How does a plasma screen work?

The secret to plasma technology lies between the two thin panels of mounted glass found within the screen. The panels are comprised of networks of pixels, tiny pockets of compressed gas. Each pixel contains three-subpixels made up of red, green, and blue phosphors -- the same color trio that account for the variety of hues found on all cathode-ray tube (CRT) devices, such as conventional televisions and computer monitors.

But what makes plasma TVs different is that each subpixel is individually controlled by "advanced electronics" to produce over 16 million colors. When an electrical current is applied to a pixel, the gas reacts to form plasma, which in turn produces UV light. The light reacts with the colored phosphors and magically enhances the flat screen to produce higher-contrast ratios and a better, more realistic picture. Because all the pixels emit light at the same time, the viewer never sees a flickering screen.

Unlike with CRT screens, there's no back lighting or electron beam, so the resulting images are consistently richer, sharper, and brighter. All this from a TV that ranges from 3 to 6.5 inches thick! Aside from a offering a host of other benefits, like longer viewing life and universal display capability, plasma screens are lightweight and versatile.

I think a plasma screen is a good clearing screen.I don't know its how to work but i believe it can't work durable in the hot environment.The hot can make it easier loss then LCD screen.I heard about this.I don't sure it is true story or not.In my country plasma accessories are expensive than LCD too.
