VFD
VFD Overview
VFD ( Vacuum Fluorescent Display)
VFD (Vacuum Fluorescent Display) is display representing data based on the following routes; thermal electrons are created through the voltage supplied in the Filaments and excellerated Electrons from Grids could reach Anodes to collide with phosphors already patterned to illuminate for displayiing.
※ Illuminates when (+)voltage is supplied to the Anode (+), does not illum ninate when (-) voltage is supplied
VFD(Vacuum Fluorescent Display) was first developed in 1967 and began to be applied to electronic calculators, and became colorized by the help of the co-development of a Phosphor maker in 1980¡¯s. VFD is an element which emits light by itself; through electrons constantly released from the Filament -functioning as an electron gun of CRT- controlled by the Grids and Anodes to collide onto the phosphors of Anodes to illuminate.
VFD surely represents Multi-color, excellent visual recognition by means of a clear display with high brightness (self-luminous device), less eye fatigue compared to LED (soft light), wide viewing angle, operating at low voltage with low power consumption, easy application of parts, and it has such a high reliability that VFDs apply to various areas
