Abstract
A pixel circuit includes a first transistor, a second transistor operating based on a gate control signal, a third transistor operating based on a compensation control signal, a fourth transistor operating based on a previous gate control signal, fifth and sixth transistors operating based on an emission control signal, a seventh transistor operating based on a bias control signal, an eighth transistor operating based on the bias control signal, a storage capacitor, and a light emitting element connected to the first transistor. The pixel circuit performs one display-scan operation when a driving time of a panel driving frame is a minimum driving time and performs one display-scan operation and at least one self-scan operation when the driving time is not the minimum driving time.
