Abstract
The present invention relates to an organic light emitting diode display device which minimizes a temperature increase of an organic light emitting panel in consideration of an input image and an external environment, the organic light emitting diode display device comprising: an organic light emitting panel; a power supply unit for supplying a current to the organic light emitting panel; a control unit for performing an automatic current limit for controlling the maximum value of the current supplied to the organic light emitting panel to be less than or equal to the current limit value; and a temperature sensor for sensing the temperature of the organic light emitting panel, wherein the control unit may change the current limit value according to the present temperature of the organic light emitting panel.
