When it comes to flat screen TVs you have three main choices: LCD, led and Plasma. Whether replacing an old, worn out TV or just deciding it is time for an upgrade, it is worth it to look into the different types of flat screen televisions and decide which one is best for you. Each of these styles may look similar when they are not switched on, but the way they operate inside can have a big impact on your viewing experience.
LCD and Plasma TVs despite having a good picture quality often can not display black on the screen very well. This is because they both utilize a fluorescent lighting system to illuminate the screen. When the blacks are more of a grayish color it comes off to the human eye as fuzzy and unclear. This happens because the light sometimes just shows around the diodes within the tubes.
Despite the fact that the liquid crystal diodes used in fluorescent lighting can produce any color on the spectrum, the fluorescent lights used in Plasma and LCD televisions are not high enough quality and thus limit the colors of the screen. led TVs, on the other hand, make use of back-lightning and can produce a wider range of colors, this is where backlit led TVS have an edge over LCD and Plasma.
led TVs have two different set-ups when it comes to back-lighting. Some led TVs have a completely back-light behind the screen while others have them placed around the edges. Both of these set-ups consume less electricity than the fluorescent systems used by LCD and Plasma TVS, but they do have their own draw-backs.
led TVs with edge lighting are light-weight and thin, but the lights are always on just like fluorescent systems and despite the fact they use diodes to create light the black colors on the screen are still not as deep and rich as backlit led sets. The backlit models have that sharp, rich black color but they are not as thin as the edge lit models. But when it comes to having to absolute best, sharpest image a backlit led TV is definitely the way to go. It is the prime choice of many serious TV and movie watching consumers.
