Then came the information revolution and it became necessary for many entities to make use of these devices for many different purposes. Managing, monitoring and regulating complex processes like train routes and timetables, traffic conditions and many other processes started to make use of this technology to display important data and images required to make fast decisions.

Its size can be understood to be proportional to its depth and it is usually considered to be a suitable video wall solution for small control rooms and operation centers owing to its small footprint. The technology is dependent upon lamps to manage the display which need to be replaced from time to time, generally after a period of 9000 hours. The projection cubes can either be wall mounted or installed in a custom cabinet that will rest upon the floor.
DLP with LED illumination
This technology is almost identical to the traditional DLP system with the one difference of using LED technology in place of bulbs. The good part about this technology is the ease of maintenance. The LED light source doesn’t require replacements as frequently as traditional bulbs and can in fact last up to over 60000 hours. This video wall solution will seem to be more expensive initially but when you factor in the maintenance cost, they are a much better deal.
These video wall solutions consists of flat LCD panels that come together to form a matrix. The bezels are thinner and lighter; the system can be mounted directly to the wall or installed in a custom cabinet. They are more ergonomic, have a smaller footprint and are becoming more and more affordable. Maintenance can be an issue but their effectiveness is enough to garner popularity among the masses.
