摘要:
A pixel circuit includes a first driving transistor including a gate electrode connected to a first node, a first electrode to receive a first power voltage, and a second electrode connected to a second node, a second driving transistor including a gate electrode and a second electrode connected to the second node, a first electrode to receive the first power voltage, and a back gate electrode connected to the first node, a write transistor including a first electrode to receive a data voltage and a second electrode connected to the first node, an initialization transistor including a gate electrode to receive an initialization gate signal, a first electrode to receive an initialization voltage, and a second electrode connected to the second node, a storage capacitor connected to the first and second nodes, and a light emitting element connected to the second node and configured to receive a second power voltage.
