Title: Innovations of Yoshimitsu Ishikawa

Introduction

Yoshimitsu Ishikawa is a prominent inventor based in Tokyo, Japan. He holds a total of 11 patents, showcasing his significant contributions to the field of display technology. His innovative work has paved the way for advancements in liquid crystal displays and stereoscopic image technology.

Latest Patents

One of his latest patents involves a display that utilizes an electric field generated in a transverse or diagonal direction to drive liquid crystals. This design enables the allocation of a contact area for a conducting connection. A transparent electrode layer is formed on a surface of a counter substrate, which is opposite to the surface where the liquid crystals are disposed. The counter substrate is part of a liquid-crystal display panel. Additionally, an electrode layer is formed on the rear surface of a protective plate that faces the counter electrode. Conductive substances are strategically placed between the transparent electrode layer and the electrode layer to ensure a proper connection. A GND connecting part in the surrounding area of the protective plate connects the electrode layer to the casing, thereby linking it to the GND.

Another notable patent is for a stereoscopic image display apparatus and its drive method. This display panel features sub-pixel pairs arranged laterally at a predetermined pitch, with each sub-pixel displaying images for the right and left eyes respectively. A parallax-barrier shutter panel is included, which has sub apertures that switch between light-transmitting and light-blocking states. This is achieved by driving a liquid crystal layer held between two transparent substrates with transparent electrodes. The arrangement of the sub apertures is based on a reference parallax-barrier pitch, which is determined by a predetermined design observation distance and the pitch of the sub-pixel pairs.
