It’s important, says Dixon, to think of the product as a system, not a single monitor or display. A key elements is the integrated mounting system (Easy-Access Mounting System), a custom mounting system provided by Planar that allows for perfect panel to panel alignment, a shallow depth of 4.5 inches, and the capability to put the displays into service mode so an individual display can be accessed without adjusting the display units around it.
Another key feature: traditionally a power supply is located on the back of an LCD monitor along with electronics that accepts the signal from the video source that is driving the display; “We’ve removed those components so they can be put in a convenient remote location,” explains Dixon.
Having the internal components of the displays located away from the array itself offers specific benefits for airports, he says. It allows for an ultra-thin display depth; fans, which are required to cool the components, are also put in a remote location reducing the noise of the monitors; and common points of failure (usually related to the internal components) are also moved away from the LCDs allowing for easier servicing of the system. The benefits ultimately lower the system’s total cost of ownership, says Dixon.
At Huntsville, the video wall system is three displays high by seven wide (21 units total). The units are 46 inch-LCD video displays; content is segmented so that a two by three section of screens on the left side of the array are dedicated for departure information, a three-by-three screen section in the middle of the wall runs advertising and local television, and a two-by-three screen segment on the right displays arrival information.
The system is a single concave array that also utilizes electronics that allow the airport to stretch an image across multiple displays. One of the primary benefits Huntsville saw in the design, says Dixon, was the ability to remote locate each of the display’s internal components; all components are located some 100 feet from the array.
