The invention discloses soft display equipment and supporting devices. The soft display equipment comprises the two supporting devices and soft display screens mounted on the two supporting devices; each supporting device comprises a double-shaft-type driving module and two buffering modules located on the two opposite outer sides of the double-shaft-type driving module correspondingly; each double-shaft-type driving module comprises two shaft rods and a linkage piece, wherein the two shaft rods are parallelly arranged in a spaced mode, and the linkage piece is clamped between the two shaft rods; and each buffering module comprises an inner connecting piece fixed to the corresponding linkage piece, an outer connecting piece oppositely and slidably arranged on the inner connecting piece, and a link mechanism which can be driven by a linkage rod to drive the outer connecting piece to move relative to the inner connecting piece. When the double-shaft-type driving modules of the two supporting devices rotate synchronously, the soft display screens are bent, the total length remains constant, and the outer connecting piece in each buffering module moves relative to the corresponding inner connecting piece, so that through moving of the outer connecting pieces relative to the inner connecting pieces, the supporting devices are prevented from stretching the soft display screens.
