摘要： A pixel includes a first transistor generating current from a first power source line to a second power source line through a light-emitting element, a second transistor between a third power source line and a gate electrode of the first transistor, a third transistor between a data line and a gate electrode of the second transistor and controlled by a first signal, a fourth transistor between a fourth power source line and a first node and controlled by a second signal, a first capacitor between the gate electrode of the first transistor and the first node, and a second capacitor between the gate electrode of the second transistor and a sweep voltage line providing a sweep voltage that linearly changes from a first voltage level to a second voltage level, and nonlinearly changes from the second voltage level to a third voltage level when the third transistor is on.

摘要： A display device includes: active stages each include a scan output circuit outputting a scan clock signal to a first output terminal and a carry output circuit outputting a carry clock signal to a second output terminal, when a voltage of a first node is at a logic high level. The scan output circuit and carry output circuit output a scan signal of a turn-off level to the first output terminal when a voltage of a second node or a carry signal is at a logic high level. An interval between pulses of the carry clock signal generated during one frame period is the same, and at least two of intervals between pulses of the scan clock signal generated during the one frame period are different from each other.
