Of course, other types of display panels, such as an OLED (Organic Light-Emitting Diode) display panel, may be used, and the corresponding backlight module does not include a backlight source.
The application also discloses a backlight module 30, which is an improvement of the back plate 300 in the backlight module 30 and can be used for the display device 10, and for the backlight module 30, the application provides the following design:
fig. 2 is a schematic diagram of a backlight module according to an embodiment of the application, as shown in fig. 2, the backlight module 30 includes a back plate 300, the display panel 20 is disposed on the back plate 300, the back plate 300 includes a main body portion 310 and a bending portion 320, one end of the bending portion 320 is connected to an edge of the main body portion 310, the other end extends toward the direction of the display panel 20, the main body portion 310 has a rectangular structure, and the bending portion 320 is disposed around the main body portion 310 and surrounds the bending portion 320.

When the ratio of the length of the opening 400 to the length of the bending portion 320 is 1:2, the occupied area of the opening 400 on the bending portion 320 is smaller, the strength of the back plate 300 is higher, and deformation is not easy to occur under the condition of receiving larger external force; when the ratio of the length of the opening 400 to the length of the bending portion 320 is 1:8, the corresponding adhesive structure 500 that may be cut is long, and the detachment of the display panel 20 is easier.
Of course, the adhesive structure 500 may be a common glue, and the viscosity of the glue may be reduced by heating the glue at the opening 400, so that the display panel 20 is more easily detached from the backlight module 30. In addition to cutting and heating, the adhesive can be sprayed to the bonding structure through the opening 400, so that the adhesive is degummed more quickly.

At this time, the display panel 20 is connected to the back plate 300 through the heat sink 800, and the adhesive structure 500 is located between the heat sink 800 and the display panel 20.
For a display panel 20 of the type LCD (Liquid Crystal Display) for the display panel 20, the backlight module 30 further includes a lamp panel, an optical film, and a middle frame, which are sequentially stacked on the back plate 300. At this time, the display panel 20 is connected to the back plate 300 through the middle frame, and the adhesive structure 500 is located between the middle frame and the display panel 20.
The bonding structure 500 of the present application further comprises a flexible glue, which is bonded to the display panel 20, and because of the property of the flexible glue, the bonding structure 500 can be heated at the adhesive between the display panel 20 and the backlight module 30, and the heated Yi Lajiao can be easily removed by pulling, so that the bonding structure 500 can be removed from the display panel 20 more conveniently.
The main body 310 of the present application is rectangular, the bending parts 320 are disposed around the main body 310, and the plurality of openings 400 in each bending part 320 may be arranged in the same or different arrangement.
The following describes the opening 400 in the bending portion 320 corresponding to the main body 310, and the bonding structure 500 is a foam double sided adhesive tape.
Example 1:
fig. 3 is a schematic view of the openings of the first embodiment of the present application, and as shown in fig. 3, the back plate includes a plurality of openings 400, and the plurality of openings are not communicated. By providing the plurality of openings 400, the more the plurality of adhesive structures 500 are cut, the easier the positions of the cut adhesive structures 500 are, when the display panel 20 is removed later.
In addition, in this embodiment, the plurality of openings 400 are further divided into a plurality of first openings 410 and a plurality of second openings 420, the plurality of first openings 410 are on the same horizontal line, the plurality of second openings 420 are on the same horizontal line, and the connection line of the plurality of first openings 410 is not on the same line as the connection line of the plurality of second openings 420.
In short, the plurality of first openings 410 are located on the same horizontal plane, and the plurality of second openings 420 are located on the same horizontal plane, which corresponds to arranging the openings 400 in two rows, but it is also possible to arrange the openings 400 in three or more rows, and this embodiment is exemplified by two rows.
The distance between the horizontal line where the plurality of first openings 410 are located and the horizontal line where the plurality of second openings 420 are located is smaller than the thickness of the adhesive structure 500.
The number of openings 400 is further increased to sever more of the bonded structure 500 while ensuring the strength of the backplate 300.
Furthermore, the lengths of the first opening 410 and the second opening 420 may be equal, and the first opening 410 may be disposed between two adjacent second openings 420; the two ends of the first opening 410 are respectively overlapped with the adjacent two second openings 420.

Preferably, on the basis of the above, the intermittently arranged bonding structure 500 is adopted, specifically:
as shown in fig. 4, the bonding structure 500 includes a plurality of discontinuous foam segments 510, and a gap between two adjacent foam segments 510 corresponds to a position where the first opening 410 overlaps the second opening 420.
In this way, the adhesive structure 500 for fixing the display panel 20 can be completely cut, and after the adhesive structure 500 is completely cut, the display panel 20 can be directly removed without damaging the display panel 20.
Moreover, as shown in fig. 5, the bonding structure 500 further includes a plurality of precut holes 520, the plurality of precut holes 520 penetrate through the bonding structure 500 and are arranged in rows, the precut holes 520 are opposite to the opening 400, the plurality of precut holes 520 are arranged in rows to form a cutting path, and the length of the cutting path is equal to the length of the foam section 510.
When the cutting knife cuts the bonding structure 500, the bonding structure 500 is cut along the cutting path, so that the cutting knife can be prevented from shifting during cutting to scratch the display panel 20, and the bonding structure 500 is easier to cut by the cutting knife because the pre-cutting hole 520 penetrates through the bonding structure 500.
As shown in fig. 6, the backlight module 30 in this embodiment further includes a shielding structure 600, where the shielding structure 600 is made of a black opaque material, the shielding structure 600 is connected with the bending portion 320, the shielding structure 600 covers the opening 400, and the shielding structure 600 may be attached to the opening 400 of the bending portion 320 by using mylar (polyester film), and since mylar is black, the bending portion 320 is prevented from leaking light at the opening 400, and dust and water vapor outside can be prevented from entering the display device 10 from the opening 400, which causes display problems.
Of course, the opening 400 may be provided with a first soft rubber 710 and a second soft rubber 720, where the first soft rubber 710 and the second soft rubber 720 are respectively disposed at two opposite sides in the opening 400, and the first soft rubber 710 and the second soft rubber 720 are abutted against each other.
The cutting knife can extend into the display device 10 from the abutting position of the first soft rubber 710 and the second soft rubber 720, after the cutting foam is pulled out of the cutting knife, the first soft rubber 710 and the second soft rubber 720 recover to deform and are abutted again, and the opening 400 is sealed, so that repeated mylar sticking is not needed, and the cost is saved.
As shown in fig. 7, the back plate 300 in this embodiment further includes a limiting portion 330, and the main body portion 310, the bending portion 320, and the limiting portion 330 are integrally formed.
One end of the limiting part 330 is connected with the bending part 320, and the other end extends between the display panel 20 and the main body part 310; the opening 400 is located between the limit portion 330 and the body portion 310.
Therefore, even if a worker is not trained, the cutter can be easily operated under the guidance of the limiting part 330, the display panel 20 can not be scratched, the problem of breakage of the display panel 20 is caused, and the reworking efficiency is improved.
Example 2:
fig. 8 is a schematic view of an opening of a second embodiment of the present application, as shown in fig. 8, which differs from the first embodiment in that a plurality of openings 400 of the present embodiment are located on the same horizontal plane.
And, the gap between two adjacent foam segments 510 is greater than or equal to the gap between two adjacent openings 400, and the orthographic projection of the gap between two adjacent openings 400 overlaps with the orthographic projection of two adjacent foam segments 510.
