Danbooru の英語定義
An electronic device developed in the 1950's for displaying numerals or other information using glow discharge. They're a glass tube filled with a low-pressure gas, such as neon, and contains a wire-mesh anode and multiple cathodes shaped like numerals or symbols. Applying power to a specific cathode surrounds it with an orange glow discharge. The technology was superseded in the 1970's by light-emitting diodes (LED's), vacuum fluorescent displays (VFD's) and liquid-crystal displays (LCD's).
