Field emitter displays (FEDs) offer improved image quality and brightness, as well as lower power consumption, over conventional flat-panel displays that use liquid-crystal display (LCD) technology. FEDs are not new. In fact, the Spindt cathode, the basis for FED design, was developed more than 30 years ago (see box on next page). The difficulty of converting success in the laboratory into practical, large-sized FEDs that can be mass produced, however, has hampered efforts to bring these products to market. Such devices are finally ready to compete with active-matrix LCDs as the industry's technology of choice.
