Description

Technical Field

[0001] The utility model relates to the technical field of display screens, and more specifically, to an LED display screen integrated board group. Background Art

[0002] The LED display integrated board assembly is generally made by installing several display screen components on a frame through bolts, then installing the integrated board on the frame through bolts, and electrically connecting it and several display screen components together to form an LED display integrated board assembly. However, in this method, when each display screen assembly is installed, in order to ensure the installation stability, it needs to be connected to the frame by at least three bolts to ensure that when one of the bolts falls off, the display screen can still be fixed in place, which will lead to a long installation time, a cumbersome installation process, and an equally cumbersome, time-consuming and laborious disassembly process. In addition, when some display screen assemblies are installed, they are mutually clamped by adjacent display screen assemblies and frames. For example, when some display screen assemblies are installed, the display screen assembly in the lower left corner is first fixed to the frame, and then the display screen assemblies above it are installed in sequence, so that they are clamped in sequence. After the entire column is installed, the display screen assemblies in the right column are installed, and finally the display screen assembly in the upper right corner is installed and fixed to the frame, thereby realizing the installation and fixation of the display screen assembly. However, when a certain display screen assembly needs to be disassembled or replaced, it is necessary to disassemble several display screen assemblies in reverse order until the required display screen assembly is disassembled. This method is time-consuming and laborious. Utility Model Content
