Abstract:
The organic light emitting diode display device comprising a display panel a plurality of pixels arranged in a matrix form, each of the pixels comprising: a driving TFT including a gate electrode coupled to a first node, a source electrode coupled to a second node, and a drain electrode coupled to a high-potential voltage line; an organic light emitting diode including an anode coupled to the second node and a cathode coupled to a low-potential voltage line; a first TFT supplying a data voltage to the first node in response to a scan signal; a initialization control circuit initializing the first node to a first reference voltage and the second node or the third node to a second reference voltage in response to a initialization signal and an emission signal; and capacitors.
