Title: Innovations by Yong-geol Kweon
Introduction
Yong-geol Kweon is a prominent inventor based in Seoul, South Korea. He has made significant contributions to the field of electron devices, particularly in the development of cathode ray tubes. With a total of five patents to his name, Kweon's work has greatly influenced the quality and performance of electronic displays.
Latest Patents
One of Kweon's latest patents is an "Electrode structure for an electron gun for a cathode ray tube." This invention includes common large-aperture electron beam passing holes designed to expand the electric field. The structure features three independent small-aperture electron beam passing holes, which help reduce the influence of spherical aberration on the electron beam, thereby improving the picture quality on the screen.
Another notable patent is the "Electron gun for a color cathode ray tube." This design incorporates parallel vertical blades extending toward the cathodes at both edges of each electron beam passing hole. The addition of horizontal blades at the edges of the electron beam passing holes enhances focusing characteristics and reduces astigmatism due to deflection aberration.
