Abstract: An icosahedral LED display screen belongs to the field of display screens and includes multiple cabinet main frames. Each cabinet main frame is formed with an accommodating cavity. A side of each cabinet main frame is provided with a flexible PCB, an outer side of the flexible PCB is disposed with LEDs, and an inner side of the flexible PCB is provided with a magnet fixedly therewith. The multiple e.g., twenty cabinet main frames are mutually connected to form an icosahedral sphere which has no end point similar to a football, and polygons that make up the sphere are the same, and therefore the cabinet main frames can be completely covered by the flexible PCBs to eliminate a missing of display at an endpoint and reduce design numbers and complexities of the cabinet main frames and the flexible PCBs. An installation of the LED display screen becomes more convenient.
