Vacuum fluorescent display, referred to as VFD, is a low-energy electroluminescent display devices, the working principle and CRT similar. It has the incomparable advantage of liquid crystal display (LCD) in applications where there is a large variation in ambient brightness and no strict requirement for low power consumption, and is now widely used in audio-visual equipment, home electronics, automotive instruments, office equipment and instrumentation.
The structure of a VFD board is a typical vacuum triode structure, consisting of a cathode, a grid and an anode. In between the cathode and the anode there's a thin mesh of metal called the Grid that can be switched on or off, controlling the flow of electrons from the cathode to the anode. This VFD Grid Mesh is made of a thin metal plate with a thickness of 30 to 50μm, which is lithographed and made into a highly transparent fine lattice or tortoise-shaped metal mesh. When a positive voltage is applied to the grid, electrons emitted from the filament are accelerated and diffused toward the anode. When a negative voltage is applied to the grid, electron flow to the anode is cut off.
We Custom VFD Grid with drawings provided by customers. The raw material we use for Etched VFD Grid is SUS430 stainless steel. We are equipped with professional metal etching equipment and exposure development equipment. Our etched manufacturing capacity can achieve 0.05mm.
