Abstract: A display device includes a transmissive display module and an optical control member which provides light emitted from a light source to the transmissive display module. The optical control member includes a barrier member and a focus control member coupled to a surface of the barrier member. The barrier member includes a polymer-dispersed liquid crystal layer to transmit or reflect the light incident thereto based on an arrangement of liquid crystal droplets therein. A left-eye barrier pattern and a right-eye barrier pattern are formed at different time points by controlling the arrangement of the liquid crystal droplets.

Abstract: Disclosed is a display device. A display panel outputs a first image in a first mode and outputs a second image in a second mode. A switch lens array is placed on the display panel and outputs the first image as a two-dimensional (2D) image in the first mode and converts the second image into a three-dimensional (3D) image in the second mode. A driving controller receives an image signal, converts the image signal into 2D image data based on a reference gamma value, and converts the image signal into 3D image data based on a correction reference gamma value different from the reference gamma value. A driving controller includes a gamma selection unit that selects one correction gamma value among a plurality of correction gamma values as the correction reference gamma value depending on predetermined depth information of the 3D image.

Abstract: A hologram display device includes a light source unit, a light guide plate, a spatial light modulator, a sensing unit, and a light source driving unit. The light source unit includes a plurality of light sources and emits light when at least one of the plurality of light sources is turned on. The light guide plate converts the light emitted thereto from the light source unit to a planar light beam. The spatial light modulator spatially modulates the planar light beam to produce a hologram image. The sensing unit senses a position of a user watching the hologram image, and the light source driving unit turns on the at least one of the plurality of light sources, based on information on the position of the user obtained by the sensing unit.

Abstract: A display device includes a substrate, a first set of light emitting structures, a second set of light emitting structures, a diffraction layer, and a refraction pattern. The substrate includes a first region and a second region. The first set of light emitting structures overlaps the first region. The second set of light emitting structures overlaps the second region. The diffraction layer overlaps the first region without overlapping the second region. The refraction pattern overlaps the diffraction layer. The diffraction layer includes first-refractive-index members and second-refractive-index members that are alternately disposed. A refractive index of each of the first-refractive-index members is lower than a refractive index of each of the second-refractive-index members.
