    Abstract: An augmented reality device may include: a light source; a display device comprising a plurality of pixels and configured to generate a first image based on light incident from the light source; and an optical combiner comprising a plurality of optical combining units each including a first area and a second area, wherein the first area reflects a plurality of beams constituting the first image at different reflection angles according to wavelengths and incident angles and transfers the reflected plurality of beams to a predetermined viewer position, and the second area transmits a beam of a second image received from outside and transfers the beam of the second image to the predetermined viewer position.

    Abstract: Provided is a multi-image display apparatus including a light source configured to emit a first wavelength light, a second wavelength light, and a third wavelength light, a spatial light modulator configured to modulate the first wavelength light, the second wavelength light, and the third wavelength light to form a first image including a first color holographic image, a second color holographic image, and a third color holographic image, a polarization selective lens configured to focus the first image having only a first polarization component and transmit a second image having only a second polarization component without refraction, the second image being provided to the polarization selective lens along a different path from the first image, wherein chromatic aberration of the polarization selective lens is offset by adjusting a depth of the first color holographic image, the second color holographic image, and the third color holographic image.

    Abstract: Provided is 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.
