If we were to go back 10 years ago the only choice that you had to make when buying a new TV was which size and brand, but things are much harder these days. Now you not only have to consider those previous two choices, you now have to choose between a Plasma, LCD or LED TV.
Plasma TVs were the first large flat-panel TVs to come to market, and some of the early versions were beasts, and also required a separate tuner box. They have come a long way since then, with Panasonic being a leader in the Plasma market.
We have known for some time that these new TVs struggle to match black levels of CRT sets, but new Plasmas are now coming close, which is a major factor when choosing a TV. There are two downsides to Plasmas, high-energy consumption and burn-in.
LCDs were next to market, these have now become very popular, but the larger models are much more expensive than their Plasma rivals. The main issue with LCD TVs is the poor black levels, although they have improved over the years. Another bad point is the viewing angle; older models were very poor and could only be watched in a limited field of view.
However, LCD TVs does not suffer with burn images on the screen and have greater resolutions.
Next up with have LED, this is like an offshoot of LCD. Remember that there are two types of LED TV, conventional rear and edge lighting. However, just remember that the latter carries a higher premium. The best part about LED is that they have greater black levels than LCD, and is more on par with Plasma black levels.
For those of you who are concerned about how much energy you use, then you will be interested to know that LED TV has the lowest energy consumption over all the flat panel TVs. Choosing between the three is not that hard for me, i would choose LED; yes they carry a higher premium, but the difference in quality will be worth it.
