Abstract

ABSTRACT: This paper examines the electron emission characteristics of the MgO layer in the case of spraying the MgO crystal powders based on the two monitoring parameters such as the electric field strength and the panel temperature. In particular, in order to analyze the effects of the electric field strength on the electron emission characteristics of the MgO layer with MgO crystal powders, the variations in the wall voltage induced by the electron emission are measured relative to the electric field strength between the address-sustain electrodes during an address period under various panel temperature conditions ranging from −5 to 65°C. As a result, it is observed that the electron emission characteristics of the MgO layer with MgO crystal powder strongly depend on the electric field strength rather than the thermal effect of exo-electron emission, which is confirmed by the measurement result of the wall voltage variation relative to the electric field strength under the low panel temperature of −5°C.
