Title: Syoichi Hirota: Innovator in Liquid Crystal Display Technology
Introduction
Syoichi Hirota is a notable inventor based in Hitachi, Japan. He has made significant contributions to the field of liquid crystal display (LCD) technology. With a total of 2 patents, Hirota's work has advanced the functionality and efficiency of LCD devices.
Latest Patents
Hirota's latest patents include a liquid crystal display device featuring pole spacers formed over an optical shield film. This innovative method involves forming a metal film over a drive substrate and patterning it to create at least one pixel electrode and an optical shield film. The optical shield film is strategically placed outside the pixel electrode area, ensuring a width greater than that of each pixel electrode. Additionally, a resin is deposited over the patterned metal film, which is then patterned to form pole spacers and strip spacers. The strip spacer surrounds the pixel electrode area, providing structural integrity to the display.
Another significant patent by Hirota is a liquid crystal display device with an optical shield film. This invention aims to eliminate differences in cell gap within a liquid crystal panel, thereby preventing display irregularities. The design includes a first substrate with multiple pixel electrodes arranged in a matrix and a second substrate that opposes the first with a specified gap. A liquid crystal layer is sealed between these substrates, and pole-like spacers are incorporated to maintain the gap at a predefined value.
