It's because the vibrant green light illuminating from the VFD shares similar spectrum as one of the three color-sensing cone cells.

Display Response Time Comparison


[ Top ]

How different is the display response?
VFD vs LCD Display Response Time
Learn More ►
Response time is more noticeable in below 0° conditions. VFD performs better while LCD freezes.

Vacuum Fluorescent Display (VFD)
How VFD Works
The VFD responds at the speed of light. VFD illuminates by the electron moving at the speed of light throught the grid to the anode in a vacuum environment.
Since VFD is vacuum inside, VFD is not effective by below 0° condition. Instead VFD performs better at below 0° condition.
Learn More ►

Liquid Crystal Display (LCD)
How LCD Works
The display response time for LCD is determined by the time it takes for the liquid crystal molecules to untwist and straighten out.
Unlike the VFD, LCD freezes at below 0° condition causing the LCD to perform very slow.
