Better display
Liquid crystal displays (LCDs) are now used the worldover. But they still have not been able to compete with the old-faithful cathode ray tubes (CRTs), which are used to display high-quality images in television monitors. Now, scientists at Samsung, Korea, have produced a display that promises to use the quality of CRT images in a flat panel display. This is achieved by using carbon nanotubes as the source of electrons. The display is 11.43 cm in size and is fabricated by using single-wall carbon nanotubes. This could prove to be just what is needed to get LCD displays, of the kind used in laptop computers, to be as good as that of larger bulkier monitors ( Applied Physics Letters , Vol 75, No 20).
