Integrated circuit system for operating display panels

摘要

The disclosure is of a system for driving gas-filled segment-type display panels including a plurality of groups of cathode electrodes, each having an anode electrode. The circuit includes means for holding the anodes at a relatively low potential for a short period of time after drive signals are applied thereto and to selected cathode electrodes. During this period of time, current flow charges a capacitor and raises the potential of the anodes to a potential at which ionization and cathode glow can occur. The circuit includes transistors utilized as resistors to hold off cathodes which are not intended to glow.
