Patent ID: 7800557

Claim:
An organic electroluminescent display device, comprising: a first organic electroluminescent element; a second organic electroluminescent element; a third organic electroluminescent element; a first driving transistor to apply a first driving current to the first electroluminescent element; a second driving transistor to apply a second driving current to the second electroluminescent element; a third driving transistor to apply a third driving current to the third electroluminescent element; a first switch connected between a first electrode of the first organic electroluminescent element and a first electrode of the first driving transistor; a second switch connected between a first electrode of the second organic electroluminescent element and a first electrode of the second driving transistor; a third switch group connected between a first electrode of the third organic electroluminescent element and a first electrode of the third driving transistor; a first light emission control line to transfer a first light emission control signal; and a second light emission control line to transfer a second light emission control signal, wherein the first switch is turned on/off in response to the first light emission control signal, the second switch is turned on/off in response to at least one of the first and second light emission control signals, and the third switch group is turned on/off in response to the first and second light emission control signals.
