Q. I want to buy an 40" - 46" HDTV (1080p) for my home to replace my 10 year old 40 " CRT TV. I've seen different types out there: Plasma, LED. LCD. What's the difference and which is considered best (quality-wise). Any references to links that explain the different types of TVs on the market now. I'm just now able to afford getting into 21st century technology and would like some help.
A. Confused about what type of TV to buy? LED LCD Plasma.. How to choose?
After all, there are so many acronyms and buzzwords to wrap your head around, such as 1080p, 120/240Hz, 24p, HDMI and LED backlighting. Huh?
Along with deciding how big a screen you want (which is usually tied to the size of your budget and the dimensions of your room), the next choice should be between LCD.LCD (LED Backlit) or Plasma � and all have their merits. Here, we'll describe each of these formats, and also point out their shortcomings.
LCD
What is it?
lcd tv 120mhzSimilar to your laptop computer's monitor, flat-panel LCD televisions use a liquid crystal display to produce a sharp and bright picture; these crystals are sandwiched between two panes of polarized glass, which are stimulated by an electric current and illuminated by fluorescent tubes housed behind the glass. Some newer LCD TVs, however, use LED-backlighting instead. LEDs, or light-emitting diodes, translate to a better-looking picture (see photo).
Pros
There are a number of advantages to buying a LCD televisions. For one, with more than three-quarters of all televisions embracing this technology, there is a lot of choice when it comes to manufacturers, models and sizes (13- to 103-inches, in fact). Competition, of course, breeds more aggressive pricing, too, which is good news for the consumer.
Flat-panel LCD televisions are also very thin, light and energy efficient, and are ideal for rooms with plenty of ambient light, which, for example, comes through large windows as they tend to absorb rather than reflect light (reflected light can obscure your view of the screen).
Cons
Until recently, LCD TVs didn't handle fast motion images as well as plasma TVs, resulting in a somewhat blurred image. Newer LCD TVs, though, have added technologies such as 120Hz frame doubling (or 240Hz frame quadrupling) to smooth out motion. It's still not as good as plasma, but much better than before. Also, LCD TVs used to have problems showing dark blacks (because a light was still on behind the pixel showing black, resulting in a more greyish hue). Many LCD televisions today use local-dimming with LED-backlighting (see next section) for improved contrast ratios (whiter whites and blacker blacks) - but, keep in mind, this is not an issue associated with plasma TVs.

LCD (LED Backlit)
What is it? Not a Different Type of TV
led lcd tv backlighting backlitIt�s tempting to think LEDs belong in a completely separate category beside LCD and plasma TVs, but in reality, an LED television is just a type of LCD TV. The proper term would really be "LED-backlit LCD TV," but that always seems to get truncated to "LED TV" in everyday conversation, perpetuating the confusion.
To understand how LEDs function in an LCD TV, think of an actual liquid-crystal panel as the plastic pegs in a Lite Brite. They hold a translucent image, but without a powerful backlight to punch through and light it up like a signboard, you�re not going to see much. On your old Lite Bright, an inefficient incandescent light did the job, but pretty unevenly. On a typical LCD TV, fluorescent lights provide the backlighting through a special plastic sheet called a light guide that distributes light from a fluorescent tube evenly over the surface of the TV. On an LED-backlit TV, fluorescent tubes are replaced with light-emitting diodes � LEDs � the same technology that probably lights up your digital watch, the buttons on your monitor, and the indicators on your stereo. They can be either situated along the edges of the TV like a fluorescent tube, or arranged directly behind the screen in a grid. But what difference does it make, and why would anyone spend so much money on it?
The Benefit of LEDs
The most obvious reason LEDs have fallen into favor in LCD TVs: they�re simply more efficient. Although fluorescent lights do a decent job converting electricity to light in the big scale of things, LEDs perform even better. Typically, manufacturers claim an efficiency improvement of up to 30 percent over fluorescent-based sets, which can add up significantly over the lifetime of a TV, especially on larger screens that use more juice to begin with.
LEDs are also much smaller than tubes, even after accounting for the number of them needed to light an entire TV. That means LED-backlit televisions can be manufactured significantly thinner than their tube cousins. For instance, most of the ultra-thin televisions that measured under an inch thick at CES used LED backlights, because they add very little depth to the profile. Though commercial variants aren�t quite as dramatically thin as these prototypes, they�re significantly skinnier than their fluorescent-backlit counterparts, making them some of the most chic and living-room-friendly HDTVs out there.
For home theater enthusiasts, LEDs only matter for one reason: image quality. Because fluorescent tubes mu

Plasma or HDTV which saves energy? Which is the best to buy?
Q. I want to buy a flat screen tv. But I want one that's a energy saver, and one that will last longer than 2yrs. w/o needing repairs.
A. Plasma TV / LCD TV / LED TV ( LCD-LED BACK-LIGHT ) all are HDTV. only difference in HD . full HD 1080 P or HD 720P.
Plasma TV available only 42 inc and above screen. prefect in total pictures quality suited for moving image / sports fast action movies with out so call " motion blur ".
OLD Plasma TV before 2007 is " junk ". very high power consumption over heat . easy burn in. life time not more than 40,000 hours.
Panasonic New Plasma totally " LIVE '. with out over heat. burn in is not an issue any more even long hours still image / play games.
all new Panasonic Plasma from 2008 models are ENERGY STAR QUALIFIED , 60,000 LIFE TIME .
some 2009 new models is super low power consumptions . compare to same screen size LCD TV , no difference in electric use. life time is up to 100,000 hours.better than LCD/LED TV.
if you looking for big screen , Panasonic New Plasma is PREFECT in total pictures quality and PRICES too.

LCD TV come with full screen size from 1 inc to 108 inc. use 40 % less Power consumption than Plasma . such issue is over , New Panasonic Plasma power consumption W , is about LCD TV ( compare to same screen size ).
due to Response time . there must be so call motion blur, even hi end LCD TV try to use 120HZ / 240 HZ high refresh rate to " cover ' the motion blur. but really not that good .
if you like fast action sports movies, 120 HZ with 4 ms Response time is an MUST. but that only available to HI END models.REMEMBER . none of any LCD TV reach Plasma TV total pictures quality.
^^
LED TV ( LCD display use LED as back-light )
LED TV is RE-FINE of LCD TV. those LCD unable to performs well. like dark colour / black colour. LED TV just do it much better . LED TV able to cove much better in motion blur. due to lower Response time 2ms g to g standard .
LED TV use 40 % less ENERGY than LCD TV. compare to Panasonic Plasma is about 30-40 % less too. compare to OLD Plasma ( before 2007 models ) is 90 % lower !
LED TV total pictures quality is very close to Plasma. in general, Mose of human EYE will not get the difference between LED TV/ PLasma TV.
beware of some SMART consumer , there either do not compare or watch any LED TV before or there do not want to paid such high prices for LED TV. some once will tell you " no difference in pictures quality , just use difference back-light. is all the same .is LCD TV with LED back light . no big deal. " that totally not true. is totally some new technologies , the " back light " change and improve many areas. is make great difference. and is very easy for our EYE to noticeable the great difference between LED/LCD TV. jude by you own EYE.
HD 720P VS FULL HD 1080P.
technically , our eye will not getting the difference from an screen size below 40 inc. and the only source provide 1080P is via blue-ray. free view digital channel / Box cable TV / DVD all are 720P.
but TV maker always take LCD TV 720P models as STANDARD.
1080P models as mid HI END models . any 1080P models always much better in pictures quality than 720P models from any in-put source, need not via blue-ray. you eye able to notice the quality.
MAKER QUALITY.
International brand always in quality and reliable , WORTH to paid more.
Local in house brand / buyer brand is cheap, subject to quality and reliable .
an International brand HD 720P models MAY better than house brand 1080P in pictures quality.
Back to you Question > if the above answerer too technically. forget about it.
make it simple .
big screen . Panasonic Plasma PREFECT in PRICES and QUALITY. is LONG LIFE.
LED TV is lower power consumption. great pictures quality . but cost more.
LED TV > Sony and Sharp are new vision of LED technologies .
Samsung Pioneer in LED TV. but is very first LED technologies in use , need to improve.
all LED TV is 1080P 120 HZ or even 240 HZ.
LCD TV , if you need quality also less motion blur , go for hi end FULL HD 1080 P / 120 HZ models.
Samsung / LG / Sony / Panasonic / Sharp / Toshiba LCD equally quality in SAME RANGE PRODUCT. usually the above brand 90 % able to use for 5 years with out any problems.
screen size 42 inc and below , Panasonic is SUPER RELIABLE . 97 % of Panasonic 22- 42 inc able to use for 8 + years with out any repair.
never TOUCH any Local / house brand. there are not manufactures . 30 % get trouble in less than one year.
Plasma TV available only 42 inc and above screen. prefect in total pictures quality suited for moving image / sports fast action movies with out so call " motion blur ".
