1. A multi-screen display apparatus, comprising a first display screen, a second display screen and a first prismatic structure optical element, whereinthe first display screen and the second display screen are arranged adjacent to each other, a first included angle is formed between the first display screen and the second display screen, the first included angle is greater than 90 degrees and less than 180 degrees, and the first display screen and the second display screen each have a display area and a frame surrounding the display area;

  • the first prismatic structure optical element is disposed between the first display screen and the second display screen and covers two side edges adjacent to each other in the frames of the first display screen and the second display screen and a part of the display areas, the first prismatic structure optical element comprises a substrate and a plurality of prism pillars adjacent one another disposed on the substrate, and an extending direction of each of the prism pillars is substantially parallel to the two side edges adjacent to each other;

    wherein the display area of the first display screen comprises a first main display area, a first sub display area and a second sub display area that are sequentially arranged, the display area of the second display screen comprises a second main display area, a third sub display area and a fourth sub display area that are sequentially arranged, the fourth sub display area is adjacent to the second sub display area, wherein the first sub display area, the second sub display area, the third sub display area and the fourth sub display area are covered by the first prismatic structure optical element, the first main display area is adapted to display a first part of a first image frame, the first sub display area and the fourth sub display area are adapted to respectively display a second part of the first image frame adjacent to the first part, the second main display area is adapted to display a first part of a second image frame, and the second sub display area and the third sub display area are adapted to respectively display a second part of the second image frame adjacent to the first part;

    the first main display area comprises a first block and a second block, the first block is covered by the first prismatic structure optical element, the second block is outside the coverage of the first prismatic structure optical element, an image displayed by the second block is a compressed image without compression in a width direction, an image displayed by the first block and the first sub display area is a compressed image compressed in the width direction, so that after being enlarged by the first prismatic structure optical element, the image displayed by the first block and the first sub display area has a ratio same as the image displayed by the second block in the width direction;

    an image displayed by the second sub display area is a compressed image compressed in the width direction, and a compression ratio thereof is the same as that of the compressed image displayed by the first block and the first sub display area;

    the multi-screen display apparatus further comprises an image processing module for providing a calibration interface displayed on the first display screen for a user to define a range of the first block plus the first sub display area.
