[0050] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0051] In related technologies, in order to pursue a larger display size, multiple curved or irregularly shaped displays are often spliced ​​together to form a large screen on one side, which is widely used in various scenarios. However, existing curved screens and irregularly shaped spliced ​​screens have many problems or defects.

[0052] First, in the existing technology, if a larger curved screen is formed by splicing, each display screen to be spliced ​​is a curved display screen, which is complicated to manufacture and costly, and the splicing effect is limited.

[0053] Second, larger curved screens formed by splicing can only have specific shapes such as curved or spherical surfaces, and it is difficult to have irregular shapes.

[0054] Third, before a larger curved screen can be formed by splicing, a bracket with a specific curvature needs to be installed and fixed. Then, multiple curved screens are installed one by one on the bracket, which involves many and complex processes.

[0055] In view of this, embodiments of this application propose a display module and a display device, aiming to achieve the adjustability of the shape of the display module, thereby enabling the display module to have a wider range of applications.

[0056] Reference Figure 1 As shown, this application discloses a display module 10, which includes a support back plate 11, a flexible display panel 12, multiple supports 13, and a driving structure 14.

[0057] Specifically, the support backplate 11 mainly serves to support and connect other parts of the display module 10. The size of the support backplate 11 (referring to the area of ​​the support backplate 11) is adapted to the size of the flexible display panel 12 (referring to the area of ​​the flexible display panel 12). For example, the size of the support backplate 11 can be the same as the size of the flexible display panel 12, or the size of the support backplate 11 can be larger than the size of the flexible display panel 12. The material of the support backplate 11 can be stainless steel, etc.

[0058] Reference Figure 1As shown, the flexible display panel 12 is disposed on one side of the supporting back plate 11, and the light-emitting side of the flexible display panel 12 is opposite to the supporting back plate 11. In this embodiment, the flexible display panel 12 is a Mini-LED (Mini Light Emitting Diode) display panel. In other embodiments, the flexible display panel 12 may also include an OLED (Organic Light Emitting Diode) display panel, a QLED (Quantum Dot Light Emitting Diode) display panel, or even an LCD (liquid crystal display) panel, etc. It is understood that any area of ​​the flexible display panel 12 can be bent or folded.

[0059] Reference Figure 1 As shown, multiple supports 13 are disposed between the support back plate 11 and the flexible display panel 12, with one end of each support 13 connected to the support back plate 11 and the other end connected to the flexible display panel 12. The supports 13 are evenly distributed on the support back plate 11, meaning they are also evenly distributed relative to the flexible display panel 12. Therefore, if the flexible display panel 12 is divided into multiple regions, each region corresponds one-to-one with a support 13. In this embodiment, the distance between any two adjacent supports 13 is greater than or equal to 15mm and less than or equal to 25mm. For example, the distance between any two adjacent supports 13 can be 15mm, 18mm, 20mm, 22mm, 25mm, etc.

[0060] Simultaneously, the support 13 can deform along the normal direction of the support back plate 11, meaning the support 13 can at least elongate or contract along the normal direction of the support back plate 11. When the support 13 elongates along the normal direction of the support back plate 11, the distance between the corresponding area of ​​the flexible display panel 12 and the support back plate 11 increases; when the support 13 contracts along the normal direction of the support back plate 11, the distance between the corresponding area of ​​the flexible display panel 12 and the support back plate 11 decreases. Thus, by controlling the degree of deformation of different supports 13, the distance between each area of ​​the flexible display panel 12 and the support back plate 11 can be changed, thereby altering the overall shape of the flexible display panel 12. For example, when all supports 13 do not deform or undergo the same deformation, the flexible display panel 12 is flat; when all supports 13 deform to varying degrees, the flexible display panel 12 has an irregular shape.

[0061] Reference Figure 1As shown, the driving structure 14 can be disposed on the support backplate 11 (for illustration only), and the driving structure 14 is connected to multiple supports 13. The driving structure 14 is used to drive at least one support 13 to deform along the normal direction of the support backplate 11, thereby changing the distance between at least one area of ​​the flexible display panel 12 and the support backplate 11. In this way, the overall shape of the flexible display panel 12 can be adjusted by using the driving structure 14 to drive multiple supports 13 to produce deformations of different degrees or partially the same degree. For example, by using the driving structure 14 to make the support 13 closer to the edge of the support backplate 11 deform more, the flexible display panel 12 can be adjusted.

[0062] It forms a concave curved surface shape.

[0063] The display module provided in this application embodiment utilizes the driving structure 14 to drive the support 13 to deform, thus making the shape of the flexible display panel 12 no longer fixed. This means the shape of the flexible display panel 12 can be adjusted as needed, thereby increasing the application range of the display module 10. When this display module 10 is applied to a splicing display device, its shape can also be adjusted as needed, resulting in a better splicing effect and eliminating the need to consider the installation location during installation.

[0064] In one alternative implementation, refer to Figure 2 As shown in the embodiment of this application, a display module is also provided, in which the support 13 is configured as an airbag 131.

[0065] Specifically, the airbag 131 expands after being filled with gas, and in this embodiment, the airbag 131 mainly expands in the normal direction of the support back plate 11; and after the gas in the airbag 131 is released, the airbag 131 will shrink accordingly, so that the deformation of the support body 13 can be achieved.

[0066] At the same time, refer to Figure 2 As shown, the driving structure 14 includes an air pump 141, which has an air outlet 142. Each air outlet 142 corresponds to an airbag 131, and the air outlet 142 and the airbag 131 are connected by a pipe 143 (in this embodiment, the pipe 143 passes through the support back plate 11). The air pump 141 can fill the airbags 131 with gas through each air outlet 142. It is understood that in this embodiment, when the flexible display panel 12 is not deformed, the airbags 131 are all in an uninflated state. Therefore, by filling different volumes of gas into different airbags 131, the deformation degree of each airbag 131 can be made different, thereby achieving the adjustment of the shape of the flexible display panel 12.

[0067] In addition, refer to Figure 2 As shown, each pipe 143 is equipped with a valve 144 (not individually labeled in the figure, only for illustration). The valves 144 can be electromagnetic valves. When a valve 144 is open, an air pump 141 can inflate the airbag 131 through the pipe 143. When a valve 144 is closed, the air pump 141 cannot inflate the airbag 131. The drive structure 14 also includes a controller 145, which is connected to multiple valves 144. The controller 145 is used to open or close at least one valve 144. Thus, when inflating the airbag 131, because different airbags 131 deform to different degrees, when some airbags 131 reach the expected deformation level, the controller 145 can close the valve 144 corresponding to that airbag 131, preventing it from continuing to inflate. Airbags 131 that have not reached the expected deformation level can continue to be inflated.

[0068] The shape of the flexible display panel 12 can be changed by using the combination of airbag 131, air pump 141 and controller 144. The airbag 131 has a simple structure and is easier to use in practical applications.

[0069] At the same time, refer to Figure 2 As shown, each pipe 143 is equipped with a pressure sensor 146 (each pressure sensor 146 is not individually labeled in the figure, it is only for illustration). The pressure sensor 146 is used to measure the pressure value of the corresponding airbag 131. The controller 145 is connected to multiple pressure sensors 146. The controller 145 can receive the pressure values ​​measured by each pressure sensor 146 and open or close the corresponding valve 144 according to the pressure value. During the process of the air pump 141 inflating gas into the airbag 131, the pressure value inside the airbag 131 will continuously increase, and the pressure value inside the airbag 131 is directly proportional to the degree of deformation of the airbag 131, that is, the higher the pressure value inside the airbag 131, the greater the degree of deformation of the airbag 131. When the airbag 131 reaches the expected degree of deformation, the pressure value of the airbag 131 reaches the predetermined value. At this time, the controller 145 controls the corresponding valve 144 to close, so that the air pump 141 stops inflating gas into the airbag 131. The air pressure sensor 146 can be used to more precisely control the degree of deformation of the airbag 131, thereby better adjusting the overall shape of the flexible display panel 12.

[0070] In practical applications, the controller 145 can be a control circuit board (PCB), and the display module 10 is equipped with a power supply 15 that supplies power to the controller 145 and the air pump 141.

[0071] When using the display module 10, if it is necessary to make the flexible display panel 12 present a specific shape (that is, to transform the flat flexible display panel 12 into a curved or irregular shape), a corresponding command can be input to the controller 145 (the command includes the expected pressure value information of each airbag 131, etc.). Then, the controller 145 opens the valve 144 on the pipe 143 of the corresponding airbag 131 according to the command, and the air pump 141 inflates gas into each airbag 131. During the inflation process, the pressure sensor 146 on each airbag 131 will detect the pressure of the gas. The current pressure value of each airbag 131 is sent to the controller 145. The controller 145 controls the valve 144 to close or remain open based on the comparison between the current pressure value of each airbag 131 and the expected pressure value. For example, when the current pressure value of a certain airbag 131 reaches the expected pressure value, the controller 144 controls the valve 144 on the pipe 143 connected to that airbag 131 to close. This continues until the pressure of each airbag 131 reaches the expected pressure value. At this point, each airbag 131 has reached the expected degree of deformation, thereby completing the adjustment of the shape of the flexible display panel 12.

[0072] In one embodiment, the air pump 141 and the controller 145 can both be integrated on the side of the support back plate 11 away from the flexible display panel 12, thereby reducing the risk of damage to the display module 10 during transportation.

[0073] The bad situation.

[0074] In one embodiment, the airbag 131 is connected to the support back plate 11 and the flexible display panel 12 by an adhesive layer. The adhesive layer can conveniently achieve the fixed connection between the airbag 131, the support back plate 11 and the flexible display panel 12, and the adhesive layer can also make it easier to replace the airbag 131 when it is damaged.

[0075] It is understandable that the flexible display panel 12 will also present different shapes when the degree of deformation of the support 13 is different.

[0076] For example, refer to Figure 3 As shown, when the deformation of multiple supports 13 is the same, the distance between each area of ​​the flexible display panel 12 and the support back plate 11 is equal, and the flexible display panel 12 is flat.

[0077] For example, refer to Figure 4 As shown, when the deformation of the support 13 closer to the edge of the support back plate 11 is greater among the multiple supports 13, the distance between the area of ​​the flexible display panel 12 closer to the edge and the support back plate 11 is greater. At this time, the flexible display panel 12 has a concave arc shape (wherein...). Figure 5 This is a schematic diagram showing the bending of both sides of the flexible display panel 12. Figure 6 (A schematic diagram of the flexible display panel 12 bending on all four sides).

[0078] For example, refer to Figure 7 As shown, among the multiple supports 13, the support 13 closer to the edge of the support back plate 11 has a smaller degree of deformation, and the distance between the area of ​​the flexible display panel 12 closer to the edge and the support back plate 11 is smaller. At this time, the flexible display panel 12 has an outwardly convex arc shape (wherein...). Figure 8 This is a schematic diagram showing the bending of both sides of the flexible display panel 12. Figure 9 (A schematic diagram of the flexible display panel 12 bending on all four sides).

[0079] For example, refer to Figure 10 and Figure 11 As shown, among the multiple supports 13, when the degree of deformation of the supports 13 gradually increases from the first side to the second side of the support back plate 11 (the first and second sides of the support back plate 11 are arranged opposite each other), the distance between the area of ​​the flexible display panel 12 closer to the second side and the support back plate 11 is greater, and the flexible display panel 12 is sloped. Furthermore, if the difference in the degree of deformation among the supports 13 decreases from large to small, the flexible display panel 12 will be concave, such as... Figure 10 As shown; if the difference in the degree of deformation between the supports 13 increases from small to large, the flexible display panel 12 will be convex, as... Figure 11 As shown.

[0080] For example, refer to Figure 12 and Figure 13 As shown, among the multiple supports 13, when the degree of deformation of the supports 13 gradually decreases from the first side to the second side of the support back plate 11 (the first and second sides of the support back plate are arranged opposite each other), the distance between the area of ​​the flexible display panel 12 closer to the second side and the support back plate 11 is smaller, and the flexible display panel 12 is sloped. Furthermore, if the difference in the degree of deformation among the supports 11 decreases from large to small, the flexible display panel 12 will be concave, such as... Figure 12 As shown; if the difference in the degree of deformation between the supports 11 increases from small to large, the flexible display panel 12 will be convex, such as... Figure 13 As shown.

[0081] For example, refer to Figure 14 As shown, when the deformation degree of each support 13 is different, the distance between each area in the flexible display panel 12 and the support back plate 11 is also different, and the flexible display panel 12 is irregular in shape.

[0082] The display module 10 provided in this application embodiment achieves adjustable shape and increases the application range of the display module 10.

[0083] Based on the same inventive concept, this application discloses a display device, including at least one display module as described above in the embodiments of this application.

[0084] Specifically, the display device may include a television, a billboard, a laser printer with display capabilities, a vehicle, a large wall surface, a theater screen, or a stadium sign, etc.

[0085] In one alternative implementation, refer to Figure 15 As shown in the figure, this application provides a display device including at least two display modules 10, wherein a flexible display panel 12 of any one of the at least two display modules 10 is disposed adjacent to a flexible display panel 12 of at least one other display module.

[0086] Specifically, the display portion of the display device is formed by splicing together flexible display panels 12 of at least two display modules 10. That is, by displaying different content on different display modules 10, the complete content displayed by the display device can be composed. For example, the display device may include nine display modules 10, with one display module 10 located in the middle and the other eight display modules 10 arranged around it.

[0087] It should be noted that for regularly shaped splicing screens, the flexible display panels 12 of each display module 10 are the same size, and the flexible display panels 12 of adjacent display modules 10 have adjacent sides of the same length; while for irregularly shaped splicing screens, the flexible display panels 12 of different display modules 10 can be different in size, so it is sufficient that the flexible display panels 12 of two adjacent display modules 10 have adjacent sides.

[0088] At the same time, refer to Figure 15 As shown, the display device includes a support base 20 located on the backlight side of the display device. A connector 30 is provided between the support base 20 and each display module 10. The connector 30 can deform to change the tilt angle of the display module 10 relative to the support base 20. When the display portion of the display device needs to be curved, the tilt angle of some of the display modules 10 needs to be adjusted so that the flexible display panels 12 of multiple display modules 10 can be more closely fitted together.

[0089] Reference Figure 15 As shown, the display device also includes a plurality of driving devices 40, each driving device 40 corresponding to a connector 30, and the driving device 40 is connected to the corresponding connector 30. The driving device 40 is used to drive the corresponding connector 30 to deform.

[0090] When using this display device, if it is necessary to adjust the shape of the display part of the display device, it is only necessary to adjust the tilt angle of each display module 10 through each drive device 40 to achieve the shape adjustment of the display part of the display device; in this way, each display module 10 does not need to adjust the angle or position before splicing, making the installation and use of the display device more convenient.

[0091] In one embodiment, the connecting body 30 includes multiple connecting rods 31, each connecting rod 31 being connected to a different position on the display module 10. For example, the connecting rod 30 includes four connecting rods 31, which are respectively connected to the four corners of the display module 10. The length of the connecting rods 31 can be changed, that is, the connecting rods 31 themselves can extend and retract. By controlling the length of the four connecting rods 31, the tilt angle of the display module 10 can be changed (the ends of the connecting rods 31 are hinged to the display module 10). Meanwhile, the driving device 40 includes a motor, which is connected to the end of each connecting rod 31 away from the display module 10. The motor can drive each connecting rod 31 to extend or retract. Specifically, the connecting rod 31 may include a tube body and a rod body. The rod body is threadedly connected inside the tube body. By driving the tube body or the rod body to rotate by the motor, the rod body can be moved into or out of the tube body, thereby realizing the extension or retraction of the connecting rod 31. This allows for adjustment of the tilt angle of each display module 10, thereby better enabling splicing between display modules 10.

[0092] In one embodiment, the connector 30 includes multiple airbags 32, each airbag 32 connected to a different position on the display module 10. For example, the connector 30 includes four airbags 32, each connected to one of the four corners of the display module 10. The airbags 32 are inflatable, and the tilt angle of the display module 10 can be changed by controlling the degree of inflation of the four airbags 32. Simultaneously, the driving device includes an air pump connected to each airbag 32, capable of driving the inflation of each airbag 32. Specifically, the air pump can be connected to each airbag 32 through different air outlets, and valves are provided on the air outlets to control their opening and closing. Gas is pumped into each airbag 32 by the air pump, causing the airbags 32 to inflate to different degrees. This allows for adjustment of the tilt angle of each display module 10, thereby better achieving splicing between display modules 10.

[0093] It should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
