ABSTRACT:
An organic light emitting display having color-specific demultiplexers is disclosed. Each demultiplexer receives a data signal for a specific color and sequentially supplies the data signals to sub-pixels for the specific color. Therefore, a data driving circuit supplying the data signal to the demultiplexer receives and successively processes only data of the specific color, so that power loss due to data charging/discharging operations is reduced when specific color sub-pixels of neighboring pixels receive the data signal corresponding to similar gray-scale voltages.
