Abstract:
1. A method of driving an organic electroluminescent display device, comprising: sequentially outputting from a prior shift register first and second prior gate signals to first and second pixels on first and second row lines, respectively, wherein: outputting from a post shift register a first post gate signal to the first pixel using the first and second prior gate signals, wherein the first post gate signal has an on-state when an on-state of the first prior gate signal is completed and the second prior gate signal has an on-state; and switching a switching device according to the first prior gate signal; and switching a driving device according to the first post gate signal, wherein the number of lines for prior gate signals is more than the number of lines for post gate signals; wherein the first prior gate signal and the first post gate signal are applied to the same first row line, and on and off states of the first prior gate signal and the first post gate signal alternate.
