A video wall is also called a data wall. It includes a number of display panels tiled together so as to create one large screen. A data wall is linked to a video-wall processor that functions https://ledwall21.com as the brain of the data wall. The processor enables the user to regulate the data wall using command and input devices such as a keyboard and mouse.
Data walls are a better alternative to a single large screen because they allow users to customize active display areas and are also cheaper than the usual single large screen. Modern video walls with Digital Light Processing (DLP), Light Emitting Diodes (LED), and Liquid Very Display (LCD) technologies are trusted in control rooms and command centers.
Some common features that are expected from modern video walls are: high performance, compatibility with advanced processors, reliability, and low cost of ownership. This article elucidates the types of modern video walls welcomed in command centers and control rooms:
DLP — These comprise backside projection cubes and a video processor/controller. The projection cubes rely on lamps for displaying images. As long as the light is in working condition, the projection cubes continue to perform. Lamps used in modern project cubes have a life of around 9, 000 hours. Backside projector cubes provide a small impact — the smaller the screen size the bottom the depth, and vice versa. The DLP technology is also considered to be reasonable as compared to LCD technology. High definition and thin frames are two of the greatest advantages of DLP video walls.
LED — The LED technology is just like the DLP technology. It includes interlocking backside projection cubes and a video processor. The light sources are the only difference between the LED and DLP technology. LED cubes are relatively more expensive than their DLP counterpart. However, LED lights gives a clearer image and more settings. It is also low on maintenance. For 7/24 applications in command centers and control rooms, the new LED-illuminated DLP technology is becoming a popular choice.
LCD — This display technology makes use of the light-altering ability of liquid very to display images. An LCD includes flat display panels tiled together and linked to a video processor. Backlighting is required for LCD video walls, as liquid very doesn’t produce light by itself. An LCD video wall could either be mounted upon the wall or it could be built-into a free-standing cabinet. LCD panels are available in ultra-thin and ultra-light versions reducing space usage. The only drawback of LCD panels is that they might need to be replaced following a certain period.
These are the most popular video wall systems that are best with the prerequisites of mission-critical operations. The best way to zero in on the best technology for your application would be by seeing a professional audiovisual systems integrator. There are some senior consultants in this industry, and some of them will provide which you free needs analysis.
