Vfd Driver Chip
CIGVFD is the VFD with a driver IC mounted on it. In many cases, a conventional full dot matrix type or 5 7 dots type had difficulty to be designed because of too many lead terminals. By mounting the driver IC chip on VFD base plate, the leads needed to drive the VFD are only for power supply and signal.
It is a drastic reduction of external leads.
1. The small package which couldn t be realized so far, the VFD of the big capacity indication and high density can be realized.
2.Because wiring on the circuit board decrease, circuit board design becomes easy, and a development period can be shortened.
3.This VFD can reduce the cost of PWB.
4.The number of the lead terminal were drastically reduced to several connections to the PWB, which reduces the manufacturing complexity.
5. Since the VFD is constructed with driver IC,no external driver is necessary.
6.The VFDis a custom designproduct.When employing the VFD design,the peripheral devices can now be standardized.

4.1 Grid Scanning Frequency Refresh Frequency
When multiplexing, the selection of a slow grid scanning frequency may cause a flickering effect, which is a result of the optical beat generated by the on and off luminescent cycle and the image retention of the human eyes. As the anode and grid current is varied by the filament voltage level, you may observe flickering when the beat frequency between the AC filament or pulse and the grid scanning is 40Hz or less. Therefore we would suggest combinations as per Table 1.
Alternatively, high frequency scanning may cause problems because of insufficient pulse width for luminance against blanking time. If flickering is caused by this, avoid a scanning frequency between 250Hz and 500Hz.
