Description

Display module, splicing screen and method for adjusting splicing seam thereof Technical Field

[0001] The present disclosure relates to the field of display technology, and in particular to a display module, a spliced ​​screen, and a method for adjusting a splicing seam thereof. Background Art

[0002] Spliced ​​display products are widely used outdoors because they form a larger screen by splicing multiple display modules together.

[0003] However, splicing often creates seams at the joints of display products, which can affect visual quality. When installing spliced ​​display products, installers are often required to manually adjust the seams to minimize their impact on the display. However, in outdoor environments, due to factors such as light, display module size, and weight, adjusting the seams to minimize their impact on the display is difficult and inefficient.

[0004] In view of this, how to conveniently and efficiently adjust the splicing seams of spliced ​​display products has become a technical problem that needs to be solved urgently.

[0083] The embodiments of the present disclosure provide a display module, a spliced ​​screen, and a method for adjusting the splicing seam thereof, to solve the above-mentioned problems existing in the prior art.

[0084] In order to make the above-mentioned purposes, features and advantages of the present disclosure more obvious and easy to understand, the present disclosure will be further described below with reference to the accompanying drawings and examples. However, the example embodiments can be implemented in various forms and should not be understood as being limited to the embodiments set forth herein; on the contrary, these embodiments are provided to make the present disclosure more comprehensive and complete, and to fully convey the concepts of the example embodiments to those skilled in the art. The same figure marks in the figures represent the same or similar structures, and their repeated descriptions will be omitted. The words expressing position and direction described in the present disclosure are all explained using the accompanying drawings as examples, but changes can be made as needed, and all changes are included in the scope of protection of the present disclosure. The drawings of the present disclosure are only used to illustrate relative position relationships and do not represent true proportions.

[0085] It should be noted that specific details are set forth in the following description to facilitate a full understanding of the present disclosure. However, the present disclosure can be implemented in a variety of ways different from those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present disclosure. Therefore, the present disclosure is not limited to the specific embodiments disclosed below. The subsequent description of the specification is a preferred embodiment of the present disclosure, but the description is for the purpose of illustrating the general principles of the present disclosure and is not intended to limit the scope of the present disclosure. The scope of protection of the present disclosure shall be as defined by the appended claims.

[0086] A display module, a spliced ​​screen, and a method for adjusting the splicing seam thereof provided by an embodiment of the present disclosure will be described in detail below with reference to the accompanying drawings.

[0087] 1 and 2 are three-dimensional schematic diagrams of a display module provided in an embodiment of the present disclosure. The display module includes:

[0088] Display panel 1; the display panel 1 can be an LED display panel, a MicroLED display panel, a liquid crystal display panel, an OLED display panel, etc.

[0089] The adjustment plate 3 has at least one first through hole H1 and a plurality of first holes H2 surrounding the first through hole H1; each first hole H2 surrounding the first through hole H1 is located at a different position of the first through hole H1. FIG3 is a top view of an adjustment plate provided in an embodiment of the present disclosure. The adjustment plate 3 in FIG3 has one first through hole H1 and four first holes H2 located at four positions above, below, left and right of the first through hole H1. The centers of the four first holes H2 are connected in sequence to form a square, and the first through hole H1 is located at the center of the square. FIG4 is a top view of another adjustment plate provided in an embodiment of the present disclosure. The adjustment plate 3 has one first through hole H1 and eight first holes H2 located at eight positions above, below, left, right, upper left, upper right, lower left and lower right of the first through hole H1. The centers of the eight first holes H2 are located on the same circle. If the first through hole H1 is circular, the circles formed by the centers of the first through hole H1 and the eight first holes H2 are concentric circles. Of course, only two first holes H2 can be provided as needed, such as only the first holes H2 at the upper and lower positions or the left and right positions in FIG3 . The number of first holes H2 on the specific adjustment plate 3 is not limited. The first holes H2 can be blind holes or through holes.

[0090] At least one telescopic rod 4 is provided, and the first end 4a of each telescopic rod 4 is fixedly connected to the display panel 1 through a first through hole H1. As shown in FIG1 , a connecting structure (not shown in FIG1 ) can be provided on the back of the display panel 1 to be directly fixedly connected to the first end 4a of the telescopic rod 4. Alternatively, as shown in FIG2 , a bracket 2 can be provided on the back of the display panel to fix the display panel 1 to the bracket 2, and the first end 4a of the telescopic rod 4 is fixedly connected to the bracket 2 through the first through hole H1 of the adjustment plate 3. In this way, the display panel 1 can be indirectly fixedly connected to the telescopic rod 4 via the bracket 2. The bracket 2 can be made of aluminum or other materials, without limitation.

[0091] The second end 4b of at least one telescopic rod 4 is inserted into any of the first holes H2, causing the center of the adjustment plate 3 to shift in the extension direction of the telescopic rod 4. The center-to-center distance d1 between the first through-hole H1 and the first hole H2 is either less than or greater than the length L of the telescopic rod 4 in its free state. Thus, when adjusting the seam between adjacent display modules, the insertion of the second end 4b of the telescopic rod 4 into one of the first holes H2 causes the adjustment plate 3 to shift toward or away from the first hole H2 where the second end 4b is inserted (at this point, the adjustment plate 3 can be considered to be in a shifted state).

[0092] In some embodiments, the telescopic rod 4 can utilize spring force, magnetic force, or electromagnetic force to adjust the insertion position of the second end 4b of the telescopic rod 4 .

[0093] Please refer to FIG. 5, which is a schematic diagram of the states of a telescopic rod provided by an embodiment of the present disclosure. The telescopic rod 4 includes a free state, a compressed state, and a stretched state. However, in the embodiment provided by the present disclosure, the telescopic rod 4 is only allowed to include two states. For example, when d1 < L, the telescopic rod 4 includes a free state and a compressed state. When d1 > L, the telescopic rod 4 includes a free state and a stretched state. When the second end 4b of the telescopic rod 4 is disposed outside the first hole H2, the telescopic rod 4 is in the free state. When d1 < L, when a compressive force for compressing the telescopic rod 4 is applied to the telescopic rod 4, and the second end 4b of the telescopic rod 4 is inserted into any one of the first holes H2, the telescopic rod 4 is in the compressed state. The second end 4b of the telescopic rod 4 generates a pushing force acting on the adjustment plate 3, causing the adjustment plate 3 to shift in the direction of the first hole H2 into which the second end 4b of the telescopic rod 4 is inserted. The adjustment plate 3 is in the offset state in the corresponding direction. When the adjustment plate 3 is fixed, the first end 4a of the telescopic rod 4 fixed to the display panel 1 pushes (the bracket 2 drives) the display panel 1 to shift in the direction of the compressive force of the telescopic rod 4, thereby reducing the size of the splicing seam between the adjustment plate 3 and the adjacent display module. When d1 < L, the smaller d1 is, the greater the corresponding compressive force is, and thus the greater the force for pushing the display module to move is.

[0094] Similarly, when d1 > L, when a pulling force for stretching the telescopic rod 4 is applied to the telescopic rod 4, and the second end 4b of the telescopic rod 4 is inserted into any one of the first holes H2, the telescopic rod 4 is in the stretched state. The second end 4b of the telescopic rod 4 generates a pulling force acting on the adjustment plate 3, causing the adjustment plate 3 to shift in the opposite direction of the first hole H2 into which the second end 4b of the telescopic rod 4 is inserted. The adjustment plate 3 is in the offset state in the corresponding opposite direction. When the adjustment plate 3 is fixed, the first end 4a of the telescopic rod 4 fixed to the display panel 1 pushes (the bracket 2 drives) the display panel 1 to shift in the direction of the pulling force of the telescopic rod 4, thereby reducing the size of the splicing seam between the adjustment plate 3 and the adjacent display module. When d1 > L, the greater d1 is, the greater the corresponding pulling force is, and thus the greater the force for pushing the display module to move is. <{

[0095] If the center distance d1 between the first through hole H1 and the first hole H2 is less than the length L of the telescopic rod 4 in the free state, after the second end 4b is inserted into a certain first hole H2, if the position of the display panel 1 is fixed, it will cause the adjustment plate 3 to shift in the direction of the first hole H2 into which the second end 4b is inserted. If the position of the adjustment plate 3 is fixed, the first end 4a of the telescopic rod 4 will push (the bracket 2 drives) the display panel to shift in the opposite direction of the first hole H2 into which the second end 4b is inserted.

[0096] If the center distance d1 between the first through hole H1 and the first hole H2 is greater than the length L of the telescopic rod 4 in the free state, after the second end 4b is inserted into a certain first hole H2, if the position of the display panel 1 is fixed, it will cause the adjustment plate 3 to shift in the opposite direction of the orientation of the first hole H2 into which the second end 4b is inserted. If the position of the adjustment plate 3 is fixed, the first end 4a of the telescopic rod 4 will push (the bracket 2带动) the display panel 1 to shift in the orientation of the first hole H2 into which the second end 4b is inserted.

[0097] It should be understood that before the display module is installed in the splicing screen, since the weight of the display panel 1 (and the bracket 2) is greater than that of the adjustment plate 3, at this time, the position of the display panel 1 can be regarded as fixed; after the display module is installed in the splicing screen, since the adjustment plate 3 needs to be fixed to the fixed frame in the display module, at this time, the position of the adjustment plate 3 can be regarded as fixed.

[0098] In some embodiments, the diameter D1 of the first hole H2 is substantially the same as the diameter D2 of the second end 4b.

[0099] As shown in FIGS. 1-3, in an ideal state, the diameter D1 of the first hole H2 is the same as the diameter D2 of the second end 4b. However, due to process errors, the diameters of the first hole H2 and the second end 4b are usually not exactly the same. In the embodiments provided in the present disclosure, when the second end 4b can just be inserted into the first hole H2, it can be regarded that the diameter D1 of the first hole H2 is substantially the same as the diameter D2 of the second end 4b (for example, 0<D2-D1≤0.1mm can be considered substantially the same). This can prevent the adjustment plate 3 from shaking in the plane where the adjustment plate 3 is located in the offset state, thereby improving the stability of the display module after adjusting the size of the splicing seam.

[0100] In the embodiments provided in the present disclosure, by providing at least one first through hole H1 and a plurality of first holes H2 surrounding the first through hole H1 in the display module, and a telescopic rod 4 fixedly connected to the display panel 1 through the first through hole H1, making the center distance d1 between the first through hole H1 and the first hole H2 less than or greater than the length of the telescopic rod in the free state, and making the second end 4b of at least one telescopic rod 4 for inserting into any first hole H2, so that the center of the adjustment plate 3 shifts in the extending direction of the telescopic rod 4. This facilitates adjusting the splicing seam with an adjacent display module. By inserting the second end 4b of the telescopic rod 4 into the required first hole H2, the adjustment plate 3 can be shifted in the orientation or the opposite orientation of the first hole H2 into which the second end 4b is inserted, thereby reducing the size of the splicing seam between the adjacent display modules, and further enabling convenient and efficient adjustment of the size of the splicing seam between two adjacent display modules and reducing the difficulty of adjusting the splicing seam.

[0101] As shown in FIGS. 1 and 2, the display module has a telescopic rod 4;

[0102] As shown in FIG. 3 and FIG. 4 , the adjustment plate 3 has a first through hole H1 , and the first through hole H1 is located at the center of the adjustment plate 3 .

[0103] In the embodiment provided by the present disclosure, by providing a telescopic rod 4 in the display module, the weight and manufacturing cost of the display module can be reduced. Accordingly, a first through hole H1 located in the center of the adjustment plate 3 is provided in the adjustment plate 3, which can prevent the adjustment plate 3 from being significantly biased toward the direction of the center of gravity due to the offset of the center of gravity, thereby effectively improving the accuracy of the splicing seam adjustment.

[0104] Please refer to FIG6 , which is a three-dimensional schematic diagram of another display module provided by an embodiment of the present disclosure. The display module has an even number of telescopic rods 4 ;

[0105] The adjustment plate 3 has an even number of first through holes H1 symmetrically arranged about the center of the adjustment plate 3 .

[0106] As shown in Figure 6, a display module can have two telescopic rods 4, and the corresponding adjustment plate 3 has two first through holes H1, and the two first through holes are symmetrical about the center of the adjustment plate 3; a display module can also have four adjustment rods, and the corresponding adjustment plate 3 has four first through holes H1, and the four first through holes H1 are symmetrical about the center of the adjustment plate 3 (such as the four first through holes H1 are located above, below, left, and right of the center of the adjustment plate 3). When the display module has more telescopic rods 4, the adjustment plate 3 also has a corresponding number of first through holes H1, and there is no specific limitation.

[0107] By providing an even number of telescopic rods 4 in the display module, a greater pushing force or pulling force can be generated on the adjustment plate 3 through the second ends 4b of the even number of telescopic rods 4, and the even number of first through holes H1 corresponding to the first ends 4a of the even number of telescopic rods 4 are provided to be symmetrical about the center of the adjustment plate 3, so that the center of gravity of the adjustment plate 3 remains unchanged, thereby preventing the telescopic rods 4 from changing the center of gravity of the adjustment plate 3 and causing it to deviate significantly in the direction of the center of gravity, thereby effectively improving the accuracy of the splicing seam adjustment.

[0108] In addition, the number of telescopic rods 4 included in a display module may also be an odd number, such as 1, 3, 5, etc., and the number of first through holes H1 on the corresponding adjustment plate 3 may also be 1, 3, or 5, and these first through holes H1 are symmetrically arranged about the center of the adjustment plate 3. For example, when the number of first through holes H1 in the adjustment plate 3 is 1, the first through hole H1 coincides with the center of the adjustment plate 3; when the number of first through holes H1 in the adjustment plate 3 is 3, the line connecting the centers of the three first through holes H1 forms an equilateral triangle, and the center of the adjustment plate 3 coincides with the center of the equilateral triangle; when the number of first through holes H1 in the adjustment plate 3 is 5, the line connecting the centers of the five first through holes H1 forms a regular pentagon, and the center of the adjustment plate 3 coincides with the center of the regular pentagon. The same applies to other numbers of first through holes H1 in the adjustment plate 3, and no further details are given here.

[0109] FIG7 is a top view of another adjustment plate according to an embodiment of the present disclosure. The adjustment plate 3 can be circular. Assuming the second end 4b of the telescopic rod 4 is cylindrical, the radius of the adjustment plate 3 is the difference between the length of the telescopic rod 4 in its free state and the radius of the second end 4b. Thus, when the second end 4b of the telescopic rod 4 is outside the adjustment plate 3, the telescopic rod 4 is in its free state. Of course, the adjustment plate 3 can also be rectangular, with the distance from the center of the first through hole H1 to at least one side of the adjustment plate 3 set to the difference between the length of the telescopic rod 4 in its free state and the radius of the second end 4b. When the second end 4b of the telescopic rod 4 is outside the at least one side, the telescopic rod 4 is also in its free state. However, while this approach allows the telescopic rod 4 to be in a free state, the second end 4b of the telescopic rod 4 is susceptible to significant movement when in the free state. For example, when using the adjustment plate 3 shown in FIG7 , the second end 4b of the telescopic rod 4 may rotate around the edge of the adjustment plate 3.

[0110] Please refer to FIG8 , which is a top view of another adjustment plate provided in an embodiment of the present disclosure. The adjustment plate 3 further includes:

[0111] The second hole H3 passes through the adjustment plate 3, and the center distance d2 between the second hole H3 and the first through hole H1 is equal to the length L of the telescopic rod 4 in the free state; the diameter D3 of the second hole H3 is larger than the diameter D2 of the second end 4b;

[0112] After the second end 4b of the telescopic rod 4 is inserted into the second hole H3, the position of the adjustment plate is not fixed, and the adjustment plate 3 is in a floating state.

[0113] Since the central distance d2 between the second hole H3 and the first through hole H1 is equal to the length L of the telescopic rod 4 in the free state, when the second end 4b of the telescopic rod 4 is inserted into the second hole H3, the telescopic rod 4 is in the free state; and since the diameter D3 of the second hole H3 is greater than the diameter D2 of the second end 4b, the second end 4b of the telescopic rod 4 can be separated from the adjustment plate 3, allowing the adjustment plate 3 to freely move in any orientation within the plane where the adjustment plate 3 is located. As shown in FIGS. 9-10, FIG. 9 is a partial schematic view of the second end of the telescopic rod provided by the embodiment of the present disclosure inserted into the second hole, and FIG. 10 is an overall schematic view of the second end of the telescopic rod provided by the embodiment of the present disclosure inserted into the second hole.

[0114] In the embodiment provided by the present disclosure, by providing a second hole H3 on the adjustment plate 3 with a central distance d2 from the first through hole H1 equal to the length L of the telescopic rod 4 in the free state, and making the diameter D3 of the second hole H3 greater than the diameter D2 of the second end 4b, after the second end 4b of the telescopic rod 4 is inserted into the second hole H3, the position of the adjustment plate 3 is not fixed (i.e., the adjustment plate 3 is in a floating state). This can not only prevent the telescopic rod 4 from moving largely in the free state, but also insert the second end 4b of the telescopic rod 4 into the second hole H3 before adjusting the splicing seam, and cooperate with moving the adjustment plate 3 to evaluate which orientation of the first hole H2 the second end 4b of the telescopic rod 4 should be inserted into, thereby reducing the random large-scale movement of the second end 4b of the telescopic rod 4 from affecting the evaluation process, and further improving the adjustment efficiency and accuracy of the splicing seam.

[0115] Please refer to FIG. 11 which is a top view of another adjustment plate provided by the embodiment of the present disclosure. The adjustment plate 3 further includes:

[0116] A third hole H4, spaced from the second hole H3, and the central distance d3 between the third hole H4 and the first through hole H1 is equal to the length L of the telescopic rod 4 in the free state; the diameter D4 of the third hole H4 is substantially the same as the diameter D2 of the second end 4b of the telescopic rod 4. When 0<D2-D4≤0.1mm, it can be considered that the diameter D4 of the third hole H4 is substantially the same as the diameter D2 of the second end 4b.

[0117] After the second end 4b of the telescopic rod 4 is inserted into the third hole H4 of the adjustment plate 3, the position of the adjustment plate 3 is fixed, and at this time, the adjustment plate 3 can be regarded as in a fixed state.

[0118] In the embodiment provided in the present disclosure, by providing the adjustment plate 3 with a telescopic rod 4 that can be inserted when in a free state and making the adjustment plate 3 in a fixed position, the position of the adjustment plate 3 can be fixed by the telescopic rod 4 when the telescopic rod 4 is in a free state, so that the adjustment plate 3 is in a fixed state. In this way, when the display module leaves the factory, the second end 4b of the telescopic rod 4 can be inserted into the third hole H4 to prevent the adjustment plate 3 from shaking or shifting during transportation; and when installing the splicing screen, the second end 4b of the telescopic rod 4 in the display module used as a reference target in the splicing screen can be inserted into the third hole H4 to prevent the reference target from shifting; when adjusting the splicing seam, for the display module that is assessed as not needing to adjust the offset direction, the second end 4b of the telescopic rod 4 can be inserted into the third hole H4, so that the display module that is already precisely positioned can continue to maintain its precise position.

[0119] In other embodiments, some reserved holes may be provided in the adjustment plate 3 for other purposes, which can improve the flexibility of the adjustment plate 3 .

[0120] Please refer to FIG12 for a top view of another adjustment plate provided in an embodiment of the present disclosure. The adjustment plate 3 further includes:

[0121] The first connector 31 is connected to the fixing frame of the splicing screen. The first connector 31 is used to connect the power supply end of the splicing screen and the power supply end of the display panel 1;

[0122] The second connector 32 is connected to the flexible connection line of the display panel 1 and is used to forward communication signals to the display panel 1. The flexible connection line can be a flexible cable for external communication of the display panel 1. The number of second connectors 32 can be determined according to the number of flexible cables.

[0123] In the embodiment provided in the present disclosure, a first connector 31 is provided on the adjustment plate 3, which is connected to the fixed frame of the splicing screen and connects the power supply end of the splicing screen with the power supply end of the display panel 1, and a second connector 32 is connected to the flexible connection line of the display panel 1. The second connector 32 is used to forward the communication signal to the display panel 1, so as to prevent the cable communicating with the display panel 1 from affecting the adjustment plate 3 when adjusting the splicing seam.

[0124] Please refer to FIG13 which is an exploded schematic diagram of a telescopic rod provided in an embodiment of the present disclosure. When the telescopic rod 4 uses spring force to adjust the insertion position of the second end 4b, the telescopic rod 4 includes:

[0125] The housing 41 has a first cavity 411 with one end open and the other closed. The closed end 411a of the first cavity 411 serves as the first end 4a of the telescopic rod 4. A through slot 412 is provided on a side wall of the housing 41 extending in the direction of extension of the housing 41. A second through hole H5 is provided at the closed end 411a of the first cavity 411 and extends through the closed end 411a of the first cavity 411.

[0126] The fixing member 42 is configured to pass through the second through hole H5 and be fixedly connected to the bracket 2;

[0127] The telescopic member 43 is partially accommodated in the first cavity 411 through the open end 411b of the first cavity 411, and can move along the extension direction of the shell 41; the telescopic member 43 has a second cavity 431 with one end open and the other end closed, the open end 431b of the second cavity 431 is accommodated in the first cavity 411, and the closed end 431a of the second cavity 431 is located outside the first cavity 411, and the closed end 431a of the second cavity 431 has a positioning column 432 serving as the second end 4b; a third through hole H6 is provided on the side wall of the open end 431b of the second cavity 431; the first cavity 411 of the shell 41 and the second cavity 431 of the telescopic member 43 are similar in shape, such as square tubes or round tubes, without specific limitation. The positioning column 432 and the closed end 431a of the second cavity 431 can be an integral structure or an independent structure; when the positioning column 432 and the closed end 431a of the second cavity 431 are independent structures, the positioning column 432 and the closed end 431a of the second cavity 431 are fixedly connected.

[0128] At least one elastic device 44 is accommodated in the first cavity 411 , and the elastic device 44 is used to elastically deform along the extension direction of the elastic device 44 ; the elastic device 44 can be a compression spring, a spring, a spring sheet, an elastic rope, etc.

[0129] The spring terminal 45 is located between the elastic member 44 and the telescopic member 43 in the extension direction of the housing 41. A portion of the spring terminal 45 is engaged within the second cavity 431, while the other portion is exposed outside the second cavity 431. A protrusion 451 is provided at the end of the spring terminal 45 exposed outside the second cavity 431. The protrusion 451 passes through the third through-hole H6 and the through-slot 412 and is partially exposed outside the housing 41. The protrusion 451 is used to compress the elastic member 44 in the extension direction of the elastic member 44 to adjust the length of the telescopic member 43 extending into the housing 41. The spring terminal 45 may be V-shaped, with the protrusion 451 located on one side of the V-shaped open end.

[0130] Please refer to FIG14 which is a schematic diagram of the assembly of a telescopic rod provided in an embodiment of the present disclosure.

[0131] Place the elastic device 44 into the first cavity 411 of the housing 41, place a part of the elastic sheet terminal 45 into the second cavity 431 of the telescopic member 43, and let the protrusion 451 on the elastic sheet terminal 45 pass through the third through-hole H6 on the second cavity 431. Then, assemble the telescopic member 43 equipped with the elastic sheet terminal 45 into the first cavity 411 equipped with the elastic device 44, and let the protrusion 451 pass through the through-slot 412 on the first cavity 411, thus forming the telescopic rod 4. If d1 < L, the assembled telescopic rod 4 can transform between the free state and the compressed state (refer to Figure 3). Figures 15 - 16 respectively show the cross-sectional views of the telescopic rod in the compressed state and the free state. After that, align the second through-hole H5 of the telescopic rod 4 with the first through-hole H1 on the adjustment plate 3, and pass the fixing member 42 through the first through-hole H1 and the second through-hole H5 to fixedly connect with the bracket 2.

[0132] If d1 > L, the assembled telescopic rod 4 can transform between the free state and the stretched state.

[0133] In the embodiment provided by the present disclosure, by setting the telescopic rod 4 to include the housing 41, the elastic device 44 located in the first cavity 411 of the housing 41, the telescopic member 43 that matches the housing 41, and the elastic sheet terminal 45 partially located in the second cavity 431 of the telescopic member 43, the telescopic rod 4 can move freely in the extending direction of the telescopic rod 4, which is convenient for adjusting the length of the telescopic rod 4 and making the second end 4b of the telescopic rod 4 easy to insert into the first hole H2, the second hole H3, the third hole H4, etc.

[0134] Please refer to Figure 17, which is a schematic diagram of the position where the telescopic rod and the bracket are fixedly connected provided by the embodiment of the present disclosure.

[0135] The bracket 2 is provided with a mounting post 21 at the position where it is connected to the telescopic rod 4. The mounting post 21 is arranged on the side of the bracket 2 facing the telescopic rod 4 and protrudes from the surface of the bracket 2 body; the mounting post 21 passes through the first through-hole H1 and is arranged with a clearance from the first through-hole H1;

[0136] The mounting post 21 is provided with a fixing hole 211 on the side facing the telescopic rod 4. The fixing hole 211 cooperates with the fixing member 42 to fixedly connect the first end 4a of the telescopic rod 4 with the mounting post 21 and can rotate around the fixing member 42.

[0137] As shown in Figure 17 , by providing a mounting post 21 protruding from the surface of the bracket 2 body, and allowing the mounting post 21 to pass through the first through hole H1 with a gap therebetween, the adjustment plate 3 can be ensured to have space to move in different directions within the plane of the adjustment plate 3, thereby facilitating adjustment of the joint seam. Furthermore, a fixing hole 211 is provided on the side of the mounting post 21 facing the telescopic rod 4. A fixing member 42 cooperates with the fixing hole 211 to securely connect the first end 4a of the telescopic rod 4 to the mounting post 21 and allows rotation about the fixing member 42, thereby enabling the telescopic rod 4 to be rotated to any position and inserted into the first hole H2, second hole H3, third hole H4, etc. in the adjustment plate 3. Figure 18 shows a three-dimensional cross-sectional view of the fixed connection between the telescopic rod and the bracket according to an embodiment of the present disclosure.

[0138] Please continue to refer to FIG17 , the mounting post 21 is indented near one end of the adjustment plate 3 ;

[0139] The diameter D5 of the first through hole H1 is greater than the first value and smaller than the second value; wherein the first value is the diameter D6 of one end of the mounting post 21 that is indented, and the second value is the diameter D7 of the other end of the mounting post 21 that is away from the indented setting;

[0140] The height h1 of one end of the mounting post 21 that is set back is greater than the thickness h2 of the adjustment plate 3 .

[0141] In the embodiment provided by the present disclosure, by setting the mounting post 21 indented at one end close to the adjustment plate 3; and making the diameter D5 of the first through hole H1 larger than the diameter D6 of the indented end of the mounting post 21, and smaller than the diameter D7 of the other end of the mounting post 21 away from the indented end; at the same time, making the height h1 of the indented end of the mounting post 21 larger than the thickness h2 of the adjustment plate 3, the adjustment plate 3 can be floatingly connected to the telescopic rod 4 and the bracket 2, so that the offset position of the adjustment plate 3 can be changed by the adjustment plate 3 and the telescopic rod 4, thereby driving the entire display module to produce a corresponding offset to adjust the splicing seam.

[0142] The difference between the height h1 of the indented end of the mounting post 21 and the thickness h2 of the adjustment plate 3 is at least 0.15 mm, that is, h1 − h2 ≥ 0.15 mm.

[0143] Based on the same inventive concept, an embodiment of the present disclosure provides a splicing screen. FIG19 is a schematic structural diagram of a splicing screen provided by an embodiment of the present disclosure. The splicing screen includes:

[0144] Fixed frame 100;

[0145] There are multiple display modules 200 as above. The specific structure of the display module 200 can be found in the relevant introduction of the display module 200 above and will not be repeated here. The bracket of the display module 200 has a mounting hole H7 on at least one diagonal corner that is movably connected to the fixed frame 100. The size of the fixed frame 100 is m times the size of the display module 200, where m is the total number of the multiple display modules 200 and m is greater than 1.

[0146] The mounting hole H7 may be a rectangular through hole, so that the display module 200 can have a movable margin in a plane parallel to the fixed frame 100 when adjusting the joint seam. After the joint seam adjustment is completed, the display module 200 is fastened to the fixed frame 100 through the mounting hole H7.

[0147] Please refer to Figure 20 for a top view of a fixed frame provided in an embodiment of the present disclosure. The fixed frame 100 includes a third connector 101, which is used to dock with the first connector. After the third connector 101 is connected to the first connector, the positions of the adjustment plate and the fixed frame 100 are relatively fixed.

[0148] After the third connector 101 on the fixed frame 100 is connected to the first connector on the adjustment plate, the positions of the adjustment plate and the fixed frame 100 will be relatively fixed. When the second end of the telescopic rod is inserted into any positioning hole, the first end of the telescopic rod will push the bracket to drive the display panel to the direction or opposite direction of the positioning hole where the second end is inserted, thereby reducing the width of the splicing seam between adjacent display modules 200 in the splicing screen and improving the splicing effect.

[0149] In some embodiments, after the third connector 101 is connected to the first connector, they can still move relative to each other in a plane parallel to the display module 200. By adjusting the telescopic rod, the display module 200 can cause the adjustment plate to drive the display module 200 to move in a direction parallel to the display module 200. Therefore, the superposition of the two movements can increase the range of adjustment of the splicing seam.

[0150] The above-mentioned splicing screen can be an LED splicing screen, a MicroLED splicing screen, an OLED splicing screen, an LCD splicing screen, etc., without specific limitation.

[0151] Based on the same inventive concept, an embodiment of the present disclosure provides a method for adjusting a splicing seam in a splicing screen. FIG21 is a flow chart of a method for adjusting a splicing seam in a splicing screen provided by an embodiment of the present disclosure. The method includes:

[0152] Step S11: placing the second ends of the telescopic rods in the plurality of display modules outside the first holes;

[0153] Step S12: Select one of the multiple display modules as a reference target. Starting from the display module adjacent to the reference target, adjust the splicing seam between adjacent two display modules one by one to make the splicing seam smaller than a preset value;

[0154] Among them, adjusting the splicing seam between adjacent two display modules includes:

[0155] Evaluate the deviation direction of the display module close to the outer edge of the fixed frame among the adjacent two display modules when making the splicing seam between the adjacent two display modules smaller than the preset value;

[0156] Insert the second end of the telescopic rod in the display module close to the outer edge into the first hole in the same or opposite direction as the deviation direction; among them, if the center distance between the first through hole and the first hole is less than the length of the telescopic rod in the free state, the second end is inserted into the first hole in the same direction as the deviation direction; if the center distance between the first through hole and the first hole is greater than the length of the telescopic rod in the free state, the second end is inserted into the first hole in the opposite direction to the deviation direction.

[0157] The above method for adjusting the splicing seam in the splicing screen can be implemented by the assembly personnel on-site when assembling the splicing screen, or can be implemented by robots, robotic arms, etc. in the factory.

[0158] In some embodiments, to place the second end of the telescopic rod in the multiple display modules outside the first hole, it can also be achieved by the following method:

[0159] Insert the second end of the telescopic rod in the reference target into the third hole;

[0160] When evaluating the size of the splicing seam, or when it is evaluated that the adjacent display modules do not deviate, insert the second end of the telescopic rod in the adjacent display modules into the second hole.

[0161] If the third hole and the second hole are not provided in the adjustment plate, placing the second end of the telescopic rod outside the first hole means placing the second end of the telescopic rod outside the adjustment plate.

[0162] Taking the adjustment plate including the third hole, the second hole, and d1 < L as an example, please refer to FIG. 22 which is a schematic diagram of adjusting the splicing seam in a splicing screen provided by an embodiment of the present disclosure.

[0163] S21: Insert the second end of the telescopic rod in the display module serving as a reference target into the third hole so that the reference target does not shift and its position is fixed; pre-install an adjacent display module 200 next to the reference target, and insert the second end of the telescopic rod in the display module 200 into the second hole so that the display module 200 can move freely in a direction parallel to the plane where the display module is located. By observation or measurement, it can be determined that the display module 200 deviates from the reference target toward the lower right corner, and then it is evaluated and determined that the second end of the telescopic rod in the display module 200 needs to be inserted into the first hole in the lower right position.

[0164] During pre-installation, the display module 200 is connected to the corresponding mounting holes of the fixing frame but can be moved parallel to the plane where the display module is located.

[0165] S22: According to the evaluation result of S21, the second end of the telescopic rod of the display module 200 is inserted into the first hole at the upper left position. Then, the display module 200 is fastened to the corresponding mounting hole of the fixing frame.

[0166] Please refer to Figures 23-25, Figure 23 is a schematic diagram of a pre-installed display module provided in an embodiment of the present disclosure, Figure 24 is a schematic diagram of the pre-installed display module in Figure 23 after adjusting the corresponding splicing seam provided in an embodiment of the present disclosure, Figure 25 is a schematic diagram of another pre-installed display module provided in an embodiment of the present disclosure, and Figure 26 is a schematic diagram of the pre-installed display module in Figure 25 after adjusting the corresponding splicing seam provided in an embodiment of the present disclosure.

[0167] Assuming that a splicing screen consisting of four display modules needs to be installed, the display modules used can be set to the eight directions as shown in Figure 4. For example, two display modules (i.e., the reference target and display module 200-1) are installed using the same method as steps S21-S22, and the splicing seam between them is adjusted.

[0168] As shown in Figure 23 , the second end of the telescopic rod in display module 200-2 is inserted into the second hole, allowing display module 200-2 to move freely in a direction parallel to the plane of display module 200-2. By observation or measurement, it can be determined that display module 200-2 deviates downward from a reference target, and thus, it is determined that the second end of the telescopic rod in display module 200-2 should be inserted into the first hole in the downward direction. Based on this evaluation result, as shown in Figure 24 , the second end of the telescopic rod in display module 200-2 is inserted into the first hole in the downward direction.

[0169] As shown in FIG. 25, insert the second end of the telescopic rod in the display module 200-3 into the second hole, so that the display module 200-3 can move freely in the direction parallel to the plane where the display module 200-3 is located. By observation or measurement, it can be determined that the display module 200-3 deviates downward from the display module 200-1 and is too close to the display module 200-2 on the left. Then, it is evaluated and determined that the second end of the telescopic rod in the display module 200-3 needs to be inserted into the first hole in the lower left position. As shown in FIG. 26, according to the above evaluation result, insert the second end of the telescopic rod in the display module 200-3 into the first hole in the lower left position.

[0170] Please refer to FIG. 27, which is another schematic diagram of pre-installing another display module provided by an embodiment of the present disclosure, and FIG. 28, which is a schematic diagram of adjusting the splicing seam corresponding to the pre-installed another display module in FIG. 27 provided by an embodiment of the present disclosure.

[0171] Assume that when the display module 200-3 in FIG. 25 is pre-installed on the fixed frame of the splicing screen, the corresponding pre-installed position is as shown in FIG. 27. By observation or measurement, it can be determined that the display module 200-3 does not deviate, and then it is evaluated and determined that the second end of the telescopic rod in the display module 200-3 needs to be inserted into the third hole. As shown in FIG. 28, according to the above evaluation result, insert the second end of the telescopic rod in the display module 200-3 into the third hole.

[0172] If the display module needs to be set to other orientations, for the situation of inserting the second end of the telescopic rod in the display module, please refer to FIGS. 29-33, which are schematic diagrams of setting the display module to a specific orientation provided by an embodiment of the present disclosure. Among them, FIG. 29 shows that the second end of the telescopic rod in the display module 200 is inserted into the first hole on the right to offset the display module to the left; FIG. 30 shows that the second end of the telescopic rod in the display module 200 is inserted into the first hole in the upper left to offset the display module to the lower right; FIG. 31 shows that the second end of the telescopic rod in the display module 200 is inserted into the first hole above to offset the display module downward; FIG. 32 shows that the second end of the telescopic rod in the display module 200 is inserted into the first hole in the upper right to offset the display module to the lower left; FIG. 33 shows that the second end of the telescopic rod in the display module 200 is inserted into the left to offset the display module to the right.

[0173] From the above embodiments, it can be seen that if d1 < L, the first hole into which the display module 200 inserts the second end of the telescopic rod is the orientation in which the display module deviates from the adjacent display module, and the display module 200 offsets to the opposite orientation of the first hole into which the second end of the telescopic rod is inserted. This method is more in line with the operation habits of assembly workers and is not prone to assembly errors.

[0174] Similarly, it can be known that if d1 > L, the first hole into which the display module 200 inserts the second end of the telescopic rod is the opposite orientation in which the display module deviates from the adjacent display module, and the display module 200 offsets to the orientation of the first hole into which the second end of the telescopic rod is inserted.

[0175] In actual applications, the number of display modules that make up the spliced ​​screen may be greater. A similar method can be used to assemble the display modules and adjust the splicing seams. The reference target in the spliced ​​screen can be located at a corner of the fixed frame as shown in the previous embodiment, or at any other location within the fixed frame. This is not a limitation.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the present disclosure.

[0177] Obviously, those skilled in the art may make various changes and modifications to the present disclosure without departing from the spirit and scope of the present disclosure. Thus, if these modifications and variations of the present disclosure fall within the scope of the claims of the present disclosure and their equivalents, the present disclosure is intended to include these modifications and variations.
