Abstract
Disclosed is a pixel circuit and a display apparatus having the same. The pixel circuit includes a first node connected to a VDD line to which a first constant voltage is applied; a third node connected to a fourth node connected to a light-emitting element; a fourth-first switch element arranged between the VDD line and the first node; and a fourth-second switch element arranged between the VDD line and the first node. An initialization phase, a sampling phase, an addressing phase, and an emission phase during a driving step are repeatedly performed. The fourth-first switch element and the fourth-second switch element are PWM-driven in the emission phase. With this configuration, a display apparatus with improved Mura may be provided.
