It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.

Fig. 1 is a schematic front oblique view of a display device according to an embodiment of the present invention, fig. 2 is a schematic back oblique view of the display device shown in fig. 1, fig. 3 is a schematic front oblique view disassembled view of the display device shown in fig. 1, fig. 4 is an exploded schematic view of the display device shown in fig. 1, fig. 5 is a schematic back view of the display device shown in fig. 1, fig. 6 is a schematic side view of the display device shown in fig. 1, and fig. 7 is a schematic front view of the display device shown in fig. 1, referring to fig. 1 to 7, the display device includes a plurality of display screen units 1 and a plurality of support units 2. The display unit 1 is used for displaying an image, and the display unit 1 may include, for example, an organic light emitting display panel, a liquid crystal display panel, a quantum dot display panel, a micro light emitting diode display panel, or the like. The support unit 2 is for supporting the display screen unit 1. Wherein the support unit 2 includes a support portion 21, and the support portion 21 includes a first support portion 211 and a second support portion 212. The first support portion 211 extends in a first direction X, and the second support portion 212 extends in a second direction Y. The first direction X intersects the second direction Y. In one embodiment, the first direction X and the second direction Y may be perpendicular to each other. In another embodiment, the first direction X and the second direction Y may not be perpendicular and form an included angle greater than 0 ° and less than 90 °.

Fig. 8 is a schematic view of the display device shown in fig. 1 after two supporting units connected along a first direction rotate with a second direction as a rotating shaft direction, and referring to fig. 1-8, two supporting units 2 connected along the first direction X can rotate relatively with the second direction Y as the rotating shaft direction. Fig. 9 is a schematic view of two supporting units connected in a second direction in the display device shown in fig. 1 after rotating with the first direction as a rotating shaft direction, and referring to fig. 9, two supporting units 2 connected in the second direction Y can rotate relatively with the first direction X as the rotating shaft direction. It should be noted that, because the two support units 2 connected along the first direction X can rotate relatively, after rotating with the second direction Y as the rotating shaft direction, the extending direction of the first support portion 211 originally extending along the first direction X can be changed, in each embodiment of the present invention, the first support portion 211 extending along the first direction X means that when each display screen unit 1 is located on the same plane, the first support portion 211 extends along the first direction X. Similarly, since the two support units 2 connected along the second direction Y can rotate relatively, after rotating with the first direction X as the rotating shaft direction, the extending direction of the second support portion 212 originally extending along the second direction Y can be changed, in each embodiment of the present invention, the second support portion 212 along the second direction Y means that when the display screen units 1 are located on the same plane, the second support portion 212 along the second direction Y.

The embodiment of the invention provides a display device which comprises a plurality of display screen units 1 and a plurality of supporting units 2. One supporting unit 2 supports one display screen unit 1, or one supporting unit 2 supports a plurality of display screen units 1. The support portion 21 includes a first support portion 211 and a second support portion 212. The first supporting portions 211 of two adjacent supporting units 2 are connected in the first direction X. After the two support units 2 rotate by taking the second direction Y as the rotating shaft direction, the extending direction of the first support part 211 of at least one support unit 2 can be no longer along the first direction X, and the extending directions of the first support parts 211 of two adjacent support units 2 are crossed, so that the display angle of each display screen unit 1 can be adjusted by the display device in the X direction. The second support portions 212 of two adjacent support units 2 are connected in the second direction Y. After the two support units 2 rotate with the first direction X as the rotating shaft direction, the extending direction of the second support portion 212 of at least one support unit 2 is no longer along the second direction Y, and the extending directions of the second support portions 212 of two adjacent support units 2 are crossed, so that the display angle of each display screen unit 1 can be adjusted by the display device in the Y direction. In summary, the display device provided by the embodiment of the invention can adjust the display angle of each display screen unit 1 in two mutually intersecting directions.

Alternatively, referring to fig. 1 to 7, the display device further includes a connector 3, and the connector 3 includes a first connector 31 and a second connector 32. With respect to the two support units 2 connected in the first direction X, the first support portion 211 of one of the support units 2 is connected to the first support portion 211 of the other support unit 2 by the first connecting member 31. Along the first direction X, the first supporting portions 211 of two adjacent supporting units 2 are connected by the first connecting member 31. At least one support unit 2 is rotatable relative to the first connection member 31. In one embodiment, the two support units 2 connected to the first connecting member 31 are both rotatably connected to the first connecting member 31, and the two support units 2 connected to the first connecting member 31 are both rotatable relative to the first connecting member 31. In another embodiment, one of the two support units 2 connected to the first connecting member 31 is rotatably connected to the first connecting member 31, the other of the two support units 2 connected to the first connecting member 31 is fixedly connected to the first connecting member 31, and the support unit 2 is fixed to the first connecting member 31 and cannot rotate relatively. For two support units 2 connected in the second direction Y, the second support portion 212 of one support unit 2 is connected to the second support portion 212 of the other support unit 2 by the second connector 32. The second support parts 212 of two adjacent support units 2 are connected by the second connector 32 along the second direction Y. At least one support unit 2 is rotatable relative to the second link 32. In one embodiment, the two support units 2 connected to the second link 32 are both rotatably connected to the second link 32, and the two support units 2 connected to the second link 32 are both rotatable relative to the second link 32. In another embodiment, one of the two support units 2 connected to the second link 32 is rotatably connected to the second link 32, and the other of the two support units 2 connected to the second link 32 is fixedly connected to the second link 32, and the support unit 2 is fixed to the second link 32 and cannot rotate relative thereto.

Alternatively, referring to fig. 4, the connector 3 includes a positioning hole 33. The supporting unit 2 further includes a first positioning post 24, and the first positioning post 24 is sleeved in the positioning hole 33. In the embodiment of the present invention, the first positioning column 24 is sleeved in the positioning hole 33, and the positioning hole 33 is sleeved on the outer surface of the first positioning column 24, so that the relative rotation between the connecting member 3 and the supporting unit 2 is realized by the rotation of the first positioning column 24 in the positioning hole 33. The position of the positioning hole 33 defines the position of the rotation axis. If the positioning hole 33 extends along the first direction X, the first direction X is a rotation axis direction. If the positioning hole 33 extends along the second direction Y, the second direction Y is the rotation axis direction.

Exemplarily, referring to fig. 4, the positioning hole 33 is a through hole, that is, the positioning hole 33 is a hole penetrating through a sidewall of the connector 3. In other embodiments, the positioning hole 33 may also be a blind hole, i.e. the positioning hole 33 is a hole that does not penetrate through the side wall of the connector 3.

Alternatively, referring to fig. 4, the connecting member 3 includes a first sidewall 301, a second sidewall 302, and a third sidewall 303 connected in sequence, the first sidewall 301 being opposite to the third sidewall 303. The first sidewall 301 and the third sidewall 303 are connected by a second sidewall 302. No side wall connecting the first side wall 301 and the third side wall 303 is provided opposite the second side wall 302. The first, second and third sidewalls 301, 302 and 303 are connected in a C-shape. The opening of the connecting member 3 faces in a direction away from the display screen unit 1 toward the second side wall 302. The positioning holes 33 are provided in the first sidewall 301 and the third sidewall 303. In the embodiment of the present invention, the first sidewall 301, the second sidewall 302 and the third sidewall 303 form a C-shaped opening, and the opening of the connecting member 3 faces the direction of the second sidewall 302 away from the display screen unit 1. When the supporting unit 2 and the connecting member 3 rotate relatively, the supporting unit 2 can rotate around the first positioning column 24 in a direction away from the display screen unit 1, that is, the supporting unit 2 can rotate around the positioning hole 33 in a direction away from the display screen unit 1. The opening of the connecting piece 3 not only defines the direction of rotation of the support unit 2 about the first positioning column 24, but also defines the angular range over which the support unit 2 can be rotated relative to the connecting piece 3.

Optionally, with reference to fig. 1-7, support unit 2 further comprises extension 22, extension 22 comprising first extension 221 and second extension 222. The first extending portion 221 is slidably connected to the first supporting portion 211 and can slide relatively along the first direction X. Since the two support units 2 connected along the first direction X can rotate relatively, after rotating with the second direction Y as the rotating shaft direction, the extending direction of the first support portion 211 originally extending along the first direction X can change, but no matter how the extending direction of the first support portion 211 changes, the first extending portion 221 and the first support portion 211 slide relatively along the extending direction of the first support portion 211. The second extending portion 222 is slidably connected to the second supporting portion 212 and can slide relatively along the second direction Y. Since the two support units 2 connected along the second direction Y can rotate relatively, after rotating with the first direction X as the rotating shaft direction, the extending direction originally extending the second support portion 212 along the second direction Y can change, but no matter how the extending direction of the second support portion 212 changes, the second extending portion 222 and the second support portion 212 both slide relatively along the extending direction of the second support portion 212. In the embodiment of the present invention, the supporting unit 2 further includes an extending portion 22, the extending portion 22 includes a first extending portion 221 and a second extending portion 222, and the first extending portion 221 and the first supporting portion 211 slide relatively along the extending direction of the first supporting portion 211, so that the first extending portion 221 can extend the length of the first supporting portion 211 along the extending direction thereof. The second extending portion 222 and the second supporting portion 212 slide relatively along the extending direction of the second supporting portion 212, so that the second extending portion 222 can extend the length of the second supporting portion 212 along the extending direction thereof. The use of the extension may include: first, in the process of assembling the adjacent supporting units 2 together, the distance between the adjacent two display screen units 1 may be greater than zero, thereby facilitating the assembly of the supporting units 2. After the assembly of the supporting unit 2 is completed, the distance between the adjacent display screen units 1 may be adjusted by the extension portion 22 so that the distance between the adjacent display screen units 1 is zero; secondly, the extension part 22 can also be used for adjusting the distance between two adjacent display screen units 1 so as to realize different placing position relations of the display screens; thirdly, after adjacent display screen units rotate relatively, the splicing positions of the display screens with the included angle position relation can be realized by adjusting the relative position relation between the extending parts and the supporting units.

Alternatively, referring to fig. 1-7, the extension 22 is sleeved with the support 21. The support portion 21 can be inserted into the extension portion 22 and can slide relative to the extension portion 22 along the extension direction of the support portion 21, so as to change the arm length. Alternatively, in another embodiment, the extension 22 may be inserted into the support 21. In the embodiment of the present invention, the first extending portion 221 is sleeved with the first supporting portion 211, and the first extending portion 221 and the first supporting portion 211 slide relatively along the extending direction of the first supporting portion 211, so that the first extending portion 221 can extend the length of the first supporting portion 211 along the extending direction thereof. The second extending portion 222 is sleeved with the second supporting portion 212, and the second extending portion 222 and the second supporting portion 212 slide relatively along the extending direction of the second supporting portion 212, so that the length of the second supporting portion 212 along the extending direction can be extended by the second extending portion 222.

The first support rod 213 of the second support portion 212 is inserted into the inner cavity of the second extension portion 222, and the second positioning post 214 of the second support portion 212 is inserted into the elongated hole 223 of the second extension portion 222. When the second extending portion 222 slides relative to the second supporting portion 212, the second positioning post 214 of the second supporting portion 212 moves in the elongated hole 223 of the second extending portion 222. In the embodiment of the present invention, the elongated hole 223 on the second extending portion 222 provides a moving space for the second positioning pillar 214 of the supporting portion 21, and the second positioning pillar 214 of the supporting portion 21 can move in the elongated hole 223 on the second extending portion 222 along the extending direction of the elongated hole 223, so as to define the sliding direction of the extending portion 22 relative to the supporting portion 21.
