Abstract

A severe problem in the operation of the AC gas panel display is the handling by the electronics of the high peak currents which are passed during discharge of the gas. Expensive electronic circuits are required to provide the necessary sustain voltage without a "notch" in the current. One method for minimizing this problem is to increase the thickness of the dielectric layer, which would decrease the cell capacitance. Thus, if the dielectric thickness were increased from a value of about 25 Mu m to 50 Mu m, the peak current would decrease by a factor of 2, which would give a significant cost reduction in the electronics.
