Abstract
A pixel circuit, a driving method of a pixel circuit and an organic light-emitting display device are provided. The pixel circuit includes a first transistor having a gate electrode receiving a first light-emitting signal, a first terminal receiving a first reference voltage, and a second terminal connected to a first node; a second transistor having a gate electrode receiving a first scanning signal, a first terminal receiving a second reference voltage, and a second terminal connected to a second node; a third transistor having a gate electrode connected to the second node, a first terminal connected to a third node and a second terminal connected to a fourth node; a fourth transistor having a gate electrode receiving a second scanning signal, a first terminal receiving a data signal, and a second terminal connected to the third node; a fifth transistor having a gate electrode receiving the second scanning signal, a first terminal connected to the fourth node, and a second terminal connected to the second node; a sixth transistor having a gate electrode receiving a second light-emitting signal, a first terminal receiving a first power supply voltage, and a second terminal connect…
