Title: Inventor Mitsuo Nakamura: Innovations in Display Technology

Introduction

Mitsuo Nakamura, an esteemed inventor based in Yokohama, Japan, has made significant contributions to the field of display technology. With a total of three patents to his name, his innovative work has advanced the performance and efficiency of color liquid crystal displays.

Latest Patents

Nakamura's most recent patents include breakthroughs such as the backlight for color liquid crystal, the color liquid crystal display device, and an electroluminescent (EL) element for the backlight of color liquid crystal devices. His design for the backlight features a light-emitting layer containing EL phosphor particles dispersed in a dielectric matrix. The structure includes a transparent electrode layer on the emitting side and a reflective insulating layer along with a rear electrode on the non-emitting side. Under operational conditions with a voltage of 100 Vrms and a frequency of 400 Hz, this EL element can emit white light with a brightness of 80 candelas per square meter or more while consuming power of 30 watts per square meter or less. This innovation allows for a color liquid crystal display that is not only power-efficient but also excels in display performance, particularly suited for portable information terminals.

Additionally, his patent on the package film for the EL panel outlines the specifics of producing a moisture-proof layer using PCTFE or PET film, characterized by specific surface irregularities. These features help absorb and disperse oscillations caused by the polarity inversion of an alternate voltage applied to the EL panel, ultimately reducing noise from the LCD cell surface.
