Illustratively, the first sub-portion 410 and the second sub-portion 420 are each convex to opposite sides of the third sub-portion 430.

In the above embodiment, the joint of the third sub-portion 430 and the first sub-portion 410 forms a first bending portion, and the joint of the third sub-portion 430 and the second sub-portion 420 forms a second bending portion, so that during the installation of the connecting frame 400, the size of the included angle between the third sub-portion 430 and the first sub-portion 410 and/or the size of the included angle between the third sub-portion 430 and the second sub-portion 420 can be adjusted, so that the second sub-portion 420 can be abutted against the display module 300. In addition, the elasticity of the link 400 may be increased by the first and second bending portions, and thus the manufacturing error of the link 400 and the front case 200 may be compensated by the elasticity of the link 400 itself. Therefore, the solution described in this embodiment is not only beneficial to improving the assembling stability of the connection frame 400, the front case 200 and the display module 300, but also beneficial to reducing the manufacturing difficulty of the connection frame 400 and the front case 200 by reducing the manufacturing precision of the connection frame 400 and the front case 200.

In some alternative embodiments, the connecting frame 400 may be formed by stamping. Specifically, the connecting frame 400 may be stamped and formed from a metal block. Optionally, the material of the connecting frame 400 includes at least one of aluminum, iron, and copper.

Illustratively, screws are threadedly coupled to front housing 200 through mounting holes 412.

In some alternative embodiments, the positioning portion 411 is embedded in the positioning groove 210, and the connection member 500 is threaded with the threaded hole 240 through the mounting hole 412, so that not only the first sub-portion 410 can be limited to rotate relative to the front housing 200, but also the first sub-portion 410 and the front housing 200 can be firmly connected by the connection member 500. In addition, during the installation process, the connection member 500 is prevented from rotating relative to the front case 200 and causing the connection frame 400 to rotate relative to the front case 200. Therefore, it is beneficial to improve the assembling precision of the connecting rack 400 and the front case 200 and reduce the assembling difficulty of the connecting rack 400 and the front case 200.

Alternatively, the edge of the front case 200 and the edge of the backlight assembly 100 may be connected by, but not limited to, screws or snaps.

In the assembly process of the display device according to the above-mentioned embodiment, the front case 200 and the display module 300 may be bent along the arc-shaped concave surface by using the force of the connection between the backlight module 100 and the front case 200. Since the side of the backlight module 100 close to the display module 300 is an arc-shaped concave surface, the embodiment can prevent the display module 300 from forming a convex portion protruding to the light-emitting side of the backlight module 100. In addition, in the display device provided in this embodiment, after the front case 200, the display module 300 and the backlight module 100 are assembled, internal stress of the front case 200 and the backlight module 100 can be increased, which is beneficial to further improving the bending resistance of the front case 200.

Referring to fig. 12 and 14, in some further alternative embodiments, the display module 300 includes a display panel 310 and an infrared touch panel 320; the infrared touch panel 320 is stacked on the display panel 310, the infrared touch panel 320 is located at a side away from the backlight module 100, and the infrared touch panel 320 is located between the front case 200 and the display panel 310. As an alternative embodiment, the infrared touch panel 320 is adhered to a side of the display panel 310 away from the backlight module 100. Further optionally, the display device further includes an infrared light source assembly 700. Optionally, the infrared light source assembly 700 is disposed on the front case 200, and the infrared light source assembly 700 is located on a side of the infrared touch panel 320 facing away from the backlight module 100.

In the above embodiment, the infrared touch panel 320 may be located on the display side of the display panel 310, so that the infrared touch panel 320 may protect the display panel 310 on one hand, and on the other hand, the touch surface of the infrared touch panel 320 is a surface facing away from the display panel 310 on one side, light of a display image of the display panel 310 may pass through the infrared touch panel 320 to be displayed, a position on the image displayed by the display panel 310 corresponds to a corresponding coordinate on the touch surface of the infrared touch panel 320, and a user may perform a touch operation on the touch surface of the infrared touch panel 320 according to the image displayed by the display panel 310.

Further optionally, the front case 200 includes a body portion 230 and an extension portion 250. Illustratively, the main body 230 is located on a side of the infrared touch panel 320 facing away from the backlight module 100. The extension portion 250 is connected to the main body portion 230, and the extension portion 250 is disposed around the periphery of the display panel 310 and/or the infrared touch panel 320 to protect the edge of the display panel 310 and/or the infrared touch panel 320 by the extension portion 250. Further optionally, the extension portion 250 is overlapped with the edge of the backlight module 100 in the third direction, and the extension portion 250 is connected to the backlight module 100 in a sealing manner, so as to improve the sealing performance of the display device and improve the waterproof and dustproof performance of the display device.

In some alternative embodiments, the infrared light source assembly 700 is disposed at the body part 230 to detect and position the contact position by the infrared light source assembly 700 forming an infrared matrix in a first direction and a second direction. Optionally, the infrared light source assembly 700 includes a plurality of infrared light sources and infrared light receiving ends corresponding to the infrared light sources one to one. The infrared light source and the infrared receiving end are arranged oppositely, so that infrared light emitted by the infrared light source can be received by the corresponding infrared receiving end. In the process of touching the touch panel, the fingers can shield infrared light emitted by partial infrared light sources, so that infrared signals received by infrared receiving ends at partial positions are weakened, and the positions of the contacts can be determined according to the strength of the infrared signals received by the infrared receiving ends in the first direction and the second direction.

In the display device described in the present application, the ability of front housing 200 to resist distortion can be improved, and it is then beneficial to prevent front housing 200 from distorting and causing the infrared signal received by the partial infrared receiving end to weaken. Therefore, the scheme provided by the application is beneficial to improving the touch performance of the display device.

In addition, in some optional embodiments of the present application, one side of the backlight module 100 close to the display module 300 is an arc-shaped concave surface, the edge of the front housing 200 is connected to the backlight module 100, and the front housing 200 and the display module 300 are bent along the arc-shaped concave surface, so that it is avoided that a convex portion formed by the display module 300 and/or the infrared touch panel 320 blocks infrared light emitted by the infrared light source, and it is beneficial to improving the touch performance of the display device.

In some optional embodiments, as shown in fig. 10, a height difference between the bottom of one side of the display surface of the infrared touch panel 320 and the edge of the display surface of the infrared touch panel 320 in the light emitting direction of the backlight module 100 is L1.
