In order to simplify the disclosure of the present application, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present application. In addition, the present application can repeat reference numbers and / or reference letters in different examples, and this repetition is for the purpose of simplification and clarity, which itself does not indicate the relationship between the various embodiments and / or settings discussed. In addition, the various specific processes and examples of materials provided in the present application, but those of ordinary skill in the art can be aware of the application of other processes and / or the use of other materials.

[0038] See also Figures 1 to 3The display module 100 of the embodiment of the present application includes a panel 10, a transparent adhesive layer 20 and a functional component 30. The panel 10 includes a first side 11 and a second side 12 arranged opposite to each other, and the first side 11 is used to display a picture; the transparent adhesive layer 20 is stacked on the second side 12, and the transparent adhesive layer 20 is used to support the panel 10. The transmittance of the transparent adhesive layer 20 is greater than or equal to 90%; the functional component 30 is arranged on a side of the transparent adhesive layer 20 away from the panel 10, and the light emitted by the functional component 30 can pass through the transparent adhesive layer 20 and the panel 10, and after reflection, it can pass through the panel 10 and the transparent adhesive layer 20 and then be received by the functional component 30.

[0039] See also Figure 4 The electronic device 200 of the embodiment of the present application includes a main body 201 and the display module 100 of the above embodiment, and the display module 100 is arranged on the main body 201 .

[0040] In the display module 100 of the embodiment of the present application, the display module 100 includes a panel 10 and a transparent adhesive layer 20. The transparent adhesive layer 20 and the panel 10 are stacked to support the panel 10 and improve the strength of the display module 100. At the same time, the transparent adhesive layer 20 has a high light transmittance, which allows the light emitted by the functional component 30 to pass through the transparent adhesive layer 20 and the panel 10. At the same time, the light can also pass through the panel 10 and the transparent adhesive layer 20 after reflection to be received by the functional component 30.

[0041] In the related art, the panel of the display screen often uses a 65μm polyimide film (PI) as the back film material. However, the PI back film is yellow in color and has low light transmittance. When a fingerprint reader or distance detector is set under the display screen, the PI back film will cause light loss, which will cause the fingerprint reader and distance detector to fail to detect quickly.

[0042] Specifically, the first side 11 of the panel 10 of the embodiment of the present application can be used to display images, and the second side 12 of the panel 10 can be used to set the transparent adhesive layer 20, so that the transparent adhesive layer 20 can serve as a back film to support the panel 10. At the same time, the transparent adhesive layer 20 has a high light transmittance, and when the light of the functional element passes through the panel 10 and the transparent adhesive layer 20, the transparent adhesive layer 20 will not affect the transmission of the light, thereby ensuring the rapid response of the functional element.

[0043] Exemplarily, the light transmittance of the transparent adhesive layer 20 is greater than or equal to 90%, that is, the amount of light absorbed or reflected in the process of passing through the lens adhesive layer is small, and the light loss is less than 10%. For example, the light transmittance of the transparent adhesive layer 20 can be 90%, 91%, 92%, 93%, 94%, 95%, etc., to ensure that the light can pass through the transparent adhesive layer 20 as much as possible to ensure the rapid response of the functional component 30. In addition, in the embodiments of the present application, the type of the functional component 30 is not limited to meet different needs. For example, the functional component 30 can be a fingerprint identifier, the functional component 30 can also be an infrared sensor, and in the embodiments of the present application, there can also be multiple functional components 30 to achieve different functions.

[0044] Furthermore, the display module 100 may also include a substrate 40, an elastic layer 50, a polarizer 60, an adhesive layer 70 and a cover plate 80, so that the substrate 40, the elastic layer 50, the transparent adhesive layer 20, the panel 10, the polarizer 60, the adhesive layer 70 and the cover plate 80 are stacked in sequence. The polarizer 60 is arranged on the first side 11 of the panel 10, and the elastic layer 50 is arranged on the side of the transparent adhesive layer 20 away from the panel 10. The functional component 30 is arranged below the substrate 40, and the functional component 30 can emit light, which can be emitted through the multi-layer structure of the display module 100 to the environment outside the cover plate 80, and then reflected from the outside of the cover plate 80 through the multi-layer structure of the display module 100 back to the functional component 30, thereby ensuring that the functional component 30 can realize its own function. Of course, the display module 100 may also include other functional layers, which are not specifically limited here.

[0045] In addition, in the embodiments of the present application, the type of the electronic device 200 is not limited. It only needs that the main body 201 of the electronic device 200 can be equipped with the display module 100 of the embodiments of the present application to meet various requirements.

[0046] See also Figures 1 to 3 In some embodiments, the thickness of the transparent adhesive layer 20 is less than or equal to 65 μm. For example, the thickness of the transparent adhesive layer 20 can be 65 μm, 60 μm, 55 μm, 50 μm, 45 μm, 40 μm, 35 μm, 30 μm, etc.

[0047] Thus, the transparent adhesive layer 20 is set within this thickness range, which can ensure the thinning of the entire display module 100, making the display module 100 lighter and thinner, and can ensure the supporting strength, ensure the support of the panel 10, and prevent the display module 100 from being damaged during use.

[0048] In the embodiment of the present application, the thickness of the transparent adhesive layer 20 can be adjusted by itself, and the thickness of the transparent adhesive layer 20 can be less than or equal to 65 μm, so that the entire display module 100 is thinner and lighter, and the transparent adhesive layer 20 can provide good support for the panel 10 .

[0049] See also Figure 1 and Figure 5 In some embodiments, the display module 100 includes a planar portion 13 and a bending portion 14 connected in sequence, and the bending portion 14 can be bent relative to the planar portion 13 to change the display area of ​​the display module 100 .

[0050] In this way, the bending portion 14 can be bent relative to the flat portion 13 to change the display area of ​​the display module 100. In this way, when the user is using it, the bending portion 14 can display the picture flush with the flat portion 13 to achieve a larger display area of ​​the electronic device 200; when the user is not using it, the bending portion 14 can be bent relative to the flat portion 13 to achieve a smaller display area, so that the electronic device 200 is easy to carry.

[0051] The display module 100 in the embodiment of the present application is a flexible display screen that can be bent. For example, the display module 100 in the embodiment of the present application can be an organic light-emitting diode (OLED). The bending portion 14 can be bent relative to the flat portion 13 to change the display area of ​​the display screen and realize different functions.

[0052] Specifically, in one embodiment, the display module 100 may include two planar portions 13, the two planar portions 13 are connected by a bending portion 14, and the areas of the two planar portions 13 are similar. Figure 1 , the part between the two dotted lines of the display module 100 is the bending portion 14, and the left side of the left dotted line and the right side of the right dotted line are the plane portion 13. When the user needs to carry the electronic device 200, the two plane portions 13 can be stacked together through the bending portion 14 so that the two plane portions 13 can overlap. At this time, one of the plane portions 13 is used to display the picture, making the electronic device 200 more compact and easy to carry. When the user needs to use the electronic device 200, the bending portion 14 can be unfolded so that the two plane portions 13 and the bending portion 14 are on the same plane and are used to display the picture at the same time, thereby increasing the display area of ​​the electronic device 200, and the user can have a better display experience.

[0053] Further, in another embodiment, the area of ​​the bent portion 14 may be equal to the area of ​​the planar portion 13. Figure 5, the left side of the dotted line of the display module 100 is the bending portion 14, and the right side of the dotted line is the plane portion 13. When the user needs to carry the electronic device 200, the bending portion 14 can be rolled back into the inside of the electronic device 200. At this time, the plane portion 13 can be used to display the picture, making the electronic device 200 more compact and easy to carry. When the user needs to use the electronic device 200, the bending portion 14 can be pulled out from the inside of the electronic device 200, so that the plane portion 13 and the bending portion 14 are on the same plane and are used to display the picture at the same time, thereby increasing the display area of ​​the electronic device 200, and the user can have a better display experience. Of course, in the implementation manner of the present application, the specific form of the electronic device 200 is not limited. The electronic device 200 can also achieve other forms of changes through the bending portion 14 and the plane portion 13, which are not specifically limited here to meet different needs.

[0054] See also Figures 1 to 3 In some embodiments, the display module 100 includes a folding portion 15 and a connecting portion 16 , the connecting portion 16 is used to connect the driving chip 17 , and the folding portion 15 connects the planar portion 13 and the connecting portion 16 .

[0055] In this way, the folding portion 15 can drive the connecting portion 16 to fold relative to the plane portion 13, so that part of the folding portion 15 and the entire connecting portion 16 can be folded into the inside of the electronic device 200 to avoid occupying the display space of the electronic device 200. Circuits and electronic components can be arranged on the connecting portion 16 for connecting to the driving chip 17, so that the driving chip 17 can drive the panel 10 through the connecting portion 16.

[0056] Specifically, the connecting portion 16 and the folding portion 15 are not used to display the picture. The folding portion 15 can be connected to the plane portion 13 and the connecting portion 16 respectively. The folding portion 15 can be folded into the interior of the electronic device 200. The connecting portion 16 can be connected to components such as the driving chip 17, so that the driving chip 17 can be used to drive the panel 10, so that the display module 100 can be used to display the picture.

[0057] See also Figure 1 In some embodiments, the transparent adhesive layer 20 includes a first area 21, a second area 22 and a third area 23. The first area 21 is arranged corresponding to the planar portion 13, the second area 22 is arranged corresponding to the bending portion 14, and the third area 23 is arranged corresponding to the connecting portion 16. The elastic modulus of the first area 21 and the third area 23 is greater than the elastic modulus of the second area 22.

[0058] In this way, the transparent adhesive layer 20 can be divided into a first region 21, a second region 22 and a third region 23. The first region 21 is arranged on the plane portion 13 to support the plane portion 13, and the first region 21 ensures the strength of the plane portion 13. The second region 22 is arranged on the bending portion 14 so that it can bend with the bending portion 14 while supporting the bending portion 14. The elastic modulus of the second region 22 is small, which can avoid damage during bending. The third region 23 can be arranged at the position of the connecting portion 16 to support and protect the connecting portion 16. In this way, the transparent adhesive layer 20 is not arranged below the folding portion 15, so that the folding portion 15 can drive the connecting portion 16 to fold at a large angle.

[0059] Specifically, in the process of preparing the transparent adhesive layer 20 on the panel 10, different elastic moduli of the transparent adhesive layer 20 can be set for different parts, that is, in the process of the colloid forming the transparent adhesive layer 20, the first area 21 and the third area 23 can be completely cured to ensure sufficient strength to support the plane part 13 and the connecting part 16. The elastic modulus of the second area 22 is relatively small, so that the second area 22 has a certain bending ductility and can be bent together with the bending part 14.

[0060] Furthermore, the display module 100 may also include a curved gasket 90, which is arranged on a side of the substrate 40 away from the elastic layer 50. When the folding portion 15 drives the connecting portion 16 to fold relative to the planar portion 13, the third area 23 can be attached to the curved gasket 90, so that the curved gasket 90 can support the third area 23 and the connecting portion 16 to ensure the stability of the display module 100.

[0061] See also Figure 1 and Figure 5 In some embodiments, the projection of the second area 22 on the panel 10 covers the edge portions of the bending portion 14 and the flat portion 13, the projection of the first area 21 on the panel 10 covers the edge portions of the folding portion 15, and the projection of the third area 23 on the panel 10 covers the edge portions of the connecting portion 16 and the folding portion 15.

[0062] In this way, the area of ​​the second region 22 is larger than the area of ​​the bending portion 14, and the second region 22 also needs to cover the edge of the bending portion 14 and the flat portion 13. In this way, when the bending portion 14 is bent relative to the flat portion 13, the second region 22 can bear the stress generated during the bending. At the same time, the elastic modulus of the second region 22 of the transparent adhesive layer 20 is relatively small, that is, the second region 22 is relatively soft, and will not affect the bending of the panel 10 during the deformation process, thereby improving the bending of the display module 100.

[0063] Specifically, the third area 23 can completely cover the edge portions of the connecting portion 16 and the folding portion 15 to ensure that the edge portions of the connecting portion 16 and the bending portion 14 are supported; the first area 21 can correspond to the planar portion 13, and the first area 21 can support the planar portion 13; the second area 22 can correspond to the edge positions of the bending portion 14 and the planar portion 13, and the second area 22 is soft enough to meet the folding performance. At the same time, the second area 22 can undertake and absorb the stress concentration at the connection position of the planar portion 13 and the bending portion 14, so that the entire transparent adhesive layer 20 has good stability.

[0064] See also Figures 6 to 8 The preparation method of the embodiment of the present application is used to prepare the display module 100 of any of the above embodiments, and the preparation method includes:

[0065] S10, providing a panel 10;

[0066] S20, providing a screen 300 disposed on the second side 12 of the panel 10, the screen 300 having a plurality of through holes 301 arranged in an array;

[0067] S30, coating the colloid on the screen 300, and the colloid is coated on the second side 12 of the panel 10 through the through hole 301;

[0068] S40, separating the screen 300 from the panel 10, and providing a mask 400 to be pasted on the colloid, wherein the mask 400 includes a semi-masking area 401 and a transparent area 402;

[0069] S50 , curing the colloid, the colloid at the position corresponding to the semi-masking area 401 forms the second area 22 of the transparent adhesive layer 20 , and the colloid at the position corresponding to the transparent area 402 forms the first area 21 and the third area 23 of the transparent adhesive layer 20 .

[0070] In the display module 100, the electronic device 200 and the preparation method of the embodiment of the present application, the display module 100 includes a panel 10 and a transparent adhesive layer 20. The transparent adhesive layer 20 and the panel 10 are stacked to support the panel 10 and improve the strength of the display module 100. At the same time, the transparent adhesive layer 20 has a high light transmittance, which allows the light emitted by the functional component 30 to pass through the transparent adhesive layer 20 and the panel 10. At the same time, the light can also pass through the panel 10 and the transparent adhesive layer 20 after reflection to be received by the functional component 30. In addition, the preparation method of the embodiment of the present application has lower requirements for process accuracy, has a significant improvement effect on product yield, and is conducive to reducing product costs.

[0071] Specifically, a panel 10 is provided, and then a screen 300 can be set on the second side 12, and a plurality of through holes 301 are arranged in an array on the screen 300. Then, a colloid is coated on the screen 300, and the colloid can reach the second side 12 of the panel 10 through the through holes 301, so that the colloid can be evenly distributed on the second side 12. Then, the screen 300 is removed and a mask plate 400 is attached to the colloid, and the colloid is cured to form a transparent adhesive layer 20. The colloid at the corresponding position of the transmission area 402 forms the first area 21 and the third area 23 of the transparent adhesive layer 20, that is, the first area 21 and the third area 23 have a higher degree of curing, a larger elastic modulus, and better rigidity, which can be used to support the plane part 13 and the connecting part 16. The second area 22 is in a slightly cured state, and the second area 22 has a smaller elastic modulus than the first area 21, and the second area 22 is softer and can be bent. In the implementation manner of the present application, the colloid coating method is not limited, and the colloid coating can also be carried out by spraying with a linear nozzle, without the need for extensive modifications to existing equipment and the colloid flow rate can be better controlled to ensure the adjustability of product thickness.

[0072] See also Figure 7 In some embodiments, the screen 300 is formed with a window area 302 , the window area 302 shields the through hole 301 , and the window area 302 is arranged corresponding to the folding portion 15 of the panel 10 to prevent the colloid from being coated on the folding portion 15 .

[0073] Thus, the window area 302 can shield the through hole 301, preventing the colloid from being coated on the folding portion 15 through the through hole 301 to affect the folding movement of the folding portion 15. Thus, the folding portion 15 does not need to be provided with a transparent adhesive layer 20, so as to avoid the transparent adhesive layer 20 affecting the folding of the folding portion 15.

[0074] See also Figure 8 In some embodiments, the mask plate 400 further includes a masking area 403 , and the masking area 403 is used to mask the folded portion 15 of the panel 10 .

[0075] In this way, after the colloid is coated on the panel 10 through the screen 300, the screen 300 can be removed and the mask plate 400 can be attached to the side of the panel 10 with the colloid, and then the colloid is cured. The masking area 403 can shield the folding part 15 to prevent the folding part 15 of the panel 10 from being affected when the colloid is cured.

[0076] In addition, in the embodiments of the present application, the specific type of colloid is not limited, and it is only required that the colloid has good light transmittance after curing to meet different needs. In one example, the colloid can be ultraviolet curing glue (UV glue). At this time, the masking area 403 of the mask 400 can completely shield the ultraviolet light to prevent the ultraviolet light from affecting the panel 10; the transparent area 402 of the mask 400 can ensure the transmission of ultraviolet light and then cure the first area 21 and the third area 23; the semi-masked area 401 of the mask 400 can shield part of the ultraviolet light, thereby forming the second area 22 of the transparent glue layer 20. In another example, the colloid can be a thermal curing glue.
