    Abstract: A backlight unit and a holographic display apparatus including the same are provided. The backlight unit includes a light guide plate and a uniformity changing element. The uniformity changing element has a light-incident surface and a light-exiting surface facing the light-incident surface, and the uniformity changing element receives the light output from the light guide plate through the light-incident surface, changes uniformity of the received light from the light guide plate and outputs the received light with the change in the uniformity of the received light through the light-exiting surface.

    Abstract: An apparatus and method for recognizing a fingerprint are provided. The apparatus includes a display device including a plurality of pixels configured to be turned on and off based on an image signal, a transparent cover disposed on the display device, the transparent cover including a touch surface through which a touch of a user is input, and a touch sensor configured to recognize a location of the touch through the touch surface. The apparatus further includes a fingerprint sensor configured to detect light that is reflected from the touch surface, based on the fingerprint of the user inputting the touch, and generate a signal, based on the light, and a controller configured to generate the image signal to turn on pixels corresponding to the location among the plurality of pixels, and determine a fingerprint profile of the fingerprint, based on the signal generated by the fingerprint sensor.

    Abstract: A light deflector includes a first light deflecting member disposed on a transparent substrate and has a refractive index that varies depending on a magnitude of an electric field applied thereto. The light deflector may adjust the refractive index by applying electric fields differently according to regions of the first light deflecting member or time divisions. The light deflector may have a smaller size than a light deflector including an optical device, and may easily adjust the refractive index.

    Abstract: A holographic display apparatus includes: a light source configured to emit light; a spatial light modulator configured to sequentially generate hologram patterns for modulating the light and to sequentially reproduce frames of hologram images based on the hologram patterns; and a controller 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 diffraction patterns for adjusting locations of the hologram images to be reproduced on a hologram image plane, the diffraction pattern data signals being configured to move the periodic diffraction patterns on the spatial light modulator along a predetermined direction for each of the frames.

    Abstract: A display including an electrowetting prism array is provided. The display includes: a light source, a 2-dimensional (2D) display for providing an image using light from the light source, a prism array in which a refractive power of one or more prisms of the prism array is adjustable in real time, and an optical element which increases a refraction of light transmitted therethrough. In the display, the optical element may be disposed in front of or behind the prism array. The optical element may be a convex lens, a Fresnel lens, a holographic optical element (HOE), a diffraction optical element (DOE), or a second electrowetting prism array. The convex lens may be a variable focus lens.
