An OLED display device includes an OLED display panel (110) on which subpixels (SP) are disposed, a gamma reference voltage supply circuit (1350) supplying gamma reference voltages that are variable during driving and when sensing a threshold voltage, and a data driver (120) supplying data voltages based on the gamma reference voltages to data lines (DL). The data driver (120) senses a voltage of a sensing node (N2) within each of the subpixels (SP) in sensing mode. A timing controller (140) controls the data driver (120), and performs a compensation process based on the voltage sensed by the data driver (120). |
