Document Type and Number:
WIPO Patent Application WO/2022/119281
Kind Code:
A1
Abstract:
The present invention relates to an optical film for controlling an optical path. The technical subject matter is an optical film comprising: a base film; an optical path control pattern part, which is formed on the base film and has a first refractive index; a light absorption pattern part, which is formed on the base film and has a second refractive index that is relatively smaller than the first refractive index. Therefore, provided is the optical film for accurately and highly efficiently supplying light (information light), in which information about an object is reflected, to a light receiving unit by forming, on the base film, the pattern parts having different refractive indices.
