Title: The Innovations of Isao Kamiyama: A Pioneer in Organic EL Display Technology

Introduction: Isao Kamiyama is a distinguished inventor based in Tokyo, Japan, known for his significant contributions to the field of organic electroluminescent (EL) display technology. With an impressive portfolio of eight patents, he has been instrumental in the development of cutting-edge display systems that promise to advance visual technologies in various applications.

Latest Patents: Among his latest innovations are three notable patents: the Method of Manufacturing an Organic EL Display Panel, the Organic EL Display Panel, and the Organic EL Display Device. The patent for the Method of Manufacturing an Organic EL Display Panel delineates a sophisticated process that incorporates several essential steps. It begins with preparing a substrate and forming pixel electrodes arranged in a matrix of rows and columns. Banks that extend in a column direction are created between the pixel electrodes in the row direction. Following this, a first light-emitting layer is formed by applying an ink containing a light-emitting material into a specified gap between these banks. A second layer is subsequently formed using a vapor deposition method, ensuring it is continuous above the first light-emitting layer and the pixel electrodes. This innovation also details the construction of a counter electrode that is positioned above the second light-emitting layer, with specific design considerations for the height of the banks. The Organic EL Display Device patent describes the architecture of a display area that includes multiple organic EL elements aligned appropriately, along with structures that facilitate its functionality, including an organic insulating film and grooves that enhance operational efficiency.
