In the present embodiment, a wearable electronic device is taken as an example for explanation, but the invention is not limited to the wearable electronic device, and in other embodiments, the alignment method of the invention may be other types of electronic devices suitable for the technical solution. Specifically, a wearable electronic device having a display function will be exemplified as a specific embodiment of the electronic device of the present invention.
Referring to fig. 1, fig. 1 is a schematic plan view of an electronic device 100 according to a first embodiment of the invention. In this embodiment, the electronic device 100 is a wearable electronic device with a display function, but is not limited thereto, and in other embodiments, the electronic device 100 may be other electronic devices. Specifically, in the present embodiment, the electronic device 100 is a smart watch, and the electronic device 100 includes a cover 1 and a display panel (not shown) for protecting other components inside the electronic device 100. The cover plate 1 may be of a suitable transparent material such as glass, plastic or the like. The display panel may be a liquid crystal display panel, an organic light emitting display panel, or the like, but is not limited thereto, and in this embodiment, the material of the cover plate 1 or the type of the display panel is not limited. In the present embodiment, the cover plate 1 is circular, but is not limited thereto, and in other embodiments, the cover plate 1 may be provided with other shapes, such as an oval or other polygonal shapes, as required. The cover plate 1 comprises a central area 101 and a peripheral area 102 surrounding the central area 101. In this embodiment, the display screen of the display panel is displayed through the central area 101. In other embodiments, the central region 101 may also be used to implement other functions, such as being an area for receiving touch sensing operations in an electronic device with touch sensing functionality.
Referring to fig. 1, 2 and 3 together, fig. 2 is a schematic cross-sectional view taken along line II-II of fig. 1, and fig. 3 is a schematic cross-sectional view taken along line III-III of fig. 1. For convenience of description, some elements of the electronic device 100, such as a display panel, a back panel, and the like, are omitted in fig. 2. The peripheral area 102 of the cover plate 1 is printed with multiple layers of ink. In the present embodiment, the peripheral area 102 is printed with a first ink layer 2, a second ink layer 3, a third ink layer 4 and a fourth ink layer 5 on the same surface 110 of the cover plate 1 through four printing processes, as shown in fig. 2. The surface 110 is a surface that is not exposed and does not contact the user during use. When in use, the user can observe the ink layer through the cover plate 1.
The first ink layer 2 is used as a base color of the peripheral area 102 of the cover plate 1, and the first ink layer 2 includes a first pattern 21 and a second pattern 22. As shown in fig. 1 and 2, in the present embodiment, the first pattern 21 and the second pattern 22 are concentric rings. The first pattern 21 has an inner diameter larger than that of the second pattern 22.
The second ink layer 3 includes a third pattern 31 as a decorative pattern and an alignment mark 32 for alignment. Preferably, there is sufficient space between the first pattern 21 and the second pattern 22 to print the third pattern 31. It is understood that the pattern formed by the first ink layer 2 is not limited to the first pattern 21 and the second pattern 22 being concentric rings, as long as the alignment marks 32 are shielded from being observed by the user from the front surface of the cover plate 1.
The third pattern 31 is formed between the first pattern 21 and the second pattern 22, and is annular. The third pattern 31 includes a plurality of sub-patterns 311 arranged at intervals, each sub-pattern 311 is provided with a hollow portion, the hollow portion has a shape of a desired pattern (such as LOGO or number), and the hollow portion is filled and covered by the third ink layer 4. The shape of the hollowed-out part can be designed according to a required pattern. In this embodiment, the third pattern 31 is directly formed on the surface 110 of the cover plate 1 and does not cover the first ink layer 2, so the third pattern 31 is not blocked by the first ink layer 2. In this embodiment, the third pattern 31 has 24 sub-patterns 311, and the patterns of the hollow portions on the sub-patterns 311 are numbers 1 to 24, respectively. The alignment mark 32 is used for aligning the cover plate with other components, such as a display panel (not shown), in a subsequent assembly process, so that a display area of the display panel corresponds to the central area 101, and a picture displayed by the display panel is not blocked by the ink in the peripheral area 102. The alignment mark 32 is formed on the surface of the first ink layer 2 away from the cover plate 1, and the alignment mark 32 is completely shielded by the first ink layer 2, so that the alignment mark 32 cannot be seen by a user when the electronic device 100 is viewed from the front side of the cover plate 1. In the present embodiment, the alignment mark 32 is formed on the first pattern 21 of the first ink layer 2, but is not limited thereto. In other embodiments, the alignment mark 32 may form the second pattern 22 of the first ink layer 2. The third pattern 31 and the alignment mark 32 can be formed simultaneously by the same printing process and the same layer of ink, thereby effectively reducing the error between the alignment mark and the third pattern. In this embodiment, in order not to affect the normal use of the alignment mark 32, the first ink layer 2 and the second ink layer 3 are different colors.
The third ink layer 4 is formed on the third pattern 31 of the second ink layer 3 to at least cover and fill the hollow portion of the third pattern 31, and the portion of the third ink layer 4 located at the hollow portion of the third pattern 31 forms a fourth pattern 411. In this embodiment, the third ink layer 4 forms a plurality of third ink sub-blocks 41 substantially covering each sub-pattern 311. Preferably, the third ink sub-block 41 is slightly smaller than the sub-pattern 311, so as to avoid the third ink sub-block 41 exceeding the boundary of the sub-pattern 311 due to the tolerance of the printing set. The hollowed-out portion of each sub-pattern 311 is filled with the third sub-ink block 41 to form the fourth pattern 411, and preferably, the color of the third ink layer 4 is different from the color of the second ink layer 3. In the present embodiment, the fourth pattern 411 has a shape of a number of 1 to 24, but is not limited thereto, and the fourth pattern 411 may be other desired patterns.
As shown in fig. 1, in the present embodiment, a gap 312 exposing the cap plate 1 is formed between adjacent sub-patterns 311. As shown in fig. 2, the fourth ink layer 5 is used as a light shielding layer to cover the portions of the first ink layer 2 and the second ink layer 3 that are not covered by the third ink layer 4 and to avoid (i.e. not cover) the alignment mark 32, i.e. the alignment mark 32 is not covered by the fourth ink layer 5 and is exposed, and is not shielded by the fourth ink layer 5. As shown in fig. 1, in this embodiment, the fourth ink layer 5 further covers (fills) the gaps 312 between the adjacent sub-patterns 311 to form the outer frame 51 of the fourth pattern. It should be noted that the gaps 312 between the sub-patterns 311 are not necessarily present, the gaps 312 between the sub-patterns 311 are formed according to design requirements, and in other embodiments, the gaps 312 between the sub-patterns 311 may not be formed when the outer frame 51 of the fourth pattern is not required to be formed. In this embodiment, the fourth ink layer 5 has a ring shape with a notch 52 (as shown in fig. 9), and the notch 52 corresponds to the alignment mark 32. As shown in fig. 3, the inner edge of the annular shape of the fourth ink layer 5 is flush with the inner edge of the second pattern 22 of the first ink layer 2; except for the notch 52 exposing the alignment mark 32, the outer edge of the fourth ink layer 5 is flush with the outer edge of the first pattern 21 of the first ink layer 2.
The alignment mark 32 and the third pattern 31 of the cover plate 1 according to the first embodiment of the present invention are formed simultaneously by the same printing process, so that the error between the alignment mark 32 and the third pattern 31 can be effectively reduced (i.e., ± 0.2 ° < error < ± 1 °), and after the fourth ink layer 5 (light shielding layer) is printed, the alignment mark 32 is not shielded, so that the alignment mark 32 can be applied to subsequent alignment with other components (e.g., display panel), thereby reducing the error between the cover plate 1 and other components.
Since the alignment mark 32 is completely shielded by the first ink layer 2 when viewed from the front surface of the cover plate 1, the alignment mark 32 is not shielded by the fourth ink layer 5 when viewed from the surface 110 of the cover plate during the assembly process of the electronic device 100, and therefore the assembly and alignment with other elements are not affected.
Referring to fig. 4, fig. 4 is a schematic plan view of an electronic device 200 according to a second embodiment of the invention. The structure of the electronic device 200 is substantially the same as that of the electronic device 100 of the first embodiment, and for convenience of description, the reference numerals of the first embodiment are used for the elements of the second embodiment having the same structure and function. In this embodiment, the second ink layer 3 includes a ring-shaped third pattern 31 as a decorative pattern and an alignment mark 32 for alignment. The third pattern 31 includes a plurality of sub-patterns 311, each sub-pattern 311 has a hollow portion, the hollow portion has a shape of a desired pattern (such as LOGO or number), and the hollow portion is filled and covered by the third ink layer 4. The shape of the hollowed-out part can be designed according to a required pattern. In this embodiment, the third pattern 31 is directly formed on the surface of the cover plate 1 and does not cover the first ink layer 2, so the third pattern 31 is not blocked by the first ink layer 2. In this embodiment, the patterns of the hollow portion include numbers 1 to 24, and the third pattern 31 may include a plurality of scale marks 6 corresponding to the numbers 1 to 24 in addition to the hollow numbers 1 to 24. In the present embodiment, each scale mark 6 is aligned with each outer frame 51, and each scale mark 6 is located on the extension line of the central axis of two adjacent numbers, but is not limited thereto. In other embodiments, the graduation mark 6 is not limited to be formed by the second ink layer 3, and may be formed by one of the first ink layer 2, the third ink layer 4, or the fourth ink layer 5. In this embodiment, the third ink layer 4 is formed on the third pattern 31 of the second ink layer 3 to at least cover the hollow portion of the third pattern 31. The third ink layer 4 forms a plurality of third ink sub-blocks 41 substantially covering each sub-pattern 311. Preferably, the third ink sub-block 41 is slightly smaller than the sub-pattern 311. Preferably, the third ink sub-block 41 is slightly smaller than the sub-pattern 311, so as to avoid the third ink sub-block 41 exceeding the boundary of the sub-pattern 311 due to the tolerance of the printing set. The hollowed-out portion of each sub-pattern 311 is filled with the third sub-ink block 41 to form the fourth pattern 411, and preferably, the color of the third ink layer 4 is different from the color of the second ink layer 3. In this way, the numbers (hollow portions) and the scale lines of the third pattern 31 do not need to be formed by two or more different printing processes, and can be formed together by the same printing process, thereby reducing the offset tolerance (< 0.1mm) between the numbers (hollow portions) and the scale lines.
Referring to fig. 5, fig. 5 is a schematic plan view of an electronic device 300 according to a third embodiment of the invention. The structure of the electronic device 300 is substantially the same as that of the electronic device of the first embodiment, and as such, the reference numerals of the first embodiment are used for the third embodiment for convenience of description. In this embodiment, the second ink layer 3 includes a third pattern 31 as a decorative pattern and an alignment mark 32 for alignment. The third pattern 31 includes a plurality of sub-patterns 311 arranged at intervals, and the sub-patterns 311 do not have a hollow portion, but are directly a desired pattern (e.g., a digital pattern). That is, the second ink layer 3 forms the required pattern (the third pattern 31) and the alignment mark 32 at the same time, so that the additional third ink layer 4 is not needed to cover the hollow portion of the second ink layer 3 to form the required pattern. Meanwhile, the third pattern 31 and the alignment mark 32 are simultaneously formed in the same printing process, and the position deviation between the third pattern 31 and the alignment mark 32 is reduced. In this case, after the second ink layer 3 is printed, the fourth ink layer 5 may be printed as a light-shielding layer without the third ink layer 4.
The method for manufacturing the electronic device of the present invention is described by taking a method for manufacturing the electronic device 100 of the first embodiment as an example.

The hollowed-out portion of each sub-pattern 311 is filled with the third sub-ink block 41 to form the fourth pattern 411, and preferably, the color of the third ink layer 4 is different from the color of the second ink layer 3.
Step four: as shown in fig. 9, a fourth ink layer 5 is printed as a light shielding layer, and the fourth ink layer 5 covers the first ink layer 2, the second ink layer 3, and the third ink layer 4 and avoids the alignment mark 32.
Specifically, the fourth ink layer has a gap 52 exposing the alignment mark 32; that is, the alignment mark 32 is not covered by the fourth ink layer 5 and is exposed, and is not shielded by the fourth ink layer 5.
In this embodiment, the fourth ink layer 5 covers the gap 312 between the adjacent sub-patterns 311 to form the outer frame 51 of the fourth pattern.
