Abstract
This application discloses an optical film, comprising: a polymer having a first surface and a second surface, the first surface and the second surface opposing to each other; a microlens structure being formed on the first surface, an accommodation structure being formed on the second surface, the accommodation structure accommodating a number of pattern structures imaging through the microlens structure; the microlens structure and the accommodation structure being integral; and the micro-focusing units and the pattern structures being adapted to each other, so that the optical film forms at least one image floating in the optical film when the optical film is viewed from a side of the pattern structures or a side of the micro-focusing units. A substrate layer is omitted from the optical film, hence, the optical film is reduced in thickness, and mechanical performance is not good, which makes the optical film easy to be cut in thermoprinting.
