Abstract
A pixel includes a light-emitting element including a first electrode and a second electrode connected to a low power line which transmits a low power voltage, a pulse width modulator which controls an emission time duration of the light-emitting element based on a data voltage and a sweep signal, and a constant current generator which supplies a driving current having a constant level to the light-emitting element based on a constant current generation voltage. The sweep signal has a first high voltage level in a non-emission period, and is boosted to a second high voltage level, which is higher than the first high voltage level, before decreasing to a low voltage level lower than the first high voltage level in an emission period.
