Abstract: The present invention relates to a bending adjustment apparatus using a curved bar, a bendable electronic device including the same, and a method for adjusting bending of the electronic device. The bending adjustment apparatus according to the present invention includes: a guide unit attached to a flat panel member made of a flexible material; at least one curved bar extending in a curved shape and rotatably installed in the guide unit; and a power transmission drive unit configured to rotate the curved bar so as to adjust a tensile force applied to the flat panel member corresponding to a curved shape of the curved bar. Accordingly, the degree of bending of the panel may be controlled by adjusting an angle formed by the curved direction of the curved bar with the panel in a state in which the bent-type curved bar is coupled to the flat panel member such as a display panel, and the curvature of the panel may be adjusted to a desired degree by controlling the rotation of the curved bar to an arbitrary angle.
