Abstract
A pixel according to some embodiments includes a light source unit, a first transistor coupled between a first power source and a first node, and configured to control a driving current applied to the light source unit, a first bias transistor coupled between a first bias power source and a gate electrode of the first transistor, and a second bias transistor coupled between a second bias power source and a second node that is electrically coupled to an anode of the light source unit, wherein the first bias transistor and the second bias transistor are configured to be turned on during a first period before a data voltage is applied among one frame, and wherein the second bias transistor is configured to be turned on at least once during a second period after the data voltage is applied among the one frame.
