Product Description

The life performance of a numerical display tube depends to a great extent on the length of time the discharge is maintained on a single cathode (ie. number). This is because in any gas-discharge device the cathode is subjected to constant ion bombardment which removes material from the cathode and deposits it elsewhere in the tube. This "sputtering" is unavoidable, but is limited by keeping the peak current as low as possible, consistent with visibility of the display.

If a display tube is kept with one cathode constantly glowing (ie. one number displayed all the time) then material is sputtered from that cathode. This only affects the glow of that cathode a little, but the sputtered material lands on the other cathodes and affects the current required to make them glow, and can lead to uneven illumination.
If the discharge is cycled between characters regularly, this gives a much improved life since each cathode, although receiving some sputtered material, is subjected to the cleansing action of bombardment.
