Abstract: A method for sensing degradation of an organic light emitting display includes an initialization step for applying a sensing data voltage to a gate node of a driving TFT and applying an initialization voltage to a source node of the driving TFT, a boosting step for floating the gate node and the source node of the driving TFT and applying a drain-to-source current of the driving TFT to an organic element, a sensing step for again applying the initialization voltage to the source node of the driving TFT, setting a gate-to-source voltage of the driving TFT depending on a degradation degree of the organic element, and storing the drain-to-source current of the driving TFT determined by the set gate-to-source voltage in a line capacitor, and a sampling step for outputting a voltage stored in the line capacitor as a sensing voltage.

Abstract: The present disclosure relates to a large area ultra high density flat panel display having a high aperture ratio. The present disclosure provides a flat panel display including a driving current line and a sensing line disposed in a first direction on a substrate; a scan line and a sensing gate line disposed in a second direction on the substrate; a horizontal current line disposed at upper side of the scan line in the second direction and connected to the driving current line; a horizontal sensing line disposed at lower side of the sensing gate line in the second direction and connected to the sensing line; a common current line branched from the horizontal current line and crossing the scan line; and a first pixel area and a second pixel area disposed between the driving current line and the sensing line as having a bi-symmetric shape with each other based on the common current line.
