Latest Patents

One of his latest patents is for a liquid crystal display that features an SiO₂ flattening layer. This innovative display is designed to be simple in construction and low in cost while providing high-quality display performance. The design includes a color filter substrate, an opposing substrate, and a nematic liquid crystal charged between both substrates. The color filter substrate consists of a transparent substrate with a transparent electrode mounted on one surface. A color filter is electro-deposited on the transparent electrode, and a light-shielding film is formed in the clearances provided for the color filter. Additionally, an inorganic dielectric film is mounted on the surfaces of the color filter and the light-shielding film, enhancing the overall functionality of the display.

Another significant patent involves a method of manufacturing color filters. This method includes several steps, such as forming a plurality of transparent electrodes on a transparent board, stacking color filters of various colors, and using a high-energy beam to selectively remove the transparent electrodes and color filters. The process also involves coating a black resist onto the surface of the transparent board and exposing it to light, which allows for the formation of a light-shielding film around the color filter. This innovative approach improves processing quality and ensures consistent removal regardless of the color of the filters.
