The plurality of light beads 22 may be arranged at intervals, for example, in an array on the light panel 21, so as to achieve uniform light emission in different areas of the display device 20. The distance between the beads 22 may be set as desired, and is not particularly limited herein.
The transparent packaging adhesive 23 is disposed on the lamp panel 21 and covers the plurality of lamp beads 22. The surface of the transparent encapsulation compound 23 facing away from the lamp panel 21 is a flat surface in order to arrange the layer structure of the display device 20. The transparent packaging adhesive 23 is made of a transparent material to improve the light emitting efficiency of the lamp beads 22, and the material of the transparent packaging adhesive 23 can be a light diffusion material to replace a diffusion plate so as to realize light diffusion and improve the diffusion efficiency of the backlight source.

In the embodiment of the present application, the preset distance between the display screen 25 and the optical film layer 24 is in the range of 4 mm to 8 mm, for example, the preset distance of 6 mm can be selected, so that the optical film layer 24 and the display screen 25 can be isolated without increasing the thickness of the display device 20; in addition, since the diffusion plate and the support columns are omitted and the transparent encapsulation adhesive 23 is used to encapsulate the lamp beads 22 and fix the optical film 24, the thickness of the display device 20 can be reduced, and thus, the thickness of the whole display device 20 is not affected by the preset distance between the display screen 25 and the optical film 24, and the thickness of the display device 20 is reduced, which is beneficial to the light and thin appearance of the display device 20.
It should be noted that, the projection of the display screen 25 on the optical film 24 covers the optical film 24, that is, the area of the display screen 25 is larger than the area of the optical film 24, which is determined by the setting position of the optical film 24, and the portion of the display screen 25 beyond the optical film 24 can be used as a routing area of the display screen 25, so that the display effect of the display screen 25 is not affected.
Illustratively, the display device 20 further includes a back plate 26, the back plate 26 for carrying electrical devices in the display device 20.

The first side plate 261 is connected with the bottom plate 260 in a bending manner, for example, the first side plate 261 and the bottom plate 260 may be 90 ° therebetween, i.e. vertically disposed. The first side plate 261 can be arranged at the periphery of the bottom plate 260, the first side plate 261 and the bottom plate 260 are surrounded to form a containing groove 264, and the lamp panel 21, the transparent packaging adhesive 23 and the optical film layer 24 are arranged in the containing groove 264 so as to fix the lamp panel 21, the lamp beads 22, the transparent packaging adhesive 23 and the optical film layer 24, thereby reducing the reduction of the backlight display effect caused by shaking of the lamp panel 21, the lamp beads 22, the transparent packaging adhesive 23 and the optical film layer 24.
Wherein, lamp plate 21, transparent encapsulation glues 23 and optical film layer 24 are square, and the periphery of lamp plate 21, transparent encapsulation glues 23 periphery and optical film layer 24's periphery respectively with first side plate 261 butt, also first side plate 261 can follow the horizontal direction and carry out spacingly to lamp plate 21, transparent encapsulation glues 23 and optical film layer 24 promptly, reduces the rocking of lamp plate 21, transparent encapsulation glues 23 and optical film layer 24 to can reduce the influence of peeling off between the layer to the display effect.
The display device 20 further includes a reflective film 27, where the reflective film 27 is attached to the first side plate 261, and the reflective film 27 is used for reflecting light emitted by the lamp beads 22 laterally, so as to reduce waste of the light source. The peripheral edge of the optical film layer 24, the peripheral edge of the transparent sealing compound 23, and the peripheral edge of the lamp panel 21 are respectively abutted against the reflective film 27, so that the reflective film 27 can be fixed.
Illustratively, the surface of the optical film 24 facing away from the bottom plate 260 is flush with the surface of the first side plate 261 facing away from the bottom plate 260 to facilitate positioning and limiting of the optical film 24; or the surface of the first side plate 261 facing away from the bottom plate 260 is slightly higher than the surface of the optical film layer 24 facing away from the bottom plate 260, the occurrence of warping of the edge of the optical film layer 24 can be reduced.

The third side plate 263 has a height smaller than that of the first side plate 261, and since the third side plate 263 needs to limit the left and right shaking of the display screen 25, the first side plate 261 needs to limit the optical film layer 24, the transparent packaging adhesive 23 and the lamp panel 21, and the thicknesses of the optical film layer 24, the transparent packaging adhesive 23 and the lamp panel 21 are larger than that of the display screen 25, and therefore, the height of the first side plate 261 is larger than that of the third side plate 263.
Illustratively, the display device 20 further includes an adhesive 29, the adhesive 29 being disposed between the optical film 24 and the transparent encapsulant 23 to adhere the optical film 24 to the transparent encapsulant 23. It can be understood that the transparent packaging adhesive 23 mainly encapsulates the lamp beads 22, and the viscosity of the transparent packaging adhesive 23 is smaller, so that the adhesive 29 is provided for bonding, and the firmness of fixing the optical film layer 24 can be improved. Wherein, the thickness of the laminating adhesive 29 is smaller than that of the transparent packaging adhesive 23, so as to reduce the waste of materials and save materials.

The plurality of first ink portions 210 are disposed between the adhesive 29 and the optical film 24, and each of the first ink portions 210 is disposed corresponding to one of the light beads 22, so as to scatter the light emitted from the light beads 22 or reduce the strong light, thereby improving the uniformity of the light source. For example, the first ink part 210 may be white and have a silk-screen shape to achieve the effect of diffusing light. The second ink layer 211 is disposed between the transparent packaging adhesive 23 and the lamp panel 21, so as to reflect the light emitted by the lamp beads 22, improve the utilization rate of the light source, and improve the light-emitting rate of the backlight source.
In the second method, the light emitted from the lamp beads 22 is diffused by adding a diffusion material to the transparent encapsulation paste 23 or forming the transparent encapsulation paste 23 to have a certain haze.
