Referring to fig. 1, a decoration film 10 according to an embodiment of the present invention includes a substrate 11, an adhesion layer 12 and a first color layer 13 are disposed on one side of the substrate 11, a groove structure 122 is formed on a surface of the adhesion layer 12 away from the substrate 11, the groove structure 122 is provided with a groove 1222, the first color layer 13 is at least partially located in the groove 122, and a second color layer 14 is disposed on the other side of the substrate 11.
In the above-mentioned decorating film 10, the first color layer 13 and the second color layer 14 are respectively located on both sides of the substrate 11, which is beneficial to manufacturing the decorating film 10, the first color layer 13 is located in the groove structure 122, the gradual change effect of the first color layer 13 can be realized by controlling the size and the interval change of the groove structure 122, and the gradual change effect between two colors with larger color difference can be further realized by the cooperation of the second color layer 14 and the first color layer 13.
In the existing coating process, the effect of realizing color gradient through the coating layer is usually the gradient between adjacent colors, for example, the gradient between blue and green and the gradient between yellow and green, and the color crossing of two colors with larger color difference is difficult to realize. The decoration film 10 of the embodiment of the invention realizes the gradual change of the first color layer 13 through the groove structure 122, and the first color layer 13 and the second color layer 14 are positioned at two sides of the substrate 11, so that the influence between the first color layer 13 and the second color layer 14 is small, therefore, the first color layer 13 and the second color layer 14 are matched to realize the gradual change effect between two colors with larger chromatic aberration by adjusting the colors of the first color layer 13 and the second color layer 14, and more individual requirements of the decoration film 10 are met. For example, the first color layer 13 may be red, the second color layer 14 may be blue or green, and the like, so as to realize a gradual change effect between two colors with a large color difference.
In some embodiments, the substrate 11 includes polyethylene terephthalate (PET), polymethyl methacrylate (PMMA), or an explosion-proof film, etc.
Referring to fig. 2 to 4, in some embodiments, the groove structure 122 defines a plurality of grooves 1222, the size of the grooves 1222 is gradually increased or decreased in a predetermined region of the adhesion layer 12 along a direction parallel to the substrate 11, and a distance d between the grooves 1222 is gradually decreased or increased in the predetermined region of the adhesion layer 12 along the direction parallel to the substrate 11.
Thus, when the sizes of the plurality of grooves 1222 are gradually increased or decreased along the direction parallel to the substrate 11, the area covered by the first color layer 13 in each groove 1222 is also changed along with the size of the groove 1222, the distance d between the plurality of grooves 1222 is gradually decreased or increased along the direction parallel to the substrate 11, that is, the area not covered by the first color layer 13 is changed along with the distance d between the plurality of grooves 1222, and the second color layer 14 can achieve a gradual effect between two different colors through the distance between the plurality of grooves 1222 and the first color layer 13.
In some embodiments, the contour of the plurality of grooves 1222 on the surface of the attachment layer 12 includes one or more of a circle, an ellipse, a triangle, and a quadrilateral. In the illustrated embodiment, the contour of the plurality of grooves 1222 on the surface of the attachment layer 12 is square, and in other embodiments, the contour of the grooves 1222 on the surface of the attachment layer 12 may be other polygons, which is not specifically limited herein.
In some embodiments, the grooves 1222 are in a continuous grid, that is, the grooves 1222 are formed by staggered continuous channels, and the channel width of the grooves 1222 gradually increases or decreases in a direction parallel to the substrate 11 at a predetermined region of the adhesion layer 12.
Thus, when the first color layer 13 is located in the groove structure 122, the first color layer 13 is filled in the grid-shaped channel, the coverage area of the first color layer 13 is controlled by designing the width of the channel, the size and the distance of the corresponding channel spacing portion are changed accordingly, and the second color layer 14 can realize the gradual change effect between two colors with larger chromatic aberration through the channel spacing portion and the first color layer 13.
The groove structure 122 forms a recess at the groove 1222 and a protrusion outside the groove 1222, and the groove structure 122 includes a plurality of grooves 1222 communicating with the groove 1222 in a grid-like pattern, which may be two complementary surface structures. Specifically, when the groove structure 122 includes a plurality of grooves 1222, the positions of the grooves 1222 may correspond to the positions of the protrusions when the grooves 1222 are in a connected grid pattern, and when the groove structure 122 includes a plurality of grooves 1222, the areas outside the grooves 1222 may correspond to the positions of the channels when the grooves 1222 are in a connected grid pattern. In one example, the spacing d between the plurality of recesses 1222 when the recess structure 122 includes the plurality of recesses 1222 may correspond to the width of the channel when the recesses 1222 are in a grid. In the illustrated embodiment, the recess structure 122 includes a plurality of recesses 1222.
It should be noted that, as shown in fig. 2, the predetermined area of the attachment layer 12 may be an area of the entire attachment layer 12, and the entire attachment layer 12 may be attached with the first color layer 13, that is, all areas of the decoration film 10 may form a gradual change effect; as shown in fig. 3 and 4, the predetermined area of the adhesive layer 12 may also be an area of the middle portion or an area of the peripheral portion of the adhesive layer 12, and accordingly, the decoration film 10 may form a gradual change effect in the area corresponding to the predetermined area, and the decoration film 10 may have a uniform filling color outside the predetermined area.
The direction parallel to the substrate 11 may be one direction or a plurality of directions, and as shown in fig. 2, the size of the groove 1222 is gradually reduced in a direction from one side of the substrate 11 to the other side; as shown in fig. 3 and 4, the size of the groove 1222 is gradually reduced from the middle in the direction of the four sides of the substrate 11. In some embodiments, the size of the plurality of grooves 1222, the increasing or decreasing range of the spacing d between the plurality of grooves 1222 or the channel width along the direction parallel to the substrate 11 may be flexibly configured according to actual needs, and are not particularly limited herein.
In some embodiments, the adhesive layer 12 comprises a uv curable glue, and the groove structures 122 are formed in the adhesive layer 12 by an embossing technique.
Specifically, the imprinting technique may imprint the adhesive layer 12 in a gel-like state using a mold (not shown) having a protrusion structure (not shown) complementary to the groove structure 122 such that the groove 1222 is formed on the surface of the adhesive layer 12 after imprinting, and then curing the adhesive layer 12 to form the stable groove structure 122. The ultraviolet curing glue is used as the adhesion layer 12, the curing mode is simple, a transparent film layer can be formed after curing to ensure that light of the second color layer 14 can penetrate through, the adhesion capability is strong, and the adhesion of the first color layer 13 in the groove structure 122 is facilitated. The side of the adhesive layer 12 having the groove structure 122 can be filled with the liquid first color layer 13 by a doctor blade method into the groove structure 122, and then the first color layer 13 is cured and adhered into the groove 1222.
In one example, the bump structure includes a plurality of bumps (not shown) spaced apart, and when the mold is pressed on the adhesive layer 12 in a gel-like manner, the adhesive layer 12 fills the spaces between the bumps, so that the adhesive layer 12 is cured to form a plurality of spaced apart recesses 1222 at the plurality of bumps. The sizes of the plurality of protrusions are gradually increased or decreased along the direction parallel to the substrate 11, the intervals among the plurality of protrusions are gradually increased or decreased along the direction parallel to the substrate 11, and the shape of the plurality of protrusions can be one or more of a circle, an ellipse, a triangle and a quadrangle.
In another example, the raised structure is in the form of a grid, and when the mold is pressed on the adhesive layer 12 in the form of a gel, the adhesive layer 12 fills the mesh portions of the grid, so that the adhesive layer 12 forms interconnected channels at the raised structure after curing. The mesh width of the grid-like projection structure gradually increases or decreases in a direction parallel to the substrate 11.
In one embodiment, the first color layer 13 is located in the groove 1222, i.e. the thickness of the first color layer 13 is less than or equal to the depth of the groove 1222, and the first color layer 13 is completely filled in the groove 1222. In another example, the first color layer 13 is partially disposed in the groove 1222, i.e. the thickness of the first color layer 13 can be slightly larger than the depth of the groove 1222, for example, when the liquid first color layer 13 is drawn down, the thickness of the first color layer 13 outside the groove 1222 is much smaller than the depth of the groove 1222, the decoration film 12 can still achieve the opaque property of the first color layer 13 at the groove 1222, and has a certain transparency outside the groove 1222 to make the color of the second color layer 14 transparent, which is beneficial for the processing of the first color layer 13.
The embossing technology is simple in process, in the groove structure 122 formed by the embossing technology, the dimension of the size or the channel width of the groove 1222 can be more precisely controlled by the mold, the stability of the molding of the groove structure 122 is ensured, and the dimension control of the size or the channel width of the groove 1222 can reach the micrometer level, so that the gradual change effect of the decoration film 10 is finer.
In some embodiments, the second color layer 14 is a plated layer formed on the substrate 11 by a non-conductive plating technique.
It is understood that the first color layer 13 can achieve a gradual change effect, and the second color layer 14 is located on a different side of the substrate 11 from the first color layer 13, in this case, the second color layer 14 can be a uniform film layer. Therefore, the non-conductive electroplating technology can form a plating layer with good uniformity and high compactness, and can realize the metal appearance effect of different colors, so that the second color layer 14 and the first color layer 13 form a richer gradual change effect.
In some embodiments, the second color layer 14 may be a uniform color layer, or the second color layer 14 may be a non-uniform color layer.
Specifically, in some embodiments, the second color layer 14 is a uniform color layer, that is, the second color layer 14 presents a single color effect, and the first color layer 13 and the second color layer 14 cooperate to achieve a gradual change effect between two uniform colors. Wherein, the uniform color layer can be a uniform coating layer or a uniform printing ink layer, etc.
In other embodiments, the second color layer 14 is a non-uniform color layer, wherein the non-uniform color layer can be a non-uniform distribution of a single color or a combination of colors. As shown in fig. 5, the second color layer 14 is divided into a plurality of regions, each region forming a different color effect to realize a non-uniform color layer having a plurality of colors, so that the second color layer 14 and the first color layer 13 cooperate to allow the decoration film to form a gradation effect between two different colors in different regions.
In particular, referring to fig. 6 and 7, in one example, the non-uniform color layer may be a gradient color layer, and the gradient color layer may be a gradient effect in a single color or a gradient effect between different colors. In this way, the gradual overlapping of the first color layer 13 and the second color layer 14 can achieve a richer gradual effect. Further, as shown in fig. 7, the second color layer 14 is divided into a plurality of regions, each region forms a gradient effect with different colors and/or different gradient trends, so that the decoration film 10 can realize different gradient superposition in different regions, and the gradient effect of the decoration film 10 is further enriched.
The second color layer 14 shown in fig. 6 shows a single-color gradient effect, and the second color layer 14 shown in fig. 7 shows multiple gradient effects, specifically, multiple gradient effects of one color or multiple colors respectively forming multiple different gradient effects.
It should be noted that, when the second color layer 14 has a single-color gradient effect, the gradient effect of the second color layer 14 may be different from the gradient effect of the first color layer 13. The first color layer 13 is prevented from blocking the second color layer 14, so that the decoration film 10 cannot realize gradual change superposition of the first color layer 13 and the second color layer 14.
Accordingly, the non-uniform color layer may be a non-uniform coating layer and/or a non-uniform ink layer, etc.
In the embodiments shown in fig. 5 and fig. 7, the area division of the second color layer 14 is only used as an example, and in other embodiments, the second color layer 14 may also perform area division according to actual needs.
Referring to fig. 8, in some embodiments, the decoration film 10 includes a uv-curable adhesive layer 15, and the uv-curable adhesive layer 15 is located between the substrate 11 and the coating layer.
It can be understood that the decoration film 10 can better adhere to the substrate 11 and the coating layer through the uv-curing glue layer 15, and ensure the stability of the second color layer 14. For example, when the substrate 11 is PET, the substrate has high chemical stability and low surface tension, and is not easy to be directly coated on the surface of the substrate 11, the uv-curable adhesive can be well bonded with various plastics and metals, and the coating on the uv-curable adhesive layer 15 can make the coating layer better adhere to the decorative film 10, so as to ensure the reliability of the second color layer 14.
In certain embodiments, the substrate 11 comprises a transparent substrate or a colored substrate.
In one example, the substrate 11 is a transparent substrate, which is beneficial to light transmission, and the second color layer 14 can be transmitted through the substrate 11 and the adhesion layer 12 to achieve the corresponding effect with the first color layer 13.
In another example, the substrate 11 is a colored substrate. The colored substrate may have a certain transparency, and at this time, the second color layer 14 may be a coating layer with a high brightness color, for example, a coating layer with a silver color, so that the second color layer 14 may reflect high brightness light to make the color of the substrate 11 more transparent, so that the gradient effect of the decoration film 10 is better.
Referring to fig. 9, in some embodiments, an ink layer 16 is disposed on a side of the second color layer 14 away from the substrate 11.
Specifically, the ink layer 16 may be a capping ink layer. Therefore, the bottom-covering ink layer can shield light to cover the internal elements of the electronic device 100, so that the light at the back of the decorative film 10 is prevented from penetrating through the decorative film 10 to influence the gradual change effect of the decorative film 10, and meanwhile, the bottom-covering ink layer can also protect the second color layer 14 and reduce the damage of the second color layer 14.
Wherein, the side of the decoration film 10 provided with the first color layer 13 is the front side of the decoration film 10, and the side provided with the second color layer 14 is the back side of the decoration film 10, and the gradual change effect of the decoration film 10 can be observed from the front side of the decoration film 10.
In one example, when the second color layer 14 is a coating layer, the ink layer 16 needs to be printed on one side of the coating layer under the influence of the coating thickness, so that the ink layer 16 and the second color layer 14 cooperate to achieve a corresponding color effect, thereby ensuring the appearance effect of the decoration film 10.
In some embodiments, the first color layer 13 and/or the second color layer 14 are inks.
Therefore, the ink can be configured with various color effects with different hues, lightness and unsaturation degrees according to the needs of users, so that the color selection of the first color layer 13 and/or the second color layer 14 is enriched, and the requirement of the gradient color of the decorative film 10 is met. Wherein, in order to increase the adhesion effect of the ink, the ink can be printed on the ultraviolet curing glue.
Referring to fig. 10, in some embodiments, a bonding adhesive layer 17 is disposed on a side of the first color layer 13 away from the substrate 11, and the bonding adhesive layer 17 covers the first color layer 13.
Therefore, the adhesive layer 17 can protect the first color layer 13, reduce the damage of the first color layer 13, and increase the reliability of the decoration film 10. In some embodiments, the decoration film 10 may be further attached to the housing 20 of the electronic device 100 by an adhesive layer 17.
Specifically, the adhesive layer 17 may be an optical adhesive layer. The optical cement has a good laminating effect, a transparent optical cement layer can be formed after curing, and the appearance effect of the decorative film 10 can be ensured by light penetrating through the optical cement layer.
The decoration film 10 of the embodiment of the invention may be formed by stamping the adhesion layer 12 with the groove structure 122 on one side of the substrate 11, filling the first color layer 13 into the groove 1222 through a doctor blade method, then forming the ultraviolet optical glue layer 15 on the other side of the substrate 11, plating or printing ink on the side of the ultraviolet optical glue layer 15 away from the substrate 11 to form the second color layer 14, printing the ink layer 16 on the side of the second color layer 14 away from the substrate 11 to form protection, coating the adhesive layer on the side of the adhesion layer 12 away from the substrate 11 to cover the first color layer 12, and finally cutting to form the decoration film 10 with a predetermined shape.
Referring to fig. 11 to 13, in the decoration film 10 according to the embodiment of the present invention, the size and the distance of the groove structure 12 can be controlled to realize the gradual change effect of the first color layer 13, and the second color layer 14 and the first color layer 13 cooperate to further realize the gradual change effect between two colors with a large color difference, so that the appearance of the decoration film 10 is enriched, and the personalized requirements of the decoration film 10 are met.
Referring to fig. 14, an electronic device 100 according to an embodiment of the present invention includes a housing 20 and the decoration film 10 according to any one of the above embodiments, wherein the decoration film 10 is disposed on a surface of the housing 20.
In the electronic device 100, the first color layer 13 and the second color layer 14 of the decoration film 10 are respectively located on two sides of the substrate 11, which is beneficial to manufacturing the decoration film 10, the first color layer 13 is located in the groove structure 122, and the gradual change effect of the first color layer 13 can be realized by controlling the size and the distance change of the groove structure 122, and the gradual change effect between two colors with larger color difference can be further realized by matching the second color layer 14 and the first color layer 13. The electronic device 100 can meet the personalized requirements through the decoration film 10, in one example, the decoration film 10 with different gradual effects can be formed by designing different groove structures 122 and colors, and then applied to electronic devices 100 of different types or models, and a user can identify the type and model of the electronic device 100 through the appearance effect of the decoration film 10.
Specifically, in some embodiments, the surface of the housing 20 may be a surface inside the electronic device 100 or a surface outside the electronic device 100. In one example, the housing 20 is made of a transparent material, such as glass or ceramic, and the decoration film 10 may be disposed on the surface of the inner side of the electronic device 100, so as to achieve the personalized requirements of the appearance of the electronic device 100.
