Does anyone on the net know how "jumbo" screen tv works like that used at
sporting coliseums, stadiums, etc.?   Such as:

1. What makes up the picture elements? e.g. incandescent, fluorescents, etc???
2. How are the pixels addressed? SCRs? Electronic crossbar switching? 
3. How much power does the monster draw?
4. What is the resolution?
5. Special technical problems like flicker, chroma correction, comb filtering,
   multiplexing, etc.?
6. Who are some of the manufacturers?
