  • Method for surface treating cold cathode
    Patent number: 8431181
    Abstract: A method for surface treating a cold cathode includes the following steps. A cold cathode is provided and the cold cathode includes a plurality of field emitters. A liquid glue is placed on a surface of the cold cathode. The liquid glue is cured to form solid glue on the surface of the cold cathode. The solid glue is removed to allow the plurality of field emitters to stand upright.
