Plasma display
VISHAY
DC converter is also included to develop the necessary panel voltage.
The display operates on the patented principle known as "glow transfer". The display has 201 cathode elements per
column, of which the first element in each column is a "reset" cathode. The remaining cathodes are connected in 5 phases
where every 5th cathode is connected. The columns are scanned from the bottom to top by pulsing the reset cathode low,
followed by sequentially pulsing each phase low until the top cathode is reached, at which time a new scan is started at the
reset cathode. The anodes are energized starting at the time the reset code is energized until the desired display height is
reached, at which time the anode is turned off for the balance of the scan time. The cathodes are refreshed at a 70 Hz rate
so the scan appears to be flicker free.
