Wat is the technical difference between LCD and Plasma?

Answer 1

Sort of simply: Plasma=the pictures are made up of individual pixels, behind each one of which is a tiny chamber filled with gas. At the front of each chamber are phosphors; at the rear an electrical source. This electrical source ionises the gas into generating ultraviolet light, which excites the phosphors into glowing with the correct colours.
LCD=the screens comprise panels of tiny light valves and regulators. A coloured filter sits in front of each valve (or cell) and a large, bright backlight behind. Each of these cells has its own control system which decides the amount, and polarity, of the light that goes through it and thus the part each cell plays in producing the final picture.

Plasma generally give better contrast - blacks will be blacker
LCD's can suffer 'smearing' - that is the amount of time measured in milliseconds it takes for a cell to go from active (black) to inactive (white) and back to black again.
Plasma's are still prone to screenburn so if you watch a lot of Sky channels the logo will burn
Plasma screens still rule when it comes to size. Generally if you want over 32inch then go for Plasma
LCD's are generally brighter

Hope this helps...

LCD (Liquid Crysal Display) uses a special liquid between transparent electrodes. When a voltage is applied to the electrodes, the liquid rotates the angle of polariztion of light passing through it. This can be used to block light transmission, making a dark area, or let light through making a light area. LCD requires a separate source of illumination. For more details see http://en.wikipedia.org/wiki/Liquid_Crystal_Display

Plasma is an ionized gas. In a plasma display, the gas is contained in small cells, and is ionized by application of a voltage across the cell. Ionized gases can emit UV radiation, which can cause phosphors to glow (this is how fluorescent lamps work). Plasma displays therefore produce their own light and are similar to CRTs in that respect. Again, for more details see http://en.wikipedia.org/wiki/Plasma_display

Answer 3

LCD= Liquid crystal display, Plasma= Gas filled.

Answer 4

LCD = Liquid Crystal Display

Plasma is a part of the blood :0

No seriously for proper definitions check out

To sum up:


++++ Pros of Plasma over LCD

Slim design (Wall mountable)
Larger than LCD screens

---- Cons of Plasama compared to LCD

Expensive, although cheaper than LCDs at larger sizes.

Is subject to screen burn-in, but modern panels have a manufacturer rated lifespan of 50,000 or more hours.

First 2000 hours is its brightest point. Every hour there after, the display gradually dims.

At higher elevations, usually 6000 ft or higher, they exhibit noticeable humming.

Answer 5

LCD means Liquid Crystal Display... it used almost the same technology as your computer screen. Plasma TVs I believe use gasses.
