While many people might turn to the plasma because of the great price, they often overlook the vast differences and advantages the LED TV offers. While an LED will be a little more than plasma, the old term “you get what you pay for” certainly applies. For those who like video games and like to sit close on the screen, an LED will have the quality one needs for a superb picture, from any room angle.

Screen size is something that comes into play while shopping for a TV. The LED’s range in size from 32-70 inches. When looking at LED televisions, the larger the screen, obviously the higher the price. If one has the extra money, they should go for an LED over other TV styles. The technologies in these TVs are better, making the picture bright and colorful.

The internal parts of a LED TV make it light to carry. Some people fear that the LED, like light bulbs, use mercury, this could not be further from the truth. Because LED TVs use Full Array back-light methods, the colors are enhanced and vivid. Because of this back-light, no color is leaked on darker scenes; this is why the black color seems true.

The lifetime of the LED TV’s are extended and said to last longer than other models on the market. They are made to last between 5-6 years, which is excellent for today’s ever-changing technology. Whether for games or for movies, an LED television can provide years of viewing enjoyment.

Many people have their heart set on a certain size of screen for their living room. While most homes can accommodate that size, what about those that can’t? This causes a great deal of returns, because people under or overestimate. Make sure to measure before heading to the store, whether it is going on the wall or in a cabinet, space is limited.

Nowadays, you can see a lot of people spending hours and hours together shopping for a perfect television which would occupy the center-stage of their respective living rooms. With the ubiquitous presence of ever-confusing marketers of the television-manufacturing companies, the decision is becoming all the more difficult. So, let us understand the technologies before you splurge your hard-earned money on them.

Earlier, you used to find televisions with only one kind of technology. They were called ‘CRT TVs’ (Cathode Ray Tube). With the help of electron guns, coils and a fluorescent screen, the CRT TV was able to produce a viewable image. Now, there were problems with this technology:

1. A number of components were used to manufacture the television which made the processes of production, repair and maintenance difficult

2. The individual components were also bulky which made the television quite heavy

3. Some of these televisions had a problem of ‘Image burn-in’ (Permanent discoloration of areas on electronic display) and a problem of ‘Image Loss’ at the boundaries of the display

4. These televisions produced noticeable flicker at low refresh rates

5. They consumed high power and generated a lot of heat

To overcome the drawbacks of this technology, manufacturers started producing LCD (Liquid Crystal Display) televisions. An LCD is a flat-panel display that makes use of light modulating properties of liquid crystals. Now, these liquid crystals do not emit light by themselves, so a backlighting source is required in cases where there is higher power consumption. To understand this, you need to take note that there are two kinds of LCDs: ‘Passive Matrix LCDs’ and ‘Active Matrix LCDs’. In ‘Passive Matrix LCDs’ like ‘Alarm Clocks’ and ‘Calculators’ where the power consumption is less, a backlighting source is usually not required. Contrast this with ‘Active Matrix LCDs’, where some sort of backlighting mechanism is required. Now, this backlighting has been traditionally achieved with a ‘Cold Cathode Fluorescent Lamp’ (CCFL) in an LCD Television. So, the ‘CCFL backlit LCD’ television overcomes the problems of CRT in the following fashion Continue reading »
