Difference between LCD, LED and plasma television

The plasma television technology is based loosely on the fluorescent light bulb; this bulb is connected in this type of television. The display itself consists of cells, these cells provide energy. Within each cell two glass panels are separated by a narrow gap in which neon-xenon gas is injected and sealed in plasma form during the manufacturing process and this is why it is called plasma TV. The gas is electrically charged at specific intervals when the Plasma set is in use, this charging takes place through the cells. The charged gas then strikes cherry, lime, and blue phosphors, thus creating television representations. Each group of red, green, and blue phosphors is called a pixel picture element.

Plasma technology eliminates need for the bulky picture tube and electron beam scanning of traditional box, because it still employs the burning of phosphors to generate an image, Plasma televisions still suffer from some of the drawbacks of traditional televisions, such as heat generation and screen-burn of static images.

LCD TV Overview

LCD small screens, on the other way, use a different technology see also question #1 for this same clarification. Principally, LCD panels are made of two layers of transparent material, these layers are having its own work, which are polarized, and are "glued" mutually. One of the layers is coated with a special polymer that holds the individual liquid sparklers. Current is then passed through individual gemstones, which allows the crystals to pass or block light to create similes. LCD crystals do not produce their own glows, so an external light source and many other resources, such as florescent bulb is needed for the image created by the LCD to become visible to the viewer.

Unlike standard CRT and Plasma televisions screen, since there are no phosphors that light up and about, less power is needed for operation and the light source in an LCD TV generates less heat than Plasma or traditional TV screens. Also, because of the nature of LCD skill, there is no radiation emitted from the screen itself.

Plasma  vs. LCD

The advantages of Plasma over LCD are:

1. Better contrast ratio and ability to render deeper blacks.

2. Better color accuracy and saturation.

3. Better motion tracking (little or no motion lag in fast moving images).

4. Wider side-to-side viewing angle.

The DISADVANTAGES of Plasma vs. LCD include:

1. Is not as bright as an LCD TV, better for use in a dimly-lit or darkened room.

2. The screen surface is more reflective than most LCD TVs. More susceptible to glare - screen surface reflects ambient light sources.

3. Plasma TVs are more susceptible to burn-in of static descriptions. Conversely, this problem has diminished greatly in recent years as a result of the incorporation "pixel orbiting" and related technologies.

4. Plasma TVs generate more heat and use more energy than LCD TVs screens, due to the need to light of phosphors to create the images.

5. Does not perform as well at higher altitudes.
