Title: The Innovations of Masanori Ogino in Liquid Crystal Display Technologies

Introduction

Masanori Ogino, a prominent inventor based in Yokohama, Japan, has made significant contributions to the field of liquid crystal display (LCD) technologies. With a remarkable portfolio of 51 patents, Ogino's work demonstrates a commitment to advancing display technology and enhancing visual experiences.

Latest Patents

One of Ogino's latest patents focuses on a liquid crystal display unit. This innovative apparatus utilizes white light input directed through light-diffracting means, which consists of a structure that includes macro prisms combined with a lenticular structure. This unit is designed to harness diffraction gratings at a microscopic level. By modulating the height of the unit steps in the diffraction grating at regular intervals of arranged pixels, the device achieves a sophisticated decomposition of output diffracted light into the three primary colors. This technology addresses limitations found in prior pitch modulation type diffraction gratings, where red and blue light rays experienced convergence deviations of about 30%. With Ogino's arrangement, the enhanced design eliminates these deviations, delivering high light utilization efficiency for single plate type color liquid crystal display apparatuses.
