Plasma display televisions, also known as plasma display panels or PDPs according to industry jargon, use the process of electrochemical to produce vivid pictures. The technology makes plasma televisions to offer the highest display quality available today. Plasma TVs use a display process that is quite different from conventional cathode ray tube (CRT) or Liquid crystal display (LCD) technologies.
Plasma TV sets are made out of a plasma layer that sits between two glass panes. The plasma itself is actually ionized gas. The plasma layer is a mixed solution of noble elements of gasses such as radon, xenon, krypton, argon, neon and helium. When electricity is charged through this plasma mixture, it engages phosphorescent elements in the plasma layer making them to emit light.
The layer of plasma is distributed into numerous small cells of chemicals. Each of these cells can be controlled to display a specific color. The outcome makes each cell acquire a desired color to display the preferred image. By electronically varying each cell’s color, the plasma is able to create an illusion of a picture in movement.
Many commercial plasma TV sets use argon, xenon, neon and in few cases nitrogen gasses in their layer of plasma. Electrodes expand from the central processing unit of the plasma display to each of the thousands of cells located in the plasma layer. The electrodes are coated with magnesium oxide to protect them from the chemical process that produces light in the display screen. When these electrodes are charges to reach different capacities, the plasma cells conduct the energy and emit light on the screen.
To produce different colors, each of the cells in the plasma layers has three subpixels: green phosphor pixel, red phosphor pixel and blue phosphor pixel. Each of these subpixels can be activated at any level of intensity. The outcome of this activation results in blending the three pixels together to get a full color in each cell. Each of these cells can show billions or varying color combinations and can be changes thousands of times in a second.
Plasma sets offer many advantages when compared to other TV displays. One of them is their capability to represent billions of color combinations. It allows accurate reproduction of the original picture that is a number of times better than LCD screens. The plasma display color process also enables the TV to achieve a better contrast ratio with deeper blacks and brighter whites.
Plasma TV allows the viewer to view the picture from different angles without compromising the picture clarity and color accuracy. The feature makes plasma TV sets perfect for industrial displays like in a sports field or a movie event.
Plasma TV’s also feature a quicker response time which means each of the cells in the plasma layers can be changes to another color quickly. It eliminates motion blur and artifacting in case of an object moving quickly on the screen.
Market segment and display size
Another aspect to consider in the application of plasma TV sets is their display size. Many plasma TV sets are up to or over 40 inches (when the screen is measured diagonally). Many brands offer plasma TV sets of varying sizes in the market.
