Organic light emitting display having demultiplexers and parasitic capacitances

Abstract

An organic light emitting display that reduces the number of output lines from a data driver, attains image stability, and adjusts white balance. A plurality of demultiplexers at the primary output lines of the data driver simultaneously supply the data signals from each primary output line to a plurality of secondary output lines allowing a reduced number of primary output lines. A plurality of parasitic capacitors are formed where data lines are coupled with the pixels and are charged to a voltage corresponding to the data signal that is simultaneously provided to the pixels allowing an image of uniform brightness to be displayed. The scan period and the data period are not overlapping allowing a stable image. Capacitance values of data capacitors are set taking into consideration the light emitting efficiency of organic light emitting diodes, allowing an image of adjusted white balance.
