Title: Innovations of Su-chan Lee in Display Technology
Introduction
Su-chan Lee is a prominent inventor based in Suwon, South Korea, known for his contributions to display technology. He has been instrumental in developing advanced plasma display devices and electron tubes, holding two patents that showcase his innovative approach to engineering.
Latest Patents
One of Su-chan Lee's latest patents is for a plasma display device with a ferroelectric dielectric layer. This invention includes a plasma display panel that features front and rear substrates, anodes arranged in a stripe pattern, and a lower electrode that coats the entire facing surface of the rear substrate. The dielectric layer, which coats the lower electrode, is complemented by an upper electrode in a specific pattern, with partition walls creating distinct pixels. This design minimizes sputtering and reduces damage to the electrodes, thereby extending the product's lifespan. The ferroelectric material used in the lower electrode exhibits excellent resistance to discharge gas, allowing for a low initial discharge starting voltage due to the cathode's ability to provide sufficient electrons for discharge.
Another significant patent by Su-chan Lee is for a cathode designed for electron tubes. This cathode comprises a layer of electron-emitting substances that contain alkaline earth metal oxides, along with a lanthanum compound and a magnesium compound. The base metal primarily consists of nickel, with tungsten included to prevent embrittlement and ensure a continuous supply of barium in the electron-emitting substance. This innovation allows for full interchangeability with conventional oxide cathodes and offers a lifespan that is 15-30% longer.
