Claim Text:
1. An organic light emitting display device comprising: a pixel unit including pixels arranged at every intersection between data lines and scan lines; a data driving unit supplying data signals to the data lines; a scan driving unit supplying scan signals to the scan lines sequentially; an image analyzer analyzing an input image and outputting a maximum luminance level of the input image according to the analyzed result; a power voltage controller reading a voltage level corresponding to the maximum luminance level from a lookup table and outputting a power voltage control signal corresponding to the read voltage level; a power supply supplying a power voltage corresponding to the voltage level to the pixel unit via power lines in response to the power voltage control signal; and a corrector correcting the voltage level corresponding to the maximum luminance level stored in the lookup table based on a difference between a current flowing through the power lines and a current estimated in corresponding to the voltage level.
