The driving transistor T1 may output a driving current Id to the light-emitting element OLED according to the gate-source voltage. A magnitude of the driving current Id is determined based on a voltage difference between the gate-source voltage of the driving transistor T1 and a threshold voltage. The light-emitting element OLED may receive the driving current Id from the driving transistor T1 and emit light of a brightness according to the magnitude of the driving current Id.
The scan transistor T2 transfers the data voltage Dm_j to the source S of the driving transistor T1 in response to the first scan signal GW_i. The scan transistor T2 may include a gate connected to the first scan line GWL_i, a source S connected to a data line DL_j, and a drain D connected to the source S of the driving transistor T1.
The first and second compensation transistors T3a and T3b are connected in series with each other between the drain D and gate of the driving transistor T1, and connect the drain D of the driving transistor T1 to the gate of the driving transistor T1 in response to the first scan signal GW_i. The first compensation transistor T3a may include a gate connected to the first scan line GWL_i, a source S connected to the drain D of the driving transistor T1, and a drain D connected to a source S of the second compensation transistor T3b. The second compensation transistor T3b may include a gate connected to the first scan line GWL_i, a source S connected to the drain D of the first compensation transistor T3a, and a drain D connected to the gate of the driving transistor T1.
