Eventually nearly everything has to be replaced and televisions are one of those things. If your old television just is not producing the quality picture that you want, it may be time to consider purchasing one of those new LED (light emitting diode) TVs. Buying a new TV will also allow you to give up that bothersome converter box since all new televisions are HD and digital ready.
Perhaps you are dauntless download size interested in some of the newer flat panel televisions. The first ones, Plasma and LCD televisions use fluorescent tubes as lighting for the screens. Since these tubes are on all the time, the sets had difficulty in producing dark black colors that make for a sharper image. Sometimes the light simply leaks around the diodes producing a dark gray at best. To the human eye, this causes the perception that the images are not clear or sharp.
Another problem with the LCD and Plasma TVs is that fluorescent light limits the number of colors that will show through the screen. This is due to the quality of fluorescent light and not the liquid crystal diodes, which can show unlimited colors.
This is where the new LED backlit TVs have the advantage. The LED back lighting can produce a much higher variety of colors than fluorescent lighting. Currently, there are two different ways to have LED lighting for a TV. One is to have LEDs that are placed along the edges of the screen and the other is to have them aligned behind the screen. Both of these setups offer advantages as well as disadvantages. One advantage of both set ups is that they both consume less electricity than the fluorescent lighting used with other televisions.
The edge lit LED TVs cost less money and can also be extremely thin. However, even though they are lit by the light emitting diodes, they cannot produce the sharp black colors of the back lit LED TV sets. They also have their lights on at all time just like the fluorescent sets.
The more costly sets are the back lit LED TVs. They are not as thin as the edge lit sets, however they do give a sharper black color. When a pixel needs to show the sharp black color, the lights behind that pixel are turned off. One problem with this technology is that since it is very expensive to set up the television to turn off one LED at a time, a compromise is made, and the lights are turned off in blocks. This may result in adjacent colors losing their brightness. However, these backlit LED TVs still produce superior sharpness compared to the other TVs discussed. In some situations, back lit screens produce extremely sharp colors. In others, however, the result may be a little blurred. Most consumers still feel that the best pictures are available with the backlit LED TVs.
This LED technology does come at a higher price than the older television sets. Before making a purchase, you would be well advised to take some time viewing all three types of sets. Because of differences in our eyes, one type may actually be clearer than another to you. Do not forget to check prices online. Often you are able to save quite a bit of money by comparing prices and making the purchase online.
