Abstract

A pixel (PX) includes a first transistor (T1) including a gate connected to a first node (N1), a first terminal, and a second terminal connected to the second node (N2), a third transistor (T3) which connects a sensing line (SL) to the second node, a fourth transistor (T4) which connects a power line (PL) to the first terminal of the first transistor, a first capacitor (C1), and a light-emitting element (LED). A frame period includes an active period (ACT) and a blank period (BLK). The blank period includes a sensing compensation period (PC_S) in which a threshold voltage of the first transistor is stored in the first capacitor, a sensing addressing period (PA_S) in which a sensing data voltage is applied to the first node, and a sensing period (PS) in which a sensing current corresponding to the sensing data voltage flows from the power line to the sensing line.
