Title: Innovations of Tadao Ohoka in Liquid Crystal Display Technology

Introduction

Tadao Ohoka, an innovative inventor based in Aichi-gun, Japan, has made a significant contribution to display technology. His focused work in the realm of liquid crystal displays (LCDs) has led to the development of a unique patent that enhances the quality of color images in projection systems.

Latest Patents

Tadao Ohoka holds a patent for a color liquid crystal display that employs three dichroic mirrors reflecting white light from a light source. This inventive system divides the light into three beams of primary colors - red, green, and blue - through a dichroic mirror. The light beams pass through a micro-lens array before being modulated in a liquid crystal panel located beneath. The driver circuit supplies color signals, which adjusts the light beams effectively. The implementation of a schlieren diaphragm filters out scattered light, ensuring that only well-defined, modulated light enters into the projection lens. This process results in a clear and vibrant color image on the display screen, eliminating blurriness among the primary colors and utilizing a single liquid crystal panel without the need for color filters.
