Folded support, display, keyboard, and electrical appliance. Folded support comprises a limit structure and folds connected by rotating connection structure and are expandable and foldable. The limit structure ensures the front sides of the folds to be in a same plane in the expanding state of folded support; the rotating connection structure comprises a first and/or second rotating connection structures, the folds connected by the first rotate to get front sides close to each other, the folds connected by the second rotate to get rear sides close to each other; in folding state, a circle formed with the minimum bending radius of a flexible film is contained in the space from end sides of the folds connected by the first to the rotation axis, the end sides of folds connected by the second match up with a flexible film or have a gap to the flexible film.
