Latest Patents
One of her latest patents is a liquid crystal display device that boasts high light utilization efficiency. This innovative device achieves a high light utilization efficiency and sufficient supplementary capacitance without compromising the aperture rate of pixels, thus enabling higher resolution displays. The design incorporates a silicon nitride film that serves as a transparent insulating film under the pixel electrode. Additionally, a common electrode made of ITO is connected to a potential common to an opposite electrode, forming a supplementary capacitance that enhances the display's performance.
Another notable patent involves a liquid crystal panel featuring tilted liquid crystal molecules. This panel is constructed by sealing a liquid crystal layer, made of a material with negative dielectric anisotropy, between an opposing substrate and a pixel substrate. The liquid crystal molecules are oriented at an angle between 3° to 10° with respect to the normal direction of the substrates. This configuration suppresses the occurrence of reverse tilt regions, thereby increasing the effective reflectance of the pixels and improving overall display quality.
