[0030] The embodiments of the present utility model provide a back plate and a display module. The following are detailed descriptions. It should be noted that the description order of the following embodiments is not intended to limit the preferred order of the embodiments.

[0031] Please combine Figure 1 and Figure 2 ;in, Figure 1 A first top view schematic diagram of a back plate provided by an embodiment of the utility model; Figure 2 for Figure 1 Schematic diagram of the cross section at A-Aˋ in the figure.

[0032] The present embodiment provides a backplane 1, which includes a backplane body 11, a reinforcement structure 12 and a wire pressing structure 13; the backplane body 11 includes a first surface 111, and the reinforcement structure 12 is arranged on the first surface 111 of the backplane body 11; the wire pressing structure 13 is arranged on the first surface 111 of the backplane body 11, and the wire pressing structure 13 is located at the periphery of the reinforcement structure 12; wherein, there is a gap between the wire pressing structure 13 and the reinforcement structure 12.

[0033] Specifically, the height L2 of the wire pressing structure 13 is smaller than the height L1 of the reinforcing structure 12. Figure 2 In the cross-sectional view of the back panel shown, the reinforcing structure 12 includes a first protrusion 12A formed on the first surface 111, and the wire pressing structure 13 includes a second protrusion 13A formed on the first surface 111, wherein there is a gap between the first protrusion 12A and the second protrusion 13A, so that the length of the side wall of the reinforcing structure 12 is increased, thereby improving the rigidity of the back panel 1.

[0034] In one embodiment, the width D1 of the second protrusion is between 2 mm and 7 mm; specifically, the pressing line structure 13 includes at least two pressing lines 131 arranged at intervals, specifically, the pressing line structure 13 includes a first pressing line 1311 and a second pressing line 1312, the first pressing line 1311 surrounds the periphery of the reinforcing structure 12, and the second pressing line 1312 surrounds the periphery of the first pressing line 1311; wherein the second pressing line 1312 is adjacent to the first pressing line 1311, and the sum of the widths of the second pressing line 1312 and the first pressing line 1311 is greater than or equal to 2 mm and less than or equal to 7 mm.

[0035] In one embodiment, the first protrusion 12A includes a top surface 121A and side walls 122A located on both sides of the top surface 121A, and a preset angle α is formed between the side walls 122A and the top surface 121A; wherein the preset angle α is greater than 90 degrees and less than 180 degrees, so that by setting the preset angle α to be an obtuse angle, when the first protrusion 12A is manufactured on the back panel body 11 by a stamping process, it is convenient to remove the workpiece, reduce the difficulty of demolding, and thus improve the manufacturing efficiency.

[0036] It should be noted that in the existing backplane manufacturing process, in order to improve the rigidity of the backplane itself, reinforcing ribs need to be provided on the backplane body; currently, a stamping process is usually adopted to manufacture reinforcing ribs with a raised / recessed structure on a flat backplane body; however, in the process of manufacturing the reinforcing ribs, a large stress is generated on the backplane body, which can easily cause deformation at the connection between the processed backplane body and the reinforcing ribs, thereby causing the problem of poor flatness of the backplane body.

[0037] In one embodiment, from a top view of the back plate 1, the reinforcement structure 12 includes a long side 12A1 and a short side 12A2 connected to each other, the extension direction of the long side 12A1 is parallel to the first direction X, the extension direction of the short side 12A2 is parallel to the second direction Y, and the angle between the first direction X and the second direction Y is greater than 0 and less than or equal to 90 degrees; wherein the length of the long side 12A1 is greater than the length of the short side 12A2, and the extension direction of the second protrusion 13A is parallel to the first direction X.

[0038] It should be noted that, in this embodiment, the technical solution of the present utility model is illustrated by taking the first direction as the X direction, the second direction as the Y direction, and the angle between the first direction X and the second direction Y as 90 degrees.

[0039] Furthermore, the wire pressing structure 13 includes a first section 13A1, which is arranged corresponding to the long side 12A1 of the reinforcement structure 12, and the first section 13A1 includes alternately connected first arc portions 131A and second arc portions 132A, and the first arc portions 131A and the second arc portions 132A are tangent at the connection.

[0040] Specifically, in the top view of the back plate 1, along the first direction X, the first section 13A1 includes a plurality of first arc portions 131A and a plurality of second arc portions 132A that are alternately connected, the first arc portion 131A is tangent to the second arc portion 132A at the connection, one of the first arc portion 131A and the second arc portion 132A protrudes in the direction away from the long side 12A1 of the reinforcement structure 12, and the other of the first arc portion 131A and the second arc portion 132A protrudes in the direction close to the long side 12A1 of the reinforcement structure 12.

[0041] It can be understood that in this embodiment, when the back panel 1 is viewed from a top view, the reinforcement structure 12 includes a long side 12A1 and a short side 12A2 connected to each other, and the wire pressing structure 13 includes a first section 13A1, and the first section 13A1 includes a first arc portion 131A and a second arc portion 132A that are alternately connected, and the first arc portion 131A and the second arc portion 132A are tangent to each other at the connection, thereby effectively reducing the influence of the large stress generated on the back panel body 11 during the production process of the existing reinforcement ribs, which easily causes the connection between the processed back panel body 11 and the reinforcement ribs to deform, thereby improving the flatness of the back panel 1 body and ensuring the flatness between the film layers during the subsequent display module assembly process; and, the first section 13A1 is arranged corresponding to the long side 12A1 of the reinforcement structure 12, so that the extension direction of the wire pressing structure 13 is consistent with the extension direction of the reinforcement structure 12, further improving the flatness of the back panel 1 body.

[0042] Furthermore, in one embodiment, the wire pressing structure 13 further includes a connecting portion 13A2, and the connecting portion 13A2 is arranged corresponding to the short side 12A2 of the reinforcing structure 12, and two ends of the connecting portion 13A2 are respectively connected to the two first sections 13A1.

[0043] Specifically, in the top-down view of the back panel 1, along the second direction Y, one end of the connecting portion 13A2 is connected to the first arc portion 131A, and the other end of the connecting portion 13A2 is connected to the second arc portion 132A; wherein, the connecting portion 13A2 is an arc, and the bending directions of the arc 13A2 and the short side 12A2 of the reinforcing structure 12 are consistent, thereby extending the length of the wire pressing structure 13, that is, the length of the reinforcing rib, thereby increasing the overall strength and rigidity of the back panel 1.

[0044] Further, the curvature of the second arc portion 132A is equal to the curvature of the first arc portion 131A, and the curvature of the connecting portion 13A2 is greater than the curvature of the first arc portion 131A; wherein, the first arc portion 131A and the second arc portion 132A are tangent at the connection, the connecting portion 13A2 and the first arc portion 131A are tangent at the connection, and the connecting portion 13A2 and the second arc portion 132A are tangent at the connection.

[0045] Specifically, in the top view of the back panel 1 body, the first arc portion 131A protrudes in the direction away from the long side 12A1 of the reinforcement structure 12, and the distance between the first arc portion 131A and the long side 12A1 of the reinforcement structure 12 is equal to the distance between the connecting portion 13A2 and the short side 12A2 of the reinforcement structure 12, so that the multiple first arc portions 131A, the multiple second arc portions 132A and the connecting portion 13A2 are evenly distributed around the reinforcement structure 12 to improve the flatness of the back panel 1.

[0046] It can be understood that, in this embodiment, the first arc portion 131A and the second arc portion 132A are tangent at the connection, the connecting portion 13A2 and the first arc portion 131A are tangent at the connection, and the connecting portion 13A2 and the second arc portion 132A are tangent at the connection, that is, the first arc portion 131A and the second arc portion 132A are smoothly transitioned, the first arc portion 131A and the connecting portion 13A2 are smoothly transitioned, and the second arc portion 132A and the connecting portion 13A2 are smoothly transitioned, so that when the back plate 1 is subjected to force, the first arc portion 131A, the second arc portion 132A and the connecting portion 13A2 can disperse the concentrated stress, thereby avoiding stress concentration and affecting the flatness of the back plate 1.

[0047] Please combine Figure 3 and Figure 4 ;in, Figure 3 A second top view schematic diagram of the back plate provided by an embodiment of the utility model; Figure 4 for Figure 3 Schematic diagram of the cross section at B-Bˋ in the figure.
