PLASMA SCREEN
A Plasma TV Display uses hundreds-of-thousands of miniature, embedded cells to produce a picture. Each cell equals one pixel, (picture element) and has three sub-cells. The three sub-cells are filled with a plasma gas which will 'glow' red, blue, or green (depending on the phosphor coating) when charged electrically. Light from the three "RGB" sub-cells combines to form a one colored pixel on the screen. Development of Plasma Display Technology is ongoing; with specific areas of concern remaining. Plasma Displays use phosphor coated screens, placing them at high risk of screen 'burn-in'. Plasma displays are not able to reproduce the color black; various shades of gray are the best that can be achieved - this can negatively affect picture quality. The plasma pixel-cells deteriorate over time causing the picture quality to diminish (fade).
