According to the present invention, an organic light-emitting display (OLED) device comprises: a display panel, wherein formed are a plurality of pixels including an operation thin film transistor (TFT) to control an amount of a current flowing in an OLED, according to a voltage difference between data voltage supplied by a data line and the OLED, and reference voltage supplied by a reference line; a source driver integrated circuit (IC) generating data voltage corresponding to input image data in order to apply the data voltage to data lines connected to the pixels; an image analysis unit analyzing the input image data to generate reference voltage control data; and a reference voltage control unit generating reference voltage which varies depending on an input image based on the reference voltage control data, and applying the reference voltage to the reference lines connected to the pixels. The purpose of the present invention is to offer the OLED device to improve an image grade. |
