Abstract:
A voltage compensation pixel circuit includes a driving transistor coupled to the light emitting element between a high potential power line and a low potential power line to drive the light emitting element in response to a predetermined voltage applied to a gate, switching transistor including a first switching transistor being switched in response to a voltage of a first gate signal, a second switching transistor and a third switching transistor being switched in response to a voltage of a third gate signal, and a fourth switching transistor being switched in response to a voltage of a second gate signal, a storage capacitor coupled between a first node and a second node, and a setup transistor coupled between the light emitting element and the driving transistor and operated by the driving transistor. The first node is coupled to the driving transistor. The second node is coupled between the second switching transistor and the fourth switching transistor.
