Summary:PURPOSE: An energy-saving LED display board for programming driving power by LED increases the efficiency of maintenance by programming and setting the intensity of driving power supplied to R, G, and B elements of a color LED. CONSTITUTION: An LED module has color LEDs arranged in a matrix form. A power supply unit (10) supplies driving power to R, G, and B elements of the color LED through a switching device controlling the intensity of output driving power. A driving unit (20) controls the operation of the R, G, and B elements of the color LED. A control unit programs and sets the intensity of driving power of the power supply unit by controlling the switching of the switching device.
