VFD Filters


A VFD display will wash out in direct sunlight. A filter provides better contrast and protection for the VFD. There are two main filter types: Circular and Regular polarized. Circular polarized types come in gray and are hard-coated providing the ultimate outdoor filter. The regular filters are a less expensive solution for an indoor VFD, but still can be used outdoors. However, they do not provide the same protection as the gray ones. All filters are available in the 2x20 and the 4x20 sizes.
