Patent ID: 8432335

Claim:
An organic light emitting display device comprising: a demultiplexer controller for sequentially supplying i (i is a natural number greater than 2) control signals during a first period of a horizontal period and before a second period of the horizontal period; a plurality of scan lines for transferring a scan signal; a scan driving unit for supplying the scan signal to the scan lines during the second period of the horizontal period; a plurality of output lines for transferring a plurality of data signals; a data driving unit for sequentially supplying i of the data signals to respective output lines during the first period; a plurality of data lines for transferring the data signals; a plurality of demultiplexers coupled to the respective output lines, for delivering the i of the data signals to a respective i of the data lines in response to the i control signals; an initializing unit coupled to the data lines and an initial power source, for supplying a voltage of the initial power source to the data lines during a third sub-period of the second period; and a plurality of pixels located at crossing regions of the scan lines and the data lines and configured to be driven by receiving the data signals and the scan signal during a second sub-period of the second period, and by receiving the voltage of the initial power source during the third sub-period.
