Title: Innovations of Masato Kemmochi: Pioneering Liquid Crystal Display Technology

Introduction

Masato Kemmochi, an accomplished inventor based in Saitama-ken, Japan, has made significant contributions to the field of liquid crystal display (LCD) technology. With a total of five patents to his name, his innovative designs focus on improving display quality and reliability, making him a key player in the industry.

Latest Patents

Kemmochi's latest inventions include a revolutionary reflection type liquid crystal display device and a display apparatus. The design features a front surface of the opposite electrode of an LCD panel that is formed in a curved shape. This unique configuration defines the relationship between the reflecting surface of the pixel electrode and the curved surface of the opposite substrate, ensuring that light reflected by the first face of the substrate exits in a different direction than light emitted after reflection by the pixel electrodes through the liquid crystal layer. This technological advancement allows for the elimination of undesired light on the front surface of the substrate, resulting in high-quality images free of dazzling effects and enhanced contrast ratios. Furthermore, in his display apparatus containing this innovative LCD, the incident surface to a dichroic prism is inclined and curved, effectively separating signal light from undesired reflected light on the prism’s surface. Such improvements lead to high-quality image displays with superior contrast ratios.

Another notable patent involves the array substrate and methods for manufacturing liquid crystal display devices. This technology focuses on developing inter-layer insulating films that are sufficiently thick to prevent breakage of conductive layers at contact holes, ensuring reliability. The process combines inorganic materials, such as silicon nitride or silicon oxide, with organic materials like acrylic resin. This innovation allows for a gentler slope of the contact hole walls, thereby reducing the risk of breakage in thin conductive layers measuring 100 nm or less.
