Description

Technical Field

[0001] The utility model relates to the technical field of LED display, in particular to a box body of an LED display screen and an LED display screen. Background Art

[0002] With the development of optoelectronic technology, LED displays are becoming increasingly popular. LED displays consist of a housing and multiple LED display modules mounted on it. Due to their large size and small thickness, LED display modules are prone to deformation after installation. This creates a gap between the LED display module and the housing, and electromagnetic radiation is easily generated in this gap. Existing LED displays typically eliminate electromagnetic radiation between the LED display module and the housing by straightening the module or by inserting conductive cotton between the module and the housing. However, straightening the LED display module is difficult and may cause PCB wiring to break. Inserting conductive cotton between the module and the housing raises the module surface, affecting the flatness of the LED display, and can easily cause the conductive cotton to fall off during assembly and disassembly.
