3. A This sheet shows some important points for handling and driving VFDs When a VFD is driven dynamically flickering may occur as a result of driving frequency This phenomenon can be resolved by changing the driving frequency When designing please note the following 1 The driving frequency is foo low When the display and the observer are not moving flickering can occur when the driving frequency is below 50 Hz If the display and or the observer is moving fickering can occur even if the driving freduency is above 50 Hz 2 Inferference between filament frequency and grid scanning frequency The filament is used as a cathode When the cathode potential is changed by the AC power supply voltage of th

10. Ef AC VFD DC DC VFD VV AC filament drive is the most popular driving method for the VFD Since the filament potential cathode potential has some amplitude the proper cut off bias voltage has to be applied to make the minimum filament potential higher than the anode and grid off voltage Generally a zener diode is used to set the cut off bias voltade It is recommended to ground center tap of the fllament If one end of the flament is connect
11. 1 2 For static drive generally there is one grid that is individually pinned out All anode segments must also individually be pinned out The grid is always supplied a posritive DC voltage and each anode is supplied a positive or negative voltage depending on it s selected or non selected status Each anode reduireS an Individual driver Dort for this driving method low voltage drive and high Iuminance can be achieved with this driving method The timing circuit which is reduired for dynamic drive is not needed For dynamlic drive there is one Individually Dinned out grid for each digit Corresponding anode segments are internally connected and Dinned out With dynamic drive a large number of digits does not significantly Increase the number of leads In order to be luminate a desired segment its on time is synchronized with its grid scanning Relatively higher voltage is reduired for dynamic drive than static drive When the duty cycle is 1 2 it is called duplex drive ON Anode Grid ON Eb Ec 2 el 3 Filament AC driving circuit
12. VFD VFD The color of light can be changed through the optical filter Some examples are shown below A Changing the Color The color green IS high Iuminous and has a wide spectrum It gets appropriate color from blue to red combined with various optical filter Pink filter color is almost wine red can turn the color to white The VariouS COlors of phosphor have been developed Used red or blue with main color green the optical filter of color close to red is difficult to transmit the blue light The blue light is hard to be seen because of the characteristic of the filter B Improvement of Color Durity By using same color filter as luminous light make the color more vivid Holder 1 2 3 4 Datum line
