Abstract: Provided is a foldable rotation shaft, including: a base, a first support mechanism, and a second support mechanism. In an unfolded state, the base, the first support mechanism, and the second support mechanism are respectively configured to support a bending portion, a first portion, and a second portion of the flexible display panel. The second support mechanism is configured to cause, in a folded state, a region, proximal to the base, of the second portion to be bent into a curved shape along a direction going away from the first support mechanism. The first support mechanism is configured to cause, in the folded state, a curvature of a partial region of the first portion to be different from a curvature of the region, bent into the curved shape, of the second portion. The partial region is opposite to the region, bent into the curved shape, of the second portion.
