Description

Technical Field

[0001] The present disclosure relates to the field of display technology, and in particular to a display module and a display device. Background Art

[0002] At present, the display module uses a cover plate with good strength and hardness, which can effectively protect the display panel in the display module. However, black spots frequently occur in the hole area of ​​the folding display module, so how to improve the anti-extrusion and impact resistance of the display module is a technical problem that needs to be solved in the display module. Utility Model Content

[0003] The purpose of the embodiments of the present disclosure is to provide a display module and a display device, so as to improve the anti-extrusion and anti-impact capabilities of the display module.

[0004] To achieve the above objectives, the embodiments of the present disclosure provide the following technical solutions:

[0005] In one aspect, a display module is provided, wherein the display module comprises a display panel and a supporting structure.

[0006] The display panel includes at least two first display parts and at least one second display part, one second display part is arranged between two adjacent first display parts and connected to two adjacent first display parts, and the second display part is bendable; at least one first display part has a first through hole that penetrates the first display part.

[0007] The supporting structure is arranged on the backlight side of the display panel, and includes at least two first supporting parts respectively arranged corresponding to the at least two first display parts, and at least one second supporting part arranged corresponding to the at least one second display part, and the second supporting part is bendable; at least one of the first supporting parts has a second through hole penetrating the first supporting part, and the first through hole and the second through hole are interconnected; the boundary of the first through hole is located outside the boundary of the second through hole, or the boundary of the first through hole coincides with the boundary of the second through hole.

[0008] It is understandable that in order to avoid interference between the camera and the supporting structure, the boundary of the second through hole can be set outside the boundary of the first through hole, that is, the first display part extends outward compared to the first supporting part. However, since the supporting structure generally adopts a rigid structure, when the display panel is squeezed by the outside or impacted by falling, the first display part extending outward compared to the first supporting part will be under concentrated pressure at the edge of the second through hole of the supporting structure due to the lack of support from the supporting structure at the bottom, resulting in stress concentration and thus causing the display panel to rupture.

[0009] In the above display module, the display panel includes at least two first display parts and at least one second display part, one second display part is arranged between two adjacent first display parts and connected to the two adjacent first display parts, and the second display part can be bent; at least one first display part has a first through hole penetrating the first display part, and the support structure is arranged on the backlight side of the display panel, including at least two first support parts respectively arranged corresponding to the at least two first display parts, and at least one second support part corresponding to the at least one second display part, and the second support part can be bent; at least one first support part has a second through hole penetrating the first support part, the first through hole and the second through hole are interlinked, and the boundary of the first through hole is located outside the boundary of the second through hole, or the boundary of the first through hole coincides with the boundary of the second through hole, so that, compared with the boundary of the second through hole being located outside the boundary of the first through hole, when the display panel is subjected to external extrusion or falling impact, the support structure can fully support the display panel, avoiding stress concentration caused by the edge of the second through hole of the support structure and the display panel and causing the display panel to rupture, thereby improving the mechanical ability of the display module to resist extrusion and impact.

[0059] refer to Figure 1A , Figure 1B and Figure 2 The embodiment of the present disclosure provides a display device 1000. From the perspective of the light-emitting type of the display device 1000, the display device 1000 may be an active light-emitting display device, such as an OLED (Organic Light-Emitting Diode) display device, a QLED (Quantum Dot Light Emitting Diodes) display device, or an MLED (Mini / Micro Light Emitting Display) display device. From the perspective of the shape of the display device 1000, the display device 1000 may be rectangular or circular. The embodiment of the present disclosure does not specifically limit this.

[0060] In the following, some embodiments of the present disclosure are schematically described by taking a rectangular display device as an example, but the implementation of the present disclosure is not limited thereto, and any other display devices may also be considered as long as the same technical concept is applied.

[0061] The display device 1000 is a product with an image display function. For example, the display device 1000 can be any device that displays either moving (e.g., video) or fixed (e.g., still images) and whether text or images. For example, the display device 1000 can be any product or component with a display function, such as a tablet computer, a car display, or a flight display. Figure 2 As shown, the display device 1000 is a foldable display device, such as a foldable mobile phone. Figure 2 The back of the foldable phone is shown.

[0062] like Figure 1A and Figure 1B As shown, the display device 1000 includes a display module 1 and a cover plate 2 disposed on the light-emitting side of the display module 1. In the case where the display device 1000 is a foldable display device, the display module 1 includes a support structure 10 and a display panel 30.

[0063] The display panel 30 includes at least two first display portions L1 and at least one second display portion L2, one second display portion L2 is disposed between two adjacent first display portions L1 and connected to the two adjacent first display portions L1, and the second display portion L2 is bendable. The support structure 10 is configured to support the display panel 30, and the support structure 10 is disposed on the backlight side of the display panel 30, and includes at least two first support portions M1 respectively disposed corresponding to the at least two first display portions L1, and at least one second support portion M2 disposed corresponding to the at least one second display portion L2.

[0064] The display panel 30 is flexible. The material of the support structure 10 includes a rigid material, such as stainless steel (SUS), titanium alloy or carbon fiber, etc. The support structure 10 may also include other rigid materials as long as they can support the display panel.

[0065] The first support portion M1 disposed on the backlight side of the first display portion L1 of the display panel 30 is used to support the corresponding first display portion L1. The second support portion M2 includes a folding structure so that the second support portion M2 can be bent, and by bending the second support portion M2, the two first display portions L1 connected on both sides of the second support portion M2 can be overlapped or unfolded, so that the display device 1000 can obtain a folded, unfolded, etc. state.

[0066] For example, Figure 1A , Figure 1B and Figure 2 As shown, the display panel 30 includes two first display parts L1 and one second display part L2, one second display part L2 is arranged between two adjacent first display parts L1 and connected to the two adjacent first display parts L1, and the second display part L2 can be bent. The support structure 10 includes two first support parts M1 respectively arranged corresponding to the two first display parts L1, and one second support part M2 arranged corresponding to the second display part L2. By bending the second display part L2, the display panel 30 can present a bent state, an unfolded state, or a state between the bent state and the unfolded state where the two first display parts L1 have an angle.

[0067] For example, the display panel 30 may also include three first display parts L1 and two second display parts L2, one second display part L2 is arranged between two adjacent first display parts L1 and connected to the two adjacent first display parts L1, and any second display part L2 can be bent. The support structure 10 includes three first support parts M1 respectively arranged corresponding to the three first display parts L1, and two second support parts M2 arranged corresponding to the two second display parts L2. By bending any second display part L2, the two first display parts L1 connected to the bent second display part L2 can present a bent state, an unfolded state, or a state between the bent state and the unfolded state where the two first display parts L1 have an angle; by bending the two second display parts L2, the display panel 30 can present a three-fold state, an unfolded state, or a state between the bent state and the unfolded state.

[0068] For example, the display panel 30 may further include a plurality of first display portions L1 and a plurality of second display portions L2, one second display portion L2 is disposed between two adjacent first display portions L1 and connected to the two adjacent first display portions L1, and any second display portion L2 may be bent. The support structure 10 includes a plurality of first support portions M1 disposed corresponding to the plurality of first display portions L1, and a plurality of second support portions M2 disposed corresponding to the plurality of second display portions L2, without limitation.

[0069] The cover plate 2 is a transparent cover plate, which is configured to support and protect the display module 1 and ensure that the display module 1 can still maintain a good display effect when it is hit or scratched. The cover plate 2 is also flexible to match the folding and unfolding states of the display module 1.

[0070] In some embodiments, the cover plate 2 includes at least one layer of organic material.

[0071] For example, reference Figure 1A The cover plate 2 is a single layer, and the material of the single layer cover plate may include polyimide (PI for short) or polyethylene terephthalate (PET for short).

[0072] For example, reference Figure 1B The cover plate 2 can also be multi-layered. When the cover plate 2 is multi-layered, it includes: a first cover plate sublayer 201, a cover plate adhesive layer 202 and a second cover plate sublayer 203 stacked in sequence, and the second cover plate sublayer 203 is arranged on a side away from the display module 1.

[0073] For example, the material of the first cover plate sublayer 201 includes: polyimide (PI for short) or ultra-thin flexible glass.

[0074] For example, the material of the cover adhesive layer 202 includes: optically clear adhesive (OCA) which is colorless, transparent, high transmittance and good bonding strength. The optical adhesive has high bonding strength and high transparency and will not affect the display effect of the display module.

[0075] For example, the material of the second cover plate sub-layer 203 includes: polyethylene terephthalate (PET for short).

[0076] At present, in order to achieve a higher screen-to-body ratio for the display device 1000, a through hole may be provided in the display area of ​​the display device 1000, and then a camera or other device may be provided in the through hole. Figure 3 , Figure 3 for Figure 2The enlarged view of the display device 1000 at the dotted circle S in FIG. 1 shows the display device 1000 including a display area Q1, a hole edge area Q2 and a through hole area Q3. The display area Q1 is provided with sub-pixels for displaying images. The camera is located in the through hole area Q3. The hole edge area Q2 is located between the display area Q1 and the through hole area Q3 and surrounds the through hole area Q3. The hole edge area Q2 is a ring around the through hole area Q3. It can be understood that for the foldable display device 1000, each first display portion L1 includes a portion of the display area Q1, and each second display portion L2 also includes a portion of the display area Q1.

[0077] The hole edge area Q2 is a transition area between the display area Q1 and the through hole area Q3. No sub-pixels are set in the hole edge area Q2, so it cannot be used for display. The hole edge area Q2 is used to set relevant structures for encapsulating the display area Q1, such as a barrier dam, to prevent water and oxygen from entering the display area Q1 through the through hole area Q3 and corroding the sub-pixels, circuits, signal lines and other structures in the display area Q1.

[0078] Understandably, Figure 3 In the figure, the hole edge area Q2 is a circular ring as an example for illustration, however, the shape of the hole edge area Q2 is not limited to a ring, it can be any shape, and its boundary does not necessarily extend straight or smoothly, and its boundary can extend in an irregular shape. In some embodiments, the shape of the hole edge area Q2 depends on the shape of the through hole area Q3. When the through hole area Q3 is circular, the hole edge area Q2 is a circular ring. When the through hole area Q3 is rectangular, the hole edge area Q2 is a square frame. When the through hole area Q3 is a racetrack, the hole edge area Q2 is a racetrack.

[0079] Combined with reference Figure 2 , Figure 3 and Figure 4 , Figure 4 for Figure 3 A cross-sectional view of the local structure of the display device along the AA direction in the display module 1, wherein in the display module 1, at least one first display portion L1 of the display panel 30 has a first through hole H1 penetrating the first display portion L1, and at least one first support portion M1 of the support structure 10 has a second through hole H2 penetrating the first support portion M1, and the first through hole H1 and the second through hole H2 are interconnected for placing the camera of the display device 1000.

[0080] In order to avoid interference between the camera and the support structure 10, the boundary of the second through hole H2 is set outside the boundary of the first through hole H1, that is, the first display part L1 of the display panel 30 extends outward compared with the first support part M1 of the support structure 10. However, since the support structure 10 generally adopts a rigid structure, the cover plate 2 in the display device 1000 is a flexible cover plate, and the display panel 30 is also a flexible panel. The mechanical properties of the flexible cover plate are poor, and the flexible cover plate cannot protect the display panel. When the display panel 30 is squeezed by the outside or dropped, since the bottom of the first display part L1 of the extended display panel 30 is not supported by the support structure 10, the display panel 30 will be concentratedly compressed at the edge of the second through hole H2 of the support structure 10, resulting in stress concentration and then causing the display panel 30 to rupture, and finally causing black spots to appear on the display device 1000, such as Figure 3 Therefore, the mechanical ability of the display module 1 to resist extrusion and impact needs to be urgently addressed.

[0081] To solve the above technical problems, refer to Figure 5 In some embodiments, a display module 1 is provided. The display module 1 includes: a display panel 30 and a support structure 10. The display panel 30 is foldable, and at least one first display portion L1 thereof has a first through hole H1 penetrating the first display portion L1. The support structure 10 is foldable, and at least one first support portion M1 thereof has a second through hole H2 penetrating the first support portion M1, and the first through hole H1 and the second through hole H2 are interconnected; the boundary of the first through hole H1 is located outside the boundary of the second through hole H2, or the boundary of the first through hole H1 coincides with the boundary of the second through hole H2.

[0082] The display module 1 provided by the embodiment of the present disclosure is configured such that the boundary of the first through hole H1 is located outside the boundary of the second through hole H2, or the boundary of the first through hole H1 coincides with the boundary of the second through hole H2. Thus, compared with the case where the boundary of the second through hole H2 is located outside the boundary of the first through hole H1, when the display panel 30 is subjected to external compression or drop impact, the support structure 10 can fully support the display panel 30, thereby avoiding stress concentration at the edge of the second through hole H2 of the support structure 10 and the display panel 30, which may cause the display panel 30 to rupture, thereby improving the mechanical ability of the display module 1 to resist compression and impact.

[0083] It can be understood that the size of the second through hole H2 of the support structure 10 can be set based on the size required to avoid interference with the camera. On this basis, the size of the first through hole H1 of the display panel 30 needs to be larger than or equal to the size of the second through hole H2 of the support structure 10.

[0084] The shape of the first through hole H1 in the embodiment of the present disclosure is circular, but not limited thereto. The shape of the first through hole H1 may also be rectangular, elliptical or other irregular shapes.

[0085] The shape of the second through hole H2 in the embodiment of the present disclosure is circular, but not limited thereto. The shape of the second through hole H2 may also be rectangular, elliptical or other irregular shapes.

[0086] In the display module 1 provided by the embodiment of the present disclosure, when the boundary of the first through hole H1 is located outside the boundary of the second through hole H2, the first through hole H1 and the second through hole H2 can be of the same shape or different shapes, as long as the boundary of the first through hole H1 is located outside the boundary of the second through hole H2.

[0087] In some embodiments, reference Figure 5 The display panel 30 includes a display substrate 31 and a black matrix layer 32 disposed on the display substrate 31. The black matrix layer 32 is located in the display area Q1 and has a plurality of openings in the display area Q1. A plurality of color resists are disposed in a one-to-one correspondence in the plurality of openings. The plurality of color resists include color resists of a plurality of colors so that light having the same color as the color resists can pass through. The black matrix layer 32 is located between any adjacent color resists and is used to prevent color confusion between sub-pixels in the display substrate 31 and increase contrast. The black matrix layer 32 and the plurality of color resists form a color filter to reduce reflection of ambient light in the display panel 30 and improve the display quality of the display panel 30. The color filter can be disposed on the encapsulation layer of the display panel 30, so the color filter is also called a COE (color film on encapsulation) structure.

[0088] Based on the above structure, in this embodiment, the black matrix layer 32 is further extended to the hole edge area Q2 to block the hole edge area Q2 to prevent the light of the sub-pixel of the display area Q1 from being emitted through the hole edge area Q2 and causing light leakage. In this embodiment, the black matrix layer 32 is directly used to cover the hole edge area Q2 to block the light in the hole edge area Q2. Compared with setting a film layer for shading in the hole edge area Q2 separately, since there is no need to consider the fitting accuracy of the shading film layer and the display panel, and an additional shading area is reserved in the shading film layer, a narrow frame can be achieved; and process steps are saved.

[0089] In other embodiments, reference Figure 6 The display panel 30 includes a display substrate 31 and a polarizer 33 disposed on the display substrate 31, and the first through hole H1 also penetrates the polarizer 33. The first display portion L1 includes a display area Q1 and a hole edge area Q2, and the hole edge area Q2 is located between the display area Q1 and the first through hole H1 and surrounds the first through hole H1.

[0090] In order to block the light of the display panel 30 in the hole edge area Q2, the display panel 30 further includes a second light shielding layer 50, which is disposed on the side of the polarizer 33 away from the display substrate 31 and covers the hole edge area Q2. The polarizer 33 is used to reduce the reflection of external ambient light in the display panel and improve the display quality of the display panel 30.

[0091] On this basis, when the boundary of the first through hole H1 is located outside the boundary of the second through hole H2, when the light from the external environment is irradiated from the light exiting side of the display panel 30 to the through hole area Q3, the portion of the first supporting portion M1 of the supporting structure 10 extending outward from the first display portion L1 of the display panel 30 will reflect the light from the external environment. When the display panel 30 includes a display substrate 31 and a black matrix layer 32 disposed on the display substrate 31, the black matrix layer 32 of the hole edge area Q2 will absorb a portion of the light from the external environment and will not reflect it out. When the display panel 30 includes a display substrate 31 and a polarizer 33 disposed on the display substrate 31, the display panel 30 also includes a When the polarizer 33 is on the side away from the display substrate 31 and covers the second light-shielding layer 50 in the hole edge area Q2, the second light-shielding layer 50 in the hole edge area Q2 will absorb a portion of the light from the external environment and will not reflect it out. Therefore, a visual chromatic aberration problem of the front hole area will be introduced on the light-emitting side of the display module 1, that is, there is a color difference between the portion of the hole edge area Q2 covered by the black matrix layer 32 and the portion extending from the first display portion L1 of the display panel 30 compared with the first support portion M1 of the supporting structure 10, or there is a color difference between the portion of the hole edge area Q2 covered by the second light-shielding layer 50 and the portion extending from the first display portion L1 of the display panel 30 compared with the first support portion M1 of the supporting structure 10.

[0092] To solve the above problems, in some embodiments, reference Figure 7 , at the first through hole H1, part of the first support part M1 protrudes compared to the first display part L1; the display module 1 also includes a first light shielding layer 40, which is arranged between the first display part L1 and the first support part M1, and in the orthographic projection to the reference plane, the first light shielding layer 40 at least covers the part of the first support part M1 protruding compared to the first display part L1. The reference plane is the plane where the surface of the display panel 30 away from the support structure 10 is located. In this arrangement, when the light of the external environment is irradiated from the light-emitting side of the display panel 30 to the through hole area Q3, the part of the first support part M1 protruding compared to the first display part L1 will not reflect the light of the external environment or only reflect a small part of the light, thereby improving the visual color difference problem of the front surface edge area Q2 of the light-emitting side of the display module 1.

[0093] In some embodiments, the black matrix layer 32 and the first light shielding layer 40 have the same absorption coefficient. This arrangement is conducive to improving the visual color difference problem of the front surface area introduced on the light output side of the display module 1. Exemplarily, the color of the first light shielding layer 40 can be the same as or similar to the color of the black matrix layer 32. For example, the material of the first light shielding layer 40 can be the same as that of the black matrix layer 32, for example, both are black ink.

[0094] Continue to refer Figure 7 The display module 1 further includes: an adhesive layer 20 disposed between the first display portion L1 and the first support portion M1 , and the adhesive layer 20 is configured to bond the support structure 10 and the display panel 30 .

[0095] Exemplarily, the adhesive layer 20 includes a first sub-adhesive layer 21, a second sub-adhesive layer 22, and a substrate layer 23 located between the first sub-adhesive layer 21 and the second sub-adhesive layer 22; wherein the substrate layer 23 includes a polyimide (PI) substrate layer or a polyethylene terephthalate (PET) substrate layer.

[0096] Exemplarily, the adhesive layer may also be a single layer, and the material of the single layer of adhesive layer includes optically clear adhesive (OCA for short).

[0097] The adhesive layer 20 has a third through hole H3 penetrating the adhesive layer 20, so that the first through hole H1, the third through hole H3 and the second through hole H2 form a connected accommodation space. Exemplarily, the boundary of the third through hole H3 coincides with the boundary of the first through hole H1 to avoid interference with the camera.

[0098] In some embodiments, continue to refer to Figure 7 In a case where the boundary of the third through hole H3 coincides with the boundary of the first through hole H1 , the first light shielding layer 40 may be provided at least on the surface of the first supporting portion M1 facing the first display portion L1 .

[0099] For example, reference Figure 7 The first light shielding layer 40 only covers the surface of the portion of the first supporting portion M1 of the supporting structure 10 that extends out from the first display portion L1 of the display panel 30, so that the first light shielding layer 40 and the black matrix layer 32 extending to the hole edge area Q2 are combined to jointly block the hole edge area Q2.

[0100] For example, reference Figure 8The first light-shielding layer 40 covers the surface of the portion of the first supporting portion M1 of the supporting structure 10 that extends out from the first display portion L1 of the display panel 30, and extends in a direction away from the second through hole H2. That is, in the orthographic projection onto the reference plane, the first light-shielding layer 40 overlaps with a portion of the black matrix layer 32 located in the hole edge area Q2, thereby ensuring that no light leaks from the junction of the first light-shielding layer 40 and the black matrix layer 32, thereby ensuring that the hole edge area Q2 is completely blocked.

[0101] For example, reference Fig. 9 , the first light shielding layer 40 also covers the side walls of the first through hole H1 and the side walls of the third through hole H3. When there is an angle between the line of sight and the normal of the reference plane (the reference plane is the plane where the surface of the display panel 30 away from the support structure 10 is located), that is, in the case of a side viewing angle, since the side walls of the first through hole H1 and the side walls of the third through hole H3 are covered by the first light shielding layer 40, the color difference of the display module in the side viewing angle can also be improved.

[0102] For example, reference Fig.10 , the first light shielding layer 40 also covers the side wall of the second through hole H2. When there is an angle between the line of sight and the normal of the reference plane, since the side wall of the first through hole H1, the side wall of the second through hole H2 and the side wall of the third through hole H3 are all covered by the first light shielding layer 40, the color difference of the display module at a side viewing angle can be further improved.

[0103] In the case where the first light shielding layer 40 covers the side walls of the first through hole H1, the second through hole H2 and the third through hole H3, the steps of forming the first light shielding layer 40 may be: Fig.11 After the support structure 10 is disposed on the backlight side of the display panel 30, a first light shielding layer 40 is formed on the side wall of the second through hole H2, the surface of the support structure 10 close to the display panel 30, the side wall of the third through hole H3, and the side wall of the first through hole H1 by a spraying process.

[0104] Exemplarily, a spraying device P is used for spraying, and the sprayed material includes ink.

[0105] It can be understood that when the first light-shielding layer 40 also covers the side walls of the first through hole H1 and the side walls of the third through hole H3, the above method can also be used to form the first light-shielding layer 40. The difference is that it is only necessary to avoid spraying ink on the side walls of the second through hole H2 by adjusting the spraying angle, blocking the side walls of the second through hole H2, etc.

[0106] In addition, continue to refer to Fig. 9 and Fig.10In some possible designs, the first light shielding layer 40 covers the side wall of the first through hole H1 and is connected to the black matrix layer 32. This can avoid the black matrix layer 32 and the first light shielding layer 40 from forming a gap at the side wall of the first through hole H1, thereby preventing light from the display substrate 31 from leaking out of the gap.

[0107] In other embodiments, reference Fig.12 In the orthographic projection onto the reference plane, the boundary of the third through hole H3 is between the boundary of the first through hole H1 and the boundary of the second through hole H2, and the first light shielding layer 40 is at least provided on the surface of the first supporting portion M1 facing the first display portion L1.

[0108] For example, the first light shielding layer 40 may only cover the surface of the portion of the first support portion M1 of the support structure 10 that protrudes from the first display portion L1 of the display panel 30. Fig.12 The first light shielding layer 40 covers the surface of the portion of the first support portion M1 that extends outward from the first display portion L1, and extends in a direction away from the second through hole H2, so that in the orthographic projection onto the reference plane, the first light shielding layer 40 overlaps with the black matrix layer 32. This ensures that there is no light leakage at the junction of the first light shielding layer 40 and the black matrix layer 32, and ensures that the hole edge area Q2 is completely shielded.

[0109] For example, reference Fig.13 The first light shielding layer 40 covers the surface of the portion of the first support portion M1 of the support structure 10 extending from the first display portion L1 of the display panel 30, and also covers the surface of the portion of the adhesive layer 20 extending from the first display portion L1 of the display panel 30 away from the first support portion M1 of the support structure 10. In this way, it is possible to prevent the light of the side view from being emitted from between the black matrix layer 32 and the first light shielding layer 40 disposed on the surface of the support structure 10, thereby preventing light leakage.

[0110] In other embodiments, in the orthographic projection onto the reference plane, the boundary of the third through hole H3 coincides with the boundary of the second through hole H2 , and the first shading layer 40 is disposed on the surface of the adhesive layer 20 close to or away from the support structure 10 , or inside the adhesive layer 20 .

[0111] For example, reference Fig.14 , the first light shielding layer 40 is disposed on the surface of the adhesive layer 20 close to the supporting structure 10 .

[0112] For example, reference Fig.15 The first light shielding layer 40 is disposed on the surface of the adhesive layer 20 away from the supporting structure 10 .

[0113] For example, reference Fig.16 , Fig.17 and Fig.18 , the first light shielding layer 40 is disposed inside the adhesive layer 20 .

[0114] The adhesive layer 20 includes a first sub-adhesive layer 21, a second sub-adhesive layer 22, and a base material layer 23 located between the first sub-adhesive layer 21 and the second sub-adhesive layer 22. When the first light shielding layer 40 is disposed inside the adhesive layer 20, the first light shielding layer 40 is disposed between the first sub-adhesive layer 21 and the base material layer 23, and / or between the second sub-adhesive layer 22 and the base material layer 23.

[0115] For example, refer to Fig.16 The first light shielding layer 40 is disposed between the first sub-glue layer 21 and the base material layer 23 .

[0116] For example, refer to Fig.17 The first light shielding layer 40 is disposed between the second sub-glue layer 22 and the base material layer 23 .

[0117] For example, refer to Fig.18 A first light shielding layer 40 is disposed between the first sub-glue layer 21 and the base material layer 23 , and between the second sub-glue layer 22 and the base material layer 23 .

[0118] In addition, in some possible designs, reference Fig.19 , the base material layer 23 in the adhesive layer 20 includes a light shielding material, which serves as the first light shielding layer 40. That is, the base material layer 23 is not only used as a carrier of the first sub-adhesive layer 21 and the second sub-adhesive layer 22, but also reused as the first light shielding layer 40. This can avoid adding an extra layer of structure, which is conducive to reducing the thickness of the display module.

[0119] In the above design, the light shielding material can be added to the substrate material in a solvent state during the preparation of the adhesive layer 20, and then the solvent is coated and cured to form a substrate layer with a light shielding effect. For example, the added light shielding material can be carbon powder.

[0120] When the display panel 30 includes a display substrate 31, a polarizer 33 arranged on the display substrate 31, and a second shading layer 50, in order to solve the problem of visual chromatic aberration of the front surface area introduced on the light-emitting side of the display module 1, a first shading layer is set in the display module. The situations in which the first shading layer may be set are described above and will not be repeated here.

[0121] In some embodiments, the second light shielding layer 50 has the same light absorption coefficient as the first light shielding layer 40. This arrangement is beneficial to improving the visual chromatic aberration problem of the front surface area introduced on the light exiting side of the display module 1.

[0122] Exemplarily, the color of the first light shielding layer 40 may be the same as or similar to the color of the second light shielding layer 50. For example, the material of the first light shielding layer 40 may be the same as the material of the second light shielding layer 50, such as black ink.

[0123] refer to Fig. 20An embodiment of the present disclosure further provides a display device 1000 , which includes a display module 1 , a camera 4 and a cover plate 2 .

[0124] The boundary of the first through hole H1 penetrating the display panel 30 in the display module 1 is located outside the boundary of the second through hole H2 penetrating the support structure 10, or the boundary of the first through hole H1 coincides with the boundary of the second through hole H2. In this way, when the display device 1000 is subjected to external extrusion or drop impact, the support structure 10 can fully support the display panel 30, avoiding stress concentration at the edge of the second through hole H2 of the support structure 10 and the display panel 30, which may cause the display panel 30 to rupture, thereby improving the mechanical ability of the display device 1000 to resist extrusion and impact.

[0125] It should be noted that the display module 1 includes the display module provided by any of the previous embodiments, which will not be described in detail here.

[0126] The camera 4 is disposed in the first through hole H1 and the second through hole H2.

[0127] The cover plate 2 is disposed on the light-emitting side of the display module 1 and covers the camera 4. The cover plate 2 is a flexible cover plate, and the material and function of the cover plate 2 can refer to the corresponding description above, which will not be repeated here.

[0128] In some embodiments, the display device 1000 further includes: an optical adhesive layer 3 disposed between the cover plate 2 and the display module 1 , and the optical adhesive layer 3 is configured to bond the display module 1 and the cover plate 2 .

[0129] Exemplarily, the optical adhesive layer 3 is colorless, transparent, high transmittance, and good bonding strength optical adhesive (Optically Clear Adhesive, abbreviated as: OCA). The optical adhesive has high bonding strength and high transparency and will not affect the display effect of the display module.

[0130] The optical adhesive layer 3 has a fourth through hole H4 penetrating the optical adhesive layer 3, and the fourth through hole H4 is connected to the first through hole H1. This arrangement can not only ensure sufficient bonding between the cover plate 2 and the display module 1, but also prevent the optical adhesive layer 3 from blocking the camera 4, thereby improving the imaging quality of the camera.

[0131] The above is only a specific embodiment of the present disclosure, but the protection scope of the present disclosure is not limited thereto. Any changes or substitutions that can be thought of by any person skilled in the art within the technical scope disclosed in the present disclosure should be included in the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure should be based on the protection scope of the claims.
