Filament supporter for use in vacuum fluorescent display tubes and method for filament installation

摘要

A method for safe and tight installation of a filament using a supporter obviates the need for welding. The supporter has an upstanding member such as a wing formed on the top of upward extensions from its surface. The member is located on one side of a plate of the supporter and has a clamping groove to hold and fix the end of the filament. The filament also can be wound around a lower part of the member thereby fixing the filament without welding.
