Title: Hitoshi Kondo: Innovator in Liquid Crystal Display Technology

Introduction

Hitoshi Kondo is a prominent inventor based in Machida, Japan. He has made significant contributions to the field of liquid crystal display (LCD) technology, holding a total of 9 patents. His innovative approaches have paved the way for advancements in display quality and efficiency.

Latest Patents

One of Kondo's latest patents is a method of driving an LCD that employs the combination of two voltages which change. This invention discloses a method of operating an active matrix liquid crystal display device that has a liquid crystal layer between a pair of substrates. It includes at least one active device for each picture element electrode on at least one of the substrates. The driving signal applied to a picture element electrode during one frame cycle is always on the side of a voltage with an identical polarity. This method is substantially free from scattering in the display, can be operated at a low driving voltage, and achieves high contrast.

Another notable patent is for a deposited multi-layer device with a plastic substrate. This device features an electronic element and a plastic substrate on which an inorganic substance thin film layer is simultaneously formed on both surfaces. Each of the electronic element, plastic substrate, and inorganic thin film has internal and thermal stress not equal to zero. This design prevents peeling, deformation, or curl of the substrate and degradation due to impurities such as acid, alkali, and water.
