Patent ID: 10062321

Abstract:
A pixel circuit includes a first-transistor including gate-electrode receiving first emission control signal, first-electrode connected to ELVDD, and second-electrode connected to first node, a second-transistor including gate-electrode receiving second emission control signal, first-electrode, and second-electrode connected to second node, a third-transistor including gate-electrode connected to third node, first-electrode connected to first node, and second-electrode connected to first-electrode of the second-transistor, an OLED including anode connected to second node and cathode connected to ELVSS, a fourth-transistor including gate-electrode receiving bias scan signal, first-electrode connected to initialization voltage, and second-electrode connected to second node, a fifth-transistor including gate-electrode receiving bias scan signal, first-electrode connected to reference voltage, and second-electrode connected to third node, a sixth-transistor including gate-electrode receiving data scan signal, first-electrode receiving data signal, and second-electrode connected to third node, a storage-capacitor between first node and third node, and a hold-capacitor between ELVDD and first node.
