Purchasing a new television can be a very overwhelming process. Since a TV isn’t something that you buy very frequently, and technology moves so quickly, it’s very common for most of the terms to seem foreign. As different technologies compete for the best consumer option, there is a larger need for the buyers to be informed about what they are looking for in televisions. The most common question in consumers minds today is: what is the difference between LED, LCD, and Plasma TV’s?
This is a very important question, and it is the first one that should be addressed when thinking of a new TV. In order to understand the differences, it’s important to determine what makes a TV image a very good quality. The answer is that it is all in the way that the screen is lit up. The key to very real feeling images is the ability to display a true black color. The more true the black is, the more depth the image seems to have, and this gives the viewer much better contrast and a more lifelike display. Now that we know that lighting is the key aspect, there still is the question: what is the difference between LED, LCD, and Plasma TV’s?
The difference between all three of these types of televisions is the way that they light up the picture. In a Plasma TV, the display is a sandwich of plasma gas that is controlled by precise electrical current to determine the colors and the contrast. This type of display has the ability to show black colors better than any other display, which makes it the current technology leader. LCD (Liquid Crystal Display) is similar to the Plasma in that it is a sandwich of liquid crystal that is manipulated by precise electric impulses. The major difference, however, is that Plasma displays create their own light, whereas LCD displays require a back light in order for the viewer to see the picture. In traditional LCD displays, they use lighting tubes behind the image, but LCD technology is evolving to catch up to Plasma displays. This is where LED comes in. LED is simply an LCD TV, but instead of using light tubes behind the picture, it uses a matrix of light emitting diodes. This is much more accurate than light tubes since it can fully turn of the black sections of the matrix to allow for a deeper black.
While LED has brought LCD displays much closer to Plasma, Plasma still has the edge. Even in current LED TV’s, light still leaks from the light diodes that are next to the black which pollutes the depth ever so slightly. As LED becomes more and more advanced, it will surely catch up to Plasma, and the gap is closing quickly. The most important question still remains, and that is of course price. In terms of price, what is the difference between LED, LCD, and Plasma TV’s? Quite simply, in goes in order of the TV’s ability to give you the best picture. Plasma is most expensive, LED is in the middle, and traditional LCD displays are at the bottom. At this point in time, your best bet would be to invest in an LED display since it is cheaper, but is almost equal to the Plasma quality. Also, with LED TV’s, you won’t have to worry about leaving a game console on or a DVD on pause, because while Plasma TV’s are able to have images “burned” into them, LED TV’s are not.
