Abstract:
A pixel includes a first transistor connected between a line supplying a power supply voltage and a second node, and providing a driving current corresponding to a data voltage to a light emitting element based on a voltage of a first node, a third transistor connected between the first node and a line supplying a reference voltage, and generating a sampling current based on a difference between a voltage of the second node and the reference voltage, a second transistor connected between the line supplying the power supply voltage and the first node, adjusting the voltage of the first node to generate the sampling current based on a voltage of a third node, a fourth transistor transferring the power supply voltage to the third node, a fifth transistor transferring the data voltage to the second node, and a capacitor connected between the first node and the third node.
