Plasma Display

Post  admin on Fri 23 Jul 2010, 2:36 am

Plasma technology creates red, green and blue lights in every pixel, reducing the need for space. Charged electrodes sandwiched between two glass panels react with tiny pockets of inert noble gases. This gas changes to a state of plasma, resulting in the production of UV light, which in turn reacts with red, green and blue phosphor in each pixel to emit visible light. Plasma technology uses pixels that are all “lit’ at once. Having no electron beam, backlighting or light polarisation, the image is brighter and sharper, and perfect from edge to edge. Plasma displays are bright (1000 lux or higher) and have a wide color gamut.

Advantages of plasma display technology are that a large, very thin screen can be produced, and that the image is very bright and has a wide viewing angle. The viewing angle characteristics of plasma displays and flat-face CRTs are essentially the same, topping all LCD displays, which have a reduced viewing angle in at least one direction. Plasma TVs also do not exhibit an image blur common in many LCD TVs. Plasma screens are not affected by magnetic fields and are free from any magnetic interference. They are generally flatscreen and light. The display unit can be located close to loudspeakers without the fear of any screen distortion generally caused by magnetic forces. Plasma technology, however, does have its limitations. Plasma displays generate heat and with the limitations of current technology have a lifespan of less than 30,000 hours.
