Title: Isao Yoshida: Innovator in Display Technology
Introduction
Isao Yoshida is a prominent inventor based in Ibaraki, Japan. He has made significant contributions to the field of display technology, holding a total of 8 patents. His innovative work focuses on enhancing the performance and efficiency of light sources used in various applications.
Latest Patents
One of Yoshida's latest patents is for a surface-emission light source with uniform illumination. This invention provides an extended area uniform light source that ensures consistent luminance for displays and other applications. The technology utilizes a combination of a blue light-emitting electroluminescent layer and a highly stable inorganic photoluminescent color conversion layer. This combination allows for the tailoring of the color spectrum of the emitted light, making it suitable for both planar and curved surfaces. The invention encompasses not only the uniform light source but also displays that incorporate these light sources and methods for their production.
Another notable patent is for a barrier layer for thick film dielectric electroluminescent displays. This innovation introduces a novel sub-structure that includes a barrier layer positioned between a substrate and a thick film dielectric layer. The barrier layer is chemically inert and inhibits the diffusion of at least one chemical species, resulting in higher capacitance for the thick dielectric layer. This advancement leads to improved display luminance and reduces the likelihood of dielectric breakdown, allowing for the use of lower-cost substrates like glass.
