[0002] With the development of display technology, people have put forward higher requirements for the product quality and performance of display panels and display devices.

[0003] Existing display panels typically use organic polymer materials with low hardness and modulus to prepare the protective layer. This protective layer is directly bonded to the display layer through an adhesive layer. Due to the low modulus of the protective layer, scratches are easily left on the outer surface of the protective layer, reducing the product quality of the display panel. Moreover, it cannot be replaced, further lowering the overall product quality of the display panel. Summary of the Invention

[0045] 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 scope of protection of this application.

[0046] The following disclosure provides many different embodiments or examples for implementing different structures of this application. To simplify the disclosure, specific examples of components and arrangements are described below. Of course, these are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples; such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. In addition, various specific examples of processes and materials are provided in this application, but those skilled in the art will recognize the application of other processes and / or the use of other materials.

[0047] Please refer to Figure 1 The display module includes a panel body 1, an adhesive layer 2, an ultra-thin glass 3, a first resin layer 4 and a second resin layer 5 sequentially disposed on the light-emitting side of the panel body 1, and a composite support layer 6 disposed on the side of the panel body 1 away from the adhesive layer 2. The outermost surface of the display module uses the first resin layer 4 and the second resin layer 5, which have low hardness and modulus. The ultra-thin glass 3, the first resin layer 4, and the second resin layer 5 are all directly bonded to the panel body 1 through the adhesive layer. Since the second resin layer 5 has a low modulus, it is easy to leave scratches on the outer surface of the second resin layer 5, which reduces the product quality of the display module and makes it irreplaceable.

[0048] Please refer to Figure 2 This application provides a display module, which includes a display area 101 and a non-display area 102 adjacent to the display area 101. The display module also includes a panel body 11, a cover layer 10, a composite protective layer 20, a first adhesive layer 30, and a first shielding layer 14.

[0049] The panel body 11 is located in the display area 101 and the non-display area 102; the cover layer 10 is disposed on the light-emitting side of the panel body 11; the composite protective layer 20 is disposed on the side of the cover layer 10 away from the panel body 11, and the composite protective layer 20 includes ultra-thin glass; the first adhesive layer 30 is disposed between the cover layer 10 and the composite protective layer 20; and the first shielding layer 14 is disposed between the panel body 11 and the cover layer 10.

[0050] Furthermore, the water droplet angle on the surface of the composite protective layer 20 that contacts the first adhesive layer 30 is greater than or equal to 100°, and / or the water droplet angle on the surface of the cover layer 10 that contacts the first adhesive layer 30 is greater than or equal to 100°. The composite protective layer 20 is disposed within the display area 101, and the edge of the composite protective layer 20 is spaced apart from the non-display area 102. The orthographic projection of the first shielding layer 14 on the panel body 11 is spaced apart from the orthographic projection of the composite protective layer 20 on the panel body 11.

[0051] In practical application, this embodiment of the application sets the water droplet angle on the surface of the composite protective layer 20 in contact with the first adhesive layer 30 to be greater than or equal to 100°, and / or the water droplet angle on the surface of the cover layer 10 in contact with the first adhesive layer 30 to be greater than or equal to 100°. This makes it easy to separate the composite protective layer 20 and the first adhesive layer 30, and / or to easily separate the cover layer 10 and the first adhesive layer 30. Consequently, the composite protective layer 20 can be separated and removed. Therefore, this embodiment of the application can replace the composite protective layer 20, improving the product quality of the display module. Furthermore, the composite protective layer 20 is disposed within the display area 101, and the edge of the composite protective layer 20 is adjacent to the non-display area 101. 02. The first shielding layer 14 is spaced apart, thereby reducing interference and overlap between the composite protective layer 20 and the edge fixing structure of the display module. For example, it reduces interference and overlap between the composite protective layer 20 and the edge pressing strip, and improves the yield and success rate during the replacement of the composite protective layer 20. In addition, the composite protective layer 20 in this embodiment is located on the outer surface of the display module, and the composite protective layer 20 includes ultra-thin glass. The elastic modulus of ultra-thin glass is relatively high, which can improve the support of the outer surface of the display module. Thus, when the user performs touch operation on the display module, it can effectively increase the user's touch texture, reduce the probability of pressing imprints, and improve the phenomenon that imprints are difficult to recover.

[0052] Specifically, please continue to refer to Figure 2 In one embodiment of this application, the display module includes a panel body 11, a cover layer 10 disposed between the panel body 11 and the composite protective layer 20, and a second adhesive layer 13 located between the panel body 11 and the cover layer 10, wherein the panel body 11 and the cover layer 10 are bonded together by the second adhesive layer 13.

[0053] In this embodiment, the cover layer 10 includes a cover plate layer 12 disposed on the side of the second adhesive layer 13 away from the panel body 11, and the cover plate layer 12 is attached to the panel body 11 through the second adhesive layer 13.

[0054] In some embodiments, the panel body 11 may include a substrate and a thin-film transistor layer disposed on the substrate, the thin-film transistor layer being located on the side of the substrate near the cover layer 10. The substrate may be a rigid substrate, such as a glass substrate; or, the substrate may be a flexible substrate, such as a substrate formed of polyimide. When the substrate is a flexible substrate, it may be formed of multiple sub-substrates of the same material, such as polyimide, with adjacent sub-substrates bonded together by adhesive sub-layers.

[0055] In some embodiments, the thin-film transistor layer includes a thin-film transistor, which includes a semiconductor located on a substrate. The semiconductor may be formed of polycrystalline silicon or a metal oxide (such as indium gallium zinc oxide). The semiconductor is divided into a channel region and source and drain regions formed on either side of the channel region. The thin-film transistor layer also includes a first gate insulating layer covering the semiconductor. The thin-film transistor also includes a first gate formed on the first gate insulating layer, overlapping the channel region. The first gate may be formed as multiple layers or a single layer comprising a low-resistance material such as Al, Ti, Mo, Cu, Ni, or alloys thereof, or a material with high corrosion resistance. The thin-film transistor layer also includes a second gate insulating layer covering the first gate. The thin-film transistor also includes a second gate located on the second gate insulating layer, overlapping the first gate. The second gate may be formed as multiple layers or a single layer comprising a low-resistance material such as Al, Ti, Mo, Cu, Ni, or alloys thereof, or a material with high corrosion resistance. The thin-film transistor layer also includes a first interlayer insulating layer formed on the second gate. The first interlayer insulating layer, the first gate insulating layer, and the second gate insulating layer include source contact holes and drain contact holes, and the source region and the drain region are exposed through the source contact holes and drain contact holes, respectively.

[0056] The thin-film transistor also includes a source and a drain disposed on the same layer, both formed on the first interlayer insulating layer. The source is connected to the source region through a source contact hole, and the drain is connected to the drain region through a drain contact hole. The source and drain can be multiple layers or a single layer formed of low-resistance materials such as Al, Ti, Mo, Cu, Ni, or their alloys, or materials with high corrosion resistance. For example, the source and drain can be a triple layer of Ti / Cu / Ti, Ti / Ag / Ti, Ti / Al / Ti, or Mo / Al / Mo, or other single-layer or multi-layer structures.

[0057] In some embodiments, the panel body 11 further includes a planarization layer located between the thin-film transistor layer and the light-emitting layer, the planarization layer covering the source and drain.

[0058] In some embodiments, the panel body 11 further includes an anode layer located on the side of the planarization layer away from the thin-film transistor layer. The anode layer includes a plurality of anodes, each anode corresponding to a pixel unit. Each anode is electrically connected to a thin-film transistor. The planarization layer includes anode contact holes through which the anodes contact the source or drain of the thin-film transistor.

[0059] In some embodiments, the panel body 11 further includes a pixel definition layer disposed on the side of the planarization layer away from the thin-film transistor layer. The pixel definition layer includes pixel definition portions and openings located between the pixel definition portions. The panel body 11 also includes a light-emitting layer comprising a plurality of pixel units. The pixel units are located within the openings. The openings expose a portion of the anode and cover the edge of the anode. The pixel units may include red pixel units, green pixel units, and blue pixel units.

[0060] In some embodiments, the panel body 11 further includes a cathode layer covering the light-emitting layer. In the direction from the anode to the cathode layer, the light-emitting layer includes a hole-injecting organic layer, a light-emitting material layer, and an electronic organic layer stacked sequentially. The hole-injecting organic layer may include a hole injection layer and a hole transport layer, with the hole injection layer in direct contact with the anode and the hole transport layer located between the hole injection layer and the light-emitting material layer. The hole-injecting organic layer may also include an electron blocking layer located between the hole transport layer and the light-emitting material layer. The electronic organic layer may include an electron injection layer and an electron transport layer, with the electron injection layer in direct contact with the cathode layer and the electron transport layer located between the electron injection layer and the light-emitting material layer. The electronic organic layer may also include a hole blocking layer located between the electron transport layer and the light-emitting layer.

[0061] In some embodiments, the panel body 11 further includes an encapsulation layer located on the side of the cathode layer away from the light-emitting layer. The encapsulation layer is formed by alternating stacking of multiple inorganic and organic film layers. For example, along the direction from the substrate to the thin-film transistor layer, the encapsulation layer includes a first inorganic encapsulation sublayer, a first organic encapsulation sublayer, and a second inorganic encapsulation sublayer.

[0062] In some embodiments, the panel body 11 further includes a touch layer located on the side of the encapsulation layer away from the light-emitting layer. The touch layer can implement touch functionality in a self-capacitive or mutual-capacitive manner. When the touch layer implements touch functionality in a self-capacitive manner, the touch layer may have only one touch metal layer.

[0063] When the touch layer implements touch functionality using capacitive touch, the touch layer includes a first touch metal layer, a touch insulating layer, and a second touch metal layer. The touch insulating layer is located on the side of the first touch metal layer furthest from the encapsulation layer, and the second touch metal layer is also located on the side of the touch insulating layer furthest from the encapsulation layer. The first touch metal layer can be directly disposed on the encapsulation layer, or a spacer layer can be disposed between the first touch layer and the encapsulation layer. The spacer layer can include an inorganic spacer layer and / or an organic spacer layer. The first touch metal layer includes a first touch electrode, a second touch electrode, and a first bridging wire; the second touch metal layer includes a second bridging wire. Both the first and second touch electrodes are metal networks. Alternatively, the second touch metal layer includes a first touch electrode, a second touch electrode, and a first bridging wire, and the first touch metal layer includes a second bridging wire.

[0064] In some embodiments, the display module may be a display module with a polarizer (Pol-less) architecture, and the panel body 11 may further include a color filter layer, which is located on the side of the light-emitting layer away from the thin-film transistor layer.

[0065] In some embodiments, when the cover layer 10 is a cover plate layer 12, the material of the cover layer 10 may include at least one of polyethylene terephthalate, polycarbonate, polymethyl methacrylate and polyimide, and the material of the second adhesive layer 13 may include OCA optical adhesive.

[0066] The composite protective layer 20 is attached to the light-emitting surface of the panel body 11 and is attached to the cover layer 10 through the first adhesive layer 30. The water droplet angle of the surface of the composite protective layer 20 in contact with the first adhesive layer 30 is greater than or equal to 100°, and / or the water droplet angle of the surface of the cover layer 10 in contact with the first adhesive layer 30 is greater than or equal to 100°. Therefore, the composite protective layer 20 and the first adhesive layer 30 are easily separated, and / or the cover layer 10 and the first adhesive layer 30 are easily separated. Thus, the composite protective layer 20 can be separated and removed. Therefore, when the composite protective layer 20 is scratched during the actual use of the panel, the present application embodiment can replace the composite protective layer 20, thereby improving the product quality of the display module.

[0067] Furthermore, the composite protective layer 20 is disposed within the display area 101, and the edge of the composite protective layer 20 is spaced apart from the non-display area 102. That is, by designing the edge of the composite protective layer 20 in an inward manner, the composite protective layer 20 can avoid interference and overlap with the edge fixing structure of the display module. Thus, the replacement of the composite protective layer 20 will not be affected by the edge fixing structure, thereby improving the success rate and yield of replacing the composite protective layer 20.

[0068] In some embodiments, the design of the hydrophobicity of the surface of the cover layer 10 in contact with the first adhesive layer 30 and the hydrophobicity of the surface of the composite protective layer 20 in contact with the first adhesive layer 30 facilitates the separation of the cover layer 10 from the first adhesive layer 30, or the separation of the composite protective layer 20 from the first adhesive layer 30. This makes it easier to separate the cover layer 10 from the composite protective layer 20, reduces the difficulty of removing the composite protective layer 20, and extends the service life of the display module.

[0069] In some embodiments, when the hydrophobicity of the surface of the cover layer 10 in contact with the first adhesive layer 30 is stronger than that of the surface of the composite protective layer 20 in contact with the first adhesive layer 30, the water droplet angle of the surface of the cover layer 10 in contact with the first adhesive layer 30 is greater than or equal to 100 degrees. For example, it can be 105 degrees, 108 degrees, 110 degrees, 115 degrees, 118 degrees, 120 degrees, etc., so that the surface of the cover layer 10 in contact with the first adhesive layer 30 has sufficient hydrophobicity, which is beneficial to the separation of the cover layer 10 and the first adhesive layer 30. The water droplet angle can be measured using a water droplet angle tester.

[0070] In some embodiments, the water droplet angle of the surface of the cover layer 10 near the first adhesive layer 30 is greater than the water droplet angle of the surface of the composite protective layer 20 near the first adhesive layer 30. For example, when the water droplet angle of the surface of the cover layer 10 in contact with the first adhesive layer 30 is greater than or equal to 100 degrees, the water droplet angle of the surface of the composite protective layer 20 in contact with the first adhesive layer 30 is greater than or equal to 20 degrees and less than or equal to 50 degrees, so that the surface of the composite protective layer 20 in contact with the first adhesive layer 30 has sufficient hydrophilicity, so that there is sufficient adhesion between the composite protective layer 20 and the first adhesive layer 30, so that when the composite protective layer 20 is separated from the cover layer 10, the first adhesive layer 30 can be removed together, and no first adhesive layer 30 remains on the light-emitting surface of the cover layer 10.

[0071] In some embodiments, a surface conditioning layer (not shown) is provided on the side of the cover layer 10 near the first adhesive layer 30, and / or a surface conditioning layer is provided on the side of the composite protective layer 20 near the first adhesive layer 30. The material of the surface conditioning layer is selected from at least one of fluorine-containing inorganic materials and fluorine-containing organic materials, for example, it may be selected from fluorosilicone compounds.

[0072] For example, a surface conditioning layer is provided on the side of the cover layer 10 near the composite protective layer 20, and / or a surface conditioning layer is provided on the side of the substrate layer 21 near the cover layer 10.

[0073] In some embodiments, the first shielding layer 14 is disposed on the side of the cover layer 10 near the panel body 11; further, the first shielding layer 14 is disposed on the side of the cover layer 10 near the second adhesive layer 13; and the first shielding layer 14 is distributed around the periphery of the cover layer 10 for shielding and preventing light leakage; and the orthographic projection of the composite protective layer 20 on the panel body 11 and the orthographic projection of the first shielding layer 14 on the panel body 11 are spaced apart.

[0074] In some embodiments, the first shielding layer 14 is disposed in the non-display area 102, and the edge of the first shielding layer 14 near the display area 101 is spaced apart from the display area 101 to avoid the first shielding layer 14 blocking the light emitted from the display area 101.

[0075] In some embodiments, the distance between the orthographic projection of the composite protective layer 20 on the panel body 11 and the orthographic projection of the first shielding layer 14 on the panel body 11 is greater than or equal to 0.4 mm and less than or equal to 1.3 mm, for example, it can be 0.4 mm, 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1 mm, 1.1 mm, 1.2 mm or 1.3 mm. When the distance between the orthographic projection of the composite protective layer 20 on the panel body 11 and the orthographic projection of the first shielding layer 14 on the panel body 11 is too small, due to the limitation of the bonding accuracy of the composite protective layer 20, the composite protective layer 20 is prone to interference and overlap with the edge fixing structure located in the non-display area 102. When the distance between the orthographic projection of the composite protective layer 20 on the panel body 11 and the orthographic projection of the first shielding layer 14 on the panel body 11 is too large, it will result in a large area on the light-emitting surface of the panel body 11 that is not covered by the composite protective layer 20, thereby reducing the protective effect of the composite protective layer 20 on the panel body 11.

[0076] In some embodiments, the first shielding layer 14 is disposed around the display area 101, and the width L4 of the first shielding layer 14 along the direction perpendicular to its surrounding direction is less than or equal to 1 mm, for example, it can be 0.1 mm, 0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm or 1 mm; wherein, if the width of the first shielding layer 14 is too large, it will increase the bezel width of the display module, which is not conducive to achieving a narrow bezel of the display module.

[0077] In some embodiments, the distance L3 between the edge of the first shielding layer 14 near the display area 101 and the display area 101 is greater than or equal to 0.2 mm and less than or equal to 0.3 mm, for example, it can be 0.2 mm, 0.25 mm or 0.3 mm.

[0078] In some embodiments, the material of the first shielding layer 14 may include ink or other light-shielding materials.

[0079] In some embodiments, the distance L2 between the edge of the composite protective layer 20 and the non-display area 102 is greater than or equal to 0.2 mm and less than or equal to 1 mm. For example, it can be 0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm or 1 mm, so as to leave sufficient distance between the composite protective layer 20 and the edge strip 50, and to effectively protect the light-emitting surface of the panel body 11.

[0080] In some embodiments, the distance between the edge of the composite protective layer 20 and the non-display area 102 is greater than the distance between the edge of the first shielding layer 14 near the display area 101 and the display area 101. It should be noted that during the application process, the composite protective layer 20 may be repaired and replaced manually, while the first shielding layer 14 is usually formed mechanically. As a result, the bonding accuracy of the composite protective layer 20 is worse than that of mechanical bonding. Therefore, in this embodiment, the distance between the composite protective layer 20 and the non-display area 102 is set to be greater than the distance between the first shielding layer 14 and the display area 101, so as to effectively reduce the probability of interference of the composite protective layer 20 due to accuracy issues during the bonding process.

[0081] Furthermore, in some embodiments, the composite protective layer 20 includes a substrate layer 21, a protective layer 22 disposed on the side of the substrate layer 21 away from the cover layer 10, and a third adhesive layer 23 disposed between the substrate layer 21 and the protective layer 22, wherein the substrate layer 21 is bonded to the protective layer 22 through the third adhesive layer 23.

[0082] In some embodiments, the material of the substrate layer 21 may include at least one of polyethylene terephthalate, polycarbonate, polymethyl methacrylate, and polyimide, and the material of the third adhesive layer 23 may include OCA optical adhesive; the protective layer 22 includes an ultra-thin glass 221 disposed on the side of the substrate layer 21 away from the cover layer 10 and a protective portion 222 covering the surface of the ultra-thin glass 221 away from the substrate layer 21 and the side surface of the ultra-thin glass 221, wherein the ultra-thin glass 221 is located on the side of the third adhesive layer 23 away from the substrate layer 21, and the protective portion 222 covers the ultra-thin glass 221 to improve the protective effect on the ultra-thin glass 221.

[0083] It is understood that the protective layer 22 in this embodiment is located on the outer surface of the display module, and the protective layer 22 includes ultra-thin glass 221. The ultra-thin glass 221 has a relatively high elastic modulus, which can improve the support of the outer surface of the display module. In turn, when the user performs touch operation on the display module, it can effectively increase the user's touch texture, reduce the probability of pressing imprints, and improve the phenomenon that imprints are difficult to recover.

[0084] In some embodiments, the thickness of the ultrathin glass 221 is greater than or equal to 30 micrometers and less than or equal to 50 micrometers, and the elastic modulus of the ultrathin glass 221 is greater than or equal to 65 GPa and less than or equal to 75 GPa, for example, it can be 65 GPa, 66 GPa, 67 GPa, 68 GPa, 69 GPa, 70 GPa, 71 GPa, 72 GPa, 73 GPa, 74 GPa or 75 GPa.

[0085] In some embodiments, the thickness L1 of the protective portion 222 covering the side of the ultra-thin glass 221 in the direction away from the ultra-thin glass 221 is greater than or equal to 0.1 mm and less than or equal to 0.3 mm, for example, it can be 0.1 mm, 0.2 mm or 0.3 mm; wherein, the thickness of the protective portion 222 covering the side of the ultra-thin glass 221 and the edge effect stress are verified in the embodiments of this application to obtain the results shown in Table 1 below.

[0086] Table 1

[0087] thickness 0.1 0.2 0.3 Tensile strain / % 1.7 2.3 2.6 Stress / MPa 2.2 2.4 2.9

[0088] As can be seen from Table 1, the greater the thickness of the protective portion 222 covering the side of the ultra-thin glass 221, the greater the edge effect stress and strain, and the higher the risk of film peeling. In this embodiment, by designing the thickness of the protective portion 222 covering the side of the ultra-thin glass 221, the protection effect of the ultra-thin glass 221 can be improved on the one hand, and the edge effect stress can be avoided due to the excessive thickness of the protective portion 222 covering the side of the ultra-thin glass 221, thus reducing the probability of film peeling in the composite protective layer 20.

[0089] In some embodiments, the side surfaces of the substrate layer 21, the protective layer 22, and the third adhesive layer 23 are flush, and the side surfaces of the substrate layer 21, the protective portion 222, and the third adhesive layer 23 are flush. Since the composite protective layer 20 is located within the display area 101, and the edge of the composite protective layer 20 is also located within the display area 101, the embodiments of this application set the edge of the composite protective layer 20 to be flush, so that the composite protective layer 20 has only one boundary in optical imaging, which can avoid the composite protective layer 20 from affecting the display effect of the display module.

[0090] It is understood that if the step difference between the sides of the substrate layer 21, the protective layer 22, and the third adhesive layer 23 is within 0.1 mm, it can be considered that the sides of the substrate layer 21, the protective layer 22, and the third adhesive layer 23 are flush; more preferably, the step difference between the sides of the substrate layer 21, the protective layer 22, and the third adhesive layer 23 can be 0.01 mm, 0.02 mm, 0.03 mm, 0.04 mm, 0.05 mm, 0.06 mm, 0.07 mm, 0.08 mm, 0.09 mm, or 0.1 mm.

[0091] Furthermore, the display module also includes a composite support layer 40 disposed on the side of the panel body 11 away from the cover layer 10, and the composite support layer 40 is used to support and protect the panel body 11.

[0092] In some embodiments, the composite support layer 40 may include a back plate 41, a light-shielding layer 42, and a support plate 43, which are sequentially stacked on the side of the panel body 11 away from the cover layer 10; wherein, the edge of the light-shielding layer 42 may extend beyond or not extend beyond the edge of the back plate 41, and the edge of the support plate 43 may extend beyond or not extend beyond the edge of the back plate 41, which can be selected according to actual needs and is not specifically limited here.

[0093] In some embodiments, a back plate 41 is disposed on the side of the panel body 11 away from the cover layer 10. The material of the back plate 41 can be a flexible material, such as polyimide, to maintain the bending performance of the display module 100. A light-shielding layer 42 is disposed on the side of the back plate 41 away from the panel body 11. The material of the light-shielding layer 42 can be selected from a black, flexible material, such as black polyimide. A support plate 43 is disposed on the side of the light-shielding layer 42 away from the back plate 41. The material of the support plate 43 can be selected from a metal material with good heat dissipation, such as stainless steel. Both the support plate 43 and the back plate 41 can provide a certain degree of fixation and support.

[0094] Please combine Figure 2 as well as Figure 3 The display module has a through hole 110 and also includes a sensor 60 disposed on the side of the composite support layer 40 away from the panel body 11, corresponding to the through hole 110. The field of view 601 of the sensor 60 at the panel body 11 is less than the minimum value of the aperture of the through hole 110, that is, the through hole 110 will not affect the light-sensing function of the sensor 60.

[0095] In some embodiments, the through hole 110 passes through a portion of the panel body 11 and the composite support layer 40. The display module also includes a second shielding layer 15. The orthographic projection of the inner wall of the through hole 110 onto the panel body 11 is located within the coverage area of ​​the second shielding layer 15. The inner wall of the through hole 110 is irregular, meaning that the sides of each film layer through which the through hole 110 passes are not flush, so that the inner wall of the through hole 110 is irregular. In this embodiment, the orthographic projection of the inner wall of the through hole 110 onto the panel body 11 is located within the coverage area of ​​the second shielding layer 15, thereby shielding the interior of the irregular through hole 110 to avoid affecting the display and appearance of the display module.

[0096] In some embodiments, the field of view 601 of the sensor 60 at the plane where the second shielding layer 15 is located is not overlapped with the second shielding layer 15, so as to avoid the field of view 601 of the sensor 60 being blocked by the second shielding layer 15.

[0097] In some embodiments, the material of the second shielding layer 15 may include ink or other light-blocking materials, and the second shielding layer 15 is disposed on the side of the cover layer 10 near the second adhesive layer 13, and the second shielding layer 15 may be disposed around the through hole 110.

[0098] The through hole 110 passes through the panel body 11, the composite support layer 40, and the second adhesive layer 13. Within the through hole 110, the side of the second adhesive layer 13 is recessed towards the side away from the center of the through hole 110 relative to the side of the panel body 11. This can effectively reduce the probability of adhesive overflow in the second adhesive layer 13 within the through hole 110, reduce the impact of adhesive overflow on the sensor 60, and improve the sensing effect of the sensor 60.

[0099] In some embodiments, within the through hole 110, the side of the second adhesive layer 13 is recessed inward relative to the side of the panel body 11 by a distance greater than 0 mm and less than or equal to 0.1 mm, for example, 0.05 mm or 0.1 mm.

[0100] Continuing from the above, this embodiment of the application sets the water droplet angle on the surface of the composite protective layer 20 that contacts the first adhesive layer 30 to be greater than or equal to 100°, and / or the water droplet angle on the surface of the cover layer 10 that contacts the first adhesive layer 30 to be greater than or equal to 100°, making it easy to separate the composite protective layer 20 and the first adhesive layer 30, and / or making it easy to separate the cover layer 10 and the first adhesive layer 30. Therefore, the composite protective layer 20 can be separated and removed. Thus, this embodiment of the application can replace the composite protective layer 20, improving the product quality of the display module. Furthermore, the composite protective layer 20 is disposed within the display area 101, with its edge spaced apart from the non-display area 102, thereby reducing interference and overlap between the composite protective layer 20 and the edge fixing structure of the display module. For example, it reduces interference and overlap between the composite protective layer 20 and the edge strip, improving the yield and success rate during the replacement of the composite protective layer 20.

[0101] In another embodiment of this application, please refer to Figure 4 In this embodiment, the display area 101 further includes a bending area 1011 and a non-bending area 1012 adjacent to the bending area 1011. The thickness of the ultra-thin glass 221 in the bending area 1011 is less than the thickness of the ultra-thin glass 221 in the non-bending area 1012. On the one hand, this can make the thickness of the ultra-thin glass 221 in the non-bending area 1012 larger, thereby improving the surface mechanical buffering characteristics of the display module in the non-bending area 1012 and improving the tactile feel of the display module in the non-bending area 1012. On the other hand, this can make the thickness of the ultra-thin glass 221 in the bending area 1011 smaller, thereby improving the bending performance of the display module in the bending area 1011.

[0102] In some embodiments, the thickness of the ultrathin glass 221 in the non-bending region 1012 is greater than or equal to 70 micrometers and less than or equal to 300 micrometers, for example, it can be 70 micrometers, 100 micrometers, 150 micrometers, 200 micrometers, 250 micrometers or 300 micrometers; the thickness of the ultrathin glass 221 in the bending region 1011 is greater than or equal to 30 micrometers and less than or equal to 50 micrometers, for example, it can be 30 micrometers, 35 micrometers, 40 micrometers, 45 micrometers or 50 micrometers.

[0103] Continuing from the above, this embodiment of the application, by setting the water droplet angle of the surface of the composite protective layer 20 in contact with the first adhesive layer 30 to be greater than or equal to 100°, and / or the water droplet angle of the surface of the cover layer 10 in contact with the first adhesive layer 30 to be greater than or equal to 100°, makes it easy to separate the composite protective layer 20 and the first adhesive layer 30, and / or makes it easy to separate the cover layer 10 and the first adhesive layer 30. Therefore, the composite protective layer 20 can be separated and removed. Thus, this embodiment of the application can replace the composite protective layer 20, improving the product quality of the display module. Furthermore, the composite protective layer 20 is disposed within the display area 101, and the edge of the composite protective layer 20 is spaced apart from the non-display area 102, thereby reducing the risk of water droplet formation. Interference and overlap occur between the protective layer 20 and the edge fixing structure of the display module. For example, this reduces the interference and overlap between the composite protective layer 20 and the edge pressing strip, improving the yield and success rate during the replacement of the composite protective layer 20. On the other hand, the embodiments of this application can increase the thickness of the ultra-thin glass 221 in the non-bending area 1012. This can make the thickness of the ultra-thin glass 221 in the non-bending area 1012 larger, thereby improving the surface mechanical buffer characteristics of the display module in the non-bending area 1012 and improving the tactile feel of the display module in the non-bending area 1012. It can also make the thickness of the ultra-thin glass 221 in the bending area 1011 smaller, thereby improving the bending performance of the display module in the bending area 1011.

[0104] In another embodiment of this application, please refer to Figure 4 as well as Figure 5 In this embodiment, the composite protective layer 20 further includes a hard layer 25 disposed on the side of the protective layer 22 away from the substrate layer 21, so as to further improve the surface mechanical buffering characteristics of the display module.

[0105] The rigid layer 25 is disposed on the side of the protective part 222 away from the ultra-thin glass 221.

[0106] In some embodiments, the elastic modulus of the hard layer 25 is greater than or equal to 3 GPa and less than or equal to 7 GPa, and the thickness of the hard layer 25 can be greater than or equal to 3 micrometers and less than or equal to 10 micrometers, for example, it can be 3 micrometers, 4 micrometers, 5 micrometers, 6 micrometers, 7 micrometers, 8 micrometers, 9 micrometers or 10 micrometers.

[0107] In some embodiments, the material of the hard layer 25 can be a composite material that is a mixture or hybrid of organic and inorganic phases. The material of the hard layer 25 can be selected from silicon-containing inorganic-organic materials. For example, the material of the hard layer 25 can be selected from at least one of composite materials having silicon oxide and / or silicon nitride, polymers of siloxanes and acrylic, semi-siloxane polymers, and aliphatic or aromatic polymers containing inorganic silicon groups. When the hard layer 25 is selected from a composite material that is a mixture or hybrid of organic and inorganic phases, the surface of the hard layer 25 away from the protective layer 22 has high surface hardness and good recovery properties. For example, when the material of the hard layer 25 is selected from a polymer containing siloxanes, due to the good recovery properties of such materials, when a stylus or other hard object is slid across the surface of the hard layer 25 away from the protective layer 22 with considerable force, fine marks may be left on the surface. When the stylus or other hard object leaves the surface, the fine marks will automatically recover and disappear.

[0108] In some embodiments, the surface hardness of the hard layer 25 on the side away from the protective layer 22 is greater than or equal to 3H, and the surface hardness of the hard layer 25 on the side away from the protective layer 22 is less than or equal to 9H. For example, it can be 4H, 5H, 6H, 7H, 8H, etc.

[0109] In another embodiment of this application, please refer to Figure 4 as well as Figure 6 In this embodiment, the composite protective layer 20 further includes a spacer buffer layer 24 disposed on the side of the protective layer 22 away from the substrate layer 21 and a hard layer 25 disposed on the side of the spacer buffer layer 24 away from the protective layer 22. The spacer buffer layer 24 can be used to improve the buffering characteristics of the display module and improve the safety and explosion-proof characteristics of the display module.

[0110] The spacer buffer layer 24 is disposed on the side of the protective part 222 away from the ultra-thin glass 221.

[0111] In some embodiments, the elastic modulus of the spacer buffer layer 24 may be greater than or equal to 0.5 GPa and less than or equal to 5 GPa, for example, it may be 0.5 GPa, 1 GPa, 1.5 GPa, 2 GPa, 2.5 GPa, 3 GPa, 3.5 GPa, 4 GPa, 4.5 GPa, or 5 GPa. The thickness of the spacer buffer layer 24 may be greater than or equal to 10 micrometers and less than or equal to 40 micrometers, for example, it may be 10 micrometers, 15 micrometers, 20 micrometers, 25 micrometers, 30 micrometers, 35 micrometers, or 40 micrometers.

[0112] In some embodiments, the elastic modulus of the hard layer 25 is greater than or equal to 3 GPa and less than or equal to 7 GPa, for example, it can be 3 GPa, 3.5 GPa, 4 GPa, 4.5 GPa, 5 GPa, 5.5 GPa, 6 GPa, 6.5 GPa, or 7 GPa. The thickness of the hard layer 25 can be greater than or equal to 3 micrometers and less than or equal to 10 micrometers, for example, it can be 3 micrometers, 4 micrometers, 5 micrometers, 6 micrometers, 7 micrometers, 8 micrometers, 9 micrometers, or 10 micrometers.

[0113] In another embodiment of this application, please refer to Figure 7 This embodiment and Figure 2 The difference in the embodiment shown is that the display module in this embodiment does not have a depolarizer structure, the panel body 11 does not contain a color filter layer, and the cover layer 10 includes a polarizer 16 disposed on the light-emitting side of the panel body 11.

[0114] Specifically, the display module includes a panel body 11, a polarizer 16 disposed on the side of the panel body 11 near the composite protective layer 20, and a second adhesive layer 13 disposed between the panel body 11 and the polarizer 16, wherein the panel body 11 and the polarizer 16 are bonded together by the second adhesive layer 13.

[0115] In this embodiment, a surface conditioning layer is provided on the side of the polarizer 16 near the composite protective layer 20, and / or a surface conditioning layer is provided on the side of the substrate layer 21 near the panel body 11.

[0116] In this embodiment, the first shielding layer 14 and the second shielding layer 15 are both disposed on the side of the polarizer 16 near the second adhesive layer 13.

[0117] Continuing from the above, this embodiment of the application sets the water droplet angle on the surface of the composite protective layer 20 that contacts the first adhesive layer 30 to be greater than or equal to 100°, and / or the water droplet angle on the surface of the panel body 11 that contacts the first adhesive layer 30 to be greater than or equal to 100°, making it easy to separate the composite protective layer 20 and the first adhesive layer 30, and / or making it easy to separate the panel body 11 and the first adhesive layer 30. Therefore, the composite protective layer 20 can be separated and removed. Thus, this embodiment of the application can replace the composite protective layer 20, improving the product quality of the display module. Furthermore, the composite protective layer 20 is disposed within the display area 101, with its edge spaced apart from the non-display area 102, thereby reducing interference and overlap between the composite protective layer 20 and the edge fixing structure of the display module. For example, it reduces interference and overlap between the composite protective layer 20 and the edge pressing strip, improving the yield and success rate during the replacement of the composite protective layer 20.

[0118] In addition, this application embodiment also provides a display device, which includes the display module described in the above embodiments.

[0119] In some embodiments, please combine Figure 2 and Figure 8 The display device further includes a pressing strip 50. The cover layer 10 has a first surface and a second surface disposed opposite to each other. The first surface is the side of the cover layer 10 away from the panel body 11, and the second surface is the side of the cover layer 10 close to the panel body 11. The pressing strip 50 covers at least a portion of the first surface of the cover layer 10 away from the panel body 11, and the pressing strip 50 located on the first surface is spaced apart from the composite protective layer 20. The pressing strip 50 located on the first surface is located within the non-display area 102 and does not exceed the coverage range of the non-display area 102. Therefore, by designing the composite protective layer 20 in an inward-shrinking manner, this embodiment of the application can prevent interference and overlap between the composite protective layer 20 and the pressing strip 50. Thus, the replacement of the composite protective layer 20 will not be affected by the pressing strip 50, thereby improving the success rate and yield of replacing the composite protective layer 20.

[0120] In some embodiments, the orthographic projection of the edge strip 50 on the first surface onto the panel body 11 is within the coverage area of ​​the orthographic projection of the first shielding layer 14 on the panel body 11. Since the edge strip 50 on the first surface is within the coverage area of ​​the first shielding layer 14, and the first shielding layer 14 is located within the non-display area 102, when the width of the first shielding layer 14 is small and it is spaced apart from the display area 101, the setting range of the edge strip 50 is also small. This can further reduce the probability of interference and overlap between the composite protective layer 20 and the edge strip 50, and improve the yield and success rate of replacing the composite protective layer 20.

[0121] It is understood that since the display device includes the display module described in the above embodiments, the display device has the same beneficial effects as the display module described in the above embodiments, and will not be repeated here.

[0122] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions in other embodiments.
