For example, the thickness of the grating animation film is 100 μm-800 μm.

[0033] In one embodiment, the number of animation frames is less than or equal to 80.

The pattern layer 2 comprises a sampling diagram 21 which comprises a plurality of sampling units arranged in rows, and the sampling unit is a sampling strip 211 in the embodiment, the sampling strip 211 is arranged in one-to-one correspondence with the cylindrical lens grating 11, and the axial direction of the cylindrical lens grating 11 is arranged in parallel with the direction of the sampling strip 211. The sampling diagram 21 comprises pattern information of a plurality of animation frames 22, each animation frame 22 is divided into a plurality of illustration frames 221, and the plurality of illustration frames 221 of the plurality of animation frames 22 are arranged in sequence. Each sampling strip 211 comprises one illustration frame 221 of each animation frame 22. In the embodiment, the width of the illustration frame 221 is less than 20 μm. In this way, more illustration frames 221 can be arranged in the unit width sampling strip 211, so that the action or animation continuity is improved, the visual comfort is improved, and the user experience is improved. In other embodiments, the animation frame 22 can be arranged with unequal illustration frames 221, that is, the widths of the illustration frames 221 are inconsistent; the sampling strip 211 comprises the illustration frames 221 of part of the animation frames 22, that is, the sampling of the illustration frames 221 does not affect the display pattern effect of the animation frames 22.

[0042] In this embodiment, the grating animation film 100 further comprises an encapsulation layer 3 covering the focusing layer 1, and the difference between the refractive index of the focusing layer 1 and the refractive index of the encapsulation layer 3 is greater than or equal to 0.5. Thus, a flat surface is obtained, which not only enhances the visual effect, but also improves the durability of the product, and eliminates the defects of the existing grating animation touch sound.

[0043] In this embodiment, the width of the cylindrical lens grating 11 is less than or equal to 80 μm, and the visual effect will not be able to see the stripe of the cylindrical lens grating 11, so that the picture is more delicate. The number of animation frames 22 is preferably less than or equal to 80 frames, for example, 20, 30, 40, the continuity of the action or animation is good, and the visual effect is enhanced.

[0044] In this embodiment, the pattern layer 2 comprises a bearing layer 23 having a groove 231 and an ink 24 filled in the groove 231. The width of the groove 231 is greater than or equal to 1 μm.

At the same time, the width of the illustration frame 221 is reduced, which will be matched with the cylindrical lens grating 11 with smaller focal length. The width of the cylindrical lens grating 11 is reduced, and more illustration frames 221 can be arranged in a unit width, so that the quality of the picture is improved, and the continuity of the action or animation is increased. The thickness of the focusing layer 1 and the pattern layer 2 can also be greatly reduced, which can be 100 μm-800 μm, for example, 125 μm, 150 μm, 200 μm, 500 μm, etc. Thus, a new grating animation film 100 is obtained, which can be applied to more scenes, for example, a grating animation printed matter can be formed, and the grating animation printed matter can be applied to the cover plate of an electronic product, opening up a new application market.

[0045] Please continue to refer to Figures 1 to 5 The principle and implementation steps of the grating animation film 100 of the present application are as follows:

[0046] S11: Prepare a cylindrical lens grating master, prepare a rectangular cylindrical lens grating master with a size of 170 mm (length) x 80 mm (width). Ensure that the axis direction of the cylindrical lens grating is parallel to the long side of the master, and the cylindrical lens grating period is 80 μm.

[0047] S12: Make a sample picture master, use the "compression" principle and "isolation" principle to make a sample picture containing multiple animation frame information. The sample picture master must accurately match the prepared cylindrical lens grating master to ensure accurate alignment in the subsequent steps. In this embodiment, it is a 30-frame animation picture.

[0048] The "compression" principle refers to compressing multiple animation frames into one plane, and the "isolation" principle refers to reflecting different angles of the cylindrical lens grating to make the observer see different animation frames at different viewing angles.

[0049] S121: Obtain animation frame information, obtain a series of pictures containing animation frame information using a camera or a computer, etc. The motion of the butterfly flapping its wings is divided into 30 consecutive animation frames.

[0050] S122: Generate a sample picture, according to the "compression" principle and the "isolation" principle of the cylindrical lens grating, use computer software or printing technology to process the information of each animation frame, generate a sample picture containing all the animation frame information. This step requires high-precision image processing technology to ensure smooth transition between each animation frame. The sample strip of the sample picture is composed of the animation frames, and the size of the sample strip is adjusted according to the specific requirements and the cylindrical lens grating used. The axis direction of the cylindrical lens grating is parallel to the direction of the sample strip in the sample picture. After the cylindrical lens grating is aligned with the sample picture, the entire animation frame image can be seen through the cylindrical lens grating, that is, a complete animation frame image can be seen.

[0051] The principle is explained as follows, please refer to Figure 2 Take 3 animation frames as an example, A, B, and C are the original frame images of the animation. According to the specifications of the cylindrical lens grating used, the animation frames 22 are divided into strips, that is, the animation frames Al, A2, A3, A4…, Bl, B2, B3, B4…, C1, C2, C3, C4…, and then these animation frames are rearranged into Al, Bl, Cl, A2, B2, C2, A3, B3, C3, A4, B4, C4…, forming a sample picture 21. The finished product of the sample picture 21 is shown in Figure 3 The sample picture 21 includes multiple sample strips 211, each sample strip 211 includes 3 animation frames, that is, A1, B1, C1 form a sample strip, A2, B2, C2 form a second sample strip… The light exit principle of the cylindrical lens grating 11 is shown in Figure 4 Different animation frames can be observed through the cylindrical lens grating. According to its principle, please refer to Figure 5 The viewer's eyes are parallel to the axis of the cylindrical lens grating 11. Figure 5 In a, the animation frame A animation frames Al, A2, A3 pass through the corresponding cylindrical lens grating, and exit to the viewer's eyes (E). At this time, part of the reflected light of the other animation frame animation frames cannot exit outside the cylindrical lens grating due to the refraction of the cylindrical surface, and the light that can exit is also reflected to the eyes (E) after passing through the axis, so the eyes (E) can only see the animation frame A. Similarly, Figure 5In figure b, the eye (E) can only see animation frame B; in figure c, the eye (E) can only see animation frame C. Seeing C from A presents a continuous motion, thus making the picture move.

[0052] S13: Alignment Imprinting. After precisely aligning the above sampling master image with the cylindrical lens grating master image, imprinting is used to transfer them. UV adhesive with a refractive index of 1.91 is used in this process.

[0053] In another embodiment, please refer to Figure 6 The lenticular animation film 100 also includes a substrate layer 4, which is located between the focusing layer 1 and the pattern layer 2. Taking a PET film as an example, a PET film is prepared, UV adhesive is applied to the PET film, and the UV adhesive is imprinted and cured. After demolding, a cylindrical lens grating 11 is formed on one side of the PET film, and a carrier layer 22 with grooves 231 is formed on the other side.

[0054] S14: Print black ink onto the surface of the sampling pattern. The groove 231 is filled with black ink to form the sampling pattern 21. In other embodiments, other colors such as red, green, yellow, gray, silver, and polychrome can be printed.

[0055] S15: Encapsulation and surface treatment: A layer of UV adhesive with a refractive index of 1.41 is coated onto the surface of the focusing layer 1, and the surface structure is filled to make it smooth and flat. The refractive index difference between the encapsulation layer 3 and the focusing layer 1 is 0.5, and the encapsulation layer 3 will not affect the optical effect of the lenticular lens grating 11. This not only enhances the visual effect but also improves the durability of the product and eliminates tactile noise.

[0056] The lenticular animation film 100 of this application allows for the observation of a continuous and smooth animation effect by gently shaking the finished product, showcasing a unique visual charm. The lenticular grating consists of a series of slender lenticular lenses that refract light at specific angles, thereby displaying different animation frames. By rotating the film or shifting the viewing angle, each animation frame, composed of illustrated frames, is reflected sequentially through the lenticular grating to the viewer's eye. The frames are seen by the eye in sequence within a certain time frame, thus creating the animation effect.

[0057] Please refer to Figure 7 This application discloses another lenticular animation film 200, which includes a focusing layer 51, a pattern layer 52, an encapsulation layer 53, and a substrate layer 54. The substrate layer 54 is located between the focusing layer 51 and the pattern layer 52, and the encapsulation layer 53 is deposited on the focusing layer 51. The pattern layer 52 is a patterned coating layer, and the width of the illustration frame is greater than or equal to 3 μm. The fabrication steps of the lenticular animation film 200 are as follows:

[0058] S21: Prepare the cylindrical grating master plate, prepare a rectangular cylindrical grating master plate with a size of 170mm (length) x 80mm (width). Ensure that the axial direction of the cylindrical grating is parallel to the long side of the master plate, and the cylindrical grating period is 80μm.

[0059] S22: Make a sample picture master plate, use the "compression" principle and "isolation" principle to make a sample picture containing multiple animation frame information. The sample picture master plate must be accurately matched with the prepared cylindrical grating master plate to ensure accurate alignment in subsequent steps. In this embodiment, it is a 30-frame animation picture.

[0060] S23: Transfer the cylindrical grating master plate to a 100μm PC substrate, silver plating on the other side of the PC substrate, spin coating photoresist, and aligning and exposing on the photoetching machine. Similarly, the refractive index of the glue used in this process is 1.91.

[0061] S24: After exposure, the surface of the colored area will be covered with glue. Remove the plating color by stripping solution, and then remove the residual photoresist on the surface by degreasing process, finally get a sample picture with plating color.

[0062] S25: Packaging and surface treatment, in order to further improve the quality of the finished product, a layer of glue with a refractive index of 1.41 is coated on the surface of the cylindrical grating, and the surface structure is filled to make it smooth and flat. Not only enhances the visual effect, but also improves the durability of the product.

[0063] The grating animation film disclosed in the present application forms a pattern layer by nano-imprinting or plating, which can effectively reduce the width of the illustration frame, and the width of the illustration frame is less than 20μm, thereby reducing the width of the sample strip, so as to be suitable for the cylindrical grating with a narrower width, and further the width of the cylindrical light grating is less than 150μm or even less than 80μm, which is invisible to the naked eye, so as to improve the pattern effect and increase the visual effect. At the same time, more illustration frames can be set in the width of the unit sample strip, which increases the number of animation frames, so as to make the action more coherent and the visual effect more outstanding. The packaging layer is covered on the cylindrical light grating, the optical effect of the cylindrical light grating is ensured by the difference in refractive index, and the surface is smooth, which eliminates the abnormal sound and improves the durability.

[0064] The above embodiments only express several embodiments of the present application, and the description is more specific and detailed, but it cannot be understood as limiting the scope of the patent of the present application. It should be noted that for ordinary skilled persons in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which are within the scope of protection of the present application. Therefore, the protection scope of the patent of the present application should be subject to the appended claims.
