Abstract: An image display device includes a main light source configured to emit a first light; a display panel configured to modulate the first light to add image information to the first light; a holographic optical element (HOE) configured to diffract the first light emitted from the display panel to make the first light travel to a first region to generate a main image; a first optical system provided on a traveling path of the first light between the main light source and the HOE, the first optical system being configured to change the traveling path of the first light to be incident on the HOE along a first path; an auxiliary light source configured to emit a second light; and a second optical system provided on a traveling path of the second light, the second optical system being configured to change a traveling path of the second light to be incident on the HOE along a second path different from the first path.

Abstract: A holographic display apparatus and a holographic display method are provided. The holographic display apparatus determines a representative depth from 3D image data; calculates a computer generated hologram (CGH) corresponding to the representative depth on the 3D image data; obtains the modulated CGH by modulating a phase of the CGH to increase an eye box; modulates a light according to the modulated CGH and generates a hologram image; and forms the generated hologram image at the representative depth.

Abstract: A display apparatus may include: an image generator configured to generate an image by using light; a holographic optical element configured such that when a single image is incident as reference light on the holographic optical element, the holographic optical element focuses a plurality of images corresponding to the single image on spatially different points as signal light; and an image deflector configured to deflect the image received from the image generator to the holographic optical element in a given direction.
