A LCD video wall comprises several rows and columns of displays that are tiled together to form a single pallet. Some of the more commonly used display technologies are LCD panels and DLP projection cubes. The key differentiators are physical shape and size. The projection cubes are deeper and have lamps that have to be replaced periodically. The latest LCD panels are not only a few inches deep, but they have ultra thin bezels, unlike typical television screens. A LCD video wall is often used in control and monitoring rooms.
Most people might associate LCD video walls with scenes from films depicting space mission control rooms. However, a LCD video wall can be seen in other places such as control rooms, studios, transportation centers, defense establishments, stadiums and large public sites. Such walls are used for displaying graphics, simulations, live footage, or recorded footage. Multiple feeds can be relayed to the entire wall and sized and placed anywhere on the wall. Layouts can be established and assigned a hot key so that the operator can bring up specific layouts simply by pushing a single key.
With rapid advancement in this technology, there are a number of cutting-edge features that are available in a modern LCD video wall. Here's what you can expect from a leading solution provider:

• The LCD panels that are used in video walls feature high definition signal processing that provides unparalleled viewing clarity. This makes for a very powerful monitoring tool that with ease of operation.


• There are certain applications that require an audio system with the video. A sound system can be easily integrated into the entire system as an optional feature.


• To offer enhanced ease of operation, Windows software, coupled with wireless keyboard and mouse control is commonly provided in such panels to control the screen matrix. For highly advanced operations, touch panels are also integrated.


• Since the internet is such a critical source for information, internet and network applications can be displayed on the screens at the same time. It is common to see video walls that display feed from CCTV cameras and other TV sources.


• Since most operations tend to expand as requirements change, LCD walls can be expanded to cover an even larger area in the future.


• In certain places, where the walls of buildings might not be constructed to carry the weight of a large LCD video wall, a LCD cabinet proves to be a smart alternative. Though this cabinetry is attached to the wall, the weight actually rests on the floor. This system is not only expandable, but is also modular and easy to relocate.
