Introduction

Hiroshi Koshina is a notable inventor based in Chigasaki, Japan. He has made significant contributions to the field of spacer forming technology, holding 2 patents that enhance the manufacturing processes in this area. His work is particularly relevant in the production of liquid crystal displays.

Latest Patents

Koshina's latest patents include a spacer forming method and a spacer forming apparatus. The spacer forming method provides a technique for securely forming spacers in a predetermined region on a substrate. This method involves jetting ink containing granular spacers onto a crossing portion of a black matrix in a lattice shape. The process results in the formation of red pixel R, green pixel G, and blue pixel B in the openings of the lattice. The ink jetting method allows plural drops of ink to be jetted onto each spacer forming position on one of the opposite substrates, ensuring a constant gap for liquid crystal filling. His second patent focuses on a head module, printing apparatus, and printing method that stabilizes the discharge of spacer dispersed liquid through an ejection hole, preventing the settling of spacer particles.
