Abstract:
1. An organic light emitting display device comprising: a scan driver for supplying a scan signal to scan lines during scan periods of a plurality of sub-frames included in one frame; a data driver for supplying data signals to data lines when the scan signal is supplied; pixels at crossing regions of the scan lines and the data lines, each of the pixels configured to control whether or not a current flows from a first power to a second power both coupled to the pixels, the current corresponding to a corresponding one of the data signals; a power supply for supplying the first power to a power line coupled to the pixels; a sensing resistor coupled between the power supply and the power line; and a power controller for controlling the power supply to adjust a voltage value of the first power to correspond to an amount of current that flows through the sensing resistor and data of a current frame, wherein the power controller comprises:
