[0017] Figure 1A is an exploded view of the electronic device according to the first embodiment of this disclosure. Figure 1B is a top view of the first pattern layer of the electronic device of Figure 1A.

[0018] Referring to Figure 1, the electronic device 100 of this embodiment includes a first substrate 110, a first pattern layer 120, a second substrate 130, a second pattern layer 140, a third pattern layer 150, and an air gap G. The first substrate 110 has opposing first surfaces 111 and second surfaces 112. In this embodiment, the material of the first substrate 110 may be, for example, glass or other suitable transparent substrate materials, but is not limited thereto.

[0019] A first pattern layer 120 is disposed on a first surface 111 of a first substrate 110. The first pattern layer 120 includes a first grid region 121 and a second grid region 122. In the normal direction Z of the first substrate 110, the first grid region 121 connects to the second grid region 122 to cover or overlap a portion of the first surface 111 of the first substrate 110, but is not limited thereto. In some embodiments, the connected first grid region 121 and second grid region 122 may also cover or overlap the entire first surface 111 of the first substrate 110 in the normal direction Z of the first substrate 110.

[0020] Specifically, the first grid region 121 has a plurality of interconnected first grids A. Each first grid A has a plurality of grid lines A1 and a through-region A2. The grid lines A1 can be connected together and surround the through-region A2. The through-region A2 penetrates the first pattern layer 120 and exposes the first surface 111 of the first substrate 110. Furthermore, the second grid region 122 has a plurality of interconnected second grids B. Each second grid B has a plurality of grid lines B1 and a through-region B2. The grid lines B1 can be connected together and surround the through-region B2. The through-region B2 penetrates the first pattern layer 120 and exposes the first surface 111 of the first substrate 110.

[0021] In this embodiment, the shapes of the first grid A and the second grid B can be, for example, hollow rectangles formed by the intersection of four grid lines, but are not limited thereto. In some embodiments, the shapes of the first grid and the second grid can also be hollow triangles formed by the intersection of three grid lines, hollow hexagons formed by the intersection of six grid lines, or hollow polygons formed by the intersection of other numbers of grid lines.

[0022] In this embodiment, since the linewidth of the grid lines A1 constituting the first grid A can be substantially the same as (or similar to) the linewidth of the grid lines B1 constituting the second grid B, and the shape, area, and reflectivity of the first grid A can be substantially the same as (or similar to) the shape, area, and reflectivity of the second grid B, the transmittance of the first grid A can be substantially the same as (or similar to) the transmittance of the second grid B. In some embodiments, the difference between the transmittance of the first grid A and the transmittance of the second grid B can be, for example, less than 5%, but is not limited thereto. The transmittance can be simulated from the material, shape, area, etc., of the first and second grids, or determined by actual measurement.

[0023] In this embodiment, the material of the first grid A in the first grid region 121 can be an opaque non-metallic material with low loss tangent (Df), so that the first grid A can be a non-metallic grid, but it is not limited thereto. The material of the second grid B in the second grid region 122 can be an opaque metallic material, so that the second grid B can be a metallic grid, but it is not limited thereto. For example, the material of the second grid B may include copper, aluminum, silver, alloys of the aforementioned materials, or other opaque conductive materials. In other embodiments, the material of the first grid A in the first grid region 121 can be an opaque metallic material, so that the first grid A can be a metallic grid, and the material of the second grid B can be an opaque non-metallic material with low loss tangent (Df), so that the second grid B can be a non-metallic grid. In some embodiments, the material of the second grid B in the second grid area 122 can be an opaque metal grid covering a low-loss tangent (Df) non-metallic grid. In this embodiment, the method for forming the first pattern layer is to first form a low-loss tangent (Df) material on a first substrate, then pattern it to form a grid, and then form an opaque metal layer on the low-loss tangent (Df) grid, and pattern the opaque metal layer so that the grid is located on a portion of the non-metallic grid. Furthermore, compared to electronic devices that generally suffer from poor aesthetics due to only one type of grid area in the first pattern layer, resulting in dark patterns (e.g., concentric circle patterns), the electronic device 100 of this embodiment can reduce poor aesthetics such as dark patterns (e.g., concentric circle patterns) by designing the first pattern layer 120 to include interconnected first grid areas 121 and second grid areas 122, thereby improving the aesthetics of the electronic device 100.

[0024] The second substrate 130 is disposed opposite to the first substrate 110. The second substrate 130 has a third surface 131 and a fourth surface 132 facing each other, and the third surface 131 faces the second surface 112. In this embodiment, the material of the second substrate 130 may be, for example, glass or other suitable transparent substrate material, but is not limited thereto.

[0025] The second pattern layer 140 is disposed on the third surface 131 of the second substrate 130. The second pattern layer 140 has a grid area 141, and the grid area 141 can cover a portion of the third surface 131 of the second substrate 130, but is not limited thereto. That is, the grid area 141 of the second pattern layer 140 does not completely cover the third surface 131 of the second substrate 130.

[0026] A third pattern layer 150 is disposed on the fourth surface 132 of the second substrate 130. The third pattern layer 150 has a grid area 151, and the grid area 151 can cover a portion of the fourth surface 132 of the second substrate 130, but is not limited thereto. That is, the grid area 151 of the third pattern layer 150 does not completely cover the fourth surface 132 of the second substrate 130.

[0027] An air gap G is provided between the second surface 112 of the first substrate 110 and the second pattern layer 140. That is, the second surface 112 of the first substrate 110 does not contact the second pattern layer 140.

[0028] The electronic device 100 of this embodiment can be applied to an antenna device or a transparent antenna device for collecting signals, amplifying signals, and / or transmitting signals.

[0029] In this embodiment, the first pattern layer 120 is designed as a full-surface grid to improve the inconsistent transmittance of the entire surface or reduce visual dark patterns (such as concentric circle patterns), but it is not limited thereto. In some embodiments, at least one, at least two, or all of the pattern layers of the first pattern layer, the second pattern layer, and the third pattern layer may be designed as a full-surface grid to reduce visual dark patterns (such as concentric circle patterns) and thus improve the appearance.

[0030] In the electronic device 100 of this embodiment, two substrates and three pattern layers are schematically shown, but this disclosure does not limit the number of substrates and pattern layers in the electronic device. In some embodiments, other numbers of substrates and / or pattern layers may be provided between the first substrate 110 and the second substrate 130 of the electronic device 100, depending on actual needs or design.

[0031] In the electronic device 100 of this embodiment, although an opaque metallic material is used to fabricate the second grid B of the second grid area 122 for signal transmission purposes, this disclosure is not limited thereto. In some embodiments not shown, the second grid of the second grid area may also be made of a non-metallic material, and an opaque metallic material may be used to fabricate a fourth pattern layer for signal transmission; wherein the fourth pattern layer is disposed on the third pattern layer, and the fourth pattern layer has a third grid area that can overlap with the second grid area.

[0032] Other embodiments will be listed below for illustration. It must be noted that the following embodiments use the component reference numerals and some content from the foregoing embodiments, with the same reference numerals representing the same or similar components, and descriptions of identical technical content omitted. For explanations of the omitted parts, please refer to the foregoing embodiments; these will not be repeated in the following embodiments.

[0033] Figure 2 is a partial top view of the first pattern layer of the electronic device according to the second embodiment of this disclosure. Referring to Figures 1B and 2 simultaneously, the electronic device 100a of this embodiment is similar to the electronic device 100 in Figure 1B, except that: in the first pattern layer 120a of the electronic device 100a in this embodiment, the first grid area 121a may include a first area 1211 and a second area 1218, and the transmittance of the first area 1211 may be different from the transmittance of the second area 1218.

[0034] Specifically, referring to Figure 2, in this embodiment, since the line width W1 of the grid line A1a of the first grid Aa in the first region 1211 can be greater than the line width W2 of the grid line A1 of the first grid A in the second region 1218, the area of ​​the penetration area A2a of the first grid Aa is smaller than the area of ​​the penetration area A2 of the first grid A, thereby making the transmittance of the first region 1211 less than the transmittance of the second region 1218 (or the brightness of the first region 1211 less than the brightness of the second region 1218). With this design, the circular pattern of the first region 1211 of the first grid region 121a of the first pattern layer 120a can be presented, and the appearance of the electronic device 100a can be richer and less monotonous.

[0035] Although the electronic device 100a of this embodiment exemplifies adjusting the transmittance (or brightness) of different regions and enriching the pattern of the first pattern layer 120a by adjusting the line width of the grid lines in different regions of the first grid region 121a, this disclosure is not limited thereto. In some embodiments, the transmittance (or brightness) of different regions can also be adjusted by adjusting the line width of the grid lines in different regions of the second grid region 122 (or by simultaneously adjusting the line width of the grid lines in the first grid region 121a and the second grid region 122), thereby enriching the pattern of the first pattern layer.

[0036] In the electronic device 100a of this embodiment, although the pattern of the first region 1211 is a circular pattern, this disclosure does not limit the pattern of the first region 1211. That is, in some embodiments, the pattern of the first region 1211 can also be other regular or irregular patterns, as long as the transmittance or brightness of the first region 1211 is less than the transmittance or brightness of the second region 1218, and the pattern of the first region 1211 is displayed.

[0037] Figure 3 is a partial top view of the first pattern layer of the electronic device according to the third embodiment of this disclosure. Referring to Figures 1B and 3 simultaneously, the electronic device 100b of this embodiment is similar to the electronic device 100 in Figure 1B, except that: in the first pattern layer 120b of the electronic device 100b in this embodiment, the first grid area 121b may include a first area 1211 and a second area 1218, and the transmittance of the first area 1211 is different from the transmittance of the second area 1218.

[0038] Specifically, referring to Figure 3, in this embodiment, since the area enclosed by the outline of the first grid Ab in the first region 1211 can be smaller than the area enclosed by the outline of the first grid A in the second region 1218 (or, in a unit area UA, the number of first grids Ab in the first region 1211 can be greater than the number of first grids A in the second region 1218), the area of ​​the penetration area A2b of the first grid Ab is smaller than the area of ​​the penetration area A2 of the first grid A, thereby making the transmittance of the first region 1211 less than the transmittance of the second region 1218 (or the brightness of the first region 1211 less than the brightness of the second region 1218). With this design, the circular pattern of the first region 1211 of the first grid region 121b of the first pattern layer 120b can be presented, and the appearance of the electronic device 100b can be richer and less monotonous.

[0039] Although the electronic device 100b of this embodiment exemplifies adjusting the transmittance (or brightness) of different regions and enriching the pattern of the first pattern layer 120b by adjusting the area enclosed by the outlines of the grids in different regions of the first grid region 121b, this disclosure is not limited thereto. In some embodiments, the transmittance of different regions can also be adjusted by adjusting the area enclosed by the outlines of the grids in different regions of the second grid region 122 (or by simultaneously adjusting the areas enclosed by the outlines of the grids in the first grid region 121b and the second grid region 122), thereby enriching the pattern of the first pattern layer.

[0040] In the electronic device 100b of this embodiment, although the pattern of the first region 1211 is a circular pattern, this disclosure does not limit the pattern of the first region 1211. That is, in some embodiments, the pattern of the first region 1211 can also be other regular or irregular patterns, as long as the transmittance or brightness of the first region 1211 is less than the transmittance or brightness of the second region 1218, and the pattern of the first region 1211 is displayed.

[0041] Figure 4 is a partial top view of the first pattern layer of the electronic device according to the fourth embodiment of this disclosure. Referring to Figures 1B and 4 simultaneously, the electronic device 100c of this embodiment is similar to the electronic device 100 in Figure 1B, except that: in the first pattern layer 120c of the electronic device 100c of this embodiment, the first grid area 121c may include a first area 1211 and a second area 1218, and the transmittance of the first area 1211 is different from the transmittance of the second area 1218.

[0042] Specifically, referring to Figure 4, in this embodiment, the first grid Ac in the first region 1211 is a hollow hexagon, and the first grid A in the second region 1218 is a hollow quadrilateral.

[0043] In this embodiment, since the shape of the first grid Ac in the first region 1211 is different from the shape of the first grid A in the second region 1218, and the area of ​​the through area A2c of the first grid Ac is smaller than the area of ​​the through area A2 of the first grid A (or, in a unit area UA, the number of first grids Ac in the first region 1211 is greater than the number of first grids A in the second region 1218), the transmittance of the first region 1211 is less than the transmittance of the second region 1218 (or the brightness of the first region 1211 is less than the brightness of the second region 1218). This design allows the circular pattern of the first grid region 1211 of the first pattern layer 120c to be presented, and makes the appearance of the electronic device 100c more varied and less monotonous.

[0044] While the electronic device 100c of this embodiment exemplifies adjusting the transmittance (or brightness) of different regions and enriching the pattern of the first pattern layer 120c by adjusting the shape of the grids in different regions of the first grid region 121c, this disclosure is not limited thereto. In some embodiments, the transmittance of different regions can also be adjusted by adjusting the shape of the grids in different regions of the second grid region 122 (or by simultaneously adjusting the shape of the grids in the first grid region 121c and the second grid region 122), thereby enriching the pattern of the first pattern layer.

[0045] In the electronic device 100c of this embodiment, although the pattern of the first region 1211 is a circular pattern, this disclosure does not limit the pattern of the first region 1211. That is, in some embodiments, the pattern of the first region 1211 can also be other regular or irregular patterns, as long as the transmittance or brightness of the first region 1211 is less than the transmittance or brightness of the second region 1218, and the pattern of the first region 1211 is displayed.

[0046] Figure 5A is an exploded view of the electronic device according to the fifth embodiment of this disclosure. Figure 5B is a top view of the first pattern layer and the fourth pattern layer of the electronic device of Figure 5A. Referring simultaneously to Figures 1A to 1B and Figures 5A to 5B, the electronic device 100d of this embodiment is similar to the electronic device 100 in Figures 1A to 1B, except that the electronic device 100d of this embodiment further includes a fourth pattern layer 160.

[0047] Specifically, referring to Figures 5A and 5B, in this embodiment, a fourth pattern layer 160 is disposed on the first pattern layer 120, and the fourth pattern layer 160 can cover (or overlap) a portion of the first pattern layer 120 in the normal direction Z of the first substrate 110. The fourth pattern layer 160 includes a third grid area 161, and the third grid area 161 can overlap corresponding portions of the first grid area 121 and the second grid area 122. The third grid area 161 has multiple interconnected third grids (not shown), and each third grid has multiple grid lines and through areas.

[0048] In this embodiment, in order to present the circular pattern of the third grid area 161 and make the appearance of the electronic device 100d more varied and less monotonous, the transmittance of the third grid area 161 can be made less than that of the first grid area 121, for example, in a manner similar to that in Figures 2, 3 and / or 4, but not limited to this. For example, the line width of the grid line of the third grid in the third grid area 161 is less than the line width of the grid line A1 of the first grid A in the first grid area 121; the area enclosed by the outline of the third grid in the third grid area 161 is less than the area enclosed by the outline of the first grid A in the first grid area 121; or the shape of the third grid in the third grid area 161 is different from the shape of the first grid A in the first grid area 121, and the area of ​​the penetrating area of ​​the third grid is less than the area of ​​the penetrating area A2 of the first grid A.

[0049] In some embodiments, by altering the reflectivity of the third grid region 161, making its reflectivity lower than that of the first grid region 121, the circular pattern of the third grid region 161 can be presented, thereby enriching the appearance of the electronic device 100d and preventing it from becoming monotonous. The reflectivity can be simulated using the material, shape, and area of ​​the first and second grids, or determined through actual measurement.

[0050] In the electronic device 100d of this embodiment, although the pattern of the third grid area 161 is a circular pattern, this disclosure does not limit the pattern of the third grid area 161. That is, in some embodiments, the pattern of the third grid area 161 can also be other regular or irregular patterns, as long as the transmittance, brightness or reflectance of the third grid area 161 is less than the transmittance, brightness or reflectance of the second area 1218, and the pattern of the third grid area 161 can be presented.

[0051] Figure 6 is a partial top view of the first pattern layer of the electronic device according to the sixth embodiment of this disclosure. Referring to Figures 1B and 6 simultaneously, the electronic device 100e of this embodiment is similar to the electronic device 100 in Figure 1B, except that: in the first pattern layer 120e of the electronic device 100e in this embodiment, the first grid area 121e may include a first area 1211, a third area 1212, a fourth area 1213, a fifth area 1214, a sixth area 1215, and a second area 1218.

[0052] Specifically, referring to Figure 6, in this embodiment, the first grid area 121e can be designed to represent a pattern of a cat's face, but is not limited thereto. Specifically, the first area 1211 can represent the cat's eyes, the third area 1212 can represent the cat's nose, the fourth area 1213 can represent the cat's left ear, the fifth area 1214 can represent the cat's mouth, the sixth area 1215 can represent a patch adjacent to the cat's right ear, and the second area 1218 can represent the rest of the cat's face.

[0053] In this embodiment, the transmittance of the first region 1211, the third region 1212, the fourth region 1213, the fifth region 1214, and the sixth region 1215 can be changed in a manner similar to Figures 2, 3, 4, or a combination thereof, so that the first region 1211, the third region 1212, the fourth region 1213, the fifth region 1214, the sixth region 1215, and the second region 1218 can each have different transmittance or brightness, thereby allowing the patterns of the first region 1211, the third region 1212, the fourth region 1213, the fifth region 1214, the sixth region 1215, and the second region 1218 to be displayed, and the first grid area 121e of the first pattern layer 120e of the electronic device 100e can display a cat face pattern.

[0054] In some embodiments, in addition to changing the transmittance of different regions in the first grid region 121e, the reflectance (or brightness) of different regions can also be changed by changing the reflective properties of different regions, thereby allowing the patterns of different regions to be presented.

[0055] In summary, in the electronic device of this disclosed embodiment, the design of the first pattern layer including a first grid area and a second grid area connected to each other reduces the problem of poor aesthetics such as dark patterns (e.g., concentric circle patterns), thereby improving the aesthetics of the electronic device. In some embodiments of the electronic device, the transmittance (or brightness) of different areas is adjusted by adjusting the line width of the grid lines (or the area enclosed by the grid outline or the shape of the grid) of different areas in the grid area of ​​the first pattern layer (e.g., the first grid area and / or the second grid area), or by adjusting the reflectivity (or brightness) of different areas in the grid area of ​​the first pattern layer (e.g., the first grid area and / or the second grid area), so that the patterns of different areas can be presented, thereby making the aesthetics of the electronic device richer and less monotonous.

Anyone skilled in the art may make some modifications and refinements without departing from the spirit and scope of this disclosure. Therefore, the scope of protection of this disclosure shall be determined by the appended claims.
