LCD Vs LED Debate Broken Down! Learn the True Differences Between Both TVs

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 tinytask for mobile 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 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.

The edgelit’s most obvious advantage is that it gives the HDTV the ability to be exceptionally slim, which makes it a lot less heavy and much simpler to mount or pick up if you need to. Contrary to the full back light LED television, the edgelit uses LEDs to the outer frame rather than on the back of the panel. A lot of the most recent edgelit LED televisions now utilize local dimming as well. Just remember to consider the fact that the edgelit will display fewer dimmable segments when compared to the full back LED television. The difference is substantial, much like comparing thousands to millions. To sum it all up the full backlit LED television can achieve more richness in color and better local dimming.

LED HDTV and local dimming:
TVs have significantly evolved since the good old tube TVs. All LED TV sets that incorporate the local dimming setting are proficient in recognizing specific dark areas of the image that is showing on your television. This provides the ability for more detail to shine through on the scenes that are noticeably darker than others. Local dimming functions by turning off certain pixels, allowing for a much better contrast ratio and deeper levels of black. The pixels turn off then on as a result of the ambient lighting that’s surrounding you. Think of this like when you’re trying to watch television with the glare from the sun beaming through your window, or the room light piercing through your TV screen. The LED HD television automatically converts the elements of your image as needed, so you are able to keep admiring the image on your TV screen without missing your favorite scene. This is clearly a really nice feature to have if you ask me. LCD only televisions don’t include this option.

Is an LED Really worth the money?
The simple answer is absolutely! This is obviously just my own two cents on the matter. I’ve worked with high definition televisions long enough to know the actual benefits of an LED television. Frankly, I actually do not think this subject is relevant, since soon all TVs will be LEDs (LCD-LED). As technology moves forward, LEDs keep getting more and more sophisticated. Pure LCD HDTVs are yesterday’s technology and will soon be obsolete. In order to keep things simple, these are the overall points to keep in mind when making the decision to get an LED TV in place of an LCD only television; LEDs work off less power, offer you a much more accurate response time as opposed to fluorescent lighting, are equipped with local dimming, are noticeably lighter and offer you overall greater image quality.
