Light emitting display device capable of minimizing a current driving capability deviation among driving switching elements
Abstract:
Disclosed is a light emitting display device capable of minimizing a current driving capability deviation among driving switching elements. The light emitting display device includes pixels each including a first TFT for supplying data voltage to a first node in response to a scan signal, a second TFT for forming a current path between first and second nodes in response to an emission control signal, a driving TFT for forming a current path between a first driving voltage supply line and a third node in accordance with a voltage level of the second node, a third TFT for supplying a reference voltage to a fourth node in response to a sensing signal, a fourth TFT for supplying an initialization voltage to the third node in response to an initialization signal, and a fifth TFT for supplying the reference voltage to the second node in response to the initialization signal.
