Embodiment 1

[0031] In this embodiment, the display layer is a microlens array with a period of 0.0729 mm, arranged in a hexagonal manner, such as figure 1 shown.

[0032] The graphic of the bottom unit is "√", and the size of the subunits is 0.06mm. They are arranged in a hexagonal manner with a period of 0.0729mm. The local structure is as follows figure 2 shown.

[0033] Weak transformation of the coordinates of the display layer Coordinate weak transformation on the bottom layer Get the local part of the transformed micrographic array such as image 3 shown.

[0034] The preparation process of the dynamic display film is as follows:

[0035] Step 1. Design the required graphic array on the computer, and prepare a photolithography mask.

[0036] Step 2. Spin-coat photoresist on the glass substrate. The process is to drop glue to the center of the substrate until the area of ​​the photoresist accounts for one-fifth to one-sixth of the area of ​​the glass substrate. The photores...

Abstract

The invention discloses a dynamic display film and a preparation method thereof and relates to the technical field of naked eye visible dynamic display films. The display panel comprises a base layer,a bottom layer and a display layer, wherein the display layer is a micro lens array or a small hole array, the micro lens array or the small hole array is arranged according to a quadrilateral or hexagonal array, a period interval T of the micro lens array or the small hole array is 0.04-0.5 mm, the bottom layer is a micro pattern array layer, a plurality of subunits are arranged on the bottom layer to form a micro pattern array layer, and the sizes of the subunits are smaller than the period interval T. The display panel is advantaged in that magnification and naked eye visibility of a tinygraph can be realized, a dynamic display film can realize a display mode of translation, floating and sinking, can realize rotational symmetry of the magnified graph, can realize circular motion and radial motion along with the change of the visual angle, and the display panel has a strong dynamic effect, the dynamic display film can be applied to anti-counterfeiting and decorative materials.

Description

technical field [0001] The invention relates to the technical field of a dynamic display film visible to the naked eye, and more specifically relates to a dynamic display film and a preparation method thereof. Background technique [0002] Moiré is an interference phenomenon in which gratings with a specific period are superimposed in a certain way. Amidror and his colleagues have done a lot of research on the Moiré effect and formed a relatively mature theory. The Fourier analysis model of Moiré is the most widely used at present. Because moire pattern can be recognized by human eyes, and the purpose of hiding information can be realized through a certain design, it is applied in cryptography and anti-counterfeiting. [0003] In 2000, Desmedt combined Moiré theory with the idea of ​​visual cryptography, and proposed a specified moiré pattern construction algorithm. This method generates two basic layers according to the hidden information and image information, and the hi...
