Display modules and video walls

Abstract

This application discloses a display module and a splicing screen, belonging to the field of display technology. The display module includes a support plate, a display panel, and a protective bracket. Both the second panel portion of the display panel and the protective bracket can be disposed within a bearing groove of the support plate, and at least a portion of the second panel portion can be located between the protective bracket and the bottom surface of the bearing groove. Thus, the protective bracket protects the side of the second panel portion of the display panel facing away from the bottom surface of the bearing groove. During the subsequent splicing of multiple display modules, the side of the second panel portion of each display module facing away from the bottom surface of the bearing groove is less likely to collide with adjacent display modules, reducing the probability of breakage of the fan-out leads integrated within the second panel portion, thereby enabling the display module to display images normally. Therefore, the splicing screen obtained by splicing multiple display modules has high reliability.

Description

Technical Field

[0001] This application relates to the field of display technology, and in particular to a display module and a video wall. Background Technology

[0002] A video wall is composed of multiple display modules, each of which can independently display images. The display surfaces of these multiple modules face the same direction, and their display areas together form the display area of ​​the video wall.

[0003] To minimize the gap between two adjacent display modules in a video wall, the bezels within the display modules need to be narrow. Therefore, the driver chips in the display modules require COP (Chip On Pi) packaging technology. When using COP packaging, the driver chip is first bonded to a non-display area of ​​the display panel within the display module. Then, the portion of the display panel located within the non-display area is bent to fold the driver chip to the side of the display panel opposite the display surface.

[0004] However, during the splicing of multiple display modules, the non-display areas of the display panel are highly susceptible to impact, causing the signal leads within these areas to break easily. This can lead to display failure. Therefore, spliced ​​screens currently constructed from multiple display modules have relatively low reliability. Summary of the Invention

[0006] On the one hand, a display module is provided, including:

[0007] A support plate, wherein one edge region of the support plate has a bearing groove;

[0008] The display panel is located on the side of the support plate away from the bearing groove.

The first panel portion is disposed on the side of the support plate away from the bearing groove, and the second panel portion is disposed in the bearing groove.

[0009] In addition, a protective bracket is disposed within the bearing groove, with at least a portion of the second panel portion located between the protective bracket and the support plate.

[0016] Optionally, one side of the support plate also has a connecting groove communicating with the bearing groove; the protective bracket includes: a protective body located in the bearing groove, and a connector connected to the protective body, the connector being connected to the support plate in the connecting groove.

[0017] Optionally, the display module further includes a driver chip bonded to the second panel portion, wherein the orthographic projection of the driver chip on one side of the support plate is located within the orthographic projection of the protective body on one side of the support plate.

[0018] Optionally, the side of the support plate includes: a first side having a first opening communicating with the bearing groove; the side of the protective body includes: a second side facing the first opening;

[0019] Wherein, the first side is flush with the second side, or the first side protrudes relative to the second side.

[0020] Optionally, the side of the support plate further includes a plurality of third side surfaces distributed on different sides of the first side surface, wherein the third side surface and the side of the support plate facing away from the first panel have a clearance slope, and the angle between the clearance slope and the third side surface is an obtuse angle.

[0021] Optionally, the display module further includes a protective adhesive layer located on the side of the first panel portion facing away from the support plate, the protective adhesive layer covering the side of the first panel portion facing away from the support plate, and covering the side of the first panel portion that is not connected to the panel bending portion.

[0022] Optionally, the display panel further includes a first cover plate located on the side of the protective adhesive layer opposite to the support plate;

In this way, the protective bracket can protect the side of the second panel portion of the display panel that faces away from the bottom surface of the support groove. During the subsequent splicing of multiple display modules, the side of the second panel portion of each display module that faces away from the bottom surface of the support groove is less likely to collide with adjacent display modules, thus reducing the probability of breakage of the fan-out leads integrated within the second panel portion, and enabling the display module to display images normally. Therefore, the spliced ​​screen obtained by splicing multiple display modules has high reliability. Attached Figure Description

[0054] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0055] Please refer to Figure 1 , Figure 1 This is a partial cross-sectional view of a display module provided by related technologies. The display module may include: a support plate 01, and a display panel 02 located on one side of the support plate 01.

[0056] The display panel 02 may include a flat display section 021 disposed on one side of the support plate 01, and a bent section 022 fixedly connected to one side of the display section 02. A driving component may be attached to the bent section 022, which can control the flat display section 021 to display the corresponding image. The bent section 022 in the display panel 02 can bend the driving component to the side of the support plate 01 away from the flat display section 021, thus ensuring a narrow bezel width for the display module.

[0057] To ensure that the bent portion 022 in the display panel 02 of a certain display module will not interfere with the adjacent display module during the subsequent splicing of multiple display modules, it is necessary to make an oblique cut on the side of the support plate 01 of the display module facing the bent portion 022, so as to form a support slope 01a on the side of the support plate 01 facing the bent portion 022, so that the bent portion 022 in the display panel 02 can fit on the support slope 01a.

[0058] However, in the current display module, the support plate 01 facing the bent portion 022 needs to be completely cut at an angle. That is, please refer to... Figure 2 , Figure 2 yes Figure 1 The bottom view of the support plate in the display module shows that after the support plate 01 is obliquely cut, the length of the resulting support slope 01a is equal to the width of the support plate 01 facing the bend 022. Therefore, if the bend 022 in the display panel 02 is directly attached to this support slope 01a, during the splicing of multiple display modules, the side of the bend 022 in one display module facing away from the support slope 01a is very likely to collide with an adjacent display module. This could cause the signal leads installed in the bend 022 of the display panel 02 to break, potentially leading to display failure in that display module.

[0059] Please refer to Figure 3 , Figure 3 This is a partial cross-sectional view of a display module provided in an embodiment of this application. The display module 000 may include: a support plate 100, a display panel 200, and a protective bracket 300.

[0060] To more clearly see the structure of the support plate 100 in the display module 000, as follows: Figure 4 and Figure 5 As shown, Figure 4 This is a bottom view of a support plate provided in an embodiment of this application. Figure 5 yes Figure 4A cross-sectional view of the support plate at A-A' is shown. The edge region of one side S1 of the support plate 100 in module 000 can have a bearing groove 101. Here, the support plate 100 can be cut using a bevel cutting process to create the bearing groove 101. For example, the side surface of the support plate 100 includes a first side surface M1, from which the support plate 100 can be beveled to create the bearing groove 101, and the bottom surface D of the cut bearing groove 101 is an inclined slope. In this case, the first side surface M1 of the support plate 100 can have a first opening K1 communicating with the bearing groove 101, and one side S1 of the support plate 100 also has a second opening K2 communicating with the bearing groove 101. It should be noted that the bottom surface D of the bearing groove 101 refers to the side of the bearing groove 101 opposite to the second opening K2.

[0061] The display panel 200 in the display module 000 can be located on the side of the support plate 100 opposite to the bearing groove 101. The display panel 200 may include a first panel portion 201 and a second panel portion 202, and a panel bending portion 203 located between the first panel portion 201 and the second panel portion 202, which connects the first panel portion 201 and the second panel portion 202. The first panel portion 201 of the display panel 200 can be disposed on the side S2 of the support plate 100 opposite to the bearing groove 101, and the second panel portion 202 of the display panel 200 can be disposed within the bearing groove 101. For example, the second panel portion 202 can be bonded to the bottom surface D of the bearing groove 101 to be disposed within the bearing groove 101. Here, since the bottom surface D of the support groove 101 is a slope, after the second panel portion 202 in the display panel 200 is attached to the bottom surface D of the support groove 101, it can be ensured that the panel bending portion 203 in each display module 000 will not interfere with the adjacent display module 000 during the splicing of multiple display modules 000.

[0062] It should be noted that, for a clearer view of the structure of the display panel 200, please refer to [reference needed]. Figure 6 , Figure 6 This is a schematic diagram of a display panel unfolded according to an embodiment of this application. The display area 200a of the display panel 200 may be located within the first panel portion 201. In one possible implementation, the display panel 200 may be an OLED flexible display substrate. In this case, the first panel portion 201 may be provided with a plurality of light-emitting devices and a plurality of pixel driving circuits electrically connected to the plurality of light-emitting devices in a one-to-one correspondence.

[0063] The display module 000 may also include a driver chip 400. Here, the driver chip 400 can be bonded to the second panel portion 202 in the display panel 200 by means of bonding. Both the second panel portion 202 and the panel bending portion 203 in the display panel 200 are provided with fan-out leads that are electrically connected to the driver chip 400. The end of the fan-out lead away from the driver chip 400 is used to be electrically connected to the pixel driving circuit provided in the first panel portion 201, so that the driver chip 400 can control the light emission state and light emission brightness of the light-emitting device through the pixel driving circuit, thereby enabling the display area 200a of the first panel portion 201 to display the corresponding display image.

[0064] Here, when it is necessary to assemble the display panel 200 onto the support plate 100, the first panel portion 201 of the display panel 200 can be placed on the side S2 of the support plate 100 facing away from the bearing groove 101. Then, the panel bending portion 203 of the display panel 200 is bent, so that the second panel portion 202 can pass through the first opening K1 and the second opening K2 of the support plate 100 in sequence and enter the bearing groove 101, and fit against the bottom surface D of the bearing groove 101. This allows the driving chip 400 disposed on the second panel portion 202 to also be distributed on the side of the support plate 100 facing away from the first panel portion 201. In this way, the bezel of the display panel 200 can be kept relatively narrow.

[0065] In this application, a portion of the fan-out leads provided within the display panel 200 can be integrated into the display area 200a of the first panel portion 201. This ensures that, in the display panel 200, in the direction of the junction between the panel bending portion 203 and the first panel portion 201, the length L3 of the panel bending portion 203 is less than the length L1 of the first panel portion 201. The length L3 of the panel bending portion 203 is typically equal to the length L2 of the second panel portion 202. Therefore, the length L2 of the second panel portion 202 is less than the length L1 of the first panel portion 201, and the length L2 of the second panel portion 202 is shorter. In this case, the length of the support groove 101 in the support plate 100 for fixing the second panel portion 202 is also shorter, only needing to be slightly greater than the length L2 of the second panel portion 202, to ensure that the second panel portion 202 can smoothly enter the support groove 101. It is not necessary to make a full oblique cut on one side of the support plate 100 facing the panel bending portion 203. Only a partial oblique cut is needed to cut a bearing groove 101 on one side of the support plate 100, which effectively improves the overall manufacturing strength of the support plate 100 and also improves the efficiency of cutting the bearing groove 101 on the support plate 100.

[0066] To more clearly see the mating relationship between the protective bracket 300 and the support plate 100 in the display module 000, please refer to... Figure 7 , Figure 7This is a schematic diagram illustrating the cooperation between a protective bracket and a support plate according to an embodiment of this application. The protective bracket 300 in the display module 000 can be disposed within the bearing groove 101 of the support plate 100, and at least a portion of the second panel portion 202 in the display panel 200 can be located between the protective bracket 300 and the support plate 100. That is, after the second panel portion 202 in the display panel 200 is attached to the bottom surface D of the bearing groove 101, at least a portion of the second panel portion 202 can be located between the protective bracket 300 and the bottom surface D of the bearing groove 101.

[0067] In this configuration, the protective bracket 300 installed within the support groove 101 protects the side of the second panel portion 202 of the display panel 200 that faces away from the bottom surface D of the support groove 101. This ensures that during the subsequent splicing of multiple display modules 000, the side of the second panel portion 202 of each display module 000 facing away from the bottom surface D of the support groove 101 is less likely to collide with adjacent display modules 000. This reduces the probability of breakage of the fan-out leads integrated within the second panel portion 202, thus enabling the display modules 000 to display images normally. Therefore, the splicing screen obtained by splicing multiple display modules 000 has high reliability.

[0068] In summary, the display module provided in this application includes a support plate, a display panel, and a protective bracket. Both the second panel portion of the display panel and the protective bracket can be disposed within the support groove of the support plate, and at least a portion of the second panel portion can be located between the protective bracket and the bottom surface of the support groove. Thus, the protective bracket can protect the side of the second panel portion of the display panel that faces away from the bottom surface of the support groove. During the subsequent splicing of multiple display modules, the side of the second panel portion of each display module that faces away from the bottom surface of the support groove is less likely to collide with adjacent display modules, reducing the probability of breakage of the fan-out leads integrated within the second panel portion, thereby enabling the display module to display images normally. Therefore, the splicing screen obtained by splicing multiple display modules has high reliability.

[0069] In the embodiments of this application, such as Figure 8 and Figure 9 As shown, Figure 8 yes Figure 4 The top view of the support plate is shown. Figure 9 yes Figure 5 The diagram shows a partial enlarged view of the support plate at point B. The edge region of the support plate 100 in the display module 000 facing the first panel portion 201 on its side S2 may have a clearance groove 102 communicating with the support groove 101. A portion of the panel bending portion 203 of the display panel 200 may be located within the clearance groove 102.

[0070] For example, the width d1 of the clearance groove 102 can range from 1 mm to 3 mm. See also... Figure 10 , Figure 10 This is a partial side view of a display module provided in an embodiment of this application. By placing a portion of the panel bending portion 203 of the display panel 200 within the relief groove 102, it can be ensured that the panel bending portion 203, in its bent state, is away from the outermost side of the first panel portion 201 and the second panel portion 202 and will not protrude beyond the first side surface M1 of the support plate 100. Thus, during the subsequent splicing of multiple display modules 000, the first side surface of the support plate 100 can contact adjacent display modules 000, while the panel bending portion 203 will not contact adjacent display modules 000. Therefore, through the protection of the first side surface M1 of the support plate 100, the probability of the panel bending portion 203 colliding with adjacent display modules 000 during splicing can be effectively reduced, thereby ensuring that the signal leads inside the panel bending portion 203 are not easily broken due to collisions.

[0071] In the embodiments of this application, such as Figure 11 and Figure 12 As shown, Figure 11 This is a partial structural diagram of another support plate provided in an embodiment of this application. Figure 12 yes Figure 11 The diagram shows a cross-sectional view of the support plate. The bottom surface D of the support plate 100, which is in contact with the second panel portion 202, may include multiple support ramps D0. Each support ramp D0 may have an acute angle between itself and the side S2 of the support plate 100 facing the first panel portion 201, and the angle between each support ramp D0 and the side S2 of the support plate 100 facing the first panel portion 201 gradually decreases in the direction away from the clearance groove 102. This ensures that the bottom surface D of the support plate 101, which is in contact with the second panel portion 202, has a gradually changing inclination, and the inclination of the bottom surface D of the support plate 101 gradually decreases in the direction away from the clearance groove 102. Thus, after the panel bending portion 203 in the display panel 200 is bent, the second panel portion 202 can be more stably attached to the bottom surface D of the support plate 101.

[0072] Optionally, a first arc-shaped chamfer R1 is formed between the support slope D0 adjacent to the clearance groove 102 and the side S2 of the support plate 100 facing the first panel portion 201. Here, the support slope D0 adjacent to the clearance groove 102 among the multiple support slopes D0 refers to the support slope D0 closest to the clearance groove 102 among the multiple support slopes D0, and no other support slopes D0 are distributed between this support slope D0 and the clearance groove 102. In this case, the first arc-shaped chamfer R1 ensures that the tip formed between the support slope D0 closest to the clearance groove 102 and the side S1 of the support plate 100 facing the first panel portion 201 is relatively rounded, thereby ensuring that this tip will not scratch the panel bending portion 203 in the display panel 200.

[0073] In this embodiment, a second arc-shaped chamfer R2 is provided between two adjacent support slopes D0. The second arc-shaped chamfer R2 ensures that the transition between two adjacent support slopes D0 is relatively smooth, thereby ensuring that the second panel portion 202, which is attached to the bottom surface D of the bearing groove 101, will not be scratched.

[0074] Optionally, the radius of the first arc chamfer R1 and the second arc chamfer R2 in the above embodiments can both be in the range of 0.05 mm to 0.2 mm.

[0075] In the embodiments of this application, such as Figure 13 As shown, Figure 13 yes Figure 11 Another cross-sectional view of the support plate shown indicates that the plurality of support ramps D0 within the bearing groove 101 may include: a first support ramp D01 adjacent to the clearance groove 102, and at least one second support ramp D02 located on the side of the first support ramp D01 facing away from the clearance groove 102. Here, the angle between the second support ramp D02 and the side S2 of the support plate 100 facing the first panel portion 201 needs to be less than or equal to 45°. This ensures that the inclination of the second support ramp D02 within the bearing groove 101 is relatively gentle, resulting in a wider bearing groove 101 and thus a larger area for the second support ramp D02 within the bearing groove 101. Thus, the contact area between the second panel portion 202 and the second support slope D02 in the bearing groove 101 is large, which allows the second panel portion 202 to be firmly attached to the second support slope D02, so as to ensure that the second panel portion 202 will not fall off the second support slope D02 due to the rebound effect of the signal lead inside the panel bending portion 203 after bending.

[0076] It should be noted that the first supporting inclined surface D01 within the support groove 101 primarily serves a transition function, and its width is significantly smaller than that of the second supporting inclined surface D02. Therefore, the orthographic projection of the portion of the second panel 202 used for bonding the driver chip onto the bottom surface D of the support groove 101 needs to be outside the first supporting inclined surface D01, but can be located within the second supporting inclined surface D02. In this way, the wider second supporting inclined surface D02 can effectively support the portion of the second panel 202 used for bonding the driver chip.

[0077] Optional, such as Figure 11 and Figure 14 As shown, Figure 14 This is a bottom view of another support plate provided in the embodiments of this application. One side S1 of the support plate 100 may also have a connecting groove 103 communicating with the bearing groove 101. Here, there may be two connecting grooves 103 provided on one side S1 of the support plate 100. These two connecting grooves 103 may be respectively connected to the bearing groove 101 on both sides of the bearing groove 101.

[0078] like Figure 15 As shown, Figure 15 This application provides another schematic diagram of the cooperation between a support plate and a protective bracket. The protective bracket 300 in the display module 000 may include: a protective body 301 located within a bearing groove 101, and a connector 302 connected to the protective body 301. Here, the connector 302 in the protective bracket 300 can be connected to the support plate 100 within a connecting groove 103. For example, there are various ways in which the connector 302 can be connected to the support plate 100 within the connecting groove 103; for instance, they can be connected by adhesive, magnetic attraction, or screw fastening. This application does not limit the specific method used.

[0079] In this case, after the connector 302 in the protective bracket 300 is connected to the support plate 100 in the connecting groove 103, the protective body 301 in the protective bracket 300 can be located in the bearing groove 101, so that the protective body 301 in the protective bracket 300 can protect the side of the second panel 202 away from the bottom surface D of the bearing groove 101.

[0080] Optionally, the driver chip bonded to the second panel portion 202 in the display module 000 can be covered by the protective body 301 in the protective bracket 300. That is, the orthographic projection of the driver chip on one side S1 of the support plate 100 can be located within the orthographic projection of the protective body 301 on one side S1 of the support plate 100. In this way, the driver chip bonded to the second panel portion 202 can also be protected by the protective body 301, further improving the reliability of the display module 000.

[0081] In the embodiments of this application, such as Figure 15 As shown, the protective component body 301 in the protective bracket 300 can be completely hidden within the bearing groove 101. For example, the side of the protective component body 301 may include a second side M2 ​​distributed towards the first opening K1, wherein the first side M1 of the support plate 100 can be flush with the second side M2 ​​of the protective component body 301, or the first side M1 of the support plate 100 can protrude relative to the second side M2 ​​of the protective component body 301. In this way, it can be ensured that during the subsequent splicing of multiple display modules 000, the first side M1 of the support plate 100, which has higher rigidity, will definitely come into contact with other display modules 000, so as to ensure that the support component body 301 in the protective bracket 300 will not interfere with the splicing process of multiple display modules 000, resulting in higher stability of splicing multiple display modules 000.

[0082] For example, the side S3 of the protective body 301 facing away from the bottom surface D of the bearing groove 101 is flush with the side S1 of the support plate 100, or the side S1 of the support plate 100 protrudes relative to the side S3 of the protective body 301 facing away from the bottom surface D of the bearing groove 101. In this way, it can be ensured that the support body 301 in the protective bracket 300 will not affect the flatness of the back of the display module 000, thus ensuring a high degree of flatness of the back of the display module 000.

[0083] Optional, such as Figure 16 As shown, Figure 16 yes Figure 14 The diagram shows a cross-sectional view of the support plate at point C-C'. The side surface of the support plate 100 may further include multiple third side surfaces M3 distributed on different sides of the first side surface M1. It should be noted that the support plate 100 is typically rectangular in shape. The first side surface M1 of the support plate 100 is the side surface adjacent to the panel bending portion 203 in the display panel 200. This first side surface M1 is also typically the side surface adjacent to the lower frame of the display module 000. All sides of the support plate 100 other than the first side surface M1 are third side surfaces M3. The support plate 100 may have three third side surfaces M3, which are respectively the sides adjacent to the upper frame, left frame, and right frame of the display module 000.

[0084] Here, a clearance slope M4 is provided between the third side M3 of the support plate 100 and the side S1 of the support plate 100 facing away from the first panel portion 201. The angle between the clearance slope M4 and the third side M3 is an obtuse angle. In this case, during the splicing of multiple display modules 000, the clearance slope M4 of the support plate 100 can avoid the probability of interference between the bottom of the support plate 100 and the adjacent display module 000, thereby effectively improving the efficiency of splicing multiple display modules 000.

[0085] In the embodiments of this application, such as Figure 17 As shown, Figure 17 This is a partial cross-sectional view of a display module according to another embodiment of this application. The display module 000 may further include a protective back film 500 located between a first panel portion 201 in the display panel 200 and a support plate 100. Here, the protective back film 500 can be connected to the side of the first panel portion 201 facing the support plate 100 by adhesive bonding, and also connected to the side of the support plate 100 facing the first panel portion 201. The protective back film 500 can protect the back side of the first panel portion 201 in the display panel 200.

[0086] In this application, as Figure 17 As shown, the display module 000 may further include a first cover plate 600 located on the side of the first panel portion 201 in the display panel 200 opposite to the support plate 100. Here, the first cover plate 600 can be bonded to the side of the first panel portion 201 opposite to the support plate 100 by adhesive, and the front of the first panel portion 201 in the display panel 200 can be protected by the first cover plate 600.

[0087] In related technologies, such as Figure 18 As shown, Figure 18 Is adopted Figure 1 The diagram shows a partial view of the spliced ​​screen obtained after the display modules are spliced ​​together. To ensure that the bent portion 022 in the display panel 02 does not collide with adjacent display modules, the side of the first cover plate 03 needs to protrude beyond the outermost edge of the bent portion 022 away from the display portion 021, and the width e of the side of the first cover plate 03 protruding from the outermost edge of the bent portion 022 away from the display portion 021 needs to be larger. In this way, after two adjacent display modules are spliced ​​together, the sides of the two first cover plates 03 in these two adjacent display modules can abut against each other to ensure that the bent portion 022 does not contact the support plate 01 in the adjacent display module. Since the hardness of the first cover plate 03 is usually low, the edge area of ​​the first cover plate 03 is very prone to compression deformation under force after two adjacent display modules are spliced ​​together. Therefore, it is necessary to further widen the width e of the outermost protrusion of the side of the first cover plate 03 relative to the bending portion 022 away from the display portion 021 in order to improve the situation where the local deformation occurs in the edge area of ​​the first cover plate 03, and the bending portion 022 still does not contact the support plate 01 in the adjacent display module. However, when the width e of the outermost protrusion of the side of the first cover plate 03 relative to the bending portion 022 away from the display portion 021 is too wide, the splicing seam width in the splicing screen is too wide, resulting in a poor display effect of the splicing screen.

[0088] Optional, such as Figure 17As shown, the side of the support plate 100 in the display module 000 protrudes beyond the side of the first cover plate 600. That is, the orthographic projection of the first cover plate 600 onto one side of the support plate 100 is entirely within that side of the support plate 100, and there is a certain distance between the boundary of the orthographic projection of the first cover plate 600 onto one side of the support plate 100 and the boundary of that side of the support plate 100. Thus, as... Figure 19 As shown, Figure 19 Is adopted Figure 17 The diagram shows a partial view of the spliced ​​screen obtained after splicing multiple display modules 000. After splicing multiple display modules 000 to form the spliced ​​screen, the sides of the two support plates 100 in two adjacent display modules 000 can contact each other. Since the support plates 100 are usually made of a metal material with high hardness, the probability of the support plates 100 undergoing compression deformation after splicing two adjacent display modules 000 is low. Therefore, the width e' of the side of the support plate 100 protruding relative to the side of the first cover plate 600 does not need to be wide to ensure that the panel bending portion 203 in the display panel 200 does not contact the support plate 100 in the adjacent display module 000. In this way, the splicing gap width in the spliced ​​screen can be narrowed, resulting in a better display effect.

[0089] Furthermore, when the sides of the two support plates 100 in two adjacent display modules 000 within the splicing screen come into contact, the first cover plates 600 in these two display modules 000 do not need to contact each other, and there is a certain gap between them. In this way, it can be ensured that the two first cover plates 600 will not deform due to force, resulting in better flatness of the splicing screen.

[0090] Optional, please refer to Figure 20 , Figure 20 This is a partial cross-sectional view of another display module provided in another embodiment of this application. The display module 000 may further include a protective adhesive layer 700 located on the side of the first panel portion 201 in the display panel 200 facing away from the support plate 100. Here, the protective adhesive layer 700 may cover the side of the first panel portion 201 facing away from the support plate 100, and the protective adhesive layer 700 may cover the side of the first panel portion 201 that is not connected to the panel bending portion 203. For example, the material of the protective adhesive layer 700 may include inorganic waterproof materials such as silicon oxide or aluminum oxide. Furthermore, the protective adhesive layer 700 also has a certain adhesive ability, so the first cover plate 600 in the display module 000 may be located on the side of the protective adhesive layer 700 facing away from the support plate 100, and the first cover plate 600 can be directly bonded to the side of the first panel portion 201 facing away from the support plate 100 through the protective adhesive layer 700.

[0091] In this configuration, the protective adhesive layer 700 can wrap around the first panel portion 201, protecting both the front and sides of the first panel portion 201. Thus, during the splicing of multiple display modules 000, the protective adhesive layer 700 effectively reduces the risk of display failure caused by impacts to the sides of the first panel portion 201.

[0092] Furthermore, the protective adhesive layer 700 also protects the encapsulation layer within the display panel 200, preventing encapsulation failure due to heat during laser cutting of the display panel 200. This further improves the reliability of the display module 000.

[0093] In summary, the display module provided in this application includes a support plate, a display panel, and a protective bracket. Both the second panel portion of the display panel and the protective bracket can be disposed within the support groove of the support plate, and at least a portion of the second panel portion can be located between the protective bracket and the bottom surface of the support groove. Thus, the protective bracket can protect the side of the second panel portion of the display panel that faces away from the bottom surface of the support groove. During the subsequent splicing of multiple display modules, the side of the second panel portion of each display module that faces away from the bottom surface of the support groove is less likely to collide with adjacent display modules, reducing the probability of breakage of the fan-out leads integrated within the second panel portion, thereby enabling the display module to display images normally. Therefore, the splicing screen obtained by splicing multiple display modules has high reliability.

[0094] This application also provides a video wall, such as... Figure 21 As shown, Figure 21 This is a top view of a video wall provided in an embodiment of this application. The video wall may include multiple display modules 000 spliced ​​together, and each display module 000 may be a display module as shown in the above embodiment.

[0095] Optionally, the sides of the two support plates 100 in two adjacent display modules 000 can abut against each other. This ensures a narrow bezel width within the splicing screen, resulting in a better display effect.

[0096] In the embodiments of this application, such as Figure 22 As shown, Figure 22This is a top view of another splicing screen provided in this application embodiment. The splicing screen may further include: at least one second cover plate 001, each second cover plate 001 may correspond to at least two display modules 000, and each second cover plate 001 may cover each corresponding display module 000. Here, the light-emitting side of each display module 000 corresponding to any one of the second cover plates 001 can be attached to the side of the second cover plate 001 facing each display module 000. The second cover plate 001 can not only protect each corresponding display module 000, but also eliminate the splicing error generated by each corresponding display module 000 in the direction perpendicular to the display surface of the splicing screen, so that the light-emitting surfaces of each display module 000 can be in a plane, thereby further improving the display effect of the splicing screen.

[0097] In one possible implementation, such as Figure 22 As shown, the splicing screen includes multiple strip-shaped second cover plates 001, and these second cover plates 001 can be arranged in multiple rows. Each second cover plate 001 can correspond to at least one row of display modules 000. In this way, the splicing error generated by the corresponding at least one row of display modules 000 in the direction perpendicular to the display surface of the splicing screen can be eliminated by the second cover plates 001.

[0098] In another possible implementation, such as Figure 23 As shown, Figure 23 This is a top view of another type of splicing screen provided in this application embodiment. The splicing screen includes a plurality of strip-shaped second cover plates 001, and these second cover plates 001 can be arranged in multiple columns, with each second cover plate 001 corresponding to at least one column of display modules 000. In this way, the splicing error generated by the corresponding at least one column of display modules 000 in the direction perpendicular to the display surface of the splicing screen can be eliminated by the second cover plates 001.

[0099] Of course, in other possible implementations, the splicing screen may also include a single large second cover plate 001, or multiple block-shaped second cover plates 001, with the area of ​​each block-shaped second cover plate 001 being larger than the area of ​​a single display module 000.

[0100] It should be noted that, along the length of the splicing screen, the length of a single second cover plate 001 is an integer multiple of the length of a single display module 000; and along the length of the splicing screen, the width of a single second cover plate 001 is an integer multiple of the width of a single display module 000. This ensures that the seam between two adjacent second cover plates 001 coincides with the seam between two adjacent display modules 000, further improving the display effect of the splicing screen.

[0101] Optionally, the second cover plate 001 in the splicing screen can be a rigid cover plate with high rigidity, such as a glass cover plate. In this way, the second cover plate 001 can better protect each display module 000.

[0102] Optional, such as Figure 24 As shown, Figure 24 This is a cross-sectional view of a second cover plate provided in an embodiment of this application. A surface coating 002 may be provided on the side of the second cover plate 001 facing away from the display module 000. For example, the surface coating 002 may include: an anti-glare coating, an anti-reflective coating, and / or an anti-fingerprint coating, etc. A functional layer 003 may be provided on the side of the second cover plate 001 facing the display module 000. For example, the functional layer 003 may be a touch function layer, thus enabling the splicing screen to have touch functionality.

[0103] It should be noted that the dimensions of layers and regions may be exaggerated in the accompanying drawings for clarity. Furthermore, it is understood that when an element or layer is referred to as being "on" another element or layer, it can be directly on the other element, or there may be intermediate layers. Additionally, it is understood that when an element or layer is referred to as being "below" another element or layer, it can be directly below the other element, or there may be more than one intermediate layer or element. Furthermore, it is also understood that when a layer or element is referred to as being "between" two layers or two elements, it can be the only layer between the two layers or two elements, or there may be more than one intermediate layer or element. Similar reference numerals throughout indicate similar elements.

[0104] In this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The term "multiple" refers to two or more unless otherwise expressly defined.

[0105] The above description is merely an optional embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
