Abstract:
According to one exemplary embodiment of the present disclosure, the electroluminescent display panel may include a plurality of pixels arranged along a row direction and a column direction, an emission line transmitting an emission signal to the plurality of pixels arranged along the row direction and an emission driving circuit providing an emission signal to the plurality of pixels. The emission driving circuit includes a plurality of emission stages wherein the number of emission stages is more than the number of the plurality of pixels arranged along the column direction. Therefore, the pulse width resolution of the display panel may be enhanced and the low gradation stain may be reduced.
