Abstract: Provided are a backlight unit and a holographic display apparatus including the same. The backlight unit includes a light guide plate; an input coupler configured to guide light into the light guide plate; a light deflector configured to deflect light emitted from the input coupler and guide the deflected light to propagate within the light guide plate. The light deflector is disposed on a region of the light guide plate which does not overlap with an optical path of light incident on the input coupler. The backlight unit also includes an output coupler configured to emit the light, having been propagated within the light guide plate, to an outside of the light guide plate.

Abstract: A holographic display apparatus capable of steering a location of a viewing window according to a location of an observer is disclosed. The holographic display apparatus includes a light source; a spatial light modulator configured to modulate incident light and thereby reproduce the holographic image; a spatial filter configured to transmit only the holographic image; an eye tracker configured to track a pupil location of an observer; and a controller configured to adjust locations of the light source and the spatial filter in response to a change in the pupil location of the observer received from the eye tracker. The controller is configured to move the light source and the spatial filter simultaneously in the same direction by the same distance.

Abstract: A projection display apparatus that tracks a user's eye with an eye tracker and displays a high-resolution image at a position of the user's eye. The projection display apparatus includes an eye tracker configured to track an eye of a user; a projector configured to project an image; and a controller configured to control the projector, based on a position of the eye of the user obtained from the eye tracker, to perform a first operation to project a first portion of the image at a first resolution onto a first region with respect to the position of the eye of the user, and to perform one of a second operation to project a second portion of the image at a second resolution lower than the first resolution onto a second region excluding the first region, and a third operation to refrain from projecting the image in the second region.

Abstract: See-through type display apparatuses and electronic apparatuses including the same are disclosed. A see-through type display apparatus may include a multipath optical member that transfers a plurality of images along a plurality of paths to an ocular organ of a user, and an anisotropic optical member that is arranged between the multipath optical member and the ocular organ of the user. The anisotropic optical member may exhibit characteristics which vary based on a polarization direction of incident light. For example, the anisotropic optical member may function as a lens with respect to light that propagates along a first path and function in a different manner than the lens with respect to light that propagates along a second path. The anisotropic optical member may function as a flat plate with respect to the light that propagates along the second path.
