In some embodiments, please refer to fig. 20, and fig. 20 is a schematic structural diagram of a rubber frame according to an embodiment of the present disclosure. The glue frame 12 includes a first glue frame 121 and a second glue frame 122.

The first rubber frame 121 has two parts, which are respectively located at two sides of the overall structure of the rubber frame 12. The first rubber frame 121 has a first gap and a second gap 123. The first notch is used for disposing the second plastic frame 122, and the first notch is not marked in the figure because the first notch is filled by the second plastic frame 122. The second notch 123 is used for avoiding the driving circuit.

In some embodiments, the rubber frame 12 is provided with a first protrusion 125 and a second protrusion 126 at the position of the second notch 123, and the diameter of the first protrusion 125 and the diameter of the second protrusion 126 are larger than the diameter of the rest of the rubber frame 12. The first and

second protrusions

125 and 126 may increase the area at the location of the second notch 123.

In some embodiments, the rubber frame 12 is provided with an arc-shaped portion 127, the arc-shaped portion 127 is an arc-shaped structure, and the arc-shaped portion 127 is formed by protruding outwards. The two arc-shaped portions 127 are adjacent to the first protrusion 125 and the second protrusion 136, respectively.

In some embodiments, the thickness of the first rubber frame 121 may be the same as the thickness of the second rubber frame 122, i.e., the periphery of the first rubber frame 121 and the periphery of the second rubber frame 122 are flush. The thickness of the first rubber frame 121 may be different from the thickness of the second rubber frame 122. The cover plate 110 may be flush with the periphery of the first waterproof layer 121, or flush with the periphery of the second plastic frame, that is, the cover plate 110 may be the same as the first plastic frame 121, or the same as the second plastic frame.

Referring to fig. 21, fig. 21 is another schematic structural diagram of a display screen assembly according to an embodiment of the present disclosure. The display screen assembly 1 may further include a flexible circuit board 17 and a plastic board 18.

The flexible circuit board 17 is electrically connected to the display screen 120 and the backlight module 13 through the second gap 123. At the position where the flexible circuit board 17 is located at the second notch 123, the first bump 125 and the second bump 126 are respectively in close fit with the flexible circuit board 17, so that the waterproof effect can be improved.

The plastic plate 18 is disposed near the second gap 123, and the plastic plate 18 is disposed at the periphery of the display screen 120 and the periphery of the backlight module 13. The plastic plate 18 includes two steps 181, and the two steps 181 are respectively located at two sides of one end of the plastic plate 18. One of the two arc-shaped portions 127 is placed on one of the steps 181, and the other of the two arc-shaped portions 127 is placed on the other step 181.

It should be noted that, in fig. 21, the display screen is not shown because the display screen is shielded by the backlight module 13, and therefore, the display screen is not marked in fig. 21.

The display screen assembly and the electronic device provided by the embodiments of the present application are described in detail above, and the principles and embodiments of the present application are explained herein by applying specific examples, and the descriptions of the above embodiments are only used to help understanding the present application.
