Title: Takaaki Kuroki: Innovator in Organic Electroluminescence
Introduction
Takaaki Kuroki is a prominent inventor based in Hachioji, Japan. He has made significant contributions to the field of organic electroluminescence, holding a total of 17 patents. His work focuses on enhancing the efficiency and durability of organic light-emitting devices.
Latest Patents
One of Kuroki's latest patents is for a transparent organic electroluminescence element. The objective of this invention is to provide a transparent organic electroluminescence element with excellent durability and a low-resistance transparent lead-out electrode. This design ensures that there is no uncomfortable feeling in the visibility of the entire element. The transparent organic electroluminescence element includes an organic electroluminescence portion and a lead-out electrode portion, allowing for two-sided light emission. The total light transmittance of the lead-out electrode portion in the visible light range is maintained between 90% to 110% compared to the organic electroluminescence element portion during non-light emission.
Another significant patent involves a light extraction substrate and methods for manufacturing both the substrate and the organic electroluminescent element. This invention aims to achieve both light extraction efficiency and preservability. A crucial step in the manufacturing process involves reducing the in-membrane water content to less than 1.0×10/mg before forming a cap layer. This low water content is maintained until the cap layer is formed through a dry process.
