[0037] Figure 1 is a structural diagram of a first display module provided by an embodiment of the present invention, Figure 2 yes Figure 1 A schematic cross-sectional view along the section line A-A', see Figure 1 and Figure 2 As shown, an embodiment of the present invention provides a display module 10, which includes: multiple display panels 100, the display panel 100 includes a substrate 200; an electrostatic derivation structure 300, the electrostatic derivation structure 300 is located on one side of the substrate 200, and the electrostatic derivation structure 300 includes a first electrostatic division 310 and a second electrostatic division 320 that are electrically connected, and the first electrostatic division 310 and the second electrostatic division 320 are arranged in different layers.

[0038] Among them, reference Figure 1 As shown, the display module 10 includes multiple display panels 100, and the display panels 100 include multiple light-emitting elements (not specifically shown in the figure), which realize the display function of the display panels 100. The display module 10 can achieve a large-scale display effect by splicing multiple display panels 100. Figure 1 In the embodiment, four display panels 100 are arranged in two rows and two columns. The specific number of display panels 100 provided in the display module 10 and the arrangement of the multiple display panels 100 in the display module 10 can be adaptively adjusted according to actual needs, and are not specifically limited in the embodiment of the present invention.

[0039] Furthermore, in the preparation process of the display module 10, there will be processing techniques such as cutting or edging. The existence of related processes will generate friction static electricity, etc. The static electricity will damage the display module 10, and thus cause a loss of yield. In order to ensure the structural stability of the display module 10, an electrostatic derivation structure 300 is provided in the display module 10 to ensure the overall structural stability of the display module 10. Furthermore, the electrostatic derivation structure 300 can also be extended to different display panels 100 in the display module 10, and can also timely derivate the static electricity generated in the display panel 100, so as to better ensure the overall structural stability of the display module 10. Specifically, the electrostatic derivation structure 300 will be connected to the ground wire, so that the transmitted static electricity can be discharged.

[0040] Furthermore, the electrostatic decompression structure 300 includes a first electrostatic decompression section 310 and a second electrostatic decompression section 320, wherein the first electrostatic decompression section 310 and the second electrostatic decompression section 320 are electrically connected, and the static electricity generated in the display module 10 can be discharged sequentially through the first electrostatic decompression section 310 and the second electrostatic decompression section 320. The electrostatic decompression structure 300 provided in the display module 10 is provided at different film layers of the display module 300. Compared with the electrostatic decompression structure existing in the display module 10 being provided at only one film layer structure, the provision of the first electrostatic decompression section 310 and the second electrostatic decompression section 320 reflects the flexibility of the provision position of the electrostatic decompression structure 300, and the electrostatic decompression structure 300 can avoid other provision components in the display module 10, thereby ensuring the stability of the overall structure of the display module 10. Furthermore, the first electrostatic division 310 and the second electrostatic division 320 are connected, which means that while ensuring electrostatic transmission, the electrostatic derivation structure 300 can also be adaptively adjusted according to the characteristics of the film layer in which it is located, thereby improving the reliability of electrostatic derivation of the electrostatic derivation structure 300 and ensuring the overall structural stability and display effect of the display module 10.

[0041] Exemplarily, the display panel 100 includes a circuit structure, such as a pixel circuit and a driving circuit, for driving the light-emitting elements to emit light, thereby achieving the display effect of the display panel 100 and, in turn, the display effect of the display module 10. The circuit structure includes at least one transistor, which is disposed on one side of the substrate 200. The first electrostatic subsection 310 can be disposed on the same layer as the gate electrode of the transistor, and the second electrostatic subsection 320 can be located on a side of the first electrostatic subsection 310 away from the substrate 200, or on a side of the first electrostatic subsection 310 close to the substrate 200. The specific locations of the first electrostatic subsection 310 and the second electrostatic subsection 320 in the display panel 100 can be adaptively adjusted according to actual needs.

[0042] In summary, an embodiment of the present invention provides a display module in which an electrostatic decoupling structure includes a first electrostatic sub-section and a second electrostatic sub-section that are electrically connected. The first electrostatic sub-section and the second electrostatic sub-section are adjusted to different film layers of the display module, thereby providing flexibility in the placement of the electrostatic decoupling structure and facilitating the avoidance of certain structures. Furthermore, the first electrostatic sub-section and the second electrostatic sub-section are connected, meaning that while ensuring electrostatic transmission, the electrostatic decoupling structure can also be adaptively adjusted based on the characteristics of the film layer in which it is located, thereby improving the reliability of the electrostatic decoupling structure and ensuring the overall structural stability and display effect of the display module.

[0043] Figure 3 is a structural diagram of a second display module provided by an embodiment of the present invention, Figure 4 yes Figure 3 A cross-sectional diagram along the section line BB', refer to Figures 1 to 4 As shown, the film layer where the first electrostatic sub-portion 310 is located is located on a side of the film layer where the second electrostatic sub-portion 320 is located close to the substrate 200 .

[0044] Specifically, refer to Figure 2 As shown, along the thickness direction of the display panel 10 , the film layer where the first electrostatic division 310 is located can be closer to the substrate 200 than the film layer where the second electrostatic division 320 is located, reflecting the different-layer arrangement relationship between the first electrostatic division 310 and the second electrostatic division 320 .

[0045] in, Figure 1 and Figure 2 The orthographic projection of the first electrostatic distribution section 310 and the orthographic projection of the second electrostatic distribution section 320 on the substrate 200 shown in FIG. In this regard, the first electrostatic distribution section 310 and the second electrostatic distribution section 320 can be understood as the electrostatic discharge structure 300 extending to different areas of the display module 10, facilitating the timely discharge of static electricity from different areas of the display module 10.

[0046] Optional, reference Figure 3 and Figure 4 As shown, Figure 3 and Figure 4 The orthographic projection of the first electrostatic sub-section 310 on the substrate 200 and the orthographic projection of the second electrostatic sub-section 320 on the substrate 200 at least partially overlap. The first electrostatic sub-section 310 and the second electrostatic sub-section 320 are electrically connected via the through-hole b1. The number and position of the through-hole b1 are not specifically limited in this embodiment of the present invention. Figure 1Only one through hole b1 is shown to demonstrate the electrical connection between the first electrostatic sub-section 310 and the second electrostatic sub-section 320. It can be understood that, when one of the electrostatic sub-sections is configured to conduct static electricity, an additional electrostatic sub-section can be provided to improve the static electricity transmission efficiency of the electrostatic conduction structure 300 and better ensure the reliability and stability of the display module 10.

[0047] Optionally, the line width of the first electrostatic sub-section 310 is greater than or equal to the line width of the second electrostatic sub-section 320 .

[0048] Among them, the first electrostatic division 310 and the second electrostatic division 320 are connected, that is, while ensuring electrostatic transmission, the electrostatic derivation structure 300 can also be adaptively adjusted according to the characteristics of the film layer in which it is located, thereby improving the reliability of electrostatic derivation of the electrostatic derivation structure 300 and ensuring the overall structural stability and display effect of the display module 10.

[0049] Exemplarily, the display panel 100 includes a circuit structure, such as a pixel circuit and a driving circuit, for driving the light-emitting elements to emit light, thereby achieving the display effect of the display panel 100 and further achieving the display effect of the display module 10. The circuit structure includes at least one transistor, which is disposed on one side of the substrate 200. The first electrostatic subdivision 310 can be disposed in the same layer as the gate of the transistor. When the film layer where the first electrostatic subdivision 310 is located on the side of the film layer where the second electrostatic subdivision 320 is located close to the substrate 200, the second electrostatic subdivision 320 can be disposed on the side of the film layer where the transistor gate is located away from the substrate 200. The square resistance of the film layer where the gate is located is generally greater than the square resistance of other metal film layers. In order to ensure the overall signal transmission stability of the electrostatic decoupling structure 300, the line width of the first electrostatic subdivision 310 can be adjusted to be greater than or equal to the line width of the second electrostatic subdivision 320, thereby ensuring the stability and reliability of signal transmission.

[0050] Figure 5 This is a schematic diagram of the structure of the third display module provided by an embodiment of the present invention, referring to Figure 5 As shown, the display module 10 includes a first side n1, a second side n2, a third side n3 and a fourth side n4, the first side n1 and the fourth side n4 are opposite sides of the display module 10, the second side n2 and the third side n3 are opposite sides of the display module 10, the first side n1 is adjacent to the second side n2 and the third side n3 respectively, and the fourth side n4 is adjacent to the second side n2 and the third side n3 respectively; the display module 10 also includes an electrostatic lead-out pad 400 electrically connected to the electrostatic lead-out structure 300, and the electrostatic lead-out pad 400 is close to the fourth side n4; the first electrostatic division 310 is located at the electrostatic lead-out pad 400 near the center 10a of the display module 10.

[0051] For further reference, Figure 5 As shown, the display module 10 includes a first side n1, a second side n2, a third side n3 and a fourth side n4. The first side n1, the second side n2, the third side n3 and the fourth side n4 can be understood as the outline edge of the display module 10. Figure 5 In the figure, the first side n1, the second side n2, the third side n3 and the fourth side n4 are taken as straight lines for illustration. If the display module 10 is an irregular display module 10, the first side n1, the second side n2, the third side n3 and the fourth side n4 may be curves, etc., and the embodiment of the present invention does not specifically limit this.

[0052] For further reference, Figure 5 As shown, the display module 10 also includes an electrostatic lead-out pad 400, wherein the electrostatic lead-out pad 400 is connected to the electrostatic lead-out structure 300. The electrostatic lead-out pad 400 can be understood as the lead-out terminal of the electrostatic lead-out structure 300, which is convenient for realizing the lead-out of static electricity. Optionally, if the display module 10 is a frameless display device, the electrostatic lead-out structure 300 can be overlapped with the side wiring of the display module 10 prepared subsequently through the electrostatic lead-out pad 400, so as to facilitate the guidance of the electrostatic signal to the backlight surface of the display module 10. While not affecting the frameless display effect of the display module 10, the generated electrostatic signal can also be led out to ensure the overall structural stability of the display module 10.

[0053] Furthermore, the static discharge pad 400 is located near the fourth side n4 of the display module 10, and the first static discharge subsection 310 is located on the side of the static discharge pad 400 near the center 10a of the display module 10. Since the static discharge pad 400 is the lead-out terminal of the static discharge structure 300, it is generally located in the lower wiring area of the display module 10. Therefore, the first side n1 can be understood as the frame wiring of the lower wiring area of the display module 10. The lower wiring area of the display module 10 contains a large number of signal wirings (not shown in the figure), such as scan signal lines or data signal lines. Therefore, during the production process of the display module 10, there is a risk of static electricity generation in this area, which in turn affects the overall stability of the display module 10. By locating the first static discharge subsection 310 in this area, the generated static electricity can be discharged in a timely manner, ensuring the stability of this area. It should be noted that the first static discharge subsection 310 and the aforementioned signal wiring must be insulated to prevent the static discharge structure 300 from interfering with normal signals. Therefore, it is necessary to ensure that the first electrostatic sub-section 310 and the signal lines are arranged on different layers. The second electrostatic sub-section 320 is arranged so as not to interfere with the signal lines in the lower wiring area of the display module 10. To achieve a thin design for the display module 10, the second electrostatic sub-section 320 can be arranged on the same layer as the signal lines arranged in the lower wiring area. This can also ensure the balance of signal wiring in the display module 10. Moreover, the second electrostatic sub-section 320 and the signal lines can be manufactured simultaneously during the manufacturing process, reducing the overall manufacturing cost of the display module 10.

[0054] Figure 6 is a structural diagram of a fourth display module provided by an embodiment of the present invention, Figure 7 yes Figure 6 A cross-sectional diagram along the section line C-C', refer to Figure 6 and Figure 7 As shown, the second electrostatic division 320 includes a first electrostatic trace 321, a second electrostatic trace 322 and a third electrostatic trace 323. The first electrostatic trace 321 is close to the first side n1, the second electrostatic trace 322 is close to the second side n2, and the third electrostatic trace 323 is close to the third side n3. The first electrostatic trace 321 and the first electrostatic division 310 extend along the first direction X1, and the second electrostatic trace 322 and the third electrostatic trace 323 extend along the second direction X2. The first electrostatic trace 321 is electrically connected to the second electrostatic trace 322 and the third electrostatic trace 323, respectively, and the first electrostatic division 310 is electrically connected to the second electrostatic trace 322 and the third electrostatic trace 323, respectively. The first direction X1 and the second direction X2 intersect and are parallel to the plane where the substrate 200 is located.

[0055] For further reference, Figure 6As shown, the second electrostatic section 320 includes a first electrostatic trace 321, a second electrostatic trace 322 and a third electrostatic trace 323, wherein the first electrostatic trace 321 is close to the first side n1, the second electrostatic trace 322 is close to the second side n2, the third electrostatic trace 323 is close to the third side n3, and the first electrostatic section 310 is close to the fourth side n4. The first electrostatic trace section 310, the first electrostatic trace 321, the second electrostatic trace 322 and the third electrostatic trace 323 surround the display module 10 on all sides, thereby ensuring that the static electricity generated by the display module 10 can be discharged as quickly as possible, thereby ensuring the overall structural stability of the display module 10.

[0056] Specifically, the first electrostatic section 310 and the first electrostatic trace 321 extend along the first direction X1, and the second electrostatic trace 322 and the third electrostatic trace 323 extend along the second direction X2. The first direction X1 can be understood as Figure 6 The horizontal direction in the second direction X2 can be understood as Figure 6 The first electrostatic wiring subsection 310, the first electrostatic wiring 321, the second electrostatic wiring 322, and the third electrostatic wiring 323 are arranged around the display module 10 and electrically connected in sequence. This ensures that the static electricity generated in the display module 10 can be efficiently discharged, thereby ensuring the stability and reliability of the display module 10.

[0057] Figure 8 is a structural diagram of a fourth display module provided by an embodiment of the present invention, Figure 9 yes Figure 8 A cross-sectional diagram along the section line D-D', refer to Figures 6 to 9 As shown, the display module 10 includes a data signal line 510 and a data signal lead-out pad 500, and the data signal line 510 is electrically connected to the data signal lead-out pad 500; the first electrostatic section 310 extends along the first direction X1, the data signal line 510 extends along the second direction X2, and the electrostatic lead-out pad 400 and the data signal lead-out pad 500 are arranged along the first direction X1.

[0058] For further reference, Figures 6 to 9 As shown, the display module 10 also includes a data signal lead-out pad 500 and a data signal line 510. In fact, the data signal provided by the data signal line 510 is transmitted to the pixel circuit (not specifically shown in the figure) of each display panel 100 in the display module 10. The pixel circuit can drive the light-emitting element (not specifically shown in the figure) to perform light-emitting display according to the acquired signal, thereby realizing the overall display function of the display module 10. Among them, the data signal transmitted in the data signal line 510 is driven by a driver chip (not specifically shown in the figure). The driver chip is bound and connected to the data signal lead-out pad 500, so that the data signal can be transmitted to the data signal line 510 through the data signal lead-out pad 500.

[0059] For further reference, Figure 6 As shown, the electrostatic lead-out pad 400 and the data signal lead-out pad 500 are arranged along the first direction X1. In other words, the electrostatic lead-out pad 400 and the data signal lead-out pad 500 are both arranged at the fourth side n4 of the display module 10. Among them, the electrostatic lead-out pad 400 is electrically connected to the first electrostatic sub-section 310 and is arranged on the same layer, and the data signal lead-out pad 500 and the data signal line 510 located in the lower area are arranged on the same layer. Furthermore, in order to ensure the overall thinness of the display module 10, the second electrostatic sub-section 320 can be arranged on the same layer as the data signal lead-out pad 500. Furthermore, by arranging the wirings that do not affect each other on the same film layer, the balance of the overall wiring setting of the display module 10 can also be improved, and the wirings arranged on the same layer can be prepared synchronously during the preparation process of the display module 10, thereby reducing the process preparation cost of the display module 10.

[0060] For further reference, Figure 6 and Figure 7 As shown, the orthographic projection of the data electrostatic lead-out pad 400 on the substrate 200 and the orthographic projection of the data signal lead-out pad 500 on the substrate 200 may not overlap. Figure 8 and Figure 9 As shown, the orthographic projection of the data electrostatic lead pad 400 on the substrate 200 and the orthographic projection of the data signal lead pad 500 on the substrate 200 can overlap. This shows that the arrangement of the data electrostatic lead pad 400 electrically connected to the first electrostatic subsection 310 is flexible.

[0061] In other words, in the display module 10 provided in the embodiment of the present invention, the electrostatic discharge structure 300 includes, in addition to the second electrostatic sub-section 320 disposed on the same layer as the data signal line 510, a first electrostatic sub-section 310 located on the side of the second electrostatic sub-section 320 closer to the substrate 200. Furthermore, the first electrostatic sub-section 310 in the display module 10 is located near the lower wiring area of the display module 10, while the second electrostatic sub-section 320 surrounds the display module 10 in other directions. The combination of the first electrostatic sub-section 310 and the second electrostatic sub-section 320 can better ensure the overall electrostatic discharge effect of the display module 10. Furthermore, the first electrostatic sub-section 310 and the second electrostatic sub-section 320 disposed on different layers do not require an additional film structure, which can also facilitate a thinner design of the display module 10.

[0062] Figure 10 is a structural diagram of a fourth display module provided by an embodiment of the present invention, Figure 11 yes Figure 10 An enlarged schematic diagram of the F area in the middle, Figure 12 yes Figure 11 A cross-sectional diagram along the section line G-G', refer to Figures 10 to 12 As shown, the electrostatic lead-out structure 300 includes a pad layer 330; the pad layer 330 is located on the side of the first electrostatic division 310 close to the substrate 200, and along the second direction X2, the pad layer 330 is located between adjacent data signal lead-out pads 50, and / or the pad layer 330 is located between the electrostatic lead-out pad 400 and the data signal lead-out pad 500.

[0063] Specifically, refer to Figures 10 to 12 As shown, the electrostatic discharge structure 300 further includes a pad layer 330, wherein the reference Figure 12 As shown, the cushion layer 330 is located on the side of the first electrostatic distribution section 310 that is closest to the substrate 200. The cushion layer 330 ensures the stability of the first electrostatic distribution section 310 within the film layer. For example, the first electrostatic distribution section 310 can be understood as a "bridge" arranged along the first direction X1, and the cushion layer 330 can be understood as a "bridge pier" to prevent the "bridge" from collapsing. Therefore, the cushion layer 330 ensures the stability of the electrostatic discharge structure 300.

[0064] Furthermore, the first electrostatic subsection 310 is positioned near the lower wiring area of the display module 10, where numerous circuits, such as the frame circuit, reside. When the first electrostatic subsection 310 is conducting electrostatic transport, the cushioning layer 330 prevents some static electricity from damaging the circuits located on the fourth side n4, further ensuring the overall structural stability of the display module 10.

[0065] Furthermore, along the second direction X2, the pad layer 330 is located between adjacent data signal lead pads 50, referring to Figure 11 Alternatively, along the second direction X2, the pad 330 is located between the static lead pad 400 and the data signal lead pad 500, as shown in FIG. Figure 11 The middle cushion layer 330 (shown as 330a in the figure) has flexibility in the specific location of the cushion layer 330.

[0067] For further reference, Figure 13 As shown, the data signal lines 510 include a first-color data signal line 511, a second-color data signal line 512, and a third-color data signal line 513. The first-color data signal line 511 is connected to the corresponding pixel circuit, thereby driving the corresponding first-color light-emitting element to emit light for display. Similarly, the second-color data signal line 512 is connected to the corresponding pixel circuit, thereby driving the corresponding second-color light-emitting element to emit light for display. The third-color data signal line 513 is connected to the corresponding pixel circuit, thereby driving the corresponding third-color light-emitting element to emit light for display. For example, the first color can be red, the second color can be green, and the third color can be blue. This can achieve a color display effect for the display module 10. Furthermore, different data signal lines 510 are connected to different data signal lead pads 500. Correspondingly, the data signal lead pads 500 include a first-color lead pad 500a, a second-color lead pad 500b, and a third-color lead pad 500c.

[0068] Furthermore, the first light-emitting color data signal line 511, the second light-emitting color data signal line 512 and the third light-emitting color data signal line 513 respectively transmit different data signals, so the corresponding first light-emitting color lead-out pad 500a, the second light-emitting color lead-out pad 500b and the third light-emitting color lead-out pad 500c also have different tolerances to static electricity.

[0069] Furthermore, the pad layer 330 includes a first pad layer 331 and a second pad layer 332.

The provision of the pad layer 330 can help prevent static electricity from damaging surrounding circuits. Therefore, the pad layer 330 can be configured differently based on the different static tolerances of the first color lead-out pad 500a, the second color lead-out pad 500b, and the third color lead-out pad 500c. Specifically, the overlapping area between the first pad layer 331 and the first electrostatic subsection 310 is greater than the overlapping area between the second pad layer 332 and the first electrostatic subsection 310. By making detailed adjustments to the pad layer 220, the overall static electricity transmission of the display module 10 can be more reliable, ensuring the overall stability and reliability of the display module 10. Furthermore, the remaining pad layers 330 can also be comprehensively adjusted based on the distances to the remaining first-color lead-out pads 500a.

[0071] As described above, the first electrostatic distribution section 310 is disposed at the fourth side n4 of the display module 10, that is, the first electrostatic distribution section 310 is disposed in the wiring area below the display module 10. The provision of the first electrostatic distribution section 310 facilitates the conduction of static electricity, and the padding layer 330 disposed on the side of the first electrostatic distribution section 310 near the substrate 200 helps prevent static electricity from causing "explosion" to surrounding circuits during transmission.

[0072] Furthermore, a hollow unit 310a can be added to the first electrostatic subsection 310. The added hollow unit 310a does not affect the electrostatic transmission in the first electrostatic subsection 310, and can also better avoid the situation where the surrounding circuits are "damaged" during the electrostatic transmission process.

The provision of the pad layer 330 can help prevent static electricity from damaging surrounding circuits. The hollow section 310 provided within the first electrostatic section 310 can further prevent static electricity from damaging surrounding circuits. Therefore, the hollow sections 310 can be differentiated based on the different static electricity tolerances of the first color lead-out pad 500a, the second color lead-out pad 500b, and the third color lead-out pad 500c. Specifically, the total area of the orthographic projection of the first hollow portion 310a1 onto the substrate 200 is greater than the total area of the orthographic projection of the second hollow portion 310a2 onto the substrate 200. By making detailed adjustments to the hollow portion 310a, the overall transmission of static electricity by the display module 10 can be ensured to be more reliable, thereby ensuring the overall stability and reliability of the display module 10.

[0075] Continue to refer Figure 10 、 Figure 15 and Figure 16As shown, the first hollow section 310a1 includes at least one first hollow substructure 310a11, and the second hollow section 310a2 includes at least one second hollow substructure 310a21; the number of first hollow substructures 310a11 is greater than the number of second hollow substructures 310a21, and / or the area of the first hollow substructure 310a11 is greater than the area of the second hollow substructure 310a21.

For example, the first electrostatic distribution section 310 can be understood as a "bridge" arranged along the first direction X1, and the reinforcing substructure 340 can also be understood as a "bridge pier" to prevent the "bridge" from collapsing. Therefore, the placement of the reinforcing substructure 340 also ensures the stability of the electrostatic discharge structure 300.
