Abstract:
1. An organic light emitting diode display device comprising: a plurality of first sub-pixels, the plurality of first sub-pixels having first light emitting elements emitting first color light and first driving transistors to drive current through the first light emitting elements; a first reference voltage line to provide a first reference voltage to source electrodes of the first driving transistors; a plurality of second sub-pixels, the plurality of second sub-pixels having second light emitting elements emitting second color light and second driving transistors to drive current through the second light emitting elements; a plurality of third sub-pixels, the plurality of third sub-pixels having third light emitting elements emitting third color light and third driving transistors to drive current through the third light emitting elements; a plurality of fourth sub-pixels, the plurality of fourth sub-pixels having fourth light emitting elements emitting fourth color light and fourth driving transistors to drive current through the fourth light emitting elements; and a second reference voltage line to provide a second reference voltage to source electrodes of the second driving transistors, to source electrodes of the third driving transistors, and source electrodes of the fourth driving transistors.
