Abstract
An organic light emitting display configured to be driven using a frame divided into a plurality of sub-frames includes a data driver configured to supply a plurality of data signals to output lines during a first period of one horizontal period of the sub-frame, a scan driver configured to sequentially supply a scan signal to scan lines during a second period of the one horizontal period of the sub-frame, a demultiplexer coupled to each output line, the demultiplexer being configured to supply the data signals to a plurality of data lines, buffers configured to supply buffers supplying signals from the demultiplexers to the data lines, the buffers including PMOS transistors, and pixels disposed at intersections of the scan lines and the data lines, the pixels being configured to display images corresponding to the data signals.
