1. A double-vision display system, comprising:

  • a display displaying by displaying region-alternately and simultaneously the at least two images in an array area according to inputted video streaming;

    a polarization modulation device disposed in front of the display and modulating emitted light of the at least two images into kinds of polarized light having different polarization directions; and

    at least two pairs of polarization spectacles, polarization direction of each pair of polarization spectacles being the same as the polarization direction of one kind of the polarized light,whereinthe polarization modulation device includes;

    a polarizer,a first transparent substrate, anda second transparent substrate,wherein the polarizer is disposed between the display and the first transparent substrate and modulates emitted light of the display into polarized emitted light,the second transparent substrate is disposed at a side opposite to the polarizer of the first transparent substrate,two transparent conductive films are respectively formed on opposite surfaces of the first transparent substrate and the second transparent substrate,two alignment films are further respectively arranged on opposite surfaces of the two transparent conductive films, anda liquid crystal layer is filled between the two alignment films and liquid crystal in the liquid crystal layer is periodically twisted in synchronism with periodically switching in the at least two images of the display under driving of a switching signal supplied to the transparent conductive films;

    from the first transparent substrate side, the polarization modulation device comprising the first transparent substrate, the transparent conductive film, the alignment film, the liquid crystal layer, the alignment film, the transparent conductive film and the second transparent substrate in this order,wherein the two transparent conductive films respectively formed on the opposite surfaces of the first transparent substrate and the second transparent substrate are plane-shaped,wherein the two transparent conductive films continuously cover the opposite surfaces of the first transparent substrate and the second transparent substrate, respectively,wherein the display displays region-alternately and simultaneously the at least two images in a matrix form of a block shape,wherein in each row of display regions of the display, the at least two images are displayed region-alternately and simultaneously, and in each column of the display regions of the display, the at least two images are displayed region-alternately and simultaneously,wherein the display is a liquid crystal display, the liquid crystal display includes an array substrate and a color filter substrate bonded together, the polarizer of the polarization modulation device is directly used as an upper polarizer on the color filter substrate, the liquid crystal display and the polarization modulation device share the polarizer.
