In addition, the light-emitting unit104a,light-emitting unit104b,and light-emitting unit104cmay serve as subpixels. In some embodiments, the light-emitting unit104a,light-emitting unit104b,and light-emitting unit104cmay 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 unit104) 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 substrate102may 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 substrate102may 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 device10may include an antenna106disposed between the light-emitting units104. The antenna106may receive and/or transmit the electromagnetic wave. The antenna106may be electrically connected to a controller108(e.g., as shown inFIG. 5) in accordance with some embodiments. More specifically, the antenna106may receive the electromagnetic wave from the environment and generate induced current to the controller in the electronic device10. The controller may also control the current flowing to the antenna106to transmit the electromagnetic wave.

In some embodiments, the material of the antenna106may 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 antenna106may 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 addition, the antenna106may be a single layered structure, or a multiple layered structure.

In some embodiments, at least a portion of the antenna106may have a first width W1. In some embodiments, a distance between two adjacent light-emitting units104that are located at opposite sides of the antenna106may be a first distance D1. In one example where the light-emitting units104are 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 units104. In other examples where the light-emitting units104are packaged light-emitting diodes, the first distance D1is the distance between the packages of the light-emitting units104. 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 antenna106may 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 antenna106may reflect light and thus the visual effect of the electronic device10may be affected.

Specifically, the first width W1may be the maximum width of the antenna106on the plane that is substantially perpendicular to the normal direction of the first substrate102, e.g., the X-Y plane, as shown inFIG. 1. It should be understood that the width of the antenna106described herein may refer to the width of the antenna106that is disposed between two adjacent light-emitting units104in a display region of the electronic device10(e.g., as shown in region B ofFIG. 8). Moreover, the first distance D1may refer to the minimum distance between two adjacent light-emitting units104that are located at opposite sides of the antenna106. For example, as shown inFIG. 1, the first distance D1may refer to the minimum distance between two light-emitting units104a,two light-emitting units104b,or two light-emitting units104cthat are located at opposite sides of the antenna106.

More specifically, in the embodiments where the antenna106includes several line segment portions, the width of the antenna106may refer to the width that is substantially perpendicular to the extending direction of the line segment portion. For example, as shown inFIG. 1, the antenna106may include a first portion106athat 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 portion106aof the antenna106may refer to the width that is substantially perpendicular to the extending direction.

On the other hand, in the embodiments where the antenna106includes curved portions, the width of the antenna106may refer to the width that is substantially perpendicular to a tangent T of the curved portion. For example, refer toFIGS. 2A and 2B, which are top-view diagrams of the antenna106in accordance with some embodiments of the present disclosure. The antenna106may include one or more curved portions106r.The width W of the curved portion106rof the antenna106may refer to the width that is substantially perpendicular to the tangent T of the curved portion106r.

In addition, referring toFIG. 1again, the antenna106may include the first portion106aextending along a first direction E1and a second portion106bextending along a second direction E2different from the first direction E1in accordance with some embodiments. In other embodiments, the antenna106may include other portion(s) extending along other direction(s), but it is not limited thereto. The first width W1of the first portion106amay be the same as or different from a second width W2of the second portion106b.In some embodiments, the first width W1of the first portion106amay be greater than the second width W2of the second portion106b.In some embodiments, the first distance D1may refer to a subpixel distance between two adjacent subpixels (light-emitting units104). As shown inFIG. 1, the first distance D1corresponding to the first portion106amay be greater than a second distance D2corresponding to the second portion106b.More specifically, the first distance D1between two adjacent subpixels that are located at opposite sides of the first portion106amay be greater than the second distance D2between two adjacent subpixels that are located at opposite sides of the second portion106b.The antenna106may include a turning portion106tdisposed between two portions (e.g., the first portion106aand the second portion106b), but it is not limited thereto. In some examples, the turning portion may connect the first portion106aand the second portion106b.

In some embodiments, a gap distance may refer to the minimum distance between the antenna106and the light-emitting units104. In addition, the gap distance may be the distance between the antenna106and the bare die of the light-emitting unit, or the distance between the antenna106and the package of the light-emitting unit104, depending on the type of the light-emitting unit104, but it is not limited thereto. As shown inFIG. 1, in some embodiments, the first gap distance G1corresponding to the first portion106amay be greater than a second gap distance G2that corresponds to the second portion106b.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 antenna106may be too close to some of the light-emitting units104and may affect the performance of the electronic device10. In some embodiments, the antenna106may overlap a midpoint M of the first distance D1between two adjacent light-emitting units104, and thus the antenna106may not be too close to or too far from the light-emitting units104. The term “overlap” may refer to partially overlap or entirely overlap in the normal direction of the first substrate102in the present disclosure.

Moreover, in some embodiments, the ratio of the first width W1of the antenna106to a width WLof one of the light-emitting units104may 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 WLis too small (e.g., less than about 0.4), the performance of the antenna106may be poor due to high resistance. On the other hand, if the ratio of the first width W1to the width WLis too large (e.g., greater than about100), the antenna106may reflect light and the display quality of the electronic device10may be affected.

In one example where the light-emitting unit104is a bare-die light-emitting diode, the width WLof the light-emitting unit104may refer to the maximum width of the bare die. In other examples where the light-emitting unit104is a packaged light-emitting diode, the width WLof the light-emitting unit104may 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 unit104. In embodiments where the profile of the light-emitting unit104has obvious corners, the width WLof the light-emitting unit104may refer to the maximum distance between two corners. For example, refer toFIGS. 2C and 2D, which are top-view diagrams of the light-emitting unit104in accordance with some embodiments of the present disclosure. The width WLof the light-emitting unit104may refer to the maximum distance between two corners C of the profile of the light-emitting unit104. On the other hand, in embodiments where the profile of the light-emitting unit104does not have obvious corners, the width WLof the light-emitting unit104may be obtained by actual measurement of the maximum distance between two points of the profile, as shown inFIG. 2E.

Referring toFIG. 1, in some embodiments, the antenna106may further include several first portions106aextending along the first direction E1and several second portions106bextending along the second direction E2. In some embodiments, the first portions106aand the second portions106bmay be connected to form a continuous structure. In some embodiments, the antenna106may include several spiral or loop structures. As shown inFIG. 1, the antenna106may 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.

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 inFIG. 3, the antenna106may be disposed between two adjacent pixels P in accordance with some embodiments. Moreover, the antenna106may not be disposed between two adjacent subpixels (e.g., between the light-emitting units104aand104b,or between the light-emitting units104band104c) in accordance with some embodiments. In other words, the pixel P may not be interrupted by layout of the antenna106in accordance with some embodiments. In particular, since one pixel P may serve as a unit for display, the antenna106disposed between the pixels P rather than between the subpixels may have better display quality.

In some embodiments, the antenna106may include turning portions106t.The turning portion106tmay be located at the position where the extending direction of the antenna106is changed. For example, as shown inFIG. 3, the turning portion106tmay be located at the position where the first portion106ais connected to the second position106b,i.e. the position where the extending direction of the antenna106is changed from the first direction E1to the second direction E2. In some embodiments, the turning portion106tmay also be disposed between the pixels P, rather than between the subpixels (e.g., between the light-emitting units104aand104b,or between the light-emitting units104band104c). In addition, in some embodiments, one pixel P may include N subpixels (light-emitting units104), i.e. the number of subpixels is N. In some embodiments, the first portion106amay 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 inFIG. 3, the pixel P may include three subpixels, and the first portion106amay pass through or pass by 3n subpixels, e.g., 3, 6, 9, 12, 15 subpixels in accordance with some embodiments.

In some embodiments, the combined first portion106a′ may extend in the first direction E1, and the combined second portion106b′ may extend in the second direction E2. In some embodiments, some of the second portions106bmay be disposed between subpixels. In some embodiments, the antenna106that includes part of the combined first portion106a′ or part of the combined second portion106b′ may be disposed between subpixels. The combined first portion106a′ and the combined second portion106b′ may increase the area of the antenna106in the electronic device30, and the resistance of the antenna106may be reduced.

In some embodiments, the combined first portion106a′ and the combined second portion106b′ may include openings107disposed therein. The light-emitting units104may be disposed in the openings107. In some embodiments, the opening107may be surrounded by the first portions106aand the second portions106b.Although one opening107may encompass one light-emitting unit104in the embodiment shown inFIG. 4, one opening107may encompass more than one light-emitting units104in accordance with some other embodiments. In other words, the numbers of the first portions106aand the second portions106bin the combined first portion106a′ or the combined second portion106b′ may be adjusted depending on need in various embodiments.

In some embodiments, the combined first portion106a′ and the combined second portion106b′ may be formed by using one or more deposition processes, photolithography processes and etching process.

In addition, as described above, the antenna106may be electrically connected to a controller108to receive and/or transmit the electromagnetic wave. In some embodiments, the controller108may include a driving element, a signal processer or a combination thereof. For example, the antenna106may 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 antenna106. 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 device10. In some embodiments, the IC may control the antenna106and signals lines (e.g., data lines and scan lines) at the same time.

Specifically, in some embodiments, the electronic device60may include a circuit layer (as shown inFIGS. 10A-10D) disposed on the first substrate102or 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 antenna106. With such a configuration, the issues of signal interference, capacitive coupling and so on may be reduced in the electronic device60. In some embodiments, the metal lines may include signal lines for controlling the light-emitting units104.

In some embodiments, the recessed portion R of the antenna106may be formed by using photolithography processes, etching process, or a combination thereof.

Moreover, in some embodiment, the interval arrangement of the light-emitting units104may be different in the different directions. For example, as shown inFIG. 7, the interval between the light-emitting units104in the Y direction is greater than the interval between the light-emitting units104in the X direction. In such a configuration, the antenna106may be designed to have greater dimensions in the Y direction.

As shown inFIG. 10A, the electronic device80may further include a wavelength conversion layer204disposed on the light-emitting unit104in accordance with some embodiments. In some embodiments, the wavelength conversion layer204may disposed within or on the second substrate202. In other embodiments, the wavelength conversion layer204may be disposed between the light-emitting unit104and the second substrate202, and/or the second substrate202may be disposed between the wavelength conversion layer204and the light-emitting unit104, but it is not limited thereto. In some embodiments, the light-emitting unit104may emit white light, blue light, green light, red light, or UV light. The wavelength conversion layer204may convert the light emitted from the light-emitting unit104into the colors that are needed. For example, the wavelength conversion layer204may convert the light emitted from the light-emitting unit104into red light, green light or blue light in accordance with embodiments. In some examples, the wavelength conversion layer204may convert a part of the light from the light-emitting unit104, while the other part of the light may not be converted, but is it not limited thereto. In addition, in some embodiments, a top surface106S of the antenna106may be lower than a top surface104S of the light-emitting unit104.

In some embodiments, the top surface106S of the antenna106may be lower than a top surface204S of the wavelength conversion layer204. In addition, in some embodiments, a thickness T1of the antenna106may be less than a thickness T2of the light-emitting unit104. In other embodiments, the thickness T1of the antenna106may be less than a sum of a thickness T2of the light-emitting unit104and a thickness of the wavelength conversion layer204. In such a configuration, the antenna106may interfere less with the emitting of light-emitting unit104. In some embodiments, a thickness T3of the circuit layer110may be less than the thickness T1of the antenna106. In accordance with some embodiments, the thickness T1, T2and T3may refer to the largest thickness in the normal direction of the first substrate102or the second substrate202.

In some embodiments, the material of the wavelength conversion layer204may include, but is not limited to, quantum dot (QD) materials, fluorescence materials, phosphor materials, or a combination thereof.

It should be understood that although the detailed structure of the light-emitting unit104is not illustrated in the figures, the light-emitting unit104may have any suitable structure depending on need. For example, in embodiments where the light-emitting unit104may be LED, the light-emitting unit104may include a first semiconductor layer having a p-type conductivity type, a second semiconductor layer having an n-type conductivity type, a quantum well layer disposed between the first semiconductor layer and the second semiconductor layer, and the p-electrode (e.g., the first electrode104p) and an n-electrode (e.g., the second electrode104n) respectively electrically connected to the first semiconductor layer and the second semiconductor layer. Moreover, the material of first semiconductor layer may include p-type gallium nitride (p-GaN), and the material of the second semiconductor layer may include n-type gallium nitride (n-GaN). The quantum well layer may include a single quantum well (SQW) or a multiple quantum well (MQW), and the material of the quantum well layer may include, but is not limited to, indium gallium nitride, gallium nitride or a combination thereof.

Next, referring toFIG. 10B, the embodiments shown inFIG. 10Bis similar to the embodiments shown inFIG. 10A. The difference between them is that the antenna106may be disposed on the second substrate202in the embodiments shown inFIG. 10B. Similarly, in this embodiment, the antenna106and the light-emitting units104may not overlap in the normal direction of the first substrate102.

Next, referring toFIG. 10C, the embodiments shown inFIG. 10Cis similar to the embodiments shown inFIG. 10A. The difference between them is that the light-emitting unit104may be disposed on the second substrate202in the embodiments shown inFIG. 10C. In addition, the first electrode104pand the second electrode104nof the light-emitting units104may penetrate through the second substrate202and be electrically connected to the circuit layer110. Next, referring toFIG. 10D, the embodiments shown inFIG. 10Dis similar to the embodiments shown inFIG. 10C. The difference between them is electronic device80may not include the wavelength conversion layer204in the embodiments shown inFIG. 10D. In this embodiment, the light-emitting units104may emit red light, green light and/or blue light. It is noted that inFIGS. 10A-10D, the second substrate202may be disposed on the light-emitting units104or disposed adjacent to the light-emitting unit104sin accordance with some embodiments of the present disclosure. In some examples, at least one intermediate layer may be disposed between the second substrate202and the light-emitting units104, but it is not limited thereto.

Next, refer toFIG. 11, which is a top-view diagram of an electronic device90in accordance with some other embodiments of the present disclosure. As shown inFIG. 11, the electronic device90may include different types of light-emitting units, i.e. hybrid-type light-emitting units. Specifically, in some embodiments, the electronic device90may include the light-emitting units104and light-emitting units304. In some embodiments, the light-emitting units104may include LED, quantum dot LED (QDLED), mini LED, micro LED, or a combination thereof. In some embodiments, the light-emitting units304may include OLED, QLED or a combination thereof. In other embodiments, the light-emitting units304may 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 units304serve as the backlight module of a liquid-crystal display, the electronic device90may further include a display panel disposed on the backlight module. As shown inFIG. 11, the light-emitting units304(e.g., the light-emitting unit304a,light-emitting unit304b,and light-emitting unit304c) may also serve as subpixels for emitting red light, green light and blue light respectively in accordance with some embodiments.

In some embodiments, the light-emitting unit104may have a first subpixel area A1and the light-emitting unit304may 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 units304may have greater subpixel areas, there may be less space between the light-emitting units304to dispose the antenna106. Therefore, the antenna106may be disposed between the light-emitting units104and the light-emitting units304in accordance with some embodiments. In other words, the antenna106may be disposed between the light-emitting units having different subpixel areas. Moreover, in some embodiments, the antenna106may be disposed near the boundary (e.g., indicated as region G) between the light-emitting units104and the light-emitting units304.

To summarize the above, in accordance with some embodiments of the present disclosure, the width of the antenna and the distance between subpixels may be controlled in specific ranges so that the dimension of the antenna may be increased and the resistance of the antenna may be reduced. 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.
