Title: The Innovative Contributions of Koji Yoshioka
Introduction
Koji Yoshioka is a prominent inventor based in Kawasaki, Japan. He has made significant contributions to the field of display technology, holding a total of 5 patents. His work focuses on enhancing the functionality and efficiency of display devices, particularly in the realm of liquid crystal technology.
Latest Patents
One of Yoshioka's latest patents is a display device featuring a diffraction grating. This innovative device allows for color separation by enabling diffracted light of different orders to emerge, creating a vivid display. The design incorporates an array of micro-lenses arranged on a liquid crystal panel, which consists of multiple picture elements. Each picture element contains color display dots arranged in a vertical relationship according to the wavelength of light. This arrangement ensures that a green light component of the diffracted light is incident normal to the liquid crystal panel, while the zeroth order diffracted light passes through at a greater angle.
Another notable patent is for a liquid crystal display device and its production process. In this invention, a capacitor electrode is formed simultaneously with drain bus lines, establishing an electrical connection to two TFTs through a contact hole. An interlayer insulating film is then applied, along with a black matrix of light-blocking metal film, which collectively forms a capacitor. This innovative approach enhances the performance and reliability of liquid crystal displays.
