plasma screen technology

These screens have become very common in the last few years due to large screen size and very slim-line design. Plasma screens are an example of a fully digital display system. A plasma display panel (PDP) is essentially a series of gas-filled vacuum pockets between two layers of glass. Each cell is filled with a gas that allows it to glow red, green or blue when excited by an electrical signal or impulse. The three (Red, Green, Blue) cells next to each other, together form one pixel. Each cell is addressed by a central processor that controls the brightness of each cell individually. Because of this, if true black is required, a cell simply is not switched on, and thus deeps blacks can be achieved. Plasma panels can also be very big (as big as 2,6m) and thus it makes them the only flat panel technology for very large scale applications.
