Abstract
A pixel of a light-emitting display device includes a capacitor, a first transistor, a second transistor including a gate receiving a gate writing signal, a third transistor including a gate receiving a scan signal, a fourth transistor including a gate receiving a gate initialization signal, a fifth transistor including a gate receiving a first emission signal, a sixth transistor including a gate receiving a second emission signal, and a light-emitting diode. The scan signal and the gate writing signal may be provided at a first frequency, and the first emission signal, the second emission signal and the gate initialization signal may be provided at a second frequency higher than the first frequency.
