PURPOSE: An LED display panel is provided to minimize power consumption by establishing color temperature duty ratio based on color of multimedia data. CONSTITUTION: An LED panel(100) arranges a plurality of light source cells. The plurality of light source cells is respectively composed of a first light source, a second light source, and a third light source having different color temperature. The LED panel is placed on a frame. A control module(200) comprises a data receiver(210), a data analyzer(220), a duty ratio setting unit(230), and a power supplying unit(240). The data receiver receives multimedia data from outside. The data analyzer analyzes the inputted multimedia data according to color. The duty ratio setting unit establishes color temperature duty ratio based on the analyzed color. The power supplying unit supplies a power source to the first light source, the second light source, and the third light source according to the established color temperature duty ratio. |
