Abstract
An organic light emitting display device using a multiplexer includes a display panel, a data driver, and a multiplexer. The display panel includes first to fourth data lines and first to fourth pixels respectively connected to the first to fourth data lines. The data driver includes a first output buffer supplying a data voltage to the first and third data lines and a second output buffer supplying a data voltage to the second and fourth data lines. The multiplexer distributes the data voltage from the first output buffer to the first and third data lines in a time division manner and distributes the data voltage from the second output buffer to the second and fourth data lines in a time division manner. The multiplexer connects a data line, which is not connected to the first and second output buffers, among the first to fourth data lines, to an initialization voltage line providing an initialization voltage.
