    摘要: A holographic display apparatus (100) includes: a light source (110) configured to emit light; a spatial light modulator (120) configured to sequentially display hologram patterns for modulating the light to thereby sequentially diffractively reproduce frames of hologram images based on the hologram patterns; and a controller (140) 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 prism grating diffraction patterns for adjusting transverse locations of the hologram images, wherein the periodic prism grating diffraction patterns move on the spatial light modulator along a predetermined direction for each of the frames.

    摘要: Provided is a backlight unit having high optical efficiency and a holographic display device (1000) including the backlight unit. The backlight unit includes a light source unit (100) configured to provide a light beam, a first beam expander (200, 201, ...) configured to mix the light beam provided from the light source unit, expand the light beam in a first direction (A1), and output the mixed and expanded light beam as white light (W), and a second beam expander (300) configured to expand the white light output from the first beam expander in a second direction (A2) perpendicular to the first direction and output the expanded white light as surface light for illuminating a spatial light modulator (600).
