Abstract
A near-to-eye display apparatus includes a plurality of pixel island groups. Each pixel island group includes a plurality of pixel islands. Each pixel island corresponds to a micro lens. By adjusting a position of the micro lens relative to the corresponding pixel island in the pixel island group, on a plane where the micro lenses are located, or a position, of the pixel island in the pixel island group relative to the corresponding micro lens, on a plane where the pixel islands are located, imaging points in the imaging regions formed by at least part of different pixel islands in the pixel island groups do not overlap with each other and are arranged alternately.
