Are you looking to buy a new television?

A good 70% of the people do admit that they have made a wrong choice in buying their television set. It cannot be said in any way that anyone among them is a clear leader but some characteristics do put one in front of the other.

Are you still using the CRT, TVs. They consume a lot of space and you cannot view the images also very clearly from different angles and you cannot get to see a display of high-definition picture.

HDTV technology has gone for a sea change and has given the viewers a chanced opportunity to view superior images and listen to digital sound.

Possibility is that you have to do a selection from LCD, LED or plasma TVs. These are the most common TV sets which are found in the market these days.

Need to know

How an LCD TV works?

LCD stands for liquid crystal display. This type of monitors has become popular as computer monitors before they made their entry as televisions.

The screen is composed of two sheets of polarized glass. In between the two sheets of glass there is a solution made of liquid crystals. The glass is back-lit by a fluorescent bulb.

The crystals start moving when electric current flows through the liquid. The polarized glass permits certain wavelengths of light from the bulb to pass through. This leads to creation of thousands of tiny dots, or pixels of color that finally make up the picture on an LCD TV.

How an LED TV works?

The latest kind of HDTV flooding the market makes use of LED technology. Just as an LCD display, the LED screen makes use of a liquid crystal display that is sandwiched between tow sheets of polarized glass. Here LED screens make use of light emitting diodes rather than using a fluorescent back-light to light up the picture.

How a Plasma TV works?

Certain shortcomings in the LCD displays lead to the birth of Plasma TV. The plasma screen TV has two panes of glass that goes to the making of flat screen.

Plasma TVs have chambers which are filled with xenon and neon. The moment electricity runs through these chambers, the gas changes into plasma. The plasma moving through the chamber, gives out photons that show in various colors.

Let us look into some of the following factors which you should consider before making a final decision while buying a TV.

Contrast Ratio

For proper display of pictures a high contrast ratio is desirable. It displays the differences between the darker and lighter sections of the screen amazingly well.

It is a known fact that plasma TVs are better compared to LCD and LED TVs as plasma TVs individual plasma cells, which on its own turn themselves off on the darker parts of the screen.

LCD TVs have a single liquid crystal and when the TV has to show dark pictures, the CCFL backlight of the LCD only dims itself, thereby making the blacks very unimpressive.

But LCD TVs powered with LED backlight have a slender advantage as individual LEDs twist themselves into an “off” position in those dark parts of the screen thereby giving a more persuasive black than LCD TVs.


Whenever you start comparing the three types of TV, color is one factor which you should take into account. How the color is reproduced in the capture image is an important yardstick which you should consider. The objective is to reproduce colors which are very close to looking original.

There is only a marginal difference of the color reproduction between the three technologies. Among the three, Plasma TV holds a slight advantage though the other two also are equally good. But in case of LCD the images seem washed out.

There are LED TVs with RGB colored backlight systems and certainly the best among the lot. But one thing they are rarely available and also expensive.

Power Usage

Different amount of electricity is consumed by the three types of TV and in the long run it plays a key role to tell whether you have chosen the best one. This point is ignored by many and 60% of the people buying TV do not heed to this point.

Plasma TV consumes a lot of power as all their pixels are lit all the time as compared to LCD and LED. The LCD TVs hold a slight advantage than the others but even in LCD TVs the CCFLs are on all the time. This leads to extra power consumption but not as much as plasma screens.


Motion is another factor which determines how we see an action on the screen. The plasma TV holds an advantage with a high refresh rate which helps the smooth motion of images. As far as LCD and LED TVs are concerned they have improved their performance in recent times.

LCD and LED TVs have models that have feature refresh rates of nearly 200Hz which is really fine but plasma TVs can have refresh rates higher that 480Hz

Viewing Angle

This is another important factor. It refers to the angle which the image of the TV can be seen. In some cases you may not get the chance to sit in front of the TV and may have to sit around it. Thus viewing angle parameter becomes a critical factor.

Plasma TV holds the advantage when it comes to viewing angle. As in case of plasma TVs all the pixels are lit, the image formed on the screen can be viewed with same clarity from any angle.

If you are observing LCD screens the quality of the image drops significantly as the viewing angle increases. In some cases the LED TVs fare well over the LCD screens.

How long it will survive?

Another vital parameter is the big question; how long the TV you will buy survive. This factor is measured in hours and most manufacturers claim that their TV will last around 100,000 hours of use.

Among the three LCD screens last the longest without any deterioration in the quality of the picture and also brightness. As far as the Plasma screens are concerned they show a tendency to lose brightness and detail far sooner than others. Again there are burn-in issues which the plasmas suffer from but the advent of technology this factor has been reduced to a great extent.

LED TVs the latest and the newest of the lot has gone through the heavy testing but still not been able to remove some of the major concerns and are considered not yet to be safe and reports indicate they are not very positive as far as lifespan is concerned.


Who can ignore that price is a key factor which shapes our opinion about which type of TV to buy. There are buyers who consider the price factor first rather than other factors like image, sound or color.

But a high price does not always mean that the type of TV you are buying is a super quality in respect to all other factors. Plasma TVs are considered the best value for your hard earned money. They have now been in the market for a long time.

But surely if you consider the price along with its features then you are settling for something not so good as it does not boast of some excellent features.

As far as the LED TVs are concerned which are the latest entry are priced at a higher range than both LCD TVs and plasma.

Finally what type to choose?

Is price the only factor weighing into your mind while buying or considering a TV, then look no further than plasma TV? Here you get the best viewing angles and also the color reproduction.

But don’t go for low priced plasma as you may run the risk of high power consumption, burn-in and shorter lifespan. The plasma TV cost more to produce as there is use of noble gas. They incur a high cost to repair and in most of the cases they cannot be repaired at all.

Again what you decide to watch, how often you watch TV in combination with price tag will play role.

So there would be different models which may attract you also and screen types. Do a comparative study of each of them in relation to picture, price and all other related factors which contribute to a happy viewing experience.

Surely this guide in highlighting the differences between LCD, LED and Plasma would help you understand better the comparative advantages and disadvantages between the three types and each of them offer some excellent features to choose from.
