Flat Panel Televisions
Flat Panel Televisions create images using either LCD or plasma screen technology. Flat screens mean that flat-panel TVs maintain perfect image focus and geometry from top to bottom, side to side, and corner to corner.
Plasma Technology
Plasma Technology Display consists of two transparent glass panels with a thin layer of pixels (tiny fluorescent bulbs) sandwiched in between. The layers contain somewhere between 800,000 and 2,000,000 tiny fluorescent bulbs, — the pixels. Each pixel is composed of three gas-filled cells. One each for the primary colors, red, green and blue. A grid of tiny electrodes applies an electric current to the individual cells, causing the gas to ionize. This ionized gas (plasma) emits high-frequency UV rays which stimulate the cells' phosphors, causing them to glow, which creates the television image.
LCD Technology (Liquid Crystal Display)
Liquid Crystal Display consists of two polarizing transparent panels with a liquid crystal solution sandwiched in between the two panels and a "backlight" behind the panels . An electric current passed through the liquid causes the crystals to align so that light cannot pass through them. Each crystal acts like a shutter, either allowing light to pass through or blocking the light. The pattern of transparent and dark crystals forms the television image.
