A display apparatus comprises a display panel (1) including a plurality of subpixels (101,102,103). Each subpixel comprises a first region (1010, 1020, 1030) for displaying a subpixel image. The display apparatus further includes a plurality of pixel adjustors (20) each of which is configured to adjust the first region of a corresponding one subpixel to display an initial subpixel image. Additionally, the display apparatus includes a plurality of optical elements at a first side of the display panel. Each of the plurality of optical elements (30) is associated with at least one subpixel to generate a virtual subpixel image (201, 202, 203) at a second side of the display panel corresponding to the initial subpixel image displayed by the at least one subpixel. Each of the plurality of optical elements independently controls a distance of the virtual subpixel image relative to the display panel and the second side is opposite to the first side.
