[0034] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0035] In the related art, the antenna unit is generally prepared separately on the dielectric layer, and then the antenna unit is bonded to the display panel through optical glue. This arrangement of the antenna unit not only increases the difficulty of manufacturing the display device, but also increases the thickness of the display device. In addition, the antenna unit is generally arranged at the edge of the display area of ​​the display device. Since the antenna unit itself has a certain grayscale, the antenna unit will affect the luminous brightness at the edge of the display device and affect the display effect of the display panel.

[0036] Based on the defects of the above-mentioned related technologies, the inventor proposes the technical solution in this application. Specifically, this application provides a display panel, including a backlight module, a color film substrate, a liquid crystal layer and an array substrate;

[0037] The color filter substrate and the array substrate are arranged opposite to each other, the array substrate is located on a side of the color filter substrate away from the backlight module, and the liquid crystal layer is located between the color filter substrate and the array substrate;

[0038] The display panel includes a display area and a non-display area arranged around the display area;

[0039] The display panel further includes an antenna unit, which includes a radiation electrode, which is arranged on the array substrate and is located in the non-display area.

[0040] Through the above technical solution, the difficulty of integrating the antenna unit can be reduced, the display panel preparation process can be simplified, and the display panel can be made thinner and lighter. In addition, it can also avoid interference with the antenna unit caused by electrical components and / or signal lines on the display panel and display device. While ensuring the normal radiation receiving performance of the radiation electrode and improving the antenna gain effect, the presence of the radiation electrode will not affect the normal display brightness of the display area, which is beneficial to improving the display effect of the display panel.

[0041] The above is the core idea of ​​the present invention. The technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] Figure 1 A schematic diagram of the structure of a display panel provided by an embodiment of the present invention, Figure 2 for Figure 1 Schematic diagram of the cross-sectional structure along the A-A' direction, Figure 3 for Figure 2 Schematic diagram of the enlarged structure at B, refer to Figure 1 to Figure 3 In the embodiment of the present invention, the display panel includes a backlight module 1, a color filter substrate 2, a liquid crystal layer 3 and an array substrate 4; the color filter substrate 2 and the array substrate 4 are arranged opposite to each other, the array substrate 4 is located on the side of the color filter substrate 2 away from the backlight module 1, and the liquid crystal layer 3 is located between the color filter substrate 2 and the array substrate 4; the display panel includes a display area and a non-display area NA arranged around the display area AA; the display panel also includes an antenna unit 5, the antenna unit 5 includes a radiation electrode 6, the radiation electrode 6 is arranged on the array substrate 4, and the radiation electrode 6 is located in the non-display area NA.

[0043] Specifically, Figure 1 to Figure 3As shown, the display panel includes a color filter substrate 2 and an array substrate 4 that are arranged opposite to each other, and a liquid crystal layer 3 is arranged between the color filter substrate 2 and the array substrate 4. A backlight module 1 is also arranged on the side of the color filter substrate 2 that is away from the array substrate 4, that is, in the present application, the array substrate 4 is arranged on the light-emitting side of the display panel, and the color filter substrate 2 and the backlight module 1 are arranged on the same side away from the light-emitting side. When the display panel is displaying, the backlight module 1 emits light. At the same time, the liquid crystal molecules in the liquid crystal layer 3 rotate under the drive of the array substrate 4, and the light emitted by the backlight module 1 is emitted toward the liquid crystal layer 3 through the color filter substrate 2, and then emits light of different colors through the array substrate 4. It should be noted that in order to clearly show the arrangement of the radiation electrode 6, Figure 1 The film layers in the display area AA are not shown in the top view of the display panel.

[0044] Furthermore, it is worth pointing out that in the present application, the antenna unit 5 is directly arranged on the display panel. Specifically, the radiation electrode 6 in the antenna unit 5 is arranged on the array substrate 4 located on the light-emitting side of the display panel. This arrangement has the following advantages: First, the radiation electrode 6 can be directly made on the array substrate 4, eliminating the process of preparing the radiation electrode 6 on other dielectric layers and then bonding them, which can not only simplify the display panel preparation process, but also the antenna unit 5 will not have a significant impact on the thickness of the display panel. Compared with the means in the above-mentioned related technologies, the thickness of the display panel can be reduced to achieve a thinner display panel. Secondly, it is known to those skilled in the art that a large number of wirings are already arranged on the array substrate 4. The process of setting the radiation electrode 6 on the array substrate 4 has a high degree of realization, and the radiation electrode 6 and the wirings can be prepared in the same process, which further simplifies the display panel preparation process.

[0045] It should be noted that in the present application, the array substrate 4 is located on the side of the color filter substrate 2 away from the backlight module 1 to reduce the number of film layers between the radiation electrode 6 on the array substrate 4 and the outside world, thereby reducing radiation loss and facilitating improving the gain of the antenna unit 5.

[0046] The embodiment of the present invention does not limit the specific film layer of the radiation electrode 6 in the array substrate 4, and those skilled in the art may configure it according to actual needs. Figure 3 The film layer where the radiation electrode 6 is located is only an optional manner, not a limitation on the position.

[0047] In addition, in this embodiment, the radiation electrode 6 is entirely located in the non-display area NA. In this way, whether the radiation electrode 6 is made of a transparent material or a non-transparent material, it will not affect the normal display of the display area AA, which is beneficial to improving the display effect of the panel. At the same time, the radiation electrode 6 is arranged in the non-display area NA, which can also prevent the display panel, the electrical components and / or signal lines on the display device, etc. from affecting the radiation electrode 6 in transmitting and receiving signals, and prevent the antenna unit 5 from being interfered.

[0048] Optionally, in a possible embodiment, the radiation electrode 6 may be made of a metal conductive material, such as copper. Copper has good conductivity. When copper is used as the radiation electrode 6, the impedance of the radiation electrode 6 is small, and the signal loss on the radiation electrode 6 is small, which is beneficial to the gain of the antenna unit. Of course, in other possible embodiments, the radiation electrode 6 may be made of a transparent conductive material, such as ITO. In actual application, those skilled in the art may select the material for preparing the radiation electrode 6 according to actual needs, and the embodiment of the present invention is not limited to this.

[0049] In addition, the embodiment of the present invention does not limit the shape and thickness of the radiation electrode 6, and those skilled in the art can set them according to actual needs. For example, the radiation electrode 6 can be set to a patch structure with a thickness of micrometer level to ensure that the radiation electrode 6 has little effect on the thickness of the display panel.

[0050] Optionally, the embodiment of the present invention does not limit the number of antenna units 5 in the display panel, and those skilled in the art may set them according to actual needs. The number of antenna units 5 shown in the figure is only an example. Figure 1 FIG. 5 exemplarily shows that the antenna unit 5 is located in the non-display area NA above the display panel, but the actual arrangement is not limited thereto.

[0051] In an embodiment of the present invention, the display panel includes a backlight module, a color film substrate, a liquid crystal layer and an array substrate; the color film substrate is arranged opposite to the array substrate, the array substrate is located on the side of the color film substrate away from the backlight module, and the liquid crystal layer is located between the color film substrate and the array substrate; the display panel includes a display area and a non-display area arranged around the display area; the display panel also includes an antenna unit, the antenna unit includes a radiation electrode, the radiation electrode is arranged on the array substrate, and the radiation electrode is located in the non-display area. The above technical solution can reduce the difficulty of integrating the antenna unit, simplify the display panel preparation process, and realize the thinness of the display panel; in addition, it can also avoid the interference of the electrical devices or / and signal lines on the display panel and the display device to the antenna unit. While ensuring the normal radiation receiving performance of the radiation electrode and improving the antenna gain effect, the existence of the radiation electrode will not affect the normal display brightness of the display area, which is conducive to improving the display effect of the display panel.

[0052] Optional, can still refer to Figure 3In a possible embodiment, the antenna unit 5 may further include a grounding conductive layer 7; the grounding conductive layer 7 is located on a side of the radiation electrode 6 close to the color film substrate 2, and along the thickness direction Z of the display panel, the grounding conductive layer 7 covers the radiation electrode 6.

[0053] For details, please refer to Figure 3 , a grounding conductive layer 7 may also be provided in the antenna unit 5, and the grounding conductive layer 7 serves as a grounding layer of the antenna unit 5. In this embodiment, the grounding conductive layer 7 may be provided on the side of the radiation electrode 6 close to the color filter substrate 2, so that the radiation electrode 6 radiates and receives signals in a direction away from the color filter substrate 2. The thickness direction Z of the display panel is also the vertical light emitting direction of the display panel. Along the thickness direction Z of the display panel, the grounding conductive layer 7 may cover the radiation electrode 6 to avoid antenna signal loss, improve antenna gain, and ensure the signal transmission and reception strength of the antenna unit 5.

[0054] The embodiment of the present invention does not limit the specific setting position and material parameters of the grounding conductive layer 7, and those skilled in the art can set them according to actual needs. For example, the grounding conductive layer 7 can be a conductive metal layer (such as copper) or a transparent conductive layer (such as ITO), but is not limited thereto.

[0055] For example, please refer to Figure 2 and Figure 3 In a possible embodiment, the array substrate 4 may include a first substrate 8 and a pixel electrode 9 and a common electrode 10 located between the first substrate 8 and the liquid crystal layer 3; the color film substrate 2 includes a second substrate 11 and a transparent conductive layer 12 located on a side of the second substrate 11 away from the array substrate 4; the ground conductive layer 7 may be arranged on the same layer as the transparent conductive layer 12.

[0056] Specifically, Figure 2 and Figure 3 As shown, the array substrate 4 may include a first substrate 8, a pixel electrode 9 and a common electrode 10. The first substrate 8 may be a glass substrate to have a higher light transmittance and reduce the impact on display brightness, but it is not limited thereto.

[0057] The pixel electrode 9 and the common electrode 10 are both arranged on the array substrate 4, that is, the pixel electrode 9 and the common electrode 10 are both arranged on the same side of the liquid crystal layer 3, for example, the pixel electrode 9 and the common electrode 10 are both arranged on the side of the first substrate 8 facing the liquid crystal layer 3, and a lateral electric field is generated between the pixel electrode 9 and the common electrode 10 to act on the liquid crystal layer 3 to control the deflection of the liquid crystal molecules in the liquid crystal layer 3. At this time, the display panel is an in-plane switching (IPS) display panel. In the IPS display mode, the liquid crystal molecules flip in the horizontal direction (perpendicular to the thickness direction Z of the display panel shown in the figure), and the display panel can present a wider viewing angle. Figure 2FIG. 4 exemplarily shows that the pixel electrode 9 and the common electrode 10 are located in different film layers of the array substrate 4 , but the actual arrangement is not limited thereto, and the pixel electrode 9 and the common electrode 10 may also be arranged in the same layer.

[0058] Furthermore, the color filter substrate 2 may include a second substrate 11 and a transparent conductive layer 12. The second substrate 11 may also be a glass substrate to have a higher light transmittance and reduce the impact on display brightness, but is not limited thereto.

[0059] The transparent conductive layer 12 may be a whole layer of ITO or other transparent conductive film layers. The transparent conductive layer 12 may be formed on the side of the second substrate 11 away from the array substrate 4. The transparent conductive layer 12 may be grounded or connected to other electronic devices that can eliminate static electricity, which can be used to guide or eliminate static electricity inside the display panel, thereby improving the reliability of the display panel.

[0060] The color filter substrate 2 may also be provided with any other film layer structures known to those skilled in the art, such as a color resist 13, a black matrix 26 and a polarizer 14, etc. The present invention does not elaborate on or limit the specific arrangement of the above film layer structures.

[0061] Among them, Figure 3 As shown in the figure, the grounding conductive layer 7 can be arranged in the film layer where the transparent conductive layer 12 is located. In this way, the grounding conductive layer 7 is in the same layer as the transparent conductive layer 12, and the thickness of the display panel will not be increased additionally, thereby ensuring that the display panel is light and thin. In addition, when the transparent conductive layer 12 and the grounding conductive layer 7 are made of the same material, the transparent conductive layer 12 and the grounding conductive layer 7 can be prepared in the same process, which can also simplify the display panel preparation process.

[0062] Optional, continue to refer to Figure 3 In a possible embodiment, the grounding conductive layer 7 and the transparent conductive layer 12 may be the same conductive layer. That is, in this embodiment, the transparent conductive layer 12 may be reused as the grounding conductive layer 7, which is used to eliminate static electricity and also serves as the grounding layer of the antenna unit 5. There is no need to prepare the grounding conductive layer 7 additionally, which further simplifies the process flow. At the same time, the grounding conductive layer 7 and the transparent conductive layer 12 have the same structure and are connected to the same potential, which can simplify the wiring design and make it easy to implement; and when preparing the grounding conductive layer 7 and the transparent conductive layer 12, the patterning process can be reduced and the process time can be shortened.

[0063] Among them, the thickness of the transparent conductive layer 12 can be between several hundred angstroms (A) and several thousand angstroms (A). Within this thickness range, the conductive performance of the transparent conductive layer 12 is better, thereby achieving a better static electricity elimination effect. As a grounded conductive layer 7, it also helps to reduce signal loss and increase the gain of the antenna unit 5. At the same time, the transparent conductive layer 12 will not be too thick to affect the thin and light design of the display panel.

[0064] Figure 4 A partial cross-sectional structural diagram of a display panel provided by an embodiment of the present invention, referring to Figure 4 When the grounding conductive layer 7 and the transparent conductive layer 12 are arranged in the same layer, the grounding conductive layer 7 and the transparent conductive layer 12 can also be arranged separately and insulated from each other, so that the transparent conductive layer 12 can be connected to other components without being grounded.

[0065] Figure 5 A schematic cross-sectional structure diagram of a display panel provided by an embodiment of the present invention, Figure 6 for Figure 5 Schematic diagram of the enlarged structure at C, refer to Figure 5 and Figure 6 In this embodiment, the array substrate 4 may include a first substrate 8 and a pixel electrode 9 located between the first substrate 8 and the liquid crystal layer 3; the color film substrate 2 includes a second substrate 11 and a common electrode 10 located between the second substrate 11 and the liquid crystal layer 3; the ground conductive layer 7 may be arranged on the same layer as the common electrode 10.

[0066] Specifically, Figure 5 and Figure 6 As shown, the array substrate 4 is still provided with the first substrate 8, the color filter substrate 2 is still provided with the second substrate 11, and the pixel electrode 9 is still provided on the side of the first substrate 8 facing the liquid crystal layer 3. Figure 3 The difference from the illustrated embodiment is that in this embodiment, the common electrode 10 is arranged in the color filter substrate 2, and can be specifically arranged on the side of the second substrate 11 facing the liquid crystal layer 3. At this time, the common electrode 10 and the pixel electrode 9 are respectively arranged on both sides of the liquid crystal layer 3, and a vertical electric field is formed between the pixel electrode 9 and the common electrode 10 to act on the liquid crystal layer 3 to control the liquid crystal molecules in the liquid crystal layer 3 to deflect. At this time, the display panel is a twisted nematic (TN) or multi-quadrant vertical alignment (VA) display panel. In the TN or VA display mode, the liquid crystal molecules flip in the vertical direction (the thickness direction Z of the display panel shown in the figure), and the response speed of the TN or VA display panel is faster. In this setting mode, the ground conductive layer 7 can be set in the film layer where the common electrode 10 is located, that is, the ground conductive layer 7 is set in the same layer as the common electrode 10.

[0067] Among them, the grounding conductive layer 7 and the common electrode 10 are arranged in the same layer, which can reduce the arrangement of one film layer, thereby achieving the purpose of reducing production costs and reducing the thickness of the display panel. In addition, the grounding conductive layer 7 and the common electrode 10 can be made of the same material, so that the grounding conductive layer 7 and the common electrode 10 can be prepared in the same process, thereby shortening the process time.

[0068] Also optional, continue to refer to Figure 5 and Figure 6, the grounding conductive layer 7 and the common electrode 10 can be the same film structure. That is, the common electrode 10 is reused as the grounding conductive layer 7, wherein the grounding conductive layer 7 and the transparent conductive layer 12 are set as an integral structure and connected to the same potential, which can simplify the wiring design and make it easy to implement; and when preparing the grounding conductive layer 7 and the common electrode 10, the patterning process can be reduced and the process time can be shortened.

[0069] Figure 7 A partial cross-sectional structural diagram of another display panel provided by an embodiment of the present invention, referring to Figure 7 When the ground conductive layer 7 and the common electrode 10 are provided in the same layer, the ground conductive layer 7 and the common electrode 10 can also be provided separately and insulated from each other. In this way, the potential of the common electrode 10 may not be the ground potential.

[0070] Figure 8 A partial cross-sectional structural diagram of another display panel provided in an embodiment of the present invention is shown in FIG. Figure 8 In a possible embodiment, the array substrate 4 may include a first substrate 8 and a pixel electrode 9 located between the first substrate 8 and the liquid crystal layer 3; the color film substrate 2 includes a second substrate 11 and a common electrode 10 located between the second substrate 11 and the liquid crystal layer 3; and the ground conductive layer 7 is located on a side of the common electrode 10 close to the array substrate 4.

[0071] Specifically, Figure 8 In the embodiment shown, the arrangement of the pixel electrode 9 and the common electrode 10 can be similar to Figure 5 The embodiment shown is the same, the difference between the two is that Figure 8 In the illustrated embodiment, the ground conductive layer 7 is no longer arranged in the same layer as the common electrode 10, but the ground conductive layer 7 can be arranged on the side of the common electrode 10 close to the array substrate 4, that is, along the thickness direction Z of the display panel shown in the figure, the ground conductive layer 7 can be arranged above the common electrode 10. At this time, the ground conductive layer 7 can be directly formed on the surface of the side of the common electrode 10 away from the second substrate 11. Under this arrangement, the distance between the radiation electrode 6 of the antenna unit 5 and the ground conductive layer 7 is smaller, which can reduce signal loss, help improve the antenna radiation efficiency, and enhance the antenna gain. At the same time, the ground conductive layer 7 can be made of a different metal material from the common electrode 10 to obtain better conductivity, thereby helping to reduce signal loss and improve the gain of the antenna unit 5.

[0072] In the above embodiments, the grounding conductive layer 7 is located on the side of the liquid crystal layer 3 close to the color filter substrate 2. In other optional embodiments, the grounding conductive layer 7 can also be arranged on the side of the liquid crystal layer 3 close to the array substrate 4. Fig. 9 A partial cross-sectional structural diagram of another display panel provided by an embodiment of the present invention is shown in FIG. Fig. 9As shown, the ground conductive layer 7 can be disposed on the array substrate 4 .

[0073] Fig. 9 In the illustrated embodiment, the grounding conductive layer 7 may be disposed on a side of the array substrate 4 close to the liquid crystal layer 3. Specifically, along the thickness direction Z of the display panel, the grounding conductive layer 7 may be located between the radiation electrode 6 and the liquid crystal layer 3. In this way, the grounding conductive layer 7 may be prepared by utilizing the existing metal layer in the array substrate 4, or the metal wiring of the array substrate 4 located in the non-display area NA may be directly reused as the grounding conductive layer 7.

[0074] At the same time, the ground conductive layer 7 can be arranged on the array substrate 4, which can make the distance between the radiation electrode 6 of the antenna unit 5 and the ground conductive layer 7 smaller, thereby reducing signal loss, which is beneficial to improving the antenna radiation efficiency and enhancing the antenna gain.

[0075] in, Figure 7 The ground conductive layer 7 is exemplarily shown to be located on the side of the radiation electrode 6 facing the liquid crystal layer, and the actual arrangement is not limited thereto. In addition, it should be noted that, under this arrangement of the ground conductive layer 7, the common electrode 10 can be arranged on both the array substrate 4 and the color filter substrate 2, and the embodiment of the present invention is not limited thereto.

[0076] Fig.10 A partial top view of a display panel provided by an embodiment of the present invention is shown. Fig.11 for Fig.10 Schematic diagram of the cross-section structure along E-E', refer to Fig.10 and Fig.11 Optionally, in a possible embodiment, the antenna unit 5 may further include a ground conductive layer 7, which is located in the non-display area NA; the ground conductive layer 7 and the radiation electrode 6 are arranged in the same layer, and the ground conductive layer 7 and the radiation electrode 6 are insulated.

[0077] Specifically, in this embodiment, the ground conductive layer 7 is entirely located in the non-display area NA to prevent the ground conductive layer 7 from affecting the normal display of the display area AA, which is beneficial to improving the display effect of the panel.

[0078] The grounding conductive layer 7 is provided at the same layer as the radiation electrode 6, which can reduce the provision of one film layer, thereby achieving the purpose of reducing production costs and reducing the thickness of the display panel. In addition, the grounding conductive layer 7 can be made of the same material as the radiation electrode 6, so that the grounding conductive layer 7 and the radiation electrode 6 can be prepared in the same process, thereby shortening the process time.

[0079] At the same time, in order to ensure that the antenna unit 5 can normally transmit and receive signals, the ground conductive layer 7 and the radiation electrode 6 should be insulated from each other.

[0080] Optionally, when the pixel electrode 9 and the common electrode 10 are located on the same side of the array substrate 4, that is, in the IPS display mode, if the ground conductive layer 7 is not provided in the color filter substrate 2, for example, Fig.11 As shown in , when the ground conductive layer 7 and the radiation electrode 6 are arranged in the same layer, the color filter substrate 2 may no longer be provided with a transparent conductive layer 12, but a low-resistance polarizer 15 may be directly arranged on one side of the second substrate 11, and the static electricity inside the display panel is guided out by the low-resistance polarizer 15. In this arrangement, the number of film layers in the color filter substrate 2 is reduced, which is conducive to further reducing the overall thickness of the display panel.

[0081] Optionally, when the common electrode 10 is disposed in the array substrate 4 , the common electrode 10 may be reused as the ground conductive layer 7 , but is not limited thereto.

[0082] The specific arrangement of the ground conductive layer 7 and the radiation electrode 6 in the same film layer is not limited in the embodiment of the present invention, and those skilled in the art can arrange it according to actual needs. Fig.10 and Fig.11 The antenna unit 5 may include at least one repeating unit 24, the repeating unit 24 includes a radiation electrode block 61, a feeding line 62 and a grounding electrode block 70, the feeding line 62 is electrically connected to the radiation electrode block 61, and is used to transmit a radio frequency signal to the radiation electrode block 61. The grounding electrode block 70 includes a first electrode block 71 and a second electrode block 72, and the first electrode block 71 and the second electrode block 72 are respectively located on both sides of the feeding line 62 along a direction perpendicular to the extending direction of the feeding line 62. The radiation electrode block 61 constitutes the radiation electrode 6, and the grounding electrode block 70 constitutes the grounding electrode layer 7. Fig.10 In the description, the antenna unit 5 includes only one repeating unit as an example, but the invention is not limited thereto.

[0083] Optional, can still refer to Fig.10 and Fig.11 In a possible embodiment, the ground conductive layer 7 is located in the non-display area NA; the ground conductive layer 7 is a metal layer.

[0084] by Fig.10 For example, the ground conductive layer 7 may be entirely located in the non-display area NA, so as to avoid the ground conductive layer 7 affecting the normal display of the display area AA, which is beneficial to improving the display effect of the panel.

[0085] At this time, the ground conductive layer 7 can be prepared by using a metal material with good conductivity (such as copper), that is, the ground conductive layer 7 is set as a metal layer. This is conducive to reducing the impedance of the ground conductive layer 7, reducing the insertion loss, and improving the radiation efficiency of the antenna unit 5.

[0086] In other possible embodiments, the grounding conductive layer 7 may also include a first portion located in the non-display area NA and a second portion located in the display area AA, the first portion is made of metal material, and the second portion is made of transparent conductive material, which is not limited in this embodiment of the present invention.

[0087] The embodiment of the present invention does not limit the specific shape of the grounding conductive layer 7 in the above embodiment, and those skilled in the art can set it according to actual needs, and it can be set to the same or different shape as the radiation electrode 6.

[0088] Optional, you can continue to refer to Figure 6 to Figure 8 When the pixel electrode 9 and the common electrode 10 are arranged on different sides of the liquid crystal layer 3, the display panel may further include a conductive gold ball 16 located between the array substrate 4 and the color filter substrate 2, the conductive gold ball 16 is located in the non-display area NA, and the conductive gold ball 16 is respectively connected to the common electrode 10 and the array substrate 4; the vertical projection of the radiation electrode 6 on the color filter substrate 2 is located outside the vertical projection of the conductive gold ball 16 on the color filter substrate 2.

[0089] Specifically, Figure 6 to Figure 8 As shown, a conductive gold ball 16 is provided between the array substrate 4 and the color filter substrate 2, and the conductive gold ball 16 is used to realize the electrical connection between the common electrode 10 and the array substrate 4. Those skilled in the art can understand that the electrical connection between the common electrode 10 and the array substrate 4 mentioned here refers to the electrical connection between the common electrode wiring in the array substrate 4 and the common electrode 10, and then the power supply voltage signal transmitted in the common electrode wiring is transmitted to the common electrode 10.

[0090] Among them, the conductive gold ball 16 is located entirely in the non-display area NA, and the vertical projection of the conductive gold ball 16 on the color filter substrate 2 does not overlap with the vertical projection of the radiation electrode 6 on the color filter substrate 2, thereby preventing the conductive gold ball 16 from electrically connecting the radiation electrode 6 and the ground conductive layer 7, thereby affecting the normal signal reception and transmission of the antenna unit 5.

[0091] Fig.12 A schematic cross-sectional structure diagram of another display panel provided by an embodiment of the present invention, Fig.13 for Fig.12 Schematic diagram of the enlarged structure at D, optional, refer to Fig.12 and Fig.13 In a possible embodiment, the display panel may further include a frame glue 17 located between the array substrate 4 and the color film substrate 2, and the frame glue 17 is arranged around the liquid crystal layer 3; along the thickness direction Z of the display panel, the radiation electrode 6 is located on the side of the frame glue 17 away from the liquid crystal layer 3.

[0092] Specifically, the frame glue 17 is arranged around the liquid crystal layer 3 to play the role of encapsulating liquid crystal molecules, and the frame glue 17 can also play a certain supporting role for the array substrate 4 and the color filter substrate 2. Among them, along the thickness direction Z of the display panel, the radiation electrode 6 can be arranged on the side of the frame glue 17 away from the liquid crystal layer 3. If the liquid crystal layer 3 is defined to be located on the inner side of the frame glue 17, the radiation electrode 6 can be located on the outer side of the frame glue 17. If the ground conductive layer 7 is located on the color filter substrate 2, the medium between the radiation electrode 6 and the ground conductive layer 7 is air, the dielectric constant of air is relatively small, the dielectric loss is correspondingly small, and the gain effect of the antenna unit 5 is better.

[0093] Fig.12 and Fig.13 It is exemplarily shown that the common electrode 10 is arranged on the color filter substrate 2, and the ground conductive layer 7 and the common electrode 10 are in the same layer, but the actual arrangement is not limited thereto. In other embodiments, the common electrode 10 may still be arranged on the color filter substrate 2, but the ground conductive layer 7 and the common electrode 10 are arranged in different layers, or the common electrode 10 is arranged on the array substrate 4, and the ground conductive layer 7 is arranged in the same layer as the transparent conductive layer in the color filter substrate 2, etc. On the basis of ensuring that the radiation electrode 6 is located on the side of the frame glue 17 away from the liquid crystal layer 3 along the thickness direction Z of the display panel, the specific arrangement of the common electrode 10 and the ground conductive layer 7 can be adjusted at will.

[0094] In order to reduce the space of the frame area of ​​the display panel, the conductive gold balls 16 can be arranged inside the frame glue 17 .

[0095] Fig.14 A partial cross-sectional structural diagram of another display panel provided by an embodiment of the present invention is shown in FIG. Fig.14 As shown, the display panel still includes a sealant 17 located between the array substrate 4 and the color filter substrate 2 , and the sealant 17 is arranged around the liquid crystal layer 3 ; along the thickness direction Z of the display panel, the radiation electrode 6 at least partially overlaps with the sealant 17 .

[0096] Specifically, Fig.14 The arrangement of the sealant 17 in the embodiment shown is the same as that in the above embodiment, but the relative position relationship between the sealant 17 and the radiation electrode 6 is different. Fig.14 As shown in the figure, in this embodiment, along the thickness direction Z of the display panel, there is an overlapping area between the radiation electrode 6 and the frame glue 17. Under this arrangement, the radiation electrode 6 and the frame glue 17 occupy a smaller size in the non-display area NA, which is beneficial to reducing the width of the display panel frame and achieving a narrow frame.

[0097] Fig.15 A partial cross-sectional structural diagram of another display panel provided in an embodiment of the present invention can be referred to Fig.15In a possible embodiment, along the thickness direction Z of the display panel, the sealant 17 may cover the radiation electrode 6. That is, along the thickness direction Z of the display panel, the radiation electrode 6 may be completely located in the area covered by the sealant 17. In this way, if the ground conductive layer 7 is provided on the color film substrate 2, the area between the radiation electrode 6 and the ground conductive layer 7 is all the sealant 17, the dielectric constant is consistent, and the signal loss between different areas of the radiation electrode 6 and the ground conductive layer 7 is basically consistent, which is beneficial to improve the gain uniformity of the antenna unit 5.

[0098] Optionally, in a possible embodiment, the radiation electrode 6 may be a light-transmitting electrode.

[0099] Specifically, the radiation electrode 6 can be prepared as a light-transmitting electrode using a transparent material. During the production process of the liquid crystal display panel, the frame glue 17 needs to be cured. Taking the liquid crystal drop-type injection (One Drop Filling, ODF) process as an example, after the liquid crystal display panel is boxed, the frame glue 17 is generally pre-cured with ultraviolet (UV) and then thermally cured. Among them, the UV pre-curing speed is faster, which is conducive to avoiding misalignment between the color filter substrate 2 and the array substrate 4 on both sides of the liquid crystal layer 3.

[0100] exist Fig.14 and Fig.15 In the illustrated embodiment, since part of the radiation electrode 6 overlaps with the frame glue 17, at this time, the radiation electrode 6 is set as a light-transmitting electrode, and the ultraviolet light can pass through the radiation electrode 6 to react with the frame glue 17, thereby achieving normal UV pre-curing of the frame glue 17, ensuring the curing effect of the frame glue 17, and ensuring accurate alignment between the color filter substrate 2 and the array substrate 4 on both sides of the liquid crystal layer 3.

[0101] Optional, Fig.16 A schematic diagram of a top view structure of a radiation electrode provided in an embodiment of the present invention, referring to Fig.16 In other possible embodiments, the material of the radiation electrode 6 may be metal, and the radiation electrode 6 is a grid structure.

[0102] As mentioned in the above embodiment, using a metal conductive material to prepare the radiation electrode 6 is beneficial to improving the gain of the antenna unit 5. When the radiation electrode 6 is a metal electrode, the radiation electrode 6 can be set to Fig.16 As shown in the grid shape, the grid-shaped radiation electrode 6 can also ensure the transmission of ultraviolet light and will not affect the pre-curing effect of the frame glue 17.

[0103] When the radiation electrode 6 is Fig.16 When the grid shape is shown, the ground conductive layer 7 can also be set to Fig.16 A grid is shown, but is not limited to this.

[0104] Optionally, in another possible embodiment, the material of the radiation electrode 6 is metal, and the sealant 17 is pure heat-curing sealant.

[0105] In this embodiment, the radiation electrode 6 is still a metal electrode, but it is worth mentioning that the sealant 17 can be set as a pure heat-curing sealant. That is, there is no need to perform UV pre-curing on the sealant 17, and the sealant 17 can be cured only by heating. At this time, even if the radiation electrode 6 is not light-transmissive, it will not affect the curing effect of the sealant 17. The radiation electrode 6 can directly adopt a patch structure, which is conducive to simplifying the formation process of the radiation electrode 6.

[0106] Among them, optionally, a modified epoxy resin material can be used to make the frame glue 17. This material does not react with liquid crystal molecules, hardly pollutes the liquid crystal, and can effectively suppress the occurrence of poor display problems such as white spots, uneven orientation, and screen burn-in. Of course, in actual application, technicians in this field can also choose other thermosetting materials to prepare the frame glue 17 according to actual needs.

[0107] In addition, Figure 1 to Figure 15 In the display panel shown, the radiation electrode 6 can be prepared into a grid, block or other arbitrary shapes according to actual needs. The shape of the ground conductive layer 7 can also be a grid, block or other arbitrary shapes. In a preferred embodiment, the ground conductive layer 7 is in a block shape, and the patterning process of the ground conductive layer 7 is omitted. It should be noted that when the ground conductive layer 7 and the radiation electrode 6 are arranged in the same pattern, the pattern line width of the ground conductive layer 7 can be set to be greater than or equal to the pattern line width of the radiation electrode 6 to ensure the gain of the antenna unit 5.

[0108] Optional, you can continue to refer to Figure 1 to Figure 15 , the array substrate 4 still includes a first substrate 8 ; the radiation electrode 6 is located on a side of the first substrate 8 close to the color filter substrate 2 , and the radiation electrode 6 is in contact with and connected to the first substrate 8 .

[0109] Specifically, in the embodiment of the present application, the radiation electrode 6 can be directly prepared on the surface of the first substrate 8 facing the liquid crystal layer 3, so that the radiation electrode 6 is in contact with the first substrate 8. The first substrate 8 can generally be set as a glass substrate, so that the radiation electrode 6 is separated from the outside world by only the glass substrate, which can reduce signal loss and is conducive to improving the radiation receiving performance of the radiation electrode 6.

[0110] Fig.17 and Fig.18 The schematic diagram of the structure of two display panels provided in the embodiment of the present invention can be referred to Figure 1 , Figure 2 , Fig.17 and Fig.18In a possible embodiment, the non-display area NA includes an antenna binding area NA1 and a display binding area NA2; the array substrate 4 also includes an antenna binding terminal 18 located in the antenna binding area NA1, and the antenna binding terminal 18 is respectively connected to the antenna unit 5 and the antenna feeding circuit board 20, and the antenna feeding circuit board 20 is used to provide an antenna driving signal for the antenna unit 5; the array substrate 4 also includes a display binding terminal 19 located in the display binding area NA2, and the display binding terminal 19 is respectively connected to the sub-pixel 22 of the display area AA and the display circuit board 21, and the display circuit board 21 is used to provide a display driving signal for the sub-pixel 22; the antenna binding area NA1 and the display binding area NA2 are located on the same side of the display area AA, or the antenna binding area NA1 and the display binding area NA2 are located on different sides of the display area AA.

[0111] like Figure 1 , Figure 2 , Fig.17 and Fig.18 As shown, the display panel further includes an antenna binding terminal 18, an antenna feed circuit board 20, a display binding terminal 19 and a display circuit board 21. The antenna binding terminal 18 is disposed in the antenna binding area NA1 of the non-display area NA, and the antenna binding terminal 18 is used to electrically connect the antenna feed circuit board 20 and the antenna unit 5, so that the antenna feed circuit board 20 can transmit the antenna drive signal to the antenna unit 5. The display binding terminal 19 is used to electrically connect the display circuit board 21 and each sub-pixel 22 in the display area AA, so that the display circuit board 21 can transmit the display drive signal to each sub-pixel 22.

[0112] Exemplary, reference Fig.17 In the embodiment of the present application, the antenna binding area NA1 and the display binding area NA2 can be arranged in the non-display area NA on the same side of the display area AA, for example Fig.17 As shown, the display binding area NA2 and the antenna binding area NA1 are both located in the non-display area NA below the display panel, but are not limited to this. At this time, the radiation electrode 6, the antenna binding terminal 18, and the display binding terminal 19 are located in the non-display area NA on the same side of the display panel. The advantage of this setting method is that it is only necessary to set a binding step in the non-display area NA on one side of the display panel, and there is no need to set a binding step on the other side, which is conducive to achieving a narrow frame of the display panel. Among them, the size of the binding step can be set according to the actual situation, for example, it can be set to mm level, but is not limited to this.

[0113] For example, please refer to Figure 1 and Fig.18 In the embodiment of the present application, the antenna binding area NA1 and the display binding area NA2 may also be arranged in the non-display area NA on different sides of the display area AA, for example Figure 1As shown, the display binding area NA2 is set in the non-display area NA below the display panel, and the antenna binding area NA1 is set in the upper non-display area NA on the opposite side of the display binding terminal 19; or as shown Fig.18 As shown, the display binding area NA2 is arranged in the non-display area NA below the display panel, and the antenna binding area NA1 is arranged in the non-display area NA on the left side of the display area AA. The antenna binding area NA1 and the display binding area NA2 are arranged in the non-display areas NA on different sides, and the distance between the antenna binding terminal 18 and the display binding terminal 19 is relatively far, so as to avoid the binding processes of the display circuit board 21 and the antenna feed circuit board 20 affecting each other and causing the problem of circuit board damage; in addition, the arrangement density of the display binding terminal 19 and the antenna binding terminal 18 can be appropriately reduced, which is conducive to reducing the difficulty of preparing the binding terminals. Among them, the antenna binding terminal 18 and the display binding terminal 19 are both arranged on the array substrate 4. After the antenna feed circuit board 20 and the display circuit board 21 are respectively bound, the antenna feed circuit board 20 and the display circuit board 21 can be bent to the side of the backlight module 1 away from the array substrate 4 for fixation (such as Figure 2 ). Fig.17 and Fig.18 The display circuit board 21 and the antenna feed circuit board 20 are not bent to the back of the display panel.

[0114] Fig.19 A schematic diagram of another display panel provided by an embodiment of the present invention, referring to Fig.19 In this embodiment, the antenna binding area NA1 and the display binding area NA2 are located on the same side of the display area AA, and the antenna feeding circuit board 20 and the display circuit board 21 are the same circuit board.

[0115] Specifically, Fig.19 In the illustrated embodiment, when the display binding area NA2 and the antenna binding area NA1 are located in the non-display area NA on the same side, the antenna feed circuit board 20 and the display circuit board 21 can be set to the same circuit board, that is, the antenna binding terminal 18 and the display binding terminal 19 are electrically connected to the same circuit board. For example, the display circuit board 21 can be reused as the antenna feed circuit board 20, and an antenna feeding module can be added to the display circuit board 21. In this way, only one binding process is required, which can simplify the binding process and reduce the difficulty of binding. The display binding area NA2 and the antenna binding area NA1 shown in the figure are both located in the non-display area NA below the display panel, and the actual setting method is not limited to this. In other embodiments, the display binding area NA2 and the antenna binding area NA1 may both be located in the non-display area NA above or on the side.

[0116] You can continue to refer to Fig.17 In other possible embodiments, the antenna binding area NA1 and the display binding area NA2 are located on the same side of the display area AA, and the antenna feeding circuit board 20 and the display circuit board 21 are different circuit boards.

[0117] Specifically, Fig.17 As shown in FIG. 1 , the display bonding area NA2 and the antenna bonding area NA1 are still arranged in the non-display area NA on the same side. Fig.19 What is different from the illustrated embodiment is that, in this embodiment, the antenna feed circuit board 20 and the display circuit board 21 are different circuit boards used independently of each other, that is, the antenna binding terminal 18 and the display binding terminal 19 are electrically connected to different circuit boards respectively.

[0118] Those skilled in the art will appreciate that, in general, the antenna feed circuit board 20 needs to be provided with a double metal layer, one metal layer is used to set a microstrip line, and the other metal layer is used for grounding, so as to achieve transmission of radio frequency signals, while the display circuit board 21 can be provided as a single-layer circuit board. In this embodiment, by providing the antenna feed circuit board 20 and the display circuit board 21 as different circuit boards, there is no need to customize additional circuit boards according to the different signal transmission requirements of the antenna feed circuit board 20 and the display circuit board 21. Both the display circuit board 21 and the antenna feed circuit board 20 can adopt conventional circuit boards, which helps to reduce costs.

[0119] Optional, you can continue to refer to Fig.17 and Fig.19 In a possible embodiment, the antenna binding area NA1 and the display binding area NA2 are arranged along a first direction; the multiple display binding terminals 19 of the display binding area NA2 are arranged along a first direction X; the multiple antenna binding terminals 18 of the antenna binding area NA1 are arranged along the first direction X; the first direction X is perpendicular to the thickness direction Z of the display panel, and the first direction X intersects with the direction from the display area AA to the non-display area NA.

[0120] Specifically, Fig.17 and Fig.19 As shown, in general, a plurality of binding terminals are provided in the binding area. When the display binding area NA2 and the antenna binding area NA1 are located on the same side of the display area AA, and the display circuit board 21 and the antenna feed circuit board 20 are different circuit boards, the antenna binding area NA1 and the display binding area NA2 can be provided along the first direction X. And the plurality of antenna binding terminals 18 in the antenna binding area NA1 are also arranged along the first direction X, and the plurality of display binding terminals 19 in the display binding area NA2 are also arranged along the first direction X. The first direction X may be parallel to the extension direction of the display panel, and the first direction X intersects with the direction of the display panel display area AA pointing to the non-display area NA where the binding area is located (vertical in the figure, but not limited to this). Under this setting, the antenna feed circuit board 20 and the display circuit board 21 have the same binding direction, and a binding step only needs to be provided in the non-display area NA on one side of the display panel, and no binding step is required on the other sides, which is conducive to realizing a narrow bezel of the display panel.

[0121] Fig. 20 A schematic diagram of the structure of another display panel provided by an embodiment of the present invention, Fig. 20 In the illustrated embodiment, the antenna binding area NA1 and the display binding area NA2 are still arranged along the first direction X; the multiple display binding terminals 19 of the display binding area NA2 are arranged along the first direction X; the multiple antenna binding terminals 18 of the antenna binding area NA1 are arranged along the second direction Y; the first direction X and the second direction Y are both perpendicular to the thickness direction Z of the display panel, and the first direction X intersects with the direction from the display area AA to the non-display area NA, and the second direction Y intersects with the first direction X.

[0122] Specifically, Fig. 20 In the embodiment shown, the antenna binding area NA1 and the display binding area NA2 are still arranged along the first direction X; and the plurality of display binding terminals 19 in the display binding area NA2 are aligned with the above Fig.17 The difference lies in the arrangement of the antenna binding terminals 18 in the antenna binding area NA1, such as Fig. 20 As shown, the antenna binding terminal 18 and the display binding terminal 19 are arranged in a different manner. Specifically, the antenna binding terminal 18 can be arranged along a second direction Y intersecting with the first direction X. The first direction X and the second direction Y shown in the figure are perpendicular, and the actual setting is not limited to this. In this setting, the antenna feed circuit board 20 and the display circuit board 21 have different binding directions, which can avoid the binding processes of the display circuit board 21 and the antenna feed circuit board 20 affecting each other and causing the problem of circuit board damage.

The number of antenna units 5, antenna control signal lines 23 and antenna binding terminals 18 can be the same, and there is a one-to-one correspondence between the three, and the radiation electrodes 6 in each antenna unit 5 are electrically connected. One end of the antenna control signal line 23 is electrically connected to the antenna binding terminal 18, and the other end is electrically connected to the radiation electrode 6 in the corresponding antenna unit 5. The antenna feed circuit board 20 transmits the antenna drive signal to the radiation electrode 6 of the antenna unit 5 through the antenna control signal line 23.

[0125] Among them, taking the display panel including two antenna units 5 as an example, different antenna driving signals can be transmitted to the two antenna units 5 respectively, one antenna unit 5 sends a signal to the outside world, and the other antenna unit 5 receives the external signal. Alternatively, antenna driving signals of different polarization modes can be transmitted to the two antenna units 5 respectively; or, antenna driving signals of two different frequencies can be transmitted to the two antenna units 5 respectively to improve the radiation effect of the antenna unit 5. Of course, when multiple antenna units 5 are provided in the display panel, corresponding antenna driving signals can also be transmitted to different antenna units 5 in the above manner.

[0126] Fig.21 The radiation electrode 6 and the ground conductive layer (not shown in the figure) are arranged in different layers. Fig. 22 A schematic diagram of the structure of another display panel provided by an embodiment of the present invention, Fig. 20 In the illustrated embodiment, the radiation electrode 6 and the ground conductive layer 7 may be disposed in the same layer. The ground conductive layer 7 is composed of ground conductive blocks 70 . The ground conductive blocks may be electrically connected via wiring.

[0128] according to Fig.11 As can be seen from the illustrated embodiment, the repeating unit 24 may include a radiation electrode block 61, a feeding line 62, and a first electrode block 71 and a second electrode block 72 respectively located on both sides of the feeding line 62, and the antenna unit 5 may be only one repeating unit 24. In this embodiment, the antenna unit 5 is composed of at least two interconnected repeating units 24. At this time, the radiation electrode blocks 61 in all the repeating units 24 constitute the radiation electrode 6, and the grounding electrode blocks 70 in all the repeating units 24 constitute the grounding conductive layer 7. The antenna unit 5 is formed by using multiple repeating units 24 with the same structure, and the multiple repeating units 24 work simultaneously to improve the gain of the antenna unit 5.

[0129] The radiation electrode blocks 61 of each repeating unit 24 may be connected to each other to form an antenna unit 5. The radiation electrode blocks 61 may be directly electrically connected or electrically connected through metal wiring, which is not limited in the embodiment of the present invention.

[0130] Optional, can still refer to Figure 1 In a possible embodiment, the array substrate 4 further includes an external common electrode line 25; the external common electrode line 25 is located in a region of the non-display area NA except the antenna binding area NA1.

[0131] Specifically, an external common electrode line 25 is also provided in the non-display area NA of the display panel, and the external common electrode line 25 can be used to eliminate static electricity inside the display panel. Those skilled in the art can set the specific position of the external common electrode line 25 according to actual needs, and the embodiment of the present invention does not limit this. However, it should be pointed out that in this embodiment, the vertical projection of the external common electrode line 25 on the array substrate 4 can be set not to overlap with the vertical projection of the antenna binding area NA1 (or the radiation electrode 6) on the array substrate 4. Avoid mutual influence of the signals transmitted between the external common electrode line 25 and the antenna unit 5. Figure 1 Only one outer common electrode line 25 is shown as an example, and the actual arrangement is not limited thereto.
