The invention relates to an overvoltage drive device, a storage method thereof and a display device which the overvoltage drive device is applied to. The overvoltage drive device is applied to a liquid crystal display panel for receiving a plurality of pixel gray scale values corresponding to a pixel in a plurality of pictures and outputting a plurality of overvoltage driving gray scale values according to the pixel gray scale values. The overvoltage drive device comprises a pixel information processing unit for identifying the color of the pixel, a first storage device for storing the pixel gray scale values, a second storage unit for storing difference values compared with the plurality of pixel gray scale values stored in the first storage unit and an overvoltage drive selection correspondence unit respectively in electrically coupling with the pixel information processing unit, the first storage unit and the second storage unit and is used for selecting the first storage unit or the second storage unit co
