Generally, for FPDs running 24/7 or20/7, plan for a useful life of about three years. Although FPDscan usually survive beyond three years, the image degradationand imaging quality will likely require that the wall be replacedwithin that time. For cubes and tiles, expect a useful life ofapproximately 6 years or more. These products are designed forhigh reliability, very low maintenance and minimal performancedegradation over time. In considering operational costs, alsonote the power consumption required for the entire videowall display. This can vary greatly from design to design. Forexample, for a medium size video wall using 55" FPDs, thepower consumption and heat dissipation might be over doublethat of the same size wall using 80" cubes.Final Comments…This paper covers, in simplified terms, many of the key factorsfor consideration when selecting the appropriate productand technologies for a video wall display. This informationprovides insight for consideration of any new video walldesign. However, aside from what is covered here, thereare many other design-related factors, requirements orconstraints within the physical environment that can alsohave a big impact on setting directions and decisions forsolution design and product selection. With more knowledgeand understanding by all the people involved with the process,there is a higher probability of success while utilizing the bestsolution available for the given application.Jim Gavloski, CTSDirector, Product ManagementControl Room and Video Wall Display SolutionsChristie ®(Jim Gavloski has been with Christie for over 17 years developing and providing video wall displaysolutions for the global Control Room display market).6
