Provided is an organic light emitting diode (OLED) display device including a plurality of pixels (P) to display images, each of the pixels (P) including an OLED, a driving transistor (DT) connected to the OLED, and a switching transistor (ST1, ST2) configured to supply data signals to the OLED, the device including: a sensing unit (30) configured to sense a change amount of a mobility of the driving transistor (DT); a compensation value calculator (41) configured to obtain a change amount of a threshold voltage of the driving transistor (DT) based on the sensed change amount of the mobility; and a data compensator (50) configured to adjust the data signals based on the sensed change amount of mobility and the obtained change amount of the threshold voltage. |
