[0046] Optionally, the thickness of the front frame 40 is between 0.15 mm and 0.3 mm, for example, 0.15 mm, 0.2 mm, 0.25 mm or 0.3 mm.

[0047] Optionally, the material of the front frame 40 may be metal or metal alloy. The front frame 40 is formed by a stamping process.

[0056] It is understandable that the convex structure 424 is formed on the shielding portion 421 and the protective film 60 is clamped by the convex structure 424 , so as to improve the firmness of the shielding portion 421 and the end portion 423 in clamping the protective film 60 based on the concentrated effect of the clamping force.

[0057] Optionally, in some embodiments, a convex structure 424 is also formed on the side of the end portion 423 close to the protective film 60 to improve the firmness of the shielding portion 421 and the end portion 423 in clamping the protective film 60 .

[0058] Optionally, in some embodiments, the convex structure 424 on the end portion 423 and the convex structure 424 on the shielding portion 421 are staggered with each other to improve the firmness of the shielding portion 421 and the end portion 423 clamping the protective film 60.

[0059] Optionally, the convex structure 424 can be a bump or a raised stripe, etc.

[0060] Optionally, in some embodiments of the present application, the shielding portion 421 includes a first segment 42a, a second segment 42b and a third segment 42c.

[0062] It can be understood that the end portion 423 can be arranged in the sink 4a to improve the flatness of the outer side of the side plate 42 in the front frame 40 and reduce the risk of interference with the shell assembly.

[0063] In some embodiments, the convex structure 424 can be directly arranged on the side of the third segment 42c close to the end portion 423.

[0064] In some embodiments, the side of the third segment 42c close to the end portion 423 is formed with a recess 4a1, and part of the convex structure 424 is arranged in the recess 4a1. Part of the convex structure 424 is arranged in the recess 4a1 to reduce the risk of the convex structure 424 protruding outward too much.

[0065] Optionally, in some embodiments of the present application, in a direction perpendicular to the thickness direction F1 of the display device 100, the depth L of the sink 4a is greater than or equal to the thickness of the end portion 423.

[0066] It should be understood that, based on the protective film 60 being clamped between the shielding portion 421 and the end portion 423, part of the protective film 60 is also arranged in the sink 4a. Therefore, the depth L of the sink 4a is greater than or equal to the thickness of the end portion 423, which can better improve the flatness of the side of the display device 100 to improve the appearance effect.

[0067] Optionally, the depth L of the sink 4a is between 0.05 mm and 0.2 mm, such as 0.05 mm, 0.1 mm, 0.15 mm or 0.2 mm, etc.

[0070] Optionally, in some embodiments of the present application, the angle a between the extension direction of the second section 42b and the extension direction of the first section 42a is obtuse.

[0071] It can be understood that the second section 42b is arranged in an inclined manner, not only forming the sink 4a, but also allowing the flexible circuit board 30 to contact the side plate 42 along the inclination of the second section 42b. Compared with the punctate contact of the side plate 42 with the flexible circuit board 30, the embodiment of the present application reduces the risk of damage to the flexible circuit board 30 due to stress concentration during transportation.

[0072] Secondly, the second section 42b is arranged in an inclined manner, so that the upper section of the sink 4a has a guiding effect, facilitating the smooth entry of the protective film 60 between the end portion 423 and the shielding portion 421.

[0073] Optionally, in some embodiments of the present application, the angle β between the extension direction of the second section 42b and the extension direction of the third section 42c is obtuse, so as to form a gentle sink 4a, facilitate the arrangement of the end portion 423 in the sink 4a, and allow the flexible circuit board 30 to contact the side plate 42 along the inclination of the second section 42b. Compared with the punctate contact of the side plate 42 with the flexible circuit board 30, the embodiment of the present application reduces the risk of damage to the flexible circuit board 30 due to stress concentration during transportation.

[0074] Optionally, in some embodiments of the present application, the cover plate 41, the first section 42a, the second section 42b, the third section 42c, the bending portion 422, and the end portion 423 are integrally formed, so as to improve the stability of the front frame 40.

Part of the main body layer 61 and the functional layer 62 are arranged between the end portion 423 and the shielding portion 421.

[0076] It can be understood that the main body layer 61 is configured to shield and protect the flexible circuit board 30 and the printed circuit board 50. The functional layer 62 is configured to protect the main body layer 61 from being pinched by the end portion 423 and the shielding portion 421.

[0077] In some embodiments, the functional layer 62 is arranged only in the area of the sink 4a.

[0078] In some embodiments, the functional layer 62 can be arranged on one side of the main body layer 61 or on the opposite side of the main body layer 61.

[0079] Optionally, the material of the main body layer 61 can be PET or the like. The functional layer 62 can be a hard material or a flexible material, such as ceramic material, rubber or silicone.

[0080] Optionally, in some embodiments of the present application, the hardness of the functional layer 62 is greater than the hardness of the main body layer 61.

[0081] It can be understood that the hardness of the functional layer 62 is greater than the hardness of the main body layer 61, so as to improve the wear resistance and stiffness of the protective film 60, facilitate the insertion of the protective film 60 between the end portion 423 and the shielding portion 421, and better protect the main body layer 61 and reduce the risk of damage to the protective film 60.

[0082] Optionally, in some embodiments of the present application, the functional layer 62 is an elastic material. The functional layer 62 is clamped between the end portion 423 and the shielding portion 421 and stores elastic potential energy.

[0083] It can be understood that the functional layer 62 is clamped between the end portion 423 and the shielding portion 421 and stores elastic potential energy, that is, the functional layer 62 is compressed and deformed by being clamped by the end portion 423 and the shielding portion 421, so that the functional layer 62 is arranged in interference between the end portion 423 and the shielding portion 421, so as to improve the firmness of the end portion 423 and the shielding portion 421 clamping the protective film 60.

[0084] Secondly, since the functional layer 62 stores elastic potential energy, it has a rebounding force. When the clamping force of the end portion 423 and the shielding portion 421 decreases due to stress fatigue, the functional layer 62 can gradually recover to its original shape, so as to keep the functional layer 62 arranged in interference between the end portion 423 and the shielding portion 421, and improve the firmness of the fixed connection of the three.

[0085] Optionally, in some embodiments of the present application, one side of the functional layer 62 in contact with the shielding portion 421 is formed with a microstructure 63, and the microstructure 63 abuts against the shielding portion 421.

[0086] It can be understood that the arrangement of the microstructure 63 can increase the surface friction coefficient of the functional layer 62, and further increase the static friction force between the functional layer 62 and the shielding portion 421, so as to improve the firmness of the shielding portion 421 and the end portion 423 clamping the protective film 60.

[0087] Optionally, the microstructure 63 can be a stripe or a convex point, etc. Taking the stripe as an example, a plurality of stripes are cross-connected to form a grid structure to improve the friction coefficient.

[0089] Optionally, in some embodiments, one of the microstructure 63 and the convex structure 424 is a grid structure formed by cross-connecting stripes, and the other is a convex point arranged in a grid cell of the grid structure, which not only improves the firmness of clamping, but also reduces the risk of the protective film 60 separating from the clamping structure formed by the end portion 423 and the shielding portion 421.

[0090] Optionally, in some embodiments of the present application, the friction coefficient of the functional layer 62 is greater than or equal to 0.3, so as to better improve the static friction force between the functional layer 62 and the shielding portion 421, and improve the firmness of clamping the protective film 60 by the shielding portion 421 and the end portion 423.

[0091] Optionally, the friction coefficient of the functional layer 62 can be 0.3, 0.31, 0.32, 0.33, 0.34, 0.35, 0.36, 0.37, 0.38, 0.39 or 0.4, etc.
