To make the purpose, technical solution and advantages of the present invention clearer, the following will combine the embodiments of the present invention and the corresponding drawings to clearly and completely describe the technical solution of the present invention. It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The technical solutions disclosed in the embodiments of the present invention are described in detail below with reference to the accompanying drawings.

As shown in fig. 1-5, the embodiment of the utility model discloses a display module assembly, display module assembly includes first display area 100 and second display area 200, and first display area 100 is planar structure, and second display area 200 is cyclic annular structure spare, and second display area 200 encircles and sets up outside first display area 100, and second display area 200 is connected with first display area 100, constitutes display module assembly's display surface jointly.

Specifically, the first display area 100 and the second display area 200 may be a unitary structure, i.e., they are different portions of the same structure. Or, the first display area 100 and the second display area 200 are split structures, and the first display area 100 and the second display area 200 can form a display surface of the display module by splicing the first display area 100 and the second display area 200.

Moreover, by improving the processing precision and the like, the splicing gap between the first display area 100 and the second display area 200 which are spliced can be smaller, and even the splicing gap between the first display area 100 and the second display area 200 can be in a state invisible to naked eyes. In addition, the splicing gap between the first display area 100 and the second display area 200 can be further thinned in the working process of the display module through modes such as an optimization algorithm and the like, and the display effect is improved.

In order to enlarge the display area of the electronic device without enlarging the overall size of the electronic device, the second display surface of the second display area 200 may extend in a direction away from the first display surface of the first display area 100 along the thickness direction of the first display area 100, so that the second display area 200 is bent with respect to the first display area 100. In the electronic equipment that adopts above-mentioned display module assembly, through making second display area 200 encircle and set up around electronic equipment, can guarantee that electronic equipment possesses the display capability all around, promote electronic equipment's screen and account for than, and promote electronic equipment's display effect.

In addition, the second display surface of the second display area 200 can be in an arc-shaped structure, so that the transition between the first display surface and the second display surface is relatively smooth, and the display effect is further improved.

Further, the size of the second display area 200 extending along the thickness direction of the first display area 100 may be determined according to actual requirements such as the thickness of the electronic device. For example, the second display area 200 may cover a portion of the peripheral side of the electronic device, or the second display area 200 and a rear housing and the second display area 200 of the electronic device, which are away from the first display area 100, are arranged at an interval, a middle frame of the electronic device may be arranged in an area between the second display area 200 and the second display area 200, and at least one of a power key, a volume key, a fingerprint identification module, and the like may be arranged on the middle frame.

Optionally, under the condition that electronic equipment adopts above-mentioned display module assembly, can also make the second display surface of second display area 200 cover electronic equipment's side all around completely, under this condition, because electronic equipment's side all is covered by second display area 200, does not have the trompil structure to electronic equipment's dustproof and waterproof performance can be promoted.
