[0065] According to the display module provided in the embodiment of the present application, a support portion 200 is arranged in the accommodating cavity 110, and a display panel 300 is arranged between the transparent portion 101 and the support portion 200. The display panel 300 can be fixed on the surface of the support portion 200, so that the display panel 300 can be bent toward the side of the support portion 200 away from the transparent portion 101, which is conducive to achieving high-precision bending of the display panel 300; at the same time, the shell 100 and the support portion 200 are detachably connected, which is convenient for assembly and can meet the needs of disassembly and rework.

[0066] It is understandable that after the display panel 300 is bent, the driver IC (Integrated Circuit) can be arranged on the side of the support portion 200 away from the transparent portion 101, and the support portion 200 plays a good role in supporting the driver IC and the bent display panel 300, thereby improving the stability of the display module. In addition, under the support of the support portion 200, the twist wire can also be prevented from breaking.

[0067] It can be understood that the display panel 300 includes a display area and a non-display area. After a portion of the display panel 300 is bent toward the side of the support portion 200 away from the transparent portion 101, the display area is located on the side of the support portion 200 facing the transparent portion 101, and a portion of the non-display area is used for bending, and the bent portion of the display panel is located on the side of the support portion 200 away from the transparent portion 101.

[0068] In one embodiment, referring to Figure 3In the structural schematic diagram of the display module shown, the surface of the support part 200 facing the transparent part 101 includes a curved surface, and the surface of the support part 200 facing away from the transparent part 101 is a flat surface. Therefore, when the surface of the support part 200 facing the transparent part 101 includes a curved surface, it is beneficial to increase the area of ​​the surface of the support part 200 facing the transparent part 101, and when the display panel 300 is arranged on the side of the support part 200 facing the transparent part 101, it is beneficial to increase the area of ​​the display panel 300; optionally, the surface of the support part 200 facing away from the transparent part 101 includes a flat surface, and when the surface of the support part 200 facing away from the transparent part 101 includes a flat surface, the effect of supporting the driver IC and the display panel 300 after bending is excellent, which is beneficial to improve the yield of the display panel 300 after bending.

[0069] In one embodiment, referring to Figure 3 The surface of the transparent part 101 facing the support part 200 includes a curved surface, and the surface of the transparent part 101 away from the support part 200 includes a curved surface. It can be understood that the surface of the transparent part 101 facing the support part 200 has the same structure as the surface of the transparent part 101 away from the support part 200.

[0070] It can be understood that the surface of the transparent part 101 facing the support part 200 is a curved surface, and the surface of the support part 200 facing the transparent part 101 is a curved surface, and the two curved surfaces match. Exemplarily, the surface of the transparent part 101 facing the support part 200 is a convex surface, and the surface of the support part 200 facing the transparent part 101 is a concave surface; Exemplarily, the surface of the transparent part 101 facing the support part 200 is a concave surface, and the surface of the support part 200 facing the transparent part 101 is a convex surface.

[0071] In one embodiment, on a plane perpendicular to the thickness direction of the support portion 200, the orthographic projection of the transparent portion 101 on the plane covers the orthographic projection of the display panel 300 on the plane facing the transparent portion 101. Thus, the display module has an excellent display effect.

[0072] In one embodiment, the detachable connection between the support portion 200 and the housing 100 includes a snap connection. Thus, the detachable connection is simple, easy to implement, and easy to disassemble.

[0073] In one embodiment, the snap-fit ​​connection includes at least one of a cantilever snap-fit ​​connection, a ring snap-fit ​​connection, and a ball-type snap-fit ​​connection.

[0074] Exemplarily, the material of the support portion 200 includes but is not limited to at least one of polyphenylene sulfide (PPS), polycarbonate (PC), acrylonitrile-butadiene-styrene copolymer (ABS) and glass fiber (GF); exemplary, the material of the support portion 200 includes high modulus PC composed of PC and ABS, or, the material of the support portion 200 includes high modulus PC composed of PC and GF.

[0075] In one embodiment, referring to Figure 1 In the structural schematic diagram of the display module shown, the housing 100 includes a first sub-housing 102 and a second sub-housing 103, the first end of the first sub-housing 102 is rotatably connected to the third end of the second sub-housing 103, the support portion 200 is detachably connected to the first sub-housing 102, and the first sub-housing 102 includes a transparent portion 101. Thus, the support portion 200 is easily assembled.

[0076] It can be understood that the first sub-housing 102 and the second sub-housing 103 enclose a receiving cavity 110 .

[0077] In one embodiment, referring to Figure 1 In the structural diagram of the display module shown in FIG. 1 , the first end of the first sub-housing 102 includes a limiting groove 1023, and the fifth end of the support portion 200 includes a protrusion 211, which is arranged corresponding to the limiting groove 1023. Thus, the support portion 200 and the first sub-housing 102 can be firmly connected together to improve the stability of the display module.

[0078] In one embodiment, referring to Figure 4 or Figure 5 In the structural diagram of the buckle connection between the housing and the support part shown in the figure, the second end of the first sub-housing 102 includes a buckle 1024, and the sixth end of the support part 200 includes a buckle 221, and the buckle 221 is arranged corresponding to the buckle 1024; the first end is arranged opposite to the second end, and the fifth end is arranged opposite to the sixth end. Therefore, the buckle 221 and the buckle 1024 have a better matching effect, the connection is more stable, and the stability of the display module is improved.

[0079] Exemplarily, the principle of the buckle 221 and the slot 1024 cooperating to achieve the buckle connection is prior art and will not be elaborated on here.

[0080] In one embodiment, referring to Figure 1 In the structural diagram of the display module shown, the support portion 200 includes an alignment hole 230, and the alignment hole 230 is used to align with the positioning mark of the display panel 300. This facilitates the realization of high-precision bending of the display panel 300.

[0081] In one embodiment, there are two alignment holes 230, which are respectively located at the fifth end and the sixth end of the support portion 200, and the fifth end and the sixth end are arranged opposite to each other. Exemplarily, the connection line of the two alignment holes 230 coincides with the center line of the display panel 300 on the side of the support portion 200 close to the transparent portion 101, and the center line coincides with the symmetry axis of the display panel 300 on the side of the support portion 200 close to the transparent portion 101. Therefore, the alignment holes 230 can be used as positioning marks when the display panel 300 is bent, meeting the folding positioning requirements of the display panel 300.

[0082] Exemplarily, the alignment holes 230 are located on two opposite sides of the display panel 300 .

[0083] In one embodiment, the size of the alignment hole 230 is greater than or equal to 0.5 mm, for example, it can be 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm or 1 mm, etc. It should be noted that the size of the alignment hole 230 refers to the maximum distance between any two points in the orthographic projection of the alignment hole 230 on a plane perpendicular to the thickness direction of the support portion 200.

[0084] In one embodiment, the alignment hole 230 includes at least one of a round hole, a square hole, and a bar-shaped hole.

[0085] In one embodiment, referring to Figure 6 The partial enlarged structural diagram of the display module at A shown in FIG. Figure 7 In the structural schematic diagram of the display module shown, the housing 100 includes a positioning mark 120, which is located on the transparent part 101, and the display panel 300 has a display area and a non-display area, and the non-display area surrounds at least part of the display area. The edge of the orthographic projection of the positioning mark 120 on a plane perpendicular to the thickness direction of the support part 200 is located in the orthographic projection of the non-display area on the plane. Therefore, the setting of the positioning mark 120 will hardly affect the normal display of the display panel.

[0086] In one embodiment, the positioning mark 120 includes a boss 121 located on the side of the shell 100 away from the support portion 200, and the orthographic projection of the display area 310 on a plane perpendicular to the thickness direction of the support portion 200 is located within the orthographic projection range of the boss 121 on the above plane.

[0087] In one embodiment, the positioning mark 120 further includes a light shielding portion, which is located at least partially around the boss 121; preferably, the positioning mark 120 further includes a second groove 122, which is located at least partially around the boss 121, and the light shielding portion is located in the second groove 122. The setting of the light shielding portion can achieve a light shielding effect, so that the display effect of the display module is more excellent. Exemplarily, the light shielding portion includes ink and / or a laser structure.

[0088] In one embodiment, the positioning mark 120 includes a plurality of through holes; or, referring to Figure 8 In the structural diagram of the display module shown, the positioning mark 120 includes at least one first groove 123. In this embodiment, the orthographic projection of the through hole or the first groove 123 on a plane perpendicular to the thickness direction of the support portion 200 is located within the orthographic projection of the non-display area 320 on the above plane.

[0089] For example, when the positioning mark 120 includes at least one first groove 123, the positioning mark 120 can be prepared by laser. The laser method for preparing the positioning mark 120 has a light shielding effect, so that the display effect of the display module is more excellent.

[0090] In one embodiment, the orthographic projection of the first groove 123 on a plane perpendicular to the thickness direction of the support portion 200 includes at least one of a circle, a square, a square shape, and a ring shape.

[0091] In one embodiment, the through hole includes at least one of a circular hole, a square hole, and an L-shaped hole.

[0092] For example, when assembling the display module, the display panel needs to be placed on one side of the first sub-housing 102 , and the transparent portion 101 needs to be arranged corresponding to the display area 310 of the display panel 300 , and the positioning mark 120 needs to be used for positioning to achieve precise alignment.

[0093] The second aspect of the present application provides a method for assembling a display module, referring to Fig. 9 The flowchart of the assembly method of the display module shown is a schematic diagram, and the assembly method includes the following steps.

[0094] S100: placing a display panel in a receiving cavity surrounded by a housing, wherein the display panel is arranged corresponding to a transparent portion of the housing.

[0095] It should be noted that the display panel and the housing are consistent with the above description and will not be elaborated herein.

[0096] In one embodiment, referring to Figure 1 or Figure 2 , the display module also includes: a first adsorption portion 410, located at a side of the second end of the first sub-shell 102 away from the first end, the first end and the second end are arranged opposite to each other; a second adsorption portion 420, located at a side of the fourth end of the second sub-shell 103 away from the third end, the fourth end and the third end are arranged opposite to each other. Thus, the first adsorption portion 410 and the second adsorption portion 420 are used for adsorption turnover to solve the problem of being unable to adsorb when transporting or assembling products. Exemplarily, after assembling the display module, the first adsorption portion 410 and the second adsorption portion 420 can be removed.

[0097] For example, refer to Figure 1 The housing 100 includes a first sub-housing 102 and a second sub-housing 103 , the first end 1021 of the first sub-housing 102 is rotatably connected to the third end 1031 of the second sub-housing 103 , the support portion 200 is detachably connected to the first sub-housing 102 , and the first sub-housing 102 has a transparent portion 101 .

[0098] In one embodiment, before the step of placing the display panel in the accommodating cavity surrounded by the housing, the method further includes: fixing the first adsorption portion and the second adsorption portion on the carrier respectively. Thus, it is convenient to fix the housing on the carrier, which is beneficial to the subsequent operation steps. Optionally, the first adsorption portion and the second adsorption portion can be fixed on the carrier by adsorption.

[0099] In one embodiment, the connection between the first adsorption part 410 and the first sub-shell 102 includes a thin-wall connection; and / or the connection between the second adsorption part 420 and the second sub-shell 103 includes a thin-wall connection. Thus, the first adsorption part 410 and the second adsorption part 420 are easily removed.

[0100] It should be noted that the thin-wall connection refers to a structure composed of a thin plate and a reinforcing member. In the embodiment of the present application, the thin-wall connection between the first adsorption portion 410 and the first sub-shell 102 means that: the first adsorption portion 410 and the first sub-shell 102 are connected at a through hole or a gap, and the thickness of the first adsorption portion 410 is relatively thin; the thin-wall connection between the second adsorption portion 420 and the second sub-shell 103 means that: the second adsorption portion 420 and the second sub-shell 103 are connected at a through hole or a gap, and the thickness of the second adsorption portion 420 is relatively thin.

[0101] In one embodiment, in the direction from the first end to the second end, the length of the first adsorption portion 410 is less than or equal to 10 mm (for example, it may be 5 mm, 6 mm, 7 mm, 8 mm, 9 mm or 10 mm, etc.), and in the direction perpendicular to the first end and pointing to the second end, the width of the first adsorption portion 410 is less than or equal to 10 mm (for example, it may be 5 mm, 6 mm, 7 mm, 8 mm, 9 mm or 10 mm, etc.). Thus, the first adsorption portion 410 has an excellent adsorption effect.

[0102] In one embodiment, in the direction from the third end 1031 to the fourth end 1032, the length of the second adsorption portion 420 is less than or equal to 10 mm (for example, it may be 5 mm, 6 mm, 7 mm, 8 mm, 9 mm or 10 mm, etc.), and in the direction perpendicular to the third end 1031 and pointing to the fourth end 1032, the width of the second adsorption portion 420 is less than or equal to 10 mm (for example, it may be 5 mm, 6 mm, 7 mm, 8 mm, 9 mm or 10 mm, etc.). Thus, the adsorption effect of the second adsorption portion 420 is excellent.

[0103] In one embodiment, the thickness of the first adsorption portion 410 is less than or equal to 2 mm (for example, it can be 0.5 mm, 1 mm, 1.5 mm or 2 mm, etc.); and / or the thickness of the second adsorption portion 420 is less than or equal to 2 mm (for example, it can be 0.5 mm, 1 mm, 1.5 mm or 2 mm, etc.). Thus, the first adsorption portion 410 and the second adsorption portion 420 can be connected to the support portion 200 more stably.
