As described in the background, for tiled display devices, the seam width is a significant concern in the industry. For the splicing display device with the metal frame for bending, the width of the bent edge can influence the width of the splicing seam and the stability of the display panel. When the backlight source is in a high-temperature state, the backlight source can expand outwards, the display panel is mainly made of glass, and the expansion amount is extremely small, so that the narrower the bending edge width of the metal frame is, the greater the risk that the display panel jumps after the backlight source expands at high temperature is. Therefore, when the width of the bent edge is wide, the risk of jumping off of the display panel can be effectively avoided, but the width of the abutted seam is too wide, so that the display effect is influenced; when the width of the bent edge is narrow, the width of the abutted seam can be effectively reduced, the display effect is ensured, and the risk that the display panel jumps off after the backlight expands at high temperature is increased. Therefore, in the prior art, in order to avoid the display panel from jumping off, the width of the bending edge is wide, so that the width of the abutted seam is large. In recent years, the spliced products with metal frames bent are continuously upgraded in the aspects of process, structure, optics and the like, the width of the spliced seam is continuously reduced, and spliced display devices with the widths of 5.5mm, 3.9mm and 3.5mm are produced in a large-scale mode successively, but the width of the spliced seam with the width of 3.5mm is still a larger size compared with other spliced display devices. Therefore, efforts are constantly made in the industry to reduce the width of the seam of the spliced product with the metal frame bending, but the research on the aspect is not further broken through because of the limitation of the risk of the display panel jumping.
