Abstract: Provided are a display device, a drive circuit, and a driving method. An accurate threshold voltage compensation value is calculated by finely and incrementally correcting the threshold voltage compensation value in real time during display driving. Consequently, a threshold voltage is accurately and rapidly compensated for.

Abstract: A light emitting display apparatus includes a substrate, a passivation layer disposed over the substrate, a light emitting device layer including a light emitting layer disposed over the passivation layer, a non-emission pattern portion including a light emitting material pattern disposed over the passivation layer at a periphery portion of the substrate and electrically isolated from the light emitting layer, and an encapsulation layer disposed over the light emitting device layer and the non-emission pattern portion. The encapsulation layer may wholly surround the non-emission pattern portion and seals an interface between the non-emission pattern portion and the passivation layer.
