Abstract
This utility model discloses an LED display screen based on COB packaging, including a cabinet and multiple COB LED modules arrayed at the front end of the cabinet. A control circuit board is disposed inside the cabinet, and each COB LED module has a module interface corresponding to its mounting position. Each COB LED module has a module connector on its back that plugs into the module interface. A first magnetic element is disposed at each of the four corners of the front end of the cabinet corresponding to the mounting position of each COB LED module, and a second magnetic element is disposed at each of the four bottom corners of each COB LED module, magnetically connected to the first magnetic element. This utility model effectively solves the problems of time-consuming and labor-intensive maintenance, low resolution and clarity, excessive thickness, poor heat dissipation, and poor protection.
