A driving circuit and an OELD device using the same are provided to enhance signal characteristics by setting a precharge voltage between first and second reference voltages. An OELD(Organic Electro Luminescence Display) device includes a pixel unit, and data and scan drivers. The data driver includes a first decoder(251), switch units(252,253), a second decoder(254), and a gray scale voltage generator(255). The first decoder generates a first selection signal in response to a data signal. The switch units receive plural first and second voltage from first and second buses, select the first or second voltages in response to the data signal, and select plural first and second reference voltages from the first or second voltages. The second decoder generates a second selection signal in response to the data signal. The gray scale voltage generator receives the first or second voltages, generates plural gray scale voltages by separating the first or second voltages, and outputs one of the gray scale voltages in response to the second selection signal.
