    Abstract: Discussed is a flexible organic light emitting display device. The flexible organic light emitting display device according to an embodiment includes a panel, a data driver configured to drive data lines included in the panel, a gate driver configured to drive gate lines included in the panel, a sensing unit, and a controller. The sensing unit may sense bending of the panel in a blank period of one frame period by using a pixel driving circuit included in each of a plurality of pixels included in the panel, for sensing a characteristic change of a driving transistor driving an organic light emitting diode included in each of the plurality of pixels, the one frame period including the blank period and a display period. The controller may sense the characteristic change of the driving transistor or analyze whether the panel is bent, based on pieces of sensing data transferred from the sensing unit.
