2) Glue is smeared on the side wall of the light guide film 2, and then the blocking area 3 is adhered to the light guide film 2, so that the connection between the light guide film 2 and the blocking area 3 is completed;
glue is smeared on the side wall, far away from the light guide film 2, of the blocking area 3, then the light guide film 2 and the blocking area 3 are bonded on the substrate 1 together, and at the moment, the position, without the blocking area 3, of the light guide film 2 is bonded with the substrate 1, so that the substrate 1, the blocking area 3 and the light guide film 2 are mounted.
3) Glue is smeared on the side wall of the light guide film 2, and then the blocking area 3 is adhered to the light guide film 2, so that the connection between the light guide film 2 and the blocking area 3 is completed;
since glue is applied to the light guide film 2 at the position where the blocking area 3 is not formed, the side of the light guide film 2 to which the blocking area 3 is bonded to the substrate 1, and the substrate 1, the blocking area 3, and the light guide film 2 are mounted.
The implementation principle of the light guide structure capable of controlling the light emitting position in the embodiment of the application is as follows: when installing interval light-emitting structure, link together base plate 1, separation region 3 and light guide film 2, then open the light source and shine towards inside base plate 1, carry out total reflection after the light of light source gets into inside base plate 1, light follows light guide film 2 and jets out in the reflection process, and light makes light bright and dark dislocation through the position of separation region 3 to make the pattern diversified, avoided cutting light guide film 2, make whole work progress simpler and more convenient.
Example 2
The difference from embodiment 1 is that the connection relationship among the substrate 1, the light guiding film 2 and the blocking region 3 is: the substrate 1 and the light guiding film 2 are adhered to each other at a position where the blocking area 3 is not formed, and the substrate 1 and the blocking area 3 are adhered to each other, but a gap exists between the blocking area 3 and the light guiding film 2 and an air layer is formed, and in this embodiment, the blocking area 3 is made of a transparent material or a non-transparent material.
When light is irradiated on the substrate 1, the light can be injected into the light guide film 2 along the position where the blocking area 3 is not present, and finally emitted along the light guide film 2, so that the pattern can be displayed. The light can be further blocked by arranging an air layer between the blocking area 3 and the light guide film 2, so that the blocking effect of the light is improved.
Example 3

When light is irradiated on the substrate 1, the light can be injected into the light guide film 2 along the position where the blocking area 3 is not present, and finally emitted along the light guide film 2, so that the pattern can be displayed. The light can be further blocked by arranging an air layer between the blocking area 3 and the light guide film 2, so that the blocking effect of the light is improved.
Example 4
The difference from example 1 is that the barrier region 3 is printed, and when the barrier region 3 is printed, a layer of colored ink is printed on the substrate 1 by a printer (the printer is the prior art), thereby forming the barrier region 3. The printing step may be repeated after the ink on the substrate 1 has been dried, so that the thickness of the ink is different at different locations on the substrate 1. Because the thickness of printing ink is different, so can separate the light when light is projected to thicker printing ink department, can weaken the light when printing ink is projected to thinner printing ink department to can make the pattern light and shade that projects fall, demonstrate diversified effect.
The printing ink can be printed by adopting the inks with different colors, and when the light irradiates on the inks with different colors, the substrate 1 can project different colors, so that the colors of the patterns displayed on the substrate 1 are more diversified.
The mode that utilizes the printer to print has avoided manual fretwork pattern, can accelerate work efficiency and improve fineness, can guarantee the picture effect simultaneously.
Example 5
Referring to fig. 3, the difference from embodiment 1 is that a plurality of light guide posts 21 on the surface of the light guide film 2 are eliminated, a plurality of hollow ultrastructures 22 are provided inside the light guide film 2, and the plurality of ultrastructures 22 are equally spaced along the same straight line. Gaps exist between two adjacent ultrastructures 22, and the ultrastructures 22 are arranged on the inner side of the light guide film 2, so that the substrate 1, the blocking area 3 and the light guide film 2 are tightly attached.
When light is incident along the substrate 1, the light can be reflected to the inside of the light guiding film 2 along the position without the blocking area 3, and is emitted out of the light guiding film 2 along the gap between two adjacent ultrastructures 22, thereby realizing the effect of displaying patterns.
The above embodiments are not intended to limit the scope of the present application, so: all equivalent changes in structure, shape and principle of the application should be covered in the scope of protection of the application.
