High Quality Content by WIKIPEDIA articles! A vacuum fluorescent display (VFD) is a display device used commonly on consumer-electronics equipment such as video cassette recorders, car radios, and microwave ovens. Unlike liquid crystal displays, a VFD emits a very bright light with high contrast and can support display elements of various colours. The technology is related to both the cathode ray tube and the nixie tube. The device consists of a hot cathode (filaments), anodes (phosphor) and grids encased in a glass envelope under a high vacuum condition.
