Problems solved by technology

[0004] However, due to factors such as the size of the ink particles themselves, the resolution of the pattern formed on the surface of the 3C product shell by silk screen printing, watermarking, heat transfer printing, pad printing and IMD is relatively low.

Embodiment 1

[0071] This embodiment provides a shell with a pattern. In this embodiment, the first surface of the first layer is the exterior surface of the shell. Combine below Figure 2a to Figure 2c Be explained.

[0072] Such as Figure 2a As shown, the housing 10 provided in this embodiment includes a first layer 11 and a second layer 12 stacked together. The first layer 11 has a first surface 111 and a second surface 112 opposed to each other, and the second surface 112 is in a preset area (such as Figure 2a (Shown by the curved area in) to form a three-dimensional pattern 112a. The different thicknesses at each point of the three-dimensional pattern 112a (that is, the distance from each point to the first surface 111) correspond to the different colors of each position in the image forming the shell pattern. Step value; the second layer 12 has a third surface 123 facing the first layer 11 and a fourth surface 124 away from the first layer 11, and in the above preset area, the shape of...

Embodiment 2

[0082] This embodiment provides a shell with a pattern. In this embodiment, the fourth surface of the second layer is the exterior surface of the shell. Combine below Figure 3a with Figure 3b Be explained.

[0083] For example, such as Figure 3a As shown, in the case where the fourth surface 124 of the second layer 12 is the appearance surface of the housing 10, the gradation value of each position in the image used to form the housing pattern is actually displayed on the third surface 123 in the three-dimensional pattern. 112a is represented by the thickness at each point in the preset area. Therefore, for example, the third surface 123 may be in direct contact with the second surface 112 to better match the shape of the third surface 123 with the three-dimensional pattern 112a. In the figure, the second surface has a concave pattern as an example for description, but this embodiment is not limited to this. For example, the second surface may also have a convex pattern.

Embodiment 3

[0089] This embodiment provides a method for manufacturing a housing with a pattern, the housing including a first layer and a second layer that are stacked. Such as Figure 4 As shown, the method includes steps S1 to S6, which will be described in detail below.

[0090] Step S1: Convert an image (for example, a color photo) used to form a shell pattern into a color scale diagram. For example, the gradation map may be a grayscale image.

[0091] Step S2: Convert the chromaticity diagram obtained in step S1 into a three-dimensional image.

[0092] For example, in this step S2, the position in the three-dimensional image corresponds to the position in the color scale diagram, and the depth value of the position in the three-dimensional image corresponds to the color scale value of the position in the color scale diagram. The following uses a 256-level grayscale image as an example to illustrate the correspondence between the depth value of a position in the three-dimensional image an...

Abstract

Provided are a shell with patterns, a manufacturing method and device of the shell with the patterns, and a pattern forming method. The manufacturing method comprises the steps of forming a first layer, specifically, the first layer is provided with a first surface and a second surface, the first surface and the second surface are opposite, and the three-dimension patterns are formed in the preset area of the second surface; and forming a second layer, specifically, the second layer is provided with a third surface facing the first layer and a fourth surface away from the first layer, and in the preset area, the shape of the third surface is matched with the shape of the second surface. According to the manufacturing method, the different thicknesses of points of the three-dimension patterns correspond to the different color step values of positions in images forming the patterns, or, the different thicknesses of the points in the preset area of the third surface correspond to the different color step values of positions in images forming the patterns. The manufacturing method can increase the resolution ratio of the patterns on the surface of the shell.

Description

Technical field [0001] At least one embodiment of the present invention relates to a housing with a pattern, its manufacturing method, device, and pattern forming method. Background technique [0002] 3C products refer to computer, communication and consumer electronic products, also known as information appliances electronic products. 3C products usually have patterns formed on the shell surface to improve the aesthetics of mobile phones, thereby attracting more consumers. [0003] At present, the pattern on the surface of the 3C product shell is usually formed by screen printing, water transfer printing, thermal transfer printing, pad printing, or IMD (In-Mole Decoration) technology. Pad printing is a printing method in which ink is printed on a preset surface by pressure through a pad printing head to form a pattern on the preset surface; water transfer is a printing method that transfers the pattern on the water transfer paper to the preset surface Printing technology; screen...
