Description

Technical Field

[0001] The present application relates to the technical field of display equipment, and in particular to a display module and a display device. Background Art

[0002] A display module is a module used to display images or information. It is widely used in various electronic devices. It is mainly composed of display devices and is responsible for presenting images, text or other visual information to users.

[0003] In actual use, the display module often has a chaotic display or no display in the display area of ​​the display panel. Summary of the invention

[0004] The display module and the display device provided in the embodiments of the present application can reduce the probability of a chaotic display or no display in the display area thereof, thereby ensuring the normal display of the display module and the display device.

[0005] In a first aspect, an embodiment of the present application provides a display module, which includes a display panel, a backlight module, a first circuit board, a flexible circuit board, and a reinforcement structure. The backlight module is arranged on one side of the display panel, and the first circuit board is arranged on the side of the backlight module away from the display panel. The two ends of the flexible circuit board are respectively connected to the side of the first circuit board away from the backlight module and the side of the display panel away from the backlight module, and the reinforcement structure is arranged on the side of the flexible circuit board away from the backlight module. Among them, at least one of the display panel, the backlight module, and the first circuit board is separated from the reinforcement structure to form a limiting space, and the flexible circuit board is at least partially located inside the limiting space.

[0006] In a second aspect, an embodiment of the present application provides a display device, comprising the above-mentioned display module.

[0007] In the display module and the display device provided in the embodiments of the present application, the display module includes a display panel for image display, a backlight module for providing a uniform light source for the display panel, a first circuit board located on the side of the backlight module away from the display panel, and a flexible circuit board connecting the first circuit board and the display panel. Among them, the control IC in the display panel can be arranged on the first circuit board. During the testing process of the display module, the internal structure of the module will undergo a certain degree of thermal deformation, and the flexible circuit board will be pulled. Since the flexible circuit board crosses the backlight module and is connected to the display panel and the first circuit board, the bending structure formed by the flexible circuit board itself has a certain tendency to unfold. Coupled with the pulling force received by the flexible circuit board during the testing process, it is easy to cause the disconnection of the connection end between the flexible circuit board and the display panel. Further, in order to improve the connection strength between the flexible circuit board and the display panel and the first circuit board, and reduce the probability of disconnection between the flexible circuit board and the display panel and the first circuit board, the display module further includes a reinforcing structure. The reinforcing structure is arranged on the side of the flexible circuit board away from the backlight module. A limiting space is formed between the reinforcing structure and at least one of the display panel, the backlight module, and the first circuit board. At least part of the flexible circuit board is located inside the limiting space. By forming the limiting space, the flexible circuit board is limited to ensure the relative position relationship between the flexible circuit board and the display panel, the backlight module, and the first circuit board, thereby improving the connection strength between the flexible circuit board and the display panel and the first circuit board, reducing the probability of disconnection between the flexible circuit board and the display panel and the first circuit board, and ensuring the smooth transmission of signals and the normal display of the display module. At the same time, by arranging the reinforcing structure on the side of the flexible circuit board away from the backlight module, the reinforcing structure is located at the edge position in the display module and has no contact with the original internal structure in the display module, which can minimize the influence of the reinforcing structure on the original internal structure in the display module and reduce the interference with the original structure of the display module after the reinforcing structure is arranged.

[0030] A display module is a module used to display images or information, which is widely used in various electronic devices. It is mainly composed of a display device and is responsible for presenting images, texts, or other visual information to users.

[0031] During actual use, the display area of the display panel of the display module often shows chaos or no display.

[0032] In view of this, in a first aspect, please refer to Figures 1 to 3 , an embodiment of the present application provides a display module, which includes a display panel 10, a backlight module 20, a first circuit board 30, a flexible circuit board 40, and a reinforcing structure 50. The backlight module 20 is disposed on one side of the display panel 10, and the first circuit board 30 is disposed on the side of the backlight module 20 away from the display panel 10. Two ends of the flexible circuit board 40 are respectively connected to the side of the first circuit board 30 away from the backlight module 20 and the side of the display panel 10 away from the backlight module 20, and the reinforcing structure 50 is disposed on the side of the flexible circuit board 40 away from the backlight module 20. Among them, at least one of the display panel 10, the backlight module 20, and the first circuit board 30 forms a limiting space K1 at an interval from the reinforcing structure 50, and at least a part of the flexible circuit board 40 is located inside the limiting space K1.

[0033] The display module provided by the embodiments of the present application is used to display images or information, and can be applied to electronic products, such as devices like smartphones, tablets, laptops, TVs, etc., and can also be used in in-vehicle displays, such as in parts like the instrument panel or center console of a car.

[0034] The display module mainly includes a display panel 10 and a backlight module 20. The display panel 10 is the core component in the display module, used for image display, responsible for converting electrical signals into visible images, and managing color contrast and response speed. The backlight module 20 provides a uniform light source for the display panel 10 to ensure the display of image brightness and color.

[0035] For the display panel 10, the display panel 10 includes a control IC (Integrated Circuit), an array substrate 11, and a liquid crystal layer 12. The control IC receives digital signals from the device processor and converts them into analog voltage signals suitable for driving the array substrate 11 to manipulate the arrangement of liquid crystals in the liquid crystal layer 12, thereby controlling the brightness and color of each pixel.

[0036] In the embodiments of the present application, the first circuit board 30 can be provided with the control IC in the display panel 10. The first circuit board 30 and the backlight module 20 are arranged on both sides of the display panel 10. The first circuit board 30 and the array substrate 11 are connected through a flexible circuit board 40. One end of the flexible circuit board 40 is connected to the side of the first circuit board 30 facing away from the backlight module 20, and the other end is connected to the side of the array substrate 11 facing away from the backlight module 20. The flexible circuit board 40 and the first circuit board 30 can be connected by soldering, and the flexible circuit board 40 and the array substrate 11 can be connected by soldering.

[0037] During the actual use of the display module, it may be exposed to various complex environmental conditions, such as high temperature, high humidity, etc., and it is necessary to conduct HAST (Highly Accelerated Temperature and Humidity Stress Test) verification on the display module. During the HAST verification process of the display module, the internal structure of the module will undergo a certain degree of thermal deformation, and the flexible circuit board 40 is pulled. Since the flexible circuit board 40 spans across the backlight module 20 and is connected to the display panel 10 and the first circuit board 30, the bent structure formed by the flexible circuit board 40 itself has a certain tendency to unfold. Coupled with the pulling force on the flexible circuit board 40 during the test, it is easy to cause the connection end between the flexible circuit board 40 and the array substrate 11 to become detached. When the flexible circuit board 40 is detached from the array substrate 11, it will cause signal transmission interruption or unstable transmission, resulting in phenomena such as black screen, color screen, flickering, or no response in some display areas on the display panel 10.

[0038] For this, the display module in the embodiments of the present application includes a reinforcing structure 50. The reinforcing structure 50 is disposed on the side of the flexible circuit board 40 away from the backlight module 20. The reinforcing structure 50 is used to limit the flexible circuit board 40, and improve the connection strength between the flexible circuit board 40 and the first circuit board 30 and the connection strength between the flexible circuit board 40 and the array substrate 11. By disposing the reinforcing structure 50 on the side of the flexible circuit board 40 away from the backlight module 20, the reinforcing structure 50 is at the edge position in the display module and has no contact with the original internal structure in the display module, which can reduce the influence of the reinforcing structure 50 on the original internal structure in the display module to the greatest extent and reduce the interference with the original structure of the display module after the reinforcing structure 50 is provided.

[0039] Specifically, based on the fact that the first circuit board 30 and the array substrate 11 are respectively located on both sides of the backlight module 20, one end of the flexible circuit board 40 is connected to the side of the first circuit board 30 away from the backlight module 20, and the other end of the flexible circuit board 40 is connected to the side of the array substrate 11 away from the backlight module 20. By disposing the reinforcing structure 50 on the side of the flexible circuit board 40 away from the backlight module 20, the flexible circuit board 40 can be limited on the side away from the backlight module 20, so as to improve the relative position stability between the flexible circuit board 40 and the backlight module 20, thereby improving the relative position stability between the flexible circuit board 40 and the array substrate 11 and the first circuit board 30, and improving the connection strength between the flexible circuit board 40 and the array substrate 11 and the first circuit board 30.

[0040] Optionally, a limiting space K1 can be formed between the reinforcing structure 50 and the array substrate 11, and one end of the flexible circuit board 40 connected to the array substrate 11 is located inside the limiting space K1, so as to improve the connection strength between the flexible circuit board 40 and the array substrate 11. Or, a limiting space K1 can be formed between the reinforcing structure 50 and the first circuit board 30, and one end of the flexible circuit board 40 connected to the first circuit board 30 is located inside the limiting space K1, so as to improve the connection strength between the flexible circuit board 40 and the first circuit board 30. Or, a limiting space K1 can be formed between the reinforcing structure 50 and the backlight module 20, and the part of the flexible circuit board 40 spanning the backlight module 20 is located inside the limiting space K1, so as to limit the relative position relationship between the flexible circuit board 40 and the backlight module 20, thereby limiting the relative position relationship between the flexible circuit board 40 and the array substrate 11 and the first circuit board 30, and improving the connection stability between the flexible circuit board 40 and the array substrate 11 and the first circuit board 30.

[0041] In summary, in the display module provided in the embodiment of the present application, it includes a display panel 10 for image display, a backlight module 20 for providing a uniform light source for the display panel 10, a first circuit board 30 located on the side of the backlight module 20 away from the display panel 10, and a flexible circuit board 40 connecting the first circuit board 30 and the display panel 10. Among them, the control IC in the display panel 10 can be arranged on the first circuit board 30. Further, in order to improve the connection strength between the flexible circuit board 40 and the display panel 10 and the first circuit board 30, and reduce the probability of detachment between the flexible circuit board 40 and the display panel 10 and the first circuit board 30, the display module further includes a reinforcing structure 50. A limiting space K1 is formed between the reinforcing structure 50 and at least one of the display panel 10, the backlight module 20, and the first circuit board 30. At least a part of the flexible circuit board 40 is located inside the limiting space K1. By forming the limiting space K1, the flexible circuit board 40 is limited to ensure the relative positional relationship between the flexible circuit board 40 and the display panel 10, the backlight module 20, and the first circuit board 30, thereby improving the connection strength between the flexible circuit board 40 and the display panel 10 and the first circuit board 30, reducing the probability of detachment between the flexible circuit board 40 and the display panel 10 and the first circuit board 30, and ensuring the smooth transmission of signals and the normal display of the display module.

[0042] In some embodiments, please refer to Figures 4 to 6 , the flexible circuit board 40 includes a first connection portion 41 located on the side of the display panel 10 away from the backlight module 20, and the reinforcing structure 50 includes a first reinforcing portion 51 located on the side of the display panel 10 away from the backlight module 20. At least a part of the first connection portion 41 is clamped between the display panel 10 and the first reinforcing portion 51.

[0043] The first connection portion 41 on the flexible circuit board 40 is connected to the side of the array substrate 11 away from the backlight module 20. In the thickness direction Z of the display panel 10, the projections of the first connection portion 41 and the array substrate 11 partially overlap, so as to improve the connection stability between the first connection portion 41 and the array substrate 11 at the preliminary connection level of the first connection portion 41 and the array substrate 11.

[0044] The first reinforcing portion 51 is located on the side of the array substrate 11 away from the backlight module 20, and at least a part of the first connection portion 41 is clamped between the array substrate 11 and the first reinforcing portion 51. When the first connection portion 41 is connected to the array substrate 11, the first reinforcing portion 51 located on the side of the first connection portion 41 away from the array substrate 11 exerts a certain degree of force on the first connection portion 41, so that the connection between the first connection portion 41 and the array substrate 11 is tighter, thereby improving the connection strength between the first connection portion 41 and the array substrate 11 and reducing the probability of detachment between the first connection portion 41 and the array substrate 11.

[0045] In some embodiments, referring to Figures 4 to 6 , the display panel 10 includes an array substrate 11, and a first connection portion 41 is connected to a side of the array substrate 11 facing away from the backlight module 20. A first reinforcing portion 51 is disposed in contact with a surface of the first connection portion 41 facing away from the array substrate 11. And / or, the display module further includes a cover plate structure 60 disposed on a side of the display panel 10 facing away from the backlight module 20, and the first reinforcing portion 51 is disposed in contact with a surface of the cover plate structure 60 facing the display panel 10.

[0046] Optionally, a connection is formed between the first reinforcing portion 51 in the reinforcing structure 50 and the remaining structures in the reinforcing structure 50. That is to say, the reinforcing structure 50 further includes a structure that can exert a certain acting force on the first reinforcing portion 51. When a connection relationship is formed between the first reinforcing portion 51 in the reinforcing structure 50 and the remaining structures, the first reinforcing portion 51 can directly abut against a surface of the first connection portion 41 facing away from the array substrate 11, and the remaining structures exert an acting force on the first reinforcing portion 51 toward the first connection portion 41 so that the first reinforcing portion 51 generates a direct pressing force on the first connection portion 41, thereby achieving the effect of making the connection between the first connection portion 41 and the array substrate 11 tighter. Or, considering that when the first connection portion 41 is connected to the array substrate 11, it is not convenient for the first reinforcing portion 51 to be connected to the array substrate 11 again, the first reinforcing portion 51 can be connected to the cover plate structure 60 on a side of the display panel 10 facing away from the backlight module 20. The cover plate structure 60 exerts a certain acting force on the first reinforcing portion 51, and the first reinforcing portion 51 transmits the acting force generated by the cover plate structure 60 to the remaining structures in the reinforcing structure 50, and the remaining structures exert an indirect strengthening effect on the connection between the first connection portion 41 and the array substrate 11 to reduce the probability of detachment between the first connection portion 41 and the array substrate 11.

[0047] In some embodiments, referring to Figure 6 , the display module further includes a cover plate structure 60 disposed on a side of the display panel 10 facing away from the backlight module 20. The display panel 10 includes an array substrate 11, and a first connection portion 41 is connected to a side of the array substrate 11 facing the cover plate structure 60. The first reinforcing portion 51 is filled between the cover plate structure 60 and the first connection portion 41.

[0048] Optionally, no connection is formed between the first reinforcing portion 51 in the reinforcing structure 50 and the remaining structures in the reinforcing structure 50. That is to say, the first reinforcing portion 51 is provided separately, and only the first reinforcing portion 51 can exert an acting force on the first connection portion 41 to improve the connection strength between the first connection portion 41 and the array substrate 11.

[0049] Specifically, the cover plate structure 60 is disposed on the side of the display panel 10 facing away from the backlight module 20, and the cover plate structure 60 and the display panel 10 are adhesively fixed through an optical adhesive. Based on the setting of the optical adhesive layer, a certain distance is formed between the cover plate structure 60 and the display panel 10 in the thickness direction Z of the display panel 10. A certain gap is formed between the cover plate structure 60 and the area on the array substrate 11 connected to the first connection portion 41, and the first reinforcing portion 51 is filled between the cover plate structure 60 and the first connection portion 41.

[0050] Along the thickness direction Z of the display panel 10, one side of the first reinforcing portion 51 facing the cover plate structure 60 is in contact with the cover plate structure 60, and one side of the first reinforcing portion 51 facing the first connection portion 41 is in contact with the first connection portion 41. Based on the adhesive fixation between the cover plate structure 60 and the display panel 10, when the first reinforcing portion 51 is filled between the cover plate structure 60 and the first connection portion 41, the cover plate structure 60 generates a force that squeezes the first connection portion 41 on the first reinforcing portion 51, so that the connection between the first connection portion 41 and the array substrate 11 is tighter, thereby reducing the probability of detachment between the first connection portion 41 and the array substrate 11. Optionally, the connection between the first reinforcing portion 51 and the cover plate structure 60 is a welding connection, and the connection area between the first reinforcing portion 51 and the cover plate structure 60 is larger than the connection area between the first connection portion 41 and the array substrate 11.

[0051] In some embodiments, please refer to Figures 4 to 6 , the flexible circuit board 40 includes a second connection portion 42 located on the side of the first circuit board 30 facing away from the backlight module 20, and the reinforcing structure 50 includes a second reinforcing portion 52 located on the side of the first circuit board 30 facing away from the backlight module 20. At least a part of the second connection portion 42 is clamped between the first circuit board 30 and the second reinforcing portion 52.

[0052] The second connection portion 42 on the flexible circuit board 40 is connected to the side of the array substrate 11 facing away from the backlight module 20. In the thickness direction Z of the display panel 10, the projections of the second connection portion 42 and the array substrate 11 partially overlap, so as to improve the connection stability between the second connection portion 42 and the first circuit board 30 at the preliminary connection level between the second connection portion 42 and the array substrate 11.

[0053] The second reinforcing part 52 is located on the side of the first circuit board 30 away from the backlight module 20, and at least part of the second connecting part 42 is clamped between the first circuit board 30 and the second reinforcing part 52. When the second connecting part 42 is connected to the first circuit board 30, the second reinforcing part 52 on the side of the second connecting part 42 away from the first circuit board 30 has a certain effect on the first connecting part 41, so that the connection between the second connecting part 42 and the first circuit board 30 is tighter, thereby improving the connection strength between the second connecting part 42 and the first circuit board 30 and reducing the probability of detachment between the second connecting part 42 and the first circuit board 30.

[0054] In some embodiments, please refer to Figures 4 to 6 , the second reinforcing part 52 is arranged to abut against the surface of the second connecting part 42 away from the backlight module 20.

[0055] When the second reinforcing part 52 is in contact with the second connecting part 42, the second reinforcing part 52 generates a certain degree of pressing force on the second connecting part 42 to press the second connecting part 42 against the first circuit board 30, thereby improving the connection strength between the second connecting part 42 and the first circuit board 30.

[0056] In some embodiments, please refer to Figure 6 and Figure 7 , the second reinforcing part 52 includes a conductive structure. The second reinforcing part 52 is connected to the first circuit board 30, and the orthographic projection of the connection area between the second reinforcing part 52 and the first circuit board 30 on the display panel 10 is located outside the orthographic projection of the second connecting part 42 on the display panel 10.

[0057] When the second reinforcing part 52 abuts against the side of the second connecting part 42 away from the backlight module 20, one end of the second reinforcing part 52 is connected to the first circuit board 30. Through the connection between the second reinforcing part 52 and the first circuit board 30, a pressing force is generated between the second reinforcing part 52 and the second connecting part 42.

[0058] Considering that the second connecting portion 42 has been connected to the first circuit board 30, the orthographic projection of the connection area between the second reinforcing portion 52 and the first circuit board 30 on the display panel 10 is arranged outside the orthographic projection of the second connecting portion 42 on the display panel 10, so as to facilitate the connection between the second reinforcing portion 52 and the first circuit board 30. At the same time, the acting position where the first circuit board 30 applies a force to the second reinforcing portion 52 is the connection position between the first circuit board 30 and the second reinforcing portion 52, and the acting position where the second reinforcing portion 52 applies a force to the second connecting portion 42 is the contact setting between the second reinforcing portion 52 and the second connecting portion 42. Through the above, the acting force position of the first circuit board 30 on the second reinforcing portion 52 and the acting force position between the second reinforcing portion 52 and the second connecting portion 42 can be arranged at intervals. While facilitating the connection of the second reinforcing portion 52 to the first circuit board 30, it can also facilitate the crimping between the second reinforcing portion and the second connecting portion 42. Optionally, the connection between the second reinforcing portion 52 and the first circuit board 30 is a welding connection, and the connection area between the second reinforcing portion 52 and the first circuit board 30 is larger than the connection area between the second connecting portion 42 and the first circuit board 30. Or, the second reinforcing portion 52 and the first circuit board 30 can also be connected by means of screw connection.

[0059] Optionally, when both the second reinforcing portion 52 and the second connecting portion 42 are connected to the first circuit board 30, the number of the second reinforcing portions 52 is equal to the number of the second connecting portions 42, and the second reinforcing portions 52 and the second connecting portions 42 are arranged in one-to-one correspondence. Exemplarily, when there are two second connecting portions 42, there are also two second reinforcing portions 52.

[0060] Considering the connection between the second reinforcing portion 52 and the first circuit board 30, a control IC of the display panel 10 can be arranged on the first circuit board 30. The second reinforcing portion 52 can be set as a conductive structure, and the signal transmission on the first circuit board 30 can be transmitted through the second reinforcing portion 52, providing parallel lines for signal transmission and improving the stability of signal transmission.

[0061] In some embodiments, please refer to Figure 4 , the second reinforcing portion 52 includes a conductive structure. The display module further includes a second circuit board 70 arranged on the side of the backlight module 20 away from the display panel 10. The orthographic projection of the second circuit board 70 on the display panel 10 is located outside the orthographic projection of the first circuit board 30 on the display panel 10, and the second reinforcing portion 52 is connected to the second circuit board 70.

[0062] During the actual production process, relevant circuit structures are usually already provided on the first circuit board 30. To reduce the impact of the second reinforcing portion 52 on the original structures on the first circuit board 30, a second circuit board 70 can be additionally provided in the display module, and the second reinforcing portion 52 is connected to the second circuit board 70. Similarly, relevant circuit structures can also be provided on the second circuit board 70. The second reinforcing portion 52 includes a conductive structure, and the signal transmission on the second circuit board 70 can be transmitted through the second reinforcing portion 52. Optionally, the connection between the second reinforcing portion 52 and the second circuit board 70 can be a welded connection or a screw connection, and the connection area between the second reinforcing portion 52 and the second circuit board 70 is larger than the connection area between the second connecting portion 42 and the first circuit board 30.

[0063] In some embodiments, referring to Figure 4 , the display module further includes a touch layer 61 disposed on the side of the display panel 10 facing away from the backlight module 20. The reinforcing structure 50 further includes a first reinforcing portion 51 connected to the touch layer 61. The first reinforcing portion 51 includes a conductive structure and is electrically connected between the second reinforcing portion 52 and the touch layer 61.

[0064] When the second reinforcing portion 52 is connected to the first circuit board 30 or the second circuit board 70, the second reinforcing portion 52 includes a conductive structure, and the touch IC of the touch layer 61 can be disposed on the first circuit board 30 and the second circuit board 70. Further, the first reinforcing portion 51 also includes a conductive structure and is electrically connected between the second reinforcing portion 52 and the touch layer 61, so that the touch signal can be transmitted through the second reinforcing portion 52 and the first reinforcement. Optionally, the touch layer 61 and the cover plate structure 60 can be integrated into the same layer structure.

[0065] In some embodiments, referring to Figure 4 and Figure 5 , the flexible circuit board 40 includes a first connecting portion 41 located on the side of the display panel 10 facing away from the backlight module 20, a second connecting portion 42 located on the side of the first circuit board 30 facing away from the backlight module 20, and a third connecting portion 43 connecting the first connecting portion 41 and the second connecting portion 42. The reinforcing structure 50 includes a third reinforcing portion 53 disposed on the peripheral side of the backlight module 20, and at least a part of the third connecting portion 43 is clamped between the backlight module 20 and the third reinforcing portion 53.

[0066] When the flexible circuit board 40 is connected between the display panel 10 and the first circuit board 30 on both sides of the backlight module 20, the flexible circuit board 40 as a whole forms a U-shaped structure, with the U-shaped opening facing the backlight module 20, and the backlight module 20 and the array substrate 11 are located inside the U-shaped structure. Correspondingly, the flexible circuit board 40 includes a first connection portion 41 on the side of the display panel 10 facing away from the backlight module 20, a second connection portion 42 on the side of the first circuit board 30 facing away from the backlight module 20, and a third connection portion 43 connecting the first connection portion 41 and the second connection portion 42, and the third connection portion 43 straddles the backlight module 20.

[0067] In order to limit the relative position between the third connection portion 43 and the backlight module 20, the reinforcing structure 50 includes a third reinforcing portion 53 provided on the peripheral side of the backlight module 20, and the third connection portion 43 is located between the backlight module 20 and the third reinforcing portion 53. The third reinforcement is on the side of the third connection portion 43 facing away from the backlight module 20, forming a limit on the third connection portion 43, reducing the probability of the third connection portion 43 shifting along the side away from the backlight module 20, thereby reducing the pulling force of the third connection portion 43 on the first connection portion 41 and the second connection portion 42, so as to ensure the relative position relationship between the first connection portion 41 and the array substrate 11 and between the second connection portion 42 and the first circuit board 30, thereby reducing the probability of detachment between the first connection portion 41 and the array substrate 11 and between the second connection portion 42 and the first circuit board 30.

[0068] In some embodiments, please refer to Figure 4 and Figure 5 , the third reinforcing portion 53 is arranged to abut against the surface of the third connection portion 43 facing away from the backlight module 20.

[0069] When the third reinforcing portion 53 contacts the third connection portion 43, the third reinforcing portion 53 generates a certain degree of pressing force on the third connection portion 43 to form a limit on the third connection portion 43, reducing the probability of the third connection portion 43 shifting along the side away from the backlight module 20, thereby reducing the pulling effect of the third connection portion 43 on the first connection portion 41 and the second connection portion 42, so as to ensure the relative position relationship between the first connection portion 41 and the array substrate 11 and between the second connection portion 42 and the first circuit board 30, thereby reducing the probability of detachment between the first connection portion 41 and the array substrate 11 and between the second connection portion 42 and the first circuit board 30.

[0070] In some embodiments, please refer to Figure 4 and Figure 5, the reinforcement structure 50 further includes a first reinforcement portion 51 located on the side of the display panel 10 away from the backlight module 20 and a second reinforcement portion 52 located on the side of the first circuit board 30 away from the backlight module 20. At least a part of the first connection portion 41 is clamped between the first reinforcement portion 51 and the display panel 10, and at least a part of the second connection portion 42 is clamped between the second reinforcement portion 52 and the first circuit board 30. Two ends of the third reinforcement portion 53 are respectively connected to the first reinforcement portion 51 and the second reinforcement portion 52.

[0071] The first reinforcement portion 51 is located on the side of the display panel 10 away from the backlight module 20, and the first reinforcement portion 51 is connected to the third reinforcement portion 53. That is to say, in the thickness direction Z of the display panel 10, the projection of the first reinforcement portion 51 is located on the side of the projection of the third reinforcement portion 53 facing the backlight module 20. The connection between the first reinforcement portion 51 and the third reinforcement portion 53 can generate a force on the third reinforcement portion 53 towards the backlight module 20 through the first reinforcement portion 51, so that the third reinforcement portion 53 has a tendency to displace towards the third connection portion 43, thereby improving the limiting effect of the third reinforcement portion 53 on the third connection portion 43. Similarly, the setting position of the second reinforcement portion 52 is for the same reason and will not be elaborated here.

[0072] In some embodiments, please refer to Figure 4 , the display module further includes a cover plate structure 60 disposed on the side of the display panel 10 away from the backlight module 20. The display panel 10 includes an array substrate 11. The first connection portion 41 is connected to the side of the array substrate 11 away from the backlight module 20, and the first reinforcement portion 51 is abutted against the surface of the cover plate structure 60 facing the array substrate 11. The second reinforcement portion 52 is abutted against the surface of the second connection portion 42 away from the backlight module 20. The third reinforcement portion 53 is abutted against the surface of the third connection portion 43 away from the backlight module 20.

[0073] When the cover plate structure 60 is bonded to the display panel 10 through an optical adhesive, the first reinforcement portion 51 in the reinforcement structure 50 can be connected to the side of the cover plate structure 60 facing the display panel 10. The second reinforcement portion 52 is abutted against the surface of the second connection portion 42 away from the array substrate 11, and the third reinforcement is abutted against the surface of the third connection portion 43 away from the backlight module 20. The first reinforcement portion 51, the second reinforcement portion 52, and the third reinforcement portion 53 are disposed around the sides of the first connection portion 41, the second connection portion 42, and the third connection portion 43 away from the backlight module 20. The reinforcement structure 50 forms an all-round reinforcement for the flexible circuit board 40, improving the connection strength between the flexible circuit board 40, the array substrate 11, and the first circuit board 30.

[0074] In some embodiments, please refer to Figure 4, the first connecting portion 41 extends along the first direction X, and the third connecting portion 43 is located on one side of the backlight module 20 along the first direction X. The first reinforcing portion 51 extends along the first direction X. One end of the first connecting portion 41 away from the third connecting portion 43 extends beyond one end of the first reinforcing portion 51 away from the third reinforcing portion 53 in the first direction X. The first direction X intersects with the thickness direction Z of the display panel 10.

[0075] In the actual manufacturing process of the display module, the first connecting portion 41 is connected to the array substrate 11 and is located on the side of the array substrate 11 facing away from the backlight module 20. After the first connecting portion 41 extends along the first direction X to partially overlap with the array substrate 11, considering the other structures provided on the array substrate 11 along the first direction X, the first connecting portion 41 should not extend too much. After the connection between the first connecting portion 41 and the array substrate 11 can be achieved, it is possible to take into account the avoidance of the other structures.

[0076] Furthermore, when the first strengthening portion strengthens the connection strength between the first connecting portion 41 and the array substrate 11, in order to reduce the influence of the first strengthening portion on the original structure arrangement, one end of the first strengthening portion away from the third strengthening portion is arranged on the side of one end of the first connecting portion 41 away from the third connecting portion 43 facing away from the backlight module 20. That is to say, in the thickness direction Z of the display panel 10, the size of the projection of the first strengthening portion in the first direction X is smaller than the size of the projection of the first connecting portion 41 in the first direction X, reducing the probability of structural interference of the first strengthening portion with the original structure arrangement, so that while the first strengthening portion realizes the strengthening effect, the influence on the original structure arrangement is reduced.

[0077] In some embodiments, please refer to Figure 4 , the second connecting portion 42 extends along the first direction X, and the third connecting portion 43 is located on one side of the backlight module 20 along the first direction X. The second reinforcing portion 52 extends along the first direction X. One end of the second reinforcing portion 52 away from the third reinforcing portion 53 extends beyond one end of the second connecting portion 42 away from the third connecting portion 43 in the first direction X. The first direction X intersects with the thickness direction Z of the display panel 10.

[0078] In the actual manufacturing process of the display module, the second connecting portion 42 is connected to the first circuit board 30. The first circuit board 30 is located on the side of the backlight module 20 away from the display panel 10. The structure on the side of the backlight module 20 away from the display panel 10 is relatively simple. To ensure the reinforcement effect of the second reinforcing portion 52 on the second connecting portion 42, one end of the second reinforcing portion 52 away from the third reinforcing portion 53 is disposed on the side of the second connecting portion 42 away from the third connecting portion 43 and away from the third connecting portion 43. That is to say, in the thickness direction Z of the display panel 10, the size of the projection of the second reinforcing portion 52 along the first direction X is greater than the size of the second connecting portion 42 along the first direction X, so as to realize the coverage of the second reinforcing portion 52 on the second connecting portion 42, ensure the reinforcement effect of the second reinforcing portion 52 on the second connecting portion 42, and improve the connection strength between the second connecting portion 42 and the first circuit board 30.

[0079] In some embodiments, please refer to Figure 4 , the display module further includes a second circuit board 70 disposed on the side of the backlight module 20 away from the display panel 10. The second circuit board 70 is located on the side of the first circuit board 30 away from the third connecting portion 43 along the first direction X. The second reinforcing portion 52 includes a first portion 521 connected to the third reinforcing portion 53 and abutting against the second connecting portion 42 and a second portion 522 connected between the first portion 521 and the second circuit board 70. The surface of the second circuit board 70 away from the backlight module 20 is located between the surface of the first circuit board 30 away from the backlight module 20 and the backlight module 20.

[0080] After the second reinforcing portion 52 covers the second connecting portion 42 in the first direction X, in order to facilitate the connection of the second reinforcing portion 52, a second circuit board 70 is additionally provided to connect the second reinforcing portion 52 to the second circuit board 70. Corresponding to the end of the second reinforcing portion 52 away from the third reinforcing portion 53 protruding beyond the end of the second connecting portion 42 away from the third connecting portion 43 in the first direction X, the second circuit board 70 is disposed on the side of the first circuit board 30 away from the third connecting portion 43 along the first direction X, so that the end of the second reinforcing portion 52 away from the third reinforcing portion 53 corresponds to the second circuit board 70, facilitating the connection between the second reinforcing portion 52 and the second circuit board 70.

[0081] Further, the second reinforcing portion 52 includes a first portion 521 connected to the third reinforcing portion 53 and abutting against the second connecting portion 42 and a second portion 522 connecting the first portion 521 and the second circuit board 70. That is to say, the first portion 521 abuts against the second connecting portion 42 and applies a force to the second connecting portion 42, and the end of the second portion 522 away from the first portion 521 is connected to the second circuit board 70.

[0082] In order to improve the acting force of the first part 521 on the second connecting part 42, the surface of the second circuit board 70 facing away from the backlight module 20 is disposed between the surface of the first circuit board 30 facing away from the backlight module 20 and the backlight module 20. That is to say, when one end of the second part 522 far from the first part 521 is connected to the second circuit board 70, at least part of the second part 522 is located on the side of the first part 521 facing the backlight module 20, and the second part 522 generates an acting force on the first part 521 toward the side of the backlight module 20, thereby strengthening the contact acting force of the first part 521 on the second connecting part 42 and improving the connection strength between the second connecting part 42 and the first circuit board 30.

[0083] In some embodiments, please refer to Figure 5 , the first reinforcing part 51 is disposed in contact with the surface of the first connecting part 41 facing away from the backlight module 20, the second reinforcing part 52 is disposed in contact with the surface of the second connecting part 42 facing away from the backlight module 20, and the third reinforcing part 53 is disposed in contact with the surface of the third connecting part 43 facing away from the backlight module 20. The first reinforcing part 51 at least partially covers the first connecting part 41 in the thickness direction Z of the display panel 10, and the second reinforcing part 52 at least partially covers the second connecting part 42 in the thickness direction Z of the display panel 10.

[0084] The first reinforcing part 51 in the reinforcing structure 50 is disposed in contact with the surface of the first connecting part 41 facing away from the backlight module 20, the second reinforcing part 52 is disposed in contact with the surface of the second connecting part 42 facing away from the backlight module 20, and the third reinforcing part 53 is disposed in contact with the surface of the third connecting part 43 facing away from the backlight module 20. The shape structure of the reinforcing structure 50 itself can be used to act on the first connecting part 41, the second connecting part 42, and the third connecting part 43, so as to realize the reinforcing effect of the reinforcing structure 50 on the flexible circuit board 40.

[0085] Both ends of the flexible circuit board 40 are respectively connected to the array substrate 11 and the first circuit board 30. The positions where detachment is likely to occur are the connection positions. Therefore, key settings are made at the positions of the first connecting part 41 and the second connecting part 42. At least part of the first reinforcing part 51 covers the first connecting part 41, and at least part of the second reinforcing part 52 covers the second connecting part 42. By using the self-structure of the reinforcing structure 50, the first reinforcing part 51 is pressed against the first connecting part 41 on the side of the first connecting part 41 facing away from the array substrate 11, and the second reinforcing part 52 is pressed against the second connecting part 42 on the side of the second connecting part 42 facing away from the first circuit board 30. Preferably, the contact between the first reinforcing part 51 and the first connecting part 41 and the contact between the second reinforcing part 52 and the second connecting part 42 form an interference clamping based on the setting of the third reinforcing part 53, so as to reduce the probability of detachment between the first connecting part 41 and the array substrate 11 and between the second connecting part 42 and the first circuit board 30.

[0086] In some embodiments, see Figure 5 An end of the second reinforcing portion 52 away from the third reinforcing portion 53 is protruded from an end of the first reinforcing portion 51 away from the third reinforcing portion 53 in a direction away from the third reinforcing portion 53 .

[0087] In the actual preparation of the display module, the first connecting portion 41 is connected to the array substrate 11, and the second connecting portion 42 is connected to the first circuit board 30. Relatively more remaining structures need to be arranged at the position where the first reinforcement portion 51 is arranged, and relatively fewer remaining structures need to be arranged at the position where the second reinforcement portion 52 is arranged. In order to achieve the reinforcement effect of the reinforcement structure 50 on the flexible circuit board 40 while reducing the influence of the reinforcement structure 50 on the original structure, the end of the second reinforcement portion 52 away from the third reinforcement portion 53 is arranged to protrude in the direction away from the third reinforcement portion 53 from the end of the first reinforcement portion 51 away from the third reinforcement portion 53, and a larger avoidance space is formed at the position of the first reinforcement portion 51 to facilitate the arrangement of the original remaining structures.

[0088] In some embodiments, see Figure 5 The first reinforcing portion 51 includes a first connecting section 511 connected to the third reinforcing portion 53 and a first reinforcing section 512 connected to the side of the first connecting section 511 facing away from the third reinforcing portion 53, and a side surface of the first reinforcing section 512 facing away from the first connecting portion 41 protrudes from a side surface of the first connecting section 511 facing away from the first connecting portion 41. And / or, the second reinforcing portion 52 includes a second connecting section 523 connected to the third reinforcing portion 53 and a second reinforcing section 524 connected to the side of the second connecting section 523 facing away from the third reinforcing portion 53, and a side surface of the second reinforcing section 524 facing away from the second connecting portion 42 protrudes from a side surface of the second connecting section 523 facing away from the first connecting portion 41.

[0089] In the clamping of the flexible circuit board 40 by the structural design of the reinforcement structure 50, the first reinforcement part 51 provides the main force for clamping the first connection part 41 and the second reinforcement part 52 provides the main force for clamping the second connection part 42. In order to make the first reinforcement part 51 clamp the first connection part 41 well, a first reinforcement section 512 with a thicker thickness is formed in the first reinforcement part 51, and the first reinforcement section 512 is located at the end of the first reinforcement part 51 away from the third reinforcement part 53. By thickening the first reinforcement section 512, the strength of the end of the first reinforcement part 51 away from the third reinforcement part 53 can be improved, and the clamping effect of the first reinforcement part 51 on the first connection part 41 can be improved. Furthermore, the projection of the first reinforcement section 512 in the thickness direction Z of the display panel 10 overlaps with the projection of the first connection part 41 in the thickness direction Z of the display panel 10. The second reinforcement section 524 in the second reinforcement part 52 is set for the same reason, which will not be repeated here.

[0090] In some embodiments, referring to Figure 5 , at one end of the first reinforcing portion 51 away from the third reinforcing portion 53, a first rounded corner Y1 is provided on the side of the first reinforcing portion 51 facing the first connecting portion 41. When the reinforcing structure 50 is connected to the side of the flexible circuit board 40 facing away from the backlight module 20, the first rounded corner Y1 can guide the contact between the first reinforcing portion 51 and the first connecting portion 41, while reducing the damage of the first reinforcing portion 51 to the first connecting portion 41 and facilitating the connection between the first reinforcing portion 51 and the first connecting portion 41.

[0091] In some embodiments, referring to Figure 5 , at one end of the first reinforcing portion 51 away from the third reinforcing portion 53, a second rounded corner Y2 is provided on the side of the first reinforcing portion 51 facing away from the first connecting portion 41. After the reinforcing structure 50 is connected to the side of the flexible circuit board 40 facing away from the backlight module 20, the position in the reinforcing structure 50 that is most likely to interfere with the remaining structures is the side of the first reinforcing portion 51 facing away from the first connecting portion 41 at one end of the first reinforcing portion 51 away from the third reinforcing portion 53. By setting this position as a rounded corner, a certain amount of avoidance can be achieved, reducing the influence of the first reinforcing portion 51 on the original structure.

[0092] In some embodiments, referring to Figure 5 , at one end of the second reinforcing portion 52 away from the third reinforcing portion 53, a third rounded corner Y3 is formed on the side of the second reinforcing portion 52 facing the second connecting portion 42. At one end of the second reinforcing portion 52 away from the third reinforcing portion 53, a fourth rounded corner Y4 is formed on the side of the second reinforcing portion 52 facing away from the second connecting portion 42. The setting method and beneficial effects of the third rounded corner Y3 are similar to those of the first rounded corner Y1, and the setting method and beneficial effects of the fourth rounded corner Y4 are similar to those of the second rounded corner Y2, and will not be elaborated here.

[0093] In some embodiments, referring to Figure 5 , the first connecting portion 41 extends along the first direction X, and the third connecting portion 43 is located on one side of the backlight module 20 along the first direction X. The first reinforcing portion 51 extends along the first direction X, and one end of the first reinforcing portion 51 away from the third reinforcing portion 53 extends beyond one end of the first connecting portion 41 away from the third connecting portion 43 in the first direction X, and the first direction X intersects with the thickness direction Z of the display panel 10. And / or, the second connecting portion 42 extends along the first direction X, and the third connecting portion 43 is located on one side of the backlight module 20 along the first direction X. The second reinforcing portion 52 extends along the first direction X, and one end of the second reinforcing portion 52 away from the third reinforcing portion 53 extends beyond one end of the second connecting portion 42 away from the third connecting portion 43 in the first direction X, and the first direction X intersects with the thickness direction Z of the display panel 10.

[0094] To ensure the strengthening effect of the first reinforcement part 51 on the connection strength between the first connection part 41 and the array substrate 11, one end of the first reinforcement part 51 far from the third reinforcement part 53 is set to extend beyond one end of the first connection part 41 far from the third connection part 43 in the first direction X. That is to say, the first reinforcement part 51 covers the first connection part 41 along the first direction X, so that the first reinforcement part 51 is in full contact with the first connection part 41 along the first direction X. The first reinforcement part 51 forms contacts at various positions on the first connection part 41 to reinforce the connection positions between the first connection part 41 and the array substrate 11 along the first direction X, and improve the connection strength between the first connection part 41 and the array substrate 11. The setting method and beneficial effects of the second reinforcement part 52 and the second connection part 42 are similar to those of the first reinforcement part 51 and the first connection part 41, and will not be elaborated here.

[0095] In a second aspect, an embodiment of the present application provides a display device. The display device includes all the technical features of the display module provided in the first aspect of the embodiments of the present application. Therefore, the display device includes all the beneficial effects of the display module provided in the first aspect of the embodiments of the present application, and will not be elaborated here.

[0096] Although the present invention has been described with reference to the preferred embodiments, various improvements can be made to it and components therein can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various technical features mentioned in each embodiment can be combined in any way.
