Abstract
A pixel may include: an OLED; a first transistor having a first electrode connected to a power line receiving a first power, the first power changes to an initial voltage, a reference voltage, and a high voltage, the first transistor controlling the amount of current supplied to the OLED; a second transistor connected between a data line and a second node and turned on when a scan signal is supplied to a scan line; a third transistor connected between a gate electrode and a second electrode of the first transistor and having a turn-on time partially overlapping the turn-on time of the second transistor; a fourth transistor, connected between the second node and the power line, and having a turn-on time not overlapping the turn-on time of the second transistor; and a storage capacitor connected between the gate electrode of the first transistor and the second node.
