Texas company demos carbon nanotube TV

In conventional CRT TVs, an electron gun fires electrons at a phosphor-coated glass divided into pinpoints to create images. The electrons, however, need to disperse in a large vacuum, which is why TV tubes are so large and bulky.

In so-called field emission display (FED) TVs, electrons get filtered into an array of thousands of tips only a few nanometers wide, which then deliver electrons to illuminate the screen. As a result, these TVs can be thin, like LCDs or plasmas.

Another advantage comes in cost. The tips, whether nanotubes or diamonds or some other material, in a FED are printed onto the display glass. By contrast, LCD panels and plasma screens require more ornate manufacturing processes. Decades of LCD know-how combined with the economics of electronics manufacturing mean that FED TVs won't likely challenge LCDs in the mass market. Yaniv, however, says FEDs' advantages will shine in large screens.

Thanks for the ping. You've been busy...(nice list)

Thanks, and you're welcome, all.
