[0024] FIG. 1A to FIG. 1C are partial cross-sectional schematic views of part of a manufacturing method of an automotive ornament according to an embodiment of the disclosure.

[0025] Refer to FIG. 1A. In the embodiment, the manufacturing process of an automotive ornament 100 includes the following steps. First, a substrate 110 is provided. The substrate 110 has a first surface 110a and a second surface 110b opposite to the first surface 110a.

[0026] In some embodiments, the substrate 110 is, for example, polycarbonate (PC). However, the disclosure is not limited thereto. The substrate 110 may be any other suitable material, as long as the substrate 110 can carry the elements or film layers subsequently formed thereon and withstand subsequent manufacturing processes.

[0027] Refer to FIG. 1A. A texture layer 120 is formed on the substrate 110. For example, the texture layer 120 may be formed on the first surface 110a of the substrate 110. In the embodiment, the texture layer 120 is, for example, a black paint with a masking function formed by a spraying process, but the disclosure is not limited thereto. In other embodiments, the texture layer 120 may be formed using other materials and processes.

[0028] Refer to FIG. 1B. A texture pattern 122 is formed in the texture layer 120. For example, the texture pattern 122 may be formed in the texture layer 120 by laser engraving, but the disclosure is not limited thereto. As long as the texture layer 120 has the texture pattern 122, it falls within the protection scope of the disclosure. The texture pattern 122 is, for example, a plurality of openings on the texture layer 120 exposing the underlying substrate 110, as shown in FIG. 1B. However, the disclosure is not limited thereto, in not shown embodiments, the texture layer has no opening and the texture layer is a patterned texture layer, wherein the patterned texture layer is formed by blister molding or in-Mold Decoration (INS) molding, and the pattern is formed by printing. Moreover, a material of the patterned texture layer has a characteristic of transparency, so that the light can pass through the patterned texture layer even though the patterned texture layer without opening, therefore, the process of forming the opening can be omitted.

[0029] Refer to FIG. 1C. A transparent layer 130 is formed on the texture layer 120, wherein the transparent layer 130 has a characteristic of transparency. For example, the light transmittance of the transparent layer 130 is at least greater than 0%, but the disclosure is not limited thereto. The light transmittance may be adjusted according to actual design requirements.

[0030] Furthermore, the transparent layer 130 is stretched so that the transparent layer 130 extends from a top surface 120a of the texture layer 120 to cover a sidewall 120s of the texture layer 120 and a sidewall 110s of the substrate 110. The transparent layer 130 covers the texture pattern 122, and the texture layer 120 may have a degree of stretching less than that of the transparent layer 130. After the manufacturing process, the manufacturing of the automotive ornament 100 of the embodiment is substantially completed.

[0031] In the embodiment, the automotive ornament 100 is stretched by the transparent layer 130 to cover the top surface 120a and the sidewall 120s of the texture layer 120 and the sidewall 110s of the substrate 110, instead of combining the transparent layer and the texture layer and then to be stretched and to cover together. Therefore, the texture pattern 122 in the texture layer 120 is not offset or deformed due to the influence of the stretching force, so that problems such as the positioning and deformation of the texture pattern 122 are effectively improved.

[0032] Furthermore, the automotive ornament 100 may have advantages such as simplifying the manufacturing process, reducing manufacturing costs, improving manufacturing efficiency, manufacturing yield, processing efficiency, and processing yield. In addition, since the texture pattern 122 is covered by the transparent layer 130, the product surface have a dark decorative effect when the light source is not yet provided to the automotive ornament 100. When the light source is provided to the automotive ornament 100, due to the characteristics of the transparency of the transparent layer 130, the texture pattern 122 produces a decorative effect, which improves the diversity of the automotive ornament 100.

[0033] In some embodiments, the transparent layer 130 may not substantially stretch the texture layer 120 during the covering process. In other words, the degree of stretching of the texture layer 120 may be close to 0% during the covering process. However, the disclosure is not limited thereto.
