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.

In this case, only four of the eight on the board are used to control red, white, blue, and green cold cathode tubes. The video after the break shows the device randomly rotating through different ...

Some CT tubes are grid controlled for pulsed radiations to reduce the radiation dose. Field emission X-ray tubes (also called cold cathode tubes) In this style, in place of electron emission by ...

Georgia Tech researchers developed a new iron chloride cathode that could slash lithium-ion battery costs and revolutionize ...

The cathode tube was a prime example. By switching on some voltage, scientists could make fluorescent streams of electricity travel from the bottom part of a glass tube to the top -- but no one ...

While perhaps not exploding in popularity on the same level as the vinyl resurgence, the CRT gaming community is growing ...

A multi-institutional research team led by Georgia Tech ‘s Hailong Chen has developed a new, low-cost cathode that could ...

We’ll start with the CRT TV – also known as the tube TV, because CRT stands for cathode-ray tube. This is what started it all, and we were all pretty happy with it for, oh, a little over 65 years.

Cathodes emit electrons in sputtering systems, cathode ray tubes, and other vacuum tube systems ... cathodes used for field emission in vacuum tubes are called cold cathodes, whereas cathodes used as ...

With more and more manufacturers moving away from CRT (cathode ray tube) monitors in favor of newer ... Said light source ...

No matter your budget or how large a screen you want, here's what to look for when shopping for a television, along with the best TVs we've tested. I’ve been PCMag’s home entertainment expert ...

Sturdy and reliable, the cold-cathode displays found their way into ... the foundation of the Space Race sported the venerable tubes. But time marches on, and a display that requires high voltage ...
