Fig. 1 is a schematic structural diagram of an exemplary backplane assembly, as shown in fig. 1, the backplane assembly comprising: a back plate 101, and a light source structure 102 located on the back plate 101. When applied to a display panel, the light source structure 102 may provide a backlight source to implement the display function of the display panel. In practical applications, one side of the back plate 101 close to the light source structure 102 is generally a flat plane, the light source structure 102 can be attached to and fixed to the back plate 101 by means of manually adhering an adhesive tape, so that the back plate 101 can effectively fix and support the light source structure 102, and other optical devices such as an optical film layer can be further disposed on the light source structure 102, so that point-like or linear light rays can be converted into high-brightness and uniform-luminance planar light rays through the optical devices such as the optical film layer, and the display panel can normally display images.
At present, the thickness of the back plate 101 may be 0.2 millimeters (mm), but as the requirement of a user on a light and thin display product is higher and higher, the thickness of the back plate 101 is also thinner and thinner, the thickness of the back plate 101 may reach 0.15mm, even reach 0.1mm, the strength of the back plate 101 is affected to a certain extent, especially in a large-size display product, the degree of influence on the strength of the back plate 101 is greater, and thus the strength of the back plate 101 at present cannot meet the requirement of a large-size ultrathin display product. Moreover, in the process of manually pasting the adhesive tape, due to human errors, the back plate 101 and the light source structure 102 are prone to shift, so that air bubbles are prone to be generated between the adhesive tape and the back plate 101 and between the adhesive tape and the light source structure 102, the pasting plane is not flat, the quality of a display picture of a display product is prone to being affected, the yield and the production efficiency of the display product are affected, and the automatic production of the display product is not facilitated.
