As shown in fig. 1 to 3, the applicant provides an exemplary technique that a first prism sheet 200 in an optical film 140 is extended and divided into a plurality of regions, so that the first prism sheet 200 can be bent to fix a light guide plate 112 and a reflective sheet 111, thereby eliminating a technical solution of a plastic frame and solving the technical problem of an excessively thick overall thickness of a backlight module 110. Specifically, a plurality of folding lines need to be designed on the first prism sheet 200, the first prism sheet 200 is bent according to the routing of the folding lines, and the first prism sheet 200 is bent to form an accommodating space for accommodating the light guide plate 112, the reflective sheet 111 and the like; the accommodating space is not closed, and the light guide plate 112, the reflective sheet 111, the second prism sheet 210, the diffusion sheet 113, and the like are not fixed to the first prism sheet 200.

As shown in fig. 4 to 6, the present application discloses a display device 100, which includes a display panel 120 and a backlight module 110 for providing backlight to the display panel. The backlight module 110 includes an optical film 140 such as a diffusion sheet 113, a prism sheet 114, and the like, and a light guide plate 112, a reflection sheet 111, an adhesive member 115, and a light source 116; the reflective sheet 111 is configured to reflect light; the light guide plate 112 is configured to guide a light direction; the diffusion sheet 113 is configured to scatter light; the prism sheet 114 is configured to increase light brightness; the prism sheet 114 includes a first prism sheet 200 and a second prism sheet 210, and the adhesive member 115 is used to fix the first prism sheet 200, the second prism sheet 210, the diffusion sheet 113, the light guide plate 112, and the reflection sheet 111 which are stacked.

Specifically, the light guide plate 112 is disposed on the reflective sheet 111; the diffusion sheet 113 is disposed on the light guide plate 112; the second prism sheet 210 is disposed on the diffusion sheet 113; the first prism sheet 200 is disposed on the second prism sheet 210; the adhesive member 115 is a single-sided adhesive 300, and the single-sided adhesive 300 laterally adheres the stacked reflective sheet 111, light guide plate 112, diffusion sheet 113, second prism sheet 210, and first prism sheet 200 to achieve a fixing effect; the light source 116 is disposed at one end of the light guide plate 112, and is disposed in a space formed by the single-sided adhesive 300, the diffusion sheet 113, the reflection sheet 111, and the light guide plate 112.

Of course, the stacking order of the first prism sheet 200, the second prism sheet 210, the diffusion sheet 113, the light guide plate 112, and the reflection sheet 111 is not fixed.

In the assembly process of the backlight module 110, the optical film, the light guide plate 112 and the reflective sheet 111 are important parts for adjusting the light emitted from the light source 116, and they need to be relatively fixed after being stacked together, otherwise the normal operation of the backlight module 110 is affected. The traditional rubber frame is thicker, which increases the thickness of the backlight module 110, and has complex assembly process and low assembly efficiency; although the exemplary technique can solve the problem of the overall thickness of the backlight module 110 being too thick, if the first prism sheet 200 is designed to be bent into a plurality of regions as shown in fig. 1 to 3, such steps are relatively complicated, and the light guide plate 112, the reflective sheet 111, and the diffusion sheet 113 are very easy to slide out of the accommodating space formed by the first prisms. In consideration of the fact that the optical film, the reflective sheet 111 and the light guide plate 112 are stacked and fixed and are easy to move after being stacked, the scheme adopts the single-sided adhesive 300 as the bonding member 115, and the adhesive surface of the single-sided adhesive 300 is bonded with the side surfaces of the stacked light guide plate 112, the reflective sheet 111 and the diffusion sheet 113, so that the function of fixing the light guide plate 112, the reflective sheet 111 and the diffusion sheet 113 can be achieved, and the light guide plate 112, the reflective sheet 111 and the diffusion sheet 113 are relatively fixed; meanwhile, the single-sided adhesive 300 has the characteristics of thin thickness, softness and easy folding, is easy to attach and rework, and can improve the installation efficiency of the backlight module 110.

Specifically, as shown in fig. 7 to 9, the single-sided adhesive 300 includes a first section 310, a second section 320, and a third section 330, and the first section 310, the second section 320, and the third section 330 are an integral structure; the first section 310 and the third section 330 are bonded with the reflective sheet 111, the light guide plate 112 and the optical film from the side, and the first section 310 and the third section 330 are arranged oppositely; the first section 310 and the third section 330 are both flush with the end surface of the first prism sheet 200; the second segment 320 is adhered to the bottom surface of the reflective sheet 111. The first section 310 and the third section 330 are adopted to bond the side surfaces of the reflecting sheet 111, the light guide plate 112 and the optical membrane in the stacking direction, so that the reflecting sheet 111, the light guide plate 112 and the optical membrane after stacking can be relatively fixed, the second section 320 is bonded with the bottom surface of the reflecting sheet 111, and the bonding stability of the second section 320 and the bottom surface of the reflecting sheet 111 is better because the bonding firmness and the bonding surface area are in direct proportion; the first section 310, the second section 320 and the third section 330 are of an integral structure, so that the second section 320 plays a role in supporting the bonding and fixing of the first section 310 and the third section 330, and meanwhile, the integral single-sided adhesive 300 has a good fixing effect on the reflector 111, the light guide plate 112 and the optical diaphragm.

Of course, the single-sided adhesive 300 may also be designed into multiple sections, and each section of the single-sided adhesive 300 is bonded at least to two adjacent ones of the reflective sheet 111, the light guide plate 112, the diffusion sheet 113, the first prism sheet 200, and the second prism sheet 210 from the side; the multiple sections of the single-sided adhesive 300 are not connected with each other. Like this can be more nimble use single face glue 300, avoid the bonding between every section to have the interference, be not continuous each other between the single face glue 300 moreover, make things convenient for solitary repair operation like this for material utilization is higher.

Specifically, as shown in fig. 10 and 11, the single-sided adhesive 300 includes a fourth segment 340 and a fifth segment 350; the light guide plate 112 includes a first portion 130 and a second portion 131, the first portion 130 is close to the light exit surface of the light guide plate, and the second portion 131 is close to the reflective sheet 111; the fourth segment 340 fixes the optical film 140 and the first portion 130 of the light guide plate by bonding from the side of the optical film; the fifth section 350 includes a first adhesive portion 351 and a second adhesive portion 352 connected to each other; the first adhesive part 351 adhesively fixes the reflective sheet 111 and the second part 131 of the light guide plate from the side surface of the reflective sheet; the second adhesive part 352 is adhered to the bottom surface of the reflective sheet 111; the fourth segment 340 and the fifth segment 350 are not connected to each other. Considering that the thickness of the light guide plate 112 is relatively thick, the single-sided adhesive 300 is designed into two sections, that is, the fourth section 340 and the fifth section 350, and then the fourth section 340 and the fifth section 350 are both bonded with partial areas of the light guide plate 112, so that the fixing firmness can be met, the material of the single-sided adhesive 300 can be relatively saved, and meanwhile, the single-sided adhesive 300 divided into two sections has flexible usability, and the backlight module 110 can be conveniently repaired.
