摘要： An optical imaging film includes: a focusing layer, having two or more focusing structures; and a graphic layer, having two or more sub-graphics, and at least part of the sub-graphics are configured as a partial pattern of a preset graphic. The focusing layer is adapted to the graphic layer, and the focusing structures are provided corresponding to the sub-graphics, such that the optical imaging film presents an image of the preset graphic with a magnifying effect. The graphic layer of the optical imaging film includes a plurality of sub-graphics, and each of the plurality of the sub-graphics interacts with the corresponding focusing structure to form an image with a magnifying effect. Therefore, the sub-graphic is relatively large, thereby increasing the size of the images. That is, the optical imaging film can increase the magnification of the preset graphic.

摘要： A stereo imaging film includes: a focusing layer including at least one focusing unit, the at least one focusing unit each includes a plurality of micro-nano structures; and a graphic layer including at least two graphic units in a same layer, the at least two graphic units each include a plurality of micrographics, the plurality of micrographics of the at least two graphic units have different arrangements. One of the at least one focusing unit is corresponding to the at least two graphic units, and the at least two graphic units form graphic images with different image heights through the focusing unit. Each focusing unit forms graphic images through the focusing units, and thus the technical problem of poor stereo sensation of the suspended image is solved.
