Abstract: The scalable LED display system has multiple scalable pre-assembled display blind panels to construct a display screen to meet the customer demands of various display sizes. An image controlling device is electronically connected to the LED display screen to drive the LED display screen. Therefore, the present invention simplifies the wiring from an image controlling device to thousands or millions of LED chips of the display screen, resulting in the simplification of the wiring and savings in time and effort for assembly, disassembly, and installation of the display system.
