Title:
OPTICAL IMAGING FILM
Document Type and Number:
WIPO Patent Application WO/2021/036427
Kind Code:
A1
Abstract:
An optical imaging film comprises: a focusing layer (2) having two or more focusing structures (21); and an image layer (1) having two or more sub-images (111a), wherein at least part of the sub-images (111a) are configured as part of a pattern of a preset image (111). The focusing layer (2) matches the image layer (1), and the focusing structures (21) correspond to the sub-images (111a), such that the optical imaging film presents a magnified image of the preset image (111). The image layer (1) of the optical imaging film comprises multiple sub-images (111a), and each of the sub-images (111a) and a corresponding focusing structure (21) are matched together to form a magnified image. Compared with the prior art, the sub-image (111a) is larger, thus increasing the size of the image, and enabling the optical imaging film to increase the magnification of the preset image (111).
