[0034] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with reference to specific embodiments in conjunction with the accompanying drawings.

[0035] The splicable display device provided in the embodiment of the present application is used to achieve the overlapping of display modules by adjusting the display surface angle and the position in three-dimensional space of the display modules, and the splicable display device is suitable for display modules of flat display and curved display.

[0036] Specifically, see Figure 1In the embodiment shown in the figure, the display module 1 adopts an LCD display unit or an OLED display unit, and the display module 1 includes a display panel 11 and a back panel unit 12 arranged on the back of the display panel 11. At least one side of the back panel unit 12 is located inside the side of the corresponding display panel 11, so as to form an overlapping area a at the edge of the back of the display panel 11. The overlapping area a is used for the display panel of another display module to be overlapped with the display module 1 to abut against it, and make the display panel of another display module abut against the side of the back panel unit 12. For example, in Figure 1 The back side, the upper side and the right side of the display panel 11 are both provided with overlapping areas a.

[0037] In this embodiment, the curvature of the display surface of the display module 1 is adjustable, for example, it can be converted from a curved display to a flat display, or between different curvatures. By adjusting the curvature of the display module 1, it is possible to achieve stacking with other display modules with curved displays. There are many types of curvature adjustment structures for adjusting the curvature of the display surface, for example, Figure 1 As shown, the curvature adjustment structure 13 is arranged on the back of the back plate unit 12, which is, for example, an adjustment hinge structure. Of course, in practical applications, other device structures that can achieve curvature adjustment can also be adopted.

[0038] The following describes in detail the splicable display device provided by the embodiment of the present application, taking a display module with a curved display as an example. Specifically, the splicable display device includes a fixed component arranged on the back of a back panel unit 12, and the fixed component includes an angle adjustment structure 2, and the angle adjustment structure 2 is used to adjust the angle of a display panel 11 of the display module 1 within a first plane, that is, to enable the display module 1 to rotate a certain angle around a rotation axis perpendicular to the first plane. The first plane is perpendicular to the display surface of the display module 1. Figure 1 As shown, the first plane is parallel to the plane where the X direction and the Z direction are located, and the display surface of the display module 1 is perpendicular to the plane where the X direction and the Z direction are located, that is, perpendicular to the above-mentioned first plane. When the splicable display device uses a hanging method to fix the display module 1, the above-mentioned first plane is parallel to the horizontal plane, and the display surface of the display module 1 is perpendicular to the horizontal plane. The mutual perpendicularity here is not an absolute 90 degrees, as long as the display module 1 is bent along the XZ plane shown in the figure.

[0039] The angle adjustment structure 2 can be of various types. For example, in this embodiment, Figure 1 and Figure 2As shown, the angle adjustment structure 2 includes a first fixing member 21 and a rotating member 24, wherein the first fixing member 21 is connected to the position adjustment structure (not shown in the figure). In this embodiment, the first fixing member 21 includes a strip-shaped vertical hanging plate, and the length direction of the strip-shaped vertical hanging plate is perpendicular to the first plane (i.e., parallel to the plane where the X direction and the Z direction are located). Since the strip-shaped vertical hanging plate is in the shape of a flat plate, even if the display module 1 is a curved display, a planar connection can also be achieved, thereby facilitating the installation of the display module 1 and improving the installation stability. In addition, it can also be applicable to display modules with flat or curved displays. Of course, in practical applications, other planar structures can also be used as connection structures for hanging the display module 1.

[0040] The rotating member 24 is connected to the first fixing member 21 and the display module 1 respectively, and the rotating member 24 is configured to enable the display module 1 to rotate relative to the first fixing member 21 around a rotation axis perpendicular to the first plane, that is, the rotation axis is parallel to the Y direction. With the help of the rotating member 24, the angle of the display surface of the display module 1 in the first plane can be adjusted. The structure of the rotating member 24 can be various, such as Figure 2 As shown, the rotating member 24 includes at least one first rotation damper, which is used to fix the display module 1 at any angle within the first plane. That is, when a torque is applied to the first rotation damper, the first fixing member 21 and the display module 1 produce relative rotation, and when the torque is released, the first fixing member 21 and the display module 1 remain stationary at the current angle.

[0041] There are many specific connection methods for the rotating member 24 to be connected to the first fixing member 21 and the display module 1, for example, Figure 1 As shown, first parallel connecting plates 22 are respectively arranged at both ends of the strip-shaped vertical hanging plate, and second parallel connecting plates 131 are arranged on the back side of the display module 1 (for example, the curvature adjusting device 13). The first parallel connecting plates 22 and the second parallel connecting plates 131 are arranged opposite to each other and are parallel to the first plane, that is, parallel to the planes where the X direction and the Z direction are located. In addition, the rotating member 24 ( Figure 1 ) is connected between the first parallel connection plate 22 and the second parallel connection plate 131. Figure 2 As shown, the first rotation damper includes a first adapter 241, a second adapter 243 and a rotation damping member 242 connected therebetween, wherein the first adapter 241 and the second adapter 243 are fixedly connected to the first parallel connecting plate 22 and the second parallel connecting plate 131 respectively, so that.

[0042] In some embodiments, in order to improve the structural stability, there may be multiple first fixing members 21, and the multiple first fixing members 21 are symmetrically distributed relative to the back side of the display module 1, for example Figure 1 There are two first fixing members 21. The number of rotating members 22 is the same as the number of first fixing members 21, and each rotating member 22 is connected to each first fixing member 21 in a one-to-one correspondence. Figure 1 Each first fixing member 21 is a strip-shaped vertical hanging plate, and correspondingly, the rotating member 22 includes two first rotation dampers, which are respectively arranged at two ends of the strip-shaped vertical hanging plate, and the rotation axes of the two first rotation dampers coincide with each other.

[0043] like Figure 3 , which is a rear view of the splicable display device (not installed with the bracket) provided in the embodiment of the present application. The splicable display device also includes a position adjustment structure 3, which is connected to the above-mentioned angle adjustment structure 2 and the bracket ( Figure 3 The position adjustment structure 3 is connected to the display module 1 in the first direction (i.e., X direction), the second direction (i.e., Z direction), and the third direction (i.e., Y direction), wherein any two of the first direction (i.e., X direction), the second direction (i.e., Z direction), and the third direction (i.e., Y direction) are perpendicular to each other, and the first direction (i.e., X direction) and the second direction (i.e., Z direction) are parallel to the first plane, and the third direction (i.e., Y direction) is perpendicular to the first plane. The position adjustment structure 3 is used to adjust the position of the display module 1 in the first direction, the second direction, and the third direction, which can not only make the stacked display modules more compact, but also improve the convenience and safety of stacking.

[0044] The position adjustment structure 3 may have various structures. For example, the position adjustment structure 3 includes a second fixing member and a position adjustment component. Figure 3 and Figure 4 As shown, the second fixing member, for example, includes a rectangular frame 32 and a fixing plate 31, wherein the fixing plate 31 is superimposed on the rectangular frame 32 and is located on a side close to the display module 1, and the fixing plate 31 is respectively connected to the rectangular frame 31 and the angle adjustment structure 2, and the fixing plate 31 is used to install the system box 4.

[0045] In some embodiments, in order to facilitate installation, the splicable display device provided in the embodiment of the present application further includes a parallel adjustment structure, which is connected between the angle adjustment structure 2 and the position adjustment structure 3, and is used to adjust the relative position between the angle adjustment structure 2 and the position adjustment structure 3 in the first direction (i.e., the X direction). For example, the parallel adjustment structure includes a strip hole 316 provided on the fixing plate 31 and an adjustment screw 23 provided on the first fixing member 21, wherein the length direction of the strip hole 316 is parallel to the above-mentioned first direction; the adjustment screw 23 can be fixed at different positions in the length direction of the strip hole 316, so that the relative position between the fixing plate 31 and the first fixing member 21 in the first direction (i.e., the X direction) can be adjusted.

[0046] like Figure 5 As shown, a first connecting member 34 is provided on the rectangular frame 32, and a second connecting member 5 is provided on the bracket. The first connecting member 34 is connected to the second connecting member 5 in a hanging manner, so as to realize the overall hanging of the rectangular frame 32 and the display module 1 connected thereto. Specifically, as Figure 4 As shown, four first connecting members 34 are respectively provided at the four corners of the rectangular frame 32, and four second connecting members 5 are correspondingly provided on the bracket (not shown in the figure), and each first connecting member 34 is connected to each second connecting member 5 in a one-to-one correspondence. By providing four first connecting members 34 at the four corners of the rectangular frame 32, the structural stability can be improved.

[0047] The position adjustment component is used to adjust the relative position of the first connecting member 34 and the second connecting member 5 in the first direction, the second direction and the third direction, so as to adjust the position of the display module 1 in the first direction, the second direction and the third direction, which can not only make the stacked display module more compact, but also improve the convenience and safety of stacking. Adapting to the above four first connecting members 34, there are four position adjustment components, and each position adjustment component is used to adjust the relative position of each first connecting member 34 and the corresponding second connecting member 5 in the first direction, the second direction and the third direction in a one-to-one correspondence.

[0048] The position adjustment component may have various structures. For example, the position adjustment component includes three adjustment screws, and the axes of the three adjustment screws are parallel to the first direction, the second direction and the third direction, respectively. Figure 5 As shown, an adjusting screw 342 whose axis is parallel to the first direction (i.e., the X direction) and an adjusting screw 341 whose axis is parallel to the second direction (i.e., the Z direction) are shown, and an adjusting screw whose axis is parallel to the third direction (i.e., the Y direction) is located at the bottom of the second connecting member 5 ( Figure 5 (not shown). In the second connecting member 5, at least one threaded hole is provided, and the threaded hole is parallel to the first direction (i.e., the X direction). The adjusting screw 342 cooperates with the threaded hole and can abut against the surface opposite to the first connecting member 34. Since the bracket and its second connecting member 5 are always fixed, the adjusting screw 342 can be rotated clockwise or counterclockwise to push the first connecting member 34 to move relative to the second connecting member 5 along the first direction. Figure 5 As shown, two threaded holes are respectively provided on both sides of the first connecting member 34, and an adjusting screw 342 is provided in each threaded hole so as to be able to move leftward or rightward in the first direction. Similarly, a threaded hole is provided in the first connecting member 34, and an adjusting screw 341 cooperates with the threaded hole and can abut against the surface opposite to the second connecting member 5.

[0049] It should be noted that, in actual applications, the first connecting member 34 and the second connecting member 5 can also adopt any other structure, and the connection method between the two may vary depending on the structure, and the adjusting screw may be threadedly connected to one of the first connecting member 34 and the second connecting member 5, and offset against the other of the first connecting member 34 and the second connecting member 5, as long as the relative position of the first connecting member 34 and the second connecting member 5 can be adjusted.

[0050] In some embodiments, Figure 4 As shown, first parallel flanges, i.e., two first parallel flanges (321, 324), are respectively provided at the upper and lower ends of the rectangular frame 32, and second parallel flanges, i.e., two second parallel flanges (311, 314), are respectively provided at the upper and lower ends of the fixing plate 31, and the first parallel flanges and the second parallel flanges are parallel to the first plane; wherein each first parallel flange is opposite to the corresponding second parallel flange, i.e., the first parallel flange 321 is opposite to the second parallel flange 311; the first parallel flange 324 is opposite to the second parallel flange 314, and a second rotation damper 33 is provided between each first parallel flange and the corresponding second parallel flange, for making the fixing member 31 rotate around a rotation axis perpendicular to the first plane, so that the angle of the fixing member 31 in the first plane can be fine-tuned, thereby providing convenience for installation.

[0051] In some embodiments, after fine-tuning the angle of the fixing member 31 in the first plane by using the above-mentioned second rotation damper 33, in order to lock the relative angle between the fixing member 31 and the rectangular frame 32, a first fastener 313 is provided on the second parallel flange 311 located at the upper end of the fixing plate 31, and a second fastener 325 is correspondingly provided on the first parallel flange 324 located at the lower end of the rectangular frame 32; and, a first arc-shaped hole 323 centered on the rotation axis of the above-mentioned second rotation damper 33 is provided on the first parallel flange 321 located at the upper end of the rectangular frame 31, and a second arc-shaped hole 315 centered on the rotation axis of the above-mentioned second rotation damper 33 is correspondingly provided on the second parallel flange 314 located at the lower end of the fixing plate 32; the first fastener 313 is fixedly connected to the first arc-shaped hole 323 at different positions, and the second fastener 325 is fixedly connected to the second arc-shaped hole 315 at different positions to lock the relative angle between the fixing member 31 and the rectangular frame 32. In addition, for the convenience of installation, the first fastener 313 and the second fastener 325 are both arranged on the outside of the corresponding flange.

[0052] In some embodiments, Figure 6As shown, in the display module 1, at least one side of the display panel is provided with a signal board 6, and the signal transmission line 7 of the display panel needs to be exposed to be connected to the signal board 6. In this case, optionally, an insulating shielding member 8 is covered on the overlapping area where the signal transmission line 7 is exposed to protect the signal transmission line 7. In this way, all sides of the display module 1 can be used for overlapping with other display modules.

[0053] In the prior art, Figure 7 and Figure 8 As shown, for a conventional display module, its thickness is relatively large (generally greater than 1 mm). If such a display module is stacked, there will be a relatively large picture gap in the display, such as Figure 7 As shown, when the four display modules L1, L2, R1 and R2 are stacked, R1 and L2 are stacked on the back side of L1, and R2 is stacked on the back side of L2. Assuming that the thickness of each display module 1 is D1, the stacking of the four display modules L1, L2, R1 and R2 will form a display drop of D2, which is equal to the sum of twice D1 and the assembly gap. The more modules are spliced, the more the drop will accumulate. Therefore, only display modules with smaller thickness can be used, such as OLED display modules (thickness less than 1mm), which are spliced ​​in a stacking manner to reduce the seams between display modules. For example, Figure 8 and Fig. 9 As shown, the frame parts of the two display modules are overlapped and shielded, and the overlapped part g2 is equal to the frame width of one display module. After overlapping, the gap between the two display modules is G2.

[0054] Moreover, if Fig. 9 As shown in the figure on the left, at least one side of the back panel unit 12 is located inside the side of the corresponding display panel 11, so as to form an overlapping area a at the edge of the back of the display panel 11, and the overlapping area a is used to overlap with the frame area of ​​the front of other display panels 11. As can be seen from the figure on the right, by setting the overlapping area a, the height difference effect between the stacked display modules can be ignored.

[0055] like Fig.10 The figure shows a rear view of two display modules provided in the embodiment of the present application after being stacked. The two display modules are fixed on two brackets 9 respectively, and the corresponding angles and positions are adjusted by using their respective splicable display devices to achieve stacking.

[0056] To sum up, the spliced ​​display device provided in the embodiment of the present application, by using the angle adjustment structure 2 to adjust the angle of the display surface of the display module 1 in the first plane, and using the position adjustment structure 3 to adjust the position of the display module 1 in the first direction, the second direction and the third direction, can not only make the stacked display modules more compact, but also improve the convenience and safety of stacking. In addition, the spliced ​​display device provided in the present embodiment is suitable for display modules of flat display and curved display.
