Description

Technical Field

[0001] This application relates to the field of display technology, and more particularly to a display module and display device. Background Technology

To meet the bending requirements of foldable screens, most components are made of flexible materials. Compared to flexible display panels, the mid-frame and folding hinge of the device provide greater impact resistance. However, in the overall structure, holes need to be cut into the support material at the locations of the camera and photosensitive devices to meet optical requirements; some products add transparent pads below the photosensitive holes to improve impact resistance, but the improvement is minimal.

[0010] In one embodiment, the light-transmitting pad and the light-transmitting support sheet are made of different materials, and the light-transmitting pad and the light-transmitting support sheet are separately disposed;

[0011] The material of the light-transmitting pad includes at least one of foam, silicone gel, and non-Newtonian fluid buffer material.

[0012] In one embodiment, the light-transmitting pad includes at least a first sub-part, which protrudes from one side of the light-transmitting support sheet and is inserted into the through hole;

[0013] The first sub-part is made of the same material as the light-transmitting support sheet, and the first sub-part and the light-transmitting support sheet are integrally formed.

[0019] In one embodiment, the display module further includes a cover plate and a first adhesive layer. The cover plate is disposed on the display side of the display panel, and the first adhesive layer is disposed between the cover plate and the display panel and connects the cover plate and the display panel.

[0020] The display module further includes a first rubber ring, which is disposed on the side of the light-transmitting support sheet facing the back plate and is arranged around the periphery of the light-transmitting pad.

Furthermore, the elastic modulus of the light-transmitting support sheet is greater than or equal to the elastic modulus of the light-transmitting pad. In other words, under the same impact, the deformation of the light-transmitting support sheet is the same as or greater than that of the light-transmitting pad. Therefore, while supporting the light-transmitting pad, the light-transmitting support sheet can also absorb the impact force through its own deformation, further reducing the stress on the display panel at the corresponding through-hole location, thereby improving the impact resistance of the display panel.

[0033] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0034] This application provides a display module 100 and a display device. These will be described in detail below. It should be noted that the order of description of the following embodiments is not intended to limit the preferred order of the embodiments.

[0035] This application does not impose specific limitations on the structure of the display module 100. In one embodiment, the display panel 1 can be configured as a full-screen structure. Correspondingly, the photosensitive area 12 adopts under-display camera technology. The display panel 1 has a display area 11 and a photosensitive area 12 located within the display area 11. Both the display area 11 and the photosensitive area 12 can be displayed normally. The shape of the photosensitive area 12 includes, but is not limited to, one of the following: circular, U-shaped, teardrop-shaped, or rectangular. The photosensitive area 12 is the under-display camera area, and a photosensitive device can be disposed at the position corresponding to the photosensitive area 12.

[0036] Please see Figure 1 and Figure 6 , Figure 1 This is a schematic diagram of the film layers of the display module 100 provided in the embodiments of this application. Figure 6 This is a plan view of the display module 100 provided in the embodiment of this application; the display module 100 includes a display panel 1, a back plate 2, and a spacer structure 3. The under-display 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 arranged opposite to each other. 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. The display panel 1 is provided with a photosensitive device (not shown in the figure) at the position corresponding to the photosensitive area 12.

[0037] The back plate 2 is disposed on the back side B. The back plate 2 typically includes a buffer layer 21 and a support layer 22. The buffer layer 21 is disposed on the back side B of the display panel 1, and the support layer 22 is disposed 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, a through hole 23 needs to be provided on the back plate 2 at the position corresponding to the photosensitive device. The through hole 23 penetrates 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 pad 31 is usually added inside the photosensitive hole. However, the light-transmitting pad 31 is a single unit with a fixed and uniform elastic modulus. Therefore, when applied to actual products, the setting of this light-transmitting pad 31 has a poor effect on improving the impact resistance of the display panel 1.

[0039] However, in the embodiments provided in this application, the spacer structure 3 includes a light-transmitting pad 31 and a light-transmitting support piece 32. When the display module 100 is impacted, the light-transmitting pad 31, inserted into the through hole 23, can support the display panel 1, preventing the display panel 1 from undergoing large deformation at the position corresponding to the through hole 23. At the same time, when the display module 100 is impacted, the light-transmitting support piece 32, disposed on the back side of the display panel 1, provides support for the light-transmitting pad 31, thereby decomposing the display module 1 together with the light-transmitting pad 31. The stress on the display panel 1 at the corresponding through hole 23 position; and the elastic modulus of the light-transmitting support sheet 32 ​​is greater than or equal to the elastic modulus of the light-transmitting pad 31. That is to say, under the same impact, the deformation of the light-transmitting support sheet 32 ​​is the same as or greater than that of the light-transmitting pad 31. Therefore, while supporting the light-transmitting pad 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 corresponding through hole 23 position, thereby improving the impact resistance of the display panel 1.

[0040] This application does not impose specific limitations on the ratio of the elastic modulus of the light-transmitting pad 31 and the light-transmitting support sheet 32. In one embodiment, the ratio of the elastic modulus E2 of the light-transmitting pad 31 to the elastic modulus E1 of the light-transmitting support sheet 32 ​​is set to...

[0041] It is known that when subjected to impact, the smaller the elastic modulus E1 of the light-transmitting support sheet 32, the greater the deformation of the light-transmitting support sheet 32, and the more impact energy it can absorb. However, if the elastic modulus E1 of the light-transmitting support sheet 32 ​​is too small, the support of the light-transmitting support sheet 32 ​​for the light-transmitting pad 31 will be insufficient. The ratio of the elastic modulus E2 of the light-transmitting pad 31 to the elastic modulus E1 of the light-transmitting support sheet 32 ​​is set to... Thus, when subjected to impact, the light-transmitting support sheet 32 ​​can deform and absorb the impact energy; at the same time, the light-transmitting support sheet 32 ​​can provide sufficient support for the light-transmitting pad 31, so that the light-transmitting pad 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] Meanwhile, this application does not impose specific limitations on the elastic modulus of the light-transmitting pad 31 and the light-transmitting support sheet 32.

[0043] In the prior art, the elastic modulus of the light-transmitting pad 31 is typically set to 8-9 GPa. In some embodiments, the elastic modulus of the light-transmitting pad 31 and the light-transmitting support sheet 32 ​​are simultaneously increased to 1-2 times that of the existing pads, and the elastic modulus of the light-transmitting pad 31 and the light-transmitting support sheet 32 ​​are the same. Furthermore, when the display module 100 is subjected to impact, the light-transmitting pad 31 and the light-transmitting support sheet 32 ​​can jointly support the display panel 1, jointly decompose the stress on the display panel 1 at the position corresponding to the through hole 23, reduce 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 to existing gaskets, the elastic modulus E2 of the light-transmitting gasket 31 is increased to 2-3 times, and the elastic modulus E1 of the light-transmitting support sheet 32 ​​is increased to 1-2 times. That is, the elastic modulus E2 of the light-transmitting gasket 31 can be greater than the elastic modulus E1 of the light-transmitting support sheet 32. In this embodiment, when the display module 100 is impacted, the light-transmitting gasket 31 with a larger elastic modulus provides rigid support to the display panel 1, reducing the deformation of the display panel 1 at the location corresponding to the through hole 23. Simultaneously, the light-transmitting support sheet 32 ​​provides flexible support to the light-transmitting gasket 31. When receiving impact force transmitted from the light-transmitting gasket 31, the light-transmitting support sheet 32 ​​can absorb the impact force through deformation. This not only decomposes the stress on the display panel 1 at the location corresponding to the through hole 23 but also prevents the gasket structure 3 from breaking due to excessively large overall elastic modulus.

[0045] In one embodiment, the elastic modulus E1 of the light-transmitting support sheet 32 ​​is set to 5 GPa ≤ E1 ≤ 15 GPa; and the elastic modulus E2 of the light-transmitting pad 31 is set to 10 GPa ≤ E2 ≤ 30 GPa.

[0046] This application does not impose specific limitations on the structure of the diaphragm structure 3.

[0047] Please see Figure 2 , Figure 2 This is a schematic diagram of a first structure of the spacer structure 3 provided in an embodiment of this application. In the first embodiment of this application, the light-transmitting pad 31 includes at least a first sub-part 311, which protrudes from one side of the light-transmitting support sheet 32 ​​and is inserted into the through hole 23; wherein, the first sub-part 311 and the light-transmitting support sheet 32 ​​are made of the same material and are integrally formed with each other.

[0048] In the first embodiment, the spacer structure 3 includes an integrally formed first sub-part 311 and a light-transmitting support sheet 32. In this case, only the first sub-part 311 is inserted into the through hole 23, and the thickness of the first sub-part 311 can be set much greater than the thickness of the light-transmitting support sheet 32. When the display module 100 is impacted, the first sub-part 311 supports the display panel 1, reducing the deformation of the display panel 1 at the location corresponding to the through hole 23. Simultaneously, the light-transmitting support sheet 32 ​​provides flexible support for the first sub-part 311. When receiving impact force transmitted from the first sub-part 311, the light-transmitting support sheet 32 ​​can absorb the impact force through deformation, thus decomposing the stress on the display panel 1 at the location corresponding to the through hole 23 and preventing the spacer structure 3 from breaking due to excessive overall elastic modulus.

[0049] Please see Figure 3 , Figure 3 This is a schematic diagram of a second structure of the spacer structure 3 provided in an embodiment of this application. In the second embodiment of this application, the light-transmitting pad 31 further includes a second sub-part 312 inserted into the through hole 23. The second sub-part 312 is disposed on the side of the first sub-part 311 opposite to the light-transmitting support sheet 32. The second sub-part 312 is made of a different material than the first sub-part 311. The material of the second sub-part 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 a second sub-part 312 is inserted into the through hole 23; at this time, compared with the first embodiment, the thickness of the first sub-part 311 can be set to be smaller to prevent the light-transmitting pad 31 from hitting the display panel 1; at the same time, the second sub-part 312 is disposed on the side of the first sub-part 311 away from the light-transmitting support sheet 32, and the material of the second sub-part 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-part 311 supports the second sub-part 312, thereby supporting the display panel 1 and 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-part 311. When receiving the impact force transmitted from the first sub-part 311, the light-transmitting support sheet 32 ​​can absorb the impact force through deformation. On the one hand, it can decompose the stress on the display panel 1 at the position corresponding to the through hole 23; on the other hand, it can prevent the spacer structure 3 from breaking due to excessive overall elastic modulus.

[0052] Furthermore, when the display module 100 is subjected to a large impact, the second sub-part 312 disposed on the first sub-part 311 can, on the one hand, 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. Moreover, the second sub-part 312 is more flexible than the first sub-part 311, and there is no risk of damaging the display panel 1 during contact with it, thereby improving the quality of the display assembly. On the other hand, the second sub-part 312 can absorb the impact force transmitted from the display panel 1. The second sub-part 312, together with the first sub-part 311 and the light-transmitting support sheet 32, decomposes the stress on the display panel 1 at the position corresponding to the through hole 23, further improving the impact resistance of the display panel 1.

[0053] Please see Figure 4 , Figure 4 This is a schematic diagram of a third structure of the spacer structure 3 provided in the embodiments of this application. In the third embodiment of this application, the light-transmitting pad 31 and the light-transmitting support sheet 32 ​​are made of different materials, and the light-transmitting pad 31 and the light-transmitting support sheet 32 ​​are separately arranged; wherein, the material of the light-transmitting pad 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 light-transmitting pad 31 and the light-transmitting support sheet 32 ​​are made of different materials, and the material of the light-transmitting pad 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-part 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. Furthermore, the second sub-part 312 has a certain degree of flexibility, so there is no risk of damaging the display panel 1 during contact with it, thereby improving the quality of the display assembly. On the other hand, the second sub-part 312 can absorb the impact force transmitted from the display panel 1. The second sub-part 312 and the light-transmitting support sheet 32 ​​jointly decompose the stress on the display panel 1 at the position corresponding to the through hole 23, further improving the impact resistance of the display panel 1.

[0056] Based on the second and third embodiments, the light-transmitting pad 31 or the second sub-part 312 is made of a different material than the light-transmitting support sheet 32; this application does not impose specific limitations on the material of the second sub-part 312 or the light-transmitting pad 31. It is acceptable as long as the elastic modulus requirement is met and the material transmittance is ≥90%.

[0057] Based on the second embodiment, "the light-transmitting pad 31 includes a first sub-part 311 and a second sub-part 312", please refer to [link / reference needed]. Figure 3 The light-transmitting pad 31 further includes a second adhesive layer 313, which is disposed between the first sub-part 311 and the second sub-part 312, and connects the first sub-part 311 and the second sub-part 312.

[0058] Continuing with the previous embodiment, the light-transmitting pad 31 is inserted into the through hole 23 to support the display panel 1 when it deforms. To prevent the light-transmitting pad 31 from damaging the display panel 1 by passing through the through hole 23 during the bonding process, the depth of the through hole 23 is set to T1, and the thickness of the portion of the light-transmitting pad 31 located within the through hole 23 is set to T2, wherein T2 is less than T1. Preferably, in one embodiment, T2 = 0.95T1; with this configuration, when the display module 100 is subjected to impact, the display panel 1 can contact the light-transmitting pad 31 with minimal deformation, thereby reducing the deformation of the display panel 1 at the position corresponding to the through hole 23.

[0059] Based on the first and second embodiments, the light-transmitting pad 31 or the first sub-part 311 is made of the same material as the light-transmitting support sheet 32. This application does not specify the material of the light-transmitting support sheet 32, as long as it meets the requirements for elastic modulus and light transmittance. The light 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 plexiglass, special plastics, composite materials containing nanoparticle fillers, and transparent silicone rubber.

[0060] It is 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 provided, the light-transmitting support sheet 32 ​​covers the periphery of the through hole 23. In order to further distribute the impact force received by the display panel 1 at the position corresponding to the periphery of the through hole 23, the overlap 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. Without affecting the overall space, the radius of the through hole 23 is set to R1, and the radius of the light-transmitting support sheet 32 ​​is set to R2, wherein... The light-transmitting support sheet 32 ​​has sufficient overlap with the periphery of the through hole 23, thereby absorbing more impact energy and reducing the impact force on the display panel 1 at the position corresponding to the periphery of the through hole 23.

[0061] As mentioned above, since the light-transmitting pad 31 is inserted into the through hole 23, the size of the light-transmitting pad 31 must be smaller than the size of the through hole 23. However, when the size of the light-transmitting pad 31 is too small, the size difference between the light-transmitting pad 31 and the light-transmitting support piece 32 is large. This large size difference causes stress concentration at the connection between the light-transmitting pad 31 and the light-transmitting support piece 32. When the display module 100 is subjected to a large impact, the light-transmitting pad 31 and the light-transmitting support piece 32 are prone to breakage at their connection. In one embodiment, the radius of the light-transmitting pad 31 is set to R3, where... In this way, not only can the light-transmitting pad 31 be inserted into the through hole 23, but the size difference between the light-transmitting support 32 and the light-transmitting pad 31 can also be reduced, thereby improving the stress concentration at the connection between the light-transmitting support 32 and the light-transmitting pad 31.

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

[0063] Please refer to the above examples. Figure 5 , Figure 5 This is a simulated bar graph of the display panel 1 provided in an embodiment of this application. In the prior art, a light-transmitting pad 31 is added inside the photosensitive hole. The elastic modulus of the light-transmitting pad 31 is usually set to 8-9 GPa. After adding this light-transmitting pad 31, the strain value ε1 of the display panel 1 is 0.3858%. In the embodiment where "the light-transmitting pad 31 includes a first sub-part 311", after setting the spacer structure 3, the strain value ε2 of the display panel 1 is 0.383%. In the embodiment where "the light-transmitting pad 31 includes a first sub-part 311 and a second sub-part 312", after setting the spacer structure 3, the strain value ε3 of the display panel 1 is 0.371%. In the embodiment where "the radius of the through hole 23 is set to R1, the radius of the light-transmitting support sheet 32 ​​is set to R2, and the radius of the light-transmitting pad 31 is set to R3, wherein..." In one embodiment, after the spacer structure 3 is provided, the strain value ε4 of the display panel 1 is 0.325%.

[0064] As can be seen from the above, the spacer structure 3 is configured such that "the light-transmitting pad 31 includes a first sub-part 311 and a second sub-part 312", and the dimensions of the light-transmitting support sheet 32 ​​and the light-transmitting pad 31 are set simultaneously, 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 back panel 2 includes a buffer layer 21 and a support layer 22 stacked together. The buffer layer 21 is disposed on the back side of the display panel 1, and the support layer 22 is disposed on the side of the buffer layer 21 opposite to the display panel 1.

[0066] In one embodiment, please refer to Figure 1 The display module 100 further includes a cover plate 5 and a first adhesive layer 6. The cover plate 5 is disposed on the display side A of the display panel 1, and the first adhesive layer 6 is disposed 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 adhesive ring 4, which is disposed on the side of the light-transmitting support sheet 32 ​​facing the back plate 2 and surrounds the periphery of the light-transmitting pad 31. The light-transmitting support sheet 32 ​​is connected to the back plate 2 through the first adhesive ring 4, and the elastic modulus of the first adhesive ring 4 is greater than the elastic modulus of the first adhesive layer 6.

[0067] In other words, the light-transmitting support sheet 32 ​​is connected to the back plate 2 through the first rubber ring 4; by selecting the first rubber ring 4 with a large elastic modulus, when the display module 100 is impacted, the first rubber ring 4 can absorb and decompose the impact force through its own deformation, thereby reducing the deformation of the light-transmitting pad 31 and thus preventing the light-transmitting pad 31 from breaking due to a large impact.

[0068] This application does not impose specific limitations on the elastic modulus E3 of the first rubber ring 4. To ensure the cushioning effect, the elastic modulus E3 of the first rubber ring 4 is greater than 1 GPa.
