In a plasma screen, there are over sixteen million pixels making up the display. Each of those sixteen million are made up of three pixel colors of blue, red and green phosphors, which are evenly distributed across the screen. The entire screen which you view, or rather the picture you watch is made up of a combination of these three colors.
The plasma itself sits and operates between two thin glass panels. Millions of tiny images (made up of the greens, reds and blues) are made by the illumination of fluorescent lights put through them. And the plasma is made of a gas made up from electrically charged atoms and negatively charged particles. Then electricity is passed through it, which starts the ‘lighting' process, or what we see on-screen.
Plasma TV's are at the top end of the scale, when it comes to price compared to other types of flat screen. But is there an advantage we clearly see with a plasma TV, compared to LCD?
Because of the flat screen, there is no edge distortion which you sometimes get on normal or CRT TV's.
View movies made in widescreen or 16:9 format as they should be – in widescreen, not with half a picture cut off! And you know how annoying and frustrating that can be, when you get half the picture cut off or you can't see the subtitles at the bottom of the screen!
With a plasma, brightness of the display is uniform from one corner to the other. With conventional TV's you get bright and dark mixed colors, but you don't have this problem with a plasma display. All sixteen pixels are illuminated evenly.
A major problem with the old type televisions is the huge amount of space they take up in your living room, but this problem is non existent with a flat screen. Because of the slim design, plasma televisions give more options when it comes to mounting them. Be it eye level height, or up higher you can mount a plasma on the wall or it can sit on a normal TV stand.
Another thing which is great about plasmas is that magnetic fields do not interrupt the screen. Plasma displays work completely different from conventional televisions, which uses electron beams, which as you know can be affected greatly by magnetism.The advantages of a plasma can easily be seen here. So you know that sound system you wanted to plant right next to your TV set? With a plasma, you can have the speakers as close as you like without it affecting the picture.
