[0002] In recent years, the mobile phone screen shape of full screen, ultra-thin and narrow frame is favored by consumers, and the under-screen fingerprint technology gradually leads the market due to its effective improvement of screen ratio, weight reduction and good interaction function. The commonly used under-screen fingerprint technology is optical fingerprint identification technology, the mechanism of which is that the finger presses the fingerprint hole area, the light passes through the texture (ridge line and valley line) of the fingerprint, reflects different light, and is received by the sensor under the screen, so as to identify the fingerprint. Since this technology senses signals through light sensing, no super composite film is arranged at the position corresponding to the fingerprint hole area, so that although the fingerprint hole area has excellent optical performance (high transmittance), the impact resistance of the screen at the fingerprint hole area is greatly reduced, so that when the screen is impacted, it is easy to be pressed and produce black spots at the position corresponding to the fingerprint hole, thereby losing effectiveness.

[0033] The technical solutions in the embodiments of the present application will be clearly and completely described in combination 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 the embodiments. Based on the embodiments in the present application, all other embodiments obtained by a person skilled in the art without creative effort fall within the protection scope of the present application.

[0034] The present application provides a display module 100 and a display device 1000. The following are described in detail respectively. It should be noted that the description order of the following embodiments is not limited as the preferred order of the embodiments.

[0035] In a first aspect, the present application provides a display module 100, which comprises a display panel 1, a support layer 2 and a buffer layer 3. The display panel 1 comprises a display side 11 and a back side 12 arranged oppositely. The display panel 1 has a display area A and a fingerprint identification area B in the display area A on the display side 11. The support layer 2 is arranged on the back side 12 of the display panel 1. The buffer layer 3 is arranged on the side of the support layer 2 away from the display panel 1, and the buffer layer 3 is provided with a light-sensitive through hole 31 at a position corresponding to the fingerprint identification area B.

[0036] The present application does not make specific limitations on the type of the display panel 1. The display panel 1 can be an OLED display panel, a quantum dot display panel, a liquid crystal display panel or the like. The display panel 1 can be hard or flexible.

[0037] Generally, the display panel 1 is provided with a light-sensitive element at the fingerprint identification area B, which is used for optical fingerprint identification. When a user performs fingerprint identification, light passes through the texture (ridge line and valley line) of the fingerprint, reflects light of different brightness, and is received by the sensor under the display panel 1, so as to identify the fingerprint.

[0038] The application does not make specific restrictions on the form of the support layer 2. The support layer 2 is used to provide rigid support to the display panel 1 to prevent the display panel 1 from being damaged in subsequent processes due to lack of rigidity. The support layer 2 can be a single-layer structure or a laminated structure. The support layer 2 is a single-layer structure in an example. Moreover, the material of the support layer 2 is a light-transmitting material with a light transmittance greater than or equal to 90%, such as COP (CycloOlefin Polymer) or acrylic. Therefore, the support layer 2 can be provided in a continuous and uninterrupted structure, i.e., the support layer 2 is not provided with a through hole penetrating through the entire support layer 2, so that the support layer 2 has no hollowed-out area, thereby improving the support stability of the support layer 2.

[0039] The application does not make specific restrictions on the form of the buffer layer 3. Preferably, the buffer layer 3 is provided as an SCF layer (Super Clean Foam) having the functions of buffering and heat dissipation. The SCF layer can have a structure commonly known in the art, such as an SCF layer including, in sequence, an adhesive layer, a foam layer, an organic material layer, and a metal layer. The adhesive layer is close to the support layer 2 and adheres to the support layer 2. The material of the adhesive layer is, for example, Embo. The foam layer has the functions of light shielding and buffering. The material of the foam layer is, for example, foam. The organic material layer has the function of reinforcement to improve the reliability of the SCF layer. The material of the organic material layer is, for example, polyimide. The metal layer has the function of heat dissipation. The material of the metal layer is, for example, copper foil.

[0040] It can be understood that, since the buffer layer 3 is a composite material and not light-transmitting, a light-permeable through hole 31 needs to be provided on the buffer layer 3 at a position corresponding to the fingerprint recognition area B to improve the light transmittance at the fingerprint recognition area B, thereby improving the fingerprint recognition sensitivity.

[0041] The provision of the light-permeable through hole 31 can improve the light transmittance at the fingerprint recognition area B, but greatly reduces the impact energy resistance of the screen body at the fingerprint hole area. By providing a light-transmitting gasket 4 in the light-permeable through hole 31, the light-transmitting gasket 4 can support the support layer 2 and the display panel 1 when the display module 100 is impacted, so as to avoid large deformation of the display panel 1 at a position corresponding to the light-permeable through hole 31, thereby improving the impact resistance of the display panel 1 at the position corresponding to the light-permeable through hole 31 and avoiding the generation of black spots at the position corresponding to the light-permeable through hole 31 due to extrusion of the display panel 1.

[0042] And the light-transmitting gasket 4 comprises a first spacer layer 41 and a second spacer layer 42 which are arranged in a stacked manner, the first spacer layer 41 is arranged close to the support layer 2, and the second spacer layer 42 has an elastic modulus greater than that of the first spacer layer 41. When the display module 100 is impacted, the first spacer layer 41 can produce greater deformation due to its smaller elastic modulus, thereby dissipating impact energy through deformation and reducing resonance. The second spacer layer 42 has higher hardness and yield strength due to its larger elastic modulus, and can dissipate a large amount of impact energy through its own deformation on the basis of providing support force to the first spacer layer 41, thereby improving the anti-impact performance of the display panel 1 at the position corresponding to the light-sensitive through hole 31, and further improving the reliability of the display module 100.

[0043] The present application does not make specific restrictions on the structure of the second spacer layer 42. The second spacer layer 42 can be arranged in a single-film layer structure or a multi-film layer structure.

[0044] Please refer to Figure 1 In the first embodiment of the present application, the second spacer layer 42 is arranged in a single-film layer structure, and the ratio of the elastic modulus E2 of the second spacer layer 42 to the elastic modulus E1 of the first spacer layer 41 is set to

[0045] Please refer to Figure 2 In the second embodiment of the present application, the second spacer layer 42 is arranged in a single-film layer structure, and the ratio of the elastic modulus E2 of the second spacer layer 42 to the elastic modulus E1 of the first spacer layer 41 is set to

[0046] In the first embodiment and the second embodiment of the present application, the second spacer layer 42 is arranged in a single-film layer structure, and the elastic modulus E1 of the first spacer layer is set to 10KPa-500KPa. The elastic modulus E1 of the first spacer layer 41 is much smaller than the elastic modulus E2 of the second spacer layer 42. When the display module 100 is impacted, the first spacer layer 41 can produce greater deformation due to its smaller elastic modulus, thereby dissipating impact energy through deformation and reducing resonance.

[0047] Compared with the second embodiment, in the first embodiment of the present application, the elastic modulus E2 of the second spacer layer 42 is smaller. When the display module 100 is impacted, the second spacer layer 42 can increase the bearing area of impact kinetic energy by deformation, convert point impact into surface impact, thereby dissipating impact kinetic energy and playing a role in buffering and damping, thereby improving the anti-impact performance of the display panel 1 at the position corresponding to the light-sensitive through hole 31, and further improving the reliability of the display module 100.

[0048] In the second embodiment of the present application, the second spacer layer 42 has a relatively large elastic modulus E2, so as to have a relatively high hardness and yield strength, and is capable of consuming a large amount of impact energy through its own deformation on the basis of providing a good supporting force for the first spacer layer 41, thereby improving the impact resistance of the display panel 1 at the position corresponding to the light-permeable via hole 31, and further improving the reliability of the display module 100.

[0049] In the first embodiment, the elastic modulus E2 of the second spacer layer 42 is not specifically limited. Preferably, the elastic modulus E2 of the second spacer layer 42 is set to 1 GPa to 10 GPa. The material of the second spacer layer 42 includes one of foam, silica gel, and non-Newtonian fluid cushioning material.

[0050] In the second embodiment, the elastic modulus E2 of the second spacer layer 42 is not specifically limited. Preferably, the elastic modulus E2 of the second spacer layer 42 is set to 10 GPa to 200 GPa. The material of the second spacer layer 42 includes one of PMMA (polymethyl methacrylate), PC (polycarbonate), COP (cyclo olefin copolymer), borosilicate glass, and transparent composite material. In this way, the second spacer layer 42 not only has a relatively high hardness and yield strength, but also has a light transmittance greater than or equal to 90%.

[0051] Meanwhile, the rigidity and mechanical properties of the first spacer layer 41 and the second spacer layer 42 are adjusted by adjusting the thicknesses of the first spacer layer 41 and the second spacer layer 42.

[0052] The thickness of the first spacer layer 41 is not specifically limited. The thickness T1 of the first spacer layer 41 is set to 0 μm to 50 μm. In combination with the above limitation on the elastic modulus of the first spacer layer 41, the first spacer layer 41 can be configured as an adhesive layer 423, and in this case, the second spacer layer 42 is adhered to the support layer 2 through the first spacer layer 41. As the adhesive layer 423, the thickness T1 of the first spacer layer 41 is usually set to 20 μm.

[0053] The thickness of the second spacer layer 42 is not specifically limited. The thickness T2 of the second spacer layer 42 is set to 0 μm to 200 μm. In order to ensure the rigidity of the second spacer layer 42, the thickness T2 of the second spacer layer 42 is greater than the thickness T1 of the first spacer layer 41. Usually, the thickness of the buffer layer 3 is set to 200 μm to 220 μm, so when the thickness T2 of the second spacer layer 42 is set to 200 μm, the total thickness of the light-permeable gasket 4 is the same as the depth of the light-permeable via hole 31.

[0054] As mentioned above, in the thickness direction of the display module 100, the ratio of the thickness T2 of the second spacer 42 to the thickness T1 of the first spacer 41 is set to

[0055] Please refer to Figure 3 In the third embodiment of the present application, the second spacer 42 comprises a first sub-layer 421, a second sub-layer 422 and an adhesive layer 423. The first sub-layer 421 is arranged on the side of the first spacer 41 away from the support layer 2. The second sub-layer 422 is arranged on the side of the first sub-layer 421 away from the first spacer 41. The first adhesive layer is arranged between and adheres the first sub-layer 421 and the second sub-layer 422. The elastic modulus of the first sub-layer 421 is different from that of the second sub-layer 422, and the elastic modulus of the first sub-layer 421 and the elastic modulus of the second sub-layer 422 are both greater than the elastic modulus of the first spacer 41.

[0056] In the third embodiment, the second spacer 42 is arranged in a multi-film structure. The elastic modulus of the first sub-layer 421 is different from that of the second sub-layer 422, and the first sub-layer 421 and the second sub-layer 422 are adhered by the first adhesive layer. When the display module 100 is impacted, the first spacer 41 can produce a larger deformation due to its smaller elastic modulus, thereby dissipating impact energy and reducing resonance through deformation. After the impact energy is transmitted to the second spacer 42, it is sequentially transmitted through the first sub-layer 421, the first adhesive layer and the second sub-layer 422, which can further consume a large amount of impact energy, thereby improving the anti-impact performance of the display panel 1 at the position corresponding to the light-sensitive via 31, and further improving the reliability of the display module 100.

[0057] The application does not make specific limitation on the relationship between the elastic modulus of the first sub-layer 421 and the second sub-layer 422. In an embodiment, the elastic modulus of the first sub-layer 421 is greater than that of the second sub-layer 422; when the display module 100 is impacted, the first spacer 41 can generate greater deformation due to its smaller elastic modulus, thereby dissipating impact energy through deformation and reducing resonance; the first sub-layer 421 with greater elastic modulus has higher hardness and yield strength, and can dissipate a large amount of impact energy through its own deformation on the basis of providing support force for the first spacer 41, and meanwhile, the second sub-layer 422 with smaller elastic modulus can absorb impact energy through its own deformation when receiving impact force transmitted from the first sub-layer 421, which can decompose the stress of the display panel 1 at the light-permeable through hole 31 and prevent the light-transmitting gasket 4 from being broken due to the overall elastic modulus being too large.

[0058] In another embodiment, the elastic modulus of the first sub-layer 421 is smaller than that of the second sub-layer 422; when the display module 100 is impacted, the first spacer 41 can generate greater deformation due to its smaller elastic modulus, thereby dissipating impact energy through deformation and reducing resonance; the first sub-layer 421 with smaller elastic modulus can dissipate impact energy through its greater deformation; the first adhesive layer between the first sub-layer 421 and the second sub-layer 422 can play a role in buffering and reducing resonance; meanwhile, the second sub-layer 422 with greater elastic modulus has higher hardness and yield strength, and can dissipate a large amount of impact energy through its own deformation on the basis of providing support force for the first spacer 41 and the first sub-layer 421; thereby improving the anti-impact performance of the display panel 1 at the position corresponding to the light-permeable through hole 31.

[0059] The application does not make specific limitation on the elastic modulus of the first sub-layer 421, the first adhesive layer and the second sub-layer 422.

[0060] Taking the example of "the elastic modulus of the first sub-layer 421 is smaller than that of the second sub-layer 422", the elastic modulus of the first sub-layer 421 is set to 1 GPa-10 GPa; the elastic modulus of the second sub-layer 422 is set to 10 GPa-200 GPa; the elastic modulus of the first adhesive layer is set to 10 KPa-500 KPa, and the elastic modulus of the first adhesive layer can be the same as or different from that of the first spacer 41.

[0061] Similarly, the application does not specifically limit the thickness of the first sub-layer 421, the first adhesive layer, and the second sub-layer 422. The thickness of the first sub-layer 421 is set to 0-200 μm; the thickness of the second sub-layer 422 is set to 0-200 μm; the thickness of the first sub-layer 421 and the second sub-layer 422 can be the same or different; the thickness of the first adhesive layer is set to 0 μm-50 μm, and the thickness of the first adhesive layer and the first spacer layer 41 can be the same or different. According to the above embodiment "the first spacer layer 41 is configured as an adhesive layer 423 and adheres to the second spacer layer 42 and the support layer 2", the first spacer layer 41 can have the same thickness and elastic modulus as the first adhesive layer.

[0062] According to the above embodiment, the first spacer layer 41 is set as a second adhesive layer, and the first spacer layer 41 adheres to the second spacer layer 42 and the support layer 2.

[0063] The application does not specifically limit the thickness of the light-transmitting gasket 4. The thickness of the light-transmitting gasket 4 is less than or equal to the depth of the light-sensitive through hole 31. That is, the light-transmitting gasket 4 does not exceed the circumference of the light-sensitive through hole 31, so as not to affect the overall structure of the display module 100.

[0064] In the embodiment of the application, the display module 100 further comprises a polarizer 5, an optical adhesive layer 6, and a cover plate 7. The polarizer 5 is arranged on the display side 11 of the display panel 1, the cover plate 7 is arranged on the side of the polarizer 5 away from the display panel 1, and the optical adhesive layer 6 is arranged between the polarizer 5 and the cover plate 7 and adheres the polarizer 5 and the cover plate 7.

[0065] In a second aspect, the embodiment of the application provides a display device 1000. The display device 1000 comprises a display module 100. It should be noted that the display module 100 is set as the above-mentioned display module 100, that is, the display module 100 comprises all the technical features of the above-mentioned display module 100, and the display device 1000 comprises all the embodiments of the above-mentioned display module 100, so as to have all the technical effects of the above-mentioned embodiments, which will not be described here.

Therefore, the features defined as "first" and "second" can explicitly or implicitly include one or more features.

[0068] The embodiments, implementation manners and related technical features of the present application can be combined or replaced with each other without conflict.

[0069] The above are only the preferred embodiments of the present application, and do not limit the present application in any form. Any simple modification, equivalent change and modification made to the above embodiments without departing from the technical solution content of the present application and in accordance with the technical essence of the present application still belongs to the scope of the technical solution of the present application.
