I'm sure there is a good reason that there aren't any LED TV's out there but I'm wondering why that is. LED's are very cheap, respond instantly, last a very long time, they are bright, and they can be made very small. Why not make a TV in which each pixel is made of three LED lights (Red, Blue, Green)? It doesn't seem like rocket science to me. Those giant screens in sports stadiums and Times Square use LED's so why not apply that to a TV? Maybe I'm completely out of touch. Maybe this has already been done or is soon to be released. I have seen a Sony TV that uses LED's as a backlight but wouldn't it be cheaper to use LED's as the pixels? Does anyone know anything about it?
