Abstract
Description
Technical Field
[0001] The present invention relates to an electronic device, and more particularly to an electronic device having a metal mesh with low visibility. Background Art
[0002] With the evolution and development of electronic devices, electronic devices have become indispensable items in today's society. In order to endow an electronic device with sensing functions (for example, touch sensing functions), the electronic device may include a metal mesh having a plurality of electrodes for sensing through the electrodes. However, since there are a plurality of break points in the metal mesh (for example, the break points are used to separate the electrodes), the aperture ratio of the unit area having break points is different from the aperture ratio of the unit area without break points, so that the visibility of the metal mesh is increased, thereby reducing the viewing quality of the electronic device (users are likely to perceive the existence of the metal mesh). Accordingly, the industry nowadays is committed to reducing the visibility of the metal mesh. Summary of the Invention
[0003] Therefore, the main object of the present invention is to provide an electronic device having a metal mesh, wherein the metal mesh includes compensation line segments to compensate for the break points, thereby reducing the visibility of the metal mesh.
[0004] An embodiment of the present invention provides an electronic device, including a substrate and a first conductive layer. The first conductive layer is disposed on the substrate. The first conductive layer includes a first metal mesh. The first metal mesh includes a first metal line segment, a second metal line segment, and a first compensation metal line segment. The first metal line segment extends along a first direction, and the first metal line segment has a first end point. The second metal line segment extends along the first direction, and the second metal line segment has a second end point. The first metal line segment and the second metal line segment are separated from each other. A first imaginary line extending along the first direction passes through the first end point and the second end point, and a portion of the first imaginary line between the first end point and the second end point is defined as a first break point. The first compensation metal line segment is separated from and electrically insulated from the first metal line segment and the second metal line segment. The first compensation metal line segment does not completely overlap the first break point. The first compensation metal line segment has two first line segment end points, and the shortest distance between each first line segment end point and the first break point is less than or equal to 50 micrometers (μm).
[0005] In the present invention, since the compensation metal line segment is adjacent to and does not completely overlap the break point, the adverse visual effect caused by the break point can be compensated or reduced. Moreover, since the compensation metal line segment and the metal line segment beside the break point belong to the same conductive layer, the manufacturing cost of the metal mesh having the compensation metal line segment can be reduced.

[0046] To enable those skilled in the art to further understand the present invention, the following will detail the embodiments of the present invention, the typical materials or parameter ranges of key components, and explain the composition and desired effects of the present invention in conjunction with the marked drawings. It should be noted that the drawings are all simplified schematic diagrams, and based on the current technology, the material and parameter ranges of key components are illustrated. Therefore, only the components and combination relationships related to the present invention are shown to provide a clearer description of the basic structure, implementation method or operation of the present invention. The actual components and layouts may be more complex, and the material or parameter ranges used may change with the development of future technologies. In addition, for convenience of description, the components shown in the drawings of the present invention may not be drawn in equal proportion according to the actual number, shape, size, and their details can be adjusted according to the design requirements.
[0047] In the following description and claims of the patent application, words such as "comprising", "including", "having", etc. are open-ended terms, and thus should be construed as meaning "including but not limited to...". Therefore, when the terms "comprising", "including", and / or "having" are used in the description of the present invention, they specify the presence of corresponding features, regions, steps, operations, and / or components, but do not exclude the presence of one or more corresponding features, regions, steps, operations, and / or components.
[0048] It should be noted that in the description and claims of the patent application, the term "horizontal direction" refers to the direction parallel to directions X and Y in the drawings, the term "vertical direction" refers to the direction parallel to direction Z in the drawings, and the term "top view" refers to the viewing result along the vertical direction.
[0049] It should be noted that in the description and claims of the patent application, the term "overlap" means the overlap of two components in the Z direction, and in the case where it is not specified, the term "overlap" can be partial overlap or complete overlap. It should be noted that the term "incomplete overlap" can be partial overlap or complete non - overlap, that is, when "Component C1 does not completely overlap Component D1", at least a part of Component C1 does not overlap with Component D1.
[0050] It should be noted that in the description and claims, the term "parallel" means that the included angle between two components can be less than or equal to a specific angle, such as 3 degrees or 1 degree.

They do not themselves imply or represent that the (or these) elements have any previous ordinal numbers, nor do they represent the order of one element and another element, or the order in the manufacturing method. The use of these ordinal numbers is only to clearly distinguish an element with a certain name from another element with the same name. The claims and the description may not use the same terms. Accordingly, the first component in the description may be the second component in the claims.
[0052] It should be noted that in the following examples, without departing from the spirit of the present invention, the features in several different examples can be replaced, reorganized, and mixed to complete other examples. As long as the features between the examples do not violate the spirit of the invention or conflict with each other, they can be arbitrarily mixed and used.
[0053] In the present invention, the type of the electronic device is not particularly limited and can have any suitable functions. For example, the electronic device may include a display function and / or a sensing function according to requirements, but is not limited thereto. In addition, the shape of the electronic device can be polygonal (such as a rectangle), a shape with a curved edge (such as a circle), or other suitable shapes, but is not limited thereto.
[0054] For example, the electronic device may be a touch display for performing screen display and touch sensing, where the touch display may be a color display or a monochrome display. The touch display may include a plurality of pixels, and each pixel may include at least one sub-pixel. The number of sub-pixels included in a pixel and the color of the light generated by the sub-pixels may be designed according to requirements.
[0055] In the present invention, the line widths of the metal wire, the metal line segment, and the compensation metal line segment may be designed according to requirements. In the drawings of the present invention, for the sake of clarity of the drawings, the line width of the compensation metal line segment in the drawings is greater than the line widths of the metal wire and the metal line segment, but the line width design of the present invention is not limited thereto.
[0056] Please refer to Figures 1 to 3 , Figure 1 which shows a top view schematic diagram of the first conductive layer of the electronic device according to the first embodiment of the present invention. Figure 2 As shown in Figure 1 an enlarged schematic diagram of the region R of Figure 3 which shows a cross-sectional schematic diagram of the electronic device 100 according to the first embodiment of the present invention. As Figures 1 to 3 shown, the electronic device 100 may include a substrate 110, and various components in the electronic device 100 may be disposed on the substrate 110. The substrate 110 may include glass, quartz, sapphire, polyimide (PI), polyethylene terephthalate (PET), other suitable materials, or a combination thereof to serve as a flexible or rigid substrate, but is not limited thereto.
[0057] The electronic device 100 may include at least one conductive layer disposed on the substrate 110. Examples of the material of the conductive layer may include metal, transparent conductive materials (such as indium tin oxide (ITO), indium zinc oxide (IZO), etc.), other suitable conductive materials, or a combination thereof. In the present invention, as Figures 1 to 3 shown, the conductive layer included in the electronic device 100 may include a first conductive layer 120.
[0058] The first conductive layer 120 may include a first metal grid 122 containing a plurality of metal grid units MU for performing sensing (e.g., touch sensing), where the first metal grid 122 may be any suitable type of sensor (such as a capacitive sensor). In the present invention, the shape of the metal grid unit MU may be designed according to requirements. For example, in Figure 1 and Figure 2Among them, the first metal grid 122 may include a plurality of metal lines 122a extending along the first direction D1 and a plurality of metal lines 122b extending along the second direction D2 to form a parallelogram metal grid unit MU, but not limited thereto.
[0059] It should be noted that the first direction D1 and the second direction D2 are perpendicular to the direction Z and are not parallel to each other, and the angular relationship between the first direction D1, the second direction D2 and the direction X can be designed according to requirements. For example, as Figure 1 shown, the first direction D1 may not be perpendicular to the second direction D2, and neither the first direction D1 nor the second direction D2 is parallel and not perpendicular to the direction X, but not limited thereto. For another example (not shown in the figure), the first direction D1 may be parallel to the direction X, but not limited thereto. For another example (not shown in the figure), the first direction D1 may be perpendicular to the second direction D2, but not limited thereto.
[0060] In Figure 1 Among them, the first metal grid 122 may include a plurality of first grid electrodes 124 and a plurality of second grid electrodes 126, and the first grid electrodes 124 and the second grid electrodes 126 are separated from each other. For example, the first metal grid 122 and the second grid electrodes 126 are alternately arranged in the direction X, and the long directions of the first grid electrodes 124 and the second grid electrodes 126 are parallel to the direction Y, but not limited thereto. In some embodiments, both the first grid electrodes 124 and the second grid electrodes 126 may be sensing electrodes for sensing, but not limited thereto. In some embodiments, the first grid electrodes 124 may be sensing electrodes for sensing, and the second grid electrodes 126 may be dummy electrodes, but not limited thereto.
[0061] In Figure 1 and Figure 2 Among them, the first metal grid 122 may have at least one break point portion, so that the first grid electrodes 124 and the second grid electrodes 126 can be separated from each other through the break point portion, where Figure 1Some of the metal mesh units MU shown have break points (for the sake of clearer description below, the metal mesh unit MU without break points is called "metal mesh unit MU1", and the metal mesh unit MU with break points is called "metal mesh unit MU2"). Specifically, the metal mesh unit MU2 may include a first metal line segment S1 and a second metal line segment S2. The first metal line segment S1 is included in the first grid electrode 124, and the second metal line segment S2 is included in the second grid electrode 126. The first metal line segment S1 and the second metal line segment S2 are separated from each other and both extend along the first direction D1 (the first metal line segment S1 and the second metal line segment S2 can be regarded as a part of the metal wire 122a). The first metal line segment S1 has a first end point E1, the second metal line segment S2 has a second end point E2, and a first break point CP1 exists between the first end point E1 of the first metal line segment S1 and the second end point E2 of the second metal line segment S2. More precisely, Figure 2 A first imaginary line AL1 extending along the first direction D1 is shown. The first imaginary line AL1 passes through the first end point E1 and the second end point E2, and the part of the first imaginary line AL1 between the first end point E1 and the second end point E2 is defined as the first break point CP1.
[0062] Optionally, in Figure 1 and Figure 2 the metal mesh unit MU2 may include a third metal line segment S3 and a fourth metal line segment S4. The third metal line segment S3 is included in the first grid electrode 124, and the fourth metal line segment S4 is included in the second grid electrode 126. The third metal line segment S3 and the fourth metal line segment S4 are separated from each other and both extend along the second direction D2 (the third metal line segment S3 and the fourth metal line segment S4 can be regarded as a part of the metal wire 122b). The third metal line segment S3 has a third end point E3, the fourth metal line segment S4 has a fourth end point E4, and a second break point CP2 exists between the third end point E3 of the third metal line segment S3 and the fourth end point E4 of the fourth metal line segment S4. More precisely, Figure 2 A second imaginary line AL2 extending along the second direction D2 is shown. The second imaginary line AL2 passes through the third end point E3 and the fourth end point E4, and the part of the second imaginary line AL2 between the third end point E3 and the fourth end point E4 is defined as the second break point CP2.
[0063] Due to the existence of the break point, the visual effect of the metal mesh unit MU2 is different from that of the metal mesh unit MU1, which will cause the first metal mesh 122 to be easily noticed by the user and affect the viewing quality. Therefore, in Figure 1 and Figure 2Among them, the first metal grid 122 includes at least one compensating metal line segment to compensate for or reduce the poor visual effect caused by the break point portion. In some embodiments, the compensating metal line segment may be, for example, a straight line segment, but is not limited thereto.
[0064] Specifically, the first metal grid 122 may include a first compensating metal line segment 128a for compensating for or reducing the poor visual effect caused by the first break point portion CP1. In the present invention, since the first compensating metal line segment 128a and the first metal line segment S1 and the second metal line segment S2 located on both sides of the first break point portion CP1 all belong to the structure of the first conductive layer 120, therefore, in order to enable the first compensating metal line segment 128a to compensate for or reduce the poor visual effect caused by the first break point portion CP1, and at the same time make the first compensating metal line segment 128a electrically insulated from the first metal line segment S1 and the second metal line segment S2, in Figure 1 and Figure 2 Among them, the first compensating metal line segment 128a does not completely overlap (i.e., partially overlaps or does not overlap at all) with the first break point portion CP1, and the first compensating metal line segment 128a is separated from the first metal line segment S1 and the second metal line segment S2.
[0065] In the present invention, the first compensating metal line segment 128a needs to be adjacent to the first break point portion CP1 to compensate for or reduce the poor visual effect caused by the first break point portion CP1. In some embodiments, the first compensating metal line segment 128a may have two first line segment endpoints 128ae, and the shortest distance between each first line segment endpoint 128ae and the first break point portion CP1 may be less than or equal to 50 micrometers (μm) or may be less than or equal to 15 micrometers, but is not limited thereto. In some embodiments, the shortest distance between any part of the first compensating metal line segment 128a and the first break point portion CP1 may be less than or equal to 50 micrometers or may be less than or equal to 15 micrometers, but is not limited thereto. With this distance design, the first compensating metal line segment 128a can compensate for or reduce the poor visual effect caused by the first break point portion CP1, and can reduce the possibility of the first compensating metal line segment 128a being detected by the user. It should be noted that if the distance between the first compensating metal line segment 128a and the first break point portion CP1 is greater than 50 micrometers, the first compensating metal line segment 128a will lose its compensation function, and the first compensating metal line segment 128a will be easily detected by the user and affect the viewing quality.
[0066] In the present invention, the relationship between the first compensating metal line segment 128a and the first break point portion CP1 (i.e., the first compensating metal line segment 128a does not completely overlap with the first break point portion CP1) can be designed according to requirements. In some embodiments (such as Figure 1 and Figure 2 ), the first compensating metal line segment 128a does not overlap with the first break point portion CP1 at all. For example, inFigure 1 In Figure 2 , the first compensating metal line segment 128a may be parallel to the first direction D1, such that the first compensating metal line segment 128a may be parallel to the first metal line segment S1, the second metal line segment S2, and the first imaginary line AL1, but not limited thereto. In Figure 1 and Figure 2 , a first distance DS1 may exist between the first compensating metal line segment 128a and the first break point portion CP1, such that the first compensating metal line segment 128a does not overlap the first break point portion CP1 at all. For example, the first distance DS1 may be greater than or equal to 3 micrometers and less than or equal to 50 micrometers, or may be greater than or equal to 3 micrometers and less than or equal to 15 micrometers, but not limited thereto. It should be noted that if the distance between the first compensating metal line segment 128a and the first break point portion CP1 is less than 3 micrometers, the first compensating metal line segment 128a may be connected to the first metal line segment S1 and / or the second metal line segment S2 due to process defects or process errors (such as incomplete etching process), resulting in the failure of the design of the first break point portion CP1.
[0067] In some embodiments (such as Figure 1 and Figure 2 ), the angle between the line connecting the midpoints of the first compensating metal line segment 128a and the first break point portion CP1 and the first direction D1 may be greater than or equal to 80 degrees and less than or equal to 100 degrees, but not limited thereto. According to this design, the offset of the first compensating metal line segment 128a along the first direction D1 with respect to the first break point portion CP1 can be reduced.
[0068] In the present invention, the length of the first compensation metal line segment 128a can be designed according to requirements, and there can be a correlation between the length of the first compensation metal line segment 128a and the length of the first break point portion CP1. In some embodiments, the ratio of the length of the first compensation metal line segment 128a to the length of the first break point portion CP1 can be greater than or equal to 0.7 and less than or equal to 1.3, but is not limited thereto. In some embodiments, the length of the first compensation metal line segment 128a can be greater than or equal to 10 micrometers and less than or equal to 60 micrometers, but is not limited thereto. In some embodiments, the difference between the length of the first compensation metal line segment 128a and the length of the first break point portion CP1 can be less than or equal to 4 micrometers, but is not limited thereto. It should be noted that if the difference between the length of the first compensation metal line segment 128a and the length of the first break point portion CP1 is too large (for example, the ratio of the length of the first compensation metal line segment 128a to the length of the first break point portion CP1 is less than 0.7 or greater than 1.3, or the difference between the length of the first compensation metal line segment 128a and the length of the first break point portion CP1 is greater than 4 micrometers), then the first compensation metal line segment 128a is likely to be perceived by the user and affect the viewing quality, causing the first compensation metal line segment 128a to lose its compensation function. For example, when the length of the first break point portion CP1 is 10 micrometers, the length of the first compensation metal line segment 128a can be 7 micrometers to 13 micrometers, but is not limited thereto.
[0069] Similarly, the first metal grid 122 can include a second compensation metal line segment 128b for compensating or reducing the adverse visual effect caused by the second break point portion CP2. In Figure 1 With Figure 2 In, the second compensation metal line segment 128b does not completely overlap (i.e., partially overlaps or does not overlap at all) with the second break point portion CP2, and the second compensation metal line segment 128b is separated and electrically insulated from the third metal line segment S3 and the fourth metal line segment S4.
[0070] In the present invention, the second compensation metal line segment 128b needs to be adjacent to the second break point portion CP2 to compensate or reduce the adverse visual effect caused by the second break point portion CP2. In some embodiments, the second compensation metal line segment 128b can have two second line segment endpoints 128be, and the shortest distance between each second line segment endpoint 128be and the second break point portion CP2 can be less than or equal to 50 micrometers or can be less than or equal to 15 micrometers, but is not limited thereto. In some embodiments, the shortest distance between any part of the second compensation metal line segment 128b and the second break point portion CP2 can be less than or equal to 50 micrometers or can be less than or equal to 15 micrometers, but is not limited thereto.
[0071] The setting of the second compensation metal line segment 128b can be similar to that of the first compensation metal line segment 128a. In some embodiments (such as Figure 1 With Figure 2), the second compensation metal line segment 128b does not overlap with the second break point portion CP2 at all. For example, in Figure 1 and Figure 2 , the second compensation metal line segment 128b may be parallel to the second direction D2, such that the second compensation metal line segment 128b may be parallel to the third metal line segment S3, the fourth metal line segment S4, and the second imaginary line AL2, but not limited thereto. In Figure 1 and Figure 2 , there may be a second distance DS2 between the second compensation metal line segment 128b and the second break point portion CP2, and the second distance DS2 may be greater than or equal to 3 micrometers and less than or equal to 50 micrometers, or may be greater than or equal to 3 micrometers and less than or equal to 15 micrometers, but not limited thereto.
[0072] In some embodiments (such as Figure 1 and Figure 2 ), the angle between the line connecting the midpoints of the second compensation metal line segment 128b and the second break point portion CP2 and the second direction D2 may be greater than or equal to 80 degrees and less than or equal to 100 degrees, but not limited thereto. According to this design, the offset of the second compensation metal line segment 128b along the second direction D2 with respect to the second break point portion CP2 can be reduced.
[0073] In the present invention, the length of the second compensation metal line segment 128b can be designed according to requirements, and there may be a correlation between the length of the second compensation metal line segment 128b and the length of the second break point portion CP2. In some embodiments, the ratio of the length of the second compensation metal line segment 128b to the length of the second break point portion CP2 may be greater than or equal to 0.7 and less than or equal to 1.3, but not limited thereto. In some embodiments, the length of the second compensation metal line segment 128b may be greater than or equal to 10 micrometers and less than or equal to 60 micrometers, but not limited thereto. In some embodiments, the difference between the length of the second compensation metal line segment 128b and the length of the second break point portion CP2 may be less than or equal to 4 micrometers, but not limited thereto.
[0074] In the present invention, the first compensation metal line segment 128a and the second compensation metal line segment 128b can be designed to be the same or different according to requirements.
[0075] In the present invention, the first metal line segment S1, the second metal line segment S2, the third metal line segment S3, the fourth metal line segment S4, the first compensation metal line segment 128a, and the second compensation metal line segment 128b are all included in the first conductive layer 120. Therefore, compared with the technology of disposing the compensation metal line segment in a different layer, the present invention can reduce the manufacturing cost of the first metal grid 122 having the compensation metal line segment and can reduce the capacitance value between the compensation metal line segment and the metal line segment for sensing (for example, the capacitance caused by the overlap between different conductive layers can be avoided). In addition, in some embodiments (for example, when the first conductive layer 120 is disposed on a flat surface), the top surfaces of the first metal line segment S1, the second metal line segment S2, the first compensation metal line segment 128a, and the second compensation metal line segment 128b are coplanar with each other (as Figure 3 shown), but not limited thereto.
[0076] In the present invention, the electronic device 100 may further include any required elements or structures. In some embodiments (such as Figure 3 ), the conductive layer included in the electronic device 100 may further include a second conductive layer 130, and at least a part of the first conductive layer 120 and at least a part of the second conductive layer 130 are separated from each other. For example, in some embodiments (such as Figure 3 ), the electronic device 100 may further include an insulating layer 140 disposed between the first conductive layer 120 and the second conductive layer 130, and the material of the insulating layer 140 may include, for example, silicon oxide (SiO x ), silicon nitride (SiN y ), silicon oxynitride (SiO x N y ), organic insulating materials, other suitable insulating materials, or combinations thereof, but not limited thereto. For example, in some embodiments (not shown in the figure), the substrate 110 may be disposed between the first conductive layer 120 and the second conductive layer 130 (that is, the first conductive layer 120 and the second conductive layer 130 are respectively disposed on two opposite surfaces of the substrate 110), but not limited thereto.
[0077] In some embodiments, the second conductive layer 130 may include a second metal grid 132, and the design of the second metal grid 132 may be similar to that of the first metal grid 122, so it will not be repeated here. It should be noted that the relative relationship between the first metal grid 122 and the second metal grid 132 can be designed according to requirements. For example, in a top view, the first metal grid 122 and the second metal grid 132 may be offset from each other. In some embodiments, the intersection of the two metal lines 122a and 122b in the first metal grid 122 does not overlap with the intersection of the two metal lines of the second metal grid 132 (for example, the intersection of the two metal lines 122a and 122b in the first metal grid 122 is located at the center of the metal grid unit of the second metal grid 132), but this is not limiting. It should be noted that the arrangement direction of the plurality of grid electrodes in the second metal grid 132 may be different from the direction X (the arrangement direction of the first metal grid 122 and the second grid electrode 126 in the first metal grid 122), and the long direction in the second metal grid 132 may not be parallel to the direction Y (the long direction of the first metal grid 122 and the second grid electrode 126 in the first metal grid 122). For example, the grid electrodes in the second metal grid 132 may be alternately arranged in the direction Y, and the long direction of the grid electrodes may be parallel to the direction X, but this is not limiting.
[0078] Due to the presence of the second metal grid 132, the first metal grid 122 and the second metal grid 132 can perform sensing simultaneously. For example, the first metal grid 122 and the second metal grid 132 can be used as self - capacitance sensors or mutual - capacitance sensors, but this is not limiting.
[0079] The electronic device of the present invention is not limited to the above - mentioned embodiments. Other embodiments will be further disclosed below. However, for the sake of simplifying the description and highlighting the differences between each embodiment and the above - mentioned embodiments, the same reference numerals are used to label the same components in the following text, and the repeated parts will not be described again.
[0080] Please refer to Figure 4 , Figure 4 which shows a top - view schematic diagram of the first conductive layer of the electronic device according to the second embodiment of the present invention. As Figure 4 shown, the difference between this embodiment and the first embodiment lies in the design of the compensation metal line segments of the electronic device 200. In Figure 4In this case, the first compensation metal line segment 128a may not overlap with the first break point portion CP1 at all, and the first compensation metal line segment 128a may not be parallel to the first direction D1 and the second direction D2. Optionally, the second compensation metal line segment 128b may not overlap with the second break point portion CP2 at all, and the second compensation metal line segment 128b may not be parallel to the first direction D1 and the second direction D2. It should be noted that the angle between the first compensation metal line segment 128a and the first direction D1 may be the same as or different from the angle between the second compensation metal line segment 128b and the second direction D2.
[0081] In some embodiments (not shown in the figures), the arrangement of the second compensation metal line segment 128b may be different from that of the first compensation metal line segment 128a. For example, the first compensation metal line segment 128a may not be parallel to the first direction D1 and the second direction D2, while the second compensation metal line segment 128b may be parallel to the second direction D2, but this is not limiting.
[0082] Please refer to Figure 5 , Figure 5 which shows a top view schematic diagram of the first conductive layer of the electronic device according to the third embodiment of the present invention. As Figure 5 shown, the difference between this embodiment and the first embodiment lies in the design of the compensation metal line segments of the electronic device 300. In Figure 5 , the first compensation metal line segment 128a and the first imaginary line AL1 may have at least one intersection point (i.e., the first compensation metal line segment 128a partially overlaps with the first break point portion CP1). Since the first compensation metal line segment 128a does not completely overlap with the first break point portion CP1, the first compensation metal line segment 128a is not parallel to the first direction D1. For example, in some embodiments (such as Figure 5 ), the first compensation metal line segment 128a may not be parallel to the first direction D1 and the second direction D2, but this is not limiting. For example, in some embodiments (not shown in the figures), the first compensation metal line segment 128a may be perpendicular to the first direction D1 or parallel to the second direction D2, but this is not limiting.
[0083] The position of the intersection point of the first compensation metal line segment 128a and the first imaginary line AL1 can be designed according to requirements. In some embodiments (such as Figure 5 ), the intersection point of the first compensation metal line segment 128a and the first imaginary line AL1 may be located at the midpoint between the first end point E1 and the second end point E2, but this is not limiting. In some embodiments (such as Figure 5 ), the intersection point of the first compensation metal line segment 128a and the first imaginary line AL1 may be located at the midpoint of the first compensation metal line segment 128a, but this is not limiting.
[0084] In Figure 5In [the figure], the second compensation metal line segment 128b and the second imaginary line AL2 may have at least one intersection point (i.e., the second compensation metal line segment 128b partially overlaps the second break point portion CP2), and the second compensation metal line segment 128b is not parallel to the second direction D2. For example, in some embodiments (such as Figure 5 ), the second compensation metal line segment 128b may not be parallel to the first direction D1 and the second direction D2, but is not limited thereto. For example, in some embodiments (not shown in the figure), the second compensation metal line segment 128b may be perpendicular to the second direction D2 or parallel to the first direction D1, but is not limited thereto. It should be noted that the angle between the first compensation metal line segment 128a and the first direction D1 may be the same as or different from the angle between the second compensation metal line segment 128b and the second direction D2.
[0085] The position of the intersection point of the second compensation metal line segment 128b and the second imaginary line AL2 can be designed according to requirements. In some embodiments (such as Figure 5 ), the intersection point of the second compensation metal line segment 128b and the second imaginary line AL2 may be located at the midpoint of the third end point E3 and the fourth end point E4, but is not limited thereto. In some embodiments (such as Figure 5 ), the intersection point of the second compensation metal line segment 128b and the second imaginary line AL2 may be located at the midpoint of the second compensation metal line segment 128b, but is not limited thereto.
[0086] In some embodiments (not shown in the figure), the setting of the second compensation metal line segment 128b may be different from the setting of the first compensation metal line segment 128a. For example, the first compensation metal line segment 128a and the first imaginary line AL1 may have at least one intersection point, and the second compensation metal line segment 128b may not overlap the second break point portion CP2 at all, but is not limited thereto.
[0087] Please refer to Figure 6 , Figure 6 which shows a top view schematic diagram of the first conductive layer of the electronic device according to the fourth embodiment of the present invention. As Figure 6 shown, the difference between this embodiment and the first embodiment lies in the design of the break point portion of the metal grid of the electronic device 400. In Figure 6 , at least one break point portion of the first metal grid 122 may be provided in the first grid electrode 124 to adjust the electrical property of the first grid electrode 124. For example, the present invention can adjust the resistance value of the first grid electrode 124 by the number of break point portions, but is not limited thereto.
[0088] Specifically, the metal grid unit MU2 may include a first metal line segment S1 and a second metal line segment S2. The first metal line segment S1 and the second metal line segment S2 are separated from each other and both extend along a first direction D1. A first break point portion CP1 exists between a first end point E1 of the first metal line segment S1 and a second end point E2 of the second metal line segment S2. The first metal line segment S1 and the second metal line segment S2 are both included in the first grid electrode 124, such that the first metal line segment S1 is electrically connected to the second metal line segment S2. In some embodiments (such as Figure 6 shown), the first metal line segment S1 and the second metal line segment S2 may be electrically connected to each other through other parts of the metal grid unit MU2 including the first metal line segment S1 and the second metal line segment S2, but not limited thereto. In some embodiments (not shown in the figure), the first metal line segment S1 and the second metal line segment S2 may be electrically connected to each other through other metal grid units MU, but not limited thereto.
[0089] The design of the first compensation metal line segment 128a may be one of the above embodiments. For example, in Figure 6 , the first compensation metal line segment 128a may not overlap with the first break point portion CP1 at all, and the first compensation metal line segment 128a may be parallel to the first direction D1, but not limited thereto.
[0090] Optionally, in some embodiments (not shown in the figure), the metal grid unit MU2 may further include a third metal line segment S3 and a fourth metal line segment S4. The third metal line segment S3 and the fourth metal line segment S4 are separated from each other and both extend along a second direction D2. A second break point portion CP2 exists between a third end point E3 of the third metal line segment S3 and a fourth end point E4 of the fourth metal line segment S4. The third metal line segment S3 and the fourth metal line segment S4 are both included in the first grid electrode 124, such that the third metal line segment S3 is electrically connected to the fourth metal line segment S4. In some embodiments (not shown in the figure), when both the first break point portion CP1 and the second break point portion CP2 exist in the same metal grid unit MU2, the first metal line segment S1, the second metal line segment S2, the third metal line segment S3, and the fourth metal line segment S4 may be electrically connected to each other through other metal grid units MU2, but not limited thereto. It should be noted that the design of the second compensation metal line segment 128b may be one of the above embodiments.
[0091] In summary, since the compensation metal line segment is adjacent to and does not completely overlap with the break point portion, the adverse visual effect caused by the break point portion can be compensated or reduced. And since the compensation metal line segment and the metal line segment beside the break point portion belong to the same conductive layer, the manufacturing cost of the metal grid with the compensation metal line segment can be reduced.
[0092] The above are only the preferred embodiments of the present invention, and all equivalent changes and modifications made according to the scope of the claims of the present invention shall fall within the scope of the present invention.
