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.
Referring to fig. 2, the present embodiment provides a mobile terminal, including a display screen module 10 and a main structure 20, where the display screen module 10 includes a display layer 11 and a transparent cover 12 stacked on the display layer 11, the display layer 11 is disposed on the main structure 20, the mobile terminal further includes a gasket 30, the gasket 30 is an annular body, referring to fig. 3, the gasket 30 includes a first plane 31, a second plane 32, and an inclined plane 33, the first plane 31 is connected with the transparent cover 12, the inclined plane 33 is connected with the main structure 20, and the second plane 32 faces the display layer 11.
Referring to fig. 4, the gasket 30 is a closed annular body having a right triangle cross-section, further incorporating the cross-sectional view of the gasket 30 shown in fig. 3. Correspondingly, the washer 30 comprises three annular surfaces, respectively a first flat surface 31 on the upper side, a second flat surface 32 on the inner side, and a bevel 33 on the outer side. The upper side refers to the side facing the light-transmitting cover plate, the inner side refers to the side facing the display layer, and the outer side refers to the side facing the main structural member.
The shape of the first plane 31 matches the shape enclosed by the edges of the transparent cover 12 of the display module 10. For example, the edge of the transparent cover plate 12 of the display screen module 10 encloses a square ring, and the ring surface where the first plane 31 is located corresponds to the square ring, so that after the edge of the transparent cover plate 12 contacts and is connected with the first plane 31, the edge of the transparent cover plate 12 is uniformly stressed with the first plane 31 everywhere, so that the display screen module 10 is stably connected with the gasket 30, and the firmness of the display screen module 10 is improved. The contact area between the first plane 31 and the transparent cover plate 12 may be a screen frame, and the screen frame surrounds the display area and is not used for displaying, so as to avoid the shielding effect on the display due to the connection between the transparent cover plate 12 and the gasket 30. Preferably, the width of the first plane 31 can be set small enough to form an ultra-narrow, extremely narrow bezel of the screen, or a full screen.
In addition, the contact surface of the connection between the gasket 30 and the main structure 20 is designed to be an inclined surface, and compared with a right-angled surface, the contact area between the gasket 30 and the main structure 20 can be increased, so that the firmness of the display screen module 10 is further improved.
Furthermore, the surface facing the display layer 11 is designed to be a plane, so that the gasket 30 is prevented from occupying the installation space of the display layer 11 while the firmness of the display screen module 10 is ensured, the gasket 30 is prevented from causing interference effects such as touch on the display layer 11, and the display performance of the terminal is ensured.
In the mobile terminal according to the embodiment of the present invention, a gasket 30 is added between the display screen module 10 and the main structure 20, the gasket 30 is an annular body, and the annular body includes three surfaces, namely an annular first plane 31, an annular second plane 32 and an annular inclined plane 33. The first plane 31 is used for connecting the transparent cover plate 12 of the display screen module 10, and the width of the first plane 31 can be designed to be small enough to ensure that the screen frame formed on the transparent cover plate 12 is extremely narrow; meanwhile, the inclined plane 33 is used for connecting the main structure 20, and the design of the inclined plane 33 can ensure that the contact area between the display screen module 10 and the main structure 20 is large enough; the second plane 32 faces the display layer 11 and prevents the gasket 30 from touching the display layer 11. It can be seen that, in this embodiment, when the narrow frame of the screen is realized, firm connection between the display screen module 10 and the main structure 20 is ensured, the probability of screen crack, water inflow and the like is reduced, and the quality of the terminal is improved.
Referring to fig. 5, in the embodiment of the present invention, the gasket 30 is a wedge-shaped annular body including only one annular surface, i.e., the first plane 31, for connecting with the light-transmissive cover plate 12. The opposite annular surface has no surface and is only an annular ring, and the design can also reduce the volume of the gasket 30 as much as possible under the condition of ensuring the stable connection between the display screen module 10 and the main structure 20 so as to reduce the space occupied by the gasket 30 in the terminal, simplify the internal structure of the terminal on one hand, and avoid the influence of the gasket 30 on other structures in the terminal on the other hand.
