Further, the caulking glue is dripped into the gap between the inner surface 41 and the touch screen 1 and the display screen 2 through a glue dispenser, so as to seal the gap.

Further, the touch screen 1 and the display screen 2 are attached by OCA (Optically Clear Adhesiv, optically transparent adhesive).

Further, the caulking glue includes: UV (Ultraviolet Rays, shadowless glue) or silica gel.

Further, the outer surface 43 of the middle frame 4 of the mobile phone is a smooth arc surface.

Further, the height of the middle frame 4 of the mobile phone is lower than the height of the touch screen 1 and the display screen 2 on the rib 42 after bonding.

Further, the display screen 2 is an LCM (Liquid Crystal Display Module, liquid crystal display module) display screen.

Furthermore, the touch screen 1 is a touch panel TP (Touch Panel, touch panel) touch screen.

In the present invention, the inner side 41 of the middle frame 4 of the mobile phone is set as a horizontal plane, and the gap between the inner side 41 and the touch screen 1 and the display screen 2 is sealed by caulking glue. Therefore, the narrow frame structure of the mobile phone is realized, the screen ratio is effectively increased, the entire mobile phone is more beautiful, and the user experience is improved. At the same time, the technical solution has a simple structure and is easy to assemble and realize.

Description of drawings

Other characteristics, objects and advantages of the present invention will become more apparent by reading the detailed description of non-limiting embodiments made with reference to the following drawings:

Fig. 1 is a cross-sectional structural schematic diagram of a narrow-frame mobile phone structure provided by a specific embodiment of the invention;

Fig. 2 is a schematic plan view of the structure of a narrow-frame mobile phone provided by a specific embodiment of the invention.

Detailed ways

The invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It can be understood that the specific implementation manners described here are only used to explain the invention rather than limit the invention. In addition, it should be noted that, for the convenience of description, only parts related to the present invention are shown in the drawings but not all content.

As shown in Figure 1, a mobile phone structure with a narrow frame includes: a touch screen 1, an LCM display screen 2, and a mobile phone middle frame 4 surrounding the touch screen 1 and the display screen 2, the inner side 41 of the mobile phone middle frame 4 is a horizontal plane, and the The gap between the inner surface 41 and the touch screen 1 and the display screen 2 is sealed by caulking glue.

In the mobile phone structure of this embodiment, the inner surface 41 of the mobile phone middle frame 4 is a horizontal plane. Compared with the prior art, this structure can realize that the mobile phone middle frame 4 is closely attached to the touch screen 1 and the LCM display screen 2, thereby realizing The purpose of reducing the width of the mobile phone frame. At the same time, the gap between the inner surface 41 and the touch screen 1 and the display screen 2 is sealed by caulking glue, which can further reduce the frame width of the mobile phone and prevent damage to the touch screen caused by domestic water or other liquids intruding into the gap. 41 and display screen 42 damage.

In this embodiment, the caulking glue is dripped into the gap between the inner surface 41 and the touch screen 1 and the display screen 2 by a glue dispenser, so as to seal the gap. Wherein, the caulking glue can use UV glue with good fluidity, silica gel, etc., and this is not limited.

In a preferred implementation of this embodiment, the width of the touch screen 1 is the same as that of the display screen 2. The advantage of this design is that the middle frame 4 of the mobile phone can be further closely attached to the touch screen 1 and the display screen 2. , reduce the gap between the inner surface 41 of the middle frame 4 of the mobile phone and the touch screen 1 and the display screen 2, so as to realize the design effect of a narrow frame to the greatest extent.

In another preferred implementation manner of this embodiment, the middle frame 4 of the mobile phone includes: ribs 42 , and the ribs 42 are used to support the display screen 2 and the touch screen 1 . Typically, the rib plate 42 is integrally formed with other parts of the mobile phone middle frame 4 . Wherein, the above structure can not only provide proper protection for the touch screen 1 and the display screen 2 , but also provide corresponding support for the touch screen 1 and the display screen 2 .

Of course, those skilled in the art can understand that, in addition to using the ribs 42 to support the display screen 2 and the touch screen 1 in the above mobile phone structure, an independent structure bracket can also be used to support the display screen 2 and the touch screen 1. The touch screen 1 is described above, but this embodiment does not limit it.

In another preferred implementation of this embodiment, the touch screen 1 and the display screen 2 can be bonded by OCA.

In another preferred implementation of this embodiment, the actual width of the rib 42 of the middle frame 4 of the mobile phone can be wider than the width of the touch screen 1 and the display screen 2, so as to reduce the difficulty of assembly. In addition, the outer surface of the middle frame 4 of the mobile phone 43 is preferably a smooth curved surface, so that the user can grasp the mobile phone.

In another preferred implementation of this embodiment, the display screen 2 is an LCM display screen, and the touch screen 1 is a TP touch screen.

The assembly process of the narrow frame mobile phone structure provided by the present invention is as follows:

(1), place the touch screen 1 and the display screen 2 horizontally in the space between the inner surface 41 of the middle frame 4 and the rib 42, and bond the touch screen 1 and the display screen 2 through OCA;

(2) Fix the touch screen 1, the display screen 2 and the black border area 44 at the upper end and the black border area 45 at the lower end of the middle frame 4 (the position of the above black border area is shown in FIG. 2 ) through foam glue or glue, and the touch screen 1 The gap with the inner side 41 of the middle frame 4 is sealed with caulking glue. Among them, UV glue with good fluidity, silicone glue, etc. can be used for the caulking glue, and the glue is applied to the surrounding gaps through the glue machine, and then the excess glue on the surface is wiped off.

Apparently, the above-mentioned embodiments of the present invention are only examples for clearly illustrating the present invention, rather than limiting the implementation of the present invention. For those of ordinary skill in the art, other changes or changes in different forms can be made on the basis of the above description. It is not necessary and impossible to exhaustively list all the implementation manners here. Any modification, equivalent replacement and improvement made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
