[0033] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0034] The embodiments of the present application provide a display module 100 and a display device. The following are detailed descriptions of each. It should be noted that the description order of the following embodiments is not intended to limit the preferred order of the embodiments.

[0035] The present application does not specifically limit the structure of the display module 100. In one embodiment, the display panel 1 can be set to a full-screen structure; correspondingly, the photosensitive area 12 adopts the under-screen camera technology, and the display panel 1 has a display area 11 and a photosensitive area 12 located in the display area 11. Both the display area 11 and the photosensitive area 12 can display normally, and the shape of the photosensitive area 12 includes but is not limited to one of a circle, a U-shape, a water drop shape or a rectangle. The photosensitive area 12 is the under-screen camera area, and a photosensitive device can be set at the position corresponding to the photosensitive area 12.

[0036] See also Figure 1 and Figure 6 , Figure 1 Schematic diagram of the film layer of the display module 100 provided in the embodiment of the present application, Figure 6 A plan schematic diagram of a display module 100 provided for an embodiment of the present application; the display module 100 includes a display panel 1, a back panel 2 and a spacer structure 3, and the under-screen camera technology of the display panel 1 adopts a blind hole structure; that is, the display panel 1 includes a display side A and a back side B that are relatively arranged, and on the display side A of the display panel 1, the display panel 1 has a display area 11, and a photosensitive area 12 located in the display area 11, and the display panel 1 is provided with a photosensitive device (not shown in the figure) at a position corresponding to the photosensitive area 12.

[0037] The back plate 2 is arranged on the back side B, and usually the back plate 2 includes a buffer layer 21 and a support layer 22. The buffer layer 21 is arranged on the back side B of the display panel 1, and the support layer 22 is arranged on the side of the buffer layer 21 away from the display panel 1. Since the buffer layer 21 and the support layer 22 are opaque, it is necessary to set the through hole 23 on the back plate 2 at the position corresponding to the photosensitive device. The through hole 23 passes through the back plate 2, so that the photosensitive device can sense light from the through hole 23.

[0038] It should be noted that, in the prior art, in order to improve the impact resistance of the display panel 1 at the position corresponding to the photosensitive hole, a light-transmitting gasket 31 is usually added inside the photosensitive hole. However, the elastic modulus of the single light-transmitting gasket 31 is fixed and single. Therefore, when applied to actual products, the setting of such a light-transmitting gasket 31 has a poor effect on improving the impact resistance of the display panel 1.

[0039] However, in the embodiment provided in the present application, the spacer structure 3 includes a light-transmitting gasket 31 and a light-transmitting support sheet 32. When the display module 100 is impacted, the light-transmitting gasket 31 inserted in the through hole 23 can support the display panel 1 to prevent the display panel 1 from being greatly deformed at the position corresponding to the through hole 23. At the same time, when the display module 100 is impacted, the light-transmitting support sheet 32 ​​arranged on the back side of the display panel 1 provides support for the light-transmitting gasket 31, thereby decomposing the light-transmitting gasket 31 together with the light-transmitting gasket 31. The display panel 1 is subjected to stress at the position corresponding to the through hole 23; and the elastic modulus of the light-transmitting support sheet 32 ​​is greater than or equal to the elastic modulus of the light-transmitting gasket 31, that is, under the same impact, the deformation of the light-transmitting support sheet 32 ​​is the same as that of the light-transmitting gasket 31, or greater than the deformation of the light-transmitting gasket 31. Therefore, while supporting the light-transmitting gasket 31, the light-transmitting support sheet 32 ​​can also absorb the impact force through its own deformation, further reducing the stress on the display panel 1 at the position corresponding to the through hole 23, thereby improving the impact resistance of the display panel 1.

[0040] The present application does not impose any specific restrictions on the elastic modulus ratio of the light-transmitting spacer 31 and the light-transmitting support sheet 32. In one embodiment, the elastic modulus E of the light-transmitting spacer 31 is 2 The elastic modulus E of the transparent support sheet 32 1 The ratio is set to

[0041] It can be known that when subjected to impact force, the elastic modulus E of the transparent support sheet 32 1The smaller the value, the greater the deformation of the transparent support sheet 32, and the more impact energy can be absorbed; however, the elastic modulus E of the transparent support sheet 32 ​​is 1 If the elastic modulus E of the light-transmitting spacer 31 is too small, the light-transmitting support sheet 32 ​​will not be able to support the light-transmitting spacer 31 sufficiently. 2 The elastic modulus E of the transparent support sheet 32 1 The ratio is set to In this way, when subjected to impact force, the light-transmitting support sheet 32 ​​can be deformed to absorb the impact energy; at the same time, the light-transmitting support sheet 32 ​​can provide sufficient support for the light-transmitting gasket 31, so that the light-transmitting gasket 31 can stably support the display panel 1, thereby reducing the deformation of the display panel 1 at the position corresponding to the through hole 23, thereby improving the impact resistance of the display panel 1.

[0042] At the same time, the present application does not impose any specific limitation on the elastic modulus of the light-transmitting gasket 31 and the light-transmitting supporting sheet 32 ​​.

[0043] In the prior art, the elastic modulus of the light-transmitting gasket 31 is generally set to 8 to 9 GPa; in some embodiments, the elastic modulus of the light-transmitting gasket 31 and the light-transmitting supporting sheet 32 ​​are simultaneously increased to 1 to 2 times of the existing gaskets, and the elastic modulus of the light-transmitting gasket 31 and the light-transmitting supporting sheet 32 ​​are the same; and, when the display module 100 is impacted, the light-transmitting gasket 31 and the light-transmitting supporting sheet 32 ​​can jointly support the display panel 1, and jointly decompose the stress of the display panel 1 at the position corresponding to the through hole 23, thereby reducing the deformation of the display panel 1 at the position corresponding to the through hole 23, thereby improving the impact resistance of the display panel 1.

[0044] In another embodiment, compared with the existing gasket, the elastic modulus E of the light-transmitting gasket 31 is 2 The elastic modulus E of the transparent support sheet 32 ​​is increased to 2 to 3 times of the existing one. 1 The elastic modulus E of the light-transmitting gasket 31 is increased to 1 to 2 times of the existing one. 2 The elastic modulus E of the transparent support sheet 32 ​​may be greater than 1In this embodiment, when the display module 100 is impacted, the light-transmitting gasket 31 with a larger elastic modulus provides rigid support for the display panel 1, which can reduce the deformation of the display panel 1 at the position corresponding to the through hole 23; at the same time, the light-transmitting support sheet 32 ​​provides flexible support for the light-transmitting gasket 31. When receiving the impact force transmitted from the light-transmitting gasket 31, the light-transmitting support sheet 32 ​​can absorb the impact force by deformation, which can decompose the stress of the display panel 1 at the position corresponding to the through hole 23 on the one hand; on the other hand, it can prevent the gasket structure 3 from being broken due to the excessive overall elastic modulus.

[0045] In one embodiment, the elastic modulus E of the light-transmitting support sheet 32 ​​is 1 Set to 5Gpa≤E 1 ≤15Gpa; the elastic modulus E of the light-transmitting gasket 31 2 Set to 10Gpa≤E 2 ≤30Gpa.

[0046] The present application does not impose any specific limitation on the structure of the spacer structure 3 .

[0047] See also Figure 2 , Figure 2 A schematic diagram of the first structure of the spacer structure 3 provided in the embodiment of the present application. In the first embodiment of the present application, the light-transmitting spacer 31 at least includes a first sub-portion 311, the first sub-portion 311 is protruding from one side of the light-transmitting support sheet 32, and is inserted into the through hole 23; wherein the first sub-portion 311 and the light-transmitting support sheet 32 ​​are made of the same material, and the first sub-portion 311 and the light-transmitting support sheet 32 ​​are integrally arranged.

[0048] In the first embodiment, the spacer structure 3 includes the first sub-portion 311 and the light-transmitting support sheet 32 ​​which are integrally formed. At this time, only the first sub-portion 311 is inserted into the through hole 23, and the thickness of the first sub-portion 311 can be set to be much greater than the thickness of the light-transmitting support sheet 32; when the display module 100 is impacted, the first sub-portion 311 supports the display panel 1, which can reduce the deformation of the display panel 1 at the position corresponding to the through hole 23; at the same time, the light-transmitting support sheet 32 ​​provides flexible support for the first sub-portion 311, and when receiving the impact force transmitted from the first sub-portion 311, the light-transmitting support sheet 32 ​​can absorb the impact force by deformation, which can decompose the stress of the display panel 1 at the position corresponding to the through hole 23 on the one hand; on the other hand, it can prevent the spacer structure 3 from breaking due to the excessive overall elastic modulus.

[0049] See also Figure 3 , Figure 3A second structural schematic diagram of the spacer structure 3 provided in an embodiment of the present application. In the second embodiment of the present application, the light-transmitting gasket 31 further includes a second sub-portion 312 inserted into the through hole 23, and the second sub-portion 312 is arranged on a side of the first sub-portion 311 away from the light-transmitting support sheet 32; wherein the material of the second sub-portion 312 is different from that of the first sub-portion 311, and the material of the second sub-portion 312 includes one of foam, silicone gel and non-Newtonian fluid buffer material.

[0050] In the second embodiment, the difference from the first embodiment is that the second sub-portion 312 is also inserted into the through hole 23; at this time, compared with the first embodiment, the thickness of the first sub-portion 311 can be set to be smaller to avoid the light-transmitting gasket 31 from pressing against the display panel 1; at the same time, the second sub-portion 312 is arranged on the side of the first sub-portion 311 away from the light-transmitting support sheet 32, and the material of the second sub-portion 312 includes at least one of foam, silicone gel and non-Newtonian fluid buffer material.

[0051] When the display module 100 is impacted, the first sub-portion 311 supports the second sub-portion 312, thereby supporting the display panel 1, and further reducing the deformation of the display panel 1 at the position corresponding to the through hole 23; at the same time, the light-transmitting support sheet 32 ​​provides flexible support for the first sub-portion 311. When receiving the impact force transmitted from the first sub-portion 311, the light-transmitting support sheet 32 ​​can absorb the impact force by deformation, which can decompose the stress of the display panel 1 at the position corresponding to the through hole 23 on the one hand; on the other hand, it can prevent the gasket structure 3 from breaking due to the excessive overall elastic modulus.

[0052] Furthermore, when the display module 100 is subjected to a large impact, the second sub-portion 312 arranged on the first sub-portion 311, on the one hand, can provide support for the display panel 1, thereby reducing the deformation of the display panel 1 at the position corresponding to the through hole 23, and the second sub-portion 312 is more flexible than the first sub-portion 311, and there is no risk of damaging the display panel 1 during the contact with the display panel 1, thereby improving the quality of the display component; on the other hand, the second sub-portion 312 can absorb the impact force transmitted from the display panel 1, and the second sub-portion 312, the first sub-portion 311 and the light-transmitting supporting sheet 32 ​​together decompose the stress on the display panel 1 at the position corresponding to the through hole 23, thereby further improving the impact resistance of the display panel 1.

[0053] See also Figure 4 , Figure 4A third structural schematic diagram of the spacer structure 3 provided in an embodiment of the present application. In the third embodiment of the present application, the light-transmitting gasket 31 and the light-transmitting support sheet 32 ​​are made of different materials, and the light-transmitting gasket 31 and the light-transmitting support sheet 32 ​​are separately arranged; wherein the material of the light-transmitting gasket 31 includes at least one of foam, silicone gel and non-Newtonian fluid buffer material.

[0054] In the third embodiment, the difference from the first embodiment is that the material of the light-transmitting gasket 31 and the light-transmitting supporting sheet 32 ​​are different, and the material of the light-transmitting gasket 31 includes one of foam, silicone gel and non-Newtonian fluid buffer material.

[0055] When the display module 100 is subjected to a large impact, on the one hand, the second sub-portion 312 can provide support for the display panel 1, thereby reducing the deformation of the display panel 1 at the position corresponding to the through hole 23, and the second sub-portion 312 has a certain flexibility. In the process of contacting with the display panel 1, there is no risk of damaging the display panel 1, thereby improving the quality of the display component; on the other hand, the second sub-portion 312 can absorb the impact force transmitted from the display panel 1, and the second sub-portion 312 and the light-transmitting supporting sheet 32 ​​jointly decompose the stress exerted on the display panel 1 at the position corresponding to the through hole 23, thereby further improving the impact resistance of the display panel 1.

[0056] Based on the second and third embodiments, the material of the light-transmitting gasket 31 or the second sub-section 312 is different from that of the light-transmitting supporting sheet 32; the present application does not impose any specific restrictions on the material of the second sub-section 312 or the light-transmitting gasket 31. As long as the elastic modulus requirements are met and the material transmittance is ≥ 90%, it will be fine.

[0057] Based on the second embodiment “the light-transmitting gasket 31 includes a first sub-portion 311 and a second sub-portion 312 ”, please refer to Figure 3 The light-transmitting gasket 31 further includes a second adhesive layer 313 , which is disposed between the first sub-portion 311 and the second sub-portion 312 , and the second adhesive layer 313 connects the first sub-portion 311 and the second sub-portion 312 .

[0058] Based on the above embodiment, the light-transmitting gasket 31 is inserted into the through hole 23 to support the display panel 1 when the display panel 1 is deformed. In order to prevent the light-transmitting gasket 31 from passing through the through hole 23 and damaging the display panel 1 during the bonding process, the depth of the through hole 23 is set to T 1 The thickness of the portion of the light-transmitting gasket 31 located in the through hole 23 is set to T 2 , where T 2 Less than T1 Preferably, in one embodiment, T 2 =0.95T 1 With such arrangement, when the display module 100 is impacted, the display panel 1 can come into contact with the light-transmitting gasket 31 with minimal deformation, thereby reducing the deformation amount of the display panel 1 at the position corresponding to the through hole 23.

[0059] Based on the first embodiment and the second embodiment, the material of the light-transmitting gasket 31 or the first sub-section 311 is the same as that of the light-transmitting support sheet 32. The present application does not make specific requirements on the material of the light-transmitting support sheet 32, as long as it can meet the elastic modulus requirements and the transmittance requirements. The transmittance of the light-transmitting support sheet 32 ​​is ≥95%. In one embodiment, the material of the light-transmitting support sheet 32 ​​includes one of modified organic glass, special plastics or composite materials filled with nanoparticles, and transparent silicone rubber.

[0060] It can be known that, under normal circumstances, when the display module 100 is subjected to a large impact, the display panel 1 is most likely to fail at the position corresponding to the periphery of the through hole 23; when the spacer structure 3 is set, the light-transmitting support sheet 32 ​​is covered at the periphery of the through hole 23. In order to further decompose the impact force received by the display panel 1 at the position corresponding to the periphery of the through hole 23, the overlapping area between the light-transmitting support sheet 32 ​​and the periphery of the through hole 23 can be increased. Taking "the through hole 23 is set as a circular hole" as an example, this application does not impose specific restrictions on the size of the light-transmitting support sheet 32. On the basis of not affecting the space of the entire machine, the radius of the through hole 23 is set to R 1 The radius of the light-transmitting support sheet 32 ​​is set to R 2 ,in, The transparent support sheet 32 ​​and the periphery of the through hole 23 have a sufficient overlapping area, so as to absorb more impact energy, thereby reducing the impact force received by the display panel 1 at the position corresponding to the periphery of the through hole 23 .

[0061] As mentioned above, since the light-transmitting gasket 31 is inserted into the through hole 23, the size of the light-transmitting gasket 31 is smaller than the size of the through hole 23. However, when the size of the light-transmitting gasket 31 is too small, the size difference between the light-transmitting gasket 31 and the light-transmitting support sheet 32 ​​is large, and the large size difference causes stress concentration at the connection between the light-transmitting gasket 31 and the light-transmitting support sheet 32. When the display module 100 is subjected to a large impact, the light-transmitting gasket 31 and the light-transmitting support sheet 32 ​​are prone to breakage at their connection. In one embodiment, the radius of the light-transmitting gasket 31 is set to R 3 ,in, In this way, not only can the light-transmitting gasket 31 be inserted into the through hole 23 , but also the size difference between the light-transmitting supporting sheet 32 ​​and the light-transmitting gasket 31 can be reduced, thereby improving the stress concentration at the connection between the light-transmitting supporting sheet 32 ​​and the light-transmitting gasket 31 .

[0062] It should be noted that the above-mentioned embodiment of “the size setting of the light-transmitting support sheet 32 ​​and the light-transmitting spacer 31 ” can be combined with any one of the first embodiment, the second embodiment and the third embodiment.

[0063] For the above example, please refer to Figure 5 , Figure 5 This is a simulated bar graph of the display panel 1 provided in the embodiment of the present application. In the prior art, a light-transmitting gasket 31 is added in the photosensitive hole, and the elastic modulus of the light-transmitting gasket 31 is usually set to 8-9 GPa. After adding such a light-transmitting gasket 31, the strain value ε of the display panel 1 is 1 is 0.3858%; in the embodiment of "the light-transmitting spacer 31 includes a first sub-portion 311", after the spacer structure 3 is provided, the strain value ε of the display panel 1 2 is 0.383%; in the embodiment of "the light-transmitting spacer 31 includes a first sub-portion 311 and a second sub-portion 312", after the spacer structure 3 is provided, the strain value ε of the display panel 1 3 is 0.371%; in "the radius of the through hole 23 is set to R 1 The radius of the light-transmitting support sheet 32 ​​is set to R 2 , the radius of the light-transmitting spacer 31 is set to R 3 ,in, In the embodiment, after the spacer structure 3 is provided, the strain value ε of the display panel 1 is 4 It is 0.325%.

[0064] From the above, it can be seen that the spacer structure 3 is set as "the light-transmitting gasket 31 includes a first sub-portion 311 and a second sub-portion 312", and the sizes of the light-transmitting supporting sheet 32 ​​and the light-transmitting gasket 31 are set at the same time, which can significantly reduce the strain value of the display panel 1, thereby improving the impact resistance of the display panel 1.

[0065] In one embodiment, the backplane 2 includes a buffer layer 21 and a support layer 22 which are stacked, the buffer layer 21 is disposed on the back side of the display panel 1 , and the support layer 22 is disposed on a side of the buffer layer 21 away from the display panel 1 .

[0066] In one embodiment, see Figure 1The display module 100 also includes a cover plate 5 and a first adhesive layer 6, wherein the cover plate 5 is arranged on the display side A of the display panel 1, and the first adhesive layer 6 is arranged between the cover plate 5 and the display panel 1, and connects the cover plate 5 and the display panel 1; the display module 100 also includes a first rubber ring 4, wherein the first rubber ring 4 is arranged on the side of the transparent support sheet 32 ​​facing the back plate 2, and the first rubber ring 4 is arranged around the periphery of the transparent gasket 31; wherein the transparent support sheet 32 ​​is connected to the back plate 2 through the first rubber ring 4, and the elastic modulus of the first rubber ring 4 is greater than the elastic modulus of the first adhesive layer 6.
