Abstract:
A pixel circuit includes first to fifth transistors, an organic light emitting element, and a capacitor. The second transistor includes a control electrode receiving a first scan signal, an input electrode receiving a data voltage, and an output electrode connected to the control electrode of the first transistor. The third transistor includes a control electrode receiving a second scan signal, an input electrode receiving an initialization voltage, and an output electrode connected to the output electrode of the first transistor. The fourth transistor includes a control electrode receiving an emission signal, an input electrode receiving a first power voltage, and an output electrode connected to the input electrode of the first transistor. The fifth transistor includes a control electrode receiving a third scan signal, an input electrode receiving the data voltage, and an output electrode connected to the input electrode of the first transistor.
