Title: Masaki Obi: Innovator in Liquid Crystal Display Technology
Introduction
Masaki Obi is a prominent inventor based in Ageo, Japan, known for his significant contributions to liquid crystal display (LCD) technology. With a total of 5 patents to his name, Obi has made strides in enhancing the performance and efficiency of display elements.
Latest Patents
Obi's latest patents include innovative designs for liquid crystal display elements. One notable patent describes an electrode slit portion formed in a pixel electrode that crosses a slit, dividing a liquid crystal layer into multiple domains. This design incorporates a titanium oxide film that is exposed to the liquid crystal layer, which has a higher relative dielectric constant than the organic film at the electrode slit portions. This configuration allows for the setting of an electric field in each domain, ensuring that the angles between the director near the electrode slit and the transmission axes of polarizing plates are approximately 45°. This innovation effectively suppresses the decrease in transmittance caused by the director's falling direction, thereby securing both transmittance and contrast ratio while providing an excellent wide viewing angle range.
Another significant patent involves an operative reflection and absorption plate that features a substrate with a moth eye structure on its surface. This design enables the realization of both absorbing and reflecting statuses without the need for a polarizing plate, resulting in a display element that exhibits bright and high contrast.
