Abstract
A pixel circuit may include a first transistor that provides a data signal to a first node according to a scan signal, a second transistor that initializes the first node, a first capacitor that is coupled between one terminal to which a light emission signal is provided and the first node, a second capacitor that is coupled between the first node and a second node, a third transistor that includes a gate coupled to the second node and one terminal coupled to a third node, a fourth transistor that includes a gate coupled to the second node and one terminal coupled to the third node, a fifth transistor that is coupled between the second node and the third node, a drive transistor that includes a gate to which a voltage corresponding to the voltage at the third node is supplied, and a micro light emitting diode that is coupled to the drive transistor.
