Abstract: This embodiments herein relate to an organic light emitting diode display device comprising: a display panel configured to include a plurality of pixels disposed in a matrix form, wherein each of the pixels including: a driving TFT, an organic light emitting diode, a control circuit including first to fourth TFTs, capacitors. The embodiments described herein may improve accuracy of sensing a threshold voltage of the driving TFT even though the organic light emitting diode display device drives high frequency such as 240 Hz because sensing periods are long enough to sense the threshold voltage of the driving TFT. Also, the embodiments described herein may compensate a drop of a high potential voltage due to compensating the current between a drain electrode and a source electrode of the driving TFT by using the high potential voltage dropped.
