Title: Innovations of Jae-Sang Ha
Introduction
Jae-Sang Ha is a prominent inventor based in Suwon-si, South Korea. He has made significant contributions to the field of electron emission technology, holding a total of 6 patents. His work focuses on enhancing the reliability and efficiency of electron emission devices.
Latest Patents
One of his latest patents is for an electron emission source and its method of fabrication. This invention includes a carbon-based material, a vehicle composed of a resin component and a solvent component, and at least one metal oxide with an average particle diameter ranging from 100 to 1,000 nm, selected from AlO, TiO, and SiO. The composition is sintered under an air atmosphere during the formation of the electron emission source, which remarkably reduces carbon deposits and degradation of Carbon Nano-Tubes (CNTs). As a result, the electron emission source formed using this composition exhibits a high current density, and the electron emission device utilizing this source shows enhanced reliability.
Another notable patent involves an electron emission device that features a sealing member in contact with electrodes. This invention addresses issues related to arc discharge and wire disconnection due to increased resistance at the contact points. The design includes an electron emission device with exposed upper surfaces of electrodes, a front panel made of phosphor material, and a sealing member that effectively seals the space between the device and the front panel.
