The flexible display screen can fold the side edge of the flexible display module to the backlight side, thereby reducing the frame of the display module and the display device, and effectively improving the screen-to-body ratio.

[0003] In the related art, in order to protect the bending area of the display panel and improve the stress of the bending area, a protective layer is usually coated on the surface of the bending area.

It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0032] In the following description, a large number of specific details are set forth in order to facilitate a thorough understanding of the present disclosure, but the present disclosure can also be implemented in other manners different from those described herein; obviously, the embodiments described in the specification are only a part of the embodiments of the present disclosure, and not all the embodiments.

[0033] In combination with the background section, as shown in Figure 1 The side surface of the protective layer 3 is in contact with the side surface of the polarizing component 2, when the display panel 1 is in the bent state, the polarizing component 2 will slip relative to the display panel 1, the polarizing component 2 and the protective layer 3 extrude each other, and additional stress is generated, which is easy to cause the protective layer 3 to fall off or display abnormality and other problems. As shown in Figure 2 The protective layer 3 is spaced apart from the edge of the polarizing component 2 by a distance, plus the limitation of the preparation process of the protective layer 3, the flow leveling distance of the protective layer 3 is longer, and the limitation of the coating precision of the protective layer 3 and the bonding precision of the polarizing component 2, which leads to a larger frame of the display screen, and cannot meet the requirement of narrow frame, and the area of the display panel 1 not covered by the protective layer 3 is easy to be damaged by static electricity, resulting in failure of the display screen.

[0034] In order to solve the above technical problems, the present disclosure provides a display module and a display device, the display module comprises: a display panel, the display panel comprises a first area, a bending area and a second area; wherein the bending area connects the first area and the second area; the first area comprises a first sub-area, a second sub-area and a third sub-area, the second sub-area is located between the first sub-area and the third sub-area, and the third sub-area is connected with the bending area; a polarizing component is located on the light exit side of the first area and covers the first sub-area; a protective layer is located on the same side of the display panel as the polarizing component, and the protective layer covers the third sub-area, the bending area and part of the second area; a stretchable module covers the second sub-area, the stretchable module is located between the polarizing component and the protective layer, and is connected with the polarizing component and the protective layer, and the stretchable module is stretched when the bending area is bent, and is used to release the slip amount of the polarizing component. Thus, the protective layer is connected with the polarizing component through the stretchable module, the flow leveling length of the protective layer is cancelled, the frame width of the display module can be effectively reduced, the stretchable module is stretched when the bending area is in the bent state, the slip amount of the polarizing component relative to the display panel can be released, the mutual extrusion of the polarizing component and the protective layer is avoided, and the stretchable module can also protect the area not covered by the protective layer, preventing the display panel in the area from being damaged by static electricity.

[0035] The display module and the display device provided by the embodiments of the present disclosure will be exemplarily described below in combination with the drawings.

[0036] In some embodiments, such as Figure 3 The diagram shown is a structural schematic of a display module provided in an embodiment of this disclosure. (Refer to...) Figure 3 The display module 10 includes: a display panel 1, a polarizing component 2, a protective layer 3, and a telescopic module 4; wherein, the display panel 1 includes a first region 11, a bending region 12, and a second region 13; the bending region 12 connects the first region 11 and the second region 13; the first region 11 includes a first sub-region 111, a second sub-region 112, and a third sub-region 113, the second sub-region 112 is located between the first sub-region 111 and the third sub-region 113, and the third sub-region 113 is connected to the bending region 12; the polarizing component 3... Component 2 is located on the light-emitting side of the first zone 11 and covers the first sub-zone 111; the protective layer 3 and the polarizing component 2 are located on the same side of the display panel 1, and the protective layer 2 covers the third sub-zone 113, the bending zone 12 and part of the second zone 13; the telescopic module 4 covers the second sub-zone 112, and the telescopic module 4 is located between the polarizing component 2 and the protective layer 3 and is connected to the polarizing component 2 and the protective layer 3. The telescopic module 4 is stretched when the bending zone 12 is bent, which is used to release the sliding amount of the polarizing component 2.

[0037] The display panel 1 is a flexible display panel, which includes a first area 11, a bending area 12 connected to the first area 11, and a second area 13 located on the side of the bending area 12 away from the first area 11. The bending area 12 bends toward the backlight side of the first area 11 so that the second area 13 is folded to the backlight side of the first area 11, thereby enabling the display device using the display module 10 to have a smaller bezel width, which is beneficial to achieving a narrow bezel display of the display device.

[0038] An adhesive layer is provided on the side surface of the polarizing component 2 that is attached to the first sub-region 111. The adhesive layer has high viscosity and low modulus characteristics, such as optically clear adhesive (OCA) and pressure-sensitive adhesive (PSA). The polarizing component 2 includes a polarizer, a polarizing film, and other polarizing components known to those skilled in the art, which are not limited herein. The polarizing component 2 is used to effectively resist ambient light and reduce interference with the display, but is not limited thereto. For example, when external ambient light is incident on the display panel 1, the polarizing component 2 can absorb part of the external ambient light, preventing the external ambient light from being reflected by the metal lines inside the display panel 1, thereby reducing reflectivity and improving the contrast of the display panel 1.

[0039] The protection layer 3 includes ultraviolet rays (UV) glue or bending protection layer (BPL) glue. The protection layer 3 is located on the side of the bending area 12 facing the light-emitting side of the display panel 1, and covers at least the bending area 12 to protect the fan-out wires of the bending area 12 and avoid line breakage of the bending area 12 during bending. In addition, in order to ensure the stability of the adhesion of the protection layer 30, the protection layer 3 can also cover part of the first area 11 (i.e., the third sub-area 113) and part of the second area 13.

[0040] The stretchable module 4 is arranged on the side of the polarizing component 2 close to the bending area 12, and the stretchable module 4 covers the second sub-area 112. The stretchable module 4 is made of a material with high elasticity and low Young's modulus, which is easy to be compressed or stretched. As shown in Figures 3-4 When the bending area 12 of the display panel 1 is in the bent state, the right edge of the stretchable module 4 is pulled to the right by the protection layer 3, so that the stretchable module 4 is in a stretched state to release the sliding amount of the polarizing component 2 relative to the display panel 1, and avoid the mutual extrusion of the polarizing component 2 and the protection layer 3. Figure 2 Compared with the display module shown in

[0041] The display module 10 provided by the embodiments of the present disclosure can effectively reduce the frame width of the display module 10 by arranging the stretchable module 4 between the protection layer 3 and the polarizing component 2, and connecting the protection layer 3 and the polarizing component 2 through the stretchable module 4, canceling the flow length of the protection layer 3. At the same time, the stretchable module 4 is stretched when the bending area 12 is in the bent state, which can release the sliding amount of the polarizing component 2 relative to the display panel 1, avoid the mutual extrusion of the polarizing component 2 and the protection layer 3, and the stretchable module 4 can also protect the area not covered by the protection layer 3, preventing the display panel 1 in this area from being electrostatically shocked.

[0042] In some embodiments, when the stretchable module 4 is fixed between the polarizing component 2 and the protection layer 3, the stretchable module 4 can be fixed in a free state, or the stretchable module 4 can be fixed in a compressed state.

[0043] As shown in Figures 5-6 When the bending area 12 of the display panel 1 is in the flat state, the stretchable module 4 is in the free state, neither stretched nor compressed, and its length is the original length.

[0044] As shown in Figure 5 andFigure 7 As shown, when the bending area 12 of the display panel 1 is in the flattened state, the stretchable module 4 is compressed. In this way, when the bending area 12 is bent, the stretching length of the stretchable module 4 is reduced.

[0045] In some embodiments, as shown in any one of Figure 4 , 6 and 7, the stretchable module 4 is a hollow structure.

[0046] In some embodiments, the stretchable module 4 is a hollow structure, which is easy to be stretched and compressed. Figure 4 , 6 and 7 only exemplarily show that the stretchable module 4 is a hollow sphere, and the stretchable module 4 can also be set to other hollow shapes known to those skilled in the art, such as a hollow cuboid or a hollow cylinder, and the like, and the embodiments of the present disclosure do not limit the shape of the stretchable module 4.

[0047] In some embodiments, as shown in Figure 3 or Figure 5 , along the direction in which the stretchable module 4 points to the polarizing component 2, the width W1 of the stretchable module 4 satisfies: 60 μm≤W1≤120 μm.

[0048] In some embodiments, the width W1 of the stretchable module 4 is the width of the stretchable module 4 in the free state. For example, the width W1 of the stretchable module 4 in the free state is 60 μm, if the stretchable module 4 is fixed between the polarizing component 2 and the protective layer 3 in the compressed state, the width of the stretchable module 4 is 30 μm, and the compression ratio is 2:1; when the bending area 12 is bent, the stretchable module 4 is in the stretched state, and at this time the width of the stretchable module 4 is 100 μm.

[0049] It should be noted that the embodiments of the present disclosure only exemplarily show that the stretchable module 4 is fixed between the polarizing component 2 and the protective layer 3 in the compressed state, and the compression ratio is 2:1, but it does not constitute a limitation on the display module 10 provided by the embodiments of the present disclosure. In other embodiments, the compression ratio of the stretchable module 4 can be set according to the needs, for example, the compression ratio is 1.5:1 or 3:1, which is not limited herein.

[0050] In this way, the protective layer 3 is in contact with the stretchable module 4, and is connected with the polarizing component 2 through the stretchable module 4, which cancels the flow length of the protective layer 3, and effectively reduces the frame width of the display module 10. Exemplarily, compared with the display module shown in Figure 2 , the frame width of the display module 10 is reduced by 300 μm-500 μm.

[0051] In some embodiments, the stretchable module 4 includes foam.

[0052] In this embodiment, the foam has the characteristics of elasticity, light weight, rapid pressure-sensitive fixing, flexible bending, ultra-thin size, and reliable performance. In other embodiments, other foaming materials known to those skilled in the art can also be used to prepare the telescopic module 4, and are not limited here.

[0053] In some embodiments, such as Figure 8 or Figure 9 As shown, the display module 10 also includes an optical adhesive layer 5 and a cover plate 6; wherein the optical adhesive layer 5 is located on the side of the polarizing component 2 away from the first region 11; and the cover plate 6 is located on the side of the optical adhesive layer 5 away from the polarizing component 2.

[0054] The cover plate 6 is located on the light-emitting side of the first zone 11 and is bonded to the polarizing component 2 via the optical adhesive layer 5. The cover plate 6 has high light transmittance and high hardness, thus protecting the display panel 1 without affecting the display, but it is not limited to this function.

[0055] The optical adhesive layer 5 at least partially covers the surface of the polarizing component 2 facing away from the display panel 1. The optical adhesive layer 5 has high light transmittance, reducing the impact on the display effect of the first area 11, but is not limited thereto.

[0056] In other embodiments, the cover plate 6 may also be bonded to the display panel 1 by other adhesive material layers known to those skilled in the art, such as optically clear resin (OCR), which is not limited herein.

[0057] In some embodiments, such as Figure 8 As shown in Figure 9, in the display module 10, along the direction from the polarizing component 2 to the telescopic module 4, the distance D1 between the edge of the optical adhesive layer 5 and the edge of the polarizing component 2 satisfies: 70μm≤D1≤100μm.

[0058] Since the optical adhesive layer 5 has a certain adhesive properties, this design ensures that the optical adhesive layer 5 will not come into contact with the telescopic module 4 after sliding, thereby avoiding adhesion between the optical adhesive layer 5 and the telescopic module 4.

[0059] In some embodiments, such as Figure 9 As shown, the display module 10 also includes an ink layer 7; the ink layer 7 is located on the side of the cover plate 6 near the optical adhesive layer 5, the ink layer 7 partially overlaps with the optical adhesive layer 5, and the ink layer 7 covers the telescopic module 4 and the bending area 12.

[0060] The ink layer 7 can be applied to the inner surface of the cover plate 6 by spraying, flow coating, scraping, or transfer printing. The inner surface of the cover plate 6 is the side of the cover plate 6 that is bonded to the optical adhesive layer 5. In the thickness direction of the display module 10, the ink layer 7 and the optical adhesive layer 5 at least partially overlap, and the ink layer 7 is located in the border area of ​​the cover plate 6, covering part of the polarizing component 2, the telescopic module 4, and the bending area 12. With this arrangement, the ink layer 7 blocks the non-display areas such as the telescopic module 4 and the bending area 12.

[0061] In some embodiments, as shown in 9, in the display module 10, the ink layer 7 and the optical adhesive layer 5 partially overlap, and along the direction from the polarizing component 2 to the telescopic module 4, the width W2 of the overlapping area of ​​the ink layer 7 and the optical adhesive layer 5 satisfies: 20μm≤W2≤40μm.

[0062] In some embodiments, such as Figures 10-14 As shown in any of the figures, the display module 10 also includes: a first back plate 81 and a second back plate 82; wherein, the first back plate 81 is located on the side of the first region 11 away from the polarizing component 2; and the second back plate 82 is located on the side of the second region 13 away from the protective layer 3.

[0063] The materials of the first backplate 81 and the second backplate 82 include polyethylene terephthalate (PET).

[0064] like Figure 14 As shown, when the second region 13 is not bent to the backlight side of the first region 11, that is, when the display panel 1 is in a flat state, the first back plate 81 is located on the side of the first region 11 away from the polarizing component 2, and the second back plate 82 is located on the side of the second region 13 away from the protective layer 3. Figures 10-13 As shown, when the second area 13 bends to the backlight side of the first area 11, the first back plate 81 and the second back plate 82 are opposite each other, and the first back plate 81 and the second back plate 82 are flush with the end of the bending area 12. Along the direction from the polarizing component 2 to the telescopic module 4, the width of the first back plate 81 is greater than the width of the first area 11 of the display panel 1, and the first back plate 81 is used to support the area of ​​the bending area 12 near the first area 11. The width of the second back plate 82 is greater than the width of the second area 13 of the display panel 1, and the second back plate 82 is used to support the area of ​​the bending area 12 near the second area 13.

[0065] As the second area 13 of the display panel 1 is bent to the backlight side of the first area 11, the area of the bending area 12 close to the first area 11 is subjected to a downward bending force, and the area of the bending area 12 close to the second area 13 is subjected to an upward bending force, at this time, the first back plate 81 and the second back plate 82, due to their greater rigidity, can provide a supporting force to the corresponding area in the opposite direction of the bending force to avoid the display panel 1 in the area from collapsing and deforming to cause the circuit in the area to break.

[0066] In some embodiments, as shown in FIG. 1, the display module 10 further comprises a support layer 9; the support layer 9 is located on the side of the first back plate 81 away from the first area 11 of the display panel 1. Figure 10

[0067] In some embodiments, as shown in FIG. 1, the display module 10 further comprises a support layer 9; the support layer 9 is located on the side of the first back plate 81 away from the first area 11 of the display panel 1.

[0068] It should be noted that when the second area 13 is bent to the backlight side of the first area 11, the first back plate 81 is opposite to the second back plate 82, and the ends of the first back plate 81 and the second back plate 82 facing the bending area 12 are flush, then the distance D3 between the side surface of the stretchable module 4 in contact with the protective layer 3 (i.e. the right side surface of the stretchable module 4) and the side surface of the second back plate 82 facing the bending area 12 (i.e. the right side surface of the second back plate 82) also satisfies 70μm≤D3≤100μm.

[0069] In some embodiments, as shown in FIG. 1, the display module 10 further comprises a support layer 9; the support layer 9 is located on the side of the first back plate 81 away from the first area 11 of the display panel 1. Figure 11

[0070] In some embodiments, as shown in FIG. 1, the display module 10 further comprises a support layer 9; the support layer 9 is located on the side of the first back plate 81 away from the first area 11 of the display panel 1.

[0071] In some embodiments, as shown in FIG. 1, the display module 10 further comprises a support layer 9; the support layer 9 is located on the side of the first back plate 81 away from the first area 11 of the display panel 1. Figures 12-14 ​​As shown in any of the figures, in the display module 10, the support layer 9 includes at least one of a foam layer 91, a stainless steel layer 92, and a polyimide layer (PI) 93.

[0072] The foam layer 91 is made of a foaming material such as foam, and has moderate mechanical strength, can be bent, and has weaker bending performance than the display panel 1. The foam layer 91 works together with the first back plate 81 to strengthen the support force on the area of the bending area 12 close to the first area 11, and avoid local stress integration. At the same time, the foam layer 91 has certain air permeability and elasticity, and is arranged between the first back plate 81 and the second back plate 82 to play a role of heat dissipation and buffering.

[0073] The stainless steel layer 92 is beneficial to improve the heat dissipation effect of the circuit board bound to the second area 13 of the display panel 1. In other embodiments, the support layer 9 can also be other metal film layers, such as a copper foil layer, which is not limited here.

[0074] The polyimide layer 93 is used to enhance the overall rigidity of the support layer 9 to increase the compression resistance of the backlight side of the first area 11.

[0075] As shown in the figures, Figure 12 or Figure 13 As shown in the figures, in the display module 10, the support layer 9 is a composite film layer, which includes the foam layer 91 located on the side of the first back plate 81 away from the first area 11, the stainless steel layer 92 located on the side of the second back plate 82 away from the second area 13, and the polyimide layer 93 located between the foam layer 91 and the stainless steel layer 92. In this way, the foam layer 91 is beneficial to ensure that it plays a supporting, buffering, and heat dissipation function in the display module 10; the stainless steel layer 92 is closer to the second area 13 of the display panel 1, which is beneficial to improve the heat dissipation effect of the circuit board bound to the second area 13; and the polyimide layer 93 is used to enhance the overall rigidity of the support layer 9 to increase the compression resistance of the backlight side of the first area 11.
