  • Electron beam focusing electrode and electron gun using the same
    Patent number: 8912505
    Abstract: An electron beam focusing electrode and an electron gun using the same may include a plate having a polygonal through-hole; at least a projecting portion formed on at least one side of the through-hole. By using the electron beam focusing electrode, a spreading phenomenon of an electron beam having a rectangular cross section may be reduced. Further, the output of the electron gun may be increased, and electron beams may be easily focused.
    Type: Grant
    Filed: October 4, 2012
    Date of Patent: December 16, 2014
    Assignees: Samsung Electronics Co., Ltd., Seoul National University Industry Foundation
    Inventors: Chan Wook Baik, Anurag Srivastava, Jong Min Kim, Sun Il Kim, Young Mok Son, Gun Sik Park, Jin Kyu So
