LED Televisions - A Beginner's Guide

Anyone that knows about technology also knows the salespeople in stores can be surprisingly ill informed in regards to the products you can choose from. If you've ever been told that creating a four core processor quadruples the rate of your PC or that the 600Hz subfield drive is 10 x better than 60Hz refresh rate then you'll know that sometimes the sales agents know nothing more than what's written about the product and they are just as susceptible to jump to (inappropriate) conclusions as anyone else. This article is here that may help you gain a better knowledge of how LED TVs work. It does not contain any tips or recommendation but does provide basic information to improve your overall knowledge.

How do LED TVs work?

It is a type of misconception that LED TVs use an entirely different technology than LCD panels. This has largely come to pass because industrial and commercial LED screens exist designed to use clusters of LEDs per pixel. However domestic "LED" TVs are in fact LCD screens which use LEDs for backlighting (instead of cold cathode fluorescent lamps (CCFL) which are more widely used).

What will be the advantages of LED TVs

There are several advantages to utilizing an LED backlit LCD TV when compared with using a CCFL backlit model. These include;

• A greater dynamic contrast - Which in human terms implies that blacks are blacker.

• The potential to be extremely thin - LED back lighting uses up significantly less space than other methods which means that this type of TV could be less than one inch thin.

• Potential for wider colour gamut - Depending about the technology used you will find the potential for LED TVs to possess a far wider colour gamut than non LED models. This comes down to making blues and greens more vibrant compared to they would be otherwise.

• Cheaper running costs - Because they are more energy-efficient than just about any light source LEDs are less costly to run. For an average TV this normally means knocking a fifth from the annual running cost.

• Less environmental damage - CCFL backlighting necessitates use of mercury which implies that disposal could be particularly harmful to the environment.

• Better viewing angles - LCD TVs are notorious for experiencing narrow view angles (i.e. if you tilt the screen it appears funny) but there are rumours that LED TVs have problems with this less and to a certain extent this is correct but largely as a result of the fact that LED technology is usually used only on flagship and luxury models - which by their very nature are apt to have been better engineered.

Can LED TVs do 3D?

No. As a rule the TVs with 3D capability are the flagship and quite a few premium models produced which ensures that almost without exception they'll use LED backlighting so it can be fair to express that all 3D TVs use LEDs but not all LED TVs are 3D
