Title: Hirofumi Kubota: Innovator in Organic Electroluminescence Technology
Introduction
Hirofumi Kubota is a prominent inventor based in Tsurugashima, Japan. He has made significant contributions to the field of organic electroluminescence, holding a total of 11 patents. His work has paved the way for advancements in display technology, particularly in the manufacturing of organic electroluminescent display panels.
Latest Patents
One of his latest patents is for an organic electroluminescence display panel and the method for manufacturing it. This innovative display panel includes one or more organic electroluminescent elements supported by a substrate. Each element features first and second display electrodes, along with one or more organic functional layers that are sandwiched between these electrodes. The functional layers include a light-emitting layer, which enhances the display's performance. The panel is designed with a high-molecular compound film that covers the organic electroluminescent elements and the surrounding substrate. Additionally, an inorganic barrier film is applied over the high-molecular compound film to protect the display.
Another significant patent involves the method for manufacturing the organic electroluminescence panel. This method includes forming a first electrode layer on a substrate, followed by a second electrode layer. A passivation layer is then created to cover the organic material layer and the second electrode layer. Finally, either electron beams or ultraviolet rays are radiated onto areas of the organic layer that are not part of the light-emitting portion.
