    摘要: A curved backlight unit is provided. The backlight unit includes a curved light guide plate having a curvature, a first light source configured to provide a first illumination light to a first surface of the curved light guide plate, an array of a plurality of different grating elements disposed on a second surface of the curved light guide plate and configured to allow the first illumination light to exit the curved light guide plate from the second surface, and a second light source configured to provide a second illumination light to a third surface facing the second surface of the curved light guide plate. The curved light guide plate includes a first area configured to allow the second illumination light to exist at a first intensity and a second area configured to allow the second illumination light to exist at a second intensity that is less than the first intensity

    摘要: A backlight unit for a holographic display is provided. The backlight unit includes: at least one light source; at least one input coupler; a light guide panel (LGP) that guides light; a first holographic element on a first surface of the LGP; and a second holographic element on a second surface of the LGP, wherein the at least one input coupler is configured to uniformly transmit rays emitted from the at least one light source toward the first holographic element through the LGP, and the LGP is configured to transmit the rays incident from the at least one input coupler toward the first holographic element, and the first holographic element redirects the rays toward the second holographic element, the redirected rays being substantially parallel to one another, and the second holographic element emits rays incident from the first holographic element toward an outside of the LGP.
