Claim Text:
1. A display apparatus, comprising: a display module configured to provide a light beam; a variable parallax barrier module disposed on a transmission path of the light beam, the variable parallax barrier module respectively forming a plurality of different parallax barrier patterns during different display periods of a frame time, each of the parallax barrier patterns comprising a plurality of light-transmissive regions and a plurality of light-shielding regions alternately arranged along an arrangement direction, wherein any two adjacent light-transmissive regions in the light-transmissive regions of the parallax barrier patterns partially overlap each other, and the variable parallax barrier module comprises a plurality of first switching units and a plurality of second switching units alternately arranged along the arrangement direction, and in each of the display periods, each of the first switching units in a portion of the first switching units and two of the second switching units adjacently located at two sides of the each of the first switching units in the portion of the first switching units are switched into a light-transmissive state so as to form the light-transmissive regions, while the remaining first switching units and the remaining second switching units are switched into a light-shielding state so as to form the light-shielding regions; and a control unit enabling a plurality of display images displayed by the display module during the display periods to respectively correspond with the parallax barrier patterns.
