LED TVs “ARE” LCD TVs…Don’t Get Bamboozled

GREAT POST by Heathaplex Vision on LED/LCD TVs

LED TVs “ARE” LCD TVs…Don’t Get Bamboozled

I can’t take it any more folks!!!! I finally reached the point where I feel I must inform the masses and set the record straight about the so-called new LED Televisons. All those LED TVs ARE LCD TVs!!! Don’t fall for all the false advertising.

As I was reading this  Sunday’s Best Buy ads, I ran across a full page Samsung television advertisement showing three LED TVs on sale. No where does it mention LCD, but that is exactly what you are buying. This is why it is important to educate yourself on all these formats. You can learn all about it by ‘Googling’ it.

LED stands for Light Emitting Diode. LEDs are everywhere around us and have been since the early 1960s. LEDs produce light. Traditional LCD televisions are backlit via fluorescent light which is larger, consumes more energy, and it not as brilliant as LED backlit LCD televisions. Did you catch what I said here…..LCD televisions are either backlit with flourescent light or LED light. It is as simple as that. But, Best Buy and Samsung would have you believe LED TVs are something completely new to the world of high definition televisions and even get you to pay more than double for it. Even when I visited Best Buy, the sales person couldn’t even explain what LED technology was and blindly went on to tell other customers this was new technology and different than LCD. Sorry Best Buy dude….this has been around for a long time.

There are some great things about LED that you should be aware of. First, it consumes far less power than fluorescent backlit displays. Second, the lighting is smaller, hence the thickness of televisions can be smaller, which is another major advertising plug. Third, they produce higher contrast ratios and are a bit more brilliant (black-levels are improved over traditional flourescent backlit LDC TVs), but not as good as the numbers would have you believe. Fourth, you need to understand there are two types of LED televisions: those that are completely backlit (Full Array) and those that are edge-lit. Edge-lit have diodes around the edges of the television and throw light from the sides to light up the display. They are not as good as the full backlit (Full Array), but cost a lot less. Also, Full Array LED backlit displays can turn off light to individual areas of the screen which produces more realistic black levels and better contrast rations. I highly doubt you’ll find many Best Buy reps who truly understand the difference between Edge Lit displays and Full Array displays, but you should know what you are getting into before you pay up to twice as much for an LED-lit display vs a Flourescent-lit TV.

Bottom line folks, do your research before dropping this kind of cash on a television set. All it takes is a few minutes on the web and a few Wikipedia entries to learn about the different technology on the street. LED-lit LCDs are great televisions and produce some fantastic pictures, but you’re still getting an LCD television. As a movie viewer I still prefer Plasma because of the true black level reproduction, clarity, and the fact I have it located in a fairly dark room. If you prefer LCD televisions, definitely take a closer look at the LED versions on sale. Prices will soon be dropping as people begin to understand the major differences with these backlit displays and the fact that they are still buying an LCD television set.

Happy New Year to you all!!!
