The embodiments described below with reference to the drawings are exemplary only for the purpose of explaining the present application and are not to be construed as limiting the present application.

At present, with the rapid development of smart phones, self-luminous OLED (Organic Light Emitting Display) screens have good Display performance, the OLED Display technology is different from the traditional LCD (Liquid Crystal Display) Display mode, a backlight is not needed, a very thin Organic material coating and a glass substrate are adopted, and when current flows, the Organic materials can emit Light. Moreover, the OLED display screen can be made lighter and thinner, the visual angle is larger, and the power consumption can be obviously saved, so that the smart phone mostly adopts the large-size OLED screen to improve the use experience of users.

Wherein, part smart mobile phone adopts the curved surface screen, and the curved surface screen is a display screen that adopts flexible plastics, mainly realizes through the OLED panel at present. Compared with a straight screen, the curved screen has better elasticity and is not easy to break.

The display module 20 of the present application is preferably an OLED screen, among others.

An electronic device 100 according to an embodiment of the application is described below with reference to fig. 1-2. The electronic device 100 according to the embodiment of the present application includes: a housing 10 and a display assembly 20.

Referring to fig. 2, the housing 10 has a first surface 11 and a second surface 12 adjacent to each other, the first surface 11 having a first groove 111, and the second surface 12 having a second groove 121 communicating with the first groove 111. The display assembly 20 is disposed on the housing 10, and the display assembly 20 includes a main body section 21, a bending section 22 and an extending section 23 connected in sequence, the main body section 21 and the extending section 23 are stacked, the extending section 23 is located between the main body section 21 and the first surface 11, the extending section 23 is embedded in the first groove 111, the bending section 22 is located in the second groove 121, and a spot glue layer 33 is disposed between the bending section 22 and an inner wall of the second groove 121.

Wherein, the display assembly 20 of the present application is a curved structure, since the display assembly 20 is connected and matched with the housing 10, and the edge of the display assembly 20 has the bending section 22 and the extending section 23, in the display assembly 20, the thickness of the bending section 22 and the extending section 23 at the position is greater than the thickness of other positions, that is, since the main body section 21 and the extending section 23 are stacked, the stacking thickness of the electronic device 100 is increased. From this, need to set up first cell body 111 and second cell body 121 in casing 10, first cell body 111 can be used for arranging extension 23, and second cell body 121 can be used for arranging kink 22 to can guarantee that display module 20 is smooth transition on casing 10, guarantee display module 20's display effect.

Further, since the second groove 121 is used to arrange the bent section 22 while the housing 10 has a reliable structural strength, the bent section 22 is not in direct contact with the housing 10. It will be appreciated that when the bent segment 22 is in contact with the housing 10 without protective measures, the bent segment 22 will be at risk of damage, thereby affecting the display effect of the display assembly 20. Certain clearance is left between second cell body 121 and the bending segment 22 of this application, is provided with some glue film 33 in bending segment 22 and second cell body 121's clearance department moreover, and some glue film 33 can play good fixed action to bending segment 22 to can promote the reliability of display module 20 in bending segment 22 department.

Specifically, the dispensing layer 33 is disposed in the gap between the bending section 22 and the second groove 121, and the dispensing layer 33 may be a gap filling glue with a soft texture, so that the dispensing layer 33 may serve to buffer the vibration transmission between the display assembly 20 and the housing 10. When electronic equipment 100 falls, take place the striking between display module 20 and the object, the vibration of buckle segment 22 department will transmit to casing 10 through some glue film 33, because some glue film 33 is soft in texture, has good absorption vibration's effect from this to can play good buffering effect, reduce the risk that display module 20 damaged, promote electronic equipment 100's reliability.

Meanwhile, because the spot glue layer 33 is arranged between the shell 10 and the display component 20, the reserved depth of the second groove body 121 does not need to be too large, the concave depth of the second groove body 121 can be reasonably reduced according to design requirements, and the gap between the inner wall of the second groove body 121 and the bending section 22 is reduced. It will be further understood that the structural strength of the shell 10 is one of the important parameters in the development process of the shell 10, and the structural strength of the shell 10 is usually adjusted by adjusting the thickness of the shell 10, and when the material of each part of the shell 10 is consistent, the structural strength of the shell 10 at the thicker part is high.

Compared with the arrangement mode that a certain gap is reserved between the second groove body 121 and the bent section 22, the arrangement mode that the spot gluing layer 33 is arranged between the second groove body 121 and the bent section 22 can reduce the depth of the second groove body 121. Thereby, the thickness of the case 10 provided with the dispensing layer 33 is thinner than the thickness of the case 10 not provided with the dispensing layer 33, while ensuring the thickness of the case 10 at the second groove 121 to be uniform. And then set up adhesive tape 33 through the inner wall at second cell body 121 and between kink 22 can be under the prerequisite of guaranteeing casing 10 structural strength, rationally reduce casing 10's thickness to satisfy the frivolous design demand of electronic equipment 100.

According to electronic equipment 100 of this application embodiment, through be provided with some glue films 33 between second cell body 121 and bending segment 22, some glue films 33 can play good fixed action to bending segment 22, have the effect of buffering vibration simultaneously to can promote the reliability of bending segment 22 department, can rationally reduce the thickness of casing 10 simultaneously, satisfy the lightweight design demand of electronic equipment 100.

As shown in fig. 2, the depth of the second groove 121 gradually decreases in the direction from the bent section 22 to the extended section 23. Thus, it is possible to prevent the structural strength of the housing 10 from being affected by an excessively large recessed depth of the second groove 121.

Specifically, referring to fig. 2, since the display module 20 includes the bending section 22, the display module 20 is bent toward the housing 10, the extending section 23 is a straight section, and the extending section 23 is connected to the bending section 22, and the bending curvature of the bending section 22 is gradually reduced in the direction from the bending section 22 to the extending section 23. The second groove body 121 is used for being matched with the bent section 22, the depth of the second groove body 121 is gradually reduced, so that the second groove body 121 is matched with the bent section 22, gaps between the first groove body 111 and the second groove body 121 and the display assembly 20 are effectively prevented from being too large, and therefore the structural strength of the position where the first groove body 111 and the second groove body 121 are arranged on the shell 10 is guaranteed.

As shown in fig. 2, the surface of the bent section 22 facing the inner wall surface of the second groove 121 is a cylindrical surface, so that the transition of the bent section 22 is smoother. It can be understood that the cylindrical surface transition mode can prevent the problem of stress concentration at a certain position of the bending section 22 due to an excessively large bending angle of the bending section 22, so as to improve the reliability at the bending section 22, and the cylindrical surface transition mode can enable the display module 20 to transition from the bending section 22 to the extending section 23 with a short bending distance, thereby effectively saving the space occupied by the bending section 22.

As shown in fig. 2, a first adhesive layer 31 is provided between the extension segment 23 and the main body segment 21, and the extension segment 23 and the main body segment 21 can be adhesively fixed by the first adhesive layer 31, so that the extension segment 23 is well fixed, the reliability of the display assembly 20 is improved, and the display assembly 20 is convenient to be matched with the housing 10.

It can be understood that the extension segment 23 and the main body segment 21 are bonded and fixed, so that the extension segment 23 can be well restrained, and when the housing 10 is matched with the display assembly 20, the extension segment 23 is prevented from contacting the first groove 111, thereby facilitating the arrangement of the extension segment 23 in the first groove 111.

The electronic device 100 according to the embodiment of the present application further includes a cover plate 40. Referring to fig. 2, the cover plate 40 is disposed on a side surface of the main body section 21 away from the housing 10, a part of an edge of the cover plate 40 extends beyond the display module 20, and the cover plate 40 is embedded in the housing 10. Thus, the display module 20 is disposed between the cover plate 40 and the housing 10, and the cover plate 40 can provide good protection for the display module 20.

Specifically, the cover plate 40 is required to shield the display assembly 20 in consideration of structural strength of the display assembly 20, so as to prevent the display assembly 20 from being directly exposed to the external environment, and to protect the display assembly 20 well through the cover plate 40.

The cover plate 40 may be a glass cover plate, and the cover plate 40 may also be a sapphire cover plate. The glass cover plate and the sapphire cover plate have high structural strength, high reliability and good light transmission.

Further, a second adhesive layer 32 is arranged between the cover plate 40 and the main body section 21, the cover plate 40 and the main body section 21 can be bonded and fixed through the second adhesive layer 32, the cover plate 40 has high structural strength, the reliability of the display assembly 20 can be improved through the bonding and fixing mode with the cover plate 40, and meanwhile, the display effect of the display assembly 20 can be guaranteed.

It is understood that the cover plate 40 is fixed to the display assembly 20 to prevent the display assembly 20 from moving relative to the cover plate 40 to affect the user experience when the user views the display content of the display assembly 20 through the cover plate 40.

The second adhesive layer 32 is an optical adhesive layer, which is formed by coating optical adhesive and has the properties of being colorless and transparent, high in light transmittance, and good in adhesive strength.

Optionally, the second Adhesive layer 32 is an OCA (Optically Clear Adhesive), the OCA is a double-sided Adhesive tape without a base material, which is obtained by making an optical acrylic Adhesive into a non-base material and then respectively attaching a release film to the upper and lower bottom layers, so as to ensure the bonding effect between the cover plate 40 and the display module 20.

As shown in fig. 2, the first surface 11 and the second surface 12 are smoothly transitioned to facilitate machining at the first surface 11 and the second surface 12, and to facilitate mating of the display assembly 20 with the first surface 11 and the second surface 12.

As shown in fig. 2, the depth of the second groove 121 is D, and D satisfies the parameter range: 0.2mm-0.25 mm. When D satisfies the above parameter range, the depth of the second groove 121 is shallow, and the requirement of the second groove 121 matching with the bending section 22 can be satisfied, that is, the second groove 121 and the bending section 22 are fixed by the spot adhesive layer 33, so that the thickness of the casing 10 can be reasonably reduced on the premise of ensuring the structural strength of the casing 10 at the second groove 121, and the light and thin design requirement of the electronic device 100 can be satisfied.
