The housing body 111 can have a first mounting surface 1111 along the thickness direction of the housing 11 (for example, the direction indicated by the x-axis in FIG. 1).

[0051] In some examples, the display module 10 can include a glass substrate PCB 12. The glass substrate PCB 12 can be mounted on the first mounting surface 1111. The glass substrate PCB 12 refers to a printed circuit board that uses glass material as the substrate.

[0052] It can be understood that a plurality of electronic components can be provided on the glass substrate PCB. The electronic components are generally protruding from the panel of the glass substrate PCB. The electronic components can include resistors, capacitors, processors, memories, etc. It can be understood that the specific types of electronic components are only shown as some specific examples in some examples of the embodiments of the present application, and are not limited to the specific types of electronic components.

[0053] Figure 4 FIG. 1 is a structural schematic diagram of a housing of a display module provided in some embodiments of the present application.

[0054] In some examples, as shown in FIG. 4, the first mounting surface 1111 can be provided with a relief structure 1111a. The relief structure 1111a can be recessed from the first mounting surface 1111. The relief structure 1111a can be used to avoid the electronic components on the glass substrate PCB 12.

[0055] In some examples, after the glass substrate PCB 12 is mounted on the first mounting surface 1111, the electronic components on the glass substrate PCB 12 can be accommodated in the relief structure 1111a. In this way, the panel of the glass substrate PCB 12 can be in contact with the first mounting surface 1111. Thus, the contact area of the glass substrate PCB 12 and the first mounting surface 1111 can be increased, and the first mounting surface 1111 can support the glass substrate PCB 12 in the case that the glass substrate PCB 12 is subjected to pressure, which is conducive to dispersing the stress on the glass substrate PCB 12 and protecting the glass substrate PCB 12.

[0056] In some examples, as shown in FIG. 4, the first mounting surface 1111 can be provided with a relief structure 1111a. The relief structure 1111a can be recessed from the first mounting surface 1111. The relief structure 1111a can be used to avoid the electronic components on the glass substrate PCB 12. Figure 2 Figure 2 ​The shell body 111 can include a second mounting surface 1112. The second mounting surface 1112 can be connected with the display box.

[0057] The display screen module 10 provided by the embodiments of the present application, wherein the shell 11 includes a shell body 111, the shell body 111 includes a first mounting surface 1111 and a second mounting surface 1112 opposite in the thickness direction, the first mounting surface 1111 is used for mounting the glass-based circuit board 12, and the second mounting surface 1112 is used for connecting with the display box; the avoiding structure 1111a is arranged on the first mounting surface 1111, and the avoiding structure 1111a is recessed in the first mounting surface 1111. In this way, when the glass-based circuit board 12 is mounted on the first mounting surface 1111, the electronic components on the glass-based circuit board 12 can be accommodated in the avoiding structure 1111a, and the thickness of the electronic components on the glass-based circuit board 12 can be absorbed by the avoiding structure 1111a, so that after the glass-based circuit board 12 is mounted on the first mounting surface 1111, the surface of the glass-based circuit board 12 can be attached to the first mounting surface 1111, and the gap between the surface of the glass-based circuit board 12 and the first mounting surface 1111 can be reduced; in the case that the glass-based circuit board 12 is subjected to a front pressure, the pressure can be directly transmitted to the shell body 111, the stress on the glass-based circuit board 12 itself can be dispersed, and the risk of the glass-based circuit board 12 being broken can be reduced, thereby prolonging the service life of the display screen module 10 of the display device.

[0058] In some examples, referring to FIG. 1, Figure 4 As shown in FIG. 1, the avoiding structure 1111a can include a plurality of.

[0059] In some examples, the shape of the avoiding structure 1111a can be adapted to the shape of the electronic component. In other words, the shape of the avoiding structure 1111a can be the same, similar or analogous to the shape of the electronic component. Different shapes of the avoiding structure 1111a can be provided for different shapes of the electronic component.

[0060] In some examples, the arrangement positions of the plurality of avoiding structures 1111a on the first mounting surface 1111 can correspond to the electronic components on the glass-based circuit board 12. In other words, one electronic component can correspond to one avoiding structure 1111a.

[0061] In some examples, in the case that the electronic components are densely arranged on the glass-based circuit board, one avoiding structure 1111a can correspond to a plurality of electronic components. The number of the electronic components corresponding to one avoiding structure 1111a is not limited in the embodiments of the present application.

[0062] In some examples of the embodiments of the present application, by arranging the plurality of avoiding structures 1111a, the arrangement positions of the plurality of avoiding structures 1111a on the first mounting surface 1111 correspond to the electronic components on the glass-based circuit board 12. In this way, after the glass-based circuit board 12 is mounted to the first mounting surface 1111, the electronic components on the glass-based circuit board 12 can be accommodated in the corresponding avoiding structures 1111a, and the thickness of the electronic components themselves can be avoided by the avoiding structures 1111a, so that the plate surface of the glass-based circuit board 12 can be in contact with the first mounting surface 1111, the contact area of the glass-based circuit board 12 and the first mounting surface 1111 is increased, and the gap between the plate surface of the glass-based circuit board 12 and the first mounting surface 1111 can be reduced; in the case that the glass-based circuit board 12 is subjected to a front pressure, the pressure can be directly transmitted to the shell body 111, the stress on the glass-based circuit board 12 itself can be dispersed, so that the risk of the glass-based circuit board 12 being broken can be reduced, and the service life of the display screen module 10 of the display device is improved.

[0063] In some examples, the avoiding structure 1111a can include a groove. The depth of at least part of the plurality of grooves is less than the thickness between the first mounting surface 1111 and the second mounting surface 1112. In other words, at least part of the grooves are recessed from the first mounting surface 1111 and do not penetrate to the second mounting surface 1112.

[0064] In some examples, the depth of any one of the plurality of grooves is less than the thickness between the first mounting surface 1111 and the second mounting surface 1112.

[0065] In some examples, the groove can be recessed from the first mounting surface 1111.

[0066] In some examples, the shell body 111 can include an integrally injection molded integral piece. The shell body 111 can be integrally injection molded by polycarbonate (PC). The groove can be formed in the first mounting surface 1111 during the integrally injection molding.

[0067] It can be understood that, in some examples of the embodiments of the present application, the material of the shell body 111 is only shown as a specific example, and is not limited to the specific material of the shell body 111.

[0068] In some embodiments of this application, the clearance structure 1111a is configured as a recess, and the depth of the recess is less than the thickness between the first mounting surface 1111 and the second mounting surface 1112. Thus, the recess can be recessed from the first mounting surface 1111 without penetrating the second mounting surface 1112. After the glass-based circuit board 12 is mounted on the first mounting surface 1111, the electronic components on the glass-based circuit board 12 can be accommodated within the recess. Since the recess does not penetrate the second mounting surface 1112, the electronic components are not exposed on the second mounting surface 1112, improving the integrity of the display module 10's appearance. Furthermore, the low wall of the recess can protect the electronic components, extending their lifespan.

[0069] In addition, in some embodiments of this application, the shell body 111 is formed by integral injection molding. Thus, one shell body 111 can be fitted with one glass-based circuit board 12. The size of the shell body 111 is reduced compared to the size required to mount multiple glass-based circuit boards 12. The shell body 111 is less prone to bending under external forces, ensuring flatness and dimensional accuracy, which is beneficial for the processing and production of the shell body 111, thereby saving processing and production costs.

[0070] In some examples, refer to Figure 2 and Figure 3 As shown, the housing 11 also includes a hub adapter plate 112. The hub adapter plate 112 can be disposed on the second mounting surface 1112. The hub adapter plate 112 can be fixedly connected to the second mounting surface 1112.

[0071] In some examples, refer to Figure 3 As shown, the second mounting surface 1112 may be provided with multiple mounting posts 1114. The hub adapter plate 112 can be fixed to the mounting posts 1114 by connecting components such as bolts, screws or threaded rods.

[0072] In some examples, refer to Figure 3 and Figure 4 As shown, the housing body 111 may be provided with a through hole 1113 that penetrates the first mounting surface 1111 and the second mounting surface 1112. The through hole 1113 may be opposite to the adapter interface 1121 of the hub adapter plate 112.

[0073] In some examples, the through-hole 1113 can be used to allow the first interface 121 on the glass-based circuit board 12 to pass through and mate with the adapter 1121. The first interface 121 can be a hub interface. The first interface 121 can be electrically connected to electronic components on the glass-based circuit board 12.

[0074] In some examples, the adapter interface 1121 can be used to mate with a second interface on the display box. The second interface can be a hub interface.

[0075] In other words, in some examples of embodiments of the present application, the first interface 121 on the glass-based circuit board 12 passes through the through hole 1113 and is inserted into the adapter interface 1121, and the second interface on the display box can be inserted into the adapter interface 1121, so that the first interface 121 on the glass-based circuit board 12 is connected to the second interface on the display box through the adapter interface 1121.

[0076] In some examples of embodiments of the present application, by providing a hub adapter plate 112, the hub adapter plate 112 is arranged on the second mounting surface 1112, and a through hole 1113 is arranged on the shell body 111 to pass through the first mounting surface 1111 and the second mounting surface 1112, and the through hole 1113 is opposite to the adapter interface 1121 of the hub adapter plate 112. In this way, after the glass-based circuit board 12 is mounted to the first mounting surface 1111, the first interface 121 on the glass-based circuit board 12 can pass through the through hole 1113 and be inserted into the adapter interface 1121 to mate with the adapter interface 1121. When the display screen module 10 is mounted to the display box, the second interface on the display box can be mated with the adapter interface 1121, so that the first interface 121 on the glass-based circuit board 12 can be mated with the second interface on the display box through the adapter interface 1121. That is, when the display screen module 10 is mounted to the display box, the force of the second interface on the display box acts on the adapter interface 1121, which can reduce or eliminate the force transmitted from the second interface to the glass-based circuit board 12 through the first interface 121, thereby reducing the stress on the glass-based circuit board 12 and effectively protecting the glass-based circuit board 12.

[0080] In some examples, the first guiding and positioning structure 1115 can include a guiding post. The second guiding and positioning structure 1122 can include a guiding hole.

[0081] In some examples, the first guiding and positioning structure 1115 can include a guiding hole. The second guiding and positioning structure 1122 can include a guiding post. The guiding post can be inserted into the guiding hole, thereby guiding and positioning the hub adapter plate 112.

[0086] In some examples, referring to FIG. 11B, the display screen module 10 can include a connecting piece 13. The glass-based circuit board 12 can be connected to the first mounting surface 1111 of the shell 11 through the connecting piece 13. Figure 3

[0087] In some examples, the connecting piece 13 can include an adhesive piece. For example, the connecting piece 13 can include double-sided adhesive tape. In other words, the glass-based circuit board 12 can be pasted to the fixed area 1111c through the double-sided adhesive tape, thereby connecting the glass-based circuit board 12 and the shell 11 into an integrated display screen module 10.

[0088] In some examples, referring to FIG. 11B, the display screen module 10 can include a connecting piece 13.
