PURPOSE: A system of controlling LEDs on an LED board is provided to improve the efficiency of the system by allow a user to change coordinate data of an LED module even when the arrangement of LEDs are changed. CONSTITUTION: An LED control system on an LED board includes an LED board(130), a storage(112), an LED coordinate register, a display unit, a data processing unit(110), and a controller(120).(X-Y) LEDs are arranged in one direction of horizontal and vertical direction and X LEDs are arranged in the other direction. The storage stores a plurality of images. The coordinate data of a plurality of LEDs are stored in the LED coordinate register. The display unit displays a selected one among a plurality of images. The data processing unit comprises a data controller(118) which selectively extracts(x-y) image data corresponding to LED coordination data.
