MANUFACTURING METHOD OF ELECTRIC FIELD EMISSION SOURCE AND ELECTRIC FIELD EMISSION SOURCE MANUFACTURED BY METHOD THEREOF

摘要

The present invention relates to a manufacturing method of an electric field emission source and an electric field emission source manufactured by the method thereof with an improved use life span, comprising: aligning step of aligning and arranging an electric film emission emitter material in a vertical direction; and coating step of forming a ZnO coating by a hydrothermal crystallization process on the surface of the emitter material. The present invention produces an effect of greatly improving the life span of an electric field emission source by forming a thin ZnO coating by a hydrothermal crystallization process. In addition, the hydrothermal crystallization process is a solution process which does not use a high temperature, and thus is low in manufacturing cost and suitable for mass production, and thus produces an effect of greatly lowering the manufacturing cost of an electric field emission source.;COPYRIGHT KIPO 2016
