Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 2 to 9, a mobile terminal includes a housing 21 and a display module 22 assembled in the housing 21, where the display module 22 includes a display screen 221 and a cover plate 222 attached to the display screen 221, a protective layer 223 is attached to a side wall of the display screen 221, a dispensing slot 23 is formed by a frame 211 of the housing 21, a side wall of the cover plate 222 and the protective layer 223 together, a glue object 24 is filled in the dispensing slot 23, and a side wall of the cover plate 222 is fixedly connected to the frame 211 of the housing 21 through the glue object 24.

The protection layer 223 may be made of an elastic or soft material, for example, the protection layer 223 may be made of sponge, foam, rubber, or silica gel. In addition, the protective layer 223 can be attached to the sidewall of the display 221 in various ways, for example, by glue, solid glue, or double-sided glue.

Since the double-sided adhesive tape has the characteristics of easy forming, easy adhesion, easy tearing and the like, in the embodiment of the invention, the protective layer 223 is preferably attached to the sidewall of the display screen 221 through the double-sided adhesive layer 25.

The adhesive material 24 filled in the dispensing groove 23 may be a curable glue, and after the glue is dispensed into the dispensing groove 23, the glue is gradually cured and hardened with time, and bonds the side wall of the cover plate 222 and the frame 211 of the housing 21.

The cover plate 222 should be made of a material with good light transmittance, and may be, for example, a glass cover plate, a PET (Polyester) cover plate, or a plastic glass cover plate. In addition, the display screen 221 may be, but is not limited to, an OLED (Organic Light-Emitting Diode) display screen.

The mobile terminal of the embodiment of the invention can comprise: at least one of a cell phone, a tablet, an e-book reader, an MP3 player, an MP4 player, a digital camera, a laptop, a car computer, a desktop computer, a set-top box, a smart tv, a wearable device.

In the embodiment of the present invention, due to the arrangement of the protection layer 223, the adhesive object 24 in the dispensing slot 23 can be supported by the protection layer 223, the protection layer 223 is attached to the sidewall of the display screen 221, and the cover plate 222 covers the display screen 221. Thus, the adhesive object 24 in the dispensing slot 23 does not contact the display screen 221. Therefore, the adhesive object 24 does not damage the display screen 221 when it is set and hardened. In addition, when the mobile terminal is dropped or collided by an external force, the protective layer 223 can also play a role in buffering and protecting the display screen 221.

Because the sealing performance and the adsorption performance of the foam are good, the ability of the foam to prevent the adhesive object 24 from penetrating is also good, and therefore, in the embodiment of the present invention, the protection layer 223 is preferably made of foam.

In the embodiment of the present invention, by disposing the protective layer 223 between the display screen 221 and the housing 21, the dispensing slot 23 may be formed between the side wall of the cover plate 222 and the frame 211 of the housing 21, so that the assembly between the cover plate 222 and the housing 21 may be achieved by dispensing the side of the cover plate 222. In the embodiment of the invention, the side wall of the cover plate 222 is used as the dispensing area connected with the shell 21, so that the effective display area of the cover plate 222 is not occupied. As shown in fig. 4, L2 is the width of the non-display area in the embodiment of the present invention, and as can be seen from a comparison between fig. 1 and fig. 4, L2 is significantly smaller than L1. Therefore, the embodiment of the invention can improve the screen occupation ratio of the mobile terminal.

Optionally, the cover plate 222 extends out of the display screen 221, and the cover plate 222 overlaps the protective layer 223.

In order to prevent damage to the display screen 221 due to slight penetration of the adhesive object 24, the cover plate 222 may extend beyond the display screen 221, and the cover plate 222 overlaps the protective layer 223, considering that the adhesive object 24 may slightly penetrate under the cover plate 222 before setting and hardening. Thus, on the one hand, the distance between the edge of the cover plate 222 and the display screen 221 is suitably increased, which distance makes the display screen 221 further away from the adhesive object 24; on the other hand, the overlapping of the cover plate 222 and the protective layer 223 can also appropriately prevent the adhesive object 24 from penetrating into the display screen 221. In addition, the size of the cover plate 222 is larger than that of the display screen 221, so that the cover plate 222 can better protect the display screen 221.

Optionally, as shown in fig. 9, a light-transmitting film 26 is disposed between the cover plate 222 and the display screen 221, the light-transmitting film 26 extends out of the display screen 221, and the light-transmitting film 26 is overlapped with the protective layer 223.

In the embodiment of the invention, the light-transmitting film 26 is arranged between the cover plate 222 and the display screen 221, and the light-transmitting film 26 extends out of the display screen 221, so that the adhesive object 24 can be better isolated and blocked by the light-transmitting film 26, and the protection effect on the display screen 221 can be further improved.

The light-transmitting film 26 may be a PET film.

Optionally, the light transmissive film 26 extends to the rim 211 of the housing 21.

In the embodiment of the present invention, since the light-transmitting film 26 extends to the frame 211 of the housing 21, the light-transmitting film 26 can completely block and isolate the adhesive object 24, and the protection effect on the display screen 221 can be further improved.

The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present invention, and the changes or substitutions should be covered within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
