    Abstract: A holographic display apparatus includes a spatial light modulator configured to generate hologram patterns to modulate light; an illuminator configured to emit the light to the spatial light modulator; and a controller configured to control operations of the spatial light modulator and the illuminator, the spatial light modulator being configured to generate, from among the hologram patterns, a first hologram pattern and a second hologram pattern according to the control operations of the controller, the first hologram pattern and the second hologram pattern being configured to form a first hologram image and a second hologram image having different viewpoints, and the controller being configured to set a first phase modulation value of the first hologram pattern and a second phase modulation value of the second hologram pattern to be different from each other such that hologram images having different viewpoints are formed.

    Abstract: A multi-image display apparatus for augmented reality (AR) or mixed reality (MR) includes a diffractive optical lens element, an image forming device configured to form a first image including a first color image, a second color image, and a third color image, and an optical system configured to transfer the first image and a second image to the diffractive optical lens element, the second image transferred along a path different from a path of the first image. The optical system is configured to offset chromatic aberration of the diffractive optical lens element by providing different optical path lengths for the first color image, the second color image, and the third color image.

    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.
