Title: Hiroaki Matsuyama: Pioneer in Liquid Crystal Technology
Introduction: Hiroaki Matsuyama, based in Tokyo, Japan, is a distinguished inventor known for his significant contributions to the field of liquid crystal display (LCD) technology. With an impressive portfolio of 27 patents, Matsuyama has been instrumental in advancing the functionality and manufacturing of LCDs.
Latest Patents: Among his latest innovations, Matsuyama has developed a groundbreaking liquid crystal display panel and related devices. The liquid crystal display panel he designed allows for image display by controlling the orientation of a liquid crystal mixture at each pixel. It features a first common electrode on the first substrate, a second common electrode with a designated opening on a second substrate, and a pixel electrode on the second substrate. This setup enables the liquid crystal mixture, which has positive dielectric anisotropy, to be sandwiched between the electrodes, allowing for changes in the orientation direction primarily parallel to the substrate as a function of the electric field generated.
Additionally, his patent related to a liquid crystal display and its manufacturing method highlights a wide viewing angle and ease of production. This design includes an upper and a lower substrate, with a liquid crystal material positioned between them. A conductive protrusion on the upper substrate, in alignment with a scanning or signal electrode line, ensures that it shares the same potential as the upper electrode. Furthermore, the pixel electrodes on the lower substrate are crafted to be smaller in area than the common electrode, providing enhanced efficiency in display functionality.
Career Highlights: Matsuyama's career has been marked by his tenure at notable organizations such as NEC Corporation and NEC LCD Technologies, Ltd. His work at these companies has significantly impacted the development of LCD technologies that are widely used today.
Collaborations: Throughout his career, Matsuyama has collaborated with other esteemed professionals in the field, including Yoshihiko Hirai and Masayoshi Suzuki. Their combined expertise has contributed to the successful development of innovative LCD solutions.
Conclusion: Hiroaki Matsuyama's contributions to liquid crystal technology through his numerous patents underscore his role as a leading inventor in this field. His innovative designs and collaborative efforts have paved the way for advancements in LCD manufacturing and functionality, ensuring that he remains a notable figure in the realm of technological innovation.
