The disclosure relates to an electronic device, and in particular to an electronic device which can improve appearance.
The electronic device or the splicing electronic device has been widely applied to different fields such as communication, display, vehicle, or aviation. With the vigorous development of the electronic device, the electronic device is becoming thinner and lighter, so the requirements for reliability or quality of the electronic device are higher.
The disclosure provides an electronic device, which can improve appearance. For example, the electronic device can reduce inconsistency in transmittance of different zones or poor appearance due to the emergence of visual dark lines (for example, concentric circle patterns), but not limited thereto.
According to an embodiment of the disclosure, an electronic device includes a first substrate and a first pattern layer. The first substrate has a first surface and a second surface opposite to each other. The first pattern layer is disposed on the first surface and includes a first grid region and a second grid region. The first grid region includes multiple first grids. The second grid region includes multiple second grids. The first grid region is connected to the second grid region. One of the first grid and the second grid includes a metal grid. Other one of the first grid and the second grid includes a non-metal grid.
The drawings are included to provide a further understanding of the disclosure, and the drawings are incorporated into the specification and constitute a part of the specification. The drawings illustrate embodiments of the disclosure and serve to explain principles of the disclosure together with the description.
The disclosure may be understood with reference to the following detailed description taken in conjunction with the drawings. It should be noted that for the ease of understanding by the reader and the conciseness of the drawings, multiple drawings of the disclosure only depict a part of an electronic device, and specific elements in the drawings may not be drawn according to actual scale. Furthermore, the number and the size of each element in the drawings are illustrative only and are not intended to limit the scope of the disclosure.
In the following specification and claims, terms such as “containing” and “including” are open-ended terms and should thus be interpreted to mean “comprising but not limited to . . . ”.
It should be understood that when an element or a film layer is referred to as being “on” or “connected to” another element or film layer, the element or film layer may be directly on the other element or film layer or directly connected to the other element or film layer, or there may be an element or a film layer inserted between the two (case of indirect connection). In contrast, when an element or a film layer is referred to as being “directly on” or “directly connected to” another element or film layer, there is no element or film layer inserted between the two.
Although terms such as “first”, “second”, and “third” may be used to describe multiple constituent elements, the constituent elements are not limited by the terms. The terms are only used to distinguish a constituent element from other constituent elements in the specification. The claims may not use the same terms, which may be replaced by first, second, third . . . in the order of declaration of the elements in the claims. Therefore, in the following specification, a first constituent element may be a second constituent element in the claims.
In the text, the terms “about”, “approximately”, “substantially”, and “roughly” usually mean within 10%, 5%, 3%, 2%, 1%, or 0.5% of a given value or range. The number given here is an approximate number, that is, in the case where “about”, “approximately”, “substantially”, and “roughly” are not particularly described, the meanings of “about”, “approximately”, “substantially”, and “roughly” may still be implied.
In some embodiments of the disclosure, terms related to bonding and connection such as “connection” and “interconnection”, unless otherwise specified, may mean that two structures are in direct contact or may also mean that the two structures are not in direct contact, wherein there is another structure disposed between the two structures. Also, the terms related to bonding and connection may also include the case where the two structures are both movable or the two structures are both fixed. In addition, the term “coupling” includes any direct and indirect electrical connection means.
In some embodiments of the disclosure, an optical microscope (OM), a scanning electron microscope (SEM), a thin film thickness profilometer (α-step), an ellipsometer, or other suitable manners may be used to measure the area, the width, the thickness, or the height of each element or the distance or the spacing between elements. In detail, according to some embodiments, the scanning electron microscope may be used to obtain a cross-sectional structure image including the element to be measured and measure the area, the width, the thickness, or the height of each element or the distance or the spacing between elements.
An electronic device of the disclosure may include a display apparatus, an antenna device, a sensing device, or a splicing device, but not limited thereto. The electronic device may be a bendable or flexible electronic device. The electronic device may, for example, include a liquid crystal light emitting diode. The light emitting diode may, for example, include an organic light emitting diode (OLED), a mini LED, a micro LED, or a quantum dot (QD) LED (which may, for example, be QLED or QDLED), fluorescence, phosphor, other suitable materials, or any permutation and combination of the materials, but not limited thereto. The antenna device may, for example, be a phased array antenna, but not limited thereto. The splicing device may, for example, be a display splicing device or an antenna splicing device, but not limited thereto. It should be noted that the electronic device may be any permutation and combination of the above, but not limited thereto. The content of the disclosure will be described below with the electronic device, but the disclosure is not limited thereto.
It should be noted that in the following embodiments, without departing from the spirit of the disclosure, features in several different embodiments may be replaced, reorganized, and mixed to complete other embodiments. As long as the features of the various embodiments do not violate the spirit of the invention or are not conflicting, the features may be arbitrarily mixed and matched for use.
Reference will now be made in detail to the exemplary embodiments of the disclosure, and examples of the exemplary embodiments are illustrated in the drawings. Wherever possible, the same reference numerals are used in the drawings and the description to refer to the same or similar parts.

The first pattern layer 120 is disposed on the first surface 111 of the first substrate 110. The first pattern layer 120 includes a first grid region 121 and a second grid region 122. In a normal direction Z of the first substrate 110, the first grid region 121 is connected to the second grid region 122 to cover or overlap with a part of the first surface 111 of the first substrate 110, but not limited thereto. In some embodiments, the connected first grid region 121 and second grid region 122 may also cover or overlap with the entire first surface 111 of the first substrate 110 in the normal direction Z of the first substrate 110.
Specifically, the first grid region 121 has multiple first grids A connected together. The first grid A has multiple grid lines A1 and a through region A2. The grid lines A1 may be connected together to surround the through region A2. The through region A2 may run through the first pattern layer 120 and expose the first surface 111 of the first substrate 110. Additionally, the second grid region 122 has multiple second grids B connected together. The second grid B has multiple grid lines B1 and a through region B2. The grid lines B1 may be connected together to surround the through region B2. The through region B2 may run through the first pattern layer 120 and expose the first surface 111 of the first substrate 110.
In the embodiment, the shapes of the first grid A and the second grid B may, for example, be hollow rectangles formed by crossing four grid lines, but not limited thereto. In some embodiments, the shapes of the first grid and the second grid may also be hollow triangles formed by crossing three grid lines, hollow hexagons formed by crossing six grid lines, or hollow polygons formed by crossing other numbers of grid lines.
In the embodiment, since the line width of the grid line A1 constituting the first grid A may be substantially the same as (or similar to) the line width of the grid line B1 constituting the second grid B, and the shape, the area, and the reflectivity of the first grid A may be substantially the same as (or similar to) the shape, the area, and the reflectivity of the second grid B, the transmittance of the first grid A may 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 may be, for example, less than 5%, but not limited thereto. The transmittance may be obtained by respectively simulating the materials, the shapes, the areas, etc. of the first grid and the second grid or obtained from actual measurements.
In the embodiment, the material of the first grid A in the first grid region 121 may be an opaque and low loss tangent (DO non-metal material, so that the first grid A may be a non-metal grid, but not limited thereto. The material of the second grid B in the second grid region 122 may be an opaque metal material, so that the second grid B may be a metal grid, but not limited thereto. For example, the material of the second grid B may include copper, aluminum, silver, an alloy of the above materials, or other opaque conductive materials. In other embodiments, the material of the first grid A in the first grid region 121 may be an opaque metal material, so that the first grid A may be a metal grid, and the material of the second grid B may be an opaque and low loss tangent non-metal material, so that second grid B may be a non-metal grid. In some embodiments, the material of the second grid B in the second grid region 122 may be an opaque metal grid covered on a low loss tangent non-metal grid. In the embodiment, a method of forming the first pattern layer is to first form a low loss tangent material on the first substrate, then pattern the same to form a grid shape, then form an opaque metal layer on the low loss tangent grid, and pattern the opaque metal layer to form a grid located on a part of the non-metal grid. In addition, compared to a conventional electronic device that has poor appearance such as dark lines (for example, concentric circle patterns) due to a first pattern layer having only one grid region, the electronic device 100 of the embodiment can reduce poor appearance such as dark lines (for example, concentric circle patterns) through the design of the first pattern layer 120 including the first grid region 121 and the second grid region 122 connected to each other, thereby improving the appearance of the electronic device 100.
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 opposite to each other, and the third surface 131 faces the second surface 112. In the embodiment, the material of the second substrate 130 may, for example, be glass or other suitable transparent substrate materials, but not limited thereto.
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 region 141, and the grid region 141 may cover a part of the third surface 131 of the second substrate 130, but not limited thereto. In other words, the grid region 141 of the second pattern layer 140 does not completely cover the third surface 131 of the second substrate 130.
The third pattern layer 150 is disposed on the fourth surface 132 of the second substrate 130. The third pattern layer 150 has a grid region 151, and the grid region 151 may cover a part of the fourth surface 132 of the second substrate 130, but not limited thereto. In other words, the grid region 151 of the third pattern layer 150 does not completely cover the fourth surface 132 of the second substrate 130.
The air gap G is disposed between the second surface 112 of the first substrate 110 and the second pattern layer 140. In other words, the second surface 112 of the first substrate 110 does not contact the second pattern layer 140.
The electronic device 100 of the embodiment may be applied to an antenna device or a transparent antenna device to be used to collect signals, amplify signals, and/or transmit signals.
In the embodiment, the first pattern layer 120 is exemplarily designed as a full-surface grid to improve the inconsistency of transmittance of the full surface or reduce visual dark lines (for example, concentric circle patterns), but not limited thereto. In some embodiments, at least one, at least two, or all of the first pattern layer, the second pattern layer, and the third pattern layer may also be designed as full-surface grids, so as to reduce visual dark lines (for example, concentric circle patterns), thereby improving the appearance.
In the electronic device 100 of the embodiment, 2 substrates and 3 pattern layers are schematically shown, but the disclosure does not limit the number of substrates and pattern layers in the electronic device. In some embodiments, other number of substrates and/or pattern layers may be disposed between the first substrate 110 and the second substrate 130 of the electronic device 100 according to actual requirements or designs.
In the electronic device 100 of the embodiment, although the second grid B of the second grid region 122 is manufactured by using an opaque metal material to provide the purpose of signal transmission, the disclosure is not limited thereto. In some unshown embodiments, the second grid of the second grid region may also use a non-metal material, and a fourth pattern layer used for signal transmission may be additionally manufactured by using an opaque metal material, wherein the fourth pattern layer is disposed on the third pattern layer, and the fourth pattern layer has a third grid region that may overlap with the corresponding second grid region.

In the 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 a through region A2c of the first grid Ac is less than the area of the through region A2 of the first grid A (or the number of the first grids Ac in the first region 1211 is greater than the number of the first grids A in the second region 1218 in the unit area UA of the same size), 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). With such design, a circular pattern of the first region 1211 of the first grid region 121c of the first pattern layer 120c can be presented, and the appearance of the electronic device 100c can be richer and not monotonous.
Although the electronic device 100c of the embodiment exemplarily adjusts the transmittance (or the brightness) of different zones and enriches the pattern of the first pattern layer 120c through adjusting the shapes of the grids of different zones in the first grid region 121c, the disclosure is not limited thereto.

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