Abstract

A display apparatus is disclosed, which includes a pixel. The pixel includes first through fifth transistors and a light emitting element. The first transistor includes a control electrode electrically connected to a first node, an input electrode that receives a first power voltage and an output electrode electrically connected to the light emitting element. The second transistor includes a control electrode that receives a scan signal, an input electrode that receives a grayscale data voltage and an output electrode electrically connected to a second node. The third transistor includes a control electrode electrically connected to the second node, an input electrode that receives a reference voltage and an output electrode electrically connected to the first node. The fourth transistor includes a control electrode that receives the scan signal, an input electrode that receives a bias data voltage and an output electrode electrically connected to the first node. The fifth transistor includes a control electrode that receives a sensing control signal, an input electrode that receives an initialization voltage and an output electrode electrically connected to the light emitting element.
