An apparatus for displaying a hologram comprises: a hologram display panel that represents light having the hologram images to an observer; a detecting camera that decides a position of the observer; a deflector that forms a prism pattern to refract the light corresponding to the detected position of the observer; and a deflector driver that supplies a driving voltage corresponding to a inclined angle for forming the prism pattern, wherein the deflector includes: a plurality of first electrodes running to a first direction and divided into a plurality of electrode groups; a plurality of connection electrodes running to a second direction crossing with the first direction, and connecting same numbered first electrodes of the electrode groups, wherein each end of the connection electrodes forms a pad portion; and a second electrode facing to the plurality of the first electrodes with a liquid crystal cell therebetween.

Apparatus for displaying a hologram

A spatial light modulating panel using a transitive liquid crystal display panel and a three-dimensional display device using the same. A a spatial light modulator including a plurality of pixels arrayed in a matrix manner; and a liquid crystal layer configured to modulate phase of an incident light passing through the each pixel, respectively. The spatial light modulator and the 3D display using the same provides a thin flat type display system having an easy and simple structure and a low manufacturing cost.

Spatial light modulating panel using transmittive liquid crystal display panel and 3D display device using the same

The present disclosure relates to a digital hologram display device displaying 3D image as a hologram by using a complex modulation. The digital hologram display device comprising a spatial light modulator including a first pixel outputting a first modulation light by modulating a phase of a first plane-polarized light and a second pixel outputting a second modulation light by modulating the phase of the first plane-polarized light, wherein the second pixel is adjacent to the first pixel; and a light combiner changing a path of the first modulation light outputted from the first pixel so that the path of the first modulation light corresponds to a path of the second modulation light outputted from the second pixel for combining the first modulation light with the second modulation light, wherein a phase of the first modulation light is different from a phase of the second modulation light.

Digital hologram display device

The present disclosure relates to a dual holography three dimensional display device. The present disclosure suggests thin flat type holography 3D display device comprises: a left-eye display panel for representing a left-eye 3D image; and a right-eye display panel disposed at one side of the left-eye display panel for representing a right-eye 3D image. By combining the left-eye holography display panel with the right-eye holography display panel, it is possible to suggest high quality and high speed processed holography 3D images/video without expensive high speed processing display panel.

Dual holography 3D display device

The present disclosure relates to a digital hologram display device in which the 0diffraction component is removed for optimizing the reproduction and replay of three-dimensional hologram video data. The present disclosure suggests a digital hologram image display device including a pattern generator generating holography interference patterns; a spatial light modulator receiving the holography interference patterns from the pattern generator and representing the holography interference patterns; a light source positioning at one side of the spatial light modulator and illuminating a reference beam to the spatial light modulator; an optical device controlling the reference beam to be collimated onto the entire surface of the spatial light modulator; and a diffusion sheet disposed between the light source and the spatial light modulator.
