The touch panel 60 can be connected between the cover assembly 30 and the display module 20, that is, the cover assembly 30, the touch panel 60 and the display module 20 are sequentially stacked. Alternatively, the touch panel 60 is embedded in the display module 20, i.e., the touch panel 60 is integrated in the display module 20.

When the cover assembly 30 is disposed, the cover assembly 30 is transparent to allow a user to see the contents displayed by the display module 20, and the cover assembly 30 satisfies a certain hardness requirement for protecting the touch panel 60 and the display module 20 under the cover assembly 30. The cover plate assembly 30 may be made of glass or other material that meets the requirements of light transmission and rigidity.

In the case of providing the first filling region 12a and the second filling region 12b, referring to fig. 4, a distance C1 between the outer edge 21 of the display module 20 and the inner side 122 of the bezel 12 (i.e., a thickness of the adhesive 40 in the first filling region 12 a) may be set to be 0.2 to 0.5 mm. The wall thickness C2 of the side 123 of the frame 12 of the housing 10 facing away from the support plate 11 can be set to 0.2 to 0.6 mm. The adhesive 40 in the first filling region 12a and the second filling region 12b is disposed in accordance with the above-mentioned size range, so that reliable connection between the rear edge 32 of the cover plate assembly 30 and the side 123 of the bezel 12, and between the outer edge 21 of the display module 20 and the inner side 122 of the bezel 12 can be achieved. The projection of the adhesive 40 on the housing 10 occupies a small proportion of the front area of the mobile terminal, and the ultra-narrow frame 12 is implemented to improve the screen occupation ratio. Illustratively, the distance C1 between the outer edge 21 of the display module 20 and the inner side 122 of the bezel 12 is 0.25 mm. The wall thickness C2 of the side 123 of the rim 12 facing away from the support plate 11 is 0.35 mm. The specific size is set as required.

In some embodiments, referring to fig. 4, the hardness of the adhesive 40 in the first filling region 12a after curing is less than or equal to the hardness of the adhesive 40 in the second filling region 12b after curing. The bonding glue 40 located in the first filling area 12a is inner layer glue, the bonding glue 40 located in the second filling area 12b is outer layer glue, and the inner layer glue is connected with the outer layer glue. The cured outer layer glue is a hard glue, which facilitates reliable bonding of the cover plate assembly 30 to the side 123 of the frame 12 and obtains a good appearance. The inlayer glue after the solidification is the flexible glue, does benefit to and fully fills glue between the medial surface 122 of the outward flange 21 of display module assembly 20 and frame 12 to do not have the damage to display module assembly 20, promote display module assembly 20's stability.

There are different implementations when the adhesive glue 40 is provided. The first adhesive glue is realized by the following steps: the adhesive 40 is a shadowless adhesive, which is also called UV curable adhesive (UV adhesive). The shadow-less glue in the first filling region 12a is cured by moisture, and the shadow-less glue in the second filling region 12b is cured by uv light. The ultraviolet curing means that: the adhesive glue is irradiated by ultraviolet light to be converted from a liquid state to a solid state.

In assembly, referring to fig. 5, the liquid shadowless adhesive is firstly disposed in the corresponding area of the frame 12 of the housing 10, and with reference to fig. 6, the display module 20 and the cover plate assembly 30 are then mounted on the housing 10, and the overflowing shadowless adhesive is erased (as shown in fig. 4). The shadowless glue in the second filling area 12b is used as outer glue, and the outer glue is converted from a liquid state to a solid state through ultraviolet irradiation, so that the integrated bonding of the back edge 32 of the cover plate assembly 30 and one side 123 of the frame 12 is realized, and a good appearance effect is obtained. The shadowless glue that is located first filling area 12a forms the flexible glue as inlayer glue through the moisture solidification, realizes the abundant packing of flexible glue between the outward flange 21 of display module assembly 20 and the medial surface 122 of frame 12, and the flexible glue does not have the damage to display module assembly 20 to realize water-proof effects.

The second adhesive glue is realized by the following steps: the adhesive 40 is an acrylic adhesive, the acrylic adhesive in the first filling area 12a is cured by moisture to form an inner soft adhesive, and the acrylic adhesive in the second filling area 12b is cured by ultraviolet light to form an outer hard adhesive. The process of bonding the cover plate assembly 30, the display module 20 and the frame 12 by using the acrylic adhesive is similar to the assembly condition of using the ultraviolet curing adhesive, and is not described again. The third implementation manner of the adhesive glue is as follows: the adhesive 40 is a silicone adhesive. During assembly, the liquid silicone adhesive is first disposed on the frame 12 of the housing 10, the display module 20 and the cover plate assembly 30 are then mounted on the housing 10, and the overflowing silicone adhesive is wiped off. The liquid silicone adhesive can be cured at room temperature or by heating, so that the connection between the back edge 32 of the cover plate assembly 30, the outer edge 21 of the display module 20 and the frame 12 is realized, a good appearance is obtained, and a waterproof effect is realized. The cured organic silicon adhesive has certain elasticity and does not damage the display module 20.

The fourth implementation manner of the adhesive glue is as follows: the adhesive 40 is a Reactive Polyurethane Reactive (PUR) hot melt adhesive, which is cured after being heated and melted, so as to connect the back edge 32 of the cover plate assembly 30, the outer edge 21 of the display module 20, and the frame 12. During the equipment, earlier locate the PUR glue on the frame 12 of casing 10, heat the PUR glue until melting, bond display module assembly 20 and apron subassembly 30 on casing 10 frame 12 again, make the PUR glue connect between the back edge 32 of apron subassembly 30 and one side 123 of frame 12 to and between the medial surface 122 of the outward flange 21 of display module assembly 20 and frame 12, the PUR glue takes place the reaction solidification through the moisture in the air, accomplish the equipment.

It can be understood that can also choose for use other accessible moisture solidification and ultraviolet curing's bonding adhesive, make the bonding adhesive that is located first filling area pass through the moisture solidification, and the bonding adhesive that is located the second filling area passes through ultraviolet curing to form the structure that inlayer gum and outer ebonite, realize the reliable connection between display module assembly, apron subassembly and the frame, effective waterproof, and effectively protect display module assembly.

When the above different adhesive glues 40 are used for assembly, referring to fig. 5, the adhesive glue 40 is firstly disposed on the frame 12 of the housing 10, and with reference to fig. 6, the display module 20 and the cover plate assembly 30 are then mounted on the housing 10, and the adhesive glue 40 overflowing out of the second filling area 12b can be wiped off by a conventional glue wiping machine (not shown) (as shown in fig. 4), so as to obtain a good appearance. Finally, the housing 10, the display module 20 and the cover plate assembly 30 are fixed by a pressure maintaining device (not shown) to wait for the adhesive 40 to be cured. Illustratively, the pressure maintaining device includes an upper mold and a lower mold, the assembled mobile terminal is placed between the upper mold and the lower mold, the upper mold and the lower mold are locked by a fastener or other means, and the upper mold and the lower mold apply pressure to the mobile terminal to wait for the adhesive 40 to cure, so as to achieve tight connection of the housing 10, the display module 20 and the cover assembly 30.

In some embodiments, referring to fig. 4 and 5, the cover assembly 30 includes a transparent cover 33 and a protective frame 34 disposed on an edge of the transparent cover 33, wherein an outer edge of the protective frame 34 is flush with an outer edge 121 of the bezel 12. The outer edge of the bezel 34 is the outer edge 31 of the cover plate assembly 30. When the light-transmitting cover plate 33 adopts a glass plate, the protective frame 34 is arranged around the glass plate, so that the strength of the whole structure can be improved, the protective frame 34 plays a role in buffering to a certain extent, the condition that the glass plate is collided and broken is reduced, and the reliability of the display structure is improved.
