[0065] According to the display module provided by the embodiment of the present application, the support part 200 is arranged in the accommodating cavity 110, the display panel 300 is arranged between the transparent part 101 and the support part 200, the display panel 300 can be fixed on the surface of the support part 200, it is convenient to bend the display panel 300 to the side of the support part 200 away from the transparent part 101, and it is beneficial to realize the bending of the display panel 300 with high precision; at the same time, the shell 100 and the support part 200 are detachably connected, which is convenient for assembly and can meet the disassembly and rework requirements.

[0066] It can be understood that after the display panel 300 is bent, the driving IC (Integrated Circuit) can be arranged on the side of the support part 200 away from the transparent part 101, the support part 200 plays a good supporting role for the driving IC and the bent display panel 300, and the stability of the display module is improved. In addition, under the support of the support part 200, the fracture of the twisted wire can also be prevented.

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

[0068] In one embodiment, referring to Figure 3The structure schematic diagram of the display module is shown. The surface of the support portion 200 towards the transparent portion 101 side includes a curved surface, and the surface of the support portion 200 away from the transparent portion 101 side is a plane. Thus, when the surface of the support portion 200 towards the transparent portion 101 side includes a curved surface, the area of the surface of the support portion 200 towards the transparent portion 101 side is increased, and when the display panel 300 is arranged on the surface of the support portion 200 towards the transparent portion 101 side, the area of the display panel 300 is increased; alternatively, the surface of the support portion 200 away from the transparent portion 101 side includes a plane, and when the surface of the support portion 200 away from the transparent portion 101 side includes a plane, the support driving IC and the display panel 300 after being bent have excellent effects, and the yield of the display panel 300 after being bent is increased.

[0069] In one embodiment, referring to Figure 3 , the surface of the transparent portion 101 towards the support portion 200 side includes a curved surface, and the surface of the transparent portion 101 away from the support portion 200 side includes a curved surface.

[0080] In one embodiment, referring to the structural schematic view of the display module shown in Figure 1 The support part 200 includes an alignment hole 230 for alignment with a positioning mark of the display panel 300.

[0081] In one embodiment, the number of the alignment holes 230 is two, which are located at the fifth end and the sixth end of the support part 200, and the fifth end and the sixth end are oppositely arranged. Exemplarily, the connecting line of the two alignment holes 230 coincides with the center line of the display panel 300 on the side of the support part 200 close to the transparent part 101, and the center line coincides with the symmetry axis of the display panel 300 on the side of the support part 200 close to the transparent part 101.

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

Thus, the setting of the positioning mark 120 hardly affects the normal display of the display panel.

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

In this embodiment, the orthogonal 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 orthogonal projection of the non-display area 320 on the above-mentioned plane.

[0089] Exemplarily, when the positioning mark 120 comprises at least one first groove 123, the positioning mark 120 can be prepared by means of laser. The preparation of the positioning mark 120 by means of laser has the effect of light shielding, so that the display effect of the display module is more excellent.

In this way, the adsorption effect of the second adsorption part 420 is excellent.

[0103] In one embodiment, the first adsorption portion 410 has a thickness less than or equal to 2 mm (e.g., 0.5 mm, 1 mm, 1.5 mm, or 2 mm, etc.); and / or, the second adsorption portion 420 has a thickness less than or equal to 2 mm (e.g., 0.5 mm, 1 mm, 1.5 mm, or 2 mm, etc.).
