example static maps or network diagrams, but some control rooms are too small to accommodate this cube technology and so it cannot be used.
