[0002] With the development of wireless communication technology, mobile communication products have also developed rapidly. Mobile communication products can realize data transmission functions and achieve resource sharing. Antennas are an essential component in mobile communication products. An antenna is a transducer that converts guided waves propagating on a transmission line into electromagnetic waves propagating in an unbounded medium (usually free space), or vice versa. Antennas can transmit or receive electromagnetic waves and have wide applications in many fields such as communication, radar, navigation, broadcasting, television, remote sensing, and radio astronomy.

The accompanying drawings of the embodiments of this disclosure only relate to the structures involved in the embodiments of this disclosure; other structures can be referred to with reference to general designs.

[0120] The scale of the accompanying drawings in this disclosure can be used as a reference in actual processes, but is not limited thereto. For example, the thickness and spacing of each film layer, and the width and spacing of each signal line, can be adjusted according to actual conditions. The drawings described in this disclosure are merely structural schematic diagrams, and one aspect of this disclosure is not limited to the shapes or values ​​shown in the drawings.

[0121] The ordinal numbers “first,” “second,” and “third” used in this specification are used to avoid confusion among the constituent elements, not to limit their quantity.

This is solely for the purpose of facilitating the description and simplification, and does not imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this disclosure. The positional relationships of the constituent elements may be appropriately varied depending on the direction in which each constituent element is described. Therefore, the use of terms not limited to those described in the specification may be appropriately replaced as needed.

[0123] In this specification, unless otherwise expressly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they may refer to a fixed connection, a detachable connection, or an integral connection; a mechanical connection or an electrical connection; a direct connection, an indirect connection via an intermediate component, or a connection within two components. Those skilled in the art will understand the specific meaning of these terms in this disclosure based on the specific circumstances.

[0124] In this specification, "electrical connection" includes the situation where components are connected together by elements having a certain electrical function. There are no particular limitations on the term "elements having a certain electrical function," as long as they enable the transmission and reception of electrical signals between the connected components. Examples of "elements having a certain electrical function" include not only electrodes and wiring, but also switching elements such as transistors, resistors, inductors, capacitors, and other elements having one or more functions.

[0125] In this specification, "parallel" refers to a state in which two straight lines form an angle of -10° or more and less than 10°, and therefore can include a state in which the angle is -5° or more and less than 5°. Similarly, "perpendicular" refers to a state in which two straight lines form an angle of 80° or more and less than 100°, and therefore can include a state in which the angle is 85° or more and less than 95°.

Small deformations due to tolerances are possible, as are chamfers, curved edges, and other variations.

[0128] In this disclosure, “about” means a value that is not strictly limited and allows for process and measurement errors.

[0129] In this disclosure, “thickness” refers to the dimension of the film layer in the direction perpendicular to the substrate.

[0130] In this disclosure, "transmittance" refers to the ability of light to pass through a medium, and is the percentage of luminous flux passing through a transparent or translucent body relative to the incident luminous flux.

[0131] In mobile terminals such as smartphones, laptops, and automotive windows, as well as in wireless applications such as microsatellites, smart buildings, smart windows, smart wearable devices, and in-vehicle communication equipment, miniaturization and thin-film technology of various microwave communication devices, such as transmission lines, waveguides, and antennas, have become a development trend. The thin-film transformation of traditional large-size microwave devices facilitates conformal structure design, reducing the weight and cost of communication systems.

[0132] In recent years, mobile terminals (such as smartphones) have been developing towards ultra-thin designs, full-screen displays, and compatibility with a range of communication functions, including 5G, 4G, 3G, 2G, Wi-Fi, NFC, Bluetooth, GPS, BeiDou Navigation Satellite System, and wireless charging. This has severely limited the design space available for antennas. Furthermore, existing mobile terminal antenna structures cannot simultaneously cover multiple 5G millimeter wave frequency bands. In addition, 5G millimeter wave propagation loss is significant, requiring antenna arrays to be deployed to ensure antenna gain, necessitating more space for antenna arrangement. These contradictions have objectively driven the demand for on-screen antennas. By designing on-screen antennas with good concealment performance, the aforementioned space constraints can be alleviated. Currently, transparent oxide conductive materials such as indium tin oxide (ITO), multilayer film materials of metals and conductive oxides, or metal mesh films are commonly used to achieve transparent antenna designs.

[0133] In related technologies, on-screen antennas for mobile terminals are mainly constructed by building antennas on a flexible film and then bonding the flexible film to the screen of the mobile terminal. This bonding process cannot achieve the precise alignment required in semiconductor manufacturing, resulting in noticeable occlusion of individual pixels on the screen by the antenna, easily producing occlusion patterns and moiré stripes. Furthermore, because the metal lines forming the antenna in the antenna area block some incident light, the transmittance of the antenna area and the non-antenna area on the screen is inconsistent. To make the transmittance of the non-antenna area as consistent as possible with that of the antenna area and to passivate the visual effect of inconsistent transmittance, a similar grid pattern structure is usually constructed in the non-antenna area of ​​the screen. This reduces the overall transmittance of the screen by 5% to 20%. If the antenna is integrated directly onto the screen encapsulation layer (such as the encapsulation layer of OLED), the touch panel (TP) can be integrated on the screen encapsulation layer. Although precise alignment in semiconductor processes can be used, the encapsulation layer is only 10 micrometers away from the metal cathode in the screen. According to the microstrip antenna patch radiation theory, the radiation efficiency is only about 2.8%. Because the radiation efficiency is too low, it is basically not feasible to directly use semiconductor photolithography alignment process to make antennas.

[0134] This disclosure provides an antenna that may include a first conductive layer, a dielectric layer, and a second conductive layer stacked together.

[0135] The first conductive layer has at least one slot;

[0136] The second conductive layer includes at least one conductive structure, which is a comb-shaped structure. The conductive structure includes a first conductive element and a plurality of second conductive elements. The first conductive element forms the back of the comb-shaped structure, and the plurality of second conductive elements form the teeth of the comb-shaped structure.

[0137] At least one comb-shaped conductive structure is provided corresponding to at least one slot. In the at least one conductive structure, the first ends of a plurality of second conductive elements are connected to a first conductive element, and the orthographic projection of the second ends of at least a portion of the second conductive elements on the dielectric layer is located within the range of the orthographic projection of the slot on the dielectric layer.

[0138] The antenna provided in this embodiment includes a first conductive layer, a dielectric layer, and a second conductive layer stacked together. A slot is formed in the first conductive layer, and a comb-shaped conductive structure is formed in the second conductive layer. The conductive structure includes a first conductive element and a plurality of second conductive elements. The first conductive element forms the back of the comb-shaped structure, and the plurality of second conductive elements form the teeth of the comb-shaped structure. By forming a slot in the first conductive layer, and ensuring that the orthographic projection of the second end of at least a portion of the second conductive elements in the comb-shaped conductive structure on the second conductive layer is within the range of the orthographic projection of the slot in the dielectric layer, the radiation efficiency of the antenna is greatly improved.

[0139] Figure 1a This is a schematic diagram of a planar structure of an antenna, as an exemplary embodiment of the present disclosure. Figure 1b for Figure 1a A cross-sectional structural diagram of the LL position in the middle. Figure 1d This is a schematic diagram of a planar structure of another antenna, as shown in an exemplary embodiment of this disclosure. Figure 1a , Figure 1b and Figure 1d As shown, the antenna may include a first conductive layer 11, a dielectric layer 12, and a second conductive layer 13 stacked together; wherein:

[0140] The first conductive layer 11 is provided with at least one slot 111;

[0141] The second conductive layer 13 may include at least one conductive structure 130, the conductive structure 130 being a comb-like structure, the conductive structure 130 may include a first conductive element 131 and a plurality of second conductive elements 132, the first conductive element 131 forming the back of the comb-like structure, and the plurality of second conductive elements 132 forming the teeth of the comb-like structure.

[0142] At least one conductive structure 130 is provided corresponding to at least one slot 111. In the at least one conductive structure 130, the first ends of a plurality of second conductive elements 132 are connected to the first conductive element 131. The orthographic projection of the second ends of at least a portion of the second conductive elements 132 on the dielectric layer 11 is located within the range of the orthographic projection of the slot 111 on the dielectric layer 11.

[0143] exist Figure 1a In the structure shown, the orthographic projection of the second end of all the second conductive elements 132 onto the dielectric layer 11 is within the range of the orthographic projection of the slot 111 onto the dielectric layer 11.

[0144] exist Figure 1d In the structure shown, the orthographic projection of a portion of the second end of the second conductive element 132 onto the dielectric layer 11 falls within the range of the orthographic projection of the slot 111 onto the dielectric layer 11; the orthographic projection of the second end of another portion of the second conductive element 132 onto the dielectric layer 11 does not fall within the range of the orthographic projection of the slot 111 onto the dielectric layer 11, i.e. Figure 1d The orthographic projection of the second conductive element 132 in another part on the dielectric layer 11 does not overlap with the orthographic projection of the slot 111 on the dielectric layer 11.

[0145] In an exemplary embodiment, a dielectric material is provided in the slot 111, and the dielectric material in the slot 111 and the dielectric layer 12 are formed using the same process. In this embodiment, forming the dielectric material in the slot 111 and the dielectric layer 12 using the same process simplifies the process and reduces the cost of antenna fabrication. In this embodiment, the dielectric material in the slot 111 is not limited to being the same as the dielectric material in the dielectric layer 12; a different dielectric material can be used. For example, the dielectric material in the slot 111 can have a dielectric constant greater than that of the dielectric layer 12. In this embodiment, the dielectric material in the slot 111 is not limited to being formed using the same process as the dielectric layer 12; a different process can be used.

[0146] In an exemplary embodiment, the width W2 of the slot 111 is 40 micrometers to 110 micrometers, the length L4 of the slot 111 in the arrangement direction (Y direction) of the plurality of second conductive elements 132 is 3.6 millimeters to 5.0 millimeters, and in the arrangement direction of the plurality of second conductive elements 132, the orthographic projection of the slot 111 on the dielectric layer 12 exceeds the orthographic projection of the plurality of second conductive elements 132 on the dielectric layer 12, such as... Figures 1a-1dAs shown, in the second direction Y, the upper end of the orthographic projection of the slot 111 onto the dielectric layer 12 is higher than the upper end of the orthographic projection of the plurality of second conductive elements 132 onto the dielectric layer 12, and the lower end of the orthographic projection of the slot 111 onto the dielectric layer 12 is lower than the lower end of the orthographic projection of the plurality of second conductive elements 132 onto the dielectric layer 12. In this embodiment of the present disclosure, the orthographic projection of the slot 111 onto the dielectric layer 12 exceeds the orthographic projection of the plurality of second conductive elements 132 onto the dielectric layer 12, which allows the orthographic projection of the second ends of all the first sub-conductive elements 1321 among the second conductive elements 132 onto the dielectric layer 12 to fall within the range of the slot 111, thereby allowing the electromagnetic wave energy on the first sub-conductive elements 1321 to be transmitted out from the slot 111.

[0147] In an exemplary implementation, such as Figure 1a , Figure 1c , Figures 2a-2e As shown, the first conductive element 131 includes: a first side A1 and a second side A2 arranged opposite to each other, and a third side A3 and a fourth side A4 arranged opposite to each other. The second conductive element 132 is located on the first side A1 or the second side A2 of the first conductive element 131. A plurality of second conductive elements 132 are arranged along the second direction (Y direction).

[0148] In an exemplary embodiment, the first conductive element 131 may employ a mesh-like structure, such as... Figure 1a As stated; or as described Figure 1c As shown, the first conductive element 131 can be a non-mesh structure, for example, the first conductive element 131 can be a strip structure.

[0149] In an exemplary implementation, such as Figures 2a-2e As shown, the second conductive element 132 includes a first sub-conductive element 1321 and a second sub-conductive element 1322, wherein the first sub-conductive element 1321 and the second sub-conductive element 1322 are alternately arranged along the second direction (Y direction);

[0150] The plurality of first sub-conductive elements 1321 can be a plurality of first conductive lines a1 extending along a first direction (X direction), and the plurality of first conductive lines a1 are arranged along a second direction (Y direction);

[0151] The plurality of second sub-conductive elements 1322 can be a plurality of second conductive lines a2 extending along a first direction (X direction), and the plurality of second conductive lines a2 are arranged along a second direction (Y direction);

[0152] The length of the first sub-conductive element 1321 along the first direction (X direction) is greater than the length of the second sub-conductive element 1322 along the first direction (X direction), and the orthographic projection of the second end of the first sub-conductive element 1321 on the dielectric layer 12 is within the range of the orthographic projection of the slot 111 on the dielectric layer 12, and the orthographic projection of the second end of the second sub-conductive element 1322 on the dielectric layer 111 does not overlap with the orthographic projection of the slot 111 on the dielectric layer 12.

[0153] In an exemplary embodiment, the first conductive line a and the second conductive line a2 are hollow or solid structures, that is, the first sub-conductive element 1321 and the second sub-conductive element 1322 are hollow or solid structures.

[0154] In an exemplary embodiment, the first sub-conductive element 1321 and the second sub-conductive element 1322 are alternately arranged along the second direction (Y direction), as follows: Figure 2c As shown, a first conductive line a1 (i.e., a first sub-conductive element 1321) and a second conductive line a2 (i.e., a second sub-conductive element 1322) are alternately arranged along the second direction (Y direction). In embodiments of this disclosure, the arrangement is not limited to the alternation of a first sub-conductive element 1321 and a second sub-conductive element 1322 along the second direction Y; it can be as follows: Figure 2e As shown, two first sub-conductive elements 1321 and two second sub-conductive elements 1322 are alternately arranged along the second direction (Y direction); or as... Figure 2a , Figure 2b , Figure 2d As shown, in a comb-shaped conductive structure 130, one or more first sub-conductive elements 1321 and one or more second sub-conductive elements 1322 are alternately arranged along a second direction (Y direction).

[0155] In an exemplary embodiment, the comb-shaped conductive structure 130 is an artificial surface plasmon resonance (ASPRING) structure. In this embodiment, the ASPRING structure can be an ultra-thin comb-shaped conductive structure. The first conductive structure 11 serves as a metal ground. The ultra-thin comb-shaped conductive structure has only one layer of metal film to tightly confine electromagnetic energy. In many applications, the metal ground (first conductive structure 11) and the comb-shaped conductive structure are required to be very close. A large portion of the electromagnetic energy is confined between the metal ground (first conductive structure 11) and the comb-shaped conductive structure, similar to a microstrip transmission line. The small distance between the metal ground and the comb-shaped conductive structure leads to low antenna radiation efficiency. In this embodiment, a slot 111 is provided on the first conductive layer 11, such that the orthographic projection of at least a portion of the second end of the second conductive element 132 onto the dielectric layer 12 lies within the range of the orthographic projection of the slot 111 onto the dielectric layer 11. The electromagnetic wave energy projected onto the comb teeth within the slot can be transmitted out through the slot and is not confined between the metal ground and the comb-shaped conductive structure, thereby improving the antenna radiation efficiency.

[0156] In an exemplary embodiment, the second conductive layer 13 is a transparent conductive layer, which can increase transparency. The application of the antenna in the display device can reduce the obstruction of the screen in the display device and increase the light transmittance.

[0157] In an exemplary embodiment, each comb-shaped conductive structure includes at least one positive radiation field and at least one negative radiation field. The positive radiation field of the antenna corresponds to the region of the first sub-conductive element 1321, and the negative radiation field of the antenna corresponds to the region of the second sub-conductive element 1322; or, the negative radiation field of the antenna corresponds to the region of the first sub-conductive element 1321, and the positive radiation field of the antenna corresponds to the region of the second sub-conductive element 1322.

[0158] In this embodiment, by alternating the arrangement of the first sub-conductive element 1321 and the second sub-conductive element 1322, electromagnetic waves will periodically form positive and negative radiation fields along the direction of the second conductive element 132 as they travel along the comb-like conductive structure. If both the positive and negative radiation fields are radiated into free space through the slot, the total far-field radiation field may cancel each other out, reducing the radiation efficiency to some extent. In this embodiment, the first sub-conductive element 1321 (i.e., the long teeth of the comb-like structure) and the second sub-conductive element 1322 (i.e., the short teeth of the comb-like structure) are alternately arranged, and only the projection of the second end of the first sub-conductive element 1321 falls into the slot 111, while the projection of the second end of the second sub-conductive element 1322 does not fall into the slot 111. In designing the comb-shaped conductive structure 130 of the antenna, two different directional radiation fields (including positive and negative radiation fields) are aligned with the regions corresponding to the first sub-conductive element 1321 and the second sub-conductive element 1322, respectively. Because the long and short teeth have different radiation capabilities within the slots, coherent enhancement rather than destructive interaction occurs in the far field, thereby further enhancing the antenna's radiation efficiency. For example... Figure 3 As shown, C1 is Figures 2a-2e The curve shown illustrates the radiation efficiency versus frequency relationship of an antenna with slotted design and alternating first sub-conductive element 1321 and second sub-conductive element 1322. C2 represents... Figure 1a The curves shown are the radiation efficiency versus frequency for the slotted antenna (C3) and the unslotted antenna (C4). Figure 3 As shown, in the antenna structure at a frequency of 28 GHz, the antenna with slots (corresponding to curve C2) has a radiation efficiency that is about 1.6 times higher than that without slots (corresponding to curve C2); and the antenna with slots and alternating long and short teeth (corresponding to curve C1) has a radiation efficiency that is more than 10 times higher than that without slots (corresponding to curve C2).

[0159] In this embodiment of the disclosure, the radiation efficiency of an antenna refers to the ratio of the power transmitted to the antenna to the power radiated by the antenna.

[0160] In an exemplary embodiment, when the comb-shaped conductive structure employs an artificial surface plasmon resonance structure, the conductive structure 130 is arranged along the direction of the plurality of second conductive elements 132. Figure 2a The dimension of the conductive structure 130 in the Y direction is 1 mm to 2 mm, and the conductive structure 130 extends along the direction of the second conductive element. Figure 2a The size of the antenna (in the X direction) is 1 mm to 2 mm. For example, the size of the antenna can be 1.5 mm * 1.5 mm, that is, the conductive structure 130 is arranged along the direction of the plurality of second conductive elements 132 (in the X direction). Figure 2aThe dimension in the Y direction is 1.5 mm, and the conductive structure 130 extends along the direction of the second conductive element. Figure 2a The antenna (in the X direction) is 1.5 mm in size. This size antenna operates at a frequency of approximately 28 GHz and transmits or receives electromagnetic waves with wavelengths of 10 to 12 mm.

[0161] In this embodiment of the disclosure, in each comb-shaped conductive structure 130, the intensity of the electromagnetic wave decreases exponentially along the direction of the comb teeth. Figure 2a An evanescent wave is formed in the X direction, while along the direction of the comb teeth arrangement ( Figure 2a The surface plasmon resonance (SPR) structure propagates along the Y-direction, forming a surface plasmon wave (a type of electromagnetic surface wave) whose electromagnetic energy is confined to the tips of the comb teeth. The wave vector of the surface plasmon wave propagating along the Y-direction is much larger than that in a vacuum. Utilizing this property, the size of the antenna and the device carrying it can be compressed, thus enabling the miniaturization of antennas and the devices carrying them. Artificial surface plasmon resonance structures (SPRs) leverage their advantages to reduce antenna size. While ordinary metal structures can be used as antennas, they are relatively large. On mobile phone screens or other small electronic device screens, it is necessary to minimize the antenna size to reduce its impact on display and touch layer performance. For example, a typical 28GHz patch antenna is around 3mm × 3mm, while an SPR antenna can be compressed to around 1.5mm × 1.5mm, significantly reducing the antenna size and saving space in the electronic device with the antenna, thus minimizing the overall size of the device.

[0162] In an exemplary embodiment, the dimension W1 (width of the first conductive line a1 and the second conductive line a2) of the first sub-conductive element 1321 (i.e., the first conductive line a1) and the second sub-conductive element 1322 (i.e., the second conductive line a2) along the second direction Y is 0.01 mm to 0.12 mm; the length L1 of the first sub-conductive element 1321 (i.e., the first conductive line a1) along the first direction X is 0.98 mm to 1.3 mm; the length L2 of the second sub-conductive element 1322 (i.e., the second conductive line a2) along the first direction X is 0.8 mm to 0.95 mm; and the distance H1 between the centers of two adjacent second conductive elements 132 is 0.02 mm to 0.4 mm.

[0163] In an exemplary embodiment, the antenna further includes a feed line 133, which is disposed on the third side A3 or the fourth side A4 of the first conductive element 131; or the feed line 133 is disposed on the comb teeth located at the ends of the second conductive element 132, for example, the feed line 133 is disposed on the comb teeth at both ends of the second conductive element 132 along the second direction Y, such as... Figure 2dAs shown, the feed line 133 can be disposed on the comb teeth at the lower end of the second conductive element 132 along the second direction Y.

[0164] In an exemplary embodiment, the width W3 of the feed line 133 is 20 to 60 micrometers.

[0165] In an exemplary embodiment, the sum of the lengths of the conductive structure 130 and the feed line 133 along the arrangement direction of the plurality of second conductive elements 132 is 2 mm to 3.5 mm. For example, the sum of the lengths of the conductive structure 130 and the feed line 133 along the arrangement direction of the plurality of second conductive elements 132 is 2.7 mm.

[0166] In an exemplary implementation, such as Figure 4a and Figure 4b As shown, at least one slot 111 includes a first slot 1111 and a second slot 1112; at least one conductive structure 130 includes a first conductive structure 1301 and a second conductive structure 1302; the first conductive element 1321 in the first conductive structure 1301 and the first conductive element 1321 in the second conductive structure 1302 are connected.

[0167] In an exemplary embodiment, Figure 4a and Figure 4b In the structure shown, the arrangement direction of the plurality of second conductive elements 132 in the first conductive structure 1301 is parallel to the arrangement direction of the plurality of second conductive elements 132 in the second conductive structure 1302.

[0168] The first sub-conductive element 1321 in the first conductive structure 1301 and the first sub-conductive element 1321 in the second conductive structure 1302 are symmetrically arranged with respect to the first conductive structure 1301 and the second conductive structure 1302 along the centerline of the second direction (Y direction). The second sub-conductive element 1321 in the first conductive structure 1301 and the second sub-conductive element 1322 in the second conductive structure 1302 are symmetrically arranged with respect to the first conductive structure 1301 and the second conductive structure 1302 along the centerline of the second direction (Y direction).

[0169] In an exemplary embodiment, Figures 4a to 4d As shown, the antenna also includes a first connecting line 141. The first conductive element 1321 in the first conductive structure 1301 and the first conductive element 1321 in the second conductive structure 1302 are arranged in parallel and connected by the first connecting line 141. The first connecting line 141 is configured to connect two close ends of the comb back of the first conductive structure 1301 and the comb back of the second conductive structure 1302.

[0170] In an exemplary implementation, such as Figures 4a to 4dAs shown, feed line 133 is connected to first connecting line 141. Feed line 133 divides first connecting line 141 into first sub-connecting line 1411 and second sub-connecting line 1412. First sub-connecting line 1411 is located between feed line 133 and first conductive structure 1301, and second sub-connecting line 1412 is located between feed line 133 and second conductive structure 1302. The length of first connecting line 141 is the wavelength of the electromagnetic wave transmitted or received by the antenna. In an exemplary embodiment, the difference between the length of first sub-connecting line 1411 and the length of second sub-connecting line 1412 is 0.4 to 0.6 times the wavelength of the electromagnetic wave. For example, in... Figure 4a and Figure 4b In the structure shown, the length of the first sub-connecting line 1411 is less than the length of the second sub-connecting line 1412. The difference between the lengths of the first sub-connecting line 1411 and the second sub-connecting line can be 0.5 times the wavelength of the electromagnetic wave transmitted or received by the antenna. Figure 4c and Figure 4d In the structure shown, the length of the first sub-connecting line 1411 can be greater than the length of the second sub-connecting line 1412, and the difference between the length of the second sub-connecting line 1412 and the length of the first sub-connecting line 1411 can be 0.4 to 0.6 times the wavelength of the electromagnetic wave transmitted or received by the antenna. For example, the difference between the length of the second sub-connecting line 1412 and the length of the first sub-connecting line 1411 can be 0.5 times the wavelength of the electromagnetic wave transmitted or received by the antenna.

[0171] In an exemplary implementation, such as Figure 4b and Figure 4d As shown, the longer of the first sub-connecting line 1411 and the second sub-connecting line 1412 can be a polygonal line. In this embodiment of the present disclosure, setting the longer of the first sub-connecting line 1411 and the second sub-connecting line 1412 to a polygonal line can reduce the distance between the first conductive structure 1301 and the second conductive structure 1302, thereby reducing the size of the antenna.

[0172] exist Figure 4a and Figure 4c In the structure shown, the longer of the first sub-connecting line 1411 and the second sub-connecting line 1412 can be a straight line.

[0173] In an exemplary implementation, such as Figure 5a and Figure 5b As shown, the arrangement direction of the plurality of second conductive elements 132 in the first conductive structure 1301 is parallel to the arrangement direction of the plurality of second conductive elements 132 in the second conductive structure 1302; among the plurality of second conductive elements 132, the first sub-conductive element 1321 constitutes the long teeth of the comb structure 130, and the second sub-conductive element 1322 constitutes the short teeth of the comb structure 130.

[0174] The first sub-conductive element 1321 in the first conductive structure 1301 and the second sub-conductive element 1321 in the second conductive structure 1302 are correspondingly arranged along the first direction (X direction), forming a complementary structure of long and short teeth in the first direction X; the second sub-conductive element 1322 in the first conductive structure 1301 and the first sub-conductive element 1321 in the second conductive structure 1302 are correspondingly arranged along the first direction (X direction), forming a complementary structure of long and short teeth in the first direction X.

[0175] In an exemplary embodiment, Figure 5a and Figure 5b In the structure shown, the antenna also includes a first connecting line 141. The first conductive element 1321 in the first conductive structure 1301 and the first conductive element 1321 in the second conductive structure 1302 are arranged in parallel and connected by the first connecting line 141. The first connecting line 141 is configured to connect two close ends of the comb back of the first conductive structure 1301 and the comb back of the second conductive structure 1302.

[0176] In an exemplary implementation, such as Figure 5a As shown, feed line 133 is connected to first connecting line 141. Feed line 133 divides first connecting line 141 into first sub-connecting line 1411 and second sub-connecting line 1412. First sub-connecting line 1411 is located between feed line 133 and first conductive structure 1301, and second sub-connecting line 1412 is located between feed line 133 and second conductive structure 1302. The length of first connecting line 141 can be the wavelength of electromagnetic waves transmitted or received by the antenna, and the lengths of first sub-connecting line 1411 and second sub-connecting line 1412 can be equal.

[0177] In an exemplary implementation, such as Figure 5b As shown, the first conductive element 1321 in the first conductive structure 1301 and the first conductive element 1321 in the second conductive structure 1302 are the same conductive element; the second conductive element 1322 of the first conductive structure 1301 is located on the first side A1 of the first conductive element 1321, and the second conductive element 1322 of the second conductive structure 1322 is located on the second side A2 of the first conductive element. Figure 5b In the structure shown, the first conductive element 1321 in the first conductive structure 1301 and the first conductive element 1321 in the second conductive structure 1302 are the same conductive element, which can reduce the size of the antenna.

[0178] In exemplary embodiments of this disclosure, such as Figure 5b As shown, the antenna may also include at least one bridge connection line 140 connecting multiple connection lines 14, and the at least one bridge connection line 140 and the multiple connection lines 14 form a grid structure.

[0179] In an exemplary implementation, such as Figures 6a to 6b As shown, the angle between the first conductive element 1321 in the first conductive structure 1301 and the first conductive element 1321 in the second conductive structure 1302 is greater than 0 degrees and less than 180 degrees. The arrangement direction of the plurality of second conductive elements 132 in the first conductive structure 1301 forms a first angle F1 with the arrangement direction of the plurality of second conductive elements 132 in the second conductive structure 1302, or the first conductive element 1321 in the first conductive structure 1301 and the first conductive element 1321 in the second conductive structure 1302 forms a first angle F1. The first angle F1 is greater than 0 degrees and less than 180 degrees. For example, the first angle F1 can be 30 degrees, 60 degrees, 90 degrees, or 120 degrees.

[0180] In an exemplary embodiment, as such Figures 6a to 6c In the structure shown, the antenna also includes a first connecting line 141. The first conductive element 1321 in the first conductive structure 1301 and the first conductive element 1321 in the second conductive structure 1302 are connected by the first connecting line 141. The first connecting line 141 is configured to connect two close ends of the comb back of the first conductive structure 1301 and the comb back of the second conductive structure 1302.

[0181] In an exemplary embodiment, a feed line 133 is disposed on a first connecting line 141, dividing the first connecting line 141 into a first sub-connecting line 1411 and a second sub-connecting line 1412. The first sub-connecting line 1411 is located between the feed line 133 and the first conductive structure 1301, and the second sub-connecting line 1412 is located between the feed line 133 and the second conductive structure 1302. The length of the first connecting line 141 is the wavelength of the electromagnetic wave transmitted or received by the antenna, and the difference between the length of the first sub-connecting line 1411 and the length of the second sub-connecting line 1412 is 0.4 to 0.6 times the wavelength of the electromagnetic wave. For example, in Figure 6a and Figure 6b In the structure shown, the length of the first sub-connecting line 1411 is less than the length of the second sub-connecting line 1412. The difference between the lengths of the first sub-connecting line 1411 and the second sub-connecting line can be 0.5 times the wavelength of the electromagnetic wave transmitted or received by the antenna. Figure 6c In the structure shown, the length of the first sub-connecting line 1411 is greater than the length of the second sub-connecting line 1412. The difference between the lengths of the first sub-connecting line 1411 and the second sub-connecting line can be 0.5 times the wavelength of the electromagnetic wave transmitted or received by the antenna. In an exemplary embodiment, the longer of the first sub-connecting line 1411 and the second sub-connecting line 1412 is a polygonal line, such as... Figure 6cAs shown, setting the first sub-connecting line 1411 as a broken line can reduce the distance between the first conductive structure 1301 and the second conductive structure 1302, thereby reducing the size of the antenna.

[0182] In another exemplary implementation, such as Figure 6d and Figure 6e As shown, the feed line 133 is disposed at the end of the second conductive structure 1302 away from the first conductive structure 1301, or the feed line 133 is disposed at the end of the first conductive structure 1301 away from the second conductive structure 1302, and the length of the first connecting line 141 is 0.7 to 0.8 times the wavelength of the electromagnetic wave transmitted or received by the antenna.

Figure 8c In the structure shown, the length of the first sub-connecting line 1441 is greater than the length of the second sub-connecting line 1442. The first sub-connecting line 1441 is set as a broken line, which can reduce the distance between the fifth conductive structure 1305 and the sixth conductive structure 1306, thereby reducing the size of the antenna.

[0204] This disclosure also provides a display substrate, such as... Figures 9 to 11 As shown, the display substrate may include a display area AA and a non-display area ND. The display area AA is provided with a plurality of sub-pixels P arranged in an array.

[0217] In an exemplary implementation, such as Figure 11 As shown, the orthographic projection of the touch trace 1071 on the substrate and the orthographic projection of the second conductive layer 13 in the antenna on the substrate can partially overlap.

[0218] In an exemplary embodiment, as in an exemplary embodiment, such as Figure 9As shown, the light-emitting structure layer may include an anode structure layer 102, a light-emitting layer 103, and a cathode structure layer 104 stacked sequentially. The driving structure layer 101 (which may include an array substrate row driving circuit layer 1011, a planarization insulating layer 1012, and a pixel driving circuit layer 1013), the anode structure layer 102, and the light-emitting layer 103 (which may include a pixel structure layer 1031 and a pixel definition layer 1032) may extend to the non-display area ND.

[0219] The orthographic projection of the cathode structure layer 104 on the plane of the encapsulation layer 105 overlaps with the orthographic projection of the power line 106 on the plane of the encapsulation layer 105, and the orthographic projection of the cathode structure layer 104 on the plane of the encapsulation layer 105 does not overlap with the orthographic projection of the slot 111 on the plane of the encapsulation layer 105.

[0220] In an exemplary implementation, such as Figure 10 As shown, the orthographic projections of the cathode structure layer 104 and the touch layer 107 on the substrate 100 overlap with the orthographic projection of the low-level power line 1061 on the substrate 100, and the orthographic projections of the cathode structure layer 104 and the touch structure layer 107 on the plane of the encapsulation layer 105 do not overlap with the orthographic projection of the slot 111 on the plane of the encapsulation layer 105.

[0221] In this embodiment of the disclosure, the thickness of the low-level power line 1061 ( Figure 9-10 The relatively thick thickness of the low-level power line 1061 (located in the non-display area along the Z-direction) allows for good conductivity of the low-level power line 1061, even with a narrow bezel on the display substrate. This ensures uniform conduction of the pixel current supplied by the low-level power line 1061 to different locations on the display substrate. For example, the thickness of the low-level power line 1061 can be greater than or equal to 1 micrometer. In this embodiment, the low-level power line 1061 can be an ELVSS signal line in the display substrate. In this embodiment, the non-display area ND of the display substrate can be understood as the bezel of the display substrate. Generally, a narrower bezel is better for visual effect, and the width of the low-level power line 1061 ( Figure 9-10 The dimension of the medium power line 106 along the X direction does not increase, the bezel of the display substrate does not increase, and the thickness of the low-level power line 1061 ( Figure 9-10 Increasing the size of the power line 106 along the Z direction allows for uniform conduction of the pixel circuitry supplied to the display substrate without increasing the bezel of the display substrate.

In this embodiment, the pixel structure layer 1031 can be an organic light-emitting layer. The pixel structure layer 1031 may include a stacked hole injection layer (HIL), a hole transport layer (HTL), an electron block layer (EBL), an emitting layer (EML), a hole block layer (HBL), an electron transport layer (ETL), and an electron injection layer (EIL).

[0224] In this embodiment of the disclosure, a pixel driving circuit can be provided in the portion of the driving structure layer 101 located in the display area AA, and an array substrate row driving (Gate Driver on Array, abbreviated as GOA) circuit can be provided in the portion of the driving structure layer 101 located in the non-display area ND.

[0225] In an exemplary implementation, such as Figure 11 As shown, Figure 9 and Figure 10 The diagram shows a partial planar structure of the cross-sectional structure. The second conductive layer 13 in the antenna can enclose at least one conductive structure 130. The conductive structure 130 is a comb-shaped structure. The conductive structure 130 includes a first conductive element 131 and a plurality of second conductive elements 132. The first conductive element 131 forms the back of the comb-shaped structure, and the plurality of second conductive elements 132 form the teeth of the comb-shaped structure.

[0226] The first conductive element 131 is located in the display area AA, the first ends of a plurality of second conductive elements 132 are located in the display area AA, the second ends of a plurality of second conductive elements 132 are located in the non-display area ND, the first ends of a plurality of second conductive elements 132 are connected to the first conductive element 131, and the orthographic projection of the second ends of at least a portion of the second conductive elements 132 on the substrate 100 is located within the range of the orthographic projection of the slot 111 on the substrate 100.

[0227] In an exemplary embodiment, the second conductive layer 13 is disposed on the display area AA and the non-display area ND of the display substrate, such as... Figure 11 As shown, the first conductive element 131 and the second conductive element 132 can be configured as solid structures; in the display area AA, the first conductive element 131 and the second conductive element 132 are disposed in the interval area of ​​the plurality of sub-pixels P, and the orthographic projection of the first conductive element 131 and the second conductive element 132 on the substrate 100 does not overlap with the orthographic projection of the plurality of sub-pixels P on the substrate 100.

[0228] In an exemplary implementation, such as Figures 12a to 12d As shown, Figure 9 and Figure 10 The schematic diagrams of several other partial planar structures shown in the cross-sectional structure indicate that at least one of the first conductive element 131 and the second conductive element 132 is a hollow structure with a cutout structure M. The orthographic projections of the first conductive element 131 and the second conductive element 132 with the cutout structure M on the substrate 100 overlap with the orthographic projections of some sub-pixels among the multiple sub-pixels P on the substrate 100, and the overlapping area is located within the range of the orthographic projection of the cutout structure M on the substrate 100.

[0229] In an exemplary implementation, such as Figure 12e As shown, Figure 9 and Figure 10 Another planar structure diagram shows that the first guiding element 131 is configured as a grid structure, the grid lines of the grid structure are set in the interval area between adjacent sub-pixels p, and the orthographic projection of the grid lines of the grid structure on the substrate 100 does not overlap with the orthographic projection of the multiple sub-pixels p on the substrate 100.

[0230] exist Figures 11 to 12e In the structure shown, the multiple sub-pixels P include at least a first pixel P1, a second pixel P2, and a third pixel P3, and adjacent first pixels P1, second pixels P2, and third pixels P3 constitute a pixel unit H.

[0231] exist Figures 12a to 12d In the structure shown, in the structure where the antenna is set on the display substrate, the first conductive element 131 and the second conductive element 132 in the comb-shaped conductive structure are set as a hollow structure in the area corresponding to the multiple sub-pixels P in the display area AA. Figure 12e The first conductive element 131 is configured as a mesh structure. The hollow structure M and the mesh structure can avoid blocking the pixel P, and there is no need to passivate the non-antenna area in order to make the light transmittance of the antenna area and the non-antenna area consistent. This greatly improves the light transmittance of the display substrate and avoids the defect of inconsistent light transmittance between the antenna area and the non-antenna area.

[0232] exist Figure 11 In the structure shown, in the structure where the antenna is set on the display substrate, the first conductive element 131 and the second conductive element 132 in the comb-shaped conductive structure correspond to the areas of multiple pixels P in the display area AA. The first conductive element 131 and the second conductive element 132 correspond to the interval areas of multiple pixels P. This can also avoid blocking the pixels P, and it is not necessary to passivate the non-antenna area in order to make the light transmittance of the antenna area and the non-antenna area consistent. This greatly improves the light transmittance of the display substrate, and there is no defect of inconsistent light transmittance between the antenna area and the non-antenna area.

[0233] exist Figures 11-12e In the structure, the comb-shaped conductive structure 130 can be set as a transparent structure, so that the first conductive element 131 and the second conductive element 132 can be set more flexibly among multiple sub-pixels P, and the sub-pixels P will not be obstructed.

[0234] In the embodiments disclosed herein, such as Figures 11-12e The structure can be configured based on the arrangement of multiple sub-pixels P and the structure of the comb-like conductive structure 130 in the antenna. For example, a second conductive element 132 can be provided between two adjacent pixels P. Figure 11 As shown; or, the second conductive element 132 and the first conductive element 131 can be configured as a hollow structure, with the hollow structure M corresponding to one or more sub-pixels P, and one or more sub-pixels P corresponding to two adjacent second conductive elements 132, such as... Figures 12a-12d As shown.

[0235] In an exemplary embodiment, the display substrate may be provided with one or more comb-shaped conductive structures 130, such as... Figure 13 As shown, a comb-shaped conductive structure 130 can be disposed on the display substrate of the display device. Figure 13 The image shows a linearly polarized radiating antenna. (For example...) Figure 14 As shown, in the structure of the display substrate having multiple comb-shaped conductive structures 130, adjacent comb-shaped conductive structures are connected by an antenna connection line 1401, which is located in the non-display area ND. Figure 14 The two comb-shaped conductive structures 130 shown constitute a circularly polarized radiating antenna.

[0236] In an exemplary implementation, such as Figure 14 As shown, the closely spaced comb teeth in two adjacent comb-shaped conductive structures 130 are connected by an antenna connection line 1401, i.e. Figure 14 The comb teeth at one end of the two comb-shaped conductive structures 130 that are close to each other are connected by an antenna connection line 1401.

[0237] In the embodiments disclosed herein, such as Figure 9-10 , Figure 13-16 In the structure shown, the region where the thickness of the low-level power line with the slot 111 along the first direction X is greater than the thickness of the low-level power line without the slot 111 can be used as a compensation structure for the low-level power line.

[0238] In an exemplary implementation, such as Figure 13 and Figure 14 As shown, a compensation structure 15 with the same volume as the slot 111 is provided along the width direction of the low-level power line 1061. The compensation structure 15 is provided on one or both sides of the power line 106.

[0239] exist Figures 13-15 In the structure shown, the compensation structure 15 is disposed on one side of the low-level power line 1061, and the width of each compensation structure is substantially the same as the width of the slot 111. Figure 16 In the structure shown, the compensation structure 15 is disposed on both sides of the low-level power line 1061, and the width of each compensation structure is approximately 0.5 times the width of the slot 111.

[0240] In this embodiment, by providing a compensation structure 15 on one or both sides of the slot 111, the sheet resistance on the low-level power line 1061 can be kept as consistent as possible with the structure without the slot 111, while ensuring a narrow bezel on the display substrate. When the slot 111 is provided on the low-level power line 1061, the sheet resistance on the low-level power line 1061 will increase without the compensation structure 15. If multiple slots are provided on the power line 106 (for an array antenna), the signal provided by the low-level power line 1061 to the pixel P in the display substrate will be significantly interfered with. Providing the compensation structure 15 can minimize the interference of the slot 111 on the voltage signal provided by the low-level power line 1061. If there are few slots on the low-level power line 1061, the signal provided by the low-level power line 1061 to the pixel P in the display substrate will not be significantly interfered with, and the compensation structure 15 can be omitted.

[0241] In the embodiments disclosed herein, such as Figure 13 and Figure 14 As shown, the low-level power line 1061 can be set around the display area AA.

[0242] This disclosure also provides a display device, including the display substrate described in any of the foregoing embodiments.

[0243] In an exemplary embodiment, the display device may be any product or component having the display substrate of any of the above embodiments, such as a mobile phone, tablet computer, television, monitor, laptop computer, digital photo frame, navigator, wearable device (such as wearable watch, bracelet, etc.), PDA (Personal Digital Assistant).

[0244] This disclosure provides an antenna, a display substrate, and a display device. The antenna includes a first conductive layer, a dielectric layer, and a second conductive layer stacked together. A slot is formed in the first conductive layer, and a comb-shaped conductive structure is formed in the second conductive layer. Each comb-shaped conductive structure includes a first conductive element and a plurality of second conductive elements. The first conductive element forms the back of the comb, and the plurality of second conductive elements form the teeth of the comb. By forming a slot in the first conductive layer, and ensuring that the orthographic projection of the second end of at least a portion of the second conductive elements in the comb-shaped conductive structure on the second conductive layer is within the range of the orthographic projection of the slot in the dielectric layer, the radiation efficiency of the antenna is greatly improved.
