AI Technical Summary
Technical Problem
Optical films used in high-definition image displays suffer from glare and decreased visibility due to light refraction and pixel enlargement caused by uneven surfaces, compromising display performance.
Method used
An optical film with a surface uneven shape having a core load length ratio Mr1 of 20% or less, adjusted to minimize glare and pixel interference, utilizing a phase separation method to form a sea-island structure with controlled roughness and haze levels, ensuring good anti-glare properties and reduced glare.
Benefits of technology
The optical film effectively scatters external light, prevents glare, and maintains image clarity by minimizing pixel magnification, thus enhancing display visibility and performance.
