Latest Patents
Ohsawa's latest patents focus on advancements in liquid crystal display devices. One of his notable inventions includes a liquid crystal display device that features a liquid crystal cell with a twist-aligned liquid crystal layer at 90 degrees. This device is designed with first and second polarizing layers that sandwich the liquid crystal cell, ensuring optimal performance. The arrangement of the polarizing layers is such that their absorption axes are set parallel to directions that cross the aligning treatment directions of the substrates at 45 degrees. Additionally, viewing angle compensating plates are strategically placed between the polarizing layers and the liquid crystal cell. The total value of retardations in the thickness direction is defined as a product of the phase difference within a plane perpendicular to the substrate surfaces of the liquid crystal cell and the layer thickness. This innovative design aims to cancel out any retardation in the liquid crystal layer thickness direction when a saturation voltage is applied.
