The newest TV technology that has risen to change the industry horizon, provides another consideration to your purchasing
decision. That technology is called LED TV. LED TV's are offering shockingly thin panels, bright images and unique designs that are
changing the way we think about flat panel televisions. LED
Knowing that LED’s are in fact, LCD TVs, what makes them better? There are a number of features that are inherent to LED’s that
make them the backlight of choice. A traditional LCD uses a ‘Cold Cathode Florescent Lamp’ (CCFL) as the backlight. CCFL
backlights are inexpensive, durable and versatile; however CCFL’s create whites that are slightly blue, which in turn lowers the quality
of the entire image. A TVs ability to create accurate blacks and whites will determine the overall quality of the image. The ‘Light
Emitting Diode’ (LED) is more expensive than CCFL, and offer the same applied durability and versatility; However, LED’s create
more accurate colors, a brighter image, more compact size and lower energy consumption.
The aesthetic difference between new LED TVs and Traditional LCD TVs is the depth. ‘Ultra-Slim’ LED TVs are extremely thin and
lightweight, some models up to 55” in size and less than 1” thick. Samsung was the first to release the ‘Ultra-Slim’ LED TV design, and
was a big attraction at the Consumer Electronics Show 2009 in Las Vegas. The typical Ultra-Slim LED uses a design called ‘LED
Edge Lighting’, or ‘Edge-Lit’. This design places the LED backlights around the edge of the screen; no actual backlights are behind
the screen. Traditional LCD and LED backlighting is known as ‘Direct Lighting’, because the light source is located behind the screen,
and fires directly towards the viewer.
The Edge-Lit LED’s fire inwards, towards the center of the screen, and are redirected by prisms out through the LCD Panel. This is
how Samsung, and other ‘Edge-Lit’ LED TV manufacturers achieved such thin panel designs. Additionally, this design further
decreases the energy consumption of the TV because there are fewer lights used in Edge Lighting than with a Direct LED design.
There are new LED TV products being released right now that offer Ultra-Thin designs with direct LED lighting. Direct LED Lighting is
a better design for performance.
The LED TVs use less energy than their traditional counterpart, and produce far less heat. I have left an edge-lit LED TV on all day,
with little to no heat emanating from the set and it was cool to the touch. Heat is the enemy of all electronics; the cooler the better.
This information scratches the surface regarding LED and traditional LCD Televisions. When it comes to electronics, baby steps is
the best path to making the proper purchasing decision, ultimately saving you time and possible hundreds of dollars.

"Intro to LED TV Technology and Benefits"
The picture depicts the energy consumption of a 32" LCD and 55" LED TV. As you
can see, the 32" LCD TV uses slightly more energy than the 55" LED. This example
is from CES 2009, and technology and energy usage has reduced even more!
