Displacement temporary storage device

The invention discloses a displacement temporary storage device comprising multistage displacement temporary storage circuits; each displacement temporary storage circuit comprises a first switch, an input circuit, a pull-down circuit and a ripple suppression circuit, wherein the first switch is used for outputting scanning signals of the temporary storage circuit according to electric potentials of nodes and clock signals. The input circuit is used for receiving the scanning signals output by a preceding stage displacement temporary circuit and is used for pulling up the electric potentials of nodes of the corresponding stage displacement temporary storage circuit according to the scanning signals. The pull-down circuit is used for pulling down the electric potentials of node and scanning signals of the corresponding stage displacement temporary storage circuit according to scanning signals output by a rear stage displacement temporary storage circuit. The ripple suppression circuit is used for suppressing ripples which are generated when the electric potentials of the nodes and the scanning signals of the corresponding stage temporary storage circuit are coupled by the clock signals.
