Plasma Tvs: What To Consider Before Buying
Before you go to buy a plasma TV, it is helpful to know a little about plasma display technology in order to make the right decision
. Even though plasma screen televisions entered the market in 1999, the concept has been around for quite some time. It is the plasma technology that will allow you to fully enjoy the various digital video sources such as the HDTV, DTV, computer video, digital satellite broadcasts as well as DVD video. The main benefit of using plasma screen televisions is that you are able to enjoy higher image resolution than most of the conventional TVs. This is because they are able to display full digital signals in a wide range, and thus give superior picture quality.
You would never see the scan lines that you tend to see with conventional TVs. This is because the conventional TV sets make use of an electron beam, in order to scan the photo tube from top to bottom at frequent intervals. They need to light the phosphors in order to create the image, and this leads to visible scan lines. On the other hand, in the case of plasma screen televisions, each and every pixel has its own transistor code. Thus there will be a smooth and evenly lit image on the display surface.
The colour accuracy in the case of plasma screen televisions is truly exceptional. This is because major advances have been made in plasma technology, as well as digital TV processing. This is the reason why plasma screen televisions are able to display billions of colours, with very subtle gradations between the shades resulting in a real life display of image. In fact, the plasma screen televisions claim to provide the best colour display among all the flat panel TVs, that are available in the market today. Besides, constant upgrades are constantly being made in colour accuracy.
The plasma screen televisions have a wide screen aspect ratio of 16:9. This was made in order to match the natural view of the human eye. In fact this is the same dimension that is used in the theatres. This way you are able to watch movies just as the director intended. This 16:9 ratio is the chosen aspect for HDTV content, no matter whether it is broadcast through air, digital cable or even satellite TV. And in case you are watching from a computer or a TV program that has a standard dimension of 4:3, the plasma screen televisions are able to extend the image appropriately. The image may be displayed with bars on the sides, or the image may be extended appropriately in order to fit the screen. It all depends on the algorithms being used by the manufacturer.
The plasma screen televisions have a slim look along with a space saving design. This ensures that you may either hang it from the ceiling or on a wall. Besides, you can mount it on your table too. It has a perfectly flat screen with no curvature that ensures no distortion at the edges of your plasma screen televisions.
