What is Cold cathode?
A '''cold cathode''' is a [[cathode]] (a type of electrode) that is not heated directly by a [[filament]] or element, although a cold cathode can heat up during use as a side effect of normal [[Electric current|current]] flow. The term cold cathode is often used to refer to cold cathode fluorescent lamps (CCFLs), which are often used where a long life is needed. Applications for cold cathode lamps include general lighting, [[backlight]]s for LCD [[television|TVs]] and [[computer monitor]]s, and artistic lighting such as computer case mods and automotive customization. {{Tech-stub}} [[Category:Electronics]] [[tl:Agapito Flores]]
