- At least one hollowed out region 100 is disposed on at least one side of the backing plate 10, and the film fixing structure 12 fixes the film 11 on the backing plate 10 through the hollowed out region 100.
- a plurality of hollow regions 100 may be disposed on at least one side of the back plate 10, and correspondingly, the bent portion 110 has a plurality of openings, and the plurality of film fixing structures 12 respectively pass through the Opening the hole and the hollowed out area, fixing the film 11 on the backboard 10; and further providing a plurality of hollowed out areas on each side of the backing plate, on each side of the backing plate,
- the film fixing structure 12 fixes the film 11 to the backing plate 10 of the side through the opening and the hollowed out region 100.
- the film fixing structure is a screw, the screw being located in a hollowed out region of the film, and the hollowed region is provided with a thread adapted to the screw.
- the bent portion of the film has a discontinuous phase crease line structure formed by pressing.
- the thickness of the film is greater than 0.3 mm, part of the material of the bent portion of the film is removed. If the thickness of the film is greater than 0.3 mm, part of the material of the bent portion 110 of the film may be removed, as shown in Fig. 7, the removed portion 112 of the film bent portion 110.
- the backlight module further includes: a plastic frame disposed between the back plate and the film.
