<p>The present invention is to provide an organic light emitting display device which can effectively control overcurrent flowing through a display panel. The organic light emitting display device according to the present invention comprises: a display panel composed of a plurality of pixels including an organic light emitting device emitting light by current corresponding to data voltage; and a panel driving unit predicting a panel current value flowing through the display panel by analyzing current horizontal line data of a current frame which is inputted per horizontal period, calculating a brightness gain value for the current horizontal period to control the predicted panel current value to be below an overcurrent limit value, and modulating the current horizontal line data in accordance with the calculated brightness gain value and displaying the modulated data in the display panel.</p> |
