Detailed Description

Reference will now be made in detail to embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following examples do not represent all embodiments consistent with the present application. But merely as exemplifications of systems and methods consistent with certain aspects of the application, as recited in the claims.

The electronic device in the embodiment of the present application may be a device having a display unit, including but not limited to a mobile phone, a tablet computer, a vehicle-mounted device, and the like. The display unit may be used to receive input numeric or character information, generate signal inputs related to user settings and function control of the electronic device, and in particular, may be used to collect touch operations of a user on or near the display unit, such as clicking a button, dragging a scroll box, and the like. The display unit may also be used to display information input by the user or information provided to the user, a Graphical User Interface (GUI) of various menus of the electronic device, and the like. In particular, the display unit may include a display screen disposed on a front surface of the electronic device. The electronic device can display a corresponding picture on the display screen based on the internal electric signal.

Display screens of electronic devices are generally divided into two types according to the degree of curvature of the screen edge, namely a straight display screen and a curved display screen. The curved display screen is made of a flexible material, has the advantages of small thickness, good elasticity, light weight, low power consumption and the like compared with a straight display screen, and is widely applied to electronic equipment.

The edge of the cover plate 3 is bent towards the rear cover 2 by a certain angle, for example, the angle may be less than 90 ° as shown in fig. 3, so that the edge of the screen module 1 presents a curved surface shape with small curvature; the angle may be larger than 90 ° as shown in fig. 4, so that the edge of the screen module 1 has a curved surface with a large curvature. The edge of the rear cover 2 is bent at a certain angle toward the cover plate 3 and is butted against the edge of the cover plate 3.

It should be noted that, no matter the mobile phone with the curved screen has a small curvature form or the mobile phone with the curved screen has a large curvature form, the larger the bending angle of the edge of the cover plate 3 is, in order to ensure the adaptability between the cover plate 3 and the rear cover 2, the smaller the bending angle of the edge of the rear cover 2 should be, the smaller the supporting effect of the rear cover 2 on the cover plate 3 is, so that the edge of the cover plate 3 is easily damaged, and in order to not expose the devices inside the mobile phone with the curved screen, the cover plate 3 and the rear cover 2 are required to be butted to form a sealed cavity, which requires the cover plate 3 and the rear cover 2 to have high adaptability, and a higher requirement is also provided for the operation when the cover plate 3 and the rear cover 2 are connected, thereby reducing the assembly efficiency.

In addition, because the first flange 32 and the second flange 22 are not affected by the curvature of the first bending portion 31 and the second bending portion 21, the bending angle of the screen module 1 of the electronic device with the flange structure can be set in the range of 90 degrees to 180 degrees according to actual requirements, and the problem that the screen module 1 is difficult to assemble with a rear cover when the bending angle exceeds 90 degrees in the prior art is solved. In addition, the electronic equipment with the bending angle of the screen module 1 smaller than 90 degrees can also adopt the edge folding structure, so that the connection area of the joint of the screen module 1 and the rear cover 2 can be increased, and the connection between the screen module 1 and the rear cover 2 is more stable and reliable.
