With electricity prices constantly rising, it's important that you also take into account the ongoing costs to run your television. Search form Search. Home entertainment. Different types of televisions offer different advantages, but also differ in terms of cost.
What size TV should I buy? Energy efficiency of different TVs Screen resolution What is an 'aspect ratio'? Plasmas can also produce richer, more natural colours, due to both light leakage and to a limit on the hues that LCD can reproduce. Plasma pundits will also tell you that some LCD screens have a tendency to blur images, particularly during fast-moving scenes in movies or in sport.
While that was true for older generation LCD screens, newer models have improved significantly — so much so that the differences in performance between LCDs and plasmas in this regard is almost negligible.
While the pixel response time, measured in milliseconds ms , can give you some indication of an LCD's performance with fast-moving scenes, it's not always reliable. Traditionally, the biggest advantage that plasmas have had over their LCD cousins is price, particularly in the large screen end of the market.
Depending on the resolution, plasma is still able to beat most equivalently priced LCD screens. At present, the mainstream plasma size is 50 inches, but sizes of 60 inches and above are becoming more common. At these sizes, plasmas tend to be two thirds or less than the price of the equivalent LCD, due to the high manufacturing cost of LCD panels.
LCDs, on the other hand, generally top out around the inch mark — though there have been some ludicrously expensive inch Sony LCDs available. Apart from becoming increasingly price-competitive, LCD has the edge over plasma in several other key areas. LCDs tend to have a higher native resolution than plasmas of similar size, which means more pixels on the screen.
LCDs also tend to consume less power than plasma screens, with some of the newer "Eco" LCD panels able to use half of the power than equivalent plasmas, with the trade-off being lower brightness. In terms of bulk, LCDs are also generally lighter than similar-sized plasmas, making it easier to move around or wall-mount.
This is because LCDs use plastic in their screen make-up, whereas plasmas tend to use glass. While this may have been true of earlier plasma models — which dropped to half-brightness at 20, hours — many modern plasmas have the same 60,hour lifespan as LCDs. This means that both types of TVs will last for almost seven years if left on 24 hours a day.
Instead of lighting the screen with fluorescent tubes, as is traditional, it uses banks of LED lights. There are two types of LED lighting: direct and edge. They came in different sizes and with different power consumption. Plasma TVs are usually having a less life span of about 20,, hours only compared to the LED TVs as their expected life span is around Plasma TV is the television display where the screen of the TV is illuminated by the use of gas diodes or cells present at the back of the screen.
These gas cells plasma cells are light up when electricity is passed through them. In many cases, the uniformity can vary per sample. So your TV might be fine, but your brother-in-law hates the one he bought of the same model. If you want to count wins and losses from the list above, have at it. The thing is, these items don't have equal weight. That's the point. For one person, absolute light output is absolute, for another, black level is above all else. These two performance aspects are, for now, mutually exclusive.
So don't listen to those who say, "well, its brightest, it's best" or "LCD's black level is terrible, so they blow. Reading through this list I'm positive you've mentally weighted certain factors above others, even if you didn't notice it at first. Go with your gut. If you watch at night, and want the TV to disappear into the background, plasma is probably best. Want to know the best part?
The dirty little secret of the TV world? If you're buying a name-brand TV, its picture quality is going to be really, really good. You are seriously picking from good, gooder, and goodly goodest here. Compared with flat panel TVs from just a few years ago, new HDTVs are thinner, brighter, bigger, better-performing, and cheaper than ever before. So have at it. Your new TV is going to be awesome for years to come.
