Abstract
A system for controlling a smart LED display board capable of compensating for luminance of an LED includes a luminance measurement unit which creates first luminance measurement data obtained by digitizing measured luminance of each LED, an image data input unit which receives first input data about each LED, a comparison unit which selects at least one first LED having a luminance value greater than a preset reference value, and creates a compensation power value compensating for the luminance value of the selected first LED; an image data compensation unit which receives the first input data and the compensation power value and creates second input data in which a power value that is contained in the first input data transmitted to the first LED is changed into the compensation power value; and a drive unit which transmits the second input data to the first LED.
