Title: Chang Hyo Lee: Innovator in Flexible Display Technology
Introduction
Chang Hyo Lee is a prominent inventor based in Seoul, South Korea. He has made significant contributions to the field of flexible display technology and magnetic oxide manufacturing. With a total of 2 patents, his work showcases innovative approaches to modern technological challenges.
Latest Patents
One of his latest patents is for a flexible display device. This device includes a base film, a display sheet formed over the base film, and a structural pattern formed below the base film. The purpose of this structural pattern is to move a neutral plane with respect to the bending stress applied to the display sheet to a layer with a relatively low rupture point. By forming these structural patterns, the bending stress applied to the layer can be minimized, enhancing the durability of the flexible display device.
Another notable patent is for a method of manufacturing half-metallic magnetic oxide and a plasma sputtering apparatus used in the same. This invention involves a conductor with at least one hole placed between a metal target and a substrate holder. This configuration improves the bonding of metal ions discharged from the metal target to oxygen ions. Additionally, a magnetic field with a coercive force larger than that of the thin film being formed is utilized, resulting in a magnetic oxide film with excellent properties. The apparatus is designed to supply high power to decompose oxygen and discharge metal ions with different electrovalences at a precise ratio, making it effective for low-temperature manufacturing of half-metallic oxides.
