What Is the Difference between LED and LCD TV

It's just all kinds of wrong When they call the latest kind of television “LED television”. To begin with, everyone knows that those huge sports stadium screens are LED-studded panels. Those are the real LED TVs that people know about. Call the 32-incher at Best Buy an LED TV, and people right away wonder if it's the same technology they've seen in the stadiums, only shrunk to living room size. Now nothing could be farther from the truth. The other reason it's misleading that they call it an LED TV is that it makes you think that it's a kind of television technology quite akin to the way LCD is a kind of television technology. Which it is not. So let's get to the bottom of this – what is the difference between LED and LCD TV?

Let's say that you're sitting in a room at night and you're reading a book. The book itself is not luminous or anything of course (it's a regular paper book, not an iPad), so you need to turn the lights on. You have two kinds of light in the room. One is a regular fluorescent strip light, and the other is one of those expensive new LED lighting fixtures that you got for $50. What if you turned the LED light on, and someone came in and remarked, “Oh, you're reading an LED book!" You'd look at them like they were crazy – what does it matter what kind of light you are reading the book by? That doesn't change the nature of the book you're reading!

And that's exactly the answer to that question about what is the difference between LED and LCD TV. They are both LCDs – exactly the same thing. LCDs, like printed books, need to be lit by a good, strong light if you are to be able to see anything. It can either be a traditional fluorescent strip light, or it can be one of those expensive newfangled LED lights.

What is the difference between LED and LCD TV? In main, there's just one question you need answered – is one kind of light better than the other? Well, in many ways, LED really is better.

You’ve noticed how those LED televisions these days are nearly razor thin, haven't you? Well, even if you've never noticed it, the companies do try their best to bring it to your notice with all their high pressure advertising.

Yes, LED-lit LCD televisions (yes, that would be a far more accurate way to name LED televisions) are 50% lighter and thinner than a regular LCD TVs (ones that are lit by regular fluorescent lighting except that they never say anything above fluorescent lighting in the advertising).

If you don't really care about how much your TV weighs for how thin or fat it is, if you only care about picture quality, you do have to know that LED televisions are brighter, they offer you richer and more vivid colors, and they give you much better contrast.

But all of these are "potential" areas of improvement. Most LED TVs on the market these days, even ones by Sony, are models where they use lights that are just mounted along the edge of the screen (on the inside). In other words, they are just using the LEDs exactly the way they would use fluorescent strip lights. These televisions give you no picture quality-related improvements. They just give you a thinner and lighter television.

If you're really looking for picture quality improvements, you need to go with a panel that they advertise as direct-lit LED or RGB LED. These are quite expensive. These are the ones that give you the real advantages.
