[0026] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.
[0027] As mentioned in the background technology, in the related art, the display panel is divided into two parts after being bent. Generally, a support structure and a fixed adhesive are set between the two parts of the display panel to bond the two parts of the display panel to maintain the shape of the display panel. However, the inventors have found that the bending radius of the display panel in the related art is small, the distance between the two parts of the display panel is also small, and the bending stress of the display panel is large. Therefore, the thickness of the support structure and the fixed adhesive set between the two parts of the display panel is small, and the viscosity of the adhesive is low, which makes the two parts of the display panel easy to separate.
[0028] In view of this, the present application provides a display module and a display device to solve the problem that a bent display panel is easily separated.
[0029] Figure 1 FIG. 1 is a schematic diagram of the structure of a display module provided by an embodiment of the present application. Figure 1As shown, the display module includes: a display panel, including a first panel portion 101 and a second panel portion 102 arranged opposite to each other, and a bending portion 103 connected between the first panel portion 101 and the second panel portion 102, the first panel portion 101 includes at least one first conductive pad 1011, and the second panel portion 102 includes at least one second conductive pad 1021; a connecting structure, located between the first panel portion 101 and the second panel portion 102, the connecting structure includes a first conductive connecting structure 201 and a second conductive connecting structure 202, the first conductive connecting structure 201 is electrically connected to the first conductive pad 1011, the second conductive connecting structure 202 is electrically connected to the second conductive pad 1021, the first conductive pad 1011 and the second conductive pad 1021 are used to generate charges of opposite polarities, so that the first conductive connecting structure 201 and the second conductive connecting structure 202 have charges of opposite polarities and are magnetically attracted to each other.
[0030] Specifically, after the display panel is bent, there is a distance between the first panel portion 101 and the second panel portion 102 connected at both ends of the bending portion 103. A connection structure is provided between the first panel portion 101 and the second panel portion 102 to achieve close connection between the first panel portion 101 and the second panel portion 102. A first conductive pad 1011 is provided on the first panel portion 101 to be electrically connected to the first conductive connection structure 201. A second conductive pad 1021 is provided on the second panel portion 102 to be electrically connected to the second conductive connection structure 202. The first conductive connection structure 201 and the second conductive connection structure 202 are arranged opposite to each other, and charges with opposite polarities are respectively introduced into the first conductive connection structure 201 and the second conductive connection structure 202, so that an attraction is generated between the first conductive connection structure 201 and the second conductive connection structure 202, so that the first conductive connection structure 201 and the second conductive connection structure 202 are close to each other, driving the first panel portion 101 and the second panel portion 102 to be close to each other, thereby physically achieving close connection between the first panel portion 101 and the second panel portion 102, and reducing the risk of separation.
[0031] For example, a hole may be opened on the surface of the first panel portion 101 close to the second panel portion 102 to expose the copper conductive layer of the first panel portion 101 as the first conductive pad 1011. A hole may also be opened on the surface of the second panel portion 102 close to the first panel portion 101 to expose the copper conductive layer of the second panel portion 102 as the second conductive pad 1021. It should be noted that in order to prevent the copper exposed area of the display panel from abnormalities during environmental testing or electrical testing, a protective coating layer needs to be deposited in the copper exposed area other than the first conductive pad 1011 or the second conductive pad 1021 using vacuum sputtering technology to improve the reliability of the display module.
[0032] The technical solution provided in this embodiment realizes the close connection between the first panel portion 101 and the second panel portion 102 by setting a connection structure between the first panel portion 101 and the second panel portion 102. A first conductive connection structure 201 and a second conductive connection structure 202 are set in the connection structure, and are electrically connected to the first panel portion 101 and the second panel portion 102 respectively. By connecting the first conductive connection structure 201 and the second conductive connection structure 202 to charges of opposite polarities, an electromagnetic attraction is generated, so that the first panel portion 101 and the second panel portion 102 are closely connected and are not easily separated, thereby improving the overall structural stability of the display module.
[0033] Figure 2 FIG. 2 is a schematic diagram of the structure of a display module provided by another embodiment of the present application. Figure 2 As shown, the first conductive connection structure 201 includes at least one first conductive part 2011, and the first conductive part 2011 is electrically connected to the first conductive pad 1011; preferably, the first conductive connection structure 201 also includes a first conductive layer 2012, which is located on the side of the first conductive part 2011 away from the first panel part 101, and the first conductive layer 2012 is electrically connected to the first conductive part 2011; preferably, at least one first conductive part 2011 includes two first conductive parts 2011 spaced apart along a first direction F1 parallel to the first panel part 101, and the orthographic projection of the first conductive part 2011 on the first panel part 101 is located within the orthographic projection of the first conductive layer 2012 on the first panel part 101; preferably, the material of the first conductive layer 2012 includes metal; preferably, the material of the first conductive layer 2012 includes copper, and the first conductive layer 2012 is set as copper foil.
[0034] Specifically, at least one first conductive part 2011 is provided in the first conductive connection structure 201, which is directly electrically connected to the first conductive pad 1011, and an electromagnetic attraction force is generated between the first conductive part 2011 and the second conductive connection structure 202, so as to realize the connection between the first panel part 101 and the second panel part 102. By controlling the number of the first conductive parts 2011, the attraction force between the first conductive part 2011 and the second conductive connection structure can be adjusted, thereby adjusting the connection strength between the first panel part 101 and the second panel part 102.
[0035] The first conductive layer 2012 is arranged on the side of the first conductive part 2011 away from the first panel part 101, so that the first conductive layer 2012 is electrically connected to the first conductive part 2011, which is equivalent to increasing the effective surface area of the first conductive part 2011, thereby increasing the coupling capacitance between the first conductive connection structure 201 and the second conductive connection structure 202. In this way, the charge interaction force between the first conductive connection structure 201 and the second conductive connection structure 202 is enhanced, thereby further improving the structural stability of the display module.
[0036] Preferably, in some embodiments, see Figure 2 The first conductive connection structure 201 includes two first conductive portions 2011 spaced apart along a first direction F1 parallel to the first panel portion 101, and the orthographic projection of the first conductive portion 2011 on the first panel portion 101 is located within the orthographic projection of the first conductive layer 2012 on the first panel portion 101. Therefore, the provision of the first conductive layer 2012 is conducive to forming a more uniform electric field distribution on the surface of the first conductive connection structure 201, and further conducive to maintaining the stability and reliability of the display panel in a bent state.
[0037] The material of the first conductive layer 2012 is preferably metal, preferably copper. Metal conductive layers, especially copper, are widely used due to their excellent electrical conductivity and processability. Metal conductive layers usually have high mechanical strength, which can enhance the overall strength of the connection structure and make it more wear-resistant and impact-resistant. The metal conductive layer also has good thermal conductivity, which helps to dissipate heat and prevent performance degradation or damage caused by overheating. Exemplarily, the first conductive layer 2012 can be set to copper foil, which is easy to process by etching technology and has good strength and ductility.
[0038] In this embodiment, by providing a first conductive part 2011 and a first conductive layer 2012 in the first conductive connection structure 201, and preferably using metal (such as copper) as the material, it is further beneficial to enhance the stability and mechanical strength of the connection structure, while providing protection and facilitating heat dissipation, thereby further improving the overall performance and reliability of the display module.
[0039] In one embodiment, the material of the first conductive part 2011 includes metal or conductive particles; preferably, the material of the first conductive part 2011 includes copper, and the first conductive part 2011 is configured as copper foil; preferably, the material of the first conductive part 2011 and the first conductive layer 2012 is the same.
[0040] Specifically, using metal as the material of the first conductive part 2011 can ensure that the first conductive part 2011 has a very high electrical conductivity, and the metal is generally chemically stable, not easy to oxidize or corrode, and is conducive to maintaining the stability of the first conductive part 2011 in long-term use. In addition, metal generally has high mechanical strength and toughness, so that the first conductive part 2011 can withstand certain mechanical stresses, such as bending, folding or vibration, and is not easy to be damaged. Further, the metal can be processed by a variety of processes, such as stamping, etching, laser cutting, etc., which is convenient for forming complex shapes and structures to meet different design requirements. Metal is also a good thermal conductor, which helps the first conductive part 2011 to dissipate heat and prevents the heat generated by the long-term operation of the display panel from accumulating and causing the temperature to rise. Copper is a commonly used conductive metal, which is widely used because of its high conductivity, good ductility and strong corrosion resistance. Copper is preferably used as the material of the first conductive part 2011, which can provide excellent electrical conductivity and stability, while ensuring mechanical strength and processing convenience. The first conductive part 2011 and the first conductive layer 2012 may be made of the same material, such as copper foil, to ensure that the electrical properties of the first conductive part 2011 and the first conductive layer 2012 are consistent.
[0041] Conductive particles refer to tiny particles with conductivity, which can be used to make conductive glue, conductive coatings, conductive plastics, etc. The conductive particles can be evenly dispersed in the base material to form a flexible first conductive part 2011, which is suitable for display panels that need to be bent or deformed. In addition, the first conductive part 2011 made of conductive particles is thinner and lighter.
[0042] For example, a conductive particle composite adhesive is prepared using conductive particles, and is attached between the first conductive pad 1011 and the first conductive layer 2012 to serve as the first conductive portion 2011. For example, the conductive particles may be metal powder (such as silver, copper, nickel, etc.), carbon-based materials (such as graphite, carbon nanotubes, graphene), metal fibers, or metallized plastic particles, etc. The shape of the conductive particles may be spherical, flaky, fibrous, etc., and this application does not limit this.
[0043] In this embodiment, by setting the material of the first conductive part 2011 to include metal or conductive particles, the structural stability of the display module is further improved.
[0044] Figure 3 FIG. 2 is a schematic diagram of the structure of a display module provided by another embodiment of the present application. Figure 3 As shown, the second conductive connection structure 202 includes at least one second conductive part 2021, which is electrically connected to the second conductive pad 1021; the material of the second conductive part 2021 includes metal or conductive particles; preferably, the material of the second conductive part 2021 includes copper, and the second conductive part 2021 is set as copper foil.
[0045] Specifically, at least one second conductive part 2021 is provided in the second conductive connection structure 202, which is directly electrically connected to the second conductive pad 1021. An electromagnetic attraction force is generated between the second conductive part 2021 and the first conductive connection structure 201, thereby realizing the connection between the first panel part 101 and the second panel part 102. By controlling the number of the second conductive parts 2021, the attraction force between the second conductive parts 2021 and the first conductive connection structure 201 can be adjusted, thereby adjusting the connection strength between the first panel part 101 and the second panel part 102.
[0046] Using metal as the material of the second conductive part 2021 can ensure that the second conductive part 2021 has a very high electrical conductivity, and the metal is generally chemically stable, not easy to oxidize or corrode, which is conducive to maintaining the stability of the second conductive part 2021 in long-term use. In addition, metals generally have high mechanical strength and toughness, so that the second conductive part 2021 can withstand certain mechanical stresses, such as bending, folding or vibration, and is not easy to damage. Further, the metal can be processed by a variety of processes, such as stamping, etching, laser cutting, etc., which is convenient for forming complex shapes and structures to meet different design requirements. Metal is also a good thermal conductor, which helps the second conductive part 2021 to dissipate heat and prevent the heat generated by the long-term operation of the display panel from accumulating and causing the temperature to rise. Copper is a commonly used conductive metal, which is widely used because of its high conductivity, good ductility and strong corrosion resistance. Copper is preferably used as the material of the second conductive part 2021, which can provide excellent electrical conductivity and stability, while ensuring mechanical strength and processing convenience.
[0047] Conductive particles refer to tiny particles with conductivity, which can be used to make conductive glue, conductive coatings, conductive plastics, etc. The conductive particles can be evenly dispersed in the base material to form a flexible second conductive part 2021, which is suitable for display panels that need to be bent or deformed. In addition, the second conductive part 2021 made of conductive particles is lighter and thinner.
[0048] Exemplarily, a conductive particle composite adhesive is prepared using conductive particles, and the conductive particles are applied to the surface of the second conductive pad 1021 away from the second panel portion 102 to form the second conductive portion 2021. Exemplarily, the conductive particles can be metal powder (such as silver, copper, nickel, etc.), carbon-based materials (such as graphite, carbon nanotubes, graphene), metal fibers or metallized plastic particles, etc. The shape of the conductive particles can be spherical, flaky, fibrous, etc., and this application does not limit this.
[0049] In this embodiment, by disposing the second conductive part 2021 in the second conductive connection structure 202 and preferably using metal or conductive particles as the material of the second conductive part 2021 , the structural stability of the display module is further improved.
[0050] It should be noted that the present application does not specifically limit the number and position of the first conductive part 2011 and the second conductive part 2021 in the above embodiments. The positions of the first conductive part 2011 and the second conductive part 2021 are arranged according to the copper exposed area of the display panel to form a special-shaped conductive connection structure.
[0051] Figure 4 FIG. 2 is a schematic diagram of the structure of a display module provided by another embodiment of the present application. Figure 4 As shown, the second conductive connection structure 202 also includes a second conductive layer 2022, which is located on the side of the second conductive part 2021 away from the second panel part 102, and the second conductive layer 2022 is electrically connected to the second conductive part 2021; preferably, at least one second conductive part 2021 includes two second conductive parts 2021 spaced apart along the first direction F1, and the orthographic projection of the second conductive part 2021 on the first panel part 101 is located within the orthographic projection of the second conductive layer 2022 on the first panel part 101; preferably, the material of the second conductive layer 2022 includes metal; preferably, the material of the second conductive layer 2022 includes copper, and the second conductive layer 2022 is set to copper foil; preferably, the material of the second conductive layer 2022 and the second conductive part 2021 is the same.
[0052] Specifically, a second conductive layer 2022 is disposed on a side of the second conductive portion 2021 away from the second panel portion 102, so that the second conductive layer 2022 is electrically connected to the second conductive portion 2021, which is equivalent to increasing the effective surface area of the second conductive portion 2021, thereby increasing the coupling capacitance between the first conductive connection structure 201 and the second conductive connection structure 202. This configuration enhances the charge interaction force between the first conductive connection structure 201 and the second conductive connection structure 202, thereby further improving the structural stability of the display module.
[0053] Preferably, in some embodiments, see Figure 4 The second conductive connection structure 202 includes two second conductive portions 2021 spaced apart along the first direction F1, and the orthographic projection of the second conductive portion 2021 on the first panel portion 101 is located within the orthographic projection of the second conductive layer 2022 on the first panel portion 101. Providing the second conductive layer 2022 is conducive to forming a more uniform electric field distribution on the surface of the second conductive connection structure 202, and is further conducive to maintaining the stability and reliability of the display panel in a bent state.
[0054] The material of the second conductive layer 2022 is preferably metal, and preferably, copper can be selected. Metal conductive layers, especially copper, are widely used due to their excellent electrical conductivity and processability. Metal conductive layers usually have high mechanical strength, which can enhance the overall strength of the connection structure, making it more wear-resistant and impact-resistant. The metal conductive layer also has good thermal conductivity, which helps to dissipate heat and prevent performance degradation or damage due to overheating. The second conductive part 2021 and the second conductive layer 2022 can be set to the same material, for example, both are copper foil, to ensure that the electrical properties between the second conductive part 2021 and the second conductive layer 2022 are consistent.
[0055] In this embodiment, by setting a second conductive layer 2022 in the connection structure and preferably using metal (such as copper) as the material, it is further beneficial to enhance the stability and mechanical strength of the connection structure, while providing protection and facilitating heat dissipation, thereby further improving the overall performance and reliability of the display module.
[0056] Figure 5 FIG. 2 is a schematic diagram of the structure of a display module provided by another embodiment of the present application. Figure 5 The display module also includes a buffer layer 104, which is located between the first conductive layer 2012 and the second conductive part 2021, and the orthographic projection of the first conductive layer 2012 on the first panel part 101 is located within the orthographic projection of the buffer layer 104 on the first panel part 101; preferably, the material of the buffer layer 104 includes foam; preferably, both sides of the buffer layer 104 are coated with double-sided tape.
[0057] Specifically, a buffer layer 104 is provided between the first conductive layer 2012 and the second conductive part 2021, and the orthographic projection of the buffer layer 104 on the first panel part 101 covers the orthographic projection of the first conductive layer 2012 on the first panel part 101, so as to avoid a short circuit between the first conductive connection structure 201 and the second conductive connection structure 202. Double-sided adhesive is coated on both sides of the buffer layer 104 to make the buffer layer 104 sticky, so that the surfaces of the buffer layer 104 that are in contact with the first conductive layer 2012 and the second conductive part 2021 can be bonded. It should be noted that Figure 5 The structure shown is only an example provided by this embodiment and does not limit the present application. In other embodiments, the buffer layer 104 may also be in contact with other components of the display module. In this way, the buffer layer 104 can evenly disperse the pressure applied to the first conductive layer 2012 and the second conductive part 2021, reduce local stress concentration, prevent damage to the connection structure due to uneven pressure, and help protect the first conductive layer 2012 and the second conductive part 2021 from mechanical damage, such as bending, impact or wear, thereby maintaining the integrity and functionality of the first conductive layer 2012 and the second conductive part 2021.
[0058] The material of the buffer layer 104 is preferably foam. Foam is a lightweight material with good elasticity and compressibility, and is commonly used for buffering and shock absorption. By using foam and double-sided tape, the buffer layer 104 can maintain its buffering and bonding effects for a long time, and is not easy to fall off or degrade, thereby improving the durability of the display module. In addition, the foam material can be cut into different shapes and thicknesses as needed to adapt to different design requirements and space constraints, thereby improving the flexibility of design.

[0068] Specifically, a first support portion 106 is provided between the first panel portion 101 and the first conductive layer 2012 to support the first panel portion 101. A second support portion 107 is provided between the second panel portion 102 and the buffer layer 104 to support the second panel portion 102. When the flexible display panel is bent, the circuits and other sensitive components inside it may be affected by stress. The provision of the first support portion 106 and the second support portion 107 can play a certain buffering role and reduce the mechanical stress on these components. In addition, the provision of the first support portion 106 and the second support portion 107 is conducive to maintaining the predetermined shape of the display panel, especially in products designed for a specific curved shape, the first support portion 106 and the second support portion 107 can ensure that the panel maintains a consistent shape during manufacturing and use.

[0070] The material of the first support portion 106 and the second support portion 107 is preferably polyimide.
