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] With the development of display technology, display devices (such as mobile phones, laptops or tablets, etc.) are increasingly used in people's lives. Among them, organic light-emitting diode (OLED) display devices have the advantages of active light emission, wide viewing angle, high contrast, fast response speed, low power consumption, and ultra-lightness, and therefore have attracted widespread attention.

[0054] Some embodiments of the present disclosure provide a display device 1000, such as Figure 1 As shown, the display device 1000 may be any device that displays content, whether in motion (eg, video) or stationary (eg, still image), and whether textual or graphic.

[0055] Exemplarily, the display device 1000 can be a television, a laptop computer, a tablet computer, a mobile phone, a personal digital assistant (PDA), a navigator, a wearable device, an augmented reality (AR) device, a virtual reality (VR) device, a medical display, a car display, an aircraft display, a spliced ​​screen, or any other product or component with a display function.

[0056] In some embodiments, as Figures 2A to 2D As shown, the display device 1000 includes a display module 100 and a fixing plate. The display module 100 is located on one side of the fixing plate and is connected to the fixing plate. In the case where the display device 1000 is a mobile phone, the fixing plate can be a bottom plate in the housing. In the case where the display device 1000 is a car display, the fixing plate can be a plate-shaped portion in the vehicle frame. In the case where the display device 1000 is a spliced ​​screen, the fixing plate can be a plate-shaped portion in the fixing frame.

[0057] like Figures 3 to 5B As shown, the display module 100 includes a display panel 10 , a cover plate 20 , a support layer 30 and a printed circuit board 40 .

[0058] Exemplarily, the above-mentioned display panel 10 can be: an organic light-emitting diode (OLED) display panel 10, a quantum dot light-emitting diode (QLED) display panel 10, an active matrix organic light-emitting diode (AMOLED) display panel 10, etc., and the embodiments of the present disclosure are not specifically limited here.

[0059] like Figures 3 to 5B As shown, the display panel 10 includes a main body portion 11 and a binding portion 12 connected to each other. The main body portion 11 is configured to display images. The main body portion 11 has a display area A and a peripheral area B provided on at least one side of the display area A. The display area A is the area where images are displayed and is configured to accommodate multiple pixel units. The peripheral area B is an area where images are not displayed and is configured to accommodate display driver circuits, such as gate driver circuits and source driver circuits.

[0060] like Figures 3 to 5B As shown, the main body 11 has a display side 11A and a non-display side 11B that are arranged opposite to each other. The display side 11A refers to the side of the main body 11 that displays an image ( Figure 3 The non-display side 11B refers to the other side opposite to the display side 11A ( Figure 3 on the upper side of the ).

[0061] like Figures 3 to 5B As shown, the cover plate 20 is located on the display side 11A of the main body 11 and is connected to the main body 11. At least a portion of the cover plate 20 extends beyond the display panel 10. In this way, the cover plate 20 can reduce the risk of the display panel 10 being scratched.

[0062] In some examples, the material of cover plate 20 includes at least one of ceramic, glass, polycarbonate, polyimide, polyethylene terephthalate, and polystyrene.

[0063] like Figures 3 to 5B As shown, the support layer 30 is located on the non-display side 11B of the main body 11 and is connected to the support layer 30. In this way, the support layer 30 can support the display panel 10 and reduce the risk of deformation of the display panel 10 due to external forces.

[0064] In some examples, the material of the support layer 30 includes at least one of polyimide, polyethylene terephthalate, stainless steel, aluminum alloy, aluminum, carbon fiber, and ceramic.

[0065] like Figures 3 to 5BAs shown, the printed circuit board 40 is located on a side of the support layer 30 away from the main body 11 and is connected to the main body 11 . In this way, the printed circuit board 40 can provide signals to the main body 11 to drive the main body 11 to display images.

[0066] In some examples, such as Figures 3 to 5B As shown, through the bending process, the binding portion 12 can be bent along a bending axis extending in the first direction X toward the side of the main body 11 of the display panel 10 close to the support layer 30. The portion of the binding portion 12 that is bent toward the support layer 30 away from the main body 11 is connected to the printed circuit board 40, thereby reducing the bezel of the display module 100. The bending axis is not an actual structure in the display panel 10; it is merely a concept proposed to illustrate the bending process of the display panel 10.

[0067] like Figures 3 to 5B As shown, the display module 100 further includes a flexible circuit board 50 and a driver chip 60. The flexible circuit board 50 is located on a side of the printed circuit board 40 and the binding portion 12 away from the cover plate 20. The flexible circuit board 50 connects the printed circuit board 40 and the binding portion 12. The driver chip 60 is located on the flexible circuit board 50 or on the binding portion 12.

[0068] In related art, when a display device is subjected to an impact, the display panel is easily damaged. The inventors have discovered that the fixing plate is rigidly connected to the display panel. For example, the fixing plate is connected to the display panel via clips, threads, or middle frame adhesive. When the display device is subjected to an impact, most or all of the impact force is applied to the display panel, resulting in a greater impact force on the display panel and making it more susceptible to damage.

[0069] In order to solve the above technical problems, Figures 2A to 5B As shown, the display module 100 provided in some embodiments of the present disclosure further includes a first elastic fixing member 70 and / or a second elastic fixing member 80 .

[0070] In some embodiments, as Figure 2A and Figure 3 As shown, the display module 100 includes a first elastic fixing member 70. The first elastic fixing member 70 is located on the side of the support layer 30 away from the main body 11. One end of the first elastic fixing member 70 is connected to the support layer 30, and the other end is used to connect to the fixing plate. If the display panel 10 is impacted, the display panel 10 can move toward the fixing plate, driving the end of the first elastic fixing member 70 connected to the support layer 30 toward the fixing plate, causing the first elastic fixing member 70 to undergo compressive elastic deformation.

[0071] Arranged in this manner, the first elastic fixing member 70 can connect the fixing plate and the support layer 30, thereby connecting the fixing plate and the display module 100. When the display device 1000 is impacted, the display panel 10 moves toward the fixing plate, causing the end of the first elastic fixing member 70 connected to the support layer 30 to move toward the fixing plate. The first elastic fixing member 70 undergoes compressive elastic deformation, absorbing some of the impact force, thereby reducing the impact force acting on the display panel 10 and reducing the risk of damage to the display panel 10. After the impact force disappears, the first elastic fixing member 70 drives the display panel 10 to move away from the fixing plate, returning the display panel 10 to its original position.

[0072] In other embodiments, Figure 2B and Figure 4 As shown, the display module 100 includes a second elastic fixing member 80. The second elastic fixing member 80 is located on the side of the cover plate 20 away from the main body 11. One end of the second elastic fixing member 80 is connected to the cover plate 20, and the other end is used to connect to the fixing plate. If the display panel 10 is impacted, the display panel 10 can move toward the fixing plate, driving the end of the second elastic fixing member 80 connected to the cover plate 20 to move toward the fixing plate, causing the second elastic fixing member 80 to produce compressive elastic deformation.

[0073] Arranged in this manner, the second elastic fixing member 80 can connect the fixing plate and the cover plate 20, thereby connecting the fixing plate and the display module 100. When the display device 1000 is impacted, the display panel 10 moves toward the fixing plate, causing the end of the second elastic fixing member 80 connected to the cover plate 20 to move toward the fixing plate. The second elastic fixing member 80 undergoes compressive elastic deformation, absorbing some of the impact force, thereby reducing the impact force acting on the display panel 10 and reducing the risk of damage to the display panel 10. After the impact force disappears, the second elastic fixing member 80 drives the display panel 10 to move away from the fixing plate, returning the display panel 10 to its original position.

[0074] In some other embodiments, Figure 2C 、 Figure 2D and Figures 5A to 6BAs shown, the display module 100 includes a first elastic fixing member 70 and a second elastic fixing member 80. The first elastic fixing member 70 is located on the side of the support layer 30 away from the main body 11. One end of the first elastic fixing member 70 is connected to the support layer 30, and the other end is used to connect to the fixing plate. The second elastic fixing member 80 is located on the side of the cover plate 20 away from the main body 11. One end of the second elastic fixing member 80 is connected to the cover plate 20, and the other end is used to connect to the fixing plate. This large number of elastic fixing members can enhance the connection force between the display module 100 and the fixing plate, which is conducive to improving the connection stability of the display module 100.

[0075] In some embodiments, as Figure 7A and Figure 7B As shown, the elastic fixing member (first elastic fixing member 70 and / or second elastic fixing member 80) includes a vacuum suction cup 1. The fixing end of the vacuum suction cup 1 is connected to the fixing plate and one of the support layer 30 or the cover plate 20, and the suction end is suction-connected to the other of the fixing plate and the support layer 30 or the cover plate 20. This facilitates connection and removal of the display module 100 and the fixing plate.

[0076] In some examples, the vacuum suction cup 1 includes a fixed portion 101, an elastic portion 102, and a barrier structure. The elastic portion 102 is located on one side of the fixed portion 101, and the fixed portion 101 and the elastic portion 102 enclose an adsorption chamber having an opening, and the opening is arranged opposite to the fixed portion 101. The elastic portion 102 has a vent 1021, which connects the adsorption chamber and the atmosphere. The end of the fixed portion 101 away from the elastic portion 102 forms a fixed end, and the end of the elastic portion 102 away from the fixed portion 101 forms an adsorption end. The barrier structure is configured to open or close the vent 1021 to connect or disconnect the adsorption chamber with the atmosphere.

[0077] Illustratively, the barrier structure comprises a vacuum valve.

[0078] In some examples, the vacuum cup 1 is made of silicone, rubber, polyurethane, or a thermoplastic elastomer. For example, the vacuum cup 1 is made of silicone. This makes the vacuum cup 1 lighter, which can reduce the weight of the display module 100 and facilitate a thinner and lighter display module 100.

[0079] For example, the fixed end is bonded to the cover plate 20 or the support layer 30, and the adsorption end is adsorbed and connected to the fixed plate. The bonding force between the fixed end and the cover plate 20 or the support layer 30 is greater than the adsorption force between the adsorption end and the fixed plate. In this way, the display module 100 is adsorbed and connected to the fixed plate, and the disassembly and installation of the display module 100 and the fixed plate are very convenient. In the case where the position of the display module 100 needs to be changed, the display module 100 can be quickly removed from the current fixed plate and quickly installed on the fixed plate at the specified position, which is beneficial to improving the efficiency of the operator. For example, the fixed end is bonded to the cover plate 20 or the support layer 30 by pressure-sensitive adhesive, UV adhesive or double-sided adhesive.

[0080] Alternatively, for example, the fixed end is bonded to the fixed plate, and the suction end is suction-connected to the cover plate 20 or the support layer 30. The bonding force between the fixed end and the fixed plate is greater than the suction force between the suction end and the cover plate 20 or the support layer 30. In this way, the cover plate 20 or the support layer 30 is suction-connected to the vacuum suction cup 1, making it very convenient to remove and install the display panel 10 from the fixed plate. When maintenance or repair of the display panel 10 is required, the display panel 10 can be quickly removed from the fixed plate and quickly installed onto the fixed plate, which helps improve the efficiency of the operator.

[0081] In other embodiments, the elastic fixing member includes a spring, one end of which is connected to the fixing plate and one of the support layer 30 or the cover plate 20, and the other end is adsorbed and connected to the other of the fixing plate and the support layer 30 or the cover plate 20.

[0082] In some embodiments, as Figure 5A and Figure 6A As shown, the end of the second elastic fixing member 80 away from the cover plate 20 is flush with the end of the first elastic fixing member 70 away from the support layer 30. In this way, when the elastic fixing members undergo compressive elastic deformation, the compression amount of the first elastic fixing member 70 can be equal to the compression amount of the second elastic fixing member 80. This can make the elastic force of the first elastic fixing member 70 on the support layer 30 and the elastic force of the second elastic fixing member 80 on the cover plate 20 equal, which is beneficial to improving the force uniformity of the display module 100 and reducing the risk of damage to the display module 100.

[0083] In other embodiments, Figure 5B and Figure 6BAs shown, the end of the second elastic fixing member 80 away from the cover plate 20 is located on the side of the end of the first elastic fixing member 70 away from the supporting layer 30 away from the main body 11. In this way, when the elastic fixing member generates compressive elastic deformation, the compression amount of the first elastic fixing member 70 can be smaller than the compression amount of the second elastic fixing member 80, so that the elastic force of the first elastic fixing member 70 on the supporting layer 30 can be smaller than the elastic force of the second elastic fixing member 80 on the cover plate 20. In this way, the elastic force of the first elastic fixing member 70 on the supporting layer 30 is smaller, and the elastic force of the first elastic fixing member 70 on the main body 11 of the display panel 10 is smaller, which is conducive to reducing the risk of deformation of the display panel 10.

[0084] In some embodiments, the distance between the end of the second elastic fixing member 80 away from the cover plate 20 and the cover plate 20 is a first distance, and the distance between the end of the first elastic fixing member 70 away from the support layer 30 and the support layer 30 is a second distance. The ratio of the first distance to the second distance is greater than 1 and less than or equal to 1.5. That is, the ratio of the height of the second elastic fixing member 80 to the height of the first elastic fixing member 70 is greater than 1 and less than or equal to 1.5. In this way, the first distance is not too large, and the thickness of the display module 100 is not too thick.

[0085] In some embodiments, the elastic fixing member is a circular vacuum cup 1. The diameter of the vacuum cup 1 connected to the support layer 30 is larger than the diameter of the vacuum cup 1 connected to the cover plate 20. This smaller diameter of the vacuum cup 1 connected to the cover plate 20 allows the width of the portion of the cover plate 20 extending beyond the display panel 10 to be narrower, thereby reducing the bezel width of the display module 100.

[0086] In some examples, the diameter of the vacuum suction cup 1 connected to the support layer 30 is 2 mm to 6 mm. For example, the diameter of the vacuum suction cup 1 connected to the support layer 30 is 2 mm, 2.3 mm, 2.5 mm, 2.6 mm, 3 mm, 3.2 mm, 3.6 mm, 4 mm, 4.3 mm, 4.8 mm, 5 mm, 5.5 mm, or 6 mm.

[0087] The diameter of the vacuum suction cup 1 connected to the cover plate 20 is 1mm to 4mm. For example, the diameter of the vacuum suction cup 1 connected to the cover plate 20 is 1mm, 1.1mm, 1.2mm, 1.3mm, 1.4mm, 1.5mm, 1.6mm, 1.7mm, 1.9mm, 1.9mm,

[0088] 2mm, 2.1mm, 2.2mm, 2.3mm, 2.4mm, 2.5mm, 2.6mm, 2.7mm, 2.8mm, 2.9mm,

[0089] 3mm, 3.2mm, 3.5mm, 3.6mm, 3.8mm, 3.9mm, or 4mm.

[0090] In some embodiments, as Figure 2A As shown, the support layer 30 includes a first region 31, a second region 32, a third region 33, and a fourth region 34. The orthographic projection of the printed circuit board 40 on the reference plane is located within the orthographic projection of the first region 31 on the reference plane, and the reference plane is parallel to the display surface of the main body 11. The second region 32 is located on one side of the first region 31 along the first direction X, and the first direction X is parallel to the bending axis of the binding portion 12. The third region 33 is located on the side of the first region 31 away from the second region 32. The fourth region 34 is located on the side of the first region 31 away from the binding portion 12. The first elastic fixing member 70 is located in at least one of the second region 32, the third region 33, and the fourth region 34.

[0091] In some examples, such as Figure 2A As shown, the first elastic fixing member 70 is located in the second region 32 and the third region 33. The first elastic fixing member 70 in the second region 32 and the first elastic fixing member 70 in the third region 33 are symmetrically arranged about a first axis L1. The first axis L1 extends along the second direction Y and passes through the center of the first region 31. In this way, the force exerted on the support layer 30 by the first elastic fixing member 70 in the second region 32 and the force exerted on the support layer 30 by the first elastic fixing member 70 in the third region 33 are symmetrically arranged about the first axis L1, which can improve the uniformity of the force applied to the support layer 30 and facilitate the improvement of the service life of the support layer 30.

[0092] For example, the plurality of first elastic fixing members 70 in the second region 32 are arranged in a row at intervals along the second direction Y. The plurality of first elastic fixing members 70 in the third region 33 are arranged in a row at intervals along the second direction Y.

[0093] In some examples, such as Figure 2A As shown, the first elastic fixing member 70 is located in the fourth region 34. The first elastic fixing members 70 in the fourth region 34 are symmetrically arranged about the first axis L1. In this way, the force exerted by the first elastic fixing members 70 in the fourth region 34 on the support layer 30 is symmetrically arranged about the first axis L1, which can improve the uniformity of the force applied to the support layer 30 and help increase the service life of the support layer 30.

[0094] Exemplarily, the plurality of first elastic fixing members 70 in the fourth region 34 are arranged in multiple rows and columns, with each row including at least two first elastic fixing members 70 spaced apart along the first direction X. Each column includes at least two first elastic fixing members 70 spaced apart along the second direction Y. For example, the plurality of first elastic fixing members 70 in the fourth region 34 are arranged in three rows and eight columns.

[0095] In some examples, such as Figure 2AAs shown, the first elastic fixing member 70 is located in the second region 32, the third region 33, and the fourth region 34. The first elastic fixing member 70 in the second region 32 and the first elastic fixing member 70 in the third region 33 are symmetrically arranged about the first axis L1. The first elastic fixing member 70 in the fourth region 34 is symmetrically arranged about the first axis L1.

[0096] In some examples, the diameter of the vacuum chuck 1 in the second region 32 , the diameter of the vacuum chuck 1 in the third region 33 , and the diameter of the vacuum chuck 1 in the fourth region 34 are equal.

[0097] In some embodiments, as Figure 2B and Figure 2D As shown, the cover plate 20 includes a protection zone 21, a first frame zone 22, a second frame zone 23, a third frame zone 24 and a fourth frame zone 25. The orthographic projection of the protection zone 21 on the reference plane coincides with the orthographic projection of the display panel 10 on the reference plane. The first frame zone 22 is located on one side of the protection zone 21 along the second direction Y. The orthographic projection of the first frame zone 22 on the reference plane is located on the side of the orthographic projection of the binding portion 12 on the reference plane away from the orthographic projection of the printed circuit board 40 on the reference plane. The second frame zone 23 is located on the side of the protection zone 21 away from the first frame zone 22. The third frame zone 24 is located on the side of the protection zone 21 along the first direction X. The fourth frame zone 25 is located on the side of the protection zone 21 away from the third frame zone 24. The second elastic fixing member 80 is located in at least one of the first frame zone 22, the second frame zone 23, the third frame zone 24 and the fourth frame zone 25.

[0098] In some examples, such as Figure 2B and Figure 2D As shown, the second elastic fixing member 80 is located in the first frame area 22, the second frame area 23, the third frame area 24, and the fourth frame area 25. The maximum width of the second elastic fixing member 80 in the first frame area 22 along the second direction Y is smaller than the maximum width of the second elastic fixing member 80 in the second frame area 23 along the second direction Y, the maximum width of the second elastic fixing member 80 in the third frame area 24 along the first direction X, and the maximum width of the second elastic fixing member 80 in the fourth frame area 25 along the first direction X. In this way, the smaller maximum width of the second elastic fixing member 80 in the first frame area 22 along the second direction Y can make the width of the first frame area 22 smaller, which is beneficial for reducing the bottom frame of the display module 100.

[0099] Exemplarily, the maximum width of the second elastic fixing member 80 in the first frame area 22 along the second direction Y is 1 mm to 3 mm. For example, the maximum width of the second elastic fixing member 80 in the first frame area 22 along the second direction Y is 1 mm, 1.1 mm, 1.2 mm, 1.3 mm, 1.4 mm, 1.5 mm, 1.6 mm, 1.7 mm, 1.9 mm, 1.9 mm, 2 mm, 2.1 mm, 2.2 mm, 2.3 mm, 2.4 mm, 2.5 mm, 2.6 mm, 2.7 mm, 2.8 mm, 2.9 mm, or 3 mm.

[0100] The maximum width of the second elastic fixing member 80 in the second frame area 23 along the second direction Y is 1mm to 4mm. For example, the maximum width of the second elastic fixing member 80 in the second frame area 23 along the second direction Y is 1mm, 1.1mm, 1.2mm, 1.3mm, 1.4mm, 1.5mm, 1.6mm, 1.7mm, 1.9mm, 1.9mm, 2mm, 2.1mm, 2.2mm,

[0101] 2.3mm, 2.4mm, 2.5mm, 2.6mm, 2.7mm, 2.8mm, 2.9mm, 3mm, 3.2mm, 3.5mm, 3.6mm, 3.8mm, 3.9mm, or 4mm.

[0102] The maximum width of the second elastic fixing member 80 in the third frame area 24 along the second direction Y is 1 mm to 4 mm. For example, the maximum width of the second elastic fixing member 80 in the second frame area 23 along the second direction Y is 1 mm, 1.1 mm, 1.2 mm, 1.3 mm, 1.4 mm, 1.5 mm, 1.6 mm, 1.7 mm, 1.9 mm, 1.9 mm, 2 mm, 2.1 mm, 2.2 mm,

[0103] 2.3mm, 2.4mm, 2.5mm, 2.6mm, 2.7mm, 2.8mm, 2.9mm, 3mm, 3.2mm, 3.5mm,

[0104] 3.6mm, 3.8mm, 3.9mm, or 4mm.

[0105] The maximum width of the second elastic fixing member 80 in the fourth frame area 25 along the second direction Y is 1 mm to 4 mm. For example, the maximum width of the second elastic fixing member 80 in the second frame area 23 along the second direction Y is 1 mm, 1.1 mm, 1.2 mm, 1.3 mm, 1.4 mm, 1.5 mm, 1.6 mm, 1.7 mm, 1.9 mm, 1.9 mm, 2 mm, 2.1 mm, 2.2 mm,

[0106] 2.3mm, 2.4mm, 2.5mm, 2.6mm, 2.7mm, 2.8mm, 2.9mm, 3mm, 3.2mm, 3.5mm,

[0107] 3.6mm, 3.8mm, 3.9mm, or 4mm.

[0108] In some examples, such as Figure 2B and Figure 2D As shown, the second elastic fixing member 80 is located in the second frame area 23, the third frame area 24 and the fourth frame area 25. The maximum width of the second elastic fixing member 80 in the third frame area 24 along the first direction X, and the maximum width of the second elastic fixing member 80 in the fourth frame area 25 along the first direction X, are smaller than the maximum width of the second elastic fixing member 80 in the second frame area 23 along the second direction Y. In this way, the maximum width of the second elastic fixing member 80 in the third frame area 24 along the first direction X, and the maximum width of the second elastic fixing member 80 in the fourth frame area 25 along the first direction X are smaller, which can make the width of the third frame area 24 narrower and the width of the fourth frame area 25 smaller.

[0109] In some examples, such as Figure 2B As shown, the second elastic fixing member 80 is located in the third frame area 24 and the fourth frame area 25. The second elastic fixing member 80 of the third frame area 24 and the elastic fixing member of the fourth frame area 25 are symmetrical about the second axis L2. The second axis L2 extends along the second direction Y and passes through the center of the protection area 21. In this way, the force exerted by the second elastic fixing member 80 in the third frame area 24 on the support layer 30 and the force exerted by the second elastic fixing member 80 in the fourth frame area 25 on the support layer 30 are symmetrically arranged about the second axis L2, which can improve the uniformity of the force applied to the cover plate 20 and is conducive to improving the service life of the cover plate 20.

[0110] In some examples, such as Figure 2B and Figure 2D As shown, the second elastic fixing member 80 is located in the first border area 22. The second elastic fixing member 80 in the first border area 22 is the first target elastic fixing member. The first border area 22 includes a first sub-area 221 and a second sub-area 222. The first target elastic fixing member is located in the first sub-area 221, and the second sub-area 222 is located between the first sub-area 221 and the protection area 21. The first target elastic fixing member is not located in the second sub-area 222. In this way, the distance between the first target elastic fixing member and the binding portion 12 is larger, which can reduce the risk of collision between the first target elastic fixing member and the binding portion 12, thereby reducing the risk of damage to the binding portion 12.

[0111] In some embodiments, as Figure 2B and Figure 2DAs shown, the binding portion 12 includes a first sub-portion 121 and a second sub-portion 122. The first sub-portion 121 is connected to the printed circuit board 40. Along the first direction X, the ends of the first sub-portion 121 are retracted relative to the ends of the main portion 11. The second sub-portion 122 is located on the side of the first sub-portion 121 away from the printed circuit board 40. Along the first direction X, the ends of the second sub-portion 122 are flush with the ends of the main portion 11.

[0112] In some examples, such as Figure 2B and Figure 4 As shown, the orthographic projections of the first sub-portion 121 and the second sub-portion 122 on the reference surface do not overlap with the orthographic projection of the support layer 30 on the reference surface.

[0113] Exemplarily, the number of flexible circuit boards 50 and the number of driving chips 60 are equal, and one driving chip 60 is located on one flexible circuit board 50. For example, the display module 100 includes two flexible circuit boards 50 and two driving chips 60.

[0114] In other examples, such as Figure 2D 、 Figure 6A and Figure 6B As shown, the orthographic projection of the second sub-section 122 on the reference surface does not overlap with the orthographic projection of the support layer 30 on the reference surface, and the orthographic projection of the first sub-section 121 on the reference surface is located within the orthographic projection of the support layer 30 on the reference surface. At this time, the driver chip 60 is located on the first sub-section 121.

[0115] Exemplarily, the number of flexible circuit boards 50 and the number of driving chips 60 are not equal. For example, the display module 100 includes two flexible circuit boards 50 and three driving chips 60.

[0116] In some embodiments, as Figure 2B and Figure 2D As shown, the second elastic fixing member 80 is located in the third frame area 24, and the second elastic fixing member 80 in the third frame area 24 is the second target elastic fixing member. The third frame area 24 includes a third sub-area 241 and a fourth sub-area 242. The third sub-area 241 is located on one side of the first direction X of the printed circuit board 40 and the first sub-section 121, the second target elastic fixing member is located in the third sub-area 241, the fourth sub-area 242 is located on one side of the third sub-area 241 along the second direction Y, and is located on one side of the second sub-section 122 along the first direction X, and the second target elastic fixing member is not located in the fourth sub-area 242. In this way, the interval between the second target elastic fixing member and the binding portion 12 is larger, which can reduce the risk of the second target elastic fixing member colliding with the binding portion 12, thereby reducing the risk of damage to the binding portion 12.

[0117] In some embodiments, as Figure 2B and Figure 2DAs shown, the second elastic fixing member 80 is located in the fourth frame area 25, and the second elastic fixing member 80 in the fourth frame area 25 is the third target elastic fixing member. The fourth frame area 25 includes a fifth sub-area 251 and a sixth sub-area 252. The fifth sub-area 251 is located on one side of the printed circuit board 40 and the first sub-section 121 in the first direction X, and the third target elastic fixing member is located in the fifth sub-area 251. The sixth sub-area 252 is located on one side of the fifth sub-area 251 along the second direction Y, and on one side of the second sub-section 122 along the first direction X. The third target elastic fixing member is not located in the fourth sub-area 242. In this way, the distance between the third target elastic fixing member and the binding portion 12 is larger, which can reduce the risk of collision between the third target elastic fixing member and the binding portion 12, thereby reducing the risk of damage to the binding portion 12.

[0118] In some embodiments, as Figure 7B As shown, the display module 100 further includes a sensor 90, which is located on the vacuum suction cup 1 and connected to the display panel 10. The sensor 90 includes at least one of a pressure sensor 90, a humidity sensor 90, or a temperature sensor 90. In this way, the display module 100 can monitor the pressure of the vacuum suction cup 1, as well as the temperature and humidity around the display module 100, thereby reducing the risk of damage to the display module 100.

[0119] In some embodiments, as Figure 7B As shown, the display module 100 further includes a waterproof adhesive 110, which is disposed around the fixed end and in contact with the vacuum suction cup 1. Thus, on the one hand, the waterproof adhesive 110 can prevent water vapor from invading the fixed end, which is beneficial to improving the bonding strength at the fixed end.

[0120] In some examples, the waterproof glue 110 includes at least one of acrylic waterproof glue 110 , polyurethane waterproof glue 110 , silicone waterproof glue 110 , rubber waterproof glue 110 , and epoxy waterproof glue 110 .

[0121] In some embodiments, as Figure 3 As shown, the display module 100 further includes a first adhesive layer 120, which is positioned between the display panel 10 and the cover plate 20. The first adhesive layer 120 is used to bond the display panel 10 and the cover plate 20. For example, the material of the first adhesive layer 120 may include an optically clear adhesive (OCA) or a pressure-sensitive adhesive (PSA), or other adhesive material with high light transmittance (e.g., a light transmittance greater than or equal to 90%). For example, the material of the first adhesive layer 120 includes optical adhesive.

[0122] In some embodiments, as Figure 2A and Figure 8 As shown, the display module 100 also includes an ink layer 130, which is located between the display panel 10 and the cover plate 20. In the orthographic projection onto the reference plane, the ink layer 130 covers the first border area 22, the second border area 23, the third border area 24 and the fourth border area 25, and the ink layer 130 does not overlap with the display area A.

[0123] In some embodiments, as shown in the figure, the display module 100 further includes a polarizing layer 140 , and the polarizing layer 140 is located between the display panel 10 and the cover plate 20 .

[0124] In the description of this specification, specific features, structures, materials or characteristics may be combined in an appropriate manner in any one or more embodiments or examples.

[0125] The above description is merely a specific embodiment of the present disclosure, but the scope of protection of the present disclosure is not limited thereto. Any changes or substitutions that a person skilled in the art can conceive within the technical scope disclosed in the present disclosure should be included within the scope of protection of the present disclosure.
