Abstract: A vibration apparatus may include a vibration plate, a vibration generator at the vibration plate, and a connection member between the vibration plate and the vibration generator. The vibration generator may include a vibration structure. The connection member may include a first connection member between the vibration plate and the vibration structure and overlapping the vibration structure. The connection member may also include a second connection member surrounding the first connection member. A modulus of the first connection member may be greater than a modulus of the second connection member.

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.
