I found an interesting article, cited below, from Time magazine from 2009 about flatscreen TVs being developed in Japan that use less energy and are therefore cheaper to run, but still have really high quality in terms of picture resolution. Sony developed the Bravia VE5 that uses much less energy for the backlight than a conventional television and also has features like a motion sensor that turns off the screen if there is no motion detected and a light sensor that adjusts the screen brightness based on the light already in the room. Other “eco-tvs” are being developed all the time, but the Sony TV sounds like it may be a good bet.
Flat panel devices require things like indium and tin, which must be mined.
