Abstract
A pixel driving circuit in each of the pixels includes: a first switching circuit that is turned on in response to the (n−2)th scan signal to provide a Vvoltage to a first node, provide a Vvoltage to a third node, and provide a Vvoltage to an anode of the light-emitting element; a second switching circuit turned on in response to the nth scan signal to electrically connect the first node to a second node, provide a Vvoltage to the third node, and provide a data voltage to a fourth node; and an emission control circuit turned on in response to the nth emission signal to electrically connect a second node to the anode and provide a reference voltage to the fourth node.
