Tampilan plasma: Perbedaan antara revisi

Tampilan plasma diciptakan di [[Universitas Illinois]] oleh [[Donald L. Bitzer]] dan [[H. Gene Slottow]] pada 1964 untuk [[PLATOPLANO|Sistem Komputer PLATOPLANO]]. Panel monochrome orisinal (biasanya [[oranye]] atau [[hijau]]) menikmati penggunaan yang bertambah pada awal 1970-an karena tampilan ini kuat dan tidak membutuhkan sirkuit memori dan penyegaran. Namun diikuti oleh kurangnya penjualan yang dikarenakan perkembangan semikonduktor memori membuat tampilan [[CRT]] sangat murah pada akhir 1970-an. Dimulai dari [[dissertasi]] PhD [[Larry Weber]] dari Universitas Illinois pada 1975 yang berhasil membuat tampilan plasma berwarna, dan akhirnya berhasil mencapai tujuan tersebut pada 1995. Sekarang ini sangat terangnya dan sudut pandang lebar dari panel berwarna plamsa telah menyebabkan tampilan ini kembali mendapatkan kepopulerannya.

Plasma displays are bright (1000 [[lux|lx]] or higher for the module), have a wide color [[gamut]], and can be produced in fairly large sizes, up to 200 cm (80 inches) diagonally. They have a very high "dark-room" contrast, creating the "perfect black", desirable for watching movies. The display panel is only 6 cm (2 1/2 inches) thick, while the total thickness, including electronics, is less than 10 cm (4 inches). Plasma displays use as much [[Electric power|power]] per square meter as a [[Cathode ray tube|CRT]] or a [[AMLCD]] television; in 2004 the cost has come down to US$1900 or less for the popular 42-inch diagonal size, making it very attractive for home-theatre use. However, since the power consumption is proportional to the square of the diagonal size, the larger screen sizes can use considerable power—power—"as much as 700 watts of power, enough to make some critics worry about the environmental consequences if the displays are widely adopted."[http://www2.technologyreview.com/articles/04/11/mann1104.asp?p=2]. The lifetime of the latest generation of PDPs is estimated at 60,000 hours to half life when displaying video. Half life is the point where the picture has degraded to half of its original brightness and intensity, which is considered the end of the functional life of the display.

The xenon and neon gas in a plasma television is contained in hundreds of thousands of tiny cells positioned between two plates of glass. Long [[electrodes]] are also sandwiched between the glass plates, on both sides of the cells. The address electrodes sit behind the cells, along the rear glass plate. The transparent display electrodes, which are surrounded by an insulating dielectric material and covered by a magnesium oxide protective layer, are mounted above the cell, along the front glass plate.

To ionize the gas in a color panel, the plasma display's computer charges the electrodes that intersect at that cell thousands of times in a small fraction of a second, charging each cell in turn. When the intersecting electrodes are charged (with a voltage difference between them), an electric current flows through the gas in the cell. The current creates a rapid flow of charged particles, which stimulates the gas [[atom]]s to release [[ultraviolet]] photons.
