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.
