Abstract: A holographic display apparatus includes: a light source configured to emit light; a spatial light modulator configured to sequentially generate hologram patterns for modulating the light and to sequentially reproduce frames of hologram images based on the hologram patterns; and a controller configured to provide hologram data signals to the spatial light modulator, the hologram data signals being used to sequentially generate the hologram patterns. The controller is configured to further provide, to the spatial light modulator, diffraction pattern data signals for forming periodic diffraction patterns for adjusting locations of the hologram images to be reproduced on a hologram image plane, the diffraction pattern data signals being configured to move the periodic diffraction patterns on the spatial light modulator along a predetermined direction for each of the frames.

Abstract: A see-through type display apparatus and a method of operating the see-through type display apparatus are provided. The see-through type display apparatus simultaneously outputs a plurality of two-dimensional (2D) images having different depth information onto different regions, produces a multi-layered depth image by sequentially arranging the plurality of 2D images according to the depth information, and causes the multi-layered depth image and a reality environment to converge onto one region.

Abstract: An apparatus and method for processing a holographic image are disclosed. The apparatus calculates a first calculation result with respect to an image for the left eye and a first calculation result with respect to an image for the right eye and stores the results at different memory addresses of a storage. Thereafter, the apparatus calculates values of a waveform of light to be modulated by a spatial light modulator by performing a second calculation that uses all of the first calculation results stored in the storage. An image window of the image for the left eye and an image window of the image for the right eye are spatially separated from each other by the apparatus in a viewing window of a hologram image reproduced via the spatial light modulator.

Abstract: Provided is a back light unit (BLU) for holographic display. The BLU includes a first diffraction grating attached to a waveguide, a second diffraction grating that supplies light to the first diffraction grating, a light source that supplies light to the second diffraction grating, and a light reflection element that reflects light towards the first diffraction grating. The back light unit may further include a lens that is disposed in front of the waveguide. The light reflection element may be disposed parallel to a rear surface of the waveguide. The light reflection element may be inclined with respect to the rear surface of the waveguide. The light reflection element may be a mirror or a prism array.
