As shown in fig. 2, which is a schematic view of a transparent imprinting adhesive layer according to an embodiment of the present invention, a micro-texture structure of the transparent imprinting adhesive layer 101 includes triangular prisms 102 having triangular cross-sections 102a, and various basic transparent shadows can be realized by adjusting shapes of the triangular cross-sections and the paths of the triangular prism arrangements. Specifically, the first cutting portions are formed by cutting a whole section of a cylinder of a part of the triangular prism with a preset length (in the arrangement direction), and the first cutting portions are arranged at intervals along the extension direction of the triangular prism. For a certain cutting region, the first cutting portions are combined to form a pattern, such as a triangular pattern shown in fig. 2, and the pattern is arranged at intervals in the arrangement direction of the triangular prisms (i.e. the interval distance may be the same or different, or the pattern is arranged in a gradient manner in the arrangement direction of the triangular prisms). The pattern is in a region with a different transparency than other regions, so that the visually transparent film can realize various different basic clear shadows. In the present embodiment, three sides (e.g., side 102a) of the triangular prism are regular quadrangle or irregular quadrangle. In one embodiment, the lengths (length L along the arrangement direction, see fig. 3) of two adjacent triangular prisms 202 of which triangular prisms are arranged on a curve (as shown in fig. 4) may be equal or different, so as to realize various different basic clear shadows.
In one embodiment, the plurality of first cutting portions are combined in a pattern for a certain cutting region, such as a stripe (square) pattern shown in fig. 4, and the intervals t1 between the patterns may be the same or different (see fig. 5), or the patterns may be arranged in a gradient/inclined to a certain direction in the arrangement direction of the triangular prisms. The transparency of the pattern in the area is different from that of other areas, so that the transparent film can realize various basic transparent light shadows in vision, and defects such as spots and the like cannot appear in vision. In the present embodiment, the triangular prisms are intermittently arranged in a curved shape in the arrangement direction, and in other embodiments, the triangular prisms are continuously arranged in a curved shape in the arrangement direction.
As a modification of the embodiment of fig. 2, as shown in example 4, a schematic view of the micro-texture structure of the transparent imprinting glue layer 301 according to an embodiment of the present application is shown, and the micro-texture structure includes: triangular prism 302, triangular prism 304, and irregular triangular prism 303, and the top of irregular triangular prism 303 has a flat portion 303a (sometimes, the flat portion has a certain arc). The triangular prisms 302, 304 and 303 are arranged according to a predetermined pattern (e.g., according to a straight line or a curved line), wherein the cross-section of each triangular prism is triangular (may be any triangular, such as an equilateral triangle, an isosceles triangle, etc.), three sides of each triangular prism are regular quadrangle or irregular quadrangle, the heights of two adjacent triangular prisms arranged on a straight line or a curved line may be equal or unequal, and an irregular triangular prism with a missing top is arranged between two adjacent triangular prisms arranged on a straight line or a curved line. The cross section of the special triangular prism can be any quadrangle, and four side surfaces of the special triangular prism are regular quadrangles or irregular quadrangles. And the parameters of the adjacent special triangular prisms are set in a variable manner. Such as: the height of the irregular triangular prism gradually decreases/gradually increases/periodically changes from one side to the other side. In the present embodiment, triangular columns 302 are arranged continuously, triangular columns 304 are arranged intermittently,

Or the cut part is the apex of the triangular prism (as shown in fig. 6), the bottom surface in fig. 6 is unchanged, and the atomization effect of different degrees can be increased on the basis of the transparent light shadow due to the fact that the height H1 (also called thickness) in the thickness direction of the irregular triangular prism with different cutting sizes is different (namely, the size of the top flat part 303a of each row of irregular triangular prisms is adjusted), so that various transitions of the light shadow from real to virtual are realized on the same optical film, and the visual effect is improved. In this embodiment, the interval t between two adjacent triangular prisms 304 may be the same or different. The height H1 of the shaped triangular prism gradually decreases/gradually increases/periodically changes from side to side in the direction I. In other embodiments, the height H1 of the shaped triangular prism varies periodically or randomly, which increases the atomization effect to different degrees based on the clear light. In the present embodiment, the irregularly shaped triangular prisms may have the same or different lengths in the direction of the straight or curved path.

In the present embodiment, the irregular rectangular pyramid 402 (see fig. 8) has: a base 4021 of a certain height H; the four sides 4022 of the base 4021 are regular quadrilateral or irregular quadrilateral; two opposite surfaces of a cone body of the special-shaped rectangular pyramid above the base are triangular 4022, and the other two opposite surfaces are trapezoidal 4023. Therefore, various different basic transparent light shadows can be realized by adjusting the shape and the arrangement path of the rectangular pyramid; the atomization effect of different degrees can be increased on the basis of the transparent light shadow by adjusting the height H and the shapes of the four side surfaces of the special-shaped rectangular pyramid base 4021, so that various transitions of the light shadow from real to virtual can be realized on the same optical film.
