Wondering what will render your juicy new flat-screen TV obsolete? New Scientist says it could be emerging quantum-dot technology, in which LED displays are made up of zillions of nanoscale semiconductors that confine electrons in three dimensions.
The quantum dots stimulate electrons to higher energy levels, meaning brighter displays, more vivid colors and better detail. And you can stamp 'em out with the help of an ink-jet printer, so production costs should be pretty reasonable.
