ABSTRACT:
Disclosed is an organic light emitting display that reduces the number of output lines and adjusts a white balance. A scan driver supplies scan signals to a plurality of scan lines. A data driver supplies data signals to a plurality of output lines. Demultiplexers are installed at the respective output lines, and supply the data signals to the plurality of data lines. Data capacitors are coupled with the data lines, and charge a voltage corresponding to the data signals. An image display device is coupled with the scan lines and the data lines, and includes red pixels having a red organic light emitting diode, green pixels having a green organic light emitting diode, and blue pixels having a blue organic light emitting diode. A first initialization power supply supplies a first voltage to the red pixels. A second initialization power supply supplies a second voltage to the green pixels. A third initialization power supply supplies a third voltage to the blue pixels. Voltages of the first, second, and third initialization power supplies are differently set, respectively.
