With a total of 9 patents to his name, Kim's work has had a lasting impact on display technology.
Latest Patents
One of his latest patents is an innovative electron gun designed for color CRTs. This electron gun features a triode that emits, controls, and accelerates red, green, and blue (R, G, B) beams. It includes main lens forming electrodes that focus these beams onto a screen. The design incorporates first dynamic quadrupole lens forming electrodes that provide distinct vertical and horizontal focusing actions for the R, G, B beams. Additionally, second dynamic quadrupole lens forming electrodes enhance the focusing actions for the R and B side beams, ensuring that the G beam, as a center beam, receives different focusing actions. This arrangement significantly improves resolution.
Another notable patent by Kim is an electron gun for color CRTs that features main lens forming electrodes. In this design, the depth from the rim portion of the anode to the electrostatic field control electrode is greater than that from the rim portion of the cathode. This configuration allows for a weaker DQ lens action for the center beam compared to the outer electron beam portion. As a result, the spot diameter is reduced by enlarging the main lens diameter and correcting inconsistencies between the center and outer beams.
