Radian-variable LED arc-shaped screen

Abstract

The invention discloses a radian-variable LED arc-shaped screen, and belongs to the field of LED display screens. The radian-variable LED arc-shaped screen comprises a plurality of flexible lamp panels, a plurality of bottom shells, a box body and a power module. The flexible lamp panels and the power module are installed on the bottom shells to form display modules. The display modules are installed on the box body to form the LED display screen. The flexible lamp panels are transversely installed on the bottom shells in the length direction. The bottom shells are transversely arrayed in the width direction. The longitudinal arrangement width of the flexible lamp panels is matched with the length of the bottom shells. The transverse arrangement width of the bottom shells is matched with the length of the flexible lamp panels. The problem that splicing seams between the modules are large when the LED arc-shaped screen is formed by splicing the small-interval LED display modules is solved. Meanwhile, the defects that the radian of a traditional arc-shaped LED display screen can not be flexibly regulated, disassembly and assembly are complex and modules are heavy are overcome, application of the small-interval arc-shaped LED display screen in different occasions is achieved, and wide market prospects are achieved.

Description

technical field [0001] The invention relates to a display screen, in particular to a curved LED screen with variable radian, which belongs to the field of LED display screens. Background technique [0002] In the existing arc-shaped LED display products, basically one bottom case corresponds to one light board. When the arc is adjusted after the light board and the bottom case are assembled, the gap between the modules will be wide because the modules are arranged horizontally. If it is too large, it will affect the visual effect of the whole screen, and it cannot be used for small-pitch LED display products at all. In addition, the existing curved LED display modules cannot be separated from the cabinet and can only be used for fixed installation. [0003] In addition, the connection method of the curved components used in the existing curved LED display products is basically fixed by screwing, which is very troublesome to install, and the strength cannot be adjusted, an...

Problems solved by technology

[0006] In view of the defects existing in the prior art, the object of the present invention is to provide a curved LED screen with variable radians, which can solve the problem of large joints between modules of small-pitch LED curved screens. At the same time, it also solves the defects of inflexible adjustment of the curvature of the traditional LED curved screen, cumbersome disassembly and assembly, and bulky modules, and realizes the application of small-pitch LED curved screens in different occasions, which has broad market prospects

[0008] Aiming at the problem that the large gap between the modules cannot be applied on the small-pitch LED curved screen, this invention changes the traditional arrangement of the bottom case and the lamp board, and adopts a horizontal arrangement of the bottom case and a longitudinal arrangement of the lamp boards. When assembling the curved screen, the gap between the modules is greatly reduced, which can be applied to small-pitch curved screens, and when fixed installation is used, it can also be separated from the box and directly use the mold group for assembly
