brain1 writes "PhysOrg is reporting that Motorola has developed a 5" flat-screen prototype display that uses carbon nanotubes. The display appears to promise lower costs for a full 40" HDTV screen bringing the price down to $400. The technology uses standard color TV phosphors, has a response time equaling CRTs', all in a package 1/8" thick. The display characteristics meet or exceed CRTs', such as fast response time, wide viewing angle, and wide operation temperature. All these are areas that LCDs are weak in. Is this the breakthrough we needed to finally make HDTV and flat-panel computer displays *really* affordable?"
