The Difference Between LCD TV and LED TV?

When LED TV first came out everyone raved of the quality of the video display but were sort of taken aback with the price. This is one expensive TV so it would be best to know the difference between the two before you go out and buy either one.

First of all, there is only one difference between the LCD and the LED – lighting. So if lighting is the only difference, why is it marketed as something different? Continue reading to find out some basics of this new and innovative technology.

• LEDs is just LCDs but the LEDs use LED lights, or light emitting diode, for the back lighting while the LCDs use fluorescent CFL. Both of these TVs use LCD or liquid crystal diode technology for the screen.

• The LED TV has two kinds of back lighting:

o Edge lighting – the LEDs are found at the edge of the panel which can allow for very thin construction. This is the reason why LED TVs are so much thinner compared to the LCDs.

o Local dimming are those which are found behind the panel or screen and these can be controlled to either increase or decrease the back lighting where there are dark and lighter areas. Again, because they can make the construction thinner, the LED TVs are flatter than the regular LED flat TV.

The advantage LED has over LCD is because it can adjust the contrast and black levels. LCDs had a problem of dim displays. The LED can dim the back lights in the areas where the screen are expected to be dark but lightens the areas which are supposed to be light. In fact, LED produces brighter whites than the fluorescent LCD. However, newer innovations on the LCD have corrected this light and dark issue that this is now considered corrected.

LED also offers more accurate colors compared to the LCD. Somehow the reds are redder and the yellows brighter on the LED which can be darker in the LCDs. Again, new technological innovations on the LCD have corrected the issues.

The short of it is, there is not much difference between the two TVs and really if you do not mind the darker image, which have already been corrected as of this writing, then the only thing that should make the final decision for you is the cost. Definitely the LED is much more expensive than the LCD and it is flatter too, a fraction flatter. So the choice is yours.
