More Information
Summary:The flexible organic light emitting display device includes a panel (100), a data driver (310) configured to drive data lines included in the panel, a gate driver (200) configured to drive gate lines included in the panel, a sensing unit (320), and a controller (400). The sensing unit senses 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 (110) 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 senses the characteristic change of the driving transistor or analyzes whether the panel is bent, based on pieces of sensing data transferred from the sensing unit.
