[0034] The following will be combined with the accompanying drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. It should be understood that the specific embodiments described herein are only used to explain the related applications and are not intended to limit the applications. It should also be noted that for ease of description, only the portions relevant to the related applications are shown in the drawings.

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this application pertains. The terms used herein are for the purpose of describing the embodiments of this application only and are not intended to limit this application.

[0036] In the following description, reference is made to “some embodiments”, which describes a subset of all possible embodiments, but it will be understood that “some embodiments” may be the same subset or different subsets of all possible embodiments and may be combined with each other without conflict.

[0037] It should be pointed out that the terms "first\second\third" involved in the embodiments of the present application are only used to distinguish similar objects and do not represent a specific order for the objects. It can be understood that "first\second\third" can be interchanged with a specific order or sequence where permitted, so that the embodiments of the present application described here can be implemented in an order other than that illustrated or described here.

[0038] It should be understood that in order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, each embodiment of the present application will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will understand that in each embodiment of the present application, many technical details are provided to help readers better understand the present application. However, even without these technical details and various changes and modifications based on the following embodiments, the technical solutions claimed in the present application can be implemented.

[0039] The embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0040] In one embodiment of the present application, see Figure 1 , which shows a schematic structural diagram of an antenna provided in an embodiment of the present application. Figure 1 As shown, the antenna may include an antenna body 101 and a metal frame 102;

[0041] The metal frame 102 is arranged around the display panel 103, and the display panel 103 includes multiple semiconductor layers. The antenna body 101 is arranged on at least one of the multiple semiconductor layers of the display panel 103, and at least part of the antenna body 101 is connected to the metal frame 102.

[0042] It should be noted that the antenna provided in the embodiments of the present application can be applied to electronic devices. Electronic devices may include computers, smartphones, tablet computers, laptop computers, PDAs, navigation devices, and the like. Furthermore, the antenna is particularly suitable for all-metal laptop computers. Because the outer shell of an all-metal laptop is a metal shell, the metal shell includes a metal frame 102. Therefore, for an all-metal laptop computer, the antenna can be integrated into the all-metal laptop computer without requiring additional complex processes while meeting its industrial design requirements.

[0043] It should also be noted that the metal frame 102 can be a metal frame of the electronic device itself to which the antenna is applied. Taking an all-metal laptop as an example, the display panel is connected to the metal shell, wherein the surrounding parts of the metal shell connected to the side of the display panel 103 are the metal frame 102, that is, the metal frame 102 is located around the display panel 103, and the plane part of the metal shell parallel to the display panel 103 is the A side of the all-metal laptop, and the A side is the top cover part, that is, the side at the top after the laptop is closed.

[0044] For some electronic devices that do not have a full metal body, if the electronic device itself does not have a metal frame, a metal frame 102 can be formed around the display panel 103 of the electronic device through a certain processing process. The specific type of electronic device is not specifically limited in this embodiment of the application. In the following description, the structure and function of the antenna are specifically described using an all-metal laptop as an example.

[0045] See also Figure 2 , which shows the overall structure of an antenna provided in an embodiment of the present application Figure 1 ,in, Figure 1 For the general Figure 2 The specific structural diagram after the dotted line part is enlarged. Figure 2 As shown, the metal frame 102 is complete, and the metal frame 102 is located around the display panel 103, and the metal frame 102 is arranged around the display panel 103. The display panel 103 can be a display screen of an electronic device, including multiple semiconductor layers, and the antenna 101 is arranged on at least one layer of the multiple semiconductor layers.

[0046] exist Figure 2 In the figure, the metal frame 102 and the display panel 103 are both square, but in practice, other shapes may exist. Regardless of the shape, the antenna can be formed in the manner of the embodiment of the present application.

[0047] It should also be noted that in the embodiments of the present application, the number of antennas can be one or more. For any antenna, the antenna body 101 can be disposed on a suitable semiconductor layer of the display panel 103. Alternatively, different portions of the antenna body 101 of a single antenna can be disposed on different semiconductor layers to achieve better radiation effects. For multiple antennas, the antenna bodies 101 of the multiple antennas can also be disposed on different semiconductor layers to radiate signals of different frequency bands.

[0048] In some embodiments, as Figure 3 or Figure 4 As shown, the antenna may further include a feed point 104; wherein,

[0049] Antenna body 101, used to generate a radiation field;

[0050] The feeding point 104 is used to transmit radio frequency signals corresponding to the target frequency band.

[0051] It should be noted that if Figure 3 or Figure 4 As shown, the antenna body 101 is used to generate a radiation field to transmit and receive signals corresponding to the target frequency band, such as radio frequency signals. The feed point 104 is used to transmit the radio frequency signal corresponding to the target frequency band. For example, the radio frequency signal generated by the circuit in the electronic device is received through the feed point 104, and the radio frequency signal is transmitted to the antenna body 101, so that the antenna body 101 sends the radio frequency signal outward; or, after the antenna body 101 receives the radio frequency signal transmitted externally, the radio frequency signal is transmitted to the circuit in the electronic device for processing through the feed point 104. In this way, based on the antenna body 101 and the feed point 104, the sending and receiving of the radio frequency signal corresponding to the target frequency band is realized. Among them, the target frequency band represents the frequency band in which the antenna works.

[0052] It should also be noted that in the embodiment of the present application, the antenna body 101 and the metal frame 102 together form a complete antenna; wherein, the antenna body 101 is used to radiate signals, and a portion of the antenna body 101 is connected to the metal frame 102, with the metal frame 102 serving as a reference, that is, the metal frame 102 serves as the ground terminal of the antenna, thereby realizing the antenna's radiation function. It can be seen that the design of this antenna in the embodiment of the present application allows the metal frame of the all-metal laptop to directly function as part of the antenna, eliminating the need for additional work such as grooving the metal shell. This, while meeting the antenna's radiation performance, is more conducive to the industrial design of the all-metal laptop.

[0053] Furthermore, in one possible implementation, see Figure 3 , which shows a schematic diagram of the formation position of an antenna provided in an embodiment of the present application Figure 1 .like Figure 3 As shown, the multiple semiconductor layers may include: a lower polarizing glass substrate layer 1031, a thin film transistor substrate layer 1032, a color filter substrate layer 1033 and an upper polarizing glass substrate layer 1034; wherein,

[0054] The antenna body 101 is disposed on the thin film transistor substrate layer 1032 .

[0055] It should be noted that Figure 3 yes Figure 1 The cross-sectional view in the AA' direction is as follows: Figure 3 As shown, the display panel 103 includes multiple semiconductor layers, from bottom to top, including: a bottom polarizing glass substrate layer 1031 (Bottom Polarizing Glass Substrate, Bottom Pol), a thin film transistor substrate layer 1032 (Thin Film Transistor Glass Substrate, TFT), a color filter substrate layer 1033 (Color Filter Glass Substrate, CF) and an upper polarizing glass substrate layer 1034 (Top Polarizing Glass Substrate, Top Pol), Figure 3 The bottom is the A surface 102A of the all-metal notebook computer. The A surface 102A and the metal frame 102 can be as shown in FIG. Figure 3 The antenna body 101 can be disposed above the thin film transistor substrate layer 1032 .

[0056] In another possible implementation, see Figure 4 , which shows a schematic diagram of the formation position of an antenna provided in an embodiment of the present application Figure 2 .like Figure 4 As shown, the multiple semiconductor layers include: a lower polarized glass substrate layer 1031, a thin film transistor substrate layer 1032, a color filter substrate layer 1033, an upper polarized glass substrate layer 1034 and a touch substrate layer 1035; wherein,

[0057] The antenna body 101 is disposed in the non-touch area of the touch substrate layer 1035 .

[0058] It should be noted that Figure 4 for Figure 1 Another cross-sectional view in the AA' direction. For a display panel 103 with a touch function, the display panel 103 may further include a touch substrate layer 1035 (Cover Glass), such as Figure 4As shown, the display panel 103 includes multiple semiconductor layers, which may include, from bottom to top: a lower polarizing glass substrate layer 1031, a thin film transistor substrate layer 1032, a color filter substrate layer 1033, an upper polarizing glass substrate layer 1034 and a touch substrate layer 1035. Figure 4 The bottom is the A surface 102A of the all-metal notebook computer. The A surface 102A and the metal frame 102 can be as shown in FIG. Figure 4 The antenna body 101 can be separated as shown in FIG, or can be integrated. The antenna body 101 can be disposed in a non-touch area below the touch substrate layer 1035, such as an ink area. In this way, while the antenna body 101 is integrated into the display panel 103, it will not affect the normal touch function of the display panel 103, thereby avoiding any impact on the normal use of the electronic device.

[0059] Furthermore, when forming the antenna, in some embodiments, the antenna body 101 is processed by metal deposition and etching to obtain an antenna pattern, and the metal material of the antenna pattern includes at least one of the following: copper and aluminum.

[0060] It should be noted that since the embodiment of the present application sets the antenna body 101 on the semiconductor layer of the display panel 103, it is only necessary to perform metal deposition and etching (such as photolithography) and other processes on the semiconductor layer to form the antenna pattern of the antenna on the semiconductor layer, without the need for additional complex processing.

[0061] Specifically, metal can first be deposited on the target semiconductor layer to form the original antenna body. A mask layer with a certain pattern is then formed above the original antenna body. The portion of the original antenna body exposed by the mask layer is removed by etching or other methods, and the remaining antenna body forms the antenna pattern. The target semiconductor layer represents the semiconductor layer on which the antenna pattern is to be formed. The antenna pattern can be designed based on the desired radiation frequency band, process level, etc., and this embodiment of the application does not specifically limit this.

[0062] In addition, when forming the antenna pattern, a mask layer with a certain pattern may be first formed on the surface of the target semiconductor layer, and then a metal material may be deposited on the surface of the target semiconductor layer exposed by the pattern of the mask layer to form the antenna pattern.

[0063] Since the thickness of the deposited metal material is much smaller than the thickness of the semiconductor layer, when the semiconductor layers are stacked to form the display panel 103 , the normal formation and use of the display panel 103 will not be affected.

[0064] Alternatively, when forming an antenna pattern, an embodiment of the present application may also first form a mask layer having a certain pattern on the surface of the target semiconductor layer, then etch the target semiconductor layer exposed by the pattern of the mask layer to form a groove, and then deposit metal material in the groove to obtain the antenna pattern.

[0065] The metal material of the antenna pattern may include copper, aluminum, or other materials that can be used to manufacture antennas, and is not specifically limited thereto.

[0066] In this way, the antenna body can be prepared in the semiconductor layer of the display panel 103 during the stage of preparing the display panel 103, thereby eliminating the need to purchase an additional antenna, and the process is simple and easy to implement.

[0067] Furthermore, in some embodiments, Figure 1 As shown, the first portion of the antenna body 101 is connected to the metal frame 102 via a metal spring 105;

[0068] The second portion of the antenna body 101 is in direct contact with the metal frame;

[0069] The area of the contact region between the first portion and the metal frame 102 is smaller than the area of the contact region between the second portion and the metal frame 102 .

[0070] It should be noted that if Figure 1 As shown, the antenna body 101 can be divided into a first part and a second part based on the connection method with the metal frame 102. The first part is represented in the antenna body 101 and is connected to the metal frame 102 via a metal spring 105. The second part is represented in the antenna body 101 and is connected to the metal frame 102 by direct contact.

[0071] For the first part, Figure 1 As shown, the first part may include an L-shaped radiation arm 1011A and an irregular radiation arm 1011B, wherein the radiation arm 1011A and the radiation arm 1011B are both connected to the metal frame 102 through the metal spring 105, and the area of the contact area between the radiation arm 1011A and the radiation arm 1011B and the metal frame 102 is relatively small; the second part may include an L-shaped radiation arm 1012A and a straight-line radiation arm 1012B, wherein the radiation arm 1012A and the radiation arm 1012B are both directly connected to the metal frame 102, and the area of the contact area between the radiation arm 1012A and the radiation arm 1012B and the metal frame 102 is relatively large.

[0072] That is, in this antenna, the area of the contact region between the first portion of the antenna body 101 and the metal frame 102 is smaller than the area of the contact region between the second portion of the antenna body and the metal frame 102. Figure 1 As shown, for the radiating arms 1011A and 1011B included in the first portion, the areas in contact with the metal frame 102 are the smaller end portions. Since the contact areas with the metal frame 102 are small, the first portion and the metal frame 102 are connected via the metal spring 105, thereby enabling good contact between the first portion and the metal frame 102. For the radiating arms 1012A and 1012B included in the second portion, the areas in contact with the metal frame 102 are typically the larger side portions. Since the contact areas with the metal frame 102 are large, good contact can be achieved through direct contact.

[0073] Furthermore, in some embodiments, Figure 1 As shown, the antenna body 101 may include at least a first radiation arm 1011A and a second radiation arm 1012B; wherein,

[0074] The first radiation arm 1011A is connected to the metal frame 102 via a metal spring 105;

[0075] The second radiation arm 1012B is directly connected to the metal frame 102 .

[0076] It should be noted that if Figure 1 As shown, in this antenna, the antenna body 101 may include at least two radiating arms, which belong to the aforementioned first and second parts, respectively. For example, the first radiating arm 1011A is the L-shaped radiating arm 1011A in the aforementioned first part, and the first radiating arm 1011A is connected to the metal frame 102 via a metal spring 105; the second radiating arm 1012B is the straight-line radiating arm 1012B in the aforementioned second part, and the second radiating arm 1012B is directly connected to the metal frame 102.

[0077] The first radiating arm 1011A, the metal spring 105, the second radiating arm 1012B, and the metal frame 102 can also form a parasitic wire, thereby expanding the operating frequency band of the antenna. The specific shape of each radiating arm is not specifically limited in this embodiment of the application. For example, the radiating arm can also be F-shaped.

[0078] In some embodiments, the antenna body 101 is disposed in a non-display area of the display panel 103 , or the antenna body 101 is disposed in an edge area of the display panel 103 .

[0079] It should be noted that, in the embodiment of the present application, the antenna body 101 is disposed in a non-display area or edge area of the display panel 103. For example, Figure 3 or Figure 4The antenna body 101 is within a 2 mm area of the edge of the display panel 103. In this way, the antenna body 101 will not enter the display area of the display panel 103, thereby avoiding affecting the display effect of the display panel 103.

[0080] In some embodiments, see Figure 5 , which shows the overall structure of an antenna provided in an embodiment of the present application Figure 2 .like Figure 5 As shown, the metal frame 102 is divided into at least one sub-metal frame 1021 by the non-metal material 106, and the number of the antenna body 101 is at least one; wherein,

[0081] Each sub-metal frame 1021 is connected to an antenna body 101 , so that the antenna operates in different frequency bands.

[0082] It should be noted that if Figure 5 As shown, the embodiment of the present application can also divide the metal frame 102 into at least one sub-metal frame 1021, such as breaking the metal frame 102 and connecting it with non-metal material 106 at the break through an injection molding process, thereby obtaining multiple sub-metal frames 1201. The multiple sub-metal frames 1201 are connected by non-metal materials and are directly non-contacting with each other, thereby forming multiple grounding terminals.

[0083] Accordingly, multiple antenna bodies 101 can be provided, and each sub-metal frame 1021 is connected to an antenna body 101, thus forming multiple antennas, so that the multiple antennas can operate in different frequency bands. The antenna body 101 can be provided on any side of the display panel 103, such as the top, bottom, left, or right. This embodiment of the application does not specifically limit this. For example, Figure 5 In the embodiment, the antenna body 101 is placed on the upper side and left and right sides of the laptop. In practice, the placement of the antenna body 101 can be combined with the specific industrial design. Typically, the antenna body 101 can be placed in a location with fewer lines in the laptop, such as the left and right sides of the display panel.

[0084] Among them, multiple antennas may include Wireless Fidelity (WiFi) antennas, Long Term Evolution (LTE) antennas, fifth generation mobile communication technology (5G) antennas, and millimeter wave antennas, etc. The embodiments of the present application do not specifically limit this, and different frequency bands correspond to antennas.

[0085] In addition, the embodiment of the present application can also form an antenna in the display panel 103 based on existing solutions (such as placing an antenna at the hinge, grooving the metal shell, etc.), thereby increasing the number of antennas and enabling the all-metal notebook to transmit and receive signals in multiple different frequency bands.

[0086] In short, the antenna provided in the embodiment of the present application can prepare the antenna pattern on the semiconductor layer of the display panel (such as a liquid crystal display panel) and combine it with the metal frame part, thereby achieving better performance radiation of the antenna. Figure 1 For example, the metal frame 102 can be combined with multiple metal springs 105, and the metal springs 105 are respectively connected to the antenna body 101 on the side of the display panel 103. The metal circuit formed by the metal frame 102 and the antenna body 101 on the side of the display panel 103 together form a complete antenna and radiate energy together.

[0087] The second part of the antenna body 101 can also be directly connected to the metal frame 102. At the same time, the second part of the antenna body 101 is connected to the metal frame 102 through the metal spring 105. In this way, the first radiation arm 1011A in the first part and the second radiation arm 1012B in the second part are not directly connected, but both are grounded to the metal frame 102. In this way, the metal circuit composed of the antenna body 101 can also form a parasitic antenna to expand the antenna working frequency band.

[0088] In addition, part of the metal frame 102 may be broken and connected using a non-metallic material 106 through an injection molding process, thereby changing the current distribution of the antenna on the metal frame 102 and achieving better radiation matching.

[0089] by Figure 3 and Figure 4 For example, for a display panel 103 that does not include a touch function, when the antenna pattern is prepared in the semiconductor layer of the display panel 103, the antenna pattern can be formed in the edge area of the display panel 103 in the semiconductor process production line of the display panel 103 through metal deposition, photolithography, etching and other process steps, thereby completing the preparation of the antenna radiator (i.e., the antenna body 101); the metal material can be a good conductor such as copper, aluminum, etc., and the metal frame 102 of the laptop computer serves as the antenna grounding terminal to achieve the radiation function of the antenna. For a display panel 103 that includes a touch function, when the antenna pattern is prepared in the semiconductor layer, the antenna pattern can be formed in the ink area of the edge area of the display panel 103 in the semiconductor process production line of the display panel 103 through metal deposition, photolithography, etching and other process steps, thereby completing the preparation of the antenna radiator; the metal material can be a good conductor such as copper, aluminum, etc., and the metal frame 102 of the laptop computer serves as the antenna grounding terminal to achieve the radiation function of the antenna.

[0090] Among them, the radiation principle of the antenna can be based on the radiation structure of the monopole antenna. By designing the antenna pattern, its width is smaller than the width of the non-display area of the display panel 103 (for example, 2 mm), so that the antenna radiator part will not enter the display area, avoiding affecting the display effect of the display panel 103.

[0091] like Figure 3 and Figure 4 As shown, the antenna stack mainly includes a metal backplane (A side) 102A, a lower polarized glass substrate layer 1031, a thin film transistor substrate layer 1032, a color filter substrate layer 1033, and an upper polarized glass substrate layer 1034. For a display panel 103 with a touch function, it may also include a touch substrate layer 1035. The antenna pattern can be prepared on the upper surface of the thin film transistor substrate layer 1032 or the lower surface of the touch substrate layer 1035.

[0092] For further information, see Figure 6 , which shows a schematic diagram of the full-wave simulation results of an antenna provided in an embodiment of the present application. Figure 6 (a) is a diagram showing the relationship between signal frequency and signal strength. Figure 6 (b) is a diagram showing the relationship between signal frequency and radiated power / incident power.

[0093] in, Figure 6 (a) in the figure is a schematic diagram of the relationship between signal frequency and signal strength when the antenna scattering parameter (S parameter) is dB(S(1,1)), where the horizontal axis is the signal frequency in gigahertz (GHz) and the vertical axis is the signal strength in decibels (dB). Figure 6 In (b), the horizontal axis is the signal frequency in GHz, and the vertical axis is the ratio of radiated power to incident power (radiated power / incident power). The closer the ratio corresponding to a certain signal frequency is to 1, the better the radiation performance of the antenna at that signal frequency.

[0094] according to Figure 6 The full-wave simulation results of the antenna are shown, and the antenna efficiency and port performance of the antenna can be seen. Figure 6 As shown, the antenna has good radiation characteristics in the frequency bands of 2.4GHz to 2.5GHz and 5.15GHz to 5.85GHz.

[0095] An embodiment of the present application provides an antenna comprising an antenna body and a metal frame. The metal frame is disposed around a display panel, the display panel comprising multiple semiconductor layers, the antenna body is disposed on at least one of the multiple semiconductor layers of the display panel, and at least a portion of the antenna body is connected to the metal frame. Thus, the antenna body is disposed on at least one semiconductor layer of the display panel, and a portion of the antenna body is connected to the metal frame to form the antenna as a whole. Thus, when the antenna is disposed in an electronic device, the antenna body can be prepared during the process of forming the display panel. Furthermore, the metal frame, as part of the antenna, avoids the additional process of grooving the metal shell of the electronic device and the complex process of additionally disposing the antenna at the hinge. It also eliminates the need for additional space for the antenna. Furthermore, the antenna can fully utilize its radiation performance without affecting its radiation effect.

[0096] Compared with existing solutions, the antenna provided in the embodiments of the present application has at least the following advantages: when forming the antenna, the existing screen preparation process can be directly used to prepare the antenna radiation pattern (i.e., the antenna pattern) during the preparation of the display panel, without the need to purchase additional antennas; since the antenna body can be directly formed on the semiconductor layer of the display panel and together with the metal frame form a complete antenna, there is no need to provide additional placement space for the antenna, and the existing space is fully utilized; full-wave simulation results show that the antenna has better radiation performance; in addition, multiple antennas can be formed by forming multiple antennas on different semiconductor layers, dividing the metal frame into multiple sections, or combining with existing solutions, so that electronic devices can integrate more antennas and realize the reception and transmission of multi-band signals.

[0097] In another embodiment of the present application, see Figure 7 , which shows a schematic diagram of the structure of an electronic device 70 provided in an embodiment of the present application. Figure 7 As shown, the electronic device includes the antenna described in any one of the aforementioned embodiments.

[0098] For the electronic device 70, since it includes the antenna described in any of the aforementioned embodiments, the antenna body of the antenna is arranged on at least one semiconductor layer of the display panel, and part of the antenna body is connected to the metal frame to form the antenna as a whole. Therefore, when the electronic device is provided with the antenna, the preparation of the antenna body can be completed in the process of forming the display panel, and the metal frame is used as part of the antenna, which avoids the additional process of grooving the metal shell of the electronic device and the complicated process of additionally setting up the antenna at the rotating shaft. There is no need to set up additional placement space for the antenna, which can give full play to the radiation performance of the antenna without affecting the radiation effect of the antenna, so that the antenna has better radiation performance. In addition, multiple antennas can be set in the electronic device to realize the reception and transmission of multi-band signals.
