1. hey i wonder the same thing
2. There is none HD is a feature There is a difference between plasma and LCD. Plasma has a better picture (slightly) but gives off heat like the old CRT TV's where LCD doesn't. HD ready means you don't have to buy an additional component, it's built into the TV I'm no expert, still learning too, good luck, recommend reading consumers report
3. i have no clue tell me whin u find out
4. There the Same thing. New TV's come in 3 types, LCD, DLP Projection, and PLASMA. Plasma: Plasma is a flat, lightweight surface covered with millions of tiny glass bubbles. Each bubble contains a gas-like substance, the plasma, and has a phosphor coating. Think of the bubbles as the pixels. Now, think of each pixel-bubble as having three sub-pixels - one red, one green, one blue. When it is time to display an image signal (RGB or video), a digitally controlled electric current flows through the flat screen, causing the plasma inside designated bubbles to give off ultraviolet rays. This light in turn causes the phosphor coatings to glow the appropriate color. Millions of RGB bubbles glow and dim to make a rich, vivid image on your plasma TV. LCD: What Is LCD Technology? Like popular LCD monitors you commonly see used with computers, LCD TVs have a slim design and a flat viewing surface, but have been fine tuned for video display. Recent advances in flat panel LCD technology now allow for larger screens, wider viewing angles, and higher-quality video images. LCD TVs are also competition for trendy-but-heavy, plasma display technology. They are several times lighter than comparably sized plasmas, and are far more durable. How do LCD TV's work? Two sheets of polarized transparent material, one with a special polymer coating that holds liquid crystals, are adhered together. Electric current is passed through individual crystals, which interpret the information from the broadcast signal to allow or disallow light through them to create an image. The crystals themselves do not produce light, so the technology is "non-emissive" and therefore does not give off radiation like an older television does. Fluorescent tubes housed behind the transparent material illuminate the image. They require less power to operate than CRT and plasma televisions which require powering hundreds of electrodes to stimulate the phosphorous. LCD TVs At-A-Glance: Use non-emissive technology; do not emit radiation. Use fluorescent tubes which require less power to operate. Use non-emissive technology; do not emit radiation. and of course we all know how projection works.
5. A plasma TV is the most popular and prevalant version of a flat panel televison, meaning the tv is very thin. HD, however just means a TV that is capable of showing about twice the number of lines as a traditional TV. This means you have a much better picture with much more detail. Most new plasma's, if not all, have HD built into them, but you still need to check to make sure!
6. Plasma refers to the display mechanism for a TV, as in cathode ray tube (CRT), liquid crystal display (LCD), or digital light projection (DLP). High-definition, on the other hand, refers to a standard resolution and frame rate designated as being HDTV. Therefore, a plasma television can meet the HDTV standard or it might not, and the same goes for a CRT, LCD or DLP set.
7. plasma is not the best if you are looking for a tv and hi def is a feature avaliable on most sets. I you are purchasing a tv the best right now would be a dlp but if you want you could wait a few years(1-3) for a oled to come out which is a organic light emiting diode. the oled's will be paper thin and could roll up like a projection screen. they have great resolution and use little electricity.

9. Plasma is the technology and it refers to a gas which produces the image on a TV. High-definition means it has an imagage that is high-defintion (which, in most cases, is very good quality).
