Experiment study of forming and activation of conductive film of the surface conduction electron emitter display

Abstract

The forming and activation of the conductive films are studied experimentally. The power supply, a peak-to-peak 30 V triangle profile voltage, is applied to three kinds of conductive films that contain 0.25%, 0.5%, and 1% of palladium respectively. In the experiments we contrasted the values of related parameter in different conditions, observed the luminous spots on the anode panel, dealt with and analyzed the related data, and compared the positions and the amount of the luminous spots. We have gotten the conclusion that there is a threshold value U th. The emission current I e will increase rapidly when the device voltage U f is greater than U th. And the emission current I e could be controlled by the device voltage U f. The positions of the luminous spots on the anode panel are related with the device voltage U f.
