[0002] With the continuous development of LED display technology, small-pitch LED displays, due to their high definition, low brightness, and high grayscale levels, have gradually become the mainstream display device in fields such as outdoor advertising, stage rental, and sports stadiums. Among small-pitch LED displays, COB (Chip On Board) technology is widely used in the manufacturing of LED displays due to its advantages such as high-density integration and excellent optical properties.
[0003] However, existing COB fine-pitch LED displays still have certain problems with their splicing technology. For example, the dense arrangement of LED components in fine-pitch LED displays often results in relatively obvious splicing gaps between adjacent screens, which not only affects the overall visual effect but also the viewing experience.
[0004] In addition, the COB small-pitch LED display screen also has the problem of poor heat dissipation inside the screen body. The screen temperature is too high, which will affect the service life and stability of the display screen. Utility Model Content
