Although it can be laminated in various directions, such as being stacked in the left and right directions, it is shown as being stacked in the vertical direction for convenience of description.

The 3D sheet part 110 includes a convex lens part 112 having a convex lens 113 having a predetermined pattern structure on its front surface, and a lower portion of the convex lens part 112 and corresponding to a focal length of the convex lens 113.

The convex lens unit 112 is made of a transparent synthetic resin, the convex lens 113 is made in a hemispherical shape, and can be arranged in a variety of ways, such as can be arranged longitudinally, horizontally or radially. As an example, the pattern type of the convex lens 113 is 90 degrees, and the inclination of the convex lens 113 is 45 degrees, as shown in FIG. 3. As shown in FIG. 4, a pattern in which the crossing angle of the imaginary line passing through the center of the convex lens 113 is set to 60 degrees and the inclination of the convex lens 113 is arranged to be 60 degrees is preferable.

The live-printing unit 116 is formed by offset printing on the upper surface of the transparent unit 114. The live-action printing unit 116 is represented by a picture of the subject, a picture of a product, various patterns, and the like.

In addition, the three-dimensional printed portion 118 is formed on the lower surface of the transparent portion 114, and is mainly used for three-dimensional expression or a special effect or the like of the continuous pattern of the upper and lower sides. That is, the live-printing unit 116 is located at the nonfocal distance of the convex lens 113, and the three-dimensional printing unit 118 is located at the focal length of the convex lens 113. Accordingly, the three-dimensional printing unit 118 and the live-printing unit 116 may simultaneously give a sense of depth, surface, and protrusion. At this time, the three-dimensional printing unit 118 is printed in the primary color 4 degrees (C, M, Y, K) process or spot color, it is produced by the image separation operation of computer graphics. The image separation operation is performed by simultaneously executing the left and right lenticular image segmentation and the upper and lower lenticular image segmentation at the same time to obtain an output. In other words, the separated images taking into account the parallax of the left and right eyes are arranged in both up and down directions.

As such, the convex lens unit 112, the actual printing unit 116, the transparent unit 114, and the three-dimensional printing unit 118 constituting the 3D sheet unit 110 are thermally bonded by laminating or adhered to each other by an adhesive. .

The antistatic film 155 may prevent the live action display unit 150 and the transparency control unit 160 made of a transparent image film from sticking to each other.

In the present embodiment, the transparency control unit 160 is a double polymer dispersed liquid crystal panel. Each transparent conductive film is formed on a pair of substrates, and when there is no polymer voltage between the substrates, the liquid crystal molecules become irregular directions, and at different interfaces with different refractive indices. When scattering occurs, the opaque state is maintained. When voltage is applied, the direction of the liquid crystal is aligned, and the refractive indices of both coincide to maintain the transparent state. That is, in the polymer dispersed liquid crystal layer, when there is no voltage, the liquid crystal molecules become an irregular direction and scatter at the interface having different refractive indices with the medium to maintain an opaque state, and when the voltage is applied, the direction of the liquid crystal becomes uneven. The refractive indices coincide to maintain the transparent state. Accordingly, since the live display 150 is provided at the upper part and the 3D sheet part 110 is provided at the lower part of the transparency controller 160, the 2D image and the 3D image are switched according to the transparency or opacity of the transparency controller 160.
