Over the past decade home entertainment technology has really taken some huge leaps forward. Today, the task of buying a new TV is not just a matter of picking your favourite brand or buying the largest size you can afford. There seem to be more options than ever, and this has certainly led to a lot of confusion among consumers. With that in mind, what exactly are the main differences between the different types of TV, and which is the best?
Plasma TVs are one of the older types of flat screen. They are relatively cheap to produce meaning that prices are generally low for the screen size, which led to plasma becoming a popular choice with consumers who wanted to get the largest screen for their money. These TVs use a gas, which then turns into plasma when an electronic current is passed through it; the plasma then emits the light to create the pictures. This results in a high quality, realistic picture that doesn't suffer from motion blur. It also offers a particularly wide viewing angle.
However, plasma screens do tend to only have a lifespan of about 10-15 years and do use a relatively high amount of energy, which is now frowned upon as many consumers are trying to become more environmentally friendly. Plasma screens are also quite thick, and are very heavy for their size, so they can be awkward to move. The screen is also fairly susceptible to glare, especially in bright rooms.
LCD TVs can trace their roots back to computer monitors and were first introduced at around the same time as plasma TVs. These TVs use the same basic technology as your pocket calculator screen and are backlit with florescent light. They have a much longer lifespan than plasma screens, something in the region of 30+ years, and also use much less power. Traditionally LCD prices were higher than plasma, but as new manufacturing techniques have evolved the prices are now rapidly falling.
While LCD TVs are available in a wide range of sizes, they do offer the worst performance of all the flat screens though, not only do they have the lowest contrast level but they also have a slow refresh rate meaning that motion blur often occurs. The viewing angle is also much narrower than that of plasma TVs, which means that it can be difficult to find a location that offers a good view for everyone, especially in smaller rooms.
LED TVs are actually the next generation of LCD screens, as they are based on a similar technology but use LED backlighting instead of the florescent backlighting found in traditional LCD screens. The new backlighting technology means that they are able to deliver a much more dynamic picture quality, they also use significantly less power than even the most efficient LCD TVs. LED screens can be made to be extremely thin, so they offer consumers the ability to place the TV practically anywhere - indeed it is now commonplace to see TVs fastened to the wall in order to save floor space.
As this is still a relatively new development, LED screens do tend to be more expensive than their LCD counterparts. However as LED TVs become more widespread the cost of production is expected to drop significantly, which will be reflected through dramatically lower prices in-store. Having said that, LED technology is considered to be the most reliable of all the flat screen formats so many people don't mind paying a little bit more.
The world of home entertainment can certainly be a confusing place, especially as new advances in technology seem to come along on an almost monthly basis. Hopefully this article has shed some light on the current generation of flat screen TVs, so at least you can stand a fighting chance the next time you venture into the home entertainment section of the electronics store.

Plasma TV, LCD TV, rear projection TV, I think I'm gonna scream! The trend toward ever-bigger TV screens is evident. One reason is the improvement in picture quality in a growing number of TVs with 1080p (1920x1080) native screen resolution. Native screen resolution indicates the number of pixels, or picture elements, on the screen. The more pixels, the finer the detail a screen can display. You can appreciate this level of detail most on a 50-inch screen, or larger, but you might see some subtle improvements on 40- to 47-inch screens also. 720p sets have been the front-runner because of price, but now you'll find a growing number of 1080p sets at lower prices, giving you much more of a choice.
So lets break down some of your choices. LCD TVs, come in common sizes of 17 to 52 inches and are very slim. The pros to a LCD TV are the wider range of sizes, and greater choice of 1080p sets than plasmas. They have brighter images and most have no reflections from the screen. They are lighter weight and they use less power. The cons are most have limited viewing angle. They do not match plasmas for deepest blacks and smooth motion.
Plasma TVs come in common sizes of 42 to 60 inches and are also slim. The pros, they have virtually unlimited viewing angle. Much deeper blacks and better contrast than on LCDs. There is no motion blur and more screen for the money. The cons, shiny screens show reflections in bright rooms. Images may leave a temporary or permanent impression. They use more power and there are fewer 1080p plasma sets to choose from than LCD 1080p sets.
Rear-projection TVs come in sizes of 50 to 70 inches. The pros, you get the most screen for your money with a wide selection of 1080p sets. The cons, they are much bigger and most go 12 to 20 inches deep. There is a narrower viewing angle than on plasmas. You must periodically replace the bulb, which can run you from $200 to $300. They have been more repair prone.
Is there a clear winner? The vast majority of consumers are buying both the LCD and plasma flat panels rather than rear-projection. Neither LCD nor plasma are the clear winner for quality, there are excellent sets of both types available. Size does matter. Carefully choose the size screen you are most interested in and fits the size of your room best and that may dictate the type set you buy. If you truly want a jumbo screen for a large room and home theater, then rear-projection is the way to go. Obviously for the smaller sizes you have to go with the LCD. They are generally brighter than plasma and have less reflections, so they look better in bright rooms. LCDs are also better for playing video games or for use as a monitor because they are not subject to burn-in from fixed images displayed for a long period as plasma TVs are.
For the overlapping sizes, you must look at the viewing angles of your room and of course your budget. A 1080p set is the way to go, especially if your considering HD programming. But don't completely rule out the 720p sets if you are going for the smaller size screens. In the smaller sizes some 720p sets are almost indistinguishable from the 1080p sets.
One last item of thought, skip the extended warranty. LCDs and plasmas have been very reliable for the first three years which is the period covered by the extended warranty, so there's little sense in spending several hundred dollars for a warranty.
