Technology -Plasma TV

Plasma TV is believed to be have a better picture quality, and a less-energy efficient and nowadays available in larger sizes. Plasma TV screens light themselves using gas cells that emit ultraviolet light. Plasma TV is minimum 1.2 inches, and the power consumption of plasma T.V displays receives high power, screen size is 32 inches and above, it’s a heavy weight.Plasma TV is thicker and energy is generally more. Plasma TVs create images using phosphors, tiny plasma containers placed between two sheets of glass. These emit ultraviolet light at colored spots of phosphor on the screen, to create the picture.

Plasma TV displays very bright, have a wide color gamut, and can be produced in fairly large sizes, up to 262 cm. They have a very low-luminance. “dark-room” black level, creating a black some find more desirable for watching movies, news, songs. Plasma displays u more as much power per square meter as a CRT or an AMLCD television. Power consumption will vary greatly depending on what is watched on it. Bright scenes will draw significantly more power than darker scenes. The Xenon and neon gas in a plasma television is contained in hundreds of thousands of tiny cells positioned between two plates of glass.

The ultraviolet photons emitted by the plasma excite these phosphors to give off colored light. The operation of each cell is thus comparable to that of a fluorescent lamp. Every pixel is made up of three separate sub pixel cells, each with different colored phosphors.

In Plasma TV used as as a silicon or germanium diodes, the electrons and holes recombine by a non-radiative transition which produces no optical emission, because these are indirect band gap materials.
