The following will be combined with the accompanying drawings to describe the present application in detail.

[0045] The present application provides a spliced display device, a display device splicing jig and a display device splicing method. The following will be combined with the accompanying drawings to describe the present application in detail.

[0046] The present application provides a spliced display device, a display device splicing jig and a display device splicing method. The following will be combined with the accompanying drawings to describe the present application in detail.

[0047] In some optional embodiments, the screen body 1 has a middle area A1 and at least two corner areas A2 surrounding the middle area A1, and the at least partial first limiting piece 2 is located at the corner area A2 of the screen body 1.

[0048] It should be noted that, for example, when the screen body 1 is in a rectangular shape, the screen body 1 has four corner areas A2, i.e., four right angles of the rectangle. When the first limiting piece 2 is arranged at each of the four right angles of the rectangle, the first limiting piece 2 is also in a rectangular shape. By extending the first limiting piece 2 relative to the screen body 1 by a predetermined distance towards the adjacent screen assembly 10, the extension of the first limiting piece 2 relative to the direction perpendicular to the straight angle side by a predetermined distance is limited, and thus the gap between the adjacent sides of the screen body 1 of the adjacent screen assembly 10 when the screen body 1 is in a rectangular shape is limited, thereby improving the overall assembly precision of the display device in each direction, and not being limited to the precision control in a single direction.

[0049] Of course, the shapes of the screen body 1 and the first limiting piece 2 are not limited to the above embodiments, and can also be trapezoidal, rhombic, etc., without special limitation.

[0050] In order to splice the display device into a display device with a larger size, such as a large screen of 100 inches or more than 200 inches, a two-time splicing mode can be used. Please refer to Figure 4 In some optional embodiments, the screen assembly 10 further comprises a support 4 arranged between the first limiting piece 2 and the screen body 1. Optionally, the single screen assembly 10 comprises at least two screen bodies 1, and each screen body 1 of the single screen assembly 10 is fixed to the same support 4.

[0051] It can be understood that the single screen assembly 10 can comprise a plurality of screen bodies 1, and each screen body 1 is fixed by the same support 4, i.e., the single screen assembly 10 is also spliced by a plurality of screen bodies 1. Each screen body 1 can be fixed between the screen body 1 and the support 4 by an adhesive layer 41, such as double-sided adhesive or other liquid adhesive. Unlike the connection between the adjacent screen assemblies 10 by the connecting piece 5, the screen assembly 10 is directly connected to the support 4 by the adhesive layer 41, which is not easy to cause damage to the screen body 1.

[0052] The support 4 can be a glass-based support plate, which can be a reinforced glass material to ensure the structural strength. The alignment precision between the screen bodies 1 and between the screen body 1 and the support 4 can be achieved by using a device for aligning and bonding the color film substrate and the array substrate, and the bonding precision can reach microns.

[0053] The high-precision lamination device can realize ultra-narrow and uniform seams between the screen bodies 1 in a single screen assembly 10, and there is no risk of collision between the screen bodies 1. In addition, the support 4 can provide micron-level flatness, so that the seams between the screen bodies 1 in the single screen assembly 10 are ultra-narrow, uniform, and have good flatness. However, due to the micron-level flatness requirement of the support 4, and due to the inherent limitations of the strengthened glass used in the support 4, the size of the glass-based support 4 cannot be too large (commonly 30-40 inches), so that a large screen of 100 inches or more than 200 inches needs to be further spliced. Specifically, at least two screen bodies 1 are spliced into a screen assembly 10 on the support 4, and then multiple screen assemblies 10 are spliced to obtain a large-size spliced display device.

[0054] As shown in Figure 3 In order to avoid the influence of the support 4 on the gap size between the screen bodies 1 of the adjacent two screen assemblies 10, in some optional embodiments, the orthogonal projection of the support 4 on the first limiting piece 2 does not exceed the orthogonal projection of the screen body 1 on the first limiting piece 2 in the thickness direction of the spliced display device.

[0055] It can be understood that when the single screen assembly has multiple screen bodies 1, the orthogonal projection of the support 4 on the first limiting piece 2 does not exceed the orthogonal projection of all screen bodies 1 in the single screen assembly 10 on the first limiting piece 2, that is, the support 4 does not protrude relative to any screen body 1, and the size of the support 4 can be smaller than the size of the whole obtained by splicing the screen bodies 1 in the single screen assembly 10, so that the FPC (Flexible Printed Circuit) or COF (Chip flexible printed circuit) of the screen body 1 is exposed from the side of the support 4, facilitating subsequent electrical connection with the chip. Optionally, the support 4 is provided with a slot for the FPC or COF of the screen body 1 to extend out of.

[0056] Optionally, the first limiting piece 2 extends a predetermined distance of 10-60 μm relative to the screen body 1 to the adjacent screen assembly 10, and the gap between the screen bodies 1 of the adjacent two screen assemblies 10 is 20-120 μm.

[0057] It can be understood that the smaller the predetermined distance by which the first limiting piece 2 extends relative to the screen body 1 to the adjacent screen assembly 10, the smaller the gap between the screen bodies 1 of the adjacent two screen assemblies 10, and the better the display effect of the spliced display device, but it is limited by the relative position accuracy of the first limiting piece 2 and the screen body 1.

[0058] Optionally, the first limiting member 2 extends a predetermined distance of 50 μm from the screen body 1 to the adjacent screen assembly 10, and when the two first limiting members 2 abut and extend a predetermined distance from the screen body 1, the gap between the screen bodies 1 of the corresponding adjacent two screen assemblies 10 is 100 μm. According to the inventor's repeated experiments, when the first limiting member 2 extends a predetermined distance of 50 μm from the screen body 1 to the adjacent screen assembly 10, the machining tolerance of the first limiting member 2 is ± 5 μm, and the actual gap between the screen bodies 1 of the corresponding adjacent two screen assemblies 10 fluctuates between 90 μm and 110 μm, that is, the machining error is ± 10 μm.

[0059] In the prior art, the gap between the display screens fluctuates between 0 and 220 μm, which is much larger than the gap between the screen bodies 1 of the adjacent two screen assemblies 10 in the embodiment of the present application. The present application can effectively reduce and stabilize the gap between the screen bodies 1 of the adjacent two screen assemblies 10, and effectively reduce the processing cost.

[0060] As shown in Figure 1 and Figure 5 In order to improve the connection stability between the first limiting member 2 and the support member 4, in some optional embodiments, the screen assembly 10 further comprises a fixing member 3, which is arranged on the side of the support member 4 away from the screen body 1, and the fixing member 3 is connected with the first limiting member 2 and the support member 4, respectively.

[0061] It should be noted that the first limiting member 2 and the fixing member 3 can be made of metal to ensure the structural strength of the screen assembly 10 and avoid deformation or damage. The fixing member 3 is connected with the first limiting member 2 and the support member 4, respectively, that is, the three are connected to form an integral structure, which is convenient for subsequent mutual connection between the screen assemblies 10. Considering that the first limiting member 2 and the fixing member 3 are usually made of metal, and the support member 4 is made of a fragile material such as glass, the first limiting member 2 and the fixing member 3 can be connected by bolts, positioning pins, etc., and the fixing member 3 and the support member 4 can be fixed by adhesive, such as double-sided tape or other liquid adhesive, to avoid damage to the support member 4.

[0062] Optionally, the fixing member 3 has a frame structure, which includes a corner portion 32 and a main body portion 31 connected with each other, and the corner portion 32 is connected with the first limiting member 2. Optionally, the corner portion 32 has a mounting groove, so that the first limiting member 2 is partially embedded in the corner portion 32, as shown in Figure 5As shown, the body part 31 is connected to the support 4, so as to facilitate the connection between the body part 31 and the support 4. The body part 31 can be connected to the support 4 by using double-sided adhesive tape. Specifically, the body part 31 can be in the shape of a cross, and a slot is formed between the body part 31 and the corner part 32, so as to facilitate the FPC and COF of the body part 1 to extend out while reducing the weight. Threaded holes can be correspondingly arranged between the corner part 32 and the first limiting part 2, and the two are fixedly connected by bolts.

[0063] As shown in Figure 2 and Figure 6 In order to realize the splicing between adjacent screen body assemblies 10, in some optional embodiments, the adjacent screen body assemblies 10 are connected by at least two connecting parts 5. It can be understood that the more the number of connecting parts 5 arranged, the better the connection effect between the adjacent screen body assemblies 10, but the size of the connecting part 5 and the size of the space on the screen body assembly 10 capable of connecting the connecting part 5 need to be considered.

[0064] Optionally, the fixing part 3 is provided with a connecting hole connected with the connecting part 5, and the connecting part 5 is connected with the connecting holes on the fixing parts 3 of the adjacent two screen body assemblies 10, so as to realize the splicing of the adjacent two screen body assemblies 10.

[0065] Specifically, the connecting part 5 includes a connecting seat 51 and at least two connecting bolts 52 arranged on the connecting seat 51, and the connecting hole on the fixing part 3 is a threaded hole corresponding to the connecting bolt 52 on the connecting seat 51, and each connecting bolt 52 on the connecting seat 51 is connected to the fixing part 3 of a different screen body assembly 10, so as to realize the connection of the adjacent two screen body assemblies 10. It can be understood that, as shown in Figure 2 The adjacent two screen body assemblies 10 can be two adjacent screen body assemblies 10 in the horizontal direction X, or two adjacent screen body assemblies 10 in the vertical direction Y, and there is no special limitation, and they can all be connected by the connecting part 5.

[0066] Please refer to Figures 7 to 8 The embodiment of the application also provides a display device assembling jig for realizing the assembling of the display device. The display device assembling jig comprises: a table body 6 for placing the screen body assembly 10 in the above-mentioned embodiment; and a second limiting part 7 arranged on the table body 6, wherein the second limiting part 7 has an abutting surface P, and the abutting surface P comprises a first abutting surface P1 and a second abutting surface P2. The first abutting surface P1 protrudes outward by a predetermined distance relative to the second abutting surface P2, and the first abutting surface P1 is used for abutting to the body part 1 of the screen body assembly 10, and the second abutting surface P2 is used for abutting to the first limiting part 2 of the screen body assembly 10.

[0067] The display device assembling jig provided by the embodiment of the present application comprises a table body 6 and a second limiting piece 7, a first abutting surface P1 of the second limiting piece 7 protrudes outward by a predetermined distance relative to a second abutting surface P2, that is, when the first limiting piece 2 abuts against the second abutting surface P2 and the screen body 1 abuts against the first abutting surface P1, the first limiting piece 2 extends outward by a predetermined distance relative to the screen body 1, the extension distance of the first limiting piece 2 relative to the screen body 1 is accurately defined by the two abutting surfaces P of the second limiting piece 7, and then the gap size between the screen bodies 1 of the two adjacent screen body assemblies 10 is accurately controlled, so that the phenomenon of extrusion or uneven gap between the screen bodies 1 of the two adjacent screen body assemblies 10 due to too small gap is avoided, and the yield of the assembled display device is improved.

[0068] It can be understood that the table body 6 of the display device assembling jig is a carrier for carrying the screen body assembly 10 and the second limiting piece 7, and the table body 6 usually has a flat plane to place the screen body assembly 10.

[0069] When the screen body 1 and the first limiting piece 2 are both in rectangular shape, in order to better abut and fit with the screen body 1 and the first limiting piece 2, the second limiting piece 7 is in L-shaped structure, and the abutting surface P is formed on the inner side surface of the L-shaped structure, that is, the abutting surface P comprises two planes which are connected and have a right angle, so as to correspond to the right angle edges of the screen body 1 and the first limiting piece 2. Of course, according to the different shapes of the screen body 1, the shape of the second limiting piece 7 also needs to be adjusted correspondingly, so that the second limiting piece 7 can stably fix the screen body 1.

[0070] In order to facilitate the second limiting piece 7 to fix different screen bodies 1, in some optional embodiments, the second limiting piece 7 and the table body 6 are detachably connected.

[0071] It should be noted that when the second limiting piece 7 abuts against the screen body 1 and the first limiting piece 2, the second limiting piece 7 can be fixed by means of bolt fixing or other detachable connection, so as to avoid the relative displacement of the second limiting piece 7 and the screen body 1 and the first limiting piece 2, which affects the subsequent alignment accuracy, and after the assembling of the screen body assembly 10 on the table body 6 is completed, the connection between the second limiting piece 7 and the table body 6 can be released, and the assembling of another screen body assembly 10 can be continued.

[0072] Optionally, the second limiting member 7 and the table body 6 are magnetically connected, specifically, the second limiting member 7 and the table body 6 can be made of magnetic members, or a magnetic member is arranged on the second limiting member 7, so that the second limiting member 7 can be adsorbed on the table body 6. Of course, the second limiting member 7 and the table body 6 can also be connected in other ways, for example, the second limiting member 7 and the table body 6 are connected by gas adsorption, specifically, a gas suction hole is arranged on the table body 6 corresponding to the position of the second limiting member 7, and the second limiting member 7 is fixed by the suction force of the gas suction hole.

[0073] Please refer to Figure 11 and Figure 12 In order to make the first abutting surface P1 and the second abutting surface P2 of the second limiting member 7 can be in close contact with the screen body 1 and the first limiting member 2 respectively, in some optional embodiments, the display device assembling jig further comprises an elastic member 8, the elastic member 8 is movably connected with the table body 6 and the second limiting member 7 respectively, so that the second limiting member 7 abuts against the screen body 1 and the first limiting member 2.

[0074] It should be noted that the elastic member 8 can be a spring or a Z-shaped elastic sheet, and the elastic member 8 is movably connected with the table body 6 and the second limiting member 7 respectively, and the elastic member 8 is in a compressed state, so that the elastic member 8 can abut against the second limiting member 7 to prevent the second limiting member 7 from moving. Optionally, the table body 6 is provided with a threaded hole structure (i.e. the protruding structure on the four corners of the table body 6), which is connected by a fixing bolt S and a threaded hole, the top end of the fixing bolt S is in contact with the elastic member 8, and the elastic member 8 is at least partially located in the threaded hole. Optionally, the second limiting member 7 is provided with a limiting groove 71 for fixing the elastic member 8, and the top end of the elastic member 8 extends into the limiting groove 71, so as to limit the relative displacement of the elastic member 8 through the limiting groove 71, thereby improving the stability of the fixation of the second limiting member 7.

[0075] Please refer to Figures 9 to 19 The embodiment of the application further provides a assembling method for assembling a display device, comprising:

[0076] S110: providing a display device assembling jig, the display device assembling jig is any one of the display device assembling jigs in the above embodiments, placing the screen body 1 on the table body 6 of the display device assembling jig, and abutting the first abutting surface P1 of the second limiting member 7 of the display device assembling jig against the screen body 1, as shown in Figures 10 to 12 . Figure 10 The structure schematic view when the screen body 1 is placed on the table body 6 of the display device assembling jig is shown; Figure 11 The installation process of fixing the second limiting member 7 by the elastic member 8 arranged between the table body 6 and the second limiting member 7 is shown, and the elastic member 8 can be a spring or a Z-shaped elastic sheet; Figure 12The structure diagram after the elastic member 8 is installed is shown.

[0077] S120: Place the first limiting member 2 on the backlight side of the screen body 1, and make the second abutting surface P2 of the second limiting member 7 abut on the first limiting member 2, as shown in Figure 13 The second limiting member 7 abuts on the first limiting member 2.

[0078] S130: Relatively fix the first limiting member 2 and the screen body 1, and remove the second limiting member 7, so that the first limiting member 2 and the screen body 1 form the screen assembly 10, as shown in Figures 14 to 19 and Figure 1 The first limiting member 2 and the screen body 1 are relatively fixed. Figure 14 The first limiting member 2 and the screen body 1 are relatively fixed.

[0079] S140: Connect each screen assembly 10, and make the first limiting members 2 of the two adjacent screen assemblies 10 abut on each other, so that the screen body 1 of the two adjacent screen assemblies 10 form a gap, as shown in Figure 2 The first limiting members 2 of the two adjacent screen assemblies 10 abut on each other.

[0080] The assembling method of the assembled display device provided by the embodiment of the present application uses the second limiting piece 7 of the display device assembling jig to limit the protruding distance of the first limiting piece 2 relative to the screen body 1 to the direction of the screen assembly 10 to be spliced, and the first limiting pieces 2 of the adjacent two screen assemblies 10 are abutted against each other, that is, the first limiting pieces 2 of the adjacent two screen assemblies 10 are in contact without gap, so that a gap is formed between the screen bodies 1 of the adjacent two screen assemblies 10, and the size of the gap is equal to the sum of the predetermined distances of the two abutted first limiting pieces 2 extending outward relative to the screen body 1, so that the size of the gap between the screen bodies 1 of the adjacent two screen assemblies 10 can be accurately controlled by the first limiting piece 2, avoiding the extrusion or uneven gap between the screen bodies 1 of the adjacent two screen assemblies 10 due to the too small gap, and improving the yield of the spliced display device.

[0081] In step S110, at least two screen bodies 1, for example, four screen bodies 1, are first fixed on the same support 4 by bonding or the like, and the support 4 can be a glass-based support plate, which can be made of reinforced glass material, and then the assembly of the screen body 1 and the support 4 is fixed on the display device assembling jig, and the first abutting surface P1 of the second limiting piece 7 abuts against the edge or corner of the whole obtained by splicing the screen body 1 in a single screen assembly 10.

[0082] In step S120, the second abutting surface P2 of the second limiting piece 7 abuts against the first limiting piece 2, so that the first limiting piece 2 extends outward relative to the screen body 1 by a predetermined distance, that is, the distance of the first abutting surface P1 protruding outward relative to the second abutting surface P2.

[0083] In step S130, the first limiting piece 2 and the screen body 1 can be connected by the fixing piece 3 to make the first limiting piece 2 and the screen body 1 relative, to form the screen assembly 10, and then the second limiting piece 7 is removed, that is, the limitation of the second limiting piece 7 on the screen assembly 10 is released, so that the screen assembly 10 can be taken out from the display device assembling jig, which is convenient for further assembling the screen assembly 10.

[0084] In step S140, the adjacent screen bodies 1 can be connected by the connecting piece 5 to splice the plurality of screen bodies 1 to form a larger display device, the first limiting pieces 2 of the adjacent two screen assemblies 10 abut against each other, that is, the gap between the first limiting pieces 2 of the adjacent two screen assemblies 10 is 0, and then the size of the gap between the screen bodies 1 of the adjacent two screen assemblies 10 is equal to the sum of the predetermined distances of the two abutted first limiting pieces 2 extending outward relative to the screen body 1, so that the accurate control of the gap between the screen bodies 1 of the adjacent two screen assemblies 10 is realized.

[0085] In some alternative embodiments, between the steps of placing the screen body 1 on the table body 6 and relatively fixing the first limiting member 2 and the screen body 1, further comprising: clamping and fixing the first limiting member 2 and the second limiting member 7 by the clamping member 9, as shown in Figure 15 and 16 .

[0086] It can be understood that the clamping member 9 is arranged to ensure that the first limiting member 2 can be tightly attached to the second limiting member 7, that is, to ensure that the first limiting member 2 can be completely attached to the second abutting surface P2 of the second limiting member 7, and to accurately control the first limiting member 2 to extend a predetermined distance outside the screen assembly 10, as shown in Figure 17 Alternatively, the clamping member 9 can include two intersecting “[” shaped structural members, the two ends of the “[” shaped structural members are respectively clamped on the opposite surfaces of the first limiting member 2 and the second limiting member 7, and the clamping member 9 can be fixed by bolts or other components and the first limiting member 2 or the second limiting member 7.

[0087] In some alternative embodiments, in the step of relatively fixing the first limiting member 2 and the screen body 1, comprising: connecting the fixing member 3 with the first limiting member 2 and the support member 4 of the screen body 1 respectively, so as to relatively fix the first limiting member 2 and the screen body 1.

[0088] The fixing member 3 is connected with the first limiting member 2 and the support member 4 respectively, that is, the three are connected to form an integral structure, which is convenient for subsequent mutual connection between the screen assemblies 10. Considering that the first limiting member 2 and the fixing member 3 are usually made of metal, and the support member 4 is made of glass or other fragile materials, the first limiting member 2 and the fixing member 3 can be connected by bolts, positioning pins or other connection methods, and the fixing member 3 and the support member 4 can be fixed by adhesive, such as double-sided adhesive or other liquid adhesive, so as to avoid damage to the support member 4.

[0089] In some alternative embodiments, the specific assembly process of the assembled display device is as follows:

[0090] Firstly, the screen body 1 is provided, which can be a glass-based display screen with a back surface having a binding FPC or COF.

[0091] Secondly, at least two screen bodies 1 are attached to a glass-based support member 4 (strengthened glass) by using a device for splicing and aligning, and the size of the glass-based support member 4 is smaller than the overall size of the screen body 1. The alignment accuracy between the screen bodies 1 and between the screen body 1 and the support member 4 can be achieved by using a device for aligning and attaching the color film substrate and the array substrate, and the attachment accuracy can reach micrometer level. The screen body 1 and the support member 4 can be fixed by an adhesive layer 41, such as double-sided adhesive or other liquid adhesive, and are not limited in particular, as shown in Figure 4 .

[0092] Thirdly, the assembly of the support 4 and the at least two screen body 1 is placed on the table body 6, the display side of the screen body 1 faces the table body 6, and then the four corners of the screen body 1 are abutted by the first abutting surface P1 of the second limiting piece 7, and the second limiting piece 7 and the table body 6 can be connected by a magnet, as shown in Figure 10

[0093] Fourthly, the elastic piece 8 between the table body 6 and the second limiting piece 7 is installed, and the elastic piece 8 can be a spring or a Z-shaped elastic sheet, and when the spring is used, the spring is placed in the limiting groove 71 on both sides of the second limiting piece 7. Then the spring is forced by tightening the fixing bolt S, and the second limiting piece 7 is moved, and the second limiting piece 7 clamps the screen assembly 10 by tightening the spring of the table body 6, as shown in Figure 11 and 12

[0094] Fifthly, the first limiting piece 2 is placed, and then the first limiting piece 2 and the second limiting piece 7 are clamped by the clamping piece 9. The final effect is that the first abutting surface P1 abuts the screen body 1, and the first abutting surface P1 abuts the first limiting piece 2, so that the four corners of the first limiting piece 2 are single-sidedly beyond the screen body 1 in the single screen assembly 10 by the same predetermined distance, for example, 50 μm, and at this time, the positions of the screen assembly 10, the first limiting piece 2 and the second limiting piece 7 are in a relatively clamped and fixed state, as shown in Figure 13

[0095] Sixthly, after the positions of the screen assembly 10, the first limiting piece 2 and the second limiting piece 7 are in a relatively clamped and fixed state, the fixing piece 3 is connected with the first limiting piece 2 and the support 4 respectively, and the fixing piece 3 and the support 4 can be bonded by adhesive tape, and the fixing piece 3 and the first limiting piece 2 can be locked together by a locking piece such as a bolt, so that the fixing piece 3, the first limiting piece 2 and the support 4 are fixed as a whole, as shown in Figure 18

[0096] Seventhly, the PCBA is locked to the fixing piece 3 by a locking piece such as a bolt, and then the screen assembly 10 is taken off from the display device assembling jig, and then the screen assemblies 10 are connected by the connecting piece 5 to form the required assembled display device, as shown in Figure 19
