The backlight unit 10 is sequentially disposed above the upper case 40 (in a direction away from the upper surface of the upper case 40), a light exit surface of the backlight unit 10 is disposed above the backlight unit 10, and the display panel 20 is disposed on the light exit surface. In a specific arrangement, the backlight assembly 10 covers the upper surface of the upper case 40, and the display panel 20 is disposed above the backlight assembly 10.
The backlight assembly 10 includes a backlight support 11, a light source, a light guide plate, and an optical film disposed above the light guide plate.
The backlight bracket 11 is used for supporting the light source in the backlight assembly 10, and a light guide plate for homogenizing the light emitted from the light source, and the light guide plate is covered with a plurality of layers of films for improving the light; the display panel 20 is disposed on the light emitting surface of the backlight unit 10, and the display panel 20 is covered by a glass cover plate 30, and the glass cover plate 30 is bonded to the upper surface of the sidewall 111 of the backlight bracket 11. The backlight holder 11 is disposed on the upper surface of the upper case 40.
In a specific arrangement, reference is also made to fig. 4, fig. 5, fig. 6, and fig. 7, where fig. 5 is a partially enlarged view of a portion C in fig. 4, and fig. 6 and fig. 7 are schematic structural diagrams of different backlight brackets. Referring to fig. 5 to 7 together, a step structure 111 is disposed inside a sidewall 112 of the backlight bracket 11 provided in this embodiment, and the step structure 111 is used for supporting the display panel 20, so as to fix the display panel 20.
In a specific arrangement, as shown in fig. 6, the stepped structure 111 includes a vertical surface 1111 recessed inward of the side wall 112, and a stepped surface 1112, the vertical surface 1111 of the stepped structure surrounding a space for accommodating the display panel 20, the stepped surface 1112 of the stepped structure 111 forming a plane for supporting the display panel 20. As shown in fig. 6 and 7, the backlight bracket 11 provided in the present embodiment is a rectangular structure, wherein a stepped structure 111 is disposed on an inner side of four sidewalls 112 of the backlight bracket 11, or two opposite sidewalls 112 of the backlight bracket 11 are higher than the other two opposite sidewalls 112, and a stepped structure 111 is disposed on an inner side of the two opposite sidewalls 112 with a higher height. The display panel 20 is fixed by different backlight holder 11 structures. Specifically, as shown in fig. 6, fig. 6 shows that the four sidewalls 112 of the backlight bracket 11 have the same height, and at this time, a consecutive step structure 111 is formed by hollowing inside of the four sidewalls 112 for accommodating the display panel 20, or as shown in fig. 7, two opposite sidewalls 112 of the four sidewalls 112 of the backlight bracket 11 are higher and two opposite sidewalls 112 are lower, and the step structure 111 is formed by hollowing on the two opposite sidewalls 112 higher. When the glass cover 30 is fixed, the glass cover 30 is bonded to each of the four side walls 112 in the backlight holder 11 configured as shown in fig. 6. In the configuration of the backlight holder 11 shown in fig. 7, the glass cover 30 is adhesively attached to the two opposite side walls 112 having a greater height.
As shown in fig. 5 and 6, in order to match the stepped structure 111 on the backlight holder 11, the side wall of the display panel 20 is provided with protrusions 21 extending to both sides, the protrusions 21 are overlapped on the stepped surface 1112 of the stepped structure 111, and when the backlight holder 11 is configured as shown in fig. 6, a circle of protrusions 21 is circumferentially provided on the side wall of the display panel 20, and the protrusions 21 are overlapped on the stepped surface 1112 of the backlight holder 11 and fixedly connected, thereby realizing the fixation between the backlight holder 11 and the display panel 20. When the backlight holder has the structure shown in fig. 7, two opposite sidewalls of the display panel 20 are respectively provided with a protrusion 21.
When the display panel 20 is specifically arranged, in order to avoid interference, the light emitting surface of the display panel 20 is not higher than the bonding surface between the backlight bracket 11 and the glass cover plate 30, that is, the upper surface of the display panel 20 is lower than the upper surface of the side wall of the backlight bracket 11, so that the glass cover plate 30 is not squeezed to the display panel 20 when being installed, and the safety of the display panel 20 is ensured. In a specific embodiment, the light emitting surface of the display panel 20 is equal to the upper surface of the sidewall of the backlight bracket 11.
In the above-mentioned solution, the backlight bracket 11 of the backlight assembly 10 is used to fix the glass cover 30, and therefore, as shown in fig. 6 and 7, the sidewall 112 of the backlight bracket 11 should have a certain width to ensure that the glue coated on the backlight bracket 11 can be firmly adhered to the display panel 20. In a specific arrangement, as shown in fig. 5, the upper surface area of the sidewall of the backlight holder 11 (the upper surface of the sidewall 112 is the surface of the sidewall 112 contacting the glass cover 40) is an adhesion area 12, and the width of the adhesion area 12 is a width f shown in fig. 5, and the width is 0.3mm to 0.5 mm. Such as 0.3mm, 0.4mm, 0.5mm, and the like, which is between 0.3mm and 0.5mm, that is, the bonding widths of the left and right sides of the glass cover plate 30 and the upper surface of the sidewall 112 of the backlight bracket 11 are both between 0.3mm and 0.5 mm. In a specific bonding process, the bonding between the backlight bracket 11 and the glass cover plate 30 can be realized by different materials, specifically, for example, the glass cover plate 30 is bonded and connected to the upper surface of the sidewall 112 of the backlight bracket 11 by dispensing or foam adhesive. When dispensing is used, the bonding area 12 can be made narrower, for example, the width of the bonding area 12 is between 0.2mm and 0.3mm, and when foam cotton is used, the bonding area 12 is made larger, for example, between 0.3mm and 0.5 mm. The glass cover plate 30 and the backlight holder 11 can be stably connected by using the glue of the above type.
In addition, to ensure the integrity of the appearance, the glass cover 30 is provided in the present application with the side walls of the glass cover 30 positioned within the housing 50 to ensure the integrity of the front panel side of the mobile terminal. When the above solution is adopted, as shown in fig. 4, the upper casing 40 provided in this embodiment is located in the outer casing 50, the upper surface of the upper casing 40 is a complete plane, and the backlight unit 10 is directly disposed on the upper casing 40, for example, the backlight unit 10 may be adhered and fixed on the casing 40. The side wall of the backlight holder 11 of the backlight unit 10 is in direct contact with the outer case 50, and when the glass cover 30 is specifically set, it is fixed by the backlight holder 11, that is, the bonding region between the glass cover 30 and the backlight unit 10 is set on the backlight holder 11.
It can be seen from the above structure that the backlight source bracket 11 is directly bonded and fixed with the glass cover plate 20, so that the bonding width between the upper case 4 and the glass cover plate 3 in fig. 1 in the prior art is saved, and on the premise that the width of the display panel 2 is not changed, the screen occupation ratio (the screen occupation ratio is equal to the display screen area/the front panel area of the mobile terminal) is improved, and the width of the frame of the mobile terminal is reduced due to the narrowing of the non-display area.
In order to show the difference between the mobile terminal in the present application and the mobile terminal in the prior art in terms of the frame width, taking the structures shown in fig. 2 and fig. 4 as examples, the mobile terminal in the prior art is compared with the frame of the mobile terminal provided in the embodiment of the present application. Here, the part of the glass cover plate 3 extending to the outside of the backlight unit 5 shown in fig. 1 overlaps the upper case 4 of the mobile terminal, and at this time, the frame width of the mobile terminal is D1: the housing sidewall width a + the upper housing sidewall width b + the bonding region width c + the non-display region width D of the display panel, i.e., D1 ═ a + b + c + D. As can be seen from fig. 1, in the structure shown in fig. 1, the glass cover plate 3 is adhesively connected to the upper case 4 of the mobile terminal, i.e., the adhesive region is provided on the upper case, so that the glass cover plate 3 needs to have a sufficient width as the adhesive region, and in particular, the width c of the adhesive region is approximately 0.9mm in order to ensure the adhesive strength, thereby ensuring the reliability of the adhesion. Therefore, in order to ensure the connection strength of the mobile terminal in the prior art, the frame has a larger frame width.
In the structure shown in fig. 4 and 5 of the present application, the glass cover 30 is bonded to the backlight bracket 11, the upper casing 40 is accommodated in the outer casing 50 and disposed below the backlight assembly 10, and the upper casing 40 does not occupy the bonding width of the glass cover 30, so in this embodiment, the frame width of the mobile terminal is D2: the housing sidewall width a + the bonding region width f + the non-display region width D of the display panel, i.e., D2 ═ a + f + D. As can be seen from comparing fig. 2 and fig. 4, the bonding width c of the display panel and the upper case in the prior art is 0.9mm, and the sidewall 41 of the upper case 4 in the prior art also occupies a certain width b, and the bonding width f of the display panel 40 and the backlight bracket 11 in the present application is 0.2mm to 0.5mm, so that it can be seen that the frame width of the mobile terminal provided in the embodiment of the present application is significantly smaller than the frame width of the mobile terminal in the prior art, thereby reducing the width of the non-display area, and when the size of the display panel is not changed, the width of the display area is correspondingly increased, and therefore, the screen occupation ratio of the mobile terminal provided in the present embodiment is significantly increased, wherein the screen occupation ratio is the display area/the front panel area of the mobile terminal, and the width of the frame of the mobile terminal is reduced.
In addition, in order to improve the stability of the glass cover plate 30, as shown in fig. 8, in another specific embodiment, the upper case 40 further includes boss structures 42 respectively disposed on the upper and lower sides of the upper surface, a recessed space 43 for accommodating the backlight assembly is formed between the two boss structures 42, the recessed space is the upper surface of the upper case, and the upper and lower sides of the glass cover plate 30 are respectively bonded to the two boss structures 42 of the upper case 40. Referring to fig. 4, in a specific arrangement, the backlight assembly 10 is disposed in the recessed space 43 of the upper casing 40, the backlight bracket 11 is located between two inner sidewalls of the two boss structures 42, when the backlight assembly is fixed to the glass cover 30, the left and right sides of the glass cover 30 are bonded to two sidewalls 112 of the backlight bracket 11, and the upper and lower sides of the glass cover 30 are bonded to the two boss structures 42, respectively. In specific arrangement, the upper and lower edges of the glass cover plate 30 are respectively bonded to the two boss structures 42 by dispensing. Thereby increasing the bonding area of the glass cover plate 30 and further ensuring the stability of the glass cover plate 30. And in order to ensure the bonding effect, the bonding surface of the two boss structures 42 of the upper shell 40 and the glass cover plate 30 is flush with the bonding surface on the backlight bracket 11, so that the four edges of the glass cover plate 30 can be bonded firmly at the same time.
During specific setting, the upper and lower sides of the glass cover plate 30 correspond to the upper and lower sides of the mobile terminal, and the upper and lower sides of the mobile terminal need to be provided with some devices, such as keys, cameras, light compensating lamps, receivers and other structures, so that the upper and lower sides of the mobile terminal have sufficient width regions as bonding regions with the glass cover plate 30, thereby improving the bonding effect of the glass cover plate 30 and improving the stability of the glass cover plate 30.
Further, in the structure provided in the above example, the glass cover 30 is fixed due to adhesion between the glass cover 30 and the backlight holder 11. And the backlight source support 11 is located inside the casing 50, therefore, when glue is coated, the glue between the glass cover plate 30 and the backlight source support 11 cannot overflow outside the casing 50, that is, the influence on the appearance of the mobile terminal caused by glue overflow during assembly is avoided. When the above structure is adopted, since the case of the flash is not considered, a sufficient amount of glue may be applied to the bonding region 12 to secure the bonding strength of the glass cover plate 30. Compared with the mode of bonding the glass cover plate and the shell in the prior art, the bonding mode adopted in the prior art needs to consider the condition of glue overflow, so that less glue is often coated during bonding, or a bonding area which is wide enough is needed to be arranged to avoid the condition of glue overflow. In the present application, the above problem need not be considered, and even if glue overflow occurs, the glue is located inside the housing 50, which does not affect the appearance of the mobile terminal, thereby reducing the processing requirement when the glue is applied, and improving the yield in production.
In a specific embodiment, in order to further improve the bonding effect and avoid the occurrence of glue overflow, it is preferable that the overlapping surface of the outer casing 50 and the glass cover plate 30 is higher than the bonding surface of the backlight bracket 11. Thereby guaranteed when the overlap joint, have sufficient space between backlight support 11 and the glass apron 30 and hold glue, improved the thickness of glue, improved the volume of glue promptly to guaranteed glass apron 30 and between the bonding strength, and, because the top surface of shell 50 lateral wall is higher than the top surface of backlight support 11 lateral wall, consequently, glue can be blocked by shell 50 when excessive, thereby avoided the condition of excessive glue, improved the condition that appears overflowing gluing.
The embodiment of the present application further provides a mobile terminal including the frame structure in any one of the situations described in the foregoing embodiments, where the mobile terminal may be, for example, a mobile phone, a tablet computer, a palmtop computer, and the like.
It will be apparent to those skilled in the art that various changes and modifications may be made in the embodiments of the present application without departing from the spirit and scope of the application. Thus, if such modifications and variations of the embodiments of the present application fall within the scope of the claims of the present application and their equivalents, the present application is also intended to encompass such modifications and variations.
