If you are looking for a videowall display, one of the first decisions you’ll need to make is what display technology to use. There are many kinds of displays available today, but the two main technologies employed in control room applications are Digital Light Processing, or DLP, and LCD. Choosing the right one for your application means weighing-up the advantages and disadvantages of each in terms of longevity, cost and performance.
DLP displays are a hollow box, or “cube”, containing a projector that rear projects an image onto a built-in high-gain screen. Modern DLP cubes use LED light sources which delivery incredible lifespans. Some Mitsubishi Electric cubes are capable of running continuously for over 11 years with no maintenance required. DLP cubes are the only videowall display technology capable of displaying a static image continuously with no problems. So this means long lifespans, huge reliability and no maintenance costs. But, as you’d expect from a high-end solution, DLP cubes are relatively expensive and they require a relatively large floor area.
LCD displays, on the other hand, are relatively inexpensive and can be installed practically anywhere. Mitsubishi’s clever front mounting system allows displays to be fitted flush to a wall, maximizing available floorspace. LCD videowall displays should not be confused with LCD monitors or TV’s, however! Mitsubishi’s latest LM55P2, for instance, is built to the same exacting standards as its high-end DLP solutions and comes with a truly impressive feature list which is far beyond the capabilities of a standard LCD display. Like a DLP cube videowall, LM55P2 55” LCD’s can be installed together to create displays of any size – they even have built-in processing to enable multi-window displays to be created with no external processor required. The disadvantages of LCD are that it can be damaged if a static image is displayed for too long, and that its working life is very much less than DLP. But in some applications requiring versatility, or where requirements are likely to change within a few years, LCD actually provides a more cost-effective solution.
