Title: The Innovations of Masumi Arai
Introduction
Masumi Arai is a notable inventor based in Okazaki, Japan. She has made significant contributions to the field of electroluminescent displays and transparent conductive films. With a total of five patents to her name, Arai's work showcases her innovative spirit and technical expertise.
Latest Patents
One of Arai's latest patents is for a thin-film electroluminescent display and the method of fabricating it. This invention effectively prevents dielectric breakdown between both electrodes. The design includes a first transparent electrode layer, a first dielectric layer, a luminescent layer, a second dielectric layer, and a second transparent electrode layer, all laminated on a glass substrate to form a light-emitting element. A second light-emitting element is created in a similar manner. By applying a voltage between the electrode layers, the luminescent layers emit light, displaying desired characters. The corners of the electrodes are rounded to prevent electric field concentration, enhancing the display's reliability.
Another significant patent involves a method of making a zinc-based transparent conductive film. This film contains zinc oxide with gallium or indium, achieving a resistivity of not more than 10^-3 Ω.cm. The process involves evaporating a source of zinc oxide with specific percentages of gallium or indium oxide and depositing it onto a substrate after plasma activation.
