wha's different for plasma and LCD TV?

Answer 1

zdotb is dead wrong. Plasmas have no light bulb, fluorescent or otherwise.

The difference is the technology used to create the picture.

Plasma uses gas trapped in glass. When current is applied, the gas lights up. LCD uses a bright backlight and filters that light through an LCD screen that allows the light to pass through or not. This is all a very simple description, but that's the essence.

In practical terms. Each has it's own advantages and disadvantages. Plasma is cheaper in large sizes, heavier, a bit dimmer, displays low light levels better, shows glare more, and has a tougher screen.

LCD is more expensive in larger sizes, lighter, brighter, displays low light levels worse (different shades of black all look black, and not truly black), show glare less, and the screen is more subject to damage.

Answer 2

plasma tv is based on a flourescent light bulb. good for larger sizes...like 50" and up. They suffer from burn-in, however (so watch out for video games, etc), and heat generation. better color saturation though. shoorter life time

LCD = liquid crystal display. best for under 50". brighter image than plasma. no burn in but individal pixels can die but rarely happens, dosent generate heat. longer life time.

i go lcd :P
