Abstract: A pixel circuit and an electroluminescent display apparatus are discussed. The pixel circuit can include a driving transistor having a gate electrode connected to a gate node and a source electrode connected to a source node, and configured to generate a driving current. The pixel circuit can further include a first light emitting device having a first anode electrode, a second light emitting device having a second anode electrode, a first emission transistor connecting the source node to the first anode electrode in an odd frame and disconnecting the source node from the first anode electrode during an even frame in response to a first emission signal, and a second emission transistor connecting the source node to the second anode electrode in the even frame and disconnecting the source node from the second anode electrode during the odd frame in response to a second emission signal.
