Regarding the pattern layer 22, the pattern layer 22 is directly formed on the light emitting surface of the light guiding layer 21 by spray painting, hand painting or transfer printing; or the pattern layer 22 is a transparent plate with a pattern, the transparent plate is attached to the light emitting surface of the light guiding layer 21, and a planar pattern is directly formed on the transparent plate by spray painting, hand painting or transfer printing, or a pattern with an intaglio or relief pattern is formed on the transparent plate, which is not limited in the utility model. Furthermore, the pattern layer 22 may be disposed on the front or back of the light guiding layer 21, so as to display more patterns, which is not limited in the present utility model.

In the absence of bright light, the concealing layer 23 serves to conceal the pattern layer 22. Alternatively, the concealing layer 23 may be formed on the pattern layer 22 by spray painting, hand painting, spray painting, transfer printing, electroplating, or post-coating firing, or the concealing layer 23 may be a light-transmitting but opaque sheet or paper, which is not limited thereto by the present utility model. It should be appreciated that the thickness of the pattern layer 22 is typically less than 200 microns to facilitate the definition of the pattern when illuminated by the built-in light source.

For example, if each pattern is divided into 96 pattern bars, 288 pattern bars are added up to the pattern layer 22. Correspondingly, the light guiding layer 21 includes 288 light guiding strips 211, the 288 light guiding strips 211 are divided into 96 light guiding strip groups 201, 3 light guiding strips 211 (marked as a, b and c) are arranged in each light guiding strip group 201, and the light emitting surfaces of the 3 light guiding strips 211a, 211b and 211c are respectively provided with pattern strips of three patterns A, B, C.

the light emitting unit includes: a plurality of light-emitting strips arranged in parallel, each of the light-emitting strips being capable of emitting light for illuminating the pattern layer; dividing the plurality of light emitting strips into a plurality of light emitting strip groups, each light emitting strip group comprising: at least two adjacent parallel arranged luminous strips, wherein the two adjacent luminous strips are arranged at intervals so as to avoid mutual interference of light rays between the two luminous strips;

at least two patterns are arranged in the pattern layer, each pattern is divided into a plurality of pattern strips according to the number of luminous strip groups in the luminous unit, and the pattern strips can be spliced to form the corresponding pattern; different light-emitting strips in each light-emitting strip group respectively correspond to different patterns in the pattern layer;

wherein one luminous strip in each luminous strip group correspondingly illuminates one pattern strip of one pattern; in the working process, if one pattern in the pattern layer needs to be illuminated, all the luminous strips corresponding to the pattern in the luminous unit are illuminated.

7. The multi-pattern light transmissive display structure of claim 6, wherein: the luminous strip is LED lamp area, the luminous unit still includes: the base plate is used for attaching a plurality of LED lamp strips, the base plate is provided with a plurality of mounting grooves which are distributed in parallel, and each mounting groove is used for mounting one LED lamp strip;

a light-separating wall is formed between two adjacent mounting grooves and used for separating the light of two adjacent LED light bands;

the luminous strips corresponding to one pattern in the pattern layer are arranged at intervals, and luminous strips corresponding to other patterns are arranged between two adjacent luminous strips corresponding to the same pattern.

8. The multi-pattern light transmissive display structure of claim 6, wherein: the pattern layer is a light-transmitting plate provided with patterns, the light-transmitting plate is attached to the light-emitting surface of the light-emitting unit, and a plane pattern is directly formed on the light-transmitting plate through spray painting, hand painting or transfer printing, or a pattern with an intaglio modeling or relief modeling is formed on the light-transmitting plate.

9. The multi-pattern light transmissive display structure according to any one of claims 1-8, wherein: a concealing layer is sequentially arranged on the pattern layer, and the concealing layer is attached to the outer side of the pattern layer;

the pattern layer and the concealing layer have light transmittance;

illuminating the pattern layer when the light emitting unit emits light, and making the pattern of the pattern layer visible through the concealing layer; when the light emitting unit does not emit light, the concealing layer conceals the pattern layer so that the pattern is not visible.

10. The multi-pattern light transmissive display structure of claim 9, wherein: the hidden layer is also provided with a decorative layer, the decorative layer is attached to the outer side of the hidden layer, and the hidden layer can be seen through the decorative layer;

the decorative layer is a decorative pattern formed on the outer surface of the hidden layer through spray painting, hand painting or transfer printing; or the decorative layer is formed by spraying, painting or coating transparent resin on the hidden layer and then curing;

when the light emitting unit emits light, the pattern layer is illuminated, and the pattern of the pattern layer is displayed on the outermost decorative layer through the concealing layer; when the light emitting unit does not emit light, the concealing layer conceals the pattern layer so that the pattern is invisible, and the decorative layer is presented.
