Myslite
How long is the life time of VFD?
The life time of VFD for commercial/consumer use is 30,000 hours.  This
life time is defined as the time when the initial brightness is reduced to
half its brightness. However, after that time, the VFD will still be
useable for displaying graphics, characters, and other patterns required
to meet the end user requirements.
