Title: Yasuhiro Daiku: Innovator in Display Technology

Introduction

Yasuhiro Daiku is a prominent inventor based in Iruma, Japan, known for his significant contributions to display technology. With a total of 18 patents to his name, Daiku has made remarkable advancements in the field of liquid crystal displays and surface light sources.

Latest Patents

Among his latest innovations, Daiku has developed a surface light source capable of changing the range of spread angle of exit light. This surface light source includes first and second light sources that emit light, along with an optical deflection element. The optical deflection element modifies the light emitted from the first light source into first illumination light, which has a maximum exit light intensity in a direction parallel to the normal line of the surface light source. It also allows for high directivity in that direction. Additionally, the second light source emits light that is changed into second illumination light, which has a wider spread angle range and exits in an oblique direction. Furthermore, Daiku has created a liquid crystal display apparatus that incorporates a view angle limiting device, enhancing the viewing experience by controlling the angle at which the display can be viewed.
