35.1: Invited Paper: Very Sensitive Measurement Method of Plasma‐Display Exoemission

The very low exoemission currents are easily measured using an ultra high impedance amplifier which detects the integrated exoemission charge collected by a capacitance. The large discharge and displacement currents initiated by the changing sustain waveform, which could overload and saturate the sensitive amplifier, are shorted by a very low impedance switch.
