Abstract: A pixel circuit includes a light-emitting element, a first transistor, a second transistor operating based on a first gate signal, a third transistor operating based on a second gate signal, a fourth transistor operating based on an initialization control signal, a fifth transistor operating based on an emission control signal, a sixth transistor operating based on the emission control signal, a seventh transistor, of which one terminal is connected to the light-emitting element, operating based on a bias control signal, an eighth transistor, of which one terminal is connected to the driving transistor, operating based on the bias control signal, a storage capacitor, and the light-emitting element. The circuit performs a display-scan operation where a driving time of a panel driving frame is a predetermined duration, and performs a display-scan operation and a self-scan operation where the driving time is longer than the predetermined duration.

Abstract: A display device includes pixels, and each pixel is connected between a first electrode or a second electrode of a driving transistor and a bias line, includes a bias transistor configured to transfer a bias voltage applied from the bias line to the first electrode or the second electrode of the driving transistor during a bias period. Bias voltages applied to the pixels emitting light of different colors are different from each other.
