FIG. 1 is a top-view diagram of an electronic device 10 in accordance with some embodiments of the present disclosure. It should be understood that some of the components of the electronic device 10 such as the driving element, the signal processor, and the circuit are omitted in FIG. 1 for clarity. In addition, it should be understood that additional features may be added to the electronic device in accordance with some embodiments of the present disclosure.
Referring to FIG. 1, the electronic device 10 may include a plurality of light-emitting units 104 disposed on a first substrate 102. In some embodiments, the light-emitting units 104 may include a light-emitting diode, other suitable light-emitting units, or a combination thereof. In addition, the electronic device 10 may include a plurality of pixels P and at least one of the pixels P may include several light-emitting units 104. In some embodiments, at least one of the pixels P may include three, four, or other suitable amounts of the light-emitting units. For example, as shown in FIG. 1, the pixel P may include three light-emitting units 104, which are denoted as light-emitting unit 104 a, light-emitting unit 104 b, and light-emitting unit 104 c for clarity, in accordance with some embodiments. In addition, the light-emitting unit 104 a, light-emitting unit 104 b, and light-emitting unit 104 c may serve as subpixels. In some embodiments, the light-emitting unit 104 a, light-emitting unit 104 b, and light-emitting unit 104 c may emit red light, green light and blue light respectively, but it is not limited thereto. In some other embodiments, at least one of the pixels P may include, but is not limited to, four subpixels (light-emitting unit 104) for emitting red light, green light, blue light and yellow light, or for emitting red light, green light, blue light and white light.
In some embodiments, the material of the first substrate 102 may include, but is not limited to, glass, quartz, sapphire, polycarbonate (PC), polyimide (PI), polyethylene terephthalate (PET), rubbers, glass fibers, other polymer materials, any other suitable substrate material, or a combination thereof. In some embodiments, the first substrate 102 may include a metal-glass fiber composite substrate, a metal-ceramic composite substrate, a printed circuit board, or any other suitable substrate, but it is not limited thereto.
In addition, the electronic device 10 may include an antenna 106 disposed between the light-emitting units 104. The antenna 106 may receive and/or transmit the electromagnetic wave. The antenna 106 may be electrically connected to a controller 108 (e.g., as shown in FIG. 5) in accordance with some embodiments. More specifically, the antenna 106 may receive the electromagnetic wave from the environment and generate induced current to the controller in the electronic device 10. The controller may also control the current flowing to the antenna 106 to transmit the electromagnetic wave.
In some embodiments, the material of the antenna 106 may include conductive materials. In some embodiments, the conductive material may include, but is not limited to, copper, aluminum, molybdenum, tungsten, gold, chromium, nickel, platinum, titanium, silver, copper alloys, aluminum alloys, molybdenum alloys, tungsten alloys, gold alloys, chromium alloys, nickel alloys, platinum alloys, titanium alloys, silver alloys, any other suitable conductive materials (e.g., carbon nano-tubes), or a combination thereof In some embodiments, the materials of the antenna 106 may include transparent conductive materials. For example, the transparent conductive material may include, but is not limited to, indium tin oxide (ITO), tin oxide (SnO), indium zinc oxide (IZO), indium gallium zinc oxide (IGZO), indium tin zinc oxide (ITZO), any other suitable transparent conductive materials, or a combination thereof. In some embodiments, the materials of the antenna 106 may include conductive polymers. For example, the conductive polymer may include, but is not limited to, poly (3,4-ethylenedioxythiophene), polystyrene sulfonate (PEDOT:PSS), polythiophenes (PT), polypyrrole (PPY), polyphenylene sulfide (PPS), or a combination thereof. In addition, the antenna 106 may be a single layered structure, or a multiple layered structure.
In some embodiments, at least a portion of the antenna 106 may have a first width W₁. In some embodiments, a distance between two adjacent light-emitting units 104 that are located at opposite sides of the antenna 106 may be a first distance D₁. In one example where the light-emitting units 104 are bare-die light-emitting diodes, the first distance D₁is the distance between the bare dies (i.e. without package structures) of the two adjacent light-emitting units 104. In other examples where the light-emitting units 104 are packaged light-emitting diodes, the first distance D₁is the distance between the packages of the light-emitting units 104. In some embodiments, the ratio of the first width W₁to the first distance D₁may be ranged from about 0.1 to about 0.8, or from about 0.2 to about 0.6, such as 0.3, 0.4, or 0.5. In particular, if the ratio of the first width W₁to the first distance D₁is too small (e.g., less than about 0.1), the performance of the antenna 106 may be poor due to high resistance. On the other hand, if the ratio of the first width W₁to the first distance D₁is too large (e.g., greater than about 0.8), the antenna 106 may reflect light and thus the visual effect of the electronic device 10 may be affected.
Specifically, the first width W₁may be the maximum width of the antenna 106 on the plane that is substantially perpendicular to the normal direction of the first substrate 102, e.g., the X-Y plane, as shown in FIG. 1. It should be understood that the width of the antenna 106 described herein may refer to the width of the antenna 106 that is disposed between two adjacent light-emitting units 104 in a display region of the electronic device 10 (e.g., as shown in region B of FIG. 8). Moreover, the first distance D₁may refer to the minimum distance between two adjacent light-emitting units 104 that are located at opposite sides of the antenna 106. For example, as shown in FIG. 1, the first distance D₁may refer to the minimum distance between two light-emitting units 104 a, two light-emitting units 104 b, or two light-emitting units 104 c that are located at opposite sides of the antenna 106.
More specifically, in the embodiments where the antenna 106 includes several line segment portions, the width of the antenna 106 may refer to the width that is substantially perpendicular to the extending direction of the line segment portion. For example, as shown in FIG. 1, the antenna 106 may include a first portion 106 a that extends in an extending direction substantially the same as or different from the X-axis (e.g., the first direction E₁). The width of the first portion 106 a of the antenna 106 may refer to the width that is substantially perpendicular to the extending direction.
On the other hand, in the embodiments where the antenna 106 includes curved portions, the width of the antenna 106 may refer to the width that is substantially perpendicular to a tangent T of the curved portion. For example, refer to FIGS. 2A and 2B, which are top-view diagrams of the antenna 106 in accordance with some embodiments of the present disclosure. The antenna 106 may include one or more curved portions 106 r. The width W of the curved portion 106 r of the antenna 106 may refer to the width that is substantially perpendicular to the tangent T of the curved portion 106 r.
In addition, referring to FIG. 1 again, the antenna 106 may include the first portion 106 a extending along a first direction E₁and a second portion 106 b extending along a second direction E₂different from the first direction E₁in accordance with some embodiments. In other embodiments, the antenna 106 may include other portion(s) extending along other direction(s), but it is not limited thereto. The first width W₁of the first portion 106 a may be the same as or different from a second width W₂of the second portion 106 b. In some embodiments, the first width W₁of the first portion 106 a may be greater than the second width W₂of the second portion 106 b. In some embodiments, the first distance D₁may refer to a subpixel distance between two adjacent subpixels (light-emitting units 104). As shown in FIG. 1, the first distance D₁corresponding to the first portion 106 a may be greater than a second distance D₂corresponding to the second portion 106 b. More specifically, the first distance D₁between two adjacent subpixels that are located at opposite sides of the first portion 106 a may be greater than the second distance D₂between two adjacent subpixels that are located at opposite sides of the second portion 106 b. The antenna 106 may include a turning portion 106 t disposed between two portions (e.g., the first portion 106 a and the second portion 106 b), but it is not limited thereto. In some examples, the turning portion may connect the first portion 106 a and the second portion 106 b.
In some embodiments, a gap distance may refer to the minimum distance between the antenna 106 and the light-emitting units 104. In addition, the gap distance may be the distance between the antenna 106 and the bare die of the light-emitting unit, or the distance between the antenna 106 and the package of the light-emitting unit 104, depending on the type of the light-emitting unit 104, but it is not limited thereto. As shown in FIG. 1, in some embodiments, the first gap distance G₁corresponding to the first portion 106 a may be greater than a second gap distance G₂that corresponds to the second portion 106 b. Moreover, in some embodiments, the ratio of a first gap distance G₁to the first distance D₁may be ranged from about 0.05 to about 0.75, or from about 0.25 to about 0.75, such as 0.3, 0.35, 0.4, 0.45, 0.5, 055, 0.6, 0.65, or 0.7.
It should be noted that if the ratio of the first gap distance G₁to the first distance D₁is too small (e.g., less than about 0.05) or too large (e.g., greater than about 0.75), the antenna 106 may be too close to some of the light-emitting units 104 and may affect the performance of the electronic device 10. In some embodiments, the antenna 106 may overlap a midpoint M of the first distance D1 between two adjacent light-emitting units 104, and thus the antenna 106 may not be too close to or too far from the light-emitting units 104. The term “overlap” may refer to partially overlap or entirely overlap in the normal direction of the first substrate 102 in the present disclosure.
Moreover, in some embodiments, the ratio of the first width W₁of the antenna 106 to a width W_Lof one of the light-emitting units 104 may be ranged from about 0.4 to about 100, or from about 0.6 to about 75, such as 0.6, 5, 20, or 50. In particular, if the ratio of the first width W₁to the width W_Lis too small (e.g., less than about 0.4), the performance of the antenna 106 may be poor due to high resistance. On the other hand, if the ratio of the first width W₁to the width W_Lis too large (e.g., greater than about 100), the antenna 106 may reflect light and the display quality of the electronic device 10 may be affected.
In one example where the light-emitting unit 104 is a bare-die light-emitting diode, the width W_Lof the light-emitting unit 104 may refer to the maximum width of the bare die. In other examples where the light-emitting unit 104 is a packaged light-emitting diode, the width W_Lof the light-emitting unit 104 may refer to the maximum width of the package. In addition, the maximum width may be the farthest distance between two points on the boundary or profile of the bare die of the light-emitting unit 104. In embodiments where the profile of the light-emitting unit 104 has obvious corners, the width W_Lof the light-emitting unit 104 may refer to the maximum distance between two corners. For example, refer to FIGS. 2C and 2D, which are top-view diagrams of the light-emitting unit 104 in accordance with some embodiments of the present disclosure. The width W_Lof the light-emitting unit 104 may refer to the maximum distance between two corners C of the profile of the light-emitting unit 104. On the other hand, in embodiments where the profile of the light-emitting unit 104 does not have obvious corners, the width W_Lof the light-emitting unit 104 may be obtained by actual measurement of the maximum distance between two points of the profile, as shown in FIG. 2E.
Referring to FIG. 1, in some embodiments, the antenna 106 may further include several first portions 106 a extending along the first direction E₁and several second portions 106 b extending along the second direction E₂. In some embodiments, the first portions 106 a and the second portions 106 b may be connected to form a continuous structure. In some embodiments, the antenna 106 may include several spiral or loop structures. As shown in FIG. 1, the antenna 106 may have a helical shape or a spiral shape in accordance with some embodiments. In addition, the helical or spiral shape may be left-handed or right-handed.
Next, refer to FIG. 3, which is a top-view diagram of an electronic device 20 in accordance with some other embodiments of the present disclosure. In should be understood that the same or similar components or elements in the context of the descriptions provided above and below are represented by the same or similar reference numerals. The materials, manufacturing methods and functions of these components or elements are the same as or similar to those described above, and thus will not be repeated herein. As shown in FIG. 3, the antenna 106 may be disposed between two adjacent pixels P in accordance with some embodiments. Moreover, the antenna 106 may not be disposed between two adjacent subpixels (e.g., between the light-emitting units 104 a and 104 b, or between the light-emitting units 104 b and 104 c) in accordance with some embodiments. In other words, the pixel P may not be interrupted by layout of the antenna 106 in accordance with some embodiments. In particular, since one pixel P may serve as a unit for display, the antenna 106 disposed between the pixels P rather than between the subpixels may have better display quality.
In some embodiments, the antenna 106 may include turning portions 106 t. The turning portion 106 t may be located at the position where the extending direction of the antenna 106 is changed. For example, as shown in FIG. 3, the turning portion 106 t may be located at the position where the first portion 106 a is connected to the second position 106 b, i.e. the position where the extending direction of the antenna 106 is changed from the first direction E₁to the second direction E₂. In some embodiments, the turning portion 106 t may also be disposed between the pixels P, rather than between the subpixels (e.g., between the light-emitting units 104 a and 104 b, or between the light-emitting units 104 b and 104 c). In addition, in some embodiments, one pixel P may include N subpixels (light-emitting units 104), i.e. the number of subpixels is N. In some embodiments, the first portion 106 a may pass through or pass by N x n subpixels (i.e. the amount of subpixels is N times n), wherein n refers to any positive integer. For example, as shown in FIG. 3, the pixel P may include three subpixels, and the first portion 106 a may pass through or pass by 3n subpixels, e.g., 3, 6, 9, 12, 15 subpixels in accordance with some embodiments.
Next, refer to FIG. 4, which is a top-view diagram of an electronic device 30 in accordance with some other embodiments of the present disclosure. As shown in FIG. 4, in some embodiments, the electronic device 30 may include a plurality of first portions 106 a and a plurality of second portions 106 b that are connected to enclose some of the light-emitting units 104. More specifically, several first portions 106 a and several second portions 106 b may be connected together to form a combined first portion 106 a′ and a combined second portion 106 b′. In some embodiments, the combined first portion 106 a′ may extend in the first direction E₁, and the combined second portion 106 b′ may extend in the second direction E₂. In some embodiments, some of the second portions 106 b may be disposed between subpixels. In some embodiments, the antenna 106 that includes part of the combined first portion 106 a′ or part of the combined second portion 106 b′ may be disposed between subpixels. The combined first portion 106 a′ and the combined second portion 106 b′ may increase the area of the antenna 106 in the electronic device 30, and the resistance of the antenna 106 may be reduced.
In some embodiments, the combined first portion 106 a′ and the combined second portion 106 b′ may include openings 107 disposed therein. The light-emitting units 104 may be disposed in the openings 107. In some embodiments, the opening 107 may be surrounded by the first portions 106 a and the second portions 106 b. Although one opening 107 may encompass one light-emitting unit 104 in the embodiment shown in FIG. 4, one opening 107 may encompass more than one light-emitting units 104 in accordance with some other embodiments. In other words, the numbers of the first portions 106 a and the second portions 106 b in the combined first portion 106 a′ or the combined second portion 106 b′ may be adjusted depending on need in various embodiments.
In some embodiments, the combined first portion 106 a′ and the combined second portion 106 b′ may be formed by using one or more deposition processes, photolithography processes and etching process. In some embodiments, the deposition process may include a chemical vapor deposition process, a physical vapor deposition process, an electroplating process, an electroless plating process, another suitable process, or a combination thereof. For example, the chemical vapor deposition process may include a low-pressure chemical vapor deposition (LPCVD) process, a low-temperature chemical vapor deposition (LTCVD) process, a rapid thermal chemical vapor deposition (RTCVD) process, a plasma enhanced chemical vapor deposition (PECVD) process, an atomic layer deposition (ALD) process, and so on. For example, the physical vapor deposition process may include a sputtering process, an evaporation process, pulsed laser deposition, and so on. In addition, in some embodiments, the photolithography process may include photoresist coating (e.g., spin coating), soft baking, hard baking, mask aligning, exposure, post-exposure baking, developing the photoresist, rinsing, drying, and other suitable processes. In some embodiments, the etching process may include a dry etching process, a wet etching process, or another suitable etching process.
Next, refer to FIG. 5, which is a top-view diagram of an electronic device 40 in accordance with some other embodiments of the present disclosure. As shown in FIG. 5, the antenna 106 may have a loop shape. The antenna 106 may include several independent loop structures 106 p in accordance with some embodiments. The number of the loop structures 106 p may be any positive integer. In some embodiments, the loop structures 106 p may be coaxial. The loop structure 106 p may also include the first portions 106 a extending along the first direction E₁and the second portions 106 b extending along the second direction E₂.
In addition, as described above, the antenna 106 may be electrically connected to a controller 108 to receive and/or transmit the electromagnetic wave. In some embodiments, the controller 108 may include a driving element, a signal processer or a combination thereof. For example, the antenna 106 may receive the electromagnetic wave from the environment and generate induced current to the signal processer. The signal processor may then transmit signals to the driving element to control the current flow of the antenna 106. In some embodiments, the driving element may include an active driving element, a passive driving element and/or a combination thereof. For example, the active driving element may include a thin-film transistor (TFT). In some embodiments, the active driving element may be integrated with the circuit of a gate on array (GOP) structure. The passive driving element may be controlled by an IC or a microchip disposed in or outside the electronic device 10. In some embodiments, the IC may control the antenna 106 and signals lines (e.g., data lines and scan lines) at the same time.
It should be understood that although the loop structure 106 p has a square shape in the embodiments shown in FIG. 5, the loop structure may have another suitable shape, such as a circular shape, a diamond shape, and so on depending on need, in accordance with some other embodiments.
Next, refer to FIG. 6, which is a top-view diagram of an electronic device 50 in accordance with some other embodiments of the present disclosure. As shown in FIG. 6, the turning portions 106 t of the antenna 106 may be processed in accordance with some embodiments. In some embodiments, the turning portions 106 t may include a rounded corner, an angled corner, or a combination thereof in accordance with some embodiments. In one example, the rounded corners may have different radius of curvature. In particular, the rounded corner, or angled corner located at the turning portions 106 t may reduce the risk of occurrence of corona discharge, and the performance of the antenna 106 may be improved.
In some embodiments, the rounded corner, or the angled corner of the antenna 106 may be formed by using a photolithography process, an etching process, a grinding process, a polishing process, or a combination thereof.
Next, refer to FIG. 7, which is a top-view diagram of an electronic device 60 in accordance with some other embodiments of the present disclosure. As shown in FIG. 7, the first portion 106 a and the second portion 106 b of the antenna 106 may include recessed portions R. In other words, the width of the first portion 106 a may be inconsistent. The width of the second portion 106 b may be inconsistent. Specifically, in some embodiments, the electronic device 60 may include a circuit layer (as shown in FIGS. 10A-10D) disposed on the first substrate 102 or other metal lines disposed on another layers, the recessed portions R may correspond to the positions of theses circuit layer or metal lines. The recessed portions R may reduce the overlapping area between the circuit layer (or other metal lines) and the antenna 106. With such a configuration, the issues of signal interference, capacitive coupling and so on may be reduced in the electronic device 60. In some embodiments, the metal lines may include signal lines for controlling the light-emitting units 104.
In some embodiments, the recessed portion R of the antenna 106 may be formed by using photolithography processes, etching process, or a combination thereof.
Moreover, in some embodiment, the interval arrangement of the light-emitting units 104 may be different in the different directions. For example, as shown in FIG. 7, the interval between the light-emitting units 104 in the Y direction is greater than the interval between the light-emitting units 104 in the X direction.

Next, refer to FIG. 11, which is a top-view diagram of an electronic device 90 in accordance with some other embodiments of the present disclosure. As shown in FIG. 11, the electronic device 90 may include different types of light-emitting units, i.e. hybrid-type light-emitting units. Specifically, in some embodiments, the electronic device 90 may include the light-emitting units 104 and light-emitting units 304. In some embodiments, the light-emitting units 104 may include LED, quantum dot LED (QDLED), mini LED, micro LED, or a combination thereof. In some embodiments, the light-emitting units 304 may include OLED, QLED or a combination thereof. In other embodiments, the light-emitting units 304 may serve as a backlight module or sub-pixels of a liquid-crystal display (as shown in region G). In addition, in embodiments where the light-emitting units 304 serve as the backlight module of a liquid-crystal display, the electronic device 90 may further include a display panel disposed on the backlight module.

In some embodiments, the light-emitting unit 104 may have a first subpixel area A₁and the light-emitting unit 304 may have a second subpixel area A₂that is greater than the first subpixel area A₁. Since the light intensity of OLED or LCD may be less than that of LED, the area or dimension of subpixels of OLED or LCD may be greater so as to achieve similar light intensity as LED. In some embodiments, since the light-emitting units 304 may have greater subpixel areas, there may be less space between the light-emitting units 304 to dispose the antenna 106. Therefore, the antenna 106 may be disposed between the light-emitting units 104 and the light-emitting units 304 in accordance with some embodiments.

In addition, the antenna may not reflect excess light and therefore the visual effect of the light-emitting units may be unaffected. In accordance with some embodiments of the present disclosure, the arrangement of the layout of the antenna may be designed so that the reflected light generated by the antenna may be reduced and the display quality of the electronic device may be improved.
