[0021] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings.
[0022] Embodiment 1:
[0023] A cover plate for a wearable product, referring to Figure 1 and Figure 2 , including a cover body 10, the cover body 10 is made of glass. The cover body 10 is provided with a film layer structure 20 for special display, and the film layer structure 20 is provided with an information area 30 for displaying in a special environment, and the information area 30 is text or pattern.
[0024] Reference Figure 2 and Figure 3 The information area 30 is formed by coating a photoresist on the film structure 20 and then exposing and etching. The film structure 20 is completely etched away in areas other than the information area 30, so that the cover body 10 is not provided with the film structure 20 in positions other than the information area 30. Under normal circumstances, the cover body 10 has no difference in appearance and viewing angle from ordinary covers. When the wearable product is exposed to water, the information area 30 on the cover body 10 can be displayed to meet the needs of different use environments.
[0025] Reference Figure 3 The film layer structure 20 includes a plurality of high refractive layers 21 and low refractive layers 22 alternately arranged in sequence, and the high refractive layers 21 and the low refractive layers 22 are alternately stacked on the cover body 10 to form the film layer structure 20. The film layer structure 20 has at least three layers, and the high refractive layers 21 and the low refractive layers 22 are at least three layers alternately arranged on the cover body 10. Both the high refractive layers 21 and the low refractive layers 22 are film layers without absorptivity.
[0026] Further, refer to Figure 3 The material of the high refractive layer 21 is a high refractive index material, such as titanium oxide or niobium oxide. The material of the low refractive layer 22 is a low refractive index material, such as silicon oxide.
[0027] Further, refer to Figure 3 The thickness of each film layer of the film layer structure 20 is 3nm-500nm, that is, the thickness of the high refractive layer 21 and the low refractive layer 22 is 3nm-500nm. The thickness of the film layer structure 20 is 400nm-700nm.
[0028] Further, refer to Figure 3 When the cover body 10 is made of glass, the reflectivity of the film structure 20 is 4.2±2%.
[0029] Further, refer to Figure 3The high-refractive layer 21 and the low-refractive layer 22 in the film layer structure 20 are plated on the surface of the cover plate body 10 by evaporation or magnetron sputtering, and the information area 30 to be displayed is etched out by coating photoresist on the film layer structure 20 and exposing it to etching, and the other film layer structures 20 not containing the information area 30 are etched so that the film layer structure 20 is set at the position of the information area 30.
[0030] Reference Figure 1 and Figure 2 When the cover body 10 is made of glass, the single-side reflectivity is 4.2%. When the film structure 20 with no absorptivity is plated on the cover body 10, the reflectivity of the cover body 10 is still about 4.2%. Under normal circumstances, the human eye cannot recognize the difference in reflectivity between the cover body 10 and ordinary covers when the text or pattern prepared by the film structure 20 is used. However, when the cover body 10 is placed in water, the reflectivity of the film structure 20 changes sharply due to the change in the external environment it contacts, so that the human eye can see the content of the information area 30 on the cover body 10.
[0031] Embodiment 2:
[0032] The difference between this embodiment and the first embodiment is that the material of the cover body 10 is different.
[0033] Reference Figure 1 and Figure 2 The cover body 10 is made of ceramic. A film layer structure 20 is also disposed on the cover body 10 , and an information area 30 is disposed on the film layer structure 20 .
[0034] Reference Figure 1 and Figure 2 , when the material of the cover body 10 is ceramic, the reflectivity of the film structure 20 is 7±3%. When the cover body 10 is made of ceramic material, the single-sided reflectivity is about 7%. The film structure 20 with no absorptivity is plated on the cover body 10 so that the reflectivity of the cover body 10 is still about 7%. The text or pattern prepared by the film structure 20 cannot be recognized by the human eye under normal conditions as the difference in reflectivity between the cover body 10 and the ordinary cover. However, when the cover body 10 is placed in water, the reflectivity of the film structure 20 changes sharply due to the change in the external environment in contact with the film structure 20, so that the human eye can see the content of the information area 30 on the cover body 10.
[0035] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
