Nanotubes Generate Full-Color Displays

TECHNOLOGYTOKYO-- Liquid crystal displays are fast becoming ubiquitous, but they still can't compete with bulky cathode ray tubes (CRTs) for displaying high-quality images. Now, a team of Korean researchers at Samsung has produced a working display that promises to combine the quality of CRT images with the convenience of a flat panel by using carbon nanotubes as its source of electrons. Their work, published in the 15 November issue of Applied Physics Letters , gives Samsung a small lead in a heated race to commercialize the technology.
