Title: Yasuhiro Shima: Innovator in Liquid Crystal Display Technology
Introduction
Yasuhiro Shima is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of liquid crystal display (LCD) technology. With a total of 4 patents to his name, Shima's work has advanced the capabilities and functionalities of LCD devices.
Latest Patents
One of Shima's latest patents involves a liquid crystal display device that features an array substrate and a color filter substrate. This device includes a liquid crystal layer positioned between the substrates, a backlight unit, and a controller. The controller is responsible for managing the application timing of a driving voltage to the pixel electrodes, as well as the light emission timing of the backlight unit. The design of the pixels is elongated in a lateral direction, with identical colors arranged laterally and different colors arranged vertically. Notably, neighboring pixels exhibit line-symmetry with respect to a center line, allowing liquid crystal molecules to tilt in a coordinated manner when voltage is applied.
Another patent focuses on a liquid crystal display device where the pixels have a polygonal shape that is elongated in the longitudinal direction. Each pixel is divided by a center line and is line-symmetric. The pixel electrodes and common electrodes are also divided line-symmetrically. This innovative design includes streaks on the surfaces of the pixel electrodes and a film that imparts a pretilt angle to the liquid crystal molecules, enhancing their performance.
