DETAILED DESCRIPTION

The implementations of the present disclosure will be described in detail below with reference to the drawings. Implementations may be implemented in multiple different forms. Those of ordinary skills in the art may easily understand such a fact that implementations and contents may be transformed into various forms without departing from the purpose and scope of the present disclosure. Therefore, the present disclosure should not be explained as being limited to contents described in following implementation modes only. The implementations in the present disclosure and features in the implementations may be combined randomly with each other without conflict. In order to keep following description of the implementations of the present disclosure clear and concise, detailed descriptions about part of known functions and known components are omitted in the present disclosure. The drawings of the implementations of the present disclosure only involve structures involved in the implementations of the present disclosure, and other structures may refer to usual designs.

Scales of the drawings in the present disclosure may be used as a reference in the actual process, but are not limited thereto. For example, a thickness and a pitch of each film layer, and a width and a pitch of each signal line may be adjusted according to an actual situation. The drawings described in the present disclosure are only schematic diagrams of structures, and one mode of the present disclosure is not limited to shapes or numerical values or the like shown in the drawings.

Ordinal numerals such as “first”, “second”, and “third” in the specification are set to avoid confusion of constituent elements, but not to set a limit in quantity.

In the specification, for convenience, wordings indicating orientation or positional relationships, such as “middle”, “upper”, “lower”, “front”, “back”, “vertical”, “horizontal”, “top”, “bottom”, “inside”, and “outside”, are used for illustrating positional relationships between constituent elements with reference to the drawings, and are merely for facilitating the description of the specification and simplifying the description, rather than indicating or implying that a referred apparatus or element must have a particular orientation and be constructed and operated in the particular orientation. Therefore, they cannot be understood as limitations on the present disclosure. The positional relationships between the constituent elements may be changed as appropriate according to a direction according to which each constituent element is described. Therefore, appropriate replacements may be made according to situations without being limited to the wordings described in the specification.

In the specification, unless otherwise specified and defined explicitly, terms “mount”, “mutually connect”, and “connect” should be understood in a broad sense. For example, a connection may be a fixed connection, or a detachable connection, or an integrated connection. It may be a mechanical connection or an electrical connection. It may be a direct mutual connection, or an indirect connection through middleware, or internal communication between two components. Those of ordinary skill in the art may understand specific meanings of these terms in the present disclosure according to specific situations.

In the specification, “electrical connection” includes a case that constituent elements are connected together through an element with a certain electrical effect. The “element with the certain electrical effect” is not particularly limited as long as electrical signals may be sent and received between the connected constituent elements. Examples of the “element having some electrical function” not only include an electrode and a wiring, but also a switch element such as a transistor, a resistor, an inductor, a capacitor, another element having one or more functions, and the like.

In the specification, “parallel” refers to a state in which an angle formed by two straight lines is −10° or more and 10° or less, and thus may include a state in which the angle is −5° or more and 5° or less. In addition, “perpendicular” refers to a state in which an angle formed by two straight lines is above 80 degrees and below 100 degrees, and thus may include a state in which the angle is above 85 degrees and below 95 degrees.

In the specification, a “film” and a “layer” are interchangeable. For example, a “conductive layer” may be replaced with a “conductive film” sometimes. Similarly, an “insulating film” may be replaced with an “insulation layer” sometimes.

Triangle, rectangle, trapezoid, pentagon and hexagon in this specification are not strictly defined, and they may be approximate triangle, rectangle, trapezoid, pentagon or hexagon, etc. There may be some small deformation caused by tolerance, and there may be guide angle, arc edge and deformation, etc.

In the present disclosure, “about” refers to that a boundary is defined not so strictly and numerical values within process and measurement error ranges are allowed.

In the present disclosure, a “thickness” is a dimension of a film layer in a direction perpendicular to a substrate.

The “transmittance” in the present disclosure refers to an ability of light to pass through a medium, and is a percentage of the luminous flux passing through a transparent or translucent body to its incident luminous flux.

In mobile terminals such as mobile phones, notebook computers and automobile glass, as well as wireless applications such as microsatellites, intelligent buildings, intelligent windows, smart wearable devices and on-board communication devices, the various microwave communication devices that are miniaturized and thin-filmed, such as transmission lines, waveguides and antennas, have become a development trend. The thin-filmed traditional large-size microwave device facilitates the conformal structure design and reduces the weight and cost of communication systems.

Especially in recent years, mobile terminals (such as mobile phones) are developing towards ultra-thin, full-screen, and compatible with a series of communication functions, such as the fifth generation mobile communication technology (5G)/fourth generation mobile communication technology (4G)/third generation mobile communication technology (3G)/second generation mobile communication technology (2G), Wireless Fidelity (WIFI), such as WIFI), Near Field Communication (NFC), Bluetooth, Global Positioning System (GPS), China BeiDou Navigation Satellite System (BDS), wireless charging and the like, therefore, the design space reserved for antenna is extremely limited. Moreover, the existing antenna structure of mobile terminals cannot meet the requirements of simultaneously covering multiple frequency bands used for 5G millimeter waves. In addition, the propagation loss of 5G millimeter wave is large. In order to ensure the antenna gain, it is necessary to arrange the antenna, which requires more space to arrange the antenna. These contradictions objectively promote the demand of on-screen antenna. By designing on-screen antenna with good concealment performance, the above-mentioned shortage of design space can be alleviated. At present, transparent oxide conductive materials, such as Indium Tin Oxide (ITO), or multi-layer film materials of metal and conductive oxide, or metal mesh films, are commonly used to achieve transparent antenna design.

In related technologies, the on-screen antenna of the mobile terminal is mainly constructed on the flexible film, and then the flexible film is attached to the screen of the mobile terminal. Since this film attachment process cannot achieve accurate alignment in the semiconductor process, there is an obvious phenomenon that the antenna shields various pixels in the screen, which is easy to produce shielded dark lines and Moire Fringes. In addition, since the metal wires constituting the antenna in the antenna region will block a portion of the incident light, so that the transmittances of the antenna region and the non-antenna region on the screen are not consistent. In order to make the transmittance of the non-antenna region consistent with that of the antenna region as much as possible and passivate the visual effect of inconsistent transmittance, it is usually necessary to construct a grid pattern structure similar to that of the antenna region in the non-antenna region of the screen, so that the transmittance of the whole screen is reduced by 5% to 20%. If a method in which a touch panel (TP) is integrated on a screen encapsulation layer (E. G. OLED encapsulation layer) is directly adopted, although precise alignment in semiconductor technology can be adopted, the radiation efficiency is only about 2.8% according to the radiation theory of microstrip antenna patch due to a fact that the encapsulation layer is only 10 microns away from the metal cathode in the screen. Since the radiation efficiency is too low, it is basically infeasible to directly use semiconductor lithography alignment technology to manufacture antennas.

As shown inFIG.1a,FIG.1bandFIG.1d, the antenna may include a first conductive layer11, a dielectric layer12, a second conductive layer13which are stacked; wherein,the first conductive layer11is provided with at least one slot111;the second conductive layer13may include at least one conductive structure130, the conductive structure130is a comb structure, the conductive structure130may include a first conductive element131constituting a comb back of the comb structure and a plurality of second conductive elements132constituting comb teeth of the comb structure;the at least one conductive structure130is disposed corresponding to at least one slot111, In the at least one conductive structure130, first ends of the plurality of second conductive elements132are connected with the first conductive elements131, and an orthographic projection of the second ends of at least a portion of the second conductive elements132on the dielectric layer11is within an orthographic projection of the slot111on the dielectric layer11.

In the configuration shown inFIG.1athe orthographic projection of the second ends of all the second conductive elements132on the dielectric layer11is within the range of the orthographic projection of the slots111on the dielectric layer11.

In the structure shown inFIG.1d, the orthographic projection of the second ends of a portion of the second conductive element132on the dielectric layer11is within the range of the orthographic projection of the slot111on the dielectric layer11; the orthographic projection of the second ends of the other portion of the second conductive element132on the dielectric layer11does not fall within the range of the orthographic projection of the slot111on the dielectric layer11, i.e. the orthographic projection of the other portion of the second conductive element132on the dielectric layer11is not overlapped with the orthographic projection of the slot111on the dielectric layer11inFIG.1d.

In an exemplary implementation, a dielectric is provided in the slot111and the dielectric in the slot111is formed by the same process as the dielectric layer12. In the implementation of the present disclosure, the formation of the dielectric in the slot111and the dielectric layer12by the same process can simplify the technological process and reduce the cost of manufacturing the antenna. In the implementation of the present disclosure, the dielectric in the slot111is not limited to being the same as the dielectric of the dielectric layer12, and a dielectric different from the dielectric layer12may be employed, for example, the dielectric constant in the slot111may be greater than the dielectric constant of the dielectric layer12. In the implementation of the present disclosure, the dielectric in the slot111is not limited to being formed by the same process as the dielectric layer12and may be manufactured by a different process than the dielectric layer12.

In an exemplary implementation, the width W2of the slot111is 40 microns to 110 microns, the length L4of the slot111in an arrangement direction of the plurality of second conductive elements132(direction Y) is 3.6 mm to 5.0 mm, and in the arrangement direction of the plurality of second conductive elements132, the orthographic projection of the slot111on the dielectric layer12exceeds the orthographic projection of the plurality of second conductive elements132on the dielectric layer12, as shown inFIG.1a-FIG.1d, in the second direction Y, an upper end of the orthographic projection of the slot111on the dielectric layer12is higher than an upper end of the orthographic projection of the plurality of second conductive elements132on the dielectric layer12, and a lower end of the orthographic projection of the slot111on the dielectric layer12is lower than a lower end of the orthographic projection of the plurality of second conductive elements132on the dielectric layer12. In implementations of the present disclosure, the orthographic projection of the slot111on the dielectric layer12exceeds the orthographic projection of the plurality of second conductive elements132on the dielectric layer12, such that the orthographic projection of the second ends of all the first sub-conductive elements1321in the second conductive element132on the dielectric layer12can fall within the range of the slot111, therefore, the electromagnetic wave energy on the first sub-conductive elements1321can be transmitted from the slot111.

In an exemplary implementation, as shown inFIG.1a,FIG.1c,FIG.2a-FIG.2e, the first conductive element131includes a first side A1and a second side A2disposed oppositely, and a third side A3and a fourth side A4disposed oppositely, the second conductive element132being located at the first side A1or the second side A2of the first conductive element131; the plurality of second conductive elements132are arranged along the second direction (direction Y).

In an exemplary implementation, the first conductive element131may adopt a grid structure as illustrated inFIG.1a; or, as shown inFIG.1c, the first conductive element131may be a non-grid structure, for example, the first conductive element131may be a strip structure.

In an exemplary implementation, as shown inFIG.2a-FIG.2e, the second conductive element132includes a first sub-conductive element1321and a second sub-conductive element1322, wherein the first sub-conductive element1321and the second sub-conductive element1322are alternately arranged along the second direction (direction Y);the plurality of first sub-conductive elements1321may be a plurality of first conductive lines a1extending along the first direction (direction X), and the plurality of first conductive lines a1are arranged along the second direction (direction Y);the plurality of second sub-conductive elements1322may be a plurality of second conductive lines a2extending along the first direction (direction X) and arranged along the second direction (direction Y);the length of the first sub-conductive element1321along the first direction (direction X) is greater than the length of the second sub-conductive element1322along the first direction (direction X), an orthographic projection of the second ends of the first sub-conductive elements1321on the dielectric layer12is within the range of the orthographic projection of the slot111on the dielectric layer12, and an orthographic projection of the second ends of the second sub-conductive elements1322on the dielectric layer111is not overlapped with the orthographic projection of the slot111on the dielectric layer12.

In an exemplary implementation, the first conductive line a and the second conductive line a2are of a hollow structure or a solid structure, i.e. the first sub-conductive element1321and the second sub-conductive element1322are of a hollow structure or a solid structure.

In an exemplary implementation, the first sub-conductive element1321and the second sub-conductive element1322are alternately arranged along the second direction (direction Y), and as shown inFIG.2c, one first conductive line a1(i.e., the first sub-conductive element1321) and one second conductive line a2(i.e., the second sub-conductive element1322) are alternately arranged along the second direction (direction Y). In the implementation of the present disclosure, not only one first sub-conductive element1321and one second sub-conductive element1322are alternately disposed along the second direction Y, but also two first sub-conductive elements1321and two second sub-conductive elements1322may be alternately disposed in the second direction (direction Y) as shown inFIG.2e; alternatively, as shown inFIG.2a,FIG.2b, andFIG.2d, in a comb-shaped conductive structure130, one or more first sub-conductive elements1321and one or more second sub-conductive elements1322are alternately disposed along the second direction (direction Y).

In an exemplary implementation, the conductive structure130of the comb structure is an artificial surface plasmon structure. In an exemplary implementation, the artificial surface plasmon structure can be a conductive structure of an ultra-thin comb structure, the first conductive structure11acts as a metallic ground, the conductive structure of ultra-thin comb structure has only one layer of metal film. To tightly bind the electromagnetic energy, in many application scenarios, it is required that the metallic ground (the first conductive structure11) is close to the conductive structure of the comb structure, a large portion of the electromagnetic energy is bound between the metallic ground (the first conductive structure11) and the conductive structure of the comb structure. Similar to microstrip transmission lines, the small distance between the metallic ground and the conductive structure of the comb structure brings a problem of low radiation efficiency of the antenna, implementations of the present disclosure are provided with slots111on the first conductive layer11, such that the orthographic projection of the second ends of at least a portion of the second conductive elements132on the dielectric layer12is within the range of the orthographic projection of the slot111on the dielectric layer11, the electromagnetic wave energy projected on the comb teeth in the slot can be transmitted from the slot without being bound between the metal ground and the conductive structure of the comb structure, thus improving the radiation efficiency of the antenna.

In an exemplary implementation, the second conductive layer13is a transparent conductive layer which can increase transparency, and the application of the antenna in the display device can reduce the occlusion of the screen in the display device and increase the light transmittance.

In an exemplary implementation, each conductive structure of the comb structure includes at least one positive radiation field and at least one negative radiation field, the positive radiation field of the antenna corresponds to a region of the first sub-conductive element1321, the negative radiation field of the antenna corresponds to a region of the second sub-conductive element1322; or, the negative radiation field of the antenna corresponds to the region of the first sub-conductive element1321and the positive radiation field of the antenna corresponds to the region of the second sub-conductive element1322.

In implementations of the present disclosure, since the first sub-conductive element1321and the second sub-conductive element1322are alternately disposed, in the traveling distance of the electromagnetic wave along the conductive structure of comb structure, a positive radiation field and a negative radiation field are periodically formed in the arrangement direction of the second conductive element132. If both the positive radiation field and the negative radiation field are radiated into the free space through the slot, the total radiation field of the far field may be balanced in positive and negative, which reduces the radiation efficiency to a certain extent. Implementations of the present disclosure adopts the alternate arrangement of first sub-conductive elements1321(i.e. long teeth of the comb structure) and second sub-conductive elements1322(i.e. short teeth of the comb structure), and only the projection of the second ends of the first sub-conductive elements1321fall into the slot111, while the projection of the second ends of the second sub-conductive elements1322do not fall into the slot111. When designing the conductive structure of the comb structure in the antenna, two kinds of radiation fields in different directions (including positive radiation field and negative radiation field) are respectively aligned to the region corresponding to the first sub-conductive element1321and the region corresponding to the second sub-conductive element1322. Since the radiation ability of the long and short teeth in the slot are different, coherence enhancement will be formed in the far field instead of coherence subtraction, thus further enhancing the radiation efficiency of the antenna. As shown inFIG.3, C1is a graph showing the relationship between the radiation efficiency and frequency of the antenna in which the slot is provided and the first sub-conductive elements1321and the second sub-conductive elements1321and1322are alternately arranged as shown inFIG.2a-FIG.2e, C2is a graph showing the relationship between the radiation efficiency and frequency of the antenna in which the slot is provided as shown inFIG.1a, and C3is a graph showing the relationship between the radiation efficiency and frequency of the antenna in which the slot is not provided. As can be seen fromFIG.3, in the antenna structure at a frequency of 28 GHz, the radiation efficiency of the antenna provided with the slot (corresponding to graph C2) is increased by about 1.6 times compared with the antenna without slots (corresponding to graph C3); compared with the antenna without the slot (corresponding to graph C3), the radiation efficiency of the antenna provided with the slot and alternated long and short teeth (corresponding to C1) is increased by more than 10 times.

In implementations of the present disclosure, the radiation efficiency of the antenna refers to the ratio of the power delivered to the antenna to the power radiated by the antenna.

In an exemplary implementation, in the case where the conductive structure of the comb structure adopts an artificial surface plasmon structure, the conductive structure130has a size of 1 mm to 2 mm along the arrangement direction of the plurality of second conductive elements132(the direction Y inFIG.2a), and the conductive structure130has a size of 1 mm to 2 mm along an extension direction of the second conductive elements (the direction X inFIG.2a). For example, the size of the antenna may be 1.5 mm*1.5 mm, i.e. the conductive structure130has a size of 1.5 mm along the arrangement direction of the plurality of second conductive elements132(the direction Y inFIG.2a), the conductive structure130has a size of 1.5 mm along the extension direction of the second conductive elements (the direction X inFIG.2a). The antenna of such size has an operation frequency of about 28 GHz and a wavelength of an electromagnetic wave transmitted or received is 10 mm to 12 mm.

In implementations of the present disclosure, in each conductive structure130of the comb structure, the intensity of the electromagnetic wave decays exponentially along a pointing direction of the comb teeth (direction X inFIG.2a) to form an evanescent wave, while the electromagnetic wave may propagates along an arrangement direction of the comb teeth (direction Y inFIG.2a) to form a surface plasma wave (which is a kind of electromagnetic surface wave) in which the electromagnetic wave energy is bound at the tip of the comb teeth. The vector of surface plasmon wave propagating in direction Y is much larger than that in vacuum. By using this property, the size of the antenna and the device carrying the antenna can be compressed, thus realizing the fabrication of a miniaturized antenna and a miniaturized device carrying the antenna. Artificial surface plasmon structure can reduce the size of antenna by means of its own advantages. Although common metal structure can be used as antenna, the size of common metal antenna is relatively large. On the screen of mobile phones or other small electronic devices, it is necessary to minimize the size of antennas, so as to reduce the impact of antennas on display performance and touch layer performance. For example, the size of patch antenna in a frequency of 28 GHz is generally about 3 mm×3 mm, while the size of surface plasmon structure antenna can be compressed to about 1.5 mm×1.5 mm, which greatly reduces the antenna size, thus saving the space of electronic devices provided with antennas and reducing the size of electronic devices provided with antennas as much as possible.

In an exemplary implementation, the dimension W1(the width of the first conductive line a1and the second conductive line a2) of the first sub-conductive element1321(i.e., the first conductive line a1) and the second sub-conductive element1322(i.e., the second conductive line a2) along the second direction Y is 0.01 mm to 0.12 mm; the length L1of the first sub-conductive element1321(i.e. the first conductive line a1) along the first direction X is 0.98 mm to 1.3 mm; the length L2of the second sub-conductive element1322(i.e. the second conductive line a2) along the first direction X is 0.8 mm to 0.95 mm; the distance H1between the centers of two adjacent second conductive elements132is 0.02 mm to 0.4 mm.

In an exemplary implementation, the antenna further includes a feeder line133disposed at the third side A3or the fourth side A4of the first conductive element131; or, the feeder line133is disposed on the comb teeth at the end of the second conductive element132, for example, the feeder line133is disposed on the comb teeth at both ends in the second conductive element132along the second direction Y, as shown inFIG.2d, and the feeder line133may be disposed on the comb teeth at the lower end in the second conductive element132along the second direction Y.

In an exemplary implementation, the width W3of the feeder line133is about 20 microns to 60 microns.

In an exemplary implementation, the sum of the lengths of the conductive structure130and the feeder line133along the arrangement direction of the plurality of second conductive elements132is 2 mm to 3.5 mm, for example, the sum of the lengths of the conductive structure130and the feeder line133along the arrangement direction of the plurality of second conductive elements132is 2.7 mm.

In an exemplary implementation, in the structure shown inFIG.4aandFIG.4b, the arrangement direction of the plurality of second conductive elements132in the first conductive structure1301is parallel to the arrangement direction of the plurality of second conductive elements132in the second conductive structure1302;the first sub-conductive element1321in the first conductive structure1301and the first sub-conductive element1321in the second conductive structure1302are disposed symmetrically with respect to a center line of first conductive structure1301and the second conductive structure1302along the second direction (direction Y), the second sub-conductive element1321in the first conductive structure1301and the second sub-conductive element1322in the second conductive structure1302are disposed symmetrically with respect to a center line of the first conductive structure1301and the second conductive structure1302along the second direction (direction Y).

In an exemplary implementation, the difference between the length of the first sub-connection line1411and the length of the second sub-connection line1412is 0.4 to 0.6 times of the length of the wavelength of the electromagnetic wave. For example, in the structure shown inFIG.4aandFIG.4b, the length of the first sub-connection line1411is smaller than the length of the second sub-connection line1412, and the difference between the length of the first sub-connection line1411and the length of the second sub-connection line may be 0.5 times of the length of the wavelength of the electromagnetic wave transmitted or received by the antenna. In the structure shown inFIG.4candFIG.4d, the length of the first sub-connection line1411may be greater than the length of the second sub-connection line1412, and the difference between the length of the second sub-connection line1412and the length of the first sub-connection line1411may be 0.4 to 0.6 times of the length of the wavelength of the electromagnetic wave transmitted or received by the antenna. For example, the difference between the length of the second sub-connection line1412and the length of the first sub-connection line1411may be 0.5 times of the length of the wavelength of the electromagnetic wave transmitted or received by the antenna.

In an exemplary implementation, as shown inFIG.4bandFIG.4d, a longer one of the first sub-connection line1411and the second sub-connection line1412is of a polygonal line type. In the implementation of the present disclosure, the distance between the first conductive structure1301and the second conductive structure1302can be reduced by setting the longer one of the first sub-connection lines1411and the second sub-connection lines1412as a polygonal line type, thereby reducing the size of the antenna.

In a case where there are not many slots in the low-level power supply line1061, the signal supplied to the pixel P in the display substrate by the low-level power supply line1061is not significantly interfered, and the compensation structure15may not be provided.

In the implementation of the present disclosure as shown inFIG.13andFIG.14, the low-level power supply line1061may be disposed around the display region AA.

An implementation of the present disclosure further provides a display device which includes the display substrate in any one of the aforementioned implementations.

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

An antenna, a display substrate and a display device are provided by the implementation of the present disclosure, the antenna includes a first conductive layer, a dielectric layer, a second conductive layer which are stacked, a slot is provided on the first conductive layer, a conductive structure of a comb structure is disposed on the second conductive layer, each conductive structure of the comb structure includes a first conductive element and a plurality of second conductive elements, the first conductive element constitutes a comb back of the comb structure, the plurality of second conductive elements constitute a comb teeth of the comb structure, the radiation efficiency of the antenna is greatly improved by providing a slot on the first conductive layer, and an orthographic projection of the second end of at least a portion of a second conductive element on the dielectric layer in the conductive structure of the comb structure on the second conductive layer is within the range of an orthographic projection of the slot on the dielectric layer.

The drawings of the implementations of the present disclosure only involve structures involved in the implementations of the present disclosure, and other structures may refer to usual designs.

The implementations of the present disclosure, that is, features in the implementations, may be combined with each other to obtain new implementations if there is no conflict.
