Latest Patents
Fujikake's latest patents include an optical-diffusion film for display and a display device using the same. The first patent describes an optical-diffusion film that efficiently diffuses and emits highly directional light from a collimated backlight. This innovation prevents the straight transmission of light, ensuring that the image display light is effectively projected toward the front of the display device. The film features a columnar structure with pillar-shaped objects arranged closely in a low refractive index region, with a film thickness ranging from 60 to 700 μm and a haze value of 80% or more.
The second patent focuses on an optical-diffusion film for reflective display devices. This film efficiently diffuses external light incident from various angles, enhancing the image display quality. It is a single-layered film created by photocuring a composition that includes multiple polymerizable compounds with different refractive indices. The film thickness also ranges from 60 to 700 μm, and it maintains a haze value of 70% or more across varying incident angles during photocuring.
