Abstract:
A display apparatus is disclosed for enabling a user to experience a 3D perception when visual information is presented by the display apparatus. The display apparatus has an image forming unit having a two-dimensional array of image subpixels arranged to emit light for presenting associated visual information, and an optical system having an array of diffractive optical elements associated with respective ones of the array of image subpixels. Each diffractive optical element is arranged to diffract light from the associated image subpixel into a diffraction pattern with a plurality of diffraction orders to provide the visual information from the associated image subpixel to a plurality of directional viewing regions associated with the plurality of diffraction orders.
