Despite the flat screen and thin profile, plasma and lcd screen are very different. Plasma screens uses a matrix of tiny gas plasma cells charged by precise electrical voltages to create a picture. LCD screens are made up of liquid crystal pushed, acting as light filterm in the space between two glass plates. Images are created by varying the amount electrical charge applied to the crystals.
Both plasma and LCD sets produce excellent pictures, although many home entertainment specialists and gamers still say CRTs produce the best overall images. In the flat screens galaxy, plasma screens have a slight edge over LCDs. This is because plasma screens can display blacks more accurately than LCDs can, which means better contrast and detail in dark-coloured television or movie scenes. The nature of LCD technology, where a backlight shines through the LCD layer, means it's hard for it to achieve true blacks because there's always some light leakage from between pixels.
