description | An OLED display device is disclosed which includes: a display panel configured with pixels which each include an organic light emitting diode and a driving transistor applying a driving current to the organic light emitting diode; a gate driver connected to the pixels through gate lines; a data driver configured to apply a sensing voltage to the pixels through data lines in a sensing mode and enable a sensing current to flow through each of the driving transistors; a sensing driver configured to sense threshold voltages opposite the driving currents which flow through the driving transistors; and a brightness compensation circuit configured to derive negatively shifted degrees of threshold voltages of the driving transistors from the sensed threshold voltages, detect a bright-defected pixel on the basis of the negatively shifted degrees, and generate a compensation gray value for the bright-defected pixel. |
