Why are the customer displays of the VFD series getting darker and darker?


The display of the VFD customer display screen is based on the inert gas filled in the glass screen, and the inert gas will gradually become effective after long time use, so the brightness of the content displayed by the VFD will become dark, which is normal. However, if it becomes dark after a few months of use, it means that the glass screen is leaking and needs to be returned to the factory for replacement.
