A cold cathode is a cathode in a gas-filled electron tube that is not heated by a filament. The voltage potential within the tube is sufficient to ionize the gas and cause the current to flow.

Finally, cold cathode lights can be used for much more than illuminating the inside of your computer or making your whip look like it can hover. [James] discovered if he varied the voltage going ...

The subject of this tutorial, the Hitachi S-4700 FE-SEM, utilizes a cold cathode field emitter composed of a single crystal of tungsten etched to a fine point. In scanning electron microscopy, ...

CCFL controllers provide control functions for the direct-drive inverters that are used to operate cold cathode fluorescent lamps (CCFL). A CCFL consists of a phosphor-coated glass cylinder with ...

STRL is constructing a prototype display using graphite nanofiber (GNF) as its cold cathode material. GNF is a nanometer *1 scale fiber material composed of carbon. Because it easily emits ...

Sturdy and reliable, the cold-cathode displays found their way into everything from scientific instruments to test equipment, and even some of the earliest computers and the equipment that formed ...
