Abstract

An organic light emitting display includes a display panel including first pixels displaying a first color, second pixels displaying a second color, and third pixels displaying a third color, a data driving circuit generating a data voltage, a demultiplexer (demux) switching circuit, which includes first to Nth demux switches connected to each output channel of the data driving circuit, where N is a positive integer equal to or greater than 2, and time-division supplies the data voltage to N data lines of the display panel, and a control signal generator generating first to Nth demux control signals for controlling operations of the first to Nth demux switches. The first to Nth demux control signals sequentially rise to an on-level and then sequentially fall to an off-level in a programming period, in which a scan signal is held at the on-level.
