PURPOSE: An e-commerce system for full-white light emitting diode(LED) color coordinate values is provided to sell and purchase corrected color coordinate values online, thereby enabling a user to control LED modules with desired color coordinate values. CONSTITUTION: A color coordinate database(116) stores corrected color coordinate values of each LED device. A registration unit(112) matches the corrected color coordinate values with supplier information and price information. The registration unit stores the matched information. A search unit(113) provides a search user interface for searching the corrected color coordinate values. A sale unit(114) provides a sale user interface based on the supplier information and the price information.
