Fig. 3 is a schematic view of a first film layer structure of a backlight module according to an embodiment of the disclosure. As can be seen from fig. 1 to 3, in the backlight module, the middle frame is disposed on the light-emitting surface of the lamp panel, when the middle frame is fixed to the lamp panel, the hollow portion 300 of the middle frame corresponds to the light-emitting portion 100 of the lamp panel, and the light emitted by the light-emitting device 101 in the light-emitting portion 100 passes through the hollow portion 300 to provide backlight for the display panel. Meanwhile, the first edge 11, the second edge 12, the third edge 13, and the fourth edge 14 correspond to and contact with the first middle frame 21, the second middle frame 22, the third middle frame 23, and the fourth middle frame 24, respectively.
In the edge portion 200 of the lamp panel, at least one region forms a target edge portion, and the target edge portion may be a complete edge portion of any one of the four edge portions, i.e., the first edge portion 11, the second edge portion 12, the third edge portion 13, and the fourth edge portion 14, may be two, three, or all edge portions, or may be a partial region in a certain edge portion.

In the application, the target edge part and the target middle frame part are fixed through magnetic force, namely the target edge part and the target middle frame part are not attached through a glue layer or other materials, but the target edge part and the target middle frame part are made of materials, so that magnetic force is generated between the target edge part and the target middle frame part, and the target edge part and the target middle frame part are adsorbed together through the action of the magnetic force to achieve the fixing effect.
All be provided with the backplate in current backlight unit, the inside formation of backplate holds the chamber, fixes the lamp plate in the intracavity that holds of backplate earlier when the equipment, sets gradually center and other optical diaphragm in the direction of keeping away from the lamp plate again, forms complete backlight unit, forms complete display device with the laminating of display panel again. When the lamp panel is damaged, the display panel needs to be removed first, and then the optical film below the display panel needs to be removed, so that the lamp panel can be exposed and removed and replaced. The cost is higher regardless of the assembly or the replacement of the lamp panel. And in this application, cancelled the backplate, directly during the equipment through magnetic force with the lamp plate with the back of center together fixed, also only need during the change from the center back take off the lamp plate can, the technology is simpler relatively, the cost of equipment and change all obtains reducing. In addition, due to the fact that the back plate is omitted, the thickness of the whole backlight module is reduced, and the backlight module is more in line with the development trend of the current display field.
When the target intermediate frame portion and the target edge portion are fixed by a magnetic force, there are two types of arrangement of the materials of the target intermediate frame portion and the target edge portion.
In one embodiment, one of the target edge portion and the target middle frame portion is made of a ferromagnetic material, and the other is made of a magnet, that is, the target edge portion is made of a ferromagnetic material, and the target middle frame portion is made of a magnet, or the target edge portion is made of a magnet and the target middle frame portion is made of a ferromagnetic material. The ferromagnetic material includes metals such as iron, nickel, and cobalt, and the magnet has a property of attracting a ferromagnetic substance by generating a magnetic field by using atoms such as iron, cobalt, and nickel as components. Magnetic force is generated between the two different materials to fix the two materials.
In one embodiment, the material of the target edge portion and the target middle frame portion are both magnets, and the polarities of the contact areas of the two magnets are opposite. The target edge part and the target middle frame part are both magnets, one of the magnets is an N pole, the other magnet is an S pole in the contact area of the target edge part and the target middle frame part, and the target edge part and the target middle frame part are fixed through the principle that the magnets attract each other in opposite directions. Under the same condition, the magnetic force between the magnet and the magnet is larger than that between the magnet and the ferromagnetic material, so that the fixing effect of the edge part and the middle frame part of the target is better by adopting two magnets with different polarities.
In one embodiment, the middle frame portion comprises at least one target middle frame portion group, and the target middle frame portion group comprises two target middle frame portions which are oppositely arranged on two sides of the hollow portion.

Similarly, when part or all of the area of the second middle frame portion 22 forms one target middle frame portion and part or all of the area of the fourth middle frame portion 24 forms another target middle frame portion, the two target middle frame portions also form one target middle frame portion group together; in correspondence with the target middle frame portion group, a part or the whole area of the third edge portion 13 forms one target edge portion, and a part or the whole area of the fourth edge portion 14 forms another target edge portion, and these two target edge portions also form one target edge portion group together.
The middle frame part may include only one target middle frame part group and one corresponding target edge part group, or may include two target middle frame part groups and two corresponding target edge part groups at the same time. Because every target center group includes two target center, this both sides all can produce magnetic force and make lamp plate and center fix, and because two target center set up respectively in the relative both sides of fretwork portion 300 for two magnetic force distribution are comparatively balanced and even, and then the fixed effect of lamp plate and center is better.
In one embodiment, the middle frame part comprises a middle frame part protrusion on the inner wall of the middle frame part body, the outer wall of the edge part is contacted with the inner wall of the middle frame part body, and the top surface of the edge part is contacted with the bottom surface of the middle frame part protrusion.
