Abstract
An organic light emitting display device and a method of driving the same. The organic light emitting display device includes a scan driver, a data driver for supplying data signals, and pixels. Each of the pixels is 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 is included for supplying the first power to a power line coupled to the pixels. A sensing resistor is coupled between the power supply and the power line. A power controller is provided for controlling the power supply to adjust a voltage value of the first power for controlling an amount of current that flows through the sensing resistor to be substantially equal to an amount of current corresponding to data of a current frame.
