PURPOSE: A pixel circuit, an organic light-emitting device including the same, and an operating method for the device are provided to simplify a circuit structure by omitting an operating circuit for changing a power voltage by operating the device in a simultaneous light emitting mode. CONSTITUTION: A pixel unit(20) is connected with a cross spot of a data line(Dm) and a scan line(Sn). The pixel unit receives a first power voltage(ELVDD) and a second power voltage(ELVSS) which are direct currents(DC). The pixel unit includes an operating transistor(Mdr), a first transistor(M1), a second transistor(M2), a first capacitor(C1), and a second capacitor(C2). An organic light-emitting diode(OLED) is connected with the pixel unit. A light-emitting control transistor(M3) is connected between the pixel unit and the organic light-emitting diode. |
