Abstract:
A backlight unit for a holographic display is provided. The backlight unit includes: at least one light source; at least one input coupler; a light guide panel (LGP) that guides light; a first holographic element on a first surface of the LGP; and a second holographic element on a second surface of the LGP, wherein the at least one input coupler is configured to uniformly transmit rays emitted from the at least one light source toward the first holographic element through the LGP, and the LGP is configured to transmit the rays incident from the at least one input coupler toward the first holographic element, and the first holographic element redirects the rays toward the second holographic element, the redirected rays being substantially parallel to one another, and the second holographic element emits rays incident from the first holographic element toward an outside of the LGP.
Abstract:
An apparatus and a method for displaying holographic 3D image are provided. The method includes generating, by a controller, a hologram signal to generate multiple identical hologram images which are shifted with respect to one another by a predetermined distance and overlapped on one another, and modulating, by a spatially light modulator (SLM), light incident on the SLM based on the hologram signal.
Abstract:
A holographic display includes: a light source; at least one beam steerer configured to control a propagation direction of a beam emitted from the light source; an optical element configured to condense a beam passing through the at least one beam steerer; and a spatial light modulator configured to form a three-dimensional (3D) image by modulating a beam passing through the at least one beam steerer.
Abstract:
An apparatus for driving a display panel including a plurality of cells coupled to a plurality of gate lines and a plurality of data lines, a gate driver configured to output a gate selection signal to a shared gate line, and a data driver configured to output data signals to the cell array. The shared gate line includes a first gate line and a second gate line, the first and second gate lines sharing the gate selection signal.
Abstract:
Provided are a complex spatial light modulator and a three-dimensional (3D) image display apparatus. The complex spatial light modulator includes a spatial light modulator configured to modulate a phase of light, a first prism array which is disposed after the spatial light modulator along a path of the light, and including prism units each having a first prism surface and a second prism surface, and a hologram optical device configured to diffract the light that has passed through the first prism array independently from a polarization of the light, where the first prism array and the hologram optical device are configured to modulate the phase and an amplitude of the light.
