LED TVs have become more and more popular among consumers, who tend to choose these over other top models. Many people do not fully understand however, how an LED TV differs from other televisions. Keep reading the following information in order to better understand some key differences that LED TVs offer, that other televisions do not.
First off, people should understand that an LED television is, in fact, an LCD TV. What makes a regular LCD television differ from an LED TV is how it lights up the screen. Each TV uses different technology, for example an LCD TV lights up the screen by using fluorescent backlights, and an LED TV uses LED backlights to light up the screen. It is also important to know that LED TVs have two main ways that they use the backlights to light up the screen.
The first way that backlights are used in LED television sets are known as “edge lighting”. This is a technology in which the LED lights are evenly spaced along the outer edge of the television screen. The screen is lit by the LED lights shining the light towards the middle of the screen.
Edge lighting gives the benefit that the television is able to be produced in a very thin model. The disadvantage of this however, is that the screen is not able to portray deep black areas and the middle of the screen tends to be brighter than the rest.
Full array, or full LED, backlighting is the other type of backlighting that can be found in LED TVs. This form of backlighting consists of LED lights being placed in a consistent spacing across the whole area of the screen.
The main benefit of having a full array LED TV is that it provides what is called “local dimming”. Local dimming is a process in which each LED light, or even a group of LED lights are able to turn on and off independently. Many people prefer this because it allows more contrast in colors, meaning dark spots on the screen are darker and bright spots are brighter. One disadvantage of a full array television however, is that it is not able to be as thin as the other model.
Since LED televisions are designed differently than other LCD models, there are other benefits that can be found in an LED TV that can not be found in an LCD TV. A few of these benefits include that an LED one uses less energy than an LCD TV does. They also do not use any mercury, whereas some LCD models do, and LED televisions give a more balanced array of colors.
It is very important that people understand the difference between regular LCD TVs and LED televisions before they invest in one. One area to consider is whether or not it is important to have a thin TV. Another consideration is whether or not having a high contrast in colors is important. Because both types of LED TVs offer benefits, it is really up to personal preference as to which one is better to buy. One thing for sure though, LED TVs are pleasing to many people.
