1. An electroluminescent display panel, comprising:
a plurality of pixels arranged along a row direction and a column direction, each of the plurality of pixels including a first sub-pixel of a first color, a second sub-pixel of a second color, and a third sub-pixel of a third color;
a first emission line that, in operation, transmits an emission signal to the first sub-pixels of a first row of pixels of the plurality of pixels that are arranged along the row direction; and
a plurality of emission stages including a first set of emission stages that is connected to the first emission line and a second set of emission stages that is not connected to the first emission line and is connected to a next emission line of a next stage, the plurality of emission stages being arranged in a column direction of the display panel;
wherein a number of the plurality of emission stages is greater than or equal to twice a number of the plurality of pixels arranged along the column direction, and
wherein two emission stages of the first set of emission stages are connected with three sub-pixel rows.
