Plasma TVs are a breakthrough in technology that freed the world from conventional television sets. The major advantage of the plasma TV is its high picture quality. Plasma TVs are also preferred because they are mountable, slim and lightweight and hence do not occupy much space.
The plasma TV is so called because of the technology that invented it. The crux of the Plasma Display panel involves two glass panels consisting of tiny cells filled with noble gas. On turning these cells into Plasma electrically, they excite green, blue and red phosphors to emit different colors of light. This technology can capture the movement of pictures on screen, quicker than any of its successors. This is a specific trait of plasma TVs.
Plasma televisions are often mistaken for LCDs. Though the plasma TV and the LCD (liquid crystal display may look alike, they are powered by entirely different technologies. The similarities between a plasma TV and an LCD TV are the slim structure, the flat display, and the technical specifications which affect the overall performance of the product.
What makes plasma TVs stand out is the wide-viewing angle which may not be satisfactory even among its successors. A higher contrast ratio and a greater color spectrum add to its credit.
The invention of different and superior formats of picture quality necessitated the demand for an advanced viewing mode. The signals such as HDTV (High Definition Television), SDTV (Standard Definition Television) and also signals such as XGA, SVGA and VGA required a screen that would transmit the details of a picture. This was achieved through plasma TVs since they delivered high picture quality output.
Despite the development in technology, plasma TVs have still not been overcome in certain areas such as their geometric distortion. They produce pictures that are geometrically perfect and hence exhibit zero distortion. A plasma panel has a smoothly even light output, thereby producing no dark spots or hot spots. The focus of a plasma TV is uniformly distributed. Hence there is no angle from which a view may be distorted. Plasma panels are not susceptible to magnetic fields.
What makes plasma television take the back seat in the industry is the fact that its disadvantages have been highly overcome by its successors (the LCD and the LED). Plasma TVs , despite their varied advantages, have some drawbacks which proved to be fatal to its future. Potential burn-ins, lower brightness, extreme fragility and shorter life are some of its unavoidable drawbacks.
Ever since the invention of LCD TVs, plasma TV has taken a backward step due to the competition between the two. LCD uses an energy efficient technology and overcomes the drawbacks of the plasma display. Therefore, the industry prefers LCDs now to the comparatively older plasma TVs. However, plasma display holds its ground where big picture screening is concerned, due to its incomparable picture quality.
