Description

Technical Field

[0001] This invention relates to the field of display device technology, and in particular to a display module assembly and a bracket for fixing the display module. Background Technology

[0002] Flexible panels, such as flexible organic light-emitting diodes (OLEDs), offer numerous advantages over traditional liquid crystal displays, including bendability, active light emission, high contrast, thinness, and fast response. Consequently, flexible display technology has garnered increasing attention in recent years, with ever-higher performance requirements, leading to research into technologies such as narrow bezels and full-screen displays.

[0003] Generally speaking, flexible panels mainly include a display area, a bonding area, and a bending area. The bending area is mainly used to lead the data signal lines of the display area to the bonding area for electrical connection with the driver chip, so that the driver chip can be bent to the back of the display area.

[0004] Currently, the bending area of ​​flexible display modules often breaks due to pressure or impacts caused by poor impact resistance during module manufacturing, packaging, logistics, and assembly. This results in frequent display abnormalities and affects product yield. Summary of the Invention

[0005] This invention provides a display module assembly and a bracket for fixing the display module, thereby addressing the shortcomings of related technologies.

[0006] To achieve the above objectives, a first aspect of the present invention provides a bracket for fixing a display module, comprising:

[0007] Support plate;

[0008] A first clamping plate is connected to the first end of the receiving plate;

[0009] A second clamping plate is connected to a second end of the receiving plate, the second end being disposed opposite to the first end; the first clamping plate and the second clamping plate are adapted to clamp two opposite sides of the glass cover of the display module to position the display module, and the space between the second clamping plate and the receiving plate is adapted to accommodate a bending area of ​​the display module; and

[0010] A support protrusion is connected to the receiving plate, and the support protrusion is adapted to abut against the non-light-emitting side of the display module to limit the display module in the normal direction of the display module.

[0011] Optionally, the clamping surface of the first clamping plate and / or the clamping surface of the second clamping plate are provided with a first elastic element.

[0012] Optionally, the first elastic element is at least one of a rubber pad, a foam pad, and a silicone pad.

[0013] Optionally, the clamping surface of the first clamping plate and / or the clamping surface of the second clamping plate has a plurality of first protrusions, the extending direction of the first protrusions being parallel to the extending direction of the side.

[0014] Optionally, the clamping surface of the first clamping plate and / or the clamping surface of the second clamping plate has a plurality of second protrusions, each second protrusion having a plurality of recessed areas spaced apart, the extending direction of the second protrusions being perpendicular to the extending direction of the side, and the recessed areas on each second protrusion being distributed along multiple rows, each row being parallel to the extending direction of the side.

[0015] Optionally, the first clamping plate includes a first free end and a first fixed end disposed opposite to each other, the first free end being outwardly flared relative to the first fixed end; and / or the second clamping plate includes a second free end and a second fixed end disposed opposite to each other, the second free end being outwardly flared relative to the second fixed end.

[0016] Optionally, the angle between the normal plane of the plane where the first clamping plate is located and the plane where the receiving plate is located is in the range of 7 degrees to 10 degrees; and / or the angle between the normal plane of the plane where the second clamping plate is located and the plane where the receiving plate is located is in the range of 7 degrees to 10 degrees.

[0017] Optionally, the thickness of the first free end of the first clamping plate is less than the thickness of the first fixed end; and / or the thickness of the second free end of the second clamping plate is less than the thickness of the second fixed end.

[0018] Optionally, the dimension of the first clamping plate in the extension direction of the side is smaller than the dimension of the second clamping plate in the extension direction of the side.

[0019] Optionally, the top surface of the support protrusion is provided with a second elastic element.

[0020] Optionally, the second elastic element is at least one of a rubber pad, a foam pad, and a silicone pad.

[0021] Optionally, the supporting protrusion is a supporting column, and the supporting column has a hollow structure.

[0022] Optionally, the bracket further includes: a positioning plate connected to the third end of the receiving plate; the positioning plate is adapted to abut against the top or bottom edge of the glass cover of the display module to pre-position the display module in the extending direction of the side.

[0023] A second aspect of the present invention provides a display module assembly, comprising:

[0024] A display module, comprising a light-emitting side and a non-light-emitting side, wherein the light-emitting side is provided with a glass cover plate; and

[0025] The bracket for fixing the display module as described in any of the above.

[0026] Optionally, the display module is a curved screen or a flat screen.

[0027] As the background technology indicates, the bending area of ​​flexible display modules often breaks due to pressure or impacts because of poor impact resistance. To address this issue, several solutions have emerged. For example, the injection-molded part is fixed to the display module using double-sided foam adhesive, covering the bending area of ​​the display module on one side. However, the inventors' analysis shows that in small-sized display modules, the adhesive area is limited; or when the display module lacks a flat area, adhesive bonding often results in problems such as the injection-molded part shaking, uneven adhesion, and partial detachment. Residual adhesive also appears on the display module surface, reducing yield.

[0028] Based on the above analysis, in the above embodiments of the present invention, a bracket for fixing a display module is provided. A first clamping plate and a second clamping plate clamp two opposite sides of the glass cover plate of the display module to position the display module. The space between the second clamping plate and the receiving plate is adapted to accommodate the bending area of ​​the display module. During assembly, the support protrusion abuts against the non-light-emitting side of the display module, which can limit the display module in the normal direction of the display module, preventing excessive pressure on the display module from causing the bending area to collide with the receiving plate. Therefore, on the one hand, the display module can be firmly fixed in three dimensions, avoiding impact on the bending area of ​​the display module; on the other hand, the bracket is reusable, convenient, and does not introduce glue onto the display module, avoiding adhesive residue.

The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention.

Figure 3 This is a schematic diagram of the display module components. Figure 4 yes Figure 3 A schematic diagram of the display module in the image.

[0052] Reference Figures 1 to 4 As shown, the bracket 11 for fixing the display module includes:

[0053] 110 bearing plate;

[0054] The first clamping plate 111 is connected to the first end of the receiving plate 110;

[0055] The second clamping plate 112 is connected to the second end of the receiving plate 110, and the second end is disposed opposite to the first end; the first clamping plate 111 and the second clamping plate 112 are adapted to clamp the two opposite sides 101a and 101b of the glass cover plate 101 of the display module 10 to position the display module 10; the second clamping plate 112 and the receiving plate 110 are adapted to accommodate the bending area 102 of the display module 10; and

[0056] A support protrusion 113 is connected to a receiving plate 110. The support protrusion 113 is adapted to abut against the non-light-emitting side 10b of the display module 10 to limit the display module 10 in the normal direction of the display module 10.

[0057] Reference Figures 2 to 4 As shown, module component 1 includes:

[0058] Display module 10, comprising a light-emitting side 10a and a non-light-emitting side 10b, wherein the light-emitting side 10a is provided with a glass cover plate 101; and

[0059] The bracket 11 mentioned above is used to fix the display module 10.

[0060] Reference Figure 4 As shown, the display module 10 may include a back panel. The back panel includes a display area and a bending area 102. A display structure is disposed on the display area, and the display area is connected to the flexible circuit board 103 through the bending area 102 to provide driving signals to the display structure.

[0061] The display module 10 also includes a glass cover plate 101 to protect the display structure from scratches. In this embodiment, the display module 10 is generally rectangular, so the glass cover plate 101 may include opposite sides 101a and 101b, as well as a top edge 101c and a bottom edge 101d. In this embodiment, the side of the glass cover plate 101 closest to the bending area 102 is defined as side edge 101a.

[0062] In other embodiments, the display module 10 may also be circular or other shapes.

[0063] In this embodiment, the display module 10 is a curved screen; in other embodiments, the display module 10 may also be a flat screen.

[0064] In this embodiment, refer to Figure 1 and Figure 2 As shown, a first elastic element 12 is bonded to the clamping surfaces of the first clamping plate 111 and the second clamping plate 112. The first elastic element 12 can act as a buffer to prevent ink from dripping from the sides 101a and 101b of the glass cover plate 101. The ink can prevent light leakage from the sides 101a and 101b of the glass cover plate 101.

[0065] The first elastic element 12 can be at least one of a rubber pad, foam pad, and silicone pad. After the bracket 11 is assembled with the display module 10, the first elastic element 12 is in a compressed state. Preferably, the compression is 50% or more.

[0066] In other embodiments, the first elastic member 12 may also be selected from the clamping surface of the first clamping plate 111 and the clamping surface of the second clamping plate 112.

[0067] In this embodiment, the support 11 can be integrally molded, for example, by injection molding.

[0068] Reference Figure 1 As shown, in this embodiment, the first clamping plate 111 includes a first free end 111a and a first fixed end 111b disposed opposite to each other, with the first free end 111a extending outward relative to the first fixed end 111b; the second clamping plate 112 includes a second free end 112a and a second fixed end 112b disposed opposite to each other, with the second free end 112a extending outward relative to the second fixed end 112b.

[0069] Preferably, the angle α between the normal plane of the plane containing the first clamping plate 111 and the plane containing the receiving plate 110 ranges from 7 degrees to 10 degrees; the angle α between the normal plane of the plane containing the second clamping plate 112 and the plane containing the receiving plate 110 also ranges from 7 degrees to 10 degrees. In other words, the outward angle of the first clamping plate 111 and the second clamping plate 112 ranges from 7 degrees to 10 degrees. This outward expansion facilitates both the demolding process during injection molding and the assembly of the display module 10.

[0070] The thickness of the first free end 111a of the first clamping plate 111 can be less than the thickness of the first fixed end 111b; the thickness of the second free end 112a of the second clamping plate 112 can be less than the thickness of the second fixed end 112b. The smaller thickness of the free end facilitates the opening and assembly of the display module 10, while the larger thickness of the fixed end prevents deformation and loosening during clamping of the display module 10, thus preventing the display module 10 from falling off.

[0071] In other embodiments, either the first clamping plate 111 or the second clamping plate 112 can be extended outwards.

[0072] To prevent excessive deformation of the bracket 11 after assembly with the display module 10, the thickness of the first clamping plate 111, the second clamping plate 112, and the receiving plate 110 can be greater than or equal to 1.5mm.

[0073] In this embodiment, the dimension of the first clamping plate 111 in the extension direction of the side 101a is smaller than the dimension of the second clamping plate 112 in the extension direction of the side 101b, which helps to reduce the weight of the bracket 11.

[0074] The support protrusion 113 prevents the display module 10 from being over-pressed during assembly of the bracket 11 and the display module 10, thus preventing the bending area 102 from colliding with the receiving plate 110. Additionally, the support protrusion 113 prevents the middle of the receiving plate 110 from collapsing due to excessive span between the first clamping plate 111 and the second clamping plate 112. One or more support protrusions 113 may be present.

[0075] In this embodiment, the support protrusion 113 abuts against the flexible circuit board 103.

[0076] A second elastic element 13 may be bonded to the top surface of the supporting protrusion 113. The second elastic element 13 may be at least one of a rubber pad, foam adhesive, and silicone pad.

[0077] In this embodiment, the support protrusion 113 is a support column to avoid excessive size and interference with components on the non-light-emitting side 10b of the display module 10. The support column can be a hollow structure to reduce the weight of the bracket 11.

[0078] To avoid over- or under-pressure conditions on the bracket 11 during assembly, the sum of the height of the supporting protrusion 113 and the thickness of the display module 10 is equal to the distance between the free ends of the receiving plate 110 and the first clamping plate 111 (or the second clamping plate 112). In other words, the total height of the bracket 11 is designed to be level with the light-emitting surface of the glass cover plate 101 of the display module 10. After the bracket 11 is attached to the display module 10, it can be manually pressed down again to ensure a secure assembly.

[0079] In this embodiment, refer to Figures 1 to 3As shown, the bracket 11 also includes: a positioning plate 114 connected to the third end of the receiving plate 110; the positioning plate 114 is adapted to abut against the top edge 101c of the glass cover plate 101 of the display module 10 to pre-position the display module 10 in the extending direction of the sides 101a, 101b.

[0080] The third end of the receiving plate 110 is different from the first and second ends. The positioning plate 114 can play an auxiliary role in fitting and aligning during the process of fixing the display module 10 to the bracket 11.

[0081] In other embodiments, the positioning plate 114 may also be adapted to abut against the bottom edge 101d of the glass cover plate 101 of the display module 10.

[0082] The first elastic element 12 can also be bonded to the abutting side of the positioning plate 114.

[0083] The bracket 11 used to fix the display module in this embodiment can firmly fix the display module 10 in three dimensions, avoiding impact on the bending area 102 of the display module 10; on the other hand, the bracket 11 is reusable, easy to assemble, and does not introduce glue into the display module 10, thus avoiding adhesive residue.

[0084] Figure 5 This is a schematic diagram of the structure of the bracket for fixing the display module according to the second embodiment of the present invention.

[0085] Reference Figure 5 As shown, the difference between the display module assembly and the bracket for fixing the display module in this embodiment 2 and the display module assembly and the bracket for fixing the display module in embodiment 1 is that the clamping surface of the first clamping plate 111 and the clamping surface of the second clamping plate 112 have a plurality of first protrusions 14, and the extending direction of the first protrusions 14 is parallel to the extending direction of the sides 101a and 101b.

[0086] The first protrusion 14 can improve the positioning effect of the bracket 11 on the display module 10 in the normal direction.

[0087] The first protrusion 14 can be set on either the clamping surface of the first clamping plate 111 or the clamping surface of the second clamping plate 112.

[0089] Reference Figure 5As shown, the display module assembly and the bracket for fixing the display module in this embodiment 3 differ from the display module assembly and the bracket for fixing the display module in embodiments 1 and 2 in that: the clamping surface of the first clamping plate 111 and the clamping surface of the second clamping plate 112 have a plurality of second protrusions 15, each second protrusion 15 has a plurality of recessed areas 15a spaced apart, the extension direction of the second protrusion 15 is perpendicular to the extension direction of the sides 101a and 101b, and the recessed areas 15a on each second protrusion 15 are distributed along multiple rows, each row being parallel to the extension direction of the sides 101a and 101b.

[0090] The recessed area 15a on the second protrusion 15 can improve the positioning effect of the bracket 11 on the display module 10 in the normal direction.

[0091] The second protrusion 15 can be set on either the clamping surface of the first clamping plate 111 or the clamping surface of the second clamping plate 112.

[0092] The display device used in the above-mentioned display module component 1 can be any product or component with display function, such as electronic paper, mobile phone, tablet computer, television, laptop computer, digital photo frame, navigator, wearable device, etc.
