What is the difference between Plasma and LCD TVs?

Answer:
The difference between plasma and LCD television

is that plasma televisions use a neon-xenon gas plasma within the display, and LCD televisions use liquid crystals in the display.

The technical differences:
Plasma TV has thousands of individual cells built into a matrix in the display. Each cell consists of two glass plates, separated by a narrow space, which is filled with neon-xenon gas plasma. When the plasma is electrically charged at varying intervals, it excites the red, green and blue (RGB) phosphors which make up the pixels, creating a color image.

LCD TV has a polarized, bonded, two-layer display. One layer is coated with liquid crystal containing polymers. Varying electrical currents through the crystals causes them to either block light (from built in light source) or allow it to pass through, creating a color image.

Some advantages to Plasma TV are: rich colors, minimal image lag.
Some disadvantages are: power consumption, heat, fragility, weight.

Some advantages to LCD TV are: cool operating temperature, no image burn in, no screen radiation, lightweight.
Some disadvantages are: image lag, lower contrast, pixel burnouts.
