[0030] See also Figure 1 , Figure 3 and Figure 5A display module 10 provided in an embodiment of the present application includes a bottom shell 100, a glass substrate 200 and a buffer 300. The glass substrate 200 is made of a glass material. The glass substrate 200 is stacked on the bottom shell 100 so that the edges of the glass substrate 200 and the bottom shell 100 are flush with each other. The glass substrate 200 and the bottom shell 100 can both be rectangular. The buffer 300 has a certain degree of flexibility and elasticity. For example, the buffer 300 can be made of a sponge material, a polypropylene material or a rubber material. The buffer 300 is connected to the bottom shell 100 and / or the glass substrate 200. For example, the buffer 300 can be connected to the glass substrate 200 alone, or the buffer 300 can also be connected to the bottom shell 100 alone, or the buffer 300 can also be connected to the bottom shell 100 and the glass substrate 200 at the same time. The buffer member 300 has a buffer portion 310 . The buffer portion 310 may be located outside the glass substrate 200 and the bottom case 100 . The buffer portion 310 may be deformed. The deformed buffer portion 310 may cover the edge of the glass substrate 200 .

[0031] During the transportation of the display module 10, a human hand or a robot can abut against the buffer portion 310, so that the buffer portion 310 is deformed to cover the edge of the glass substrate 200, thereby preventing the human hand or the robot from impacting the edge of the glass substrate 200, and avoiding damage to the edge of the glass substrate 200 due to stress concentration under the action of the impact force, thereby improving the service life of the display module 10. When the display module 10 is placed in a transfer box for transportation, the buffer portion 310 will abut between the transfer box and the glass substrate 200, and the buffer portion 310 will also be deformed to cover the edge of the glass substrate 200. Therefore, during the transportation process of the transfer box, most of the impact force acting on the transfer box will be absorbed by the buffer portion 310, thereby preventing a large impact force from being transmitted to the edge of the glass substrate 200 and causing damage to it, thereby improving the service life of the display module 10.

[0032] See also Figure 1 and Figure 3In some embodiments, the bottom case 100 includes a first bearing layer 110 and a second bearing layer 120. The thickness of the first bearing layer 110 may be greater than or equal to the thickness of the second bearing layer 120, so that the entire bottom case 100 has a reasonable structural strength. The first bearing layer 110 and the second bearing layer 120 are stacked on each other, and the glass substrate 200 is stacked on the second bearing layer 120, that is, the second bearing layer 120 is stacked between the first bearing layer 110 and the glass substrate 200. The first bearing layer 110 and the second bearing layer 120 are detachably connected. When the first bearing layer 110 and the second bearing layer 120 are connected to each other, the buffer 300 will be sandwiched between the first bearing layer 110 and the second bearing layer 120, and the buffer 300 does not form an irremovable adhesive connection relationship with the first bearing layer 110 and the second bearing layer 120. After the first bearing layer 110 and the second bearing layer 120 are unloaded from each other, the clamping force of the first bearing layer 110 and the second bearing layer 120 on the buffer 300 can be released, so that the buffer 300 can be unloaded from the entire bottom shell 100, and finally the detachable connection relationship between the buffer 300 and the bottom shell 100 and the glass substrate 200 is realized. Therefore, when the buffer 300 is damaged, the first bearing layer 110 and the second bearing layer 120 can be disassembled to realize the unloading of the buffer 300, so as to realize the replacement of the buffer 300, and finally improve the convenience of maintenance of the display module 10. Obviously, after the buffer 300 is sandwiched between the first bearing layer 110 and the second bearing layer 120, the buffer part 310 will be located outside the glass substrate 200, the first bearing layer 110 and the second bearing layer 120.

[0033] See also Figure 1 and Figure 3 In some embodiments, the bottom shell 100 may further include a fastener 130, which is inserted into the first bearing layer 110 and is threadedly connected to the second bearing layer 120. Therefore, the first bearing layer 110 and the second bearing layer 120 may be fixedly connected by the fastener 130. When the fastener 130 is tightened, the first bearing layer 110 and the second bearing layer 120 may be fixedly connected to each other, and when the fastener 130 is loosened, the first bearing layer 110 and the second bearing layer 120 may be unloaded from each other. In other embodiments, the first bearing layer 110 and the second bearing layer 120 may be fixed by a snap-fit ​​connection or the like.

[0034] See also Figure 1 and Figure 3In some embodiments, a groove 111 is formed on the side of the first carrier layer 110, a through hole 112 is formed on the side wall of the groove 111, a fastener 130 is passed through the through hole 112, and the buffer portion 310 can be received in the groove 111. When multiple display modules 10 need to be spliced, the buffer portion 310 can be bent and received in the groove 111, thereby preventing the buffer 300 from affecting the joint between two adjacent display modules 10, and improving the splicing accuracy and splicing efficiency between the display modules 10.

[0035] See also Figure 1 and Figure 3 In some embodiments, the fastener 130 includes a fastening portion 131 and a knob portion 132, and the fastening portion 131 and the knob portion 132 are connected at an angle, for example, the angle between the fastening portion 131 and the knob portion 132 is 90°, that is, the fastening portion 131 and the knob portion 132 are arranged perpendicular to each other. A through hole 112 is provided on the side wall of the groove 111, and an external thread is provided on the fastening portion 131. The fastening portion 131 is inserted into the through hole 112 and meshes with the internal thread on the second bearing layer 120, thereby realizing a threaded connection relationship between the fastening portion 131 and the second bearing layer 120. When the first bearing layer 110 and the second bearing layer 120 are fixedly connected by the fastener 130, the knob portion 132 of the fastener 130 will be accommodated in the groove 111, so the groove 111 provides a good avoidance space for the knob portion 132. During the splicing process of the display modules 10 , the knob portion 132 can be effectively prevented from extending out of the groove 111 to cause interference, thereby preventing the interference of the knob portion 132 from affecting the joints between the display modules 10 , thereby improving the splicing accuracy and efficiency between the display modules 10 .

[0036] See also Figure 3 , Figure 4 and Figure 5 Before the display modules 10 are spliced, the buffer portion 310 can be accommodated in the groove 111, and the knob portion 132 can apply a certain pressure to the buffer portion 310 in the groove 111, so that the knob portion 132 has a limiting function on the buffer portion 310 in the groove 111, and the buffer portion 310 in the groove 111 is abutted between the second bearing layer 120 and the knob portion 132 through the knob portion 132, so that the buffer portion 310 is difficult to fall off the groove 111, thereby improving the convenience of splicing between the two display modules 10, avoiding the buffer portion 310 extending from the groove 111 to affect the splicing between the two display modules 10, and finally improving the splicing accuracy and splicing efficiency between the two display modules 10.

[0037] In some embodiments, since the buffer portion 310 is located outside the glass substrate 200 and the bottom shell 100, the buffer portion 310 is protruded from the edges of the glass substrate 200 and the bottom shell 100. There may be multiple buffer portions 310, and the multiple buffer portions 310 may be arranged at intervals along the circumference of the glass substrate 200. When the buffer portion 310 is deformed, the multiple deformed buffer portions 310 may cover the entire edge of the glass substrate 200, thereby preventing the edge of the glass substrate 200 from being damaged under external impact, thereby improving the service life of the display module 10.

[0038] See also Figure 1 and Figure 2 In some embodiments, the edge of the buffer portion 310 on the bottom shell 100 and the glass substrate 200 is recorded as the installation edge 11. When the buffer portion 310 is located outside the groove 111, the knob portion 132 is located at the first position. At this time, the knob portion 132 is perpendicular to the extension direction of the installation edge 11. Figure 3 and Figure 4 When the buffer portion 310 is located in the groove 111, the knob portion 132 is located in the second position. At this time, the knob portion 132 is parallel to the extension direction of the mounting edge 11. The knob portion 132 located in the first position is farther away from the bottom wall of the groove 111 than the knob portion 132 located in the second position. Since the knob portion 132 in the first position is farther away from the bottom wall of the groove 111 than the knob portion 132 in the second position, when the buffer portion 310 needs to be accommodated in the groove 111, it is convenient to manually hold the knob portion 132 for operation, that is, to hold the knob portion 132 and rotate it from the first position to the second position, so that the knob portion 132 located in the second position plays a good role in limiting the buffer portion 310, and prevents the buffer portion 310 from being exposed from the groove 111 and affecting the splicing accuracy between the display modules 10.

[0039] In summary, during the transportation of the display module 10, a human hand or a robot can abut against the buffer portion 310, so that the buffer portion 310 is deformed to cover the edge of the glass substrate 200, preventing the human hand or the robot from impacting the edge of the glass substrate 200, and avoiding the edge of the glass substrate 200 from being damaged due to stress concentration under the action of the impact force, thereby improving the service life of the display module 10. When the display module 10 is placed in a transport device such as a transport box for transportation, the buffer portion 310 will abut between the transport box and the glass substrate 200, and the buffer portion 310 will also be deformed to cover the edge of the glass substrate 200. Therefore, during the transportation process of the transport box, most of the impact force acting on the transport box will be absorbed by the buffer portion 310, thereby preventing a large impact force from being transmitted to the edge of the glass substrate 200 and causing damage to it, thereby improving the service life of the display module 10.

It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
