[0036] Among them, further reference Figures 1 to 4 As shown, the display module 10 includes a display panel 100, and the display panel 100 includes a display portion 100a, and the display portion 100a is located in the display light-emitting portion of the display panel 100, and the light-emitting element (not specifically shown in the figure) arranged in the display portion 100a is driven to perform light-emitting display, thereby realizing the display function of the display module 10 as a whole. Figures 1 to 4 As shown, the display panel 100 further includes a bending portion 100b and a binding portion 100c, wherein the bending portion 100b can be bent, and the bending portion 100b drives the binding portion 100c to be placed on the non-light-emitting side of the display panel 100 by bending. It should be noted that Figure 1 It is used to show the relative positional relationship between the display portion 100a, the bending portion 100b and the binding portion 100c, and the film layer structure is unfolded and shown without bending the bending portion 100b; Figures 2 to 4 FIG. 1 is a side cross-sectional view showing a partial structure of the module 10 , in which the bent portion 100 b is bent. Figures 2 to 4 The bending portion 100b is a bent arc structure, the binding portion 100c is connected to the display portion 100a through the bending portion 100b, and the binding portion 100c is bent to the non-light-emitting side of the display panel 100 through the bending portion 100b, so that the lower frame area in the display module 10 can be reduced and the display screen ratio can be increased. Figure 1 As shown, on the non-light-emitting side of the display panel 100, the binding portion 100c is provided with a plurality of binding terminals (refer to Figure 1The bonding terminals 110 and 120 shown in FIG. 1 are electrically connected to the pads 100A1 of the driver chip 100A and the pads 100B1 of the flexible circuit board 100B, respectively. The signals provided by the driver chip 100A and the signals provided by the flexible circuit board 100B are transmitted to the display panel 100 through the bonding terminals, thereby realizing the display function of the display panel 100.
[0037] For further reference, Figures 2 to 4 As shown, the display module 10 further includes a support layer 200, and the support layer 200 includes a first support sub-section 210 and a second support sub-section 220. Along the first direction X1, the first support sub-section 210 is located on the side of the display part 100a close to the binding part 100c, and the second support sub-section 220 is located on the side of the binding part 100c close to the display part 100a. It can be understood that the first support sub-section 210 is used to support the display part 100a, and the second support sub-section 220 is used to support the binding part 100c. At the same time, the display module 10 further includes a support structure 300. Along the first direction X1, the support structure 300 is located between the first support sub-section 210 and the second support sub-section 220, that is, the support structure 300 is located inside the area defined by the first support sub-section 210 and the second support sub-section 220. The first supporting section 210 and the second supporting section 220 can be understood as the back plate of the display module 10 , and the supporting layer 200 and the supporting structure 300 both play a supporting role to ensure the stability of the overall structure of the display module 10 .
[0038] Furthermore, the display module 10 further includes an adhesive structure 400. Along the first direction X1, the adhesive structure 400 is also located between the first supporting section 210 and the second supporting section 220. That is, the adhesive structure 400 and the supporting structure 300 are both located within the area defined by the first supporting section 210 and the second supporting section 220. Figures 2 to 4As shown, along the second direction X2, the adhesive structure 400 is located on the side of at least part of the support structure 300 close to the bending portion 100b. The bending portion 100b drives the binding portion 100c to bend to the non-light-emitting side of the display panel 100, so the bending portion 100b and the binding portion 100c will have stress deflected toward the non-light-emitting side, and the binding portion 100c is located on the side of the second support section 220 away from the display section 100a, so the stress generated by the binding portion 100c and the bending portion 100b will cause the second support section 200 to have a tendency to move away from the support structure 300, or in other words, it will cause the support layer 200 to have a risk of peeling, affecting the overall structural stability of the display module 10. The adhesive structure 400 disposed on the first supporting section 210 and the second supporting section 220 has a certain viscosity, which can have a strong adhesion and fixation effect on the second supporting section 220, thereby ensuring the structural stability of the supporting layer 200 and avoiding the peeling of the supporting layer 200. At the same time, the adhesive structure 400 can also provide corresponding supporting force, thereby ensuring the overall structural stability of the display module 10.
[0039] For further reference, Figures 2 to 4 As shown, along the first direction X1, the support layer 200 covers the adhesive structure 400. Specifically, the projection of the support layer 200 in the first direction X1 covers the projection of the adhesive structure 400 in the first direction X1; in other words, the adhesive structure 400 arranged in the first support section 210 and the second support section 220 does not exceed the defined area of the first support section 210 and the second support section 220; in other words, the end of the first support section 210 close to the bending section 100b is closer to the bending section 100b than the end of the adhesive structure 400 close to the bending section 100b. In the prior art, a support structure is generally arranged in the area corresponding to the arrangement of the adhesive structure 400 provided in the embodiment of the present invention. The support structure generally includes a film layer such as foam and copper foil that is mostly used for support. The thickness of the adhesive layer for adhesion to the second support section is relatively small, resulting in insufficient adhesion to the second support section, resulting in a greater risk of warping and peeling of the second support section. The embodiment of the present invention can be understood as shortening the length of at least part of the support structure 300 in the second direction X2, and setting the adhesive structure 400 in the area left after the shortening, so that the adhesive structure 400 can have a larger thickness and stronger adhesion, ensuring that the support layer 200 will not be peeled off due to the existing stress, thereby realizing the reliability of the structure of the display module 10.
[0040] For further reference, Figures 2 to 4As shown, along the second direction X2, the adhesive structure 400 is located on the side of at least part of the support structure 300 close to the bending portion 100b, wherein the support structure 300 may include multiple film layer structures, such as mesh glue, foam or copper foil, etc., and the adhesive structure 400 is located on the side of part of the film layer of the support structure 300 close to the bending portion 100b. In this regard, it can also be understood that, with reference to Figures 2 to 4 As shown, along the first direction X1, the thickness of the adhesive structure 400 can be set differently. The specific thickness value of the adhesive structure 400, or the film layer of the adhesive structure 400 in the support structure 300 close to the side of the bending portion 100b, can be set differently according to the needs of the display module 10, reflecting the diverse setting methods of the adhesive structure 400.
[0041] Furthermore, the adhesive structure 400 provided in the embodiment of the present invention is located within the limited range of the first supporting section 210 and the second supporting section 220, or Figure 2 , Figure 3 and Figure 4 Taking the structure shown as an example, it is located below the second supporting section 220. Different from the protective glue filled in the bending radius limiting area of the bending section 100b, the main function of the adhesion structure 400 provided in the embodiment of the present invention is to provide a greater adhesion force to the second supporting section 220, ensuring that it remains stable and does not warp under the action of the greater adhesion force.
[0042] Optional, reference Figures 2 to 4 As shown, the display module 10 also includes a film structure such as a polarizer 600, an optical glue 700, a cover plate 800 and a protective layer 900. Among them, the polarizer 600, the optical glue 700 and the cover plate 800 are located on the side of the display part 100a away from the binding part 100c, and the protective layer 900 at least covers the bending part 100b. The polarizer 600 is used to reduce the light incident on the display module 10 and then emitted from the display module 10 again, which can reduce the interference of the external ambient light on the light emitted by the display module 10 itself, thereby ensuring the overall display effect of the display module 10. The optical glue 700 is used to bond the overall structure to ensure the overall structural stability of the display module 10. The cover plate 800 and the protective layer 900 are used to protect the structure of the display module 10, thereby ensuring the reliability of the display module 10. For different display modules 10, other film layers can be adaptively added, and the embodiments of the present invention will not be described one by one.
[0043] In summary, in the display module provided by the embodiment of the present invention, a supporting structure and an adhesive structure are arranged between the first supporting section and the second supporting section. The supporting layer and the supporting structure are used to provide supporting force for the overall structure of the display module. The adhesive structure ensures the stability of the structure of the first supporting section and the second supporting section to avoid peeling of the supporting layer, thereby better ensuring the overall structural stability of the display module.
[0044] Continue to refer Figures 2 to 4 As shown, the support structure 300 includes a first adhesion layer 310, a buffer layer 320 and a conductive layer 330 stacked along a first direction X1, and the first adhesion layer 310 is located on a side of the buffer layer 320 close to the first support section 210; along the second direction X2, the adhesion structure 400 is at least located on a side of the conductive layer 330 close to the bending portion 100b.
[0045] Further, combined with Figures 2 to 4 As shown, the support structure 300 includes a first adhesive layer 310, a buffer layer 320 and a conductive layer 330. Specifically, the first adhesive layer 310 is located on the side of the first support sub-section 210 away from the display section 100a. The first adhesive layer 310 can be understood as a grid glue, which is used to adhere the first support sub-section 210 to the buffer layer 320 in the support structure 300. The buffer layer 320 is located on the side of the first adhesive layer 310 away from the first support sub-section 210. The buffer layer 320 can be understood as foam or other highly flexible structures. The buffer layer 320 can buffer the impact force or stress on the display module 10. The conductive layer 330 is located on the side of the buffer layer 320 away from the first adhesion layer 310. The conductive layer 330 can be copper foil or other structures with good thermal conduction or electrostatic conduction effects. On the one hand, the conductive layer 330 has a certain hardness to ensure the structural stability of the support structure 300. On the other hand, the conductive layer 330 has thermal conductivity and electrical conductivity, which can transmit heat and conduct static electricity, thereby avoiding the influence of heat and static electricity on the display module 10, thereby ensuring the structural stability and reliability of the display module 10.
[0046] In combination with different configurations of the support structure 300 , the specific configuration of the adhesion structure 400 is diverse, as shown below:
[0047] Optional, continue to refer to Figure 2 As shown, along the second direction X2, the adhesive structure 400 is located on a side of the support structure 300 close to the bending portion 100b.
[0048] The adhesive structure 400 in the display module 10 can be arranged at a position as follows: Figure 2 As shown, along the second direction X2, the adhesive structure 400 is located on a side of the entire support structure 300 close to the bending portion 100b. Specifically, along the second direction X2, the adhesive structure 400 includes a partial area located on a side of the first adhesive layer 310 close to the bending portion 100b, a partial area located on a side of the buffer layer 320 close to the bending portion 100b, and a partial area located on a side of the conductive layer 330 close to the bending portion 100b.
[0049] For further reference, Figure 2As shown, the adhesive structure 400 is arranged in affixed relation with the second supporting section 220, and the adhesive structure 400 is also arranged in affixed relation with the first supporting section 210, so the thickness of the adhesive structure 400 is set to be maximized. The viscosity of the adhesive structure 400 can be enhanced according to the set thickness, thereby ensuring that the structural stability between the first supporting section 210 and the second supporting section 220 is stronger, thereby ensuring the overall structural stability of the display module 10.
[0050] Optional, continue to refer to Figure 3 As shown, along the first direction X1 , the adhesive structure 400 at least partially overlaps the first adhesive layer 310 .
[0051] Furthermore, the location of the adhesive structure 400 in the display module 10 can be as follows: Figure 3 As shown, along the second direction X2, the adhesive structure 400 is located on the side of the buffer layer 320 and the conductive layer 330 close to the bending portion 100b. At the same time, the adhesive structure 400 is located on the side of the first adhesive layer 310 close to the second supporting portion 220. Specifically, along the second direction X2, the adhesive structure 400 includes a partial area located on the side of the buffer layer 320 close to the bending portion 100b, and the adhesive structure 400 also includes a partial area located on the side of the conductive layer 330 close to the bending portion 100b.
[0052] For further reference, Figure 3 As shown, along the second direction X2, the extension length of the first adhesive layer 310 is greater than the extension length of the buffer layer 320, and the extension length of the first adhesive layer 310 is also greater than the extension length of the conductive layer 330. The area where the first adhesive layer 310 extends compared to the buffer layer 320 can be used to set the adhesive structure 400. Specifically, one side of the adhesive structure 400 is laminated with the second support section 220, and the other side of the adhesive structure 400 is also laminated with part of the first adhesive layer 310. At this time, the adhesive structure 400 also has a large thickness and good adhesive strength, which prevents the second support section 220 from warping and peeling; at the same time, there is a first adhesive layer 310 between the adhesive structure 400 and the first support section 210, and the first adhesive layer 310 also has a certain viscosity. The structural stability of the first support section 210 and the second support section 220 can be ensured by the first adhesive layer 310 and the adhesive structure 400.
[0053] Combination Figure 3As shown, in the setting area of the adhesive structure 400, considering that the first adhesive layer 310 in the supporting structure 300 also has a certain viscosity, the adhesive structure 400 can be set on the side of the first adhesive layer 310 close to the second supporting section 220. On the one hand, the thickness of the adhesive structure 400 can be reduced and thus the process preparation cost of the adhesive structure 400 can be reduced. At the same time, the stability of the structure between the first supporting section 210 and the second supporting section 220 can be ensured, thereby ensuring the overall structural stability of the display module 10.
[0054] Optional, continue to refer to Figure 4 As shown, along the first direction X1 , the adhesive structure 400 at least partially overlaps the first adhesive layer 310 and the buffer layer 320 .
[0055] Furthermore, the location of the adhesive structure 400 in the display module 10 can be as follows: Figure 4 As shown, along the second direction X2, the adhesive structure 400 is located on the side of the conductive layer 330 close to the bending portion 100b. At the same time, the adhesive structure 400 is located on the side of the buffer layer 320 close to the second supporting portion 220. Specifically, along the second direction X2, the adhesive structure 400 includes a partial area located on the side of the conductive layer 330 close to the bending portion 100b.
[0056] For further reference, Figure 4 As shown, along the second direction X2, the extension length of the first adhesive layer 310 and the buffer layer 320 is greater than the extension length of the conductive layer 330. The adhesive structure 400 can be set in the area where the buffer layer 320 extends compared to the conductive layer 330. Specifically, one side of the adhesive structure 400 is arranged in affixed with the second supporting section 220, and the other side of the adhesive structure 400 is also arranged in affixed with part of the buffer layer 320. The adhesive structure 400 has good adhesive strength to prevent the second supporting section 220 from warping and peeling; at the same time, the buffer layer 320 exists between the adhesive structure 400 and the first supporting section 210, which can ensure that the external force can also be buffered in the area where the adhesive structure 400 is set, thereby ensuring the reliability of the display module 10.
[0057] Combination Figure 4 As shown, by providing the adhesive structure 400, the second supporting section 220 can be effectively prevented from being peeled off. Furthermore, the buffer layer 320 is retained on the side of the adhesive structure 400 close to the first supporting section 210. On the one hand, while ensuring a good adhesion effect to the second supporting section 220, the thickness of the adhesive structure 400 can be reduced, thereby reducing the process preparation cost of the adhesive structure 400. On the other hand, it can ensure that the area where the adhesive structure 400 is provided can also buffer external forces, thereby ensuring the reliability of the display module 10.
[0058] Continue to refer Figures 2 to 4 As shown, the support structure 300 also includes a second adhesive layer 340 located between the conductive layer 330 and the second supporting section 220 along the first direction X1; along the second direction X2, at least part of the adhesive structure 400 is located on the side of the conductive layer 330 and the second adhesive layer 340 close to the bending portion 100b; along the first direction X1, the thickness of the adhesive structure 400 is greater than the thickness of the second adhesive layer 340.
[0059] Furthermore, the support structure 300 also includes a second adhesive layer 340, which is located between the conductive layer 330 and the second supporting section 220, and the second adhesive layer 340 also has a certain viscosity. The second adhesive layer 340 can ensure a stable adhesion relationship between the conductive layer 330 and the second supporting section 220, and prevent the second supporting section 220 from peeling off at the conductive layer 330.
[0060] For further reference, Figures 2 to 4 As shown, along the second direction X2, at least part of the adhesion structure 400 is located on the side of the conductive layer 330 and the second adhesion layer 340 close to the bending portion 100b. In other words, the adhesion structure 400 includes a partial area located on the side of the conductive layer 330 close to the bending portion 100b and a partial area located on the side of the second adhesion layer 340 close to the bending portion 100b, and its thickness is greater than the thickness of the second adhesion layer 340. Compared with the second adhesion layer 340, it has a stronger adhesion strength to the second supporting section 220, thereby ensuring that the second supporting section 220 of this part will not peel off due to warping stress.
[0061] Among them, reference Figures 2 to 4 As shown, along the first direction X1, the thickness of the second adhesive layer 340 is h, referring to Figure 2 As shown, along the first direction X1, the thickness of the adhesive structure 400 is h1, where h1>h; Figure 3 As shown, the thickness of the adhesive structure 400 is h2, where h2>h; Figure 4 As shown, the thickness of the adhesive structure 400 is h3, where h3>h. In general, along the first direction X1, the thickness of the second adhesive layer 340 is less than the thickness of the adhesive structure 400.
[0062] Furthermore, the display module 10 can be thinned by reducing the thickness of the second adhesive layer 340. Specifically, the adhesive structure 400 can ensure the overall structural stability of the display module 10 and prevent the second support section 220 from peeling off at the support structure 300, so the thickness of the second adhesive layer 340 can be reduced, and the display module 10 can be thinned without affecting the structural stability of the display module 10.
[0063] Optionally, when the thickness of the adhesive structure 400 along the first direction X1 is large enough, for example, Figure 2 As shown, when the projection area of the adhesive structure 400 along the first direction X1 is large enough, the display module 10 can ensure the structural stability of the second supporting section 220 only by providing the adhesive structure 400. In this case, the second adhesive layer 340 may not be provided, thereby further reducing the thickness of the display module 10 and better realizing the thin design of the display module 10.
[0064] Continue to refer Figures 2 to 4 As shown, the viscosity coefficient of the adhesive structure 400 is greater than the viscosity coefficient of the second adhesive layer 340 .
[0065] For further reference, Figures 2 to 4 As shown, the support structure 300 includes a second adhesive layer 340 for example, wherein along the second direction X2, the distance between the adhesive structure 400 and the bending portion 100b is smaller than the distance between the second adhesive layer 340 and the bending portion 100b; at the same time, the projection of the adhesive structure 400 to the first direction X1 overlaps with the projection of the binding portion 100c to the first direction X1, so the anti-peeling protection degree of the adhesive structure 400 to the second supporting section 220 is greater than the anti-peeling protection degree of the second adhesive layer 340 to the second supporting section 220, and therefore, adjusting the viscosity coefficient of the adhesive structure 400 to be greater than the viscosity coefficient of the second adhesive layer 340 can better ensure the stability of the overall structure of the display module 10.
[0066] Figure 5 is a cross-sectional schematic diagram of a fourth display module provided by an embodiment of the present invention, Figure 6 is a cross-sectional schematic diagram of a fifth display module provided by an embodiment of the present invention, Figure 7 is a cross-sectional schematic diagram of a sixth display module provided by an embodiment of the present invention, referring to Figures 5 to 7 As shown, the adhesion structure 400 includes a first adhesion section 410 and a second adhesion section 420 connected to each other; along the first direction X1, the first adhesion section 410 is located between the conductive layer 330 and the second supporting section 220; along the second direction X2, the second adhesion section 420 is located on the side of the conductive layer 330 and the first adhesion section 410 close to the bending section 100b, and the thickness of the second adhesion section 420 is greater than the thickness of the first adhesion section 410; the first adhesion section 410 is reused as the second adhesion layer 340.
[0067] Specifically, refer to Figures 5 to 7 As shown, the adhesive structure 400 includes a first adhesive sub-section 410, which is located between the conductive layer 330 and the second supporting sub-section 220 along the first direction X1, and is used to achieve adhesion between the conductive layer 330 and the second supporting sub-section 220. Further, the setting position of the first adhesive sub-section 410 is equivalent to Figures 2 to 7 The second adhesive layer 340 is shown, and thus the first adhesive section 410 can be reused as the second adhesive layer 340 .
[0068] Specifically, refer to Figures 5 to 7 As shown, the adhesive structure 400 also includes a second adhesive section 420, which is located at least on one side of the conductive layer 330 and the first adhesive section 410 close to the bending portion 100b along the second direction X2, that is, along the second direction X2, the distance between the second adhesive section 420 and the bending portion 100b is smaller than the distance between the first adhesive section 410 and the bending portion 100b; at the same time, the projection of the second adhesive section 420 to the first direction X1 overlaps with the projection of the binding portion 100c to the first direction X1, so the anti-peeling protection degree of the second adhesive section 420 to the second supporting section 220 is greater than the anti-peeling protection degree of the first adhesive section 410 to the second supporting section 220, and therefore, the thickness of the second adhesive section 420 is adjusted to be greater than the thickness of the first adhesive section 410, so as to ensure the stability of the film layer at the second adhesive section 420, and thus the stability of the overall structure of the display module 10 can be better ensured.
[0069] Furthermore, the first adhesive portion 410 is reused as the second adhesive layer 340 , and the first adhesive portion 410 and the second adhesive portion 420 are made of the same material and can be simultaneously manufactured and integrated, thereby reducing the manufacturing process cost of the display module 10 .
[0070] Continue to refer Figures 2 to 7 As shown, along the first direction X1, the adhesive structure 400 overlaps with at least a portion of the binding portion 100c.
[0071] Among them, there is an overlapping area between the orthographic projection of the adhesive structure 400 in the first direction X1 and the orthographic projection of the binding portion 100c in the first direction X1. Since the binding portion 100c is bent by the bending portion 100b and driven to the non-light-emitting side of the display panel 100, the position of the binding portion 100c is more likely to cause the second supporting section 220 to warp and then peel off, affecting the structural stability of the display module 10. The adhesive structure 400 has good adhesive strength and can effectively prevent the second supporting section 220 from warping and peeling off. In the second supporting section 220, the area that overlaps with the binding portion 100c along the first direction X1 has a more obvious tendency to warp and peel off. Therefore, the setting area of the adhesive structure 400 is adjusted to overlap with a partial area of the binding portion 100c, thereby more effectively ensuring the structural stability of the second supporting section 220. Specifically, it overlaps with at least a partial area of the binding portion 100c along the first direction X1, for example, referring to Figure 2 The middle aa region can ensure the overall structural stability of the display module 10.
[0072] Continue to refer Figures 2 to 7 As shown, the binding portion 100c includes a binding end portion 100c1. Along the second direction X2, the binding end portion 100c1 is the end portion of the binding portion 100c away from the bending portion 100b. Along the first direction X1, the adhesive structure 400 overlaps with the binding end portion 100c1.
[0073] Specifically, refer to Figures 2 to 7 As shown, the binding portion 100c includes a binding end portion 100c1, and the binding end portion 100c1 is located on the side of the binding portion 100c away from the bending portion 100b. The binding end portion 100c1 can be understood as the end position of the display panel 100 at the binding portion 100c. Further, the bending of the bending portion 100b drives the binding portion 100c to be on the non-light-emitting side of the display panel 100. Due to the bending of the structure, stress biased toward the non-light-emitting side will occur, which in turn drives the second supporting section 220 to peel off, thereby affecting the structural stability of the display module 10. The adhesive structure 400 provided in the embodiment of the present invention has strong viscosity, which can adhere the second supporting section 220 to prevent the second supporting section 220 from peeling off.
[0074] Furthermore, the binding end portion 100c1 is at the end of the binding end portion 100c1. If the binding portion 100c of the display panel 100 drives the second supporting portion 220 to peel off, it should be from the binding end portion 100c1 that the second supporting portion 220 is gradually driven to detach from the supporting structure 300 in sequence. The adhesive structure 400 provided in the embodiment of the present invention overlaps with the binding end portion 100c1 along the first direction X1, or the orthographic projection of the adhesive structure 400 to the first direction X1 overlaps with the orthographic projection of the binding end portion 100c1 to the first direction X1. The adhesive structure 400 prevents the second supporting portion 220 from peeling off from the supporting structure 300 from the source, thereby ensuring the structural stability of the second supporting portion 220 and the overall structural stability of the display module 10.
[0075] Continue to refer Figure 2 As shown, the area of the binding portion 100 c is S1, and the area of the binding portion 100 c overlapping with the adhesive structure 400 in the first direction X1 is S2; wherein S2 / S1≥50%.
[0076] Furthermore, the area of the binding portion 100c is S1, and the area of the region where the adhesive structure 400 overlaps with the binding portion 100c along the first direction X1 is S2. When the overlapping area S2 is larger, the adhesion effect of the adhesive structure 400 on the second supporting portion 220 is better, and the second supporting portion 220 can be ensured not to be peeled off. Specifically, S1 and S2 can satisfy: S2 / S1≥50%. Figure 2As shown, area aa can be understood as the area where the adhesive structure 400 overlaps with the binding portion 100c along the first direction X1, and area bb can be understood as the area corresponding to the binding portion 100c. By increasing the overlapping area between the adhesive structure 400 and the binding portion 100c, the structural stability of the second supporting section 220 can be further ensured, thereby improving the overall structural stability of the display module 10.
[0077] Figure 8 is a cross-sectional schematic diagram of a seventh display module provided by an embodiment of the present invention, Fig. 9 is a top view schematic diagram of a conductive layer provided by an embodiment of the present invention, referring to Figure 1 , Figure 8 and Fig. 9 As shown, the conductive layer 330 includes a first conductive section 331 and a second conductive section 332. Along the second direction X2, the second conductive section 332 is located on a side of the first conductive section 331 close to the bending portion 100b; the second conductive section 332 includes a hollow 332a, and the hollow 332a penetrates the conductive layer 330; the adhesion structure 400 is bonded to the second support section 220 through the hollow 332a.
[0078] Among them, reference Figure 8 and Fig. 9 As shown, the conductive layer 330 may include a first conductive sub-portion 331 and a second conductive sub-portion 332, and along the second direction X2, the second conductive sub-portion 332 is located on a side of the first conductive sub-portion 331 close to the bending portion 100b. Further, along the first direction X1, the projection of the first conductive sub-portion 331 does not overlap with the projection of the adhesive structure 400, and the projection of the second conductive sub-portion 332 overlaps with the projection of the adhesive structure 400.
[0079] For further reference, Figure 8 and Fig. 9 As shown, the second conductive sub-section 332 includes a hollow 332a, and the hollow 332a penetrates the conductive layer 330. The adhesive structure 400 can be bonded to the second supporting sub-section 220 through the hollow 332a, thereby ensuring a good adhesion effect on the second supporting sub-section 220 and ensuring the structural stability of the second supporting sub-section 220. The conductive layer 330 can be a copper foil, which has good thermal conductivity and electrical conductivity. The conductive layer 330 can conduct away the heat and static electricity conducted thereto, thereby ensuring the reliability of the display module 10. For example, refer to Figure 8 As shown, the second conduction division 332 overlaps with the driver chip 100A disposed on the binding portion 100c. The driver chip 100A generates heat and static electricity when working. The setting of the second conduction division 332 is conducive to timely discharge of this part of heat and static electricity, thereby ensuring the reliability of the display module 10 and improving the display effect of the display module 10.
[0080] Continue to refer Figure 8 and Fig. 9 As shown, the second conductive section 332 further includes grid lines 332b defining hollows 332a; the sum of the coverage areas of the hollows 332a is greater than the coverage area of the grid lines 332b.
[0081] For further reference, Figure 8 and Fig. 9 As shown, the second conductive sub-section 332 further includes grid lines 332b, which are arranged around the hollows 332a, and can also be understood as the grid lines 332b being used to define the hollows 332a. The grid lines 332b can dissipate the heat generated in the surroundings, or guide the static electricity generated in the surroundings, thereby ensuring the reliability of the display module 10. Further, the sum of the coverage areas of the hollows 332a is greater than the coverage area of the grid lines 332b. The larger the coverage area of the hollows 332a, the larger the adhesion area of the adhesive structure 400 with the second supporting sub-section 220 through the hollows 332a, and the more stable the structure of the second supporting sub-section 220. Specifically, the larger sum of the coverage areas of the hollows 332a can be due to the larger number of hollows 332a in the second conductive sub-section 332, or the larger coverage area of each hollow 332a.
[0082] Continue to refer Figure 8 and Fig. 9 As shown, the first conductive section 331 and the second conductive section 332 are connected.
[0083] For further reference, Fig. 9 As shown, the first conductive sub-section 331 and the second conductive sub-section 332 can be connected and arranged to ensure the flatness and continuity of the overall structure. Exemplarily, for the preparation process of the conductive layer 330, the first conductive sub-section 331 and the second conductive sub-section 332 can be prepared at different positions, respectively, and the first conductive sub-section 331 and the second conductive sub-section 332 can be electrically connected. Further, considering that the first conductive sub-section 331 and the second conductive sub-section 332 are located at the same film layer position, and the first conductive sub-section 331 and the second conductive sub-section 332 are electrically connected, the first conductive sub-section 331 and the second conductive sub-section 332 can be an integrally formed structure, and the first conductive sub-section 331 and the second conductive sub-section 332 are prepared simultaneously, thereby reducing the process preparation cost of the display module 10.
[0084] Furthermore, by connecting the first conduction sub-portion 331 to the second conduction sub-portion 332, the heat and static electricity conducted at the second conduction sub-portion 332 can be transferred to the first conduction sub-portion 331, thereby ensuring the transmission effect of static electricity and heat in the display module 10. Figure 8As shown, the projection of the driver chip 100A along the first direction X1 overlaps with the second conduction division 332, or in other words, the distance between the driver chip 100A and the second conduction division 332 is smaller than the distance between the driver chip 100B and the first conduction division 331. Therefore, by connecting the first conduction division 331 and the second conduction division 332, the heat and static electricity generated by the driver chip 100A conducted by the second conduction division 332 can be further transmitted, ensuring the transmission effect of static electricity and heat, thereby avoiding the influence of temperature and static electricity on the display module 10, and ensuring the overall reliability of the display module 10.
[0085] Fig.10 It is a structural schematic diagram of the first adhesive structure provided by an embodiment of the present invention; the adhesive structure 400 includes an adhesive colloid 400a and thermally conductive particles 400b disposed in the adhesive colloid 400a; the thermal conductivity coefficient of the thermally conductive particles 400b is greater than the thermal conductivity coefficient of the adhesive colloid 400a.
[0086] Among them, reference Fig.10 As shown, the adhesive structure 400 includes an adhesive colloid 400a and thermally conductive particles 400b, wherein the thermally conductive particles 400b are disposed in the adhesive colloid 400a. The thermal conductivity of the thermally conductive particles 400b is greater than that of the adhesive colloid 400a. Therefore, the adhesive structure 400 can achieve heat transmission through the thermally conductive particles 400b, thereby achieving heat dissipation of the heat generated by the surrounding structure. Therefore, the adhesive structure 400 can ensure the stability of the display module 10 while also ensuring the reliability of the display module 10.
[0087] Fig.11 4 is a schematic diagram of a second adhesive structure provided by an embodiment of the present invention; the adhesive structure 400 includes an adhesive colloid 400c and conductive particles 400d disposed in the adhesive colloid 400c; the resistivity of the conductive particles 400d is less than the resistivity of the adhesive colloid 400c.
[0088] Among them, reference Fig.11 As shown, the adhesive structure 400 includes an adhesive colloid 400c and conductive particles 400d, and the conductive particles 400d are disposed in the adhesive colloid 400c. The resistivity of the conductive particles 400d is less than that of the adhesive colloid 400c, and the conductive particles 400d have good conductivity. Therefore, the adhesive structure 400 can realize the extraction of static electricity through the conductive particles 400d, and then realize the extraction of static electricity generated in the surrounding structure. Therefore, the adhesive structure 400 can ensure the stability of the display module 10 structure while also ensuring the reliability of the display module 10.

Fig.12 The second adhesive layer 340 of the support structure 300 is taken as an example. The support structure boundary 311 includes a first protruding portion 311a and a first recessed portion 311b, and the first protruding portion 311a and the first recessed portion 311b are arranged alternately. It can also be understood that there is a first recessed portion 311b between two adjacent first protruding portions 311a, and there is a first protruding portion 311a between two adjacent first recessed portions 311b. The support structure boundary 311 is an uneven boundary line.
[0091] For further reference, Fig.13 As shown, the adhesive structure 400 includes a first adhesive boundary 411, and the first adhesive boundary 411 is located at a boundary line on one side of the adhesive structure 400 away from the binding portion 100b. The first adhesive boundary 411 includes a second protruding portion 411a and a second recessed portion 411b, and the second protruding portion 411a and the second recessed portion 411b are alternately arranged, which can also be understood as a second recessed portion 411b existing between two adjacent second protruding portions 411a, and a second protruding portion 411a existing between two adjacent second recessed portions 411b, and the first adhesive boundary 411 is an uneven boundary line.
[0092] Specifically, refer to Figures 14 to 16As shown, the support structure boundary 311 and the first adhesive boundary 411 in the display module 10 are connected. Specifically, as shown in FIG14, the first adhesive boundary 411 includes a second protruding portion 411a and a second recessed portion 411b that are alternately arranged; the first protruding portion 311a and the second recessed portion 411b are connected, and the first recessed portion 311b is connected to the second protruding portion 411a. By staggered connection of the concave and convex boundary lines, the contact area between the support structure 300 and the adhesive structure 400 can be increased, thereby improving the fusion effect between the support structure 300 and the adhesive structure 400, thereby avoiding the peeling of the film layer at the junction of the support structure 300 and the adhesive structure 400, thereby ensuring the stability of the overall structure of the display module 10.
[0093] Optional, reference Figures 14 to 16 As shown, the first protrusion 311a, the first recess 311b, the second protrusion 411a and the second recess 411b have various shapes, such as triangle, rectangle or arc, so as to increase the diversity of the interface between the support structure 300 and the adhesive structure 400. Figures 14 to 16 Only three different shapes are shown, and the shape can be adaptively adjusted according to the requirements of the display module 10 .
[0094] Continue to refer Figure 2 As shown, along the second direction X2, the adhesion structure 400 includes a second adhesion boundary 421 close to the bending portion 100b, and the first support section 210 includes a support section boundary 211 close to the bending portion 100b; the distance between the orthographic projection of the second adhesion boundary 421 on the first support section 210 and the support section boundary 211 is L; wherein 0<L≤5mm.
[0095] Specifically, refer to Figure 2As shown, the adhesive structure 400 also includes a second adhesive boundary 421, and the second adhesive boundary 421 is located at a side boundary line of the adhesive structure close to the binding portion 100b. The first support subdivision 210 includes a support subdivision boundary 211, and the support subdivision boundary 211 is located at a side boundary line of the first support subdivision 210 close to the binding portion 100b. Among them, the distance between the positive projection of the second adhesive boundary 421 on the first support subdivision 210 and the support subdivision boundary 211 is L, and L satisfies: 0<L≤5mm, for example, L can be 0.8mm, 1mm, 3mm or 4.5mm, etc. It can be understood that the boundary of the adhesive structure 400 closest to the bending portion 100b is located in the area defined by the first support subdivision 210 and the second support subdivision 220, so the adhesive structure 400 is located in the defined area of the first support subdivision 210 and the second support subdivision 220 as a whole. Furthermore, the adhesive structure 400 is disposed within the display area of the first supporting section 210 and the second supporting section 220 , which ensures the overall structural stability of the display module 10 while also not affecting the normal bending of the bending portion 100 b , thereby ensuring the reliability of the display module 10 .
[0096] Fig.17 yes Figure 1 An enlarged schematic diagram of the E area, see Figure 1 , Figure 2 and Fig.17 As shown, the display portion 100a includes a display area 100a1 and a first fan-out area 100a2, and the first fan-out area 100a2 is located on a side of the display area 100a1 close to the bending portion 100b; along the first direction X1, the adhesive structure 400 overlaps with both the display area 100a1 and the first fan-out area 100a2.
[0097] Specifically, refer to Fig.17 As shown, the display portion 100a includes a display area 100a1 and a first fan-out area 100a2, wherein the first fan-out area 100a2 is located on a side of the display area 100a1 close to the bending portion 100b. The display area 100a1 is used to realize the display function of the display panel 10 as a whole, and the first fan-out area 100a2 is provided with some fan-out lines (not specifically shown in the figure) transmitted to the display area 100a1. Figure 2 As shown, the adhesive structure 400 can overlap with the display area 100a1 and the first fan-out wiring 100a2 along the first direction X1. By maximizing the setting space of the adhesive structure 400, it is beneficial to ensure the stability of the second supporting section 220 and avoid peeling of the second supporting section 220, thereby better ensuring the overall structural stability of the display module 10.
[0098] Optional, reference Fig.17As shown, the binding portion 100c may also include a second fan-out area 100c1, which is located on one side of the binding portion 100c close to the bending portion 100b. The fan-out arranged in the second fan-out area 100c2 can transmit the signal transmitted on the non-light-emitting side (such as the signal provided by the driver chip 100A or the flexible circuit board 100B), thereby ensuring the overall display function of the display module 10. Further, refer to Fig.17 As shown, the binding area 100c may further include a test area 100c2, an electrostatic transmission area 100c3, a lighting driving test area 100c4 and a binding area 100c5 which are sequentially away from the bending portion 100b, and the binding area 100c5 may be bound and electrically connected to the flexible circuit board 100B.

The packaging adhesive structure 500 is located on at least one side of the bending portion 100 b and contacts the bending portion 100 b .
[0100] The display module 10 further includes a packaging adhesive structure 500, and the packaging adhesive structure 500 is located on at least one side of the bent portion 100b.

By providing the encapsulation adhesive structure 500, the space on both sides of the bending portion 100b can be filled to ensure the stability of the overall structure of the display module 10, and the overall structure can also be protected to a certain extent. Further, the encapsulation adhesive structure 500 can have a certain viscosity, so as to ensure that the bending state of the bending portion 100b is more stable, thereby improving the overall structural stability of the display module 10.

[0102] For further reference, Fig. 20 As shown, the first encapsulation glue section 510 in the encapsulation glue structure 500 is located on the side of the bending portion 100b close to the support structure 300, and the adhesive structure 400 is located on the side of the support structure 300 close to the bending portion 100b. Both the adhesive structure 400 and the encapsulation glue structure 500 have a certain viscosity, so the area set for setting the adhesive structure 400 can be replaced by the first encapsulation glue section 510. However, it should be noted that the setting position of the adhesive structure 400 does not exceed the limited area of the first support section 210 and the second support section 220, and the first encapsulation glue section 510 can fill the entire area, so the overall occupied space of the first encapsulation glue section 510 is larger than the occupied space of the adhesive structure 400, so the first encapsulation glue section 510 is reused as at least part of the adhesive structure 400. By means of structural reuse, the overall process preparation cost of the display module 10 can also be reduced.
