Description

Hologram display device {Hologram display device}

The present invention relates to a hologram display device, and more particularly, the user rotates an exhibition object to be promoted and displayed on the hologram display device, and outputs a hologram image around the exhibition object, thereby increasing visibility and publicity effect. It relates to a hologram display device having a.

In recent years, as technology for providing 3D stereoscopic images has developed, products or services that provide various types of realistic images such as 3D TV or hologram performances are emerging.

In the above method, the image is provided in consideration of the difference in the perspectives viewed by the left and right eyes, and it is an electronic method such as 3D TV to provide different images recognized by the left and right eyes through special glasses.

On the other hand, the hologram is made by recording the interference pattern between the reference light and the object light by injecting the reference light and the light reflected from the object on which the information is to be recorded, that is, the object light.

The floating image method has recently been commercialized as a form of providing a 3D effect using holographic technology, so that the image projected on a transparent or translucent film is overlapped with the background image. It provides a three-dimensional effect through the distance difference, and since Dennis Garbor first invented the hologram, the most common method until now is the two beam transmission hologram developed by E, Leith. and One beam reflection hologram developed by Denisyuk and Edge-lit hologram developed by N, Phillips.

Among them, there is provided a technology for reflecting and synthesizing an image using a reflective film so that the viewer can recognize it as a hologram to display it in three dimensions.
