What are the differences between Plasma, LCD and TFT display screens ?
Some buying decisions become more complicated over time. In the past, if you wanted a large flat-panel display, the choice was easy. For a 40-inch or larger screen, you bought a plasma. For a 30-inch or smaller screen, you bought an LCD. Today, the dividing line isn’t so clear. And with prices falling faster for LCD’s than for plasma displays, we may have some price overlap in the not-so-distant future. All this begs the question: How do these technologies differ? And how are they best suited to specific applications? One of the obvious differences is power. Plasma has a lot higher power consumption than LCD, typically in the region of two-and-a-half to three times. And a lot of that gets translated into heat. Along with the higher utility costs associated with the higher power consumption, there’s the potential for increased levels of noise. Most of the larger plasma displays have fans. If you’re in an airport concourse, it really doesn’t matter, because there’s a lot of ambient noise
