Organic electroluminescent display and demultiplexer

Abstract

An organic electroluminescent display and a demultiplexer, wherein the organic electroluminescent display comprises: a plurality of pixels including a plurality of sub-pixels and displaying images corresponding to a first data current; a plurality of scan lines transmitting a scan signal to the plurality of pixels; a plurality of first data lines transmitting the first data current to the plurality of pixels; a scan driver outputting the scan signal to the plurality of scan lines; a demultiplexer comprising a plurality of sample-and-hold demultiplexing circuits; and a data driver outputting a second data current to a plurality of second data lines, wherein the demultiplexing circuit transmits the first data current, obtained by demultiplexing the second data current in sample/hold method, to the first data lines, wherein a pre-charge voltage corresponding to the second data current is previously transmitted to the first data lines before the first data current is transmitted to the first data lines.
