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

In some embodiments, the plastic frame 12 is provided with a first bump 125 and a second bump 126 at the position of the second gap 123 . The diameter of the first bump 125 and the diameter of the second bump 126 are larger than the rest of the plastic frame 12 part diameter. The first bump 125 and the second bump 126 can increase the area at the position of the second notch 123 .

In some embodiments, the plastic 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 to protrude outward. There are two arc-shaped portions 127 , which are respectively adjacent to the first bump 125 and the second bump 136 .

In some embodiments, the thickness of the first plastic frame 121 may be the same as the thickness of the second plastic frame 122 , that is, the periphery of the first plastic frame 121 and the peripheral edge of the second plastic frame 122 are flush. It should be noted that, the thickness of the first plastic frame 121 may also be different from the thickness of the second plastic frame 122 . The cover plate 110 can be flush with the periphery of the first waterproof 121 or with the periphery of the second plastic frame, that is, the cover plate 110 can be the same thickness as the first plastic frame 121 or the second plastic frame of the same thickness.

Please refer to FIG. 21. FIG. 21 is another schematic structural diagram of a display screen assembly provided by an embodiment of the present application. 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 in close contact with the flexible circuit board 17 respectively, which can improve the waterproof effect.

The plastic plate 18 is close to the position of the second notch 123 , and the plastic plate 18 is disposed on 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 .
