Latest Patents

One of Saito's latest patents involves a light guide plate for a display panel that features arcuate grooves formed in both the incident and upper surfaces. This innovative design includes a liquid crystal display device that comprises a liquid crystal panel and an illumination device. The illumination device is equipped with a light guide plate and at least one spot light source positioned on one side surface of the light guide plate. The light guide plate is characterized by numerous upper-surface arcuate cross-sectional grooves oriented orthogonally to the side surface facing the liquid crystal panel. Additionally, it features light-incident-surface arcuate cross-sectional grooves formed in the thickness direction of the light guide plate, which face the position of the spot light source. A specific relationship is established between the contact angles of the upper-surface and light-incident-surface grooves, optimizing the light distribution in the display.

Another notable patent by Saito pertains to a liquid crystal display device that incorporates a transparent sheet adhered to a diffusion plate facing a light source, such as cold cathode fluorescent lamps. The edges of the transparent sheet and the diffusion plate are sealed using pressure-sensitive adhesive double-sided tape, ensuring that the drying conditions on both sides of the diffusing plate remain equal. This innovation significantly improves the overall performance of the liquid crystal display.
