ABSTRACT:
An organic electroluminescent display and a demultiplexer, wherein the organic electroluminescent display comprising: a plurality of pixels displaying an image corresponding to output data current; a plurality of scan lines to transmit a scan signal to the plurality of pixels; a plurality of output data lines to transmit the output 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 demultiplexing circuit; and a data driver outputting input data current to the demultiplexer, wherein the demultiplexing circuit transmits the input data current after applying pre-charging voltage to the output data line selected among the output data lines in sequence. With this configuration, the present invention provides an organic electroluminescent display and a demultiplexer, in which comprises a current programming type pixel circuit uniformizing brightness of a screen even if threshold voltage is not uniform, and the demultiplexer placed between a data driver and an organic electroluminescent display panel, thereby reducing time taken to program data of a current programming type pixel.
