Latest Patents
One of Katayose's latest inventions is a scanning exposure device. This device includes a stage that supports a substrate, with a space provided between the stage surface and the substrate. It features a light source unit that radiates light to a light irradiation area extending in one direction above the substrate. The scanning device moves one or both of the stage and the light source unit relatively in a scanning direction that intersects the one direction. Additionally, the scanning device includes an acceleration zone that transitions from a standstill position to where the substrate enters the light irradiation area. The stage is equipped with a light shielding member that covers the space between the stage surface and the substrate at the end part of the stage.
Another significant patent involves a color filter substrate manufacturing method. This method prevents color mixing between adjacent pixels while using an inkjet method, reducing flicker in displays such as televisions. The process includes a first inkjet step that applies inks simultaneously to at least two regions separated by a grid-shaped partition, followed by a second inkjet step that applies ink to regions not covered in the first step. This innovative approach ensures that inks are applied strategically to avoid interference between adjacent pixels.
