Plasma vs. LED – What Distinguishes Between Samsung TVs?

by GuestPoster on February 9, 2011

The debate between plasma and TFT fans are probably as old as the technologies themselves, and while I don’t wish to settle it with this article, I aim to provide better understanding on both solutions, and the differences between them. If you’re a tad uncertain on which is what, I suggest you read about Samsung TVs behind the link first, then come back for a quick recap second.

Contrast ratio is so high on plasma TV sets you wouldn’t believe. It’s literally in the millions, which means that the brightest spot is millions of times brighter than the darkest spot on the TV at any given one time. Of course every manufacturer uses their own way of picking the most beneficial way of measuring it, but the idea is this. In comparison TFT panels are shallow and pale, but that’s not to say they’re definitely bad. I’ve seen LED TFT displays that would make your jaw drop and stay like that for minutes before you’d realize you’re watching the screen with an open mouth.

Refresh rate is not so much of an issue lately, TFT panels (and TN-Film at that) have evolved faster than one would care to follow, 120 and 240 hz displays are not very obscure at the time of writing. Sometimes it’s mentioned as a ms (millisecond) value, which is what you divide 1000 by to get the theoretical refresh frequency rate. Plasma panels are not limited by the speed at which transistors switch, because there are none in the actual display panel. The electronic parts that control plasma often limit it to 600 hz, but that’s just as arbitrary as anything, you would probably never notice a thing going from 240 to 600 Hz then back again, unless you perceive flickering more than others, and use the screens in 3D mode, where effective refresh rates are halved.

The dreaded burn-in effect is not the boogieman it once used to be, but it’s still present in plasma screens. Unfortunately, it’s a limitation in how plasma cells in such a screen work; the phosphorus layer loses its visual properties over time. LED screens, which use TFT-LCD display panels plus LEDs to give it the backlight, can also burn in, but that’s more of a theoretical issue than a real, tangible problem.

These are not the real aspects that decide on the matter in most cases, though, as there is a fourth, most overwhelming issue with TFT-LED panels (including Samsung LED TVs), and it’s the size in which they can be economically manufactured. Plasma screens can be made to virtually any size, which is exactly the reason why you’re most likely to find only plasmas in the high 50′s or 60 inches region.
