Abstract
A display device comprises a pixel circuit including a driving element having a gate electrode connected to a first node and a source electrode connected to a second node, a light emitting element connected to the second node, a first switch element that connects a data line and the first node, and a second switch element that connects a reference voltage line and the second node; a gate driver that supplies a scan signal to the gate line; and a sensing circuit that senses a voltage of the reference voltage line during a sensing period, wherein during an initialization period the scan signal is higher than the sensing data voltage, during the sensing period, the scan signal is higher than the first ground voltage and lower than the sensing data voltage, during the sensing period, a voltage of the second node is stored in a sensing capacitor.
