What is the key difference between an LCD and an LED TV?

Have you ever found yourself strolling throughout the aisles of a Best Buy or Fry's feeling utterly oblivious because you're struggling to find out what the difference is between each television?

Have you after a while of staring, tried to ask a salesman regarding the differences, just to get a non informative, non descriptive answer?

If you answered yes to any of these questions, then you came to the right place. I'm going to break down the exact differences between an LCD and an LED TV.

Once you're finished going through the facts in this post, you will be much keener on the subject.

Afterwards you could return to the Fry's or Best buy you went to and show the salesmen some stuff.

Don't be misled; an LCD is in fact in LED:

Before I begin, let me make something clear, on this whole LCD vs. LED debate. An LED is indeed an LCD because they both utilize what's called liquid crystal display.

This basically means that both of them function by using liquid crystal display (LCD) flat panels to present their images.

The main difference when it comes to an LCD and an LED is the type of back lighting each one uses.

Other than that, there's really no such thing as pure LED television. Now that I've made things a little clearer, you can start to view both televisions as an LCD and an LED-LCD TV.

What kind of backlighting is there?

As I mentioned previously, the major difference ljusskyltar led between an LCD and an LED television is the kind of backlighting it utilizes to present its picture.

An LCD utilizes what is referred to as a cold cathode fluorescent lamp (ccfl) for background lighting. The fluorescent lamps use a plastic shield before the censors to smoothly distribute the light.

LED stands for light emitting diode, which are comparable to the lights you put on a Christmas tree, only quite smaller. This is where the discussion between LCD vs.

LED starts to unravel when referring to the quality of the images. The LEDs are set in rows and contrary to the LCD, it doesn't function using a plastic shield to display its lighting.

The brand new LED models are equipped with precisely placed censors in the LED as well as the crystal display to monitor the picture being conveyed.

These sensors are utilized to analyze the 1's and 0's data that is being emitted and modifies the color being displayed pixel by pixel, so it's capable of using its light more effectively. Think of it like flip sunglasses.

These sensors function in the similar manner that flip glasses do, only utilizing several different types of shades. Utilizing this kind of technology on an LED HDTV, you are able to view much richer blacks, sharper image color and a more luminous picture.

This is the main reason an LED can display for you a more vibrant picture. So when it comes to the LCD vs. LED debate, what you're actually referring to is LED back lighting vs. fluorescent back lighting.

What does full backlit and edgelit mean?

There are generally two ways the LED HDTV utilizes back lighting. Backlit and edgelit. The main feature on the full backlit is that it's utilized to improve the contrast levels by turning off the LEDs that were selected and using a function referred to as local-dimming. This boosts the amount of blacks in particular areas of the picture on the television.
