Led Tv

Consumers who want a realistic, crystal clear picture when watching TV know that they need an LED TV. The problem is that too many salespersons will lead them astray, saying that an LED TV is nothing more than an LCD TV, and this couldn't be further from the truth. It's like saying a Hyundai is the same thing as a Mercedes. Yes, an LED TV is a type of LCD television; however it is so much more because of the technology that goes into lighting up a picture perfect screen.

LED's Replace Outdated CFL Backlighting

Traditionally, liquid crystal diode (LCD) TV's had backlighting provided by compact fluorescent lamps (CFL) that were bulky, had a slow on/off response, and could not provide realistic color qualities. With the advances in light emitting diodes (LED), television manufacturers are now able to blend the best of LCD and LED technology to provide the truest color and brightest, sharpest pictures available. As a side note, CFL's are manufactured with mercury and gasses that are harmful to the environment, while LED's are eco-friendly..

Two Types of LED Backlighting

The first thing to understand about LED TV's is that there are two basic ways in which backlighting is provided, local dimming and edge lighting. While edge lighting (where the LED's are placed around the perimeter of the inside of the screen) allows for thinner televisions, local dimming screens are far superior in performance. In local dimming models, banks of LED's are located directly behind the panel which allows for better blacks and a higher contrast.

Recent Advancements in LED Local Dimming Technology

Luckily, local dimming panels are now comparable to edge dimming screens in terms of how thin they have become. LED technology offers the ability to provide tiny banks of LED's that are able to significantly reduce the thickness of the panel. In fact, with these newer versions, it is virtually impossible to tell them apart based on size without reading the product specs to determine which type of backlighting is provided.

Colored LED Backlighting Takes the Trophy

In recent studies, experts have determined that the truest colors with the whitest whites and the blackest blacks can be provided by colored diodes in the local dimming sets. While many experts feel that CFL and LCD lighting provide similar contrast in blacks and whites, there is no comparison when it comes to true color. Since LED's are able to emit any color in the visible light spectrum, colored LED banks behind the panel provide for the most realistic color viewing experience.

In a few words, this boils down to the fact that LED TV's are, without a doubt, able to offer viewers the clearest, cleanest pictures with the most realistic colors available short of those provided by natural sunlight. But, there are so many other advantages to an LED TV that are not commonly known. Here are the top ten advantages of LED TV's that consumers should be aware of prior to purchasing their next television:

Top Ten Advantages of LED TV's

1) Most realistic color.
2) Ultra sleek panels (screens).
3) Longest lifespan of lighting.
4) LED's contain no mercury or gasses.
5) Quickest on/off response ' no warm up period.
6) Best response for gaming.
7) Local dimming has best contrast and black levels.
8) Durability in terms of backlight lamps.
9) Response rate and refresh time for video viewing.
10) Lowest power consumption.

Flat screen TV's have been around for a few years now and there is no surprise that for each of these years, a newer, brighter and more efficient model has made it onto the market. However, with the newest LED editions resetting the home cinematic experience bench mark, it won't be long before every house has one.
