Pixel Driving Circuit and Electroluminescent Display Device Including the Same

Abstract:

Disclosed are a pixel driving circuit and an electroluminescent display device including the same. The pixel driving circuit in each of the pixels includes: a first switching circuit that turned on in response to the (n-2)th scan signal to provide a V1 voltage to a first node, provide a V3 voltage to a third node, and provide a V2 voltage 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 V5 voltage 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.
