Description

Technical Field

[0001] This application relates to the field of display technology, and in particular to a display module and display device. Background Technology

[0002] With the development of display technology, the demand for and application range of display devices are constantly expanding. Commonly used display devices include mobile phones, televisions, tablets, laptops, and monitors.

[0003] Display devices typically include display modules, but existing display modules are quite thick. Utility Model Content

[0004] This application provides a display module and display device. It solves the problem of the excessive thickness of existing OLED display modules. The technical solution is as follows:

[0005] On the one hand, a display module is provided, including: a display panel, a carbon fiber support layer, a buffer layer and a metal support layer;

[0006] The carbon fiber support layer is connected to the back of the display panel;

[0007] The buffer layer is connected to the side of the carbon fiber support layer opposite to the display panel;

[0008] The metal support layer is connected to the side of the buffer layer opposite to the display panel;

[0009] The carbon fiber support layer is a layered structure made of carbon fiber material.

[0010] Due to its high rigidity and resistance to deformation, carbon fiber support layer effectively resists impacts to the back of the display module, thus protecting the display panel. Furthermore, the buffer layer and carbon fiber support layer work together to further reduce damage to the display panel, leveraging the buffer's cushioning and the support's impact resistance. Moreover, the carbon fiber support layer maintains good impact resistance despite its relatively small thickness, allowing for a reduction in the overall thickness of the display module while simultaneously enhancing its impact resistance.

[0011] In some possible implementations, the thickness of the carbon fiber support layer is less than the thickness of the buffer layer.

[0012] Due to the high rigidity and resistance to deformation of carbon fiber materials, even with a relatively thin carbon fiber support layer, it still exhibits good impact resistance. Furthermore, the thickness of the buffer layer affects its cushioning effect; a thicker buffer layer provides better cushioning.

[0013] In some possible implementations, the thickness of the carbon fiber support layer is greater than or equal to 0.007 mm, and the thickness of the buffer layer is greater than or equal to 0.05 mm.

[0014] In some possible implementations, the display module further includes an adhesive layer located between the carbon fiber support layer and the display panel, wherein the carbon fiber support layer is connected to the back of the display panel via the adhesive layer.

[0015] In some possible implementations, the adhesive layer is greater than or equal to 0.023 mm.

[0016] In some possible implementations, the sum of the thicknesses of the adhesive layer, the carbon fiber support layer, and the buffer layer ranges from 0.08 mm to 0.12 mm.

[0017] Even with a relatively small thickness, the carbon fiber support layer still exhibits good impact resistance. The carbon fiber support layer can effectively reduce the thickness of the display module.

[0018] In some possible implementations, the display module further includes: an auxiliary support layer located between the display panel and the adhesive layer, wherein the side of the auxiliary support layer facing away from the adhesive layer is bonded to the display panel;

[0019] The adhesive layer is bonded to the auxiliary support layer on the side facing the display panel, and the adhesive layer is bonded to the carbon fiber support layer on the side facing away from the display panel.

[0020] The auxiliary support layer can be used to support the display panel, and because the carbon fiber support layer is very rigid, the auxiliary support layer can effectively prevent the carbon fiber support layer from damaging the back of the display panel.

[0021] In some possible implementations, the side of the buffer layer facing the display panel is bonded to the side of the carbon fiber support layer facing away from the display panel, and the side of the buffer layer facing away from the display panel is bonded to the side of the metal support layer facing the display panel.

[0022] In some possible implementations, the density of the buffer layer ranges from 0.67 g / cm³ to 0.87 g / cm³.

[0023] The density of the buffer layer in the display module affects the buffering effect of the buffer layer; a higher density buffer layer has a better buffering effect.

[0024] On the other hand, a display device is provided, comprising: a housing, and a display module connected to the housing, wherein the display module is the display module according to any of the preceding claims. Attached Figure Description

[0025] To more clearly illustrate the technical solutions in some embodiments, the accompanying drawings used in the description of the embodiments will be briefly introduced below. Obviously, the accompanying drawings described below are only some embodiments of this application. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0027] Figure 2 yes Figure 1 The diagram shows the film structure of the display module at point A-A'.

[0028] Figure 3 This is a schematic diagram of the film layer structure of a display module provided in an embodiment of this application;

[0029] Figure 4 yes Figure 1 The diagram shows the film structure of the display module at point B-B'. Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0031] Please refer to Figure 1 and Figure 2 , Figure 1 This is a top view of a display module provided in an embodiment of this application. Figure 2 yes Figure 1 The diagram shows the film structure of the display module at point A-A'. The display module 000 may include: a display panel 100, a carbon fiber support layer 200, a buffer layer 300, and a metal support layer 400.

[0032] The carbon fiber support layer 200 in the display module 000 is connected to the back of the display panel 100 to support the display panel 100.

[0033] The buffer layer 300 in the display module 000 is connected to the side of the carbon fiber support layer 200 away from the display panel 100. The buffer layer 300 has good buffering performance, and in the event of an impact to the back of the display module 000, the buffer layer 300 can effectively reduce the damage to the display panel 100.

[0034] The metal support layer 400 in the display module 000 is connected to the side of the buffer layer 300 opposite to the display panel 100. The metal support layer 400 supports the display panel 100. Here, the metal support layer 400 also has good conductivity; therefore, static electricity in the display module 000 can be released through the metal support layer 400, effectively preventing the accumulation of static electricity in the display module 000 in the display panel 100, resulting in better display performance of the display panel 100. For example, the metal support layer 400 in the display module 000 can be made of copper.

[0035] The carbon fiber support layer 200 in the display module 000 is a layered structure made of carbon fiber material. Carbon fiber material has high hardness and is not easily deformed. Therefore, after the back of the display module 000 is impacted, the carbon fiber support layer 200 can effectively resist the impact force, thus effectively protecting the display panel 100. Furthermore, the buffer layer 300 works in conjunction with the carbon fiber support layer 200, further reducing damage to the display panel 100 due to the buffering effect of the buffer layer 300 and the impact resistance of the carbon fiber support layer 200. For example, the Rockwell hardness of the carbon fiber support layer 200 can be 60 HRC.

[0036] Furthermore, even with a relatively small thickness, the carbon fiber support layer 200 still exhibits excellent impact resistance. Therefore, while improving the impact resistance of the display module 000, the thickness of the display module 000 can be effectively reduced.

[0037] In summary, the display module provided in this application uses a carbon fiber support layer, which is a layered structure made of carbon fiber material. Carbon fiber material is characterized by high hardness and resistance to deformation. Therefore, when the back of the display module is impacted, the carbon fiber support layer can effectively resist the impact force, thus effectively protecting the display panel. Furthermore, the buffer layer and the carbon fiber support layer work together to further reduce damage to the display panel, thanks to the buffering effect of the buffer layer and the impact resistance of the carbon fiber support layer. Moreover, even with a relatively small thickness, the carbon fiber support layer still exhibits good impact resistance. Therefore, while improving the impact resistance of the display module, the thickness of the display module can be effectively reduced.

[0038] In some embodiments, please refer to Figure 3 , Figure 3This is a schematic diagram of the film layer structure of a display module provided in an embodiment of this application. The display module 000 may further include a polarizer 500 located on the side of the display panel 100 opposite to the carbon fiber support plate 200. That is, the polarizer 500 is located on the display side of the display panel 100, and this display side is the side of the display panel 100 used for displaying the image. The polarizer 500 can be bonded to the display side of the display panel 100. The polarizer 500 can effectively reduce the reflectivity of the display panel 100 to ambient light, so as to ensure that the image displayed in the display area within the display panel 100 has a better effect.

[0039] In some embodiments, such as Figure 3 As shown, the display module 000 may further include: a protective cover plate 600 located on the side of the polarizer 500 away from the display panel 100, and an optical adhesive layer 700 located between the polarizer 500 and the protective cover plate 600.

[0040] The protective cover 600 is used to protect the display side of the display panel 100. Here, the optical adhesive layer 700 is bonded to both sides of the polarizer 500 and the protective cover 600, respectively, to achieve adhesion between the protective cover 600 and the polarizer 500. The optical adhesive layer 700 is typically made of transparent adhesive (e.g., acrylic adhesive). This ensures that light emitted from the display panel 100 passes through the optical adhesive layer 700 and the protective cover 600 before exiting. Furthermore, the optical adhesive layer 700 has good cushioning properties, thus effectively reducing the probability of the protective cover 600 breaking when the front of the display module 000 is subjected to impact.

[0041] It should be noted that the display module 000 may further include a light-shielding ink layer 800. The light-shielding ink layer 800 is located on the side of the protective cover 600 facing the display panel 100, and covers the edge portion of the protective cover 600. The light-shielding ink layer 800 can be used to form the bezel of the display module 000, shielding the driving circuits and connecting traces within the display module 000, thereby achieving an aesthetic purpose.

[0042] In some embodiments, due to the high hardness and resistance to deformation of carbon fiber material, the carbon fiber support layer 200 still exhibits good impact resistance even with a relatively small thickness. Furthermore, the thickness of the buffer layer 300 affects its cushioning effect; a thicker buffer layer 300 provides better cushioning. Therefore, in the display module 000, the thickness of the carbon fiber support layer 200 is less than the thickness of the buffer layer 300. For example, the thickness of the carbon fiber support layer 200 is greater than or equal to 0.007 mm, and the thickness of the buffer layer 300 is greater than or equal to 0.05 mm.

[0043] Furthermore, the density of the buffer layer 300 in the display module 000 affects the buffering effect of the buffer layer 300; a higher density buffer layer 300 provides better buffering. For example, the density of the buffer layer 300 can range from 0.67 g / cm³ to 0.87 g / cm³.

[0044] It should be noted that the buffer layer 300 in the display module 000 has adhesive properties. In this way, the side of the buffer layer 300 facing the display panel 100 can be bonded to the side of the carbon fiber support layer 200 away from the display panel 100, and the side of the buffer layer 300 away from the display panel 100 can be bonded to the side of the metal support layer 200 facing the display panel 100.

[0045] For example, the buffer layer 300 in the display module 000 can be made of high-density foam with adhesive sides, which can be bonded to the carbon fiber support layer 200 and the metal support layer 200 on both sides respectively.

[0046] In some embodiments, such as Figure 3 As shown, the display module 000 may further include an adhesive layer 900. The adhesive layer 900 is located between the carbon fiber support layer 200 and the display panel 100. The carbon fiber support layer 200 is connected to the back of the display panel 100 via the adhesive layer 900, thereby enabling the carbon fiber support layer 200 to effectively support the display panel 100. For example, the adhesive layer 900 in the display module 000 may be made of pressure-sensitive adhesive.

[0047] It should be noted that, in order to ensure good adhesion of the adhesive layer 900 and to maintain a small thickness, the thickness of the adhesive layer 900 in the display module 000 can be greater than the thickness of the carbon fiber support layer 200, and the thickness of the adhesive layer 900 can be less than the thickness of the buffer layer 300. For example, the thickness of the adhesive layer 900 can be greater than or equal to 0.023 mm.

[0048] It should also be noted that, in order to ensure that the thickness of the display module 000 is small, the sum of the thicknesses of the adhesive layer 900, the carbon fiber support layer 200 and the buffer layer 300 in the display module 000 ranges from 0.08 mm to 0.12 mm.

[0049] Furthermore, while reducing the thickness of the display module 000, after conducting a drop ball test on the back of the display module 000, the display panel 100 is protected by the carbon fiber support layer 200 and the buffer layer 300. The deformation of the touch layer, encapsulation layer, light-emitting layer and driving backplate in the display panel 100 is relatively small, the display module 000 has good impact resistance, and the display panel 100 has a better display effect.

[0050] For example, when the thickness of the adhesive layer 900, the carbon fiber support layer 200 and the buffer layer 300 in the display module 000 is 0.1 mm, after a drop ball test on the back of the display module 000, the longitudinal strain of the touch layer in the display panel 100 is 0.617%, the longitudinal strain of the encapsulation layer in the display panel 100 is 0.597%, and the longitudinal strain of the light-emitting layer and the driving backplate in the display panel 100 is 0.551%.

[0051] In some embodiments, such as Figure 3 As shown, the display module 000 may further include an auxiliary support layer 1000, which is located between the display panel 100 and the adhesive layer 900, and the side of the auxiliary support layer 1000 facing away from the adhesive layer 900 is bonded to the display panel.

[0052] The auxiliary support layer 1000 can be used to support the display panel 100, and because the carbon fiber support layer 200 has high rigidity, the auxiliary support layer 1000 can effectively prevent the carbon fiber support layer 200 from damaging the back of the display panel 100.

[0053] The adhesive layer 900 is bonded to the auxiliary support layer 1000 on the side facing the display panel 100, and to the carbon fiber support layer 200 on the side facing away from the display panel 100. In this way, the carbon fiber support layer 200 is connected to the back of the display panel 100 through the adhesive layer 900 and the auxiliary support layer 1000.

[0054] In some embodiments, please refer to Figure 4 , Figure 4 yes Figure 1 The diagram shows the film layer structure of the display module at point B-B'. The display panel 100 in the display module 000 may include: a first panel portion 110 and a second panel portion 120 disposed opposite to each other, and a panel bending portion 130 for connecting the first panel portion 110 and the second panel portion 120. That is, the panel bending portion 130 may be located between the first panel portion 110 and the second panel portion 120, and one side of the panel bending portion 130 may be connected to the first panel portion 110, and the other side of the panel bending portion 130 may be connected to the second panel portion 120. The side of the first panel portion 110 facing away from the second panel portion 120 has a display surface for displaying an image.

[0055] It should be noted that the auxiliary support layer 1000, adhesive layer 900, carbon fiber support layer 200, buffer layer 300 and metal support layer 400 in the display module 000 are located between the first panel portion 110 and the second panel portion 120. The auxiliary support layer 1000, carbon fiber support layer 200 and metal support layer 400 can support the first panel portion 110.

[0056] It should also be noted that the display module 000 may further include: a support column 1100 located between the metal support layer 400 and the second panel portion 120, and a second panel support layer 1200. The second panel support layer 1200 is closer to the second panel portion 120 than the support column 1100. The second panel support layer 1200 can be used to support the second panel portion 120; the support column 1100 can be used to bond the metal support layer 400 and the second panel support layer 1200, and to support both the metal support layer 400 and the second panel support layer 1200.

[0057] In this application, the display module 000 may include a protective colloid 1300. The protective colloid 1300 covers the side of the panel bend 130 that faces away from the first panel portion 110. In this way, when the side of the display device on which the display module 000 is mounted is impacted, the protective colloid 1300 can protect the side of the panel bend 130 that faces away from the first panel portion 110.

[0058] In summary, the display module provided in this application uses a carbon fiber support layer, which is a layered structure made of carbon fiber material. Carbon fiber material is characterized by high hardness and resistance to deformation. Therefore, when the back of the display module is impacted, the carbon fiber support layer can effectively resist the impact force, thus effectively protecting the display panel. Furthermore, the buffer layer and the carbon fiber support layer work together to further reduce damage to the display panel, thanks to the buffering effect of the buffer layer and the impact resistance of the carbon fiber support layer. Moreover, even with a relatively small thickness, the carbon fiber support layer still exhibits good impact resistance. Therefore, while improving the impact resistance of the display module, the thickness of the display module can be effectively reduced.

[0059] This application embodiment also provides a display device, which may include: a housing, and a display module connected to the housing, wherein the display module is...
