Display Response Time Comparison
[ Top ]
| How different is the display response? |
|---|
|
| Learn More ► |
| Response time is more noticeable in below 0° conditions. VFD performs better while LCD freezes. |
[ Top ]
| Vacuum Fluorescent Display (VFD) |
|---|
![]() |
| 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 ► |
[ Top ]
| Liquid Crystal Display (LCD) |
|---|
![]() |
| 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. |
