Abstract
The organic light emitting display device according to the present invention includes a scan driver for supplying a scan signal to scan lines during a frame time-divided into a plurality of subframes, a data driver coupled to output lines for supplying data signals on each of the output lines, data distributors coupled to the output lines for distributing the data signals to data lines, concurrently, in synchronization with the scan signal, and pixels located at crossing regions of the data lines and the scan lines. Each of the data distributors includes a sampling latch for distributing the data signals to different channels and for storing the data signals, and a holding latch coupled to the sampling latch for supplying the data signals of the channels to the data lines concurrently.
