Space Saving Techniques with a Free-Standing LCD Wall
Large-screen video technologies feature in the list of essential elements that go into the making of a control room. Over the last few years, modern video wall screens such as Digital Light Processing (DLP), Light Emitting Diodes (LED), and Liquid Crystal Display (LCD) have set new benchmarks in displaying information acquired by signal processing systems. This article deals with the various solutions offered by an LCD video wall in a control room or command center. Defining characteristics of LCD video walls
As the name suggests, the LCD technology is a flat panel display technology that harnesses the ability of liquid crystal to modulate light. These video walls are created by placing commercial grade flat panels edge-to-edge with a video processor. Since liquid crystals do not emit light directly, these displays make use of LED backlighting. LCD panels are available in a wide range of sizes. With competition rife in this sector, such panels continue to become lighter and thinner. From the control room standpoint, these LCD panels are an alternative to projection cubes for video walls. Depending on the screen size and mounting method you choose, the depth of your installed displays could range from 9” to 12”. If you have a limited budget, an LCD video wall is recommended. However, it is important to mention here that LCD panels don’t last forever, and will have to be replaced after a few years. Mounting options—the changing scenario
Conventionally, wall-mounted displays have been the norm. When such video walls are to be mounted on a wall, it’s important to ensure that they are impeccably aligned. Before these displays are connected on the wall, your chosen audiovisual systems integrator might ask you to carry out a structural analysis of that particular wall. This is done to ensure that the wall is strong enough to take the added load of the LCD panels. If the building manager or architect does not have confidence in the structural integrity of the wall, wall mounting is an option best avoided.
With space constraints and architectural concerns cropping up, control room furniture manufacturers have responded by offering freestanding video wall cabinets. These self-contained LCD video wall systems are suitable for emergency operations, process control, security monitoring, network monitoring, military operations, and so on.
Here are some desirable attributes demonstrated by a free-standing, self-contained LCD video wall:
• It is custom designed according to the available floor space, ceiling height, and wall space. Although the cabinetry is attached to the wall, the weight of the displays is shifted to the floor.
• The base cabinet rests on the floor and contains the cables and wiring. The cabinet also has enough space for racked ancillary electronics. • Such video wall systems can be designed to include the most advanced screen management tools. They comprise high-definition direct view LCD panels with a video processor. A sound system can be integrated if so desired.
• Installation and training of a free-standing LCD video wall typically takes a day or two.
