ABSTRACT:
In a flat panel cathodoluminescent display utilizing a plurality of electron guns a single line cathode is used as the electron source for all guns. Changes in electron beam current resulting from vibration of the line cathode are compensated for by the application of voltages which are related to the current changes. The compensating voltages are applied through an impedance network which relates the voltages in accordance with the envelope of vibration so that the actual compensations at the individual guns are related to the actual current changes at the respective guns.
