[0002] In the related art, display devices such as LED (Light Emitting Diode) all-in-one machines usually include multiple display screens, which are spliced ​​together and cooperate to display images, which makes the size of the display device usually large, which is not conducive to transportation and carrying. Therefore, when transporting the display device, the user needs to disassemble the multiple display screens and stack them on each other to facilitate transportation to the use scene. After arriving at the use scene, the user first takes out the multiple display screens, and then splices and assembles the multiple display screens to enable the display device to realize the display function. Therefore, the display device needs to be assembled before use, and the assembly steps are relatively cumbersome, which makes the assembly efficiency of the display device low and reduces the user experience.

[0044] The following is a detailed description with reference to the accompanying drawings and embodiments:

[0045] Please also read Figures 1 to 4 The display device includes a first display screen 10, a second display screen 20 and a rotating mechanism 30. The first display screen 10 has a first display surface 11, and the first display surface 11 is arranged on one side of the first display screen 10 along the thickness direction thereof. The second display screen 20 has a second display surface 21, and the second display surface 21 is arranged on one side of the second display screen 20 along the thickness direction thereof. The rotating mechanism 30 includes a first rotating arm 31 and a second rotating arm 32. The second rotating arm 32 is rotatably connected to the first rotating arm 31. Along the thickness direction of the first display screen 10, the first rotating arm 31 is connected to the side of the first display screen 10 that is away from the first display surface 11. Along the thickness direction of the second display screen 20, the second rotating arm 32 is connected to the side of the second display screen 20 that is away from the second display surface 21. The first rotating arm 31 can rotate relative to the second rotating arm 32 to drive the first display screen 10 and the second display screen 20 to unfold, or drive the first display screen 10 and the second display screen 20 to fold.

[0046] When the first display screen 10 and the second display screen 20 are unfolded, Figure 1 As shown, the first display surface 11 and the second display surface 21 are spliced ​​along a first direction Y1, wherein the first direction Y1 is parallel to the first display surface 11, and the first direction Y1 is also parallel to the second display surface 21. The first direction Y1 is perpendicular to the rotation axis of the first rotating arm 31.

[0047] When the first display screen 10 and the second display screen 20 are folded, Figure 3 and Figure 4As shown, the first display screen 10 and the second display screen 20 are distributed along the second direction X2. The second direction X2 intersects the first display surface 11 and the second display surface 21. The second direction X2 is perpendicular to the rotation axis of the first rotating arm 31.

[0048] The first direction Y1 is substantially parallel to the first display surface 11 and the second display surface 21, and is substantially perpendicular to the rotation axis of the first rotating arm 31, with a slight deviation allowed. The second direction X2 is substantially perpendicular to the rotation axis of the first rotating arm 31, with a slight deviation allowed.

[0049] The first display surface 11 is the screen surface of the first display screen 10 for displaying image and text information, and the second display surface 21 refers to the screen surface of the second display screen 20 for displaying image and text information. The first display surface 11 and the second display surface 21 can be spliced ​​with each other when in use to match the display screen.

[0050] Folding of the first display screen 10 and the second display screen 20 along the second direction X2 means that the projections of the first display screen 10 and the second display screen 20 along the second direction X2 at least partially overlap.

[0051] It can be understood that the display device has an unfolded state and a folded state. In the unfolded state, the first display screen 10 and the second display screen 20 are unfolded, and the first display surface 11 and the second display surface 21 are spliced ​​along the first direction Y1. In the folded state, the first display screen 10 and the second display screen 20 are folded, and the first display surface 11 and the second display surface 21 are distributed along the second direction X2.

[0052] It should be noted that the first direction Y1 and the second direction X2 are directions derived from the display device in different usage states.

[0053] Specifically, the first direction Y1 refers to the direction in which the first display surface 11 and the second display surface 21 are spliced ​​when the first display screen 10 and the second display screen 20 are unfolded. Figure 1 As shown, Figure 1 1 shows a spatial coordinate system 1, and directions X1, Y1, and Z1 are the directions of the three coordinate axes in the spatial coordinate system 1, that is, direction X1 is perpendicular to direction Y1, direction X1 is perpendicular to direction Z1, and direction Y1 is perpendicular to direction Z1. Figure 1 The direction Y1 shown in FIG. 1 is parallel to the first display surface 11 and the second display surface 21, and the rotation axis of the first rotating arm 31 is parallel to Figure 1 Direction Z1 indicated in FIG.

[0054] The second direction X2 refers to the approximate distribution direction of the first display screen 10 and the second display screen 20 when the first display screen 10 and the second display screen 20 are folded. Figure 4 As shown, Figure 4 The second spatial coordinate system is shown, and the directions X2, Y2, and Z1 are the directions of the three coordinate axes in the second spatial coordinate system, that is, the direction X2 is perpendicular to the direction Y2, the direction X2 is perpendicular to the direction Z2, and the direction Y2 is perpendicular to the direction Z2. Figure 4 The direction X2 shown in the figure intersects the first display surface 11 and the second display surface 21. The rotation axis of the first rotating arm 31 is parallel to Figure 4 The direction Z2 is shown in FIG.

[0055] The second direction X2 may be perpendicular to at least one of the first display surface 11 and the second display surface 21. As an example, Figure 4 As shown, the second direction X2 is perpendicular to the first display surface 11 and perpendicular to the second display surface 21 , based on which the first display surface 11 and the second display surface 21 are parallel to each other.

[0056] In the display device provided in the embodiment of the present application, when the user needs to watch the display device, the user can drive the first display screen 10 and the second display screen 20 to rotate by means of the first rotating arm 31 and the second rotating arm 32 of the rotating mechanism 30. The first display screen 10 and the second display screen 20 can be rotated to the unfolded state driven by the first rotating arm 31 and the second rotating arm 32, so that the first display surface 11 and the second display surface 21 are spliced ​​along the first direction Y1 to match the display screen. When the display device needs to be stored or transported, the user can drive the first display screen 10 and the second display screen 20 to rotate by means of the rotating mechanism 30, so that the first display screen 10 and the second display screen 20 are rotated to the folded state, so that the first display screen 10 and the second display screen 20 are distributed in sequence along the second direction X2, so as to facilitate the storage or carrying of the display device. In this way, when transporting the display device, the user can rotate the first display screen 10 and the second display screen 20 to a folded state that is easy to transport and carry, and then drive the rotating mechanism 30 to rotate to unfold the first display screen 10 and the second display screen 20 when watching the display device, eliminating the operation steps of disassembling the first display screen 10 and the second display screen 20 and then splicing them together, simplifying the assembly steps of the display device, improving the assembly efficiency of the display device, and thus optimizing the user experience.

[0057] In some embodiments, the first rotating arm 31 is provided with a rotating shaft, and the second rotating arm 32 is provided with a sleeve, and the rotating shaft is inserted into the sleeve, so that the second rotating arm 32 can directly rotate with the first rotating arm 31. Alternatively, a rotating shaft is provided between the first rotating arm 31 and the second rotating arm 32, and the first rotating arm 31 and the second rotating arm 32 are respectively rotatably connected to the rotating shaft to realize the rotational connection between the first rotating arm 31 and the second rotating arm 32. Among them, the rotational connection mode of the first rotating arm 31 and the second rotating arm 32 is not limited to the above two forms, and can also be other forms.

[0058] It should be supplemented here that the rotation axis of the first rotating arm 31 and the rotation axis of the second rotating arm 32 can be parallel to each other or overlap each other.

[0059] In addition, the first rotating arm 31 is connected to the side of the first display screen 10 facing away from the first display surface 11, and the second rotating arm 32 is connected to the side of the second display screen 20 facing away from the second display surface 21. The first rotating arm 31 and the second rotating arm 32 are not likely to cause obstacles to the splicing of the first display screen 10 and the second display screen 20 along the first direction Y1. At the same time, the user does not need to set a groove or the like between the first display screen 10 and the second display screen 20 for installing the first rotating arm 31 and the second rotating arm 32, so that the installation method of the first rotating arm 31 and the second rotating arm 32 is simpler and easier to process.

[0060] In some embodiments, the display device may include multiple display screens, and any two adjacent display screens may be defined as a first display screen 10 and a second display screen 20. Accordingly, the rotating mechanism 30 is provided in multiple numbers, and one rotating mechanism 30 is correspondingly installed on the adjacent first display screen 10 and the second display screen 20, the first rotating arm 31 is connected to the side of the first display screen 10 facing away from the first display surface 11, and the second rotating arm 32 is connected to the side of the second display screen 20 facing away from the second display surface 21, the first rotating arm 31 can drive the first display screen 10 to rotate, and the second rotating arm 32 can drive the second display screen 20 to rotate, so that each first display surface 11 is correspondingly spliced ​​to each second display surface 21.

[0061] In some embodiments, see Figure 1 and Figure 2 The first rotating arm 31 is configured to rotate relative to the second rotating arm 32 along a first rotating direction a to drive the first display screen 10 and the second display screen 20 to unfold. The second rotating arm 32 is configured to rotate relative to the first rotating arm 31 along a second rotating direction b to drive the first display screen 10 and the second display screen 20 to unfold. The first rotating direction a and the second rotating direction b are opposite.

[0062] Wherein, the first rotation direction a and the second rotation direction b are both unidirectional. As an example, Figure 1As shown, the first rotation direction a can be clockwise, and the second rotation direction b can be counterclockwise. Conversely, the first rotation direction a can be counterclockwise, and the second rotation direction b can be clockwise.

[0063] In some embodiments, see Figure 2 , when the first display screen 10 and the second display screen 20 are unfolded, as shown in Figure 2 As shown, the first rotating arm 31 is abutted against the second rotating arm 32 along the first rotating direction a.

[0064] It can be understood that, in the unfolded state, the second rotating arm 32 abuts against the first rotating arm 31 along the second rotating direction b.

[0065] It can also be understood that the side of the first rotating arm 31 facing the second rotating arm 32 along the first rotating direction a abuts against the side of the second rotating arm 32 facing the first rotating arm 31 along the second rotating direction b.

[0066] When the first display screen 10 and the second display screen 20 are unfolded, the first rotating arm 31 abuts against the second rotating arm 32 along the first rotating direction a, and the second rotating arm 32 abuts against the first rotating arm 31 along the second rotating direction b, so that the rotation stroke of the first rotating arm 31 along the first rotating direction a is limited, and the rotation stroke of the second rotating arm 32 along the second rotating direction b is also limited. Therefore, the display device can be switched to the unfolded state by rotating until the first rotating arm 31 abuts against the second rotating arm 32, thereby improving the convenience of adjusting the use state of the display device.

[0067] In some embodiments, see Figures 1 to 4 , the first display screen 10 is further provided with a first end surface 12. The second display screen 20 is further provided with a second end surface 22. In the first rotation direction a, a first side surface 311 is provided on a side of the first rotating arm 31 facing the second rotating arm 32. The first side surface 311 is arranged flush with the first end surface 12. In the second rotation direction b, a second side surface 321 is provided on a side of the second rotating arm 32 facing the first rotating arm 31. The second side surface 321 is arranged flush with the second end surface 22. When the first display screen 10 and the second display screen 20 are unfolded, the first end surface 12 abuts against the second end surface 22 along the first direction Y1, and the first side surface 311 abuts against the second side surface 321 along the first direction Y1.

[0068] In actual use, the first end surface 12 is one side of the first display screen 10 along the length direction, and the second end surface 22 is one side of the second display screen 20 along the length direction.

[0069] Wherein, the first rotation direction a and the second rotation direction b are both unidirectional. As an example, Figure 1As shown, the first rotation direction a can be clockwise, and the second rotation direction b can be counterclockwise. Conversely, the first rotation direction a can be counterclockwise, and the second rotation direction b can be clockwise.

[0070] When the first display screen 10 and the second display screen 20 are unfolded, the first direction Y1 is parallel to the tangent direction of the first rotation direction a, and is also parallel to the tangent direction of the second rotation direction b.

[0071] When the first display screen 10 and the second display screen 20 are unfolded, the first side surface 311 abuts against the second side surface 321, thereby limiting the rotational travel of the first rotating arm 31 along the first rotational direction a, and limiting the rotational travel of the second rotating arm 32 along the second rotational direction b. Therefore, the display device can be switched to the unfolded state by rotating until the first side surface 311 abuts against the second side surface 321, thereby improving the convenience of adjusting the use state of the display device.

[0072] It can be understood that in other embodiments, a protrusion is provided on one side of the first rotating arm 31 along the first rotating direction a, and a protrusion is provided on one side of the second rotating arm 32 along the second rotating direction b. When the first rotating arm 31 rotates along the first rotating direction a and the second rotating arm 32 rotates along the second rotating direction b, the two can approach each other, so that the protrusion on the first rotating arm 31 abuts against the protrusion on the second rotating arm 32, and the first rotating arm 31 is limited along the first rotating direction a, and the second rotating arm 32 is limited in rotation along the second rotating direction b. Alternatively, in some other embodiments, a protrusion is provided on one side of the first rotating arm 31 along the first rotating direction a, and a groove is provided on one side of the second rotating arm 32 along the second rotating direction b. When the first rotating arm 31 rotates along the first rotating direction a and the second rotating arm 32 rotates along the second rotating direction b, the two can approach each other, so that the protrusion on the first rotating arm 31 is inserted into the groove on the second rotating arm 32, and the first rotating arm 31 is limited in rotation along the first rotating direction a, and the second rotating arm 32 is limited in rotation along the second rotating direction b. The abutting manner of the first rotating arm 31 and the second rotating arm 32 is not limited to the manner involved in the above-mentioned embodiment, and may also be other forms, which are not limited here.

[0073] In some embodiments, see Figures 1 to 4 The first side surface 311 is perpendicular to the first display surface 11 , and the second side surface 321 is perpendicular to the second display surface 21 .

[0074] The first side surface 311 is a plane perpendicular to the first display surface 11, and the second side surface 321 is a plane perpendicular to the second display surface 21. When the first side surface 311 and the second side surface 321 are rotated to abut against each other, the first display surface 11 and the second display surface 21 form an angle of 180° and can be spliced ​​with each other along the first direction Y1, so that the first display screen 10 and the second display screen 20 are unfolded.

[0075] In this way, when the first display screen 10 and the second display screen 20 are unfolded, the first side surface 311 can better abut against the second side surface 321, thereby making the joint gap between the first display surface 11 and the second display surface 21 smaller, thereby achieving a better display effect of the display device.

[0076] In some embodiments, see Figure 4 The first rotating arm 31 is configured to be able to rotate relative to the second rotating arm 32 along the second rotating direction b to drive the first display screen 10 and the second display screen 20 to fold. The second rotating arm 32 is configured to be able to rotate relative to the first rotating arm 31 along the first rotating direction a to drive the first display screen 10 and the second display screen 20 to fold. The first rotating direction a and the second rotating direction b are opposite.

[0077] In some embodiments, see Figure 3 and Figure 4 When the first display screen 10 and the second display screen 20 are folded, the first rotating arm 31 abuts against the second rotating arm 32 along the second rotating direction b.

[0078] Wherein, the first rotation direction a and the second rotation direction b are both unidirectional. As an example, Figure 4 As shown, the second rotation direction b can be clockwise, and the first rotation direction a is counterclockwise. Conversely, the first rotation direction a can be clockwise, and the second rotation direction b is counterclockwise.

[0079] When the first display screen 10 and the second display screen 20 are folded, the second direction X2 is parallel to the tangent direction of the first rotation direction a and is also parallel to the tangent direction of the second rotation direction b.

[0080] It can be understood that, in the unfolded state, the second rotating arm 32 abuts against the first rotating arm 31 along the first rotating direction a.

[0081] It can also be understood that the side of the first rotating arm 31 facing the second rotating arm 32 along the second rotating direction b abuts against the side of the second rotating arm 32 facing the first rotating arm 31 along the first rotating direction a.

[0082] When the first display screen 10 and the second display screen 20 are folded, the first rotating arm 31 abuts against the second rotating arm 32 along the second rotating direction b, and the second rotating arm 32 abuts against the first rotating arm 31 along the first rotating direction a, so that the rotation stroke of the first rotating arm 31 along the second rotating direction b is limited, and the rotation stroke of the second rotating arm 32 along the first rotating direction a is also limited. Therefore, the display device can be switched to the folded state by rotating until the first rotating arm 31 abuts against the second rotating arm 32, thereby improving the convenience of adjusting the use state of the display device.

[0083] In some embodiments, see Figures 2 to 5 , along the thickness direction of the first display screen 10, the first rotating arm 31 has a third end surface 312, and the third end surface 312 is arranged at one end of the first rotating arm 31 away from the first display screen 10. Along the thickness direction of the second display screen 20, the second rotating arm 32 has a fourth end surface 322, and the fourth end surface 322 is arranged at one end of the second rotating arm 32 away from the second display screen 20. When the first display screen 10 and the second display screen 20 are folded, the third end surface 312 abuts against the fourth end surface 322 along the second direction X2.

[0084] The rotational travel of the first rotating arm 31 and the second rotating arm 32 during the folding process can be limited by the third end face 312 of the first rotating arm 31 abutting against the fourth end face 322 of the second rotating arm 32. There is no need to set an additional limiting structure on the first rotating arm 31 and the second rotating arm 32, which saves processing steps and reduces processing costs.

[0085] In some embodiments, see Figure 4 The third end surface 312 is perpendicular to the thickness direction of the first display screen 10 . The fourth end surface 322 is perpendicular to the thickness direction of the second display screen 20 .

[0086] When the third end surface 312 and the fourth end surface 322 are rotated to be parallel to each other and abut against each other along the second direction X2, the thickness direction of the first display screen 10 and the thickness direction of the second display screen 20 are parallel to each other, and the first display surface 11 and the second display surface 21 are parallel to each other, so that the first display screen 10 and the second display screen 20 are folded along the second direction X2.

[0087] In this way, when the first display screen 10 and the second display screen 20 are folded, the first display screen 10 and the second display screen 20 are parallel to each other and have a certain distance therebetween, so that the first display screen 10 and the second display screen 20 are easier to place in a storage structure such as a box, thereby improving the storage convenience of the first display screen 10 and the second display screen 20.

[0088] In some embodiments, see Figure 4 and Figure 5The rotating mechanism 30 further includes a hinge structure 33. The first rotating arm 31 and the second rotating arm 32 are respectively connected to opposite ends of the hinge structure 33. The first rotating arm 31 and the second rotating arm 32 are rotatably connected through the hinge structure 33.

[0089] Specifically, the hinge structure 33 includes a first hinge end 331 and a second hinge end 332, and the first hinge end 331 and the second hinge end 332 can rotate relative to each other. The first rotating arm 31 and the second rotating arm 32 are respectively connected to the first hinge end 331 and the second hinge end 332 of the hinge structure 33 to realize the mutual rotation between the first rotating arm 31 and the second rotating arm 32.

[0090] In this way, the first rotating arm 31 and the second rotating arm 32 are connected by the hinge structure 33, so that the relative rotation range of the first rotating arm 31 and the second rotating arm 32 is larger, which is conducive to driving the first display screen 10 and the second display screen 20 to be better unfolded and folded.

[0091] In some embodiments, see Figure 5 The rotating mechanism 30 is provided with a first axis L. The rotating mechanism 30 is arranged axially symmetrically with respect to the first axis L.

[0092] Specifically, the first rotating arm 31 and the second rotating arm 32 are axially symmetrically arranged with respect to the first axis L, so that the dimension of the first rotating arm 31 along the thickness direction of the first display screen 10 when connected to the first display screen 10 is substantially the same as the dimension of the second rotating arm 32 along the thickness direction of the second display screen 20 when connected to the second display screen 20. In this way, the first display screen 10 and the second display screen 20 are not prone to step differences along the thickness direction.

[0093] In some embodiments, Figure 5 As shown, the first axis L, the rotation axis of the first rotating arm 31 and the rotation axis of the second rotating arm 32 are arranged to coincide with each other.

[0094] Alternatively, in other embodiments, the rotation axis of the first rotating arm 31 and the rotation axis of the second rotating arm 32 are parallel to each other, and the rotation axis of the first rotating arm 31 and the rotation axis of the second rotating arm 32 are both parallel to the first axis L. The rotation axis of the first rotating arm 31 and the rotation axis of the second rotating arm 32 are axially symmetrical with respect to the first axis L.

[0095] The first axis L is as follows: Figure 5 The axis L is shown in FIG.

[0096] In this way, after the first rotating arm 31 installed on the first display screen 10 and the second rotating arm 32 installed on the second display screen 20 drive the first display screen 10 and the second display screen 20 to rotate and splice, the first display screen 10 and the second display screen 20 are not prone to step differences along the thickness direction, so that the splicing effect of the first display screen 10 and the second display screen 20 is better, and the flatness of the surface used for display of the display device is improved.

[0097] In one embodiment, see Figures 1 to 5 At least one of the first rotating arm 31 and the second rotating arm 32 is provided with a positioning piece, and the other is provided with a positioning hole. When the first display screen 10 and the second display screen 20 are unfolded, the positioning piece and the positioning hole are plugged and matched along the first direction Y1.

[0098] The positioning piece can be a columnar structure, a strip structure, etc.

[0099] As an example, the first rotating arm 31 is provided with a first positioning member 315 and a second positioning hole 326, and the second rotating arm 32 is provided with a second positioning member 325 and a second positioning hole 326. When the first display screen 10 and the second display screen 20 are unfolded, the first positioning member 315 is inserted into the first positioning hole 316, and the second positioning member 325 is inserted into the second positioning hole 326.

[0100] Through the cooperation of the positioning piece and the positioning hole, the first rotating arm 31 is better aligned with the second rotating arm 32, reducing the shaking of the first rotating arm 31 and the second rotating arm 32 along the direction intersecting the first direction Y1, thereby improving the stability of the first display screen 10 and the second display screen 20 in the unfolded state.

[0101] In some embodiments, when the first display screen 10 and the second display screen 20 are unfolded, the first end surface 12 of the first display screen 10 abuts against the second end surface 22 of the second display screen 20 along the first direction Y1, and the first side surface 311 of the first rotating arm 31 abuts against the second side surface 321 of the second rotating arm 32 along the first direction Y1. In this way, the positioning member can make the side of the first rotating arm 31 used for connecting to the first display screen 10 better aligned with the side of the second rotating arm 32 used for connecting to the second display screen 20 along the thickness direction of the first display screen 10, thereby making the first display screen 10 and the second display screen 20 flush with each other along the thickness direction in the unfolded state, thereby improving the flatness of the display surface of the display device.

[0102] Alternatively, in one embodiment, the display device further comprises a fastener 40, and when the first display screen 10 and the second display screen 20 are unfolded, the fastener 40 fixes the first rotating arm 31 to the second rotating arm 32;

[0103] The fastener 40 may be a bolt, a captive screw, or the like.

[0104] When in use, the user drives the first rotating arm 31 and the second rotating arm 32 to rotate into place, the first display screen 10 and the second display screen 20 are unfolded, and then the fastener 40 is passed through the first rotating arm 31 and the second rotating arm 32 in sequence to fix the first display screen 10 and the second display screen 20 in the unfolded state.

[0105] In this way, the first display screen 10 and the second display screen 20 can be better fixed in the unfolded state, thereby improving the use stability of the display device in the unfolded state.

[0106] When the first display screen 10 and the second display screen 20 are unfolded, the first end surface 12 of the first display screen 10 abuts against the second end surface 22 of the second display screen 20 along the first direction Y1, and the first side surface 311 of the first rotating arm 31 abuts against the second side surface 321 of the second rotating arm 32 along the first direction Y1. In this way, the fastener 40 can improve the connection strength between the first side surface 311 and the second side surface 321, reduce the connection gap between the first side surface 311 and the second side surface 321, and further reduce the splicing gap between the first end surface 12 and the second end surface 22, thereby reducing the splicing gap between the first display surface 11 and the second display surface 21, and improving the display effect of the display device.

[0107] Alternatively, in one embodiment, the first rotating arm 31 is provided with a first magnetic member 313. The second rotating arm 32 is provided with a second magnetic member 323. When the first display screen 10 and the second display screen 20 are unfolded, the first magnetic member 313 is attracted to the second magnetic member 323.

[0108] The first magnetic member 313 and the second magnetic member 323 may be magnets having magnetic properties.

[0109] The first magnetic member 313 is magnetically attached to the second magnetic member 323, which increases the driving feel when the user adjusts the first rotating arm 31 or the second rotating arm 32. At the same time, the first magnetic member 313 and the second magnetic member 323 are magnetically matched, so that the first rotating arm 31 and the second rotating arm 32 are not easily separated from each other, and the splicing gap when the first display surface 11 and the second display surface 21 are spliced ​​is reduced.

[0110] Alternatively, in one embodiment, the first rotating arm 31 is provided with a first clamping member 314, and the second rotating arm 32 is provided with a second clamping member 324. When the first display screen 10 and the second display screen 20 are unfolded, the first clamping member 314 is clamped to the second clamping member 324.

[0111] The first clamping member 314 may be an eccentric hook, and the second clamping member 324 may be a pin seat that cooperates with the eccentric hook. When the first display screen 10 and the second display screen 20 are unfolded, the eccentric hook can be driven by an external force to rotate and hook onto the pin seat, so that the first rotating arm 31 and the second rotating arm 32 are connected.

[0112] When the first display screen 10 and the second display screen 20 are unfolded, the first rotating arm 31 and the second rotating arm 32 are engaged with each other and are not easily disengaged, so that the connection strength of the first display screen 10 and the second display screen 20 is higher when they are spliced.

[0113] It can be understood that the first rotating arm 31 and the second rotating arm 32 of the display device have at least one structure in the above embodiments.

[0114] The above are only preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
