With continued reference to fig. 3, the number of first sub-sides 214 may be three, the number of second sub-sides 215 may be one, and three first sub-sides 214 are connected in sequence and then connected with one second sub-side 215 to form a frame-shaped structure. Illustratively, three first sub-sides 214 respectively form a left side, a top side and a right side of the electronic device, a second sub-side 215 is opposite to the top side, and the second sub-side 215 correspondingly forms a bottom side. In this way, the electrical component 202 can be disposed adjacent to the second sub-side 215, and the display screen assembly 220 can avoid damage to the electrical component 202 by the display screen assembly 220 applying a force to the electrical component 202 by overlapping the support step 216 of the second sub-side 215.

In some embodiments, with continued reference to fig. 3, the protective adhesive assembly 230 further includes a third protective adhesive 233, wherein the third protective adhesive 233 is bonded between the first protective adhesive 231 and the second protective adhesive 232. In this way, the third protective colloid 233 is adhered between the first protective colloid 231 and the second protective colloid 232, so that the damage of the electrical component 202 and other parts caused by the dirt such as water, grease, dust and the like entering between the display screen assembly 220 and the supporting portion 211 through the gap between the first protective colloid 231 and the second protective colloid 232 is avoided. The third protective colloid 233 illustratively comprises a silicone colloid, and for example, a liquid silicone glue may be filled between the first protective colloid 231 and the second protective colloid 232, and the third protective colloid 233 is formed by solidification.

Further, in some embodiments, with continued reference to fig. 3, the first protective colloid 231, the second protective colloid 232, and the third protective colloid 233 form a closed ring-shaped structure. The electrical component 202 may be located in the ring structure, so that the first protective colloid 231, the second protective colloid 232 and the third protective colloid 233 cooperate to effectively prevent external dirt such as dust, water and grease from entering the ring structure through the gap between the display screen assembly 220 and the supporting portion 211 to damage the electrical component 202.

FIG. 5 illustrates a partial cross-sectional view of an electronic device shown in the present disclosure according to an exemplary embodiment. In some embodiments, referring to fig. 5, the display screen assembly 220 includes: the display device comprises a transparent cover plate 221 and a display layer 222, wherein the transparent cover plate 221 is attached to one surface, back to the supporting part 211, of the display layer 222, and a protective film 223 is arranged on the side wall of the display layer 222. In this way, the side wall of the display layer 222 is protected by the protective film 223, so that the display layer 222 is prevented from being contaminated or damaged by external dirt such as water, grease, and dust entering the display layer 222. Illustratively, the protective film 223 may be formed on the sidewalls of the display layer 222 using a spraying process. Illustratively, the material of the protective film 223 may include MS glue.

For example, the size of the frame can be reduced by 0.2-0.25 mm. Because the inner wall of the second sub-side 215 is provided with the inwardly protruding supporting step 216, at least one edge of the display screen assembly 220 overlaps the supporting step 216 through the second protective colloid 232, which facilitates the arrangement of the electrical component 202 in the area close to the second sub-side 215, and prevents the display screen assembly 220 from applying a force to the electrical component 202 to damage the electrical component 202. The first protective colloid 231, the second protective colloid 232 and the third protective colloid 233 are matched to effectively protect the electrical component 202. The display layer 222 can be effectively protected by the protective film 223.

The above embodiments of the present disclosure may be complementary to each other without conflict.

The above description is only exemplary of the present disclosure and should not be taken as limiting the disclosure, as any modification, equivalent replacement, or improvement made within the spirit and principle of the present disclosure should be included in the scope of the present disclosure.
